Lost Your Bitcoin? Here Is How You Can Recover It ...

Ultimate glossary of crypto currency terms, acronyms and abbreviations

I thought it would be really cool to have an ultimate guide for those new to crypto currencies and the terms used. I made this mostly for beginner’s and veterans alike. I’m not sure how much use you will get out of this. Stuff gets lost on Reddit quite easily so I hope this finds its way to you. Included in this list, I have included most of the terms used in crypto-communities. I have compiled this list from a multitude of sources. The list is in alphabetical order and may include some words/terms not exclusive to the crypto world but may be helpful regardless.
2FA
Two factor authentication. I highly advise that you use it.
51% Attack:
A situation where a single malicious individual or group gains control of more than half of a cryptocurrency network’s computing power. Theoretically, it could allow perpetrators to manipulate the system and spend the same coin multiple times, stop other users from completing blocks and make conflicting transactions to a chain that could harm the network.
Address (or Addy):
A unique string of numbers and letters (both upper and lower case) used to send, receive or store cryptocurrency on the network. It is also the public key in a pair of keys needed to sign a digital transaction. Addresses can be shared publicly as a text or in the form of a scannable QR code. They differ between cryptocurrencies. You can’t send Bitcoin to an Ethereum address, for example.
Altcoin (alternative coin): Any digital currency other than Bitcoin. These other currencies are alternatives to Bitcoin regarding features and functionalities (e.g. faster confirmation time, lower price, improved mining algorithm, higher total coin supply). There are hundreds of altcoins, including Ether, Ripple, Litecoin and many many others.
AIRDROP:
An event where the investors/participants are able to receive free tokens or coins into their digital wallet.
AML: Defines Anti-Money Laundering laws**.**
ARBITRAGE:
Getting risk-free profits by trading (simultaneous buying and selling of the cryptocurrency) on two different exchanges which have different prices for the same asset.
Ashdraked:
Being Ashdraked is essentially a more detailed version of being Zhoutonged. It is when you lose all of your invested capital, but you do so specifically by shorting Bitcoin. The expression “Ashdraked” comes from a story of a Romanian cryptocurrency investor who insisted upon shorting BTC, as he had done so successfully in the past. When the price of BTC rose from USD 300 to USD 500, the Romanian investor lost all of his money.
ATH (All Time High):
The highest price ever achieved by a cryptocurrency in its entire history. Alternatively, ATL is all time low
Bearish:
A tendency of prices to fall; a pessimistic expectation that the value of a coin is going to drop.

He is now in the mentally ill meme hall of fame.
Block:
A package of permanently recorded data about transactions occurring every time period (typically about 10 minutes) on the blockchain network.

Records, or blocks, are chained to each other using a cryptographic signature. They are stored publicly and chronologically, from the genesis block to the latest block, hence the term blockchain. Anyone can have access to the database and yet it remains incredibly difficult to hack.
Bullish:
A tendency of prices to rise; an optimistic expectation that a specific cryptocurrency will do well and its value is going to increase.
BTFD:
Buy the fucking dip. This advise was bestowed upon us by the gods themselves. It is the iron code to crypto enthusiasts.

How DAO users can truly control their voting rights

How DAO users can truly control their voting rights
https://blockchaintopbuzz.medium.com/how-dao-users-can-truly-control-their-voting-rights-f945c9c6b65e
Aelf proposed a solution that gives the control of the voting rights back to users by classifying token permissions.
As of today, there are still few complete businesses. In addition to mining and building trading platforms, it is difficult to create a complete business model. Moreover, various trading platforms have gradually grown into enterprises with comprehensive products in the blockchain industry, including wallets, nodes, lending, mining pools, etc.
At the same time, cloud services can reduce the cost of building small exchanges, but they can also lead to big trading platforms monopolizing data. For example, some Internet companies provide free cloud services in order to collect more valuable data.
Currently, Ethereum, which has the richest DeFi ecosystem, is gradually upgrading to V2.0, and its consensus protocol will also be upgraded to PoS. Governance voting can be regarded as the most important feature in the PoS ecosystem.
This year, Yearn.Finance rose to sudden prominence. But due to the governance problem, its community members initiated a hard fork, resulting in YFII. Another DeFi project, YAM, had a unfixable rebase function error. The founding team apologized for the error and announced a ‘Migration Plan’, which will turn the project over to the community.
For a while, governance voting became all the rage. However, the increasingly bigger trading platforms have been criticized by users in governance voting. Is there a proper solution to handling the relationship between the trading platform and governance voting?

What will we lose when trading platforms monopolize the blockchain industry?

In June 2018, during the BP node election before the EOS mainnet launch, node voting began to have a crisis of confidence between token holders and the trading platform. it is widely believed that the top 20 holders of trading platform wallets held about 40% of all the EOS in circulation.
Since then, many trading platforms have enabled the “User Authorization” interface. EOS holders can authorize the token voting rights to the trading platform, who will vote on behalf of the users. The rule caused a backlash from users, forcing these trading platforms to change the rule immediately so that EOS holders could vote on their preferred BP nodes.
After the EOS BP node votes, whether the trading platform has the token voting right has been occasionally discussed, but fewhave noticed it.
Two years later, Justin Sun, founder of TRON, made a commercial acquisition of Steemit, a decentralized social networking platform. After the acquisition was announced, the Steemit community launched a soft fork to resist the project being controlled by TRON. However, Justin Sun voted with the support of trading platforms such as Binance, Huobi and Poloniex to prevent a soft fork.
After being questioned by users, Binance and Huobi said that they would no longer interfere in the voting of the Steemit community. However, hkdev 404 of the Steem community again reveived votes from Huobi accounts. It is said that nearly 40 million votes were cast during the incident, accounting for about 10% of the total circulation of STEEM tokens.
There is no doubt that when the trading platform monopolizes the industry, we will lose our voting right.
How do we defend our voting rights
The fact that the ownership of the tokens belongs to the holders is indisputable, but what about the voting rights of the tokens deposited on the trading platform? How can we defend our voting rights after trading platforms have monopolized the industry?

Trading Platform Model

Traditional centralized trading platforms will assign to each user a separate deposit address. After depositing, the depositedamount will be added into the cold wallet and hot wallet. When users want to withdraw their tokens, the trading platform will transfer the tokens out of the hot wallet. If there is insufficient balance in the hot wallet, then the tokens will be transferred from the cold wallet to the hot wallet, and then be withdrawn.
Under the traditional centralized trading platform model, once users transfer their tokens into a trading platform, it means thetoken ownership (including voting rights) is also transferred to that trading platform.
The aelf solution: classify token permissions and claim back voting rights
For the issue of “voting rights” between token holders and centralized trading platforms, aelf, a decentralized cloud computing blockchain network, has proposed a solution: to establish an aelf Centre Asset Management Contract on the chain. The contract can limit the funds entering the exchange and define different permissions to control the assets.
The main feature of the aelf Centre Asset Management Contract is to create the “Main Virtual Address of the Trading Platform”.
Each exchange has a main virtual address, which can only be used for transfer operation, but not for voting, trading and other operations. As a result, the exchange cannot misappropriate users’ assets for voting. At the same time, the assets of the primary virtual address are publicly available on the chain, which makes it more difficult for the exchange to misappropriate assets.
At the same time, the aelf Centre Asset Management Contract also has the function of “address definition”. The exchange can open different permissions to different addresses, such as opening different permissions according to the amount, transactions exceeding a certain amount can only be given the greenlight by using multiple signatures, and the assets can be frozen through the contract when the assets of the trading platform are stolen, etc.
For the users of the trading platform, the access of the trading platform to the aelf Center Asset Management Contract function will not undermine user experience. The virtual system address of the aelf Center Asset Management Contract will assign a virtual address to each user, which offers the same user experience as the traditional mode.
For the trading platform, each deposit address constructed by the virtual address system is generated by the algorithm and does not need to be carried out on the blockchain. This means that the trading platform does not need to manage a large number of private keys, and there is no risk that the private keys will be lost.
On the most important “voting rights” issue, the aelf Center Asset Management Contract will assign to each user a separate virtual address for voting:
Voting address = Hash (Exchange Main Address + Token + “VOTE”)
Voting process: the tokens are transferred from the main virtual address of the exchange to the special “voting address” for voting, and are then voted. After voting, the tokens are withdrawn from the voting address back to the main virtual address.
We can see that the aelf Centre Asset Management Contract proposed by aelf can improve the efficiency of the trading platform without affecting user experience. In addition, it solves the problem that users would lose their voting rights.
According to the data on Crypto Mode, the market value of PoS tokens has exceeded $33 billion without counting Ethereum. In the field of crypto, it is the biggest ecosystem next to Bitcoin. The most important function of PoS is vote staking. faced with bigtrading platforms, if the status quo continues, retail investors will gradually lose their “voting rights” that belong to them.

Comparison of Market Value of PoS tokens (Source: Crypto Mode)
The emergence of DAO offers an alternative to trading platforms who misappropriate users’ tokens, but it still can not change this situation. Of course, DAO will not die out. Small communities will still use DAO for community governance. The idea behind the design of aelf is to start from the underlying trading platform and solve this issue at the source. Whether the solution can work still takes time. However, as a member of the crypto industry, we should understand the importance of “voting rights”, and cannot allow the exchange to seize our rights at will.
Recently, aelf has also announced its DeFi plan, which includes a new blockchain 3.0 project with a large number of new technical features, such as cross chain function, virtual address and cloud services. Aelf also proposed a set of interoperability solutions with ERC-20 tokens. It can directly access the ETH ecosystem, allow ETH-based applications and wallets to directly access it, and maintain the interoperability with ETH. And aelf will provide a high-performance smart contract operation platform and cloud services that can support cross chain interaction. Users on major cloud servers can easily run aelf’s services and adjust the scale of cloud according to their own business needs.
The implementation of a slew of tools, cloud services and interoperability solutions developed by aelf means that centralized transactions can be directly connected to the aelf network, realizing one-click adaptation to the DeFi ecosystem. With aelf, CeFi and DeFi are able to learn from and complement each other.

Let's discuss some of the issues with Nano

Let's talk about some of Nano's biggest issues. I also made a video about this topic, available here: https://youtu.be/d9yb9ifurbg.
00:12 Spam
Issues
Potential Mitigations & Outstanding Issues
01:58 Privacy
Issues
  • Nano has no privacy. It is pseudonymous (like Bitcoin), not anonymous.
Potential Mitigations & Outstanding Issues & Outstanding Issues*
  • Second layer solutions like mixers can help, but some argue that isn't enough privacy.
  • The current protocol design + the computational overhead of privacy does not allow Nano to implement first layer privacy without compromising it's other features (fast, feeless, and scalable transactions).
02:56 Decentralization
Issues
  • Nano is currently not as decentralized as it could be. ~25% of the voting weight is held by Binance.
  • Users must choose representatives, and users don't always choose the best ones (or never choose).
Potential Mitigations & Outstanding Issues
  • Currently 4 unrelated parties (who all have a verifiable interest in keeping the network running) would have to work together to attack the network
  • Unlike Bitcoin, there is no mining or fees in Nano. This means that there is not a strong incentive for emergent centralization from profit maximization and economies of scale. We've seen this firsthand, as Nano's decentralization has increased over time.
  • Nano representative percentages are not that far off from Bitcoin mining pool percentages.
  • In Nano, voting weight can be remotely re-delegated to anyone at any time. This differs from Bitcoin, where consensus is controlled by miners and requires significant hardware investment.
  • The cost of a 51% attack scales with the market cap of Nano.
06:49 Marketing & adoption
Issues
  • The best technology doesn't always win. If no one knows about or uses Nano, it will die.
Potential Mitigations & Outstanding Issues
  • I would argue that the best technology typically does win, but it needs to be best in every way (price, speed, accessbility, etc). Nano is currently in a good place if you agree with that argument.
  • Bitcoin started small, and didn't spend money on marketing. It takes time to build a community.
  • The developers have said they will market more once the protocol is where they want it to be (v20 or v21?).
  • Community marketing initiatives have started to form organically (e.g. Twitter campaigns, YouTube ads, etc).
  • Marketing and adoption is a very difficult problem to solve, especially when you don't have first mover advantage or consistent cashflow.
08:07 Small developer fund
Issues
  • The developer fund only has 3 million NANO left (~$4MM), what happens after that?
Potential Mitigations & Outstanding Issues
  • The goal for Nano is to be an Internet RFC like TCP/IP or SMTP - development naturally slows down when the protocol is in a good place.
  • Nano development is completely open source, so anyone can participate. Multiple developers are now familiar with the Nano protocol.
  • Businesses and whales that benefit from Nano (exchanges, remittances, merchant services, etc) are incentivized to keep the protocol developed and running.
  • The developer fund was only ~5% of the supply - compare that to some of the other major cryptocurrencies.
10:08 Node incentives
Issues
  • There are no transaction fees, why would people run nodes to keep the network running?
Potential Mitigations & Outstanding Issues
  • The cost of consensus is so low in Nano that the benefits of the network itself are the incentive: decentralized money with 0 transaction fees that can be sent anywhere in the world nearly instantly. Similar to TCP/IP, email servers, and http servers. Just like Bitcoin full nodes.
  • Paying $50-$100 a month for a high-end node is a lot cheaper for merchants than paying 1-3% in total sales.
  • Businesses and whales that benefit from Nano (exchanges, remittances, merchant services, etc) are incentivized to keep the protocol developed and running.
11:58 No smart contracts
Issues
  • Nano doesn't support smart contracts.
Potential Mitigations & Outstanding Issues
  • Nano's sole goal is to be the most efficient peer-to-peer value transfer protocol possible. Adding smart contracts makes keeping Nano feeless, fast, and decentralized much more difficult.
  • Other solutions (e.g. Ethereum) exist for creating and enforcing smart contracts.
  • Code can still interact with Nano, but not on the first layer in a decentralized matter.
  • Real world smart contract adoption and usage is pretty limited at the moment, but that might not always be the case.
13:20 Price stability
Issues
  • Why would anyone accept or spend Nano if the price fluctuates so much?
  • Why wouldn't people just use a stablecoin version of Nano for sending and receiving money?
Potential Mitigations & Outstanding Issues
  • With good fiat gateways (stable, low fees, etc), you can always buy back the fiat equivalent of what you've spent.
  • The hope is that with enough adoption, people and businesses will eventually skip the fiat conversion and use Nano directly.
  • Because Nano is so fast, volatility is less of an issue. Transactions are confirmed in <10 seconds, and prices change less in that timeframe (vs 10 minutes to hours for Bitcoin).
  • Stablecoins reintroduce trust. Stable against what? Who controls the supply, and how do you get people to adopt them? What happens if the assets they're stable against fail? Nano is pure supply and demand.
  • With worldwide adoption, the market capitalization of Nano would be in the trillions. If that happens, even millions of dollars won't move the price significantly.
15:06 Deflation
Issues
  • Nano's current supply == max supply. Why would people spend Nano today if it could be worth more tomorrow?
  • What happens to principal representatives and voting weight as private keys are lost? How do you know keys are lost?
Potential Mitigations & Outstanding Issues
  • Nano is extremely divisible. 1 NANO is 1030 raw. Since there are no transaction fees, smaller and smaller amounts of Nano could be used to transact, even if the market cap reaches trillions.
  • People will always buy things they need (food, housing, etc).
  • I'm not sure what the plan is to adjust for lost keys. Probably requires more discussion.
Long-term Scalability
Issue
  • Current node software and hardware cannot handle thousands of TPS (low-end nodes fall behind at even 50 TPS).
  • The more representatives that exist, the more vote traffic is required (network bandwidth).
  • Low-end nodes currently slow down the network significantly. Principal representatives waste their resources constantly bootstrapping these weak nodes during network saturation.
Potential Mitigations & Outstanding Issues
  • Even as is, Nano can comfortably handle 50 TPS average - which is roughly the amount of transactions per day PayPal was doing in 2011 with nearly 100 million users.
  • Network bandwidth increases 50% a year.
  • There are some discussions of prioritizing bootstrapping by vote weight to limit the impact of weak nodes.
  • Since Nano uses an account balance system, pruning could drastically reduce storage requirements. You only need current state to keep the network running, not the full transaction history.
  • In the future, vote stapling could drastically reduce bandwidth usage by collecting all representative signatures up front and then only sharing that single aggregate signature.
  • Nano has no artificial protocol-based limits (e.g. block sizes or block times). It scales with hardware.
Obviously there is still a lot of work to be done in some areas, but overall I think Nano is a good place. For people that aren't Nano fans, what are your biggest concerns?

30+ Reasons Why Cryptocurrencies Are Worthless

1)It is possible to change the code through a miner vote or a fork and change the total supply or anything. DASH did it : they reduced the total supply from 84M to 18.9M a few years ago. They could also increase it to 999 Trillions if they wanted to so that millions of DASH are mined every week.

2)You can also fork bitcoin anytime , start over from 0 and claim it's the real bitcoin. (BCH , BSV , BTG , LTC , BCD etc)

3)Why would you pay $10,000 for a digital collectible unit called BTC when you can use BCH or TRX or LTC .. you name it. They work just as fine and cost less. There is no rarity like in gold.

4)Think of any amount you hold in ethereum as a gift card to use smart contracts on the ETH blockchain. Ridiculous. You’d rather hold a wal mart gift card or even simply cash.

5)Private keys may be bruteforced as we speak. Quintillions entries a second. When they’ll have enough bitcoins under control , they could move them all at once instantly.(At least 45,000 ETH have been stolen this way for now through ethereum bandit)SHA 256 is too old , bitcoin is 10 years old , it is not secure enough , quantum computing could potentially break it.

6)And that’s if people don’t find a way to create an infinite amount of coins to sell on exchanges.. it happened with monero , stellar , bitcoin , zcash , zcoin , eos , etc..

proofs :

“Bitcoin , Coindesk : “The Latest Bitcoin Bug Was So Bad, Developers Kept Its Full Details a Secret”an attacker could have actually used it to create new Bitcoin — above the 21 million hard-cap of coin creation — thereby inflating the supply and devaluing current bitcoins.”

Stellar : “Stellar Inflation: Glitch Leads to 2.25 Billion Extra XLM Printed”

Monero : “A bug in the Monero (XMR) wallet software that could enable fake deposits to exchanges has been recently brought to public attention through a Medium post”

Zcoin : Forged coins were created, but not exceeding 1% of the circulating supply. We will release further details on exact numbers when Sigma is released.

EOS : “Hackers Forge Billion EOS Coins to Steal Real Crypto From DEX “

Zcash : “Zcash Team Reveals It Fixed a Catastrophic Coin Counterfeiting Bug” etc..

7)Segwit , and especially Lightning network is a very complex technology and it will inevitably have flaws , bugs , it will be exploited and people will lose money. That alone can cause bitcoin to drop very low levels.

8)Then miners may be losing millions so they will stop mining , blocks may be so slow , almost no transaction will come though , and bitcoin may not have enough time to reach the next difficulty adjustement. This is reffered to as a death spiral. Then every crypto even those with no mining involved may crash hard.

9)Many crypto wallets are unsafe and have already caused people to lose all their investment , including the infamous “parity wallet”.

10)It is NOT trustless. you have to trust the wallet you’re using is not just generating an address controlled by the developper , you have to trust the node the wallet connects to is an honest node , you have to trust a Rogue state or organization with enough computing power will not 51% attack the network. etc..

11)Bitcoin is NOT deflationary. Bitcoins are created every blocks (roughly every 10 minutes) and you wil be dead by the time we reach the 21 million current hard cap.

12)Bitcoin price may artificially be inflated by Tether.

13)It’s an energy waste , an environmental catastrophy.

14)The only usecases are money laundering , tax evasion , gambling , buying on the dark net , evading sanctions and speculation.

15)Governments will ban it if it gets too big , and they have a big incentive to do so , not only for the obscure usecases but also because it threatens the stability of sovereign currencies. Trump could kill bitcoin with one tweet , force fiat exchanges to cease activity.

16)Most cryptos are scams , the rest are just crazy speculative casino investments.

17)It is pyramidal : early adopters intend to profit massively while last comers get crushed. That's not how money works. The overwhelming majority of crypto holders are buying it because they think they will be able to sell it to a higher price later. Money is supposed to be rather stable. That's why the best cryptocurrencies are USDT USDC etc..

18)The very few stores accepting bitcoin always have the real price in the local currency , not in bitcoin. And prices like 0.00456329 BTC are ridiculous !

19)About famous brokers listing bitcoin : they have to meet the demand in order to make money , it doesn't mean they approve it , some even short it (see interactive broker's CEO opinion on bitcoin)

20)People say cash is backed by nothing and losing value slowly , and yes it is very flawed , but there is a whole nation behind it , it's accepted everywhere , you can buy more things with it.

21)Everybody in crypto thinks that there will be a new bullrun and that then , they will sell. But because everybody thinks it will happen , it might not happen. The truth is past performance doesn’t indicate future performance and it is absolutely not guaranteed that there will ever be another bullrun. The markets are unpredictable.

22)Also BTC went from about $0.003 to the price it is today , so don’t think it’s cheap now.

23)There is no recourse if you’re scammed/hacked/made a mistake in the address etc. No chargebacks. But it might be possible to do a rollback (blockchain reorganization) to reverse some transactions. BSV did it.

24)In case of a financial crisis , the speculative assets would crash the most and bitcoin is far from being a non speculative safe heaven ; and governments might ban it to prevent fiat inflation to worsen.

25) Having to write down the private key somewhere or memorize it is a security flaw ! It’s insane to think a system like this will gain mass adoption.

26) The argument saying governments can not ban it because it is decentralized (like they banned drugs) doesn’t work for cryptos. First , drugs are much harder to find and much more expensive and unsafe because of the ban , and people are willing to take the risk because they like it. But if crypto is banned , value will drop too much , and if you can’t sell it for fiat without risking jail , goodluck to find a buyer. Fiat exchanges could close. Banks could terminate every crypto related bank account. And maybe then the mining death spiral would happen and kill all cryptos.

27) Crypto doesn’t exist. It’s like buying air. It’s just virtual collectibles generated by a code. Faguzzi, fugazzi, it’s a whazzie, it’s a whoozie.. it’s a.. fairy dust. It doesn’t exist. It’s never landed. It’s no matter, it’s not on the elemental chart. It… it’s not fucking real!

28) Most brilliant guys have come out and said Bitcoin was a scam or worthless. Including Bill Gates , Warren Buffet , The Wolf Of Wall Street…

29) Inflation is necessary for POW , BTC code will have to be changed to bypass the 21M cap or mining will die ! If BTC code is not changed to allow for miners to be paid reasonably , they will cease mining when the bitcoin block reward gets too low.Even monero understood it ,the code will have to be changed to allow for an infinite bitcoin supply (devaluating all current bitcoins) or the hash will decrease and the security of bitcoin will decrease dramatically and be 51% attacked

30) Don’t mix up blockchain and cryptos. Even blockchain is overrated. But when you hear this or that company is going blockchain , it doesn’t mean they support cryptocurrencies.

31) Craig Wright had a bitcoin mining company with Dave Kleinman (he died) and on january 1 2020 he claims he will be able to access the 1.1M BTC/BCH/BTG from the mining trust. He may or may not dump them on the market , he also said BTC had a fatal flaw and that by 2019 there will be no more BTC.

32) Hacks in cryptos are very common and usually massive. Billions of dollars in crypto have been stolen in the last 6 years. In may 2019 Binance was hacked and lost 7,000 BTC (and it’s far from being the biggest crypto hack).

33) Bitcoin was first. It's an ancient technology. Newer blockchains have privacy, smart contracts, distributed apps and more.Bitcoin is our future? Was the Model T the future of the automobile? (John Mc Afee)

34) IOTA investiguating stolen funds on mainnet. IOTA shuts down the whole network to deal with trinity wallet attack.

35) Compared to bitcoin other cryptos work just as fine and don't waste so much energy.

36 ) Everytime miners disagree on the updates it will create another version of bitcoin : problem of governance and legitimacy.

37) Cryptos are only legitimate if they act as a credit for a redeemable asset like USDT or gold backed coins.


While the native language of the writter is not english , I think you get the point and it doesn't make it any less relevant.

On June 3, Binance Sis talked with Sun Ming, Partner and General Counsel of Distributed Capital-”Sun Ming, Partner of Distributed Capital: The past of the currency circle of a lawyer.” Sun Ming is more optimistic about Ethereum than Bitcoin. Sun Ming believes that the easiest way to invest is to choose the most important project in the main track.

On June 4, Charles Hoskinson, the founder of Cointelegraph Chinese and the Cardano project, gave a live broadcast and shared an in-depth discussion around the topic of “How to Cardano surpass Ethereum after five years of precipitation.” Charles Hoskinson, who was a close working partner with V God and BM, why did he leave Bitshares and Ethereum to create the Cardano project? There is an answer in the live room.

On June 4, Binance Li Jiayi talked with Ontology founder Li Jun-”Ontology founder’s blockchain entrepreneurial experience”. For the future of the public chain, Li Jun believes that in the past two years of infrastructure construction, the public chain has paid more attention to technology. However, in the process of open source in the blockchain industry, technical homogeneity is gradually emerging. In the next stage, the public chain will pay more attention to the application of landing entities and offline scenarios, and new focus will appear, which is a good thing for the development of the public chain.

On June 5, Binance Seven Seven talked to Binance Captains-Hard Candy, He Rensi, Deer Deer Captain, and three post-90s Binance Captains.

Ferrum Network Community Update — December 8, 2019

Dear Community,
What an exciting and jammed pack few weeks it has been — with the launch of staking, the 2Key Network partnership, and a major Kudi update — to name a few!
But as the profile of Ferrum continues to grow, it is essential we never stray from the fundamentals that got us this far: hard work, transparency, and a commitment to community.
In this community update, we provide a recap of the last few weeks, and look ahead to a few initiatives we are planning.
Business Update
With the release of the FRM Flexible Staking platform, we took that opportunity to kick the marketing into high gear. These marketing efforts paid off, and we were fortunate to be picked up by top influencers like Teh Moonwalker, Oddgems, and Micro Cap Gems. Here’s what happened the past few weeks.
Tech Update
For those who missed the Tech Update from our CEO Naiem Yeganeh, PhD, here are some highlights:
First Kudi Update
The First Kudi team on the ground in Nigeria continues to make significant progress.
What’s Next
It is critical we capitalize on the attention we have garnered from the team and community efforts, and to start 2020 with a bang. Here are some of the upcoming initiatives we are working on.
Flexible ERC-20 Staking v0.2
We are strongly considering launching another round of staking. We are taking the lessons learned from the first round and improving the experience. Community feedback will be key to make version two even better, so expect to see a series of polls in the coming days.
A Trading Community
A strong group of FRM traders who post technical analysis on social media is great for exposure and great for liquidity. We are currently laying the groundwork to build a trading community to come up with initiatives like trading competitions and special trading rewards. Anyone interested in joining such a community should PM Ian on Telegram.
FRM on Kudi
We have been working hard to add FRM and ETH to the Kudi app so our users can buy it directly with Naira. This will also open up additional utilities for the FRM token, including a premium membership program that will reward users for holding the token and using the app. More details to follow.
Expansion into other Markets
As you may know, one part of our business model is to partner with top notch teams in emerging markets where our fiat gateway + payments app technology can be successful.
We are happy to report that we have started to work with such a team in Brazil and they are in the early stages of launching their own product powered by Ferrum Network. More news to follow.
Conclusion
Thank you all for your continued support of Ferrum Network. 2019 was a really special year that we will never forget. But together we can make 2020 even better!
Very truly yours,
The Ferrum Network Team

What are Nano's biggest issues? Let's talk about it!

Let's talk about some of Nano's biggest issues. I also made a video about this topic, available here: https://youtu.be/d9yb9ifurbg.
00:12 Spam
Issues
Potential Mitigations & Outstanding Issues
01:58 Privacy
Issues
  • Nano has no privacy. It is pseudonymous (like Bitcoin), not anonymous.
Potential Mitigations & Outstanding Issues & Outstanding Issues*
  • Second layer solutions like mixers can help, but some argue that isn't enough privacy.
  • The current protocol design + the computational overhead of privacy does not allow Nano to implement first layer privacy without compromising it's other features (fast, feeless, and scalable transactions).
02:56 Decentralization
Issues
  • Nano is currently not as decentralized as it could be. ~25% of the voting weight is held by Binance.
  • Users must choose representatives, and users don't always choose the best ones (or never choose).
Potential Mitigations & Outstanding Issues
  • Currently 4 unrelated parties (who all have a verifiable interest in keeping the network running) would have to work together to attack the network
  • Unlike Bitcoin, there is no mining or fees in Nano. This means that there is not a strong incentive for emergent centralization from profit maximization and economies of scale. We've seen this firsthand, as Nano's decentralization has increased over time.
  • Nano representative percentages are not that far off from Bitcoin mining pool percentages.
  • In Nano, voting weight can be remotely re-delegated to anyone at any time. This differs from Bitcoin, where consensus is controlled by miners and requires significant hardware investment.
  • The cost of a 51% attack scales with the market cap of Nano.
06:49 Marketing & adoption
Issues
  • The best technology doesn't always win. If no one knows about or uses Nano, it will die.
Potential Mitigations & Outstanding Issues
  • I would argue that the best technology typically does win, but it needs to be best in every way (price, speed, accessbility, etc). Nano is currently in a good place if you agree with that argument.
  • Bitcoin started small, and didn't spend money on marketing. It takes time to build a community.
  • The developers have said they will market more once the protocol is where they want it to be (v20 or v21?).
  • Community marketing initiatives have started to form organically (e.g. Twitter campaigns, YouTube ads, etc).
  • Marketing and adoption is a very difficult problem to solve, especially when you don't have first mover advantage or consistent cashflow.
08:07 Small developer fund
Issues
  • The developer fund only has 3 million NANO left (~$4MM), what happens after that?
Potential Mitigations & Outstanding Issues
  • The goal for Nano is to be an Internet RFC like TCP/IP or SMTP - development naturally slows down when the protocol is in a good place.
  • Nano development is completely open source, so anyone can participate. Multiple developers are now familiar with the Nano protocol.
  • Businesses and whales that benefit from Nano (exchanges, remittances, merchant services, etc) are incentivized to keep the protocol developed and running.
  • The developer fund was only ~5% of the supply - compare that to some of the other major cryptocurrencies.
10:08 Node incentives
Issues
  • There are no transaction fees, why would people run nodes to keep the network running?
Potential Mitigations & Outstanding Issues
  • The cost of consensus is so low in Nano that the benefits of the network itself are the incentive: decentralized money with 0 transaction fees that can be sent anywhere in the world nearly instantly.
  • Paying $50-$100 a month for a high-end node is a lot cheaper for merchants than paying 1-3% in total sales.
  • Businesses and whales that benefit from Nano (exchanges, remittances, merchant services, etc) are incentivized to keep the protocol developed and running.
11:58 No smart contracts
Issues
  • Nano doesn't support smart contracts.
Potential Mitigations & Outstanding Issues
  • Nano's sole goal is to be the most efficient peer-to-peer value transfer protocol possible. Adding smart contracts makes keeping Nano feeless, fast, and decentralized much more difficult.
  • Other solutions (e.g. Ethereum) exist for creating and enforcing smart contracts.
  • Code can still interact with Nano, but not on the first layer in a decentralized matter.
  • Real world smart contract adoption and usage is pretty limited at the moment, but that might not always be the case.
13:20 Price stability
Issues
  • Why would anyone accept or spend Nano if the price fluctuates so much?
  • Why wouldn't people just use a stablecoin version of Nano for sending and receiving money?
Potential Mitigations & Outstanding Issues
  • With good fiat gateways (stable, low fees, etc), you can always buy back the fiat equivalent of what you've spent.
  • The hope is that with enough adoption, people and businesses will eventually skip the fiat conversion and use Nano directly.
  • Because Nano is so fast, volatility is less of an issue. Transactions are confirmed in <10 seconds, and prices change less in that timeframe (vs 10 minutes to hours for Bitcoin).
  • Stablecoins reintroduce trust. Stable against what? Who controls the supply, and how do you get people to adopt them? What happens if the assets they're stable against fail? Nano is pure supply and demand.
  • With worldwide adoption, the market capitalization of Nano would be in the trillions. If that happens, even millions of dollars won't move the price significantly.
15:06 Deflation
Issues
  • Nano's current supply == max supply. Why would people spend Nano today if it could be worth more tomorrow?
  • What happens to principal representatives and voting weight as private keys are lost? How do you know keys are lost?
Potential Mitigations & Outstanding Issues
  • Nano is extremely divisible. 1 NANO is 1030 raw. Since there are no transaction fees, smaller and smaller amounts of Nano could be used to transact, even if the market cap reaches trillions.
  • People will always buy things they need (food, housing, etc).
  • I'm not sure what the plan is to adjust for lost keys. Probably requires more discussion.
Long-term Scalability
Issue
  • Current node software and hardware cannot handle thousands of TPS (low-end nodes fall behind at even 50 TPS).
  • The more representatives that exist, the more vote traffic is required (network bandwidth).
  • Low-end nodes currently slow down the network significantly. Principal representatives waste their resources constantly bootstrapping these weak nodes during network saturation.
Potential Mitigations & Outstanding Issues
  • Even as is, Nano can comfortably handle 50 TPS average - which is roughly the amount of transactions per day PayPal was doing in 2011 with nearly 100 million users.
  • Network bandwidth increases 50% a year.
  • There are some discussions of prioritizing bootstrapping by vote weight to limit the impact of weak nodes.
  • Since Nano uses an account balance system, pruning could drastically reduce storage requirements. You only need current state to keep the network running, not the full transaction history.
  • In the future, vote stapling could drastically reduce bandwidth usage by collecting all representative signatures up front and then only sharing that single aggregate signature.
  • Nano has no artificial protocol-based limits (e.g. block sizes or block times). It scales with hardware.

Technical: A Brief History of Payment Channels: from Satoshi to Lightning Network

Who cares about political tweets from some random country's president when payment channels are a much more interesting and are actually capable of carrying value?
So let's have a short history of various payment channel techs!

Generation 0: Satoshi's Broken nSequence Channels

Because Satoshi's Vision included payment channels, except his implementation sucked so hard we had to go fix it and added RBF as a by-product.
Originally, the plan for nSequence was that mempools would replace any transaction spending certain inputs with another transaction spending the same inputs, but only if the nSequence field of the replacement was larger.
Since 0xFFFFFFFF was the highest value that nSequence could get, this would mark a transaction as "final" and not replaceable on the mempool anymore.
In fact, this "nSequence channel" I will describe is the reason why we have this weird rule about nLockTime and nSequence. nLockTime actually only works if nSequence is not 0xFFFFFFFF i.e. final. If nSequence is 0xFFFFFFFF then nLockTime is ignored, because this if the "final" version of the transaction.
So what you'd do would be something like this:
  1. You go to a bar and promise the bartender to pay by the time the bar closes. Because this is the Bitcoin universe, time is measured in blockheight, so the closing time of the bar is indicated as some future blockheight.
  2. For your first drink, you'd make a transaction paying to the bartender for that drink, paying from some coins you have. The transaction has an nLockTime equal to the closing time of the bar, and a starting nSequence of 0. You hand over the transaction and the bartender hands you your drink.
  3. For your succeeding drink, you'd remake the same transaction, adding the payment for that drink to the transaction output that goes to the bartender (so that output keeps getting larger, by the amount of payment), and having an nSequence that is one higher than the previous one.
  4. Eventually you have to stop drinking. It comes down to one of two possibilities:
    • You drink until the bar closes. Since it is now the nLockTime indicated in the transaction, the bartender is able to broadcast the latest transaction and tells the bouncers to kick you out of the bar.
    • You wisely consider the state of your liver. So you re-sign the last transaction with a "final" nSequence of 0xFFFFFFFF i.e. the maximum possible value it can have. This allows the bartender to get his or her funds immediately (nLockTime is ignored if nSequence is 0xFFFFFFFF), so he or she tells the bouncers to let you out of the bar.
Now that of course is a payment channel. Individual payments (purchases of alcohol, so I guess buying coffee is not in scope for payment channels). Closing is done by creating a "final" transaction that is the sum of the individual payments. Sure there's no routing and channels are unidirectional and channels have a maximum lifetime but give Satoshi a break, he was also busy inventing Bitcoin at the time.
Now if you noticed I called this kind of payment channel "broken". This is because the mempool rules are not consensus rules, and cannot be validated (nothing about the mempool can be validated onchain: I sigh every time somebody proposes "let's make block size dependent on mempool size", mempool state cannot be validated by onchain data). Fullnodes can't see all of the transactions you signed, and then validate that the final one with the maximum nSequence is the one that actually is used onchain. So you can do the below:
  1. Become friends with Jihan Wu, because he owns >51% of the mining hashrate (he totally reorged Bitcoin to reverse the Binance hack right?).
  2. Slip Jihan Wu some of the more interesting drinks you're ordering as an incentive to cooperate with you. So say you end up ordering 100 drinks, you split it with Jihan Wu and give him 50 of the drinks.
  3. When the bar closes, Jihan Wu quickly calls his mining rig and tells them to mine the version of your transaction with nSequence 0. You know, that first one where you pay for only one drink.
  4. Because fullnodes cannot validate nSequence, they'll accept even the nSequence=0 version and confirm it, immutably adding you paying for a single alcoholic drink to the blockchain.
  5. The bartender, pissed at being cheated, takes out a shotgun from under the bar and shoots at you and Jihan Wu.
  6. Jihan Wu uses his mystical chi powers (actually the combined exhaust from all of his mining rigs) to slow down the shotgun pellets, making them hit you as softly as petals drifting in the wind.
  7. The bartender mutters some words, clothes ripping apart as he or she (hard to believe it could be a she but hey) turns into a bear, ready to maul you for cheating him or her of the payment for all the 100 drinks you ordered from him or her.
  8. Steely-eyed, you stand in front of the bartender-turned-bear, daring him to touch you. You've watched Revenant, you know Leonardo di Caprio could survive a bear mauling, and if some posh actor can survive that, you know you can too. You make a pose. "Drunken troll logic attack!"
  9. I think I got sidetracked here.
Lessons learned?

Spilman Channels

Incentive-compatible time-limited unidirectional channel; or, Satoshi's Vision, Fixed (if transaction malleability hadn't been a problem, that is).
Now, we know the bartender will turn into a bear and maul you if you try to cheat the payment channel, and now that we've revealed you're good friends with Jihan Wu, the bartender will no longer accept a payment channel scheme that lets one you cooperate with a miner to cheat the bartender.
Fortunately, Jeremy Spilman proposed a better way that would not let you cheat the bartender.
First, you and the bartender perform this ritual:
  1. You get some funds and create a transaction that pays to a 2-of-2 multisig between you and the bartender. You don't broadcast this yet: you just sign it and get its txid.
  2. You create another transaction that spends the above transaction. This transaction (the "backoff") has an nLockTime equal to the closing time of the bar, plus one block. You sign it and give this backoff transaction (but not the above transaction) to the bartender.
  3. The bartender signs the backoff and gives it back to you. It is now valid since it's spending a 2-of-2 of you and the bartender, and both of you have signed the backoff transaction.
  4. Now you broadcast the first transaction onchain. You and the bartender wait for it to be deeply confirmed, then you can start ordering.
The above is probably vaguely familiar to LN users. It's the funding process of payment channels! The first transaction, the one that pays to a 2-of-2 multisig, is the funding transaction that backs the payment channel funds.
So now you start ordering in this way:
  1. For your first drink, you create a transaction spending the funding transaction output and sending the price of the drink to the bartender, with the rest returning to you.
  2. You sign the transaction and pass it to the bartender, who serves your first drink.
  3. For your succeeding drinks, you recreate the same transaction, adding the price of the new drink to the sum that goes to the bartender and reducing the money returned to you. You sign the transaction and give it to the bartender, who serves you your next drink.
  4. At the end:
    • If the bar closing time is reached, the bartender signs the latest transaction, completing the needed 2-of-2 signatures and broadcasting this to the Bitcoin network. Since the backoff transaction is the closing time + 1, it can't get used at closing time.
    • If you decide you want to leave early because your liver is crying, you just tell the bartender to go ahead and close the channel (which the bartender can do at any time by just signing and broadcasting the latest transaction: the bartender won't do that because he or she is hoping you'll stay and drink more).
    • If you ended up just hanging around the bar and never ordering, then at closing time + 1 you broadcast the backoff transaction and get your funds back in full.
Now, even if you pass 50 drinks to Jihan Wu, you can't give him the first transaction (the one which pays for only one drink) and ask him to mine it: it's spending a 2-of-2 and the copy you have only contains your own signature. You need the bartender's signature to make it valid, but he or she sure as hell isn't going to cooperate in something that would lose him or her money, so a signature from the bartender validating old state where he or she gets paid less isn't going to happen.
So, problem solved, right? Right? Okay, let's try it. So you get your funds, put them in a funding tx, get the backoff tx, confirm the funding tx...
Once the funding transaction confirms deeply, the bartender laughs uproariously. He or she summons the bouncers, who surround you menacingly.
"I'm refusing service to you," the bartender says.
"Fine," you say. "I was leaving anyway;" You smirk. "I'll get back my money with the backoff transaction, and posting about your poor service on reddit so you get negative karma, so there!"
"Not so fast," the bartender says. His or her voice chills your bones. It looks like your exploitation of the Satoshi nSequence payment channel is still fresh in his or her mind. "Look at the txid of the funding transaction that got confirmed."
"What about it?" you ask nonchalantly, as you flip open your desktop computer and open a reputable blockchain explorer.
What you see shocks you.
"What the --- the txid is different! You--- you changed my signature?? But how? I put the only copy of my private key in a sealed envelope in a cast-iron box inside a safe buried in the Gobi desert protected by a clan of nomads who have dedicated their lives and their childrens' lives to keeping my private key safe in perpetuity!"
"Didn't you know?" the bartender asks. "The components of the signature are just very large numbers. The sign of one of the signature components can be changed, from positive to negative, or negative to positive, and the signature will remain valid. Anyone can do that, even if they don't know the private key. But because Bitcoin includes the signatures in the transaction when it's generating the txid, this little change also changes the txid." He or she chuckles. "They say they'll fix it by separating the signatures from the transaction body. They're saying that these kinds of signature malleability won't affect transaction ids anymore after they do this, but I bet I can get my good friend Jihan Wu to delay this 'SepSig' plan for a good while yet. Friendly guy, this Jihan Wu, it turns out all I had to do was slip him 51 drinks and he was willing to mine a tx with the signature signs flipped." His or her grin widens. "I'm afraid your backoff transaction won't work anymore, since it spends a txid that is not existent and will never be confirmed. So here's the deal. You pay me 99% of the funds in the funding transaction, in exchange for me signing the transaction that spends with the txid that you see onchain. Refuse, and you lose 100% of the funds and every other HODLer, including me, benefits from the reduction in coin supply. Accept, and you get to keep 1%. I lose nothing if you refuse, so I won't care if you do, but consider the difference of getting zilch vs. getting 1% of your funds." His or her eyes glow. "GENUFLECT RIGHT NOW."
Lesson learned?

CLTV-protected Spilman Channels

Using CLTV for the backoff branch.
This variation is simply Spilman channels, but with the backoff transaction replaced with a backoff branch in the SCRIPT you pay to. It only became possible after OP_CHECKLOCKTIMEVERIFY (CLTV) was enabled in 2015.
Now as we saw in the Spilman Channels discussion, transaction malleability means that any pre-signed offchain transaction can easily be invalidated by flipping the sign of the signature of the funding transaction while the funding transaction is not yet confirmed.
This can be avoided by simply putting any special requirements into an explicit branch of the Bitcoin SCRIPT. Now, the backoff branch is supposed to create a maximum lifetime for the payment channel, and prior to the introduction of OP_CHECKLOCKTIMEVERIFY this could only be done by having a pre-signed nLockTime transaction.
With CLTV, however, we can now make the branches explicit in the SCRIPT that the funding transaction pays to.
Instead of paying to a 2-of-2 in order to set up the funding transaction, you pay to a SCRIPT which is basically "2-of-2, OR this singlesig after a specified lock time".
With this, there is no backoff transaction that is pre-signed and which refers to a specific txid. Instead, you can create the backoff transaction later, using whatever txid the funding transaction ends up being confirmed under. Since the funding transaction is immutable once confirmed, it is no longer possible to change the txid afterwards.

Todd Micropayment Networks

The old hub-spoke model (that isn't how LN today actually works).
One of the more direct predecessors of the Lightning Network was the hub-spoke model discussed by Peter Todd. In this model, instead of payers directly having channels to payees, payers and payees connect to a central hub server. This allows any payer to pay any payee, using the same channel for every payee on the hub. Similarly, this allows any payee to receive from any payer, using the same channel.
Remember from the above Spilman example? When you open a channel to the bartender, you have to wait around for the funding tx to confirm. This will take an hour at best. Now consider that you have to make channels for everyone you want to pay to. That's not very scalable.
So the Todd hub-spoke model has a central "clearing house" that transport money from payers to payees. The "Moonbeam" project takes this model. Of course, this reveals to the hub who the payer and payee are, and thus the hub can potentially censor transactions. Generally, though, it was considered that a hub would more efficiently censor by just not maintaining a channel with the payer or payee that it wants to censor (since the money it owned in the channel would just be locked uselessly if the hub won't process payments to/from the censored user).
In any case, the ability of the central hub to monitor payments means that it can surveill the payer and payee, and then sell this private transactional data to third parties. This loss of privacy would be intolerable today.
Peter Todd also proposed that there might be multiple hubs that could transport funds to each other on behalf of their users, providing somewhat better privacy.
Another point of note is that at the time such networks were proposed, only unidirectional (Spilman) channels were available. Thus, while one could be a payer, or payee, you would have to use separate channels for your income versus for your spending. Worse, if you wanted to transfer money from your income channel to your spending channel, you had to close both and reshuffle the money between them, both onchain activities.

Poon-Dryja Lightning Network

Bidirectional two-participant channels.
The Poon-Dryja channel mechanism has two important properties:
Both the original Satoshi and the two Spilman variants are unidirectional: there is a payer and a payee, and if the payee wants to do a refund, or wants to pay for a different service or product the payer is providing, then they can't use the same unidirectional channel.
The Poon-Dryjam mechanism allows channels, however, to be bidirectional instead: you are not a payer or a payee on the channel, you can receive or send at any time as long as both you and the channel counterparty are online.
Further, unlike either of the Spilman variants, there is no time limit for the lifetime of a channel. Instead, you can keep the channel open for as long as you want.
Both properties, together, form a very powerful scaling property that I believe most people have not appreciated. With unidirectional channels, as mentioned before, if you both earn and spend over the same network of payment channels, you would have separate channels for earning and spending. You would then need to perform onchain operations to "reverse" the directions of your channels periodically. Secondly, since Spilman channels have a fixed lifetime, even if you never used either channel, you would have to periodically "refresh" it by closing it and reopening.
With bidirectional, indefinite-lifetime channels, you may instead open some channels when you first begin managing your own money, then close them only after your lawyers have executed your last will and testament on how the money in your channels get divided up to your heirs: that's just two onchain transactions in your entire lifetime. That is the potentially very powerful scaling property that bidirectional, indefinite-lifetime channels allow.
I won't discuss the transaction structure needed for Poon-Dryja bidirectional channels --- it's complicated and you can easily get explanations with cute graphics elsewhere.
There is a weakness of Poon-Dryja that people tend to gloss over (because it was fixed very well by RustyReddit):
Another thing I want to emphasize is that while the Lightning Network paper and many of the earlier presentations developed from the old Peter Todd hub-and-spoke model, the modern Lightning Network takes the logical conclusion of removing a strict separation between "hubs" and "spokes". Any node on the Lightning Network can very well work as a hub for any other node. Thus, while you might operate as "mostly a payer", "mostly a forwarding node", "mostly a payee", you still end up being at least partially a forwarding node ("hub") on the network, at least part of the time. This greatly reduces the problems of privacy inherent in having only a few hub nodes: forwarding nodes cannot get significantly useful data from the payments passing through them, because the distance between the payer and the payee can be so large that it would be likely that the ultimate payer and the ultimate payee could be anyone on the Lightning Network.
Lessons learned?

Future

After LN, there's also the Decker-Wattenhofer Duplex Micropayment Channels (DMC). This post is long enough as-is, LOL. But for now, it uses a novel "decrementing nSequence channel", using the new relative-timelock semantics of nSequence (not the broken one originally by Satoshi). It actually uses multiple such "decrementing nSequence" constructs, terminating in a pair of Spilman channels, one in both directions (thus "duplex"). Maybe I'll discuss it some other time.
The realization that channel constructions could actually hold more channel constructions inside them (the way the Decker-Wattenhofer puts a pair of Spilman channels inside a series of "decrementing nSequence channels") lead to the further thought behind Burchert-Decker-Wattenhofer channel factories. Basically, you could host multiple two-participant channel constructs inside a larger multiparticipant "channel" construct (i.e. host multiple channels inside a factory).
Further, we have the Decker-Russell-Osuntokun or "eltoo" construction. I'd argue that this is "nSequence done right". I'll write more about this later, because this post is long enough.

Huobi Derivative Market (Huobi DM)
Margin Trading
Huobi Global launched Huobi Derivative Market (Huobi DM) exchange to selected countries. It provides margin trading, with very low daily loan interest rates of 0.1%. Margin Trading allows users to increase their investment exposure given a limited base principal to enjoy multiple returns.
3-Steps taken in Margin Trading:
  1. Request for Loan
  2. Trade on Margin (Long/Short)
  3. Repay Margin Loan and Interest
With the introduction of Cross Margin on Huobi, users will have to explicitly input the respective margin type before executing the above 3 steps. Balances on the Cross Margin balance does not show on the Isolated Margin balance.
Huobi Futures
Huobi Futures is a kind of digital currency derivatives. Users can make a profit from the rising/falling of digital currencies prices by going long or selling short based on their own judgment.
The Huobi Futures Contract adopts spread delivery. When the contract expires, all open positions will be closed at the index-based last-hour arithmetic average price, instead of physical delivery.
BTC/ETH/EOS/LTC/XRP/BCH/TRX/BSV/ETC Contracts are available on Huobi DM. Contracts are priced in USD, with corresponding digital currency (BTC/ETH/EOS/LTC/XRP/BCH/TRX respectively) as margin to open positions, and PnL is also settled in corresponding digital currency.
Weekly, bi-weekly and quarterly contracts are available in Huobi DM. Weekly contracts will be settled on imminent Friday; Bi-weekly contracts will be settled on next Friday; Quarterly contracts will be settled on the last Friday of March, June, September and December.
Choices of leverage: 1x, 5x, 10x, 20x
Huobi Perpetual Swap
Huobi introduced Perpetual Swaps on March 27, 2020 (GMT+8). Huobi Perpetual swap is a kind of digital currency derivatives. Users can make a profit from the rising/falling of digital currencies prices by going long or selling short based on their own judgment. Similar to a margin spot market, its price is close to the price of the underlying reference index. The main mechanism for anchoring spot prices is the cost of funds. Perpetual swap have no delivery date. Users can always hold it. Perpetual swap are settled every 8 hours. After each settlement, the realized profit/loss and unrealized profits/losses are transferred to the user account balance.
Partial Liquidation
Huobi Futures adopted partial liquidation to help position holders reduce liquidation risk. Users with large positions and high leverage bear high risk. Huobi Futures releases partial liquidation with the aim to lower possible losses due to high price volatility thus giving users better trading experience.
Under partial liquidation mechanism, when liquidation is triggered, instead of liquidating all positions at once, the system reduces positions gradually till a grade whose margin ratio is great than 0. Full liquidation will only occur when the margin ratio of tier 1 upper limit net position still fails to be great than 0.
Trading Fees
The Huobi exchange has a fair trading fee structure. Every asset traded via Huobi Global is subject to a 0.2% trade fee, for both market makers and takers. Further, Huobi Global has introduced a tiered fee system which offers competitively lower fees for high volume traders. VIP membership gives access to various fee reductions and other benefits.
Huobi Prime
Huobi Prime, the Launchpad platform which we can call Direct Premium Offering (DPO), does share some similarities with initial exchange offerings (IEO) like Binance Launchpad, but it is unique as it is not a fundraising platform, and any coins purchased on the platform are immediately deposited into the users’ wallets and tradable on Huobi Global. Huobi Prime offers its users early access to the coins of premium projects, which can be bought using its native crypto currency, the Huobi Token. To avoid dumping, Huobi has implemented an innovative idea of a period of tiered price limits.
Huobi FastTrack

What I like the most about Huobi
  1. An established platform that’s been operating since 2013, which is a long time in the crypto world.
  2. Highly secured with decentralized exchange structure, which helps to resist DDOS attacks. Huobi has never suffered a large hack.
  3. Huobi Security Reserve of 20000 BTC to compensate users’ loss of funds.
  4. Dedicated, fast and 24/7 customer support.
  5. Regulated in major jurisdictions.
  6. User interface is very smooth and clean.
  7. Over 230 crypto assets are available.
  8. User education program is good initiative.
  9. Separate trading desk for institution and firm size users.
  10. Very transparent about its operations, listings and projects.
  11. Huobi Wallet is secured and very easy to operate.
  12. Huobi mobile app is smooth and very easy to use.
  13. Competitive fees.
  14. Has taken serious steps towards avoiding wash trading.
  15. Impressive array of trading pairs.
  16. Has given more important on community participation, like voting for listing, mining pool, Huobi Knights program etc.
  17. I like Huobi Prime because of following reasons: -
(a) Purchased tokens are immediately deposited into user’s accounts,
(b) As projects launch exclusively through Huobi Prime from day one, all users get assets at the best price.
(c) Tiered price limits on the platform protect both investors and projects from immediate dump.
  1. Huobi screen projects and launches which are only the best. I don’t have to worry about poor or scammy projects.
  2. Burning of HT is a great move and it would benefit long term holders.

AMA Recap of CEO and Co-founder of Chromia, Henrik Hjelte in the @binancenigeria Telegram group on 03/05/2020.

Moh (Binance Angel)🇳🇬,
Please join me to welcome, “CHROMIA CEO & Co-founder, Henrik Hjelte” and “ CMO, Serge lubkin”
Oh, before we proceed, kindly introduce yourselves and tell us a bit about your roles at Chromia u/sergelubkin & u/henrik_hjelte.
Henrik Hjelte,
Ok, I’m Henrik, I’m CEO of ChromaWay that crated the Chromia project. My background is a bit mixed: developer for 30+ years (since 80: s), but I studied other things at university (economics, politics, social sciences philosophy). Life is more than computer you know… I worked with FInance/IT then started a web startup and got to know Alex Mizrahi who worked as a developer….
Web startup didn’t fly, but Alex showed me bitcoin. When I finally read the whitepaper I was blown away, and joined Alex colored-coins project, the first open source protocol to issue tokens. in 2013.
So, we started with open-source tokens (that kickstarted the blockchain industry. Then started company together 2014.
That is a long intro, I’ll shut up now… Thanks….
Serge,
I’m Serge, I’m assisting Henrik today and I work with Chromia marketing team as well as on some business development projects
Moh (Binance Angel)🇳🇬, , Question No 1 :
Kindly describe the CHROMIA project and what it aims to achieve?
Henrik Hjelte,
Chromia is a new public blockchain based on the idea of integrating traditional databases, Relational databases with blockchain security. Chromia is a general purpose blockchain with full smart contract capabilities, just that it is a lot easier to code, even complex applications. You code with an easy to learn new programming language that combines the power of SQL and normal languages but makes it secure in a blockchain context. Up to 1/10 the code-lines vs other blockchains. There is a blog post about it, I’ll share later. On lines of code.
The aim of Chromia is to combine relational databases, which exist in every kind of organization, together using blockchains. We want to provide a platform for our users to develop totally decentralized apps securely. Our goal is for Chromia to be seen as the number one infrastructure for decentralized applications.
https://blog.chromia.com/reasons-for-rell-compactness/
Moh (Binance Angel)🇳🇬,Question No 2:
What inspired the CHROMIA Core team to pick interest in CHROMIA project? what breakthrough have you achieved so far? what are the present challenges you’re facing and how are you planning to overcome them?
Henrik Hjelte,
We started with public blockchains, tokens in 2012, the world’s first stable coin with a bank 2015 (LHV). When coding that solution, peer to peer payments of Euro-tokens, we discovered we need performance reasons to store all data in a database. We needed to quickly know the “balance” of a user, and can’t loop through a blockchain. And slowly the idea grew that we can make the database INTO a blockchain, integrate completely with the transaction mechanism of a database. So, we did it as a private blockchain first (Postchain), used it for some projects, then came up with the idea to make a Public Blockchain based on it.
The motivation is that we felt we needed a better programming model for blockchains. Our CTO Alex has always been thinking of optimal solutions for blockchain technology and has lots of experiences thinking about it. Also: make real-world useful things. For example, we support free-to-play models since users do not need to own “our” token to USE apps, the application itself (often the developer) pays for hosting. And of course, great performance. Also: more knowledge of who runs nodes and risk level. So, it is more suitable for enterprises.
In Chromia the application (at the start the developer) decides Who should be allowed to run its own blockchain (every dapp has its own blockchain). You can also say on a higher level that we want to provide technology to create “Public applications”, a tool
that enables us to create a fairer world.
https://blog.chromia.com/towards-publicly-hosted-applications/
Moh (Binance Angel)🇳🇬, Question No 3 :
Why did you create your own blockchain instead of leveraging on existing and proven base layer protocol?
Henrik Hjelte,
None of the existing protocols are suitable to support large-scale, mainstream applications. We designed Chromia to give our users exactly what they want; fast support, useful features, with an affordable service cost. Other platforms do not have the ability to host data applications in a decentralized and secure way, as Chromia can. Chromia also has its own bespoke programming language that sets it apart from SQL-based platforms. It’s so easy to use, even non-developers can understand it!
The other big difference with Chromia concerns payments. Chromia gives its users freedom from having to pay for each transaction. With Chromia, you have the flexibility to decide how to set fees for your dapp
And when it comes to “proven base layer protocols”: they are just a few years at max. Chromia is built on top of Postgresql, that has been used in enterprises for decades, a really proven technology. And the Java virtual machine on top of that. This is proven tech, at core.
Moh (Binance Angel)🇳🇬, Question No 4 :
What is Postchain?
Henrik Hjelte,
Postchain is an open-source product of ChromaWay for enterprise clients and it’s the core technology on which Chromia is built.
Postchain is a replicated blockchain and database that offers highly resilient distributed database management with distributed control.
Postchain is the only product on the market that combines the immutable consensus of a blockchain and the properties of a real database management system (You know, the tech that built SAP, Facebook, Banks…) …
Postchain allows you to share information between companies and/or individuals in a secure and transparent way.
That is the low-level base of Chromia you can say
Moh (Binance Angel)🇳🇬,
Can you please name some of your clients that are using this service already?
Serge,
You mean products built on Postchain? Also, Stockholm Green Digital Finance, Green Assets Wallet that’s now functioning on Chromia Bootstrap Mainnet.
Big financial institutions
It’s only a beginning of course, but very promising one. https://greenassetswallet.org/news/2019/12/12/launch-of-the-green-assets-wallet
Henrik Hjelte,
We got a lot of attention with the Swedish Land registry; we did a joint project between them and banks and a telco etc on postchain as base.
Then, right now we do a large project with the Inter-American Development bank also about land-registration (processes) in South America.
We had a client, Stockholm Green Digital Finance, that did a system for green bonds (tracking environmental impact. Yes, as Sege says, it was later moved to Chromia…
Which is cool. Also, another external development company did that phase of the project, proving that other can build on our tech,4irelabs from Ukraine is their name. Some companies using the GAW: Blackrock. SEB Bank etc…
Also, we have done more projects, in Australia, asia etc. Oh Daimler too (the Mercedes company) …
Moh (Binance Angel)🇳🇬,
Lots of enterprise clients you’ve got. No wonder I do see the meme “CHR=ETH KILLER”
Serge,
It’s a meme from our supporters. But we believe we can coexist:)
For some niche things eth is good :)
So, no killing :D
Henrik Hjelte,
We want to work with partners too for this, we can’t do all projects ourselves. Also, for Chromia projects, ChromaWay company can help do support maintenance etc. So, it is not competing, it adds value to the ecosystem.
Yeah ETH is good too, for some applications. We are friends with them from colored-coin times.
And colored-coins inspired ETH, and ETH inspires us.
Moh (Binance Angel)🇳🇬, Question No 5 :
Lastly, CHROMIA is already doing very well in terms of business. You just got listed on BINANCE JEX, you are on-boarding new clients and dishing out new features. But what’s next? Is there anything to be excited about?
Henrik Hjelte,
Plans for 2020 are to both release a series of dapps to showcase how fantastic Chromia is, as well as continue to develop the platform. And when it is secure and good enough, we will release the mainnet.
Dapps are now being made by us as well as others. We do a decentralized social network framework called Chromunity, now released to TestNet. It is really cool, users can vote over moderators, and in the future users might even govern the complete application, how it can be updated. This is a great showcase for Chromia and why we use the slogan Power to the Public.
https://testnet.chromunity.com/
Games coming are:
Mines of Dalarnia (by Workinman Interactive). An action game in a mine with blockchain rental of plots and stuff. Already on TestNet and you can take a peek on it at https://www.minesofdalarnia.com
more coming…
Krystopia 2, novas journey. A puzzle game done by Antler Interactive. Could only find trailer though: https://www.youtube.com/watch?v=-G95-Dw3kI4
However, we have even larger ambitions with blockchain gaming…
We are doing A secret demo-project that we do together with Antler to showcase the technical potential of Chromia platform.
Another exciting relase is an indie game Chain of Alliance, done by two external developers. It is a strategy game with full-logic on blockchain. Public release on TestNet on May 22!
More coming in 2020: Other dapps from other companies, one in impact-tech.
That is a serious app, Chromia also works outside gaming and social media for enterprises and startups
And I hope some of you will do something, we want to support dapps on the platform so reach out to us…
Moh (Binance Angel)🇳🇬,
When can we be expecting the mainnet? Any approximate time? I’m sure the community will really excited to have that info
Serge,
It’s now in Bootstap phase, so it’s technically already functioning. MVP will be very soon
Stay tuned;)
Twitter questions Vs answers
Ellkayy,
What’s the unique thing in Chromia that no other blockchain has, that makes you the better option?
Henrik Hjelte,
Unique: Chromia is the only blockchain that also has a real, proper database built-in. And blockchain is about managing data in a shared context. How to best managed data was solved in computer science already. So far, it is the relational algebra model that is used in 100% of all enterprises, and has an 85% market share. Chromia is the only blockchain that use that model and that power.
Ellkayy,
Why Chromia use RELL and not SQL or JavaScript? Can developers with other language knowledge use Chromia?
Serge,
Rell is the only language on the blockchain side. You can combine with anything on client-side, although now client only exists for JS/TS, C# and Java/Kotlin. Rell is a language for relational blockchain programming. It combines the following features:
1 Relational data modeling and queries similar to SQL. People familiar with SQL should feel at home once they learn the new syntax.
2 Normal programming constructs: variables, loops, functions, collections, etc.
3 Constructs which specifically target application backends and, in particular, blockchain-style programming including request routing, authorization, etc.
Rell aims to make programming as convenient and simple as possible. It minimizes boilerplate and repetition. At the same time, as a static type system it can detect and prevent many kinds of defects prior to run-time.
Roshan DV,
I have been monitoring your project for a while but some concerns about it: Your project will build your own core network, so you have more visibility than Ethereum and NEO. These are projects that were born before and which also have a very large community. And what can assure you that your project will guarantee the functionalities that you have defined?
Henrik Hjelte,
What came first? I want to remind that Vitalik was in the colored-coins project, led by our CTO and we had blockchain in production before ETH and NEO etc existed. We are the old dogs…
Large community: We are part of the same community. When developers are fustrated and want to try new tech, they go to us from other blockchains.
Also, we have a large potential: SQL (close to Rell and our tech) is the world top 3 language. Bigger than Java. Bigger than PHP. Only beaten bny HTML and javascript. Soliditiy is not on top 20 list. THere are millions of developers that know SQL. That is potential for community… (source is Stackoverflow annual programming survey).
Paul (Via Manage),
What are the utilities of Chromia and what purpose does the Chromia coin serve?
Serge,
Chromia meta-token called Chroma (CHR). It is used in Chromia to compensate block-producing nodes by fees. In Chromia, fees are paid by dapps, which can in their turn collect fees from users. Chromia provides mechanisms which balance the interests of developers and users. Dapp tokens can be automatically backed with Chroma, providing liquidity and value which is independent of investment into the dapp. Dapp investors can be compensated in Chroma through a profit-sharing contract. For developers, Chromia offers the opportunity to derive income from dapps. This incentivises the creation and maintenance of high quality dapps because better dapps generate more income and create more demand for tokens owned by the developer. The Chromia model is designed to support sustainable circular economies and foster a mutually beneficial relationship between developers, users, and investors.
Idemudia Isaac,
Thank you very much u/henrik_hjelte u/sergelubkin
You stated your plans for 2020 is to release series of dApps. What kind of large scale, mainstream decentralized application and $Chromia products do you think is suitable for the Nigerian environment?
Henrik Hjelte,
Actually, this is why we want to work with partners. We cannot know everything, For African market we have seen of course payments/remittances (but it has fallen out of trend). We would love to do real-estate /land-registration but we understand we need a strong local partner (more than a single person, a real company or organization driving).
●CC● | Elrond 🇵🇭,
What plans do you have to building a vibrant global community around Rell? And how would you go about encouraging/incentivising such ‘Rellists’ around the world to build dApps on Chromia? u/henrik_hjelte u/sergelubkin
Henrik Hjelte,
For developers (I am one too, or used to be) you normally need to prove a few things:
\ That the tech is productive (can I do apps faster?)*
\ That it is better (less bugs, more maintainable?)*
Then the community will come. We see that all the time. Look at web development. React.js came, and developers flooded to it. Not because of marketing on Superbowl, but because it was BETTER. Fewer bugs and easier to do complex webapps.
So, at core: people will come when we showcase the productivity gains, and that is what we need to focus on.
●CC● | Elrond 🇵🇭,
Why do you choose to build Chromia token on ERC20 instead of other blockchain such as BEP2, TRC20…or your own chain while ERC20 platform is very slow and have a case of fee? u/henrik_hjelte u/sergelubkin
Serge,
So far Ethereum has the best infrastructure, it’s the oldest and most reliable network for tokens. It also became the industry standard which exchanges utilize. We will transfer 80% of all erc20 tokens to our Chromia blockchain when it’s ready for that.
Koh,
In your whitepaper it says in the upcoming version of ChromiaWallet that it will be able to function as a Dapp browser for public use. Q) Will it be similar to the Dapp browser on Trust Wallet?
Serge,
It’s live already try it http://vault-testnet.chromia.com/
It’s the wallet and a dapp browser
CHROMIA is SOLID,
Your metamorphosis is a laudable one,surviving different FUD, how have you been able to survive this longest bear market and continue building and developing cos many projects have died out in this time period!
Henrik Hjelte,
You need to know we started a company before ETH existed. There was 0 money in blockchain when we started. I did it becuase it was fun, exciting tech and MAYBE someone would be interested in the thing we made “Tokens”…
We were never in the crazy bull-market, manly observed the crazies from the side. We fundraised for CHR in a dip (they called it bear market). ChromaWay the company also make money from enterprises.
Алекс,
What is SSO?
What makes it important for chromias ecosystem?
Why should we users be attracted to it?’
Serge,
Chromia SSO is perhaps the most important UX improvement that Chromia offers the decentralized world. It revolutionizes the way users interact with dapps. Any dapp requires users to sign transactions, that means they need a private key. Control of the private key is control of any and all dapps or assets associated with it. This means that private keys have an especially stringent set of security requirements in a blockchain context — they control real value, and there is no recourse if they are compromised or lost. https://blog.chromia.com/chromia-sso-the-whys-and-the-whats/
Olufemi Joel,
How do you see the Chromia project developing in 3 to 5 years, both on the commercial level and on the evolution of the company? What are the plans for expansion in different regions? Are you going to outsource the team/skills or keep it centralized and set up offices?
Henrik Hjelte,
I take part of the question. On outsource: we were a distributed team from day one, with co-founders from 3 countries (still living there). We are distributed now, Ukraine, Sweden, Vietnam, Croatia, China are “hubs” then we have individuals too. No big plan, just where we found great developers…
Park Lee, u/henrik_hjelte
You claim CHOROMIA have fast support, useful features with an affordable service cost. That fast and the fees are cheap but can you guarantee stability?
What’s the Algorithms which are used by CHROMIA for that fast? And Can you explain it?
Serge,
We use PBFT protocol with some features of DPOS, this plus sidechains parallelism offers almost unlimited speed and scalability. We also use the feature called anchoring to secure all transactions in batches on Bitcoin blockchain.
Mario Boy,
What are you guys trying to achieve as an end goal? The next Ethereum? Or the next enterprise version of Ethereum? Or something different?
Henrik Hjelte,
The end goal… good question. When we started in 2014 there were no other blockchain companies, so we wanted to do the best blockchain technology in order to enable a decentralized world with more fair applications. And that is what we still do. Technology/software that can enable people to make a fairer world
Erven James Sato,
“STAKING” is one of the STRATEGIES to ATTRACT USERS and ACHIEVE MASS ADOPTION
Does your GREAT PROJECT have plan about Staking?
Serge,
Yes, we announced our staking plans couple of months ago https://blog.chromia.com/on-providers-and-stakes/
We are working with our current partners to make it accessible for general public.
Chizoba,
I often see Chromia and ChromaWay being used interchangeably, what is the relationship between the two?
Henrik Hjelte,
ChromaWay the company started Chromia from code done as postchain. This is normal in open-source development, a company that leads development. But Chromia will be a decentalized network, so ChromaWay will not make direct money out of it more than if we have a role as a Provider (and get payed for hosting). ChromaWay can indirectly make money from optional support and maintenance etc. Also, this, perfectly normal in open-source world.
And it also benefits Chromia that there is a market for support.
A market open for competition.
No special treatment for “ChromaWay”
Enajite,
How to start coding on Chromia?
Henrik Hjelte,
Go to https://rell.chromia.com and follow the tutorial. Enjoy the free time you get compared to other blockchain languages…
●CC● | Elrond 🇵🇭,
Chromia process 500 TPS, these is slow compare to other Blockchains, where we can see now 60K TPS if more capacity require, how can that be? u/henrik_hjelte u/sergelubkin
Serge,
Yes, if you need faster speed you can use parallelism by having multiple blockchains for your dapp. Also, by optimization and better architecture sky is the limit.
Delphino.eth ⟠,
Can we consider Chromia an hybrid? For its mixing of Blockchain and a Database?
Henrik Hjelte,
Yes and no. I want to stress that Chromia is a FULL blockchain. It is not only “inspired”. It is a blockchain AND a database.
I tend to think about Hybrid more in the usecases that you might have as a customer. For example, a bank might want to have some data/transactions private (as a private blockchain) and have another half of the application with public data (on Chromia). So that is a hybrid solution, and Chromia ROCKS in that segment since it is the only blockchain that is complete relational database (what the normal world uses anyway for 85% of all applications)
Example area: “open banking”
Steve bush,
How will Chromia I have any empower Investors, Companies, Developers, Platform Users to
deliver impactful solutions and bring value to people all over the world?
Henrik Hjelte,
In order to make blockchain go big, we need to have users. Users need to be able to use apps with ease. Chromia have features like single-sign on (ease of use), but importantly do not require owning tokens to USE apps.
Also, it needs to be easy to make applications. For example, if you are a student in US and came up with an idea, you want to make an application for your school. Let’s call it “thefacebook”. You code something in PHP and MySQL. DID YOU SEE THAT. SQL. SQL.SQL. It is the same tech that Chromia has but no one else in the blockchain business. SQL rules the world if you look outside the crypto bubble. Google the Oracle head-office… 100% of all enterprises use it… Because it is easy and powerful.
And we even improve on SQL with Rell….
So, compare that with a hacky virtual machine that have a few years…. 😊
August,
“Mines of Dalarnia” is a game that has caught my attention a lot, due to its simplicity and quality. But in the time that I have used it I have not been able to differentiate between the Chromia blockchain of this game and that of the competition? What other games do you have next to develop? I would like to give ideas in those games like a Gamers!
Henrik Hjelte,
We thought about in corona time sports club might want to engage more with their fans digitally. And of course, E-Sports is getting a real momentum as the young generation grows up. Now a bit sad that all games are centralized. My daughter will be sad when (at some day?) they will close down roblox… it happens to all centralized apps eventually… that is what we fix. Power to the Public to control apps and their future. I’ll repost again Alex post. Sorry I like it a lot… https://blog.chromia.com/towards-publicly-hosted-applications/
Bisolar,
Good day Chromia team from a Chromia fan
Can you tell us Chromia’s geographical focus at the moment and the proces it follows for it BUSINESS DEVELOPMENT?
What factors do you consider before identifying NEW MARKETS to enter?
Serge,
Chromia will initially focus on community building in China, Korea, US and Europe. The focus of community growth will gradually expand to other markets as the project gains popularity.
Current community growth strategies of Chromia include:
Chromia blockchain incubator creation to welcome more projects to the Chromia blockchain
Host blockchain gaming conferences, workshops, and meetups to engage with potential users.
Provide online and face-to-face tutorials to engage with dapps developers.
Attract blockchain developers through direct and indirect approach via specialized platforms and communities.
Develop our relations with existing and previous corporate clients, and their partnership networks to participate in their blockchain ventures
Launch Node program to encourage system providers to run nodes on the Chromia blockchain.
Staking program for Chroma (CHR) tokens
Active community engagement via social channels.
Future community growth strategies of Chromia after Mainnet launch include:
Partner with more gaming studios, startups and enterprises
Build local communities with Ambassador Programs.
Partner with external incubator and accelerators to provide blockchain expertise and introduce projects to Chromia ecosystem
Continue organizing hackathons around the world to attract more developers.
Emmanuel,
I want to know the current structure of your roadmap? What is the future roadmap of CHROMIA? Is there any key milestone coming???
Henrik Hjelte,
It is easy to do a roadmap; anyone can make a pape plan. But I think they are used in the wrong way. Software is hard, blockchain is even harder because it NEEDS TO BE SECURE. No MVP releases. We cannot even have roadmap deadlines and skimp on quality. Where we are now though is: Rell language finished so much that developers can write apps and see its magic. We have external devs doing dapps. We have the first phase of mainnet. We have a series of releases coming up. We will release mainnet when it is secure enough, and gradual roll out. I think quite soon, development is going great at the moment, a bit quicker than we though.
Ellkayy,
Why doesn’t Chromia transactions use gas? How do you power transactions then?
Serge,
Main feature of gas in Ethereum is to pay for transactions for miners get rewards. In our scenario Providers get rewards from dapp owners. So dapp owner pays for storing their dapp. It’s like Amazon Web Service model. Then dapp owner can monetize it in its own way.
Ellkayy,
Many developers don’t know RELL, just Solidity and SQL. Is this a barrier or threat to Chromia? Why RELL is better?
Henrik Hjelte,
Very few developers know Solidity. Do a search on github. I referred previously to stackoverflow programming language survey results. https://insights.stackoverflow.com/survey/2019#technology
If you know SQL, you learn Rell in a day.
SQL is the top 3 language here. I’d say there are millions that can easily jump to Rell.
Soldity or other blockchains, not on top 20 list even.
Rell is a hipper, nicer version of SQL that is also a “normal” programming language.
Developers like to learn new things, new languages. Otherwise we would be stuck with PHP, the DOMINANT language. Well, is it still? Seems javascript and react.js and node etc is taking over…
