Usechain underlying system supports user identity, credit rating, and user privacy to exist harmoniously. It supports regulation, and user privacy as well.

There are four main developments of the mainnet beta which are:

1. Sub-account Feature
2. Optimized RPOW Algorithm
3. Complete Credit System
4. Optimized Wallet & Explorer

What is the Sub-account feature?

Usechain sub-account system is developed based on the Elliptic Curve Cryptography and AB account model. In a common blockchain system, a single user may have the need to do transactions using multiple accounts. You will find it convenient in Usechain system that, you can generate a random amount of sub-accounts from one main account, and the only private key you need to keep is the one corresponding to the main account.

In the alpha version, we knew that one user one main account and the main account on Usechain system should be the one get verified by doing KYC. it solves the problem of “equity “ from the point of identity authentication, thus you can vote with your main account( one account one vote) instead of voting with stakes which may lead to unfair.

Sub-accounts are anonymous. The possibility of exposing one’s identity will rise if using the main account heavily, though all the identity information on chain is invisible in general cases. Hence, the sub-account system is to meet a higher requirement of privacy. You can use sub-accounts in scenarios insensitive to identities, doing transactions, payments or in dapps.

What is the credit scoring system?

Credit scoring system and identity authentication complement each other, to build the Usechain identity system which not only supports centralized PKI (Public Key Infrastructure) but also supports decentralized distributed authentication.

There are four kinds of scores in the system: transaction score, authentication score, comment score, and reward & punishment score.

Transaction score is more independent and will be separated when calculating.

What’s new in RPOW?

1. Miner punishment mechanism. If a picked miner’s mining success rate is lower than 80% and lasts for a certain time, he will be unable to mine blocks within 24 hrs. If such punishment happens 3 times, then this miner will be removed permanently.
2. Miner online flag bit. You can turn off the flag bit when you are offline to avoid been punished.

Wallet & Explorer update

1. Wallet: At present, the android wallet app supports CA certification, you can register main account and sub-account here, search transactions and history and check your credit score. Download link: https://fir.im/wm3f?utm_source=fir&openId=oGB0Cj0yQJJ3A92xGBOpLlrD_Slc
2. Explorer: Apart from functions supported in the alpha version, the beta version newly added features as follows:

1)UI optimization. Added user credit scores and miner status display.

2)Rebuilt backend database and store the complete status data of Usechain network. Data includes the balance of addresses, transaction & authentication scores, block data, transaction data, miner data, and committee data.

3)Provided data access interfaces to wallet service, as well as to users.

◆ Usechain Live Stream: Exchanges Hotspot Tracking with former Huobi CSO◆

In the live stream column “Huining Cao and his blockchain friends” on April 26, Professor Cao invited Cai Kailong, who was the CSO of Huobi Group, to discuss the recent developments of exchanges from various areas.

Cai Kailong said in the live stream that he thinks in the world of crypto exchanges, the strong will get stronger while the weak get weaker, which is similar to the famous Mattew effect — the rich get richer and the poor get poorer. Besides, polarization is the future of crypto exchanges, he added.
In his opinion, some crypto exchanges like Coinbase will make great efforts in getting a license and improving compliance so that they can do business with big fishes in the traditional financial markets following a clearer regulation framework. Others who find it hard to get a license will stick to crypto-to-crypto trading.

Usechain development report in the last two weeks is all above. Thank you all for your support and trust!

Dear Usechain Community,

After over 15 months of development work, we are excited to announce that the Usechain mainnet alpha has now been launched.

To understand the Usechian network, you may visit the at https://github.com/usechain/doc/wiki/Quick-start-EN.

To check block information, you may visit the block explorer at http://mainnet.usechain.cn/#/.

Note: Since the Usechain mainnet is an alpha version, the tokens you get from Usechain faucet or from mining or from other ways are just for test. It has no real value at present!

Technology brings us together.

Usechain was born in late 2017. “I view blockchain as a way to create trust in transactions by strangers on line, it has huge ramifications for finance as finance is built on trust. I believe once the regulators can work out an efficient way to avoid abuses, It will be the future of finance. My startup of Usechain is to participate in this process, and I believe it will take about 20 years to be fruitful.” Usechain founder, Professor Huining Cao once said.

Today, even as we celebrate the launch of our mainnet alpha, we believe that this is just the start of the journey for us all. Looking beyond the launch, we will continue to add new features, enhance the platform, and further our research.

Mining On Usechain

Miner Incentive Mechanism

It cost 5~7 seconds to mine a block on Usechain network, for each block, the reward is 15 USE.

On average, there will be 14400*365=5,256,000 blocks to be mined each year. According to the block reward, a extra total of 78,840,000 USE will be issued each year.

Mining Equipment

Computer.

For miner registration and mining on Usechain mainnet alpha, please refer to https://github.com/usechain/doc/wiki/Miner-EN.

Token Swap

We’ve received multiple enquiries regarding the token swap. We are working with exchanges to support the token swap from ERC20 to native USE tokens, which is expected to commence from June 2019.

Please note that there is no action required from USE holders at the moment. We will release guidelines on how to swap your USE tokens to native USE tokens after the mainnet is stable.

Once all the steps to ensure network stability are finalized, we will make an additional official announcement.

Blockchain R&D Roadmap

Our blockchain research and development team is planning to work on the following areas after the mainnet alpha launch. These topics are non-exhaustive and subject to change along the way.

Once again, we would like to thank our community for your patience, and being on this journey with us. We choose to do Usechain, not because it is easy, but because it is hard.

Usechain Mainnet Alpha Launch & Beyond was originally published in Usechain on Medium, where people are continuing the conversation by highlighting and responding to this story.

Dear Usechain Community,

It’s nearly 3 months over in 2019 and as we wrote down on the roadmap, we 0cxare here to announce that Usechain will officially launch the Mainnet at Q1, 2019， and exactly, March 31.

What we have done in 2019?

The Dapp R&D team spent lots of energy on developing the Usechain app in the past 4 months. The app has the functions and products of transferring, lottery, predictions market for various indices, stocks and commodities market, futures trading, wealth management which is in Chinese, an English version will come out in a few months.

The operating team talked with different entity industries to build USE token economy. So far, we are working with diners, hotels, vineyards, tourist resorts, and insurance companies which are mainly in China, to help them issue tokens to do pre-paid card business and fine granular level marketing using tokens.

Now we come to the core of this announcement — the Usechain Mainnet.

On March 31, we will launch the Mainnet (alpha) to show the stage achievement contributed by our blockchain R&D team in the past 15 months.

The Usechain blockchain consists of a committee, miners, real-name users, and anonymous users.

The committee will be selected by the community. Decision making, jurisdiction, and qualified miners verification are the rights entitled to the committee.

How to be a miner on Usechain network?

To become a miner on Usechain network, you need to be a real-name registered user, and to avoid waste on computing power and hard fork, miners will need to pay a certain amount of deposit. According to the RPOW algorithm, miners will be chosen randomly.

More details on the rules of Usechain mainnet will be given out in the next couple of weeks, stay tuned.

We always appreciate your support. Let’s make blockchain different!
