World Wide Web Testnet Beta version of the award-winning global public beta

Reporter: pencil boxn

Following the release of the Testnet Alpha version in early November, the team of Wanwei Chain has been repaired and perfected. Beta Testnet version was officially released on December 19 and publicly tested for the global community. The beta version of Testnet includes:n
n1. Improved testing of Alpha Testnet version of the problem.n
nn2. Added Wanchain GUI wallet for Mac, Windows and Ubuntu platforms.n
nnCompleted the large-scale multi-regional nodes of the bottom of the test.n
nn4. Completed the normal transaction and privacy transactions test two trading modes.n
nn5. Support the deployment of smart contracts (currently not supported from the GUI wallet for deployment).n
nParticipating in tests and submitting valuable test feedback and reports based on the project rewards program will receive WAN rewards from the Incentive Committee; by convention, officials will be rewarded for submitting request pull requests either on GitHub or on the World Wide Web platform Deploy smart contracts to enrich the participants in the ecology of the M u0026 E chain. Officials will also provide specialized technical support.n
What is the chain?n
Wanwick is a public chain project based on Ethereum technology. The most important function of this chain is to be a connector for different blockchains. Wanxiang Chain proposed to create a digital economy, financial infrastructure, from a technical point of view to solve the cross-chain issues, and privacy issues. What does this have to do with finance? The problem of cross-link is essentially to solve the problem of accounting when the same asset on two ledgers occurs. From ancient banks to modern banks, each has its own separate account. When their clients transfer assets between different banks, different banks need to solve the problem of accurately accounting for both books. In essence, the central bank’s liquidation system, third-party payment, CUP and other institutions are all from different dimensions to solve the above problems (centralized way), the existence of R3 is also to establish a blockchain mechanism to solve the above problems . Therefore, the transfer of assets under different scenarios of accounting is the most basic financial issues, all the financial services to carry out the premise.n
With the rapid development of blockchain and digital assets, there are more and more blockchain networks and more and more assets. It is more important to solve the problem of cross-book transfer of assets in the blockchain world. At present, the centralized institutions or individuals such as exchanges are the main ways to solve the above problems, and these methods have greatly promoted the application and development of digital assets in a certain period of time. However, the centralized mechanism inevitably brings about security issues, trust issues and oligopolies in traditional finance. This is contrary to the notion of a decentralized, open and fair management of the blockchain. From a technical point of view, it is the nature of cross-link to connect different blockchain ledgers and blockchain to solve the blockchain problem. From an application point of view, only by solving the problem of value transfer, the financial innovation value and network effect of blockchain can be more significant.n
What is the technical characteristics of the chain? What are the innovations?n
In cross-chain issues, the chain of innovation is mainly reflected in the lock account management and consensus model design. Locking account mechanism is the key to cross-link technology. When assets cross-chain transfer, the assets in the original chain must be securely locked. When the assets are returned to the original chain, the assets can be unlocked. The current mainstream approach is the same as that proposed by Blockstream in the side-chain solution, which is to lock the account with multiple signatures. Multi-signature protocols are fixed, such as Bitcoin, which has the risk of stolen private keys or the loss of private keys for a limited number of multiple signatures.n

Innovation one: based on the elliptic curve of the threshold key schemen
Wanhuan chain based on the elliptic curve of the threshold key scheme. At present, the mainstream blockchain adopts the elliptic curve, that is, a set of keys that can manage the locking accounts of different blockchain. The advantage of the threshold-key scheme is that the signature corresponding to the private key can be divided into “fragments” of n in number, and only x (x
