About the currency
8 years, the currency to create a myth - nearly 3 million times in the price of the domestic price once reached 20000 yuan, in the mythology, different people see a different story, speculators saw the chance to make money, technology geek saw the change of future technology, the traditional financial institutions may see a growing ghost,

The currency was born, the beginning of the revolution?
Electronic payment industry mentioned, we first think of are either pay treasure or WeChat, in fact, behind the two giants, and two researchers had problems, is also a real display electronic payment industry (ambition) problem:
How a not by a third party of authority, can be in between the two sides in the demand for online transfer;
The second is how can record at the same time in the electronic transfer of payment information, avoid repetition to pay and ensure the security of funds,
Two problems to solve, would mean a set of independent electronic currency system, the basic with the relationship between the banking system, there is no any money now,
About the etheric fang
In 2013, the 19-year-old Vitalik Buterin in a theme of "white paper on the etheric fang: the next generation of intelligent connection and decentralized application platform" in the book of the first mentioned the idea of the etheric fang, then in 2014, the algorithm of the etheric fang and formal agreement be born, and raised $150 million, while the system itself on July 30, 2015, finally completed,

There is a very need us to understand the problem, is also the competition of the platform's biggest potential and debate focus: namely the etheric lane is more than just an electronic currency, is also a platform based on block chain and intelligent contract system, it can be used to build the application, and electronic money is one of the forms of the technology,
Similar financial instruments, property, domain names, and more complex financial products trading, derivatives, bet against, as well as the identity and personal credit registry system involves information and wealth distribution and records of link, the etheric fang in theory, have very big development space,
Intelligent contract, for example:
Smart contracts are etheric lane to the rapid expansion of electronic currency and block chain important contribution in the field of technology, it can be seen as a way to use digital means to ensure the safety value exchange links, able to form a transparent, means of disintermediation, save out such as lawyers, notaries and other professionals to provide expensive service, turning to perform intelligent digital terms of contract itself to ensure the validity of the contract,
About Rayleigh wave c
Rayleigh wave currency is the basis of the Ripple network currency, it can be in the Ripple network flow, total number of 100 billion, and gradually reduce along with the increase in trade, operating company for Rayleigh wave currency Ripple Labs (its predecessor is OpenCoin),

Rayleigh wave of money is the only currency in ripple system, its different from other currencies in the ripple system, other currencies such as the CNY and USD cannot cross gateway withdrawal, in other words, A gateway of CNY only in A gateway withdrawal, if in the gateway B withdrawal, must through the ripple system function into the deity gateway CNY can B to B gateway withdrawal, and have no this aspect of the Rayleigh wave currency restrictions, it is general in the ripple system,
On January 1, 2018, Rayleigh wave currency (ripple) transaction prices jumped nearly 56% last Friday, a record high, market capitalisation overtook the etheric COINS, currency became the second big encryption,
Thousands of melting (VAC) chain
VAC financial chain, the Value added chain, it is in the development of the currency and etheric lane outside the third block chain ecosystem, and is committed to expanding block chain technology and technical application of boundary, make ordinary Internet users can feel the Value of the block chain technology,

在VAC 系统中,可以通过价值传输协议(Value Transfer Protocol)来实现点对点的价值转移,并根据此协议,构建一个支持不同行业的增值积分业务体系(银行积分,移动通信积分,航空及各大积分平台等)去中心化的应用开发平台(DAPP Platform),VAC 系统通过良好的设计原则和设计策略来实现,例如兼容性原则,模块化设计策略,安全性策略和易用性策略, 从技术角度分析,VAC 致力于实现 首个兼容 BIP (基于 UTXO 模型)的 POS智能合约平台,并通过 Identity ,Oracle和 Data feeds的引入,在合理合规性方面,符合不同行业的监管需求,在 VAC 的公链(Public Blockchain)系统中,在共识机制上,从去中心化程度,实用性,技术可靠性考虑,将以 Proof of Stake为基础,加入节点在线激励因素(Incentive Factor),形成 IPOS(Incentive POS)的共识协议,在 VAC 的联盟链中(Permissioned Blockchain),将采用 VAC 开发者提出的与 Raft 融合的 Proof of Time 共识协议,使得在联盟链或私链中,达成共识的时间大大缩短(BlockTime:250ms,Confirmation Time:750ms--1s),
VAC system will be based on UTXO model to implement the contract based on the block chain, mainly consider the following factors: (1) and the currency ecological compatibility; (2) the BJP long-term evolution protocol compatibility; (3) the trading ability of parallel processing/privacy/traceability,
In the VAC system, the block chain contracts (Blockchain Contract) into intelligent (Smart Contract) and the Simple agreement (Simple Contract), in addition to support intelligent Contract, through the introduction of factors under the chain, formed in line with the real world business logic block chain Simple Contract, the other in a virtual machine, in VAC test network, will be compatible with EVM entry, late by mark different kinds of virtual machine, can support more virtual machine, including LLVM and Lua and EVM2.0. As well as the development of more stringent VM programming language,
In the VAC system, through the design of the Oracle and Data feeds, can let the block chain intelligent contract more ground and operator business rules, set up the real world to block chain Bridges in the world, and VAC system, the intelligent contract to manage the participants' identity information, will be based on VAC system of financial services to provide better support,
Final strategy for Mobile end (Go Mobile) is also a strategy of VAC pay special attention to, in the ecological system of VAC, will with the third party developers, together from a technical architecture for providing Mobile services, including: Mobile wallet, Mobile terminal DAPP applications, intelligent Mobile client service contract, also encourages third-party developers, chain development blocks Mobile client service, together to promote floor of block chain technology,
VAC system of public key cryptography scheme
Public key in the etheric lane is now done by precompiled contracts, in the VAC system, will be done by the opcode of VM, in the league chain of VAC (Permissioned Blockchain), fused with the Raft with VAC developers put forward the Proof of Time consensus agreement, in union in the chain chain or private, greatly reduces the Time of the consensus (BlockTime: 250 ms, Confirmation Time: 750 ms - 1 s),
Melt chain (VAC) is a public chain, he is block chain technology has a new breakthrough, on the application of the block chain technology is a major step forward, the value-added chain of integral system decentralized applications, through the integration of the value-added business systems and decentralized applications will all walks of life, to varying degrees of integral solving different platforms,
1, scattered, not general, different industry, different enterprise to issue different points, the integral of the query and use convenient, cause the integral can be chicken ribs, did not have the effect of the user guide,
2, the integral can't transfer, according to statistics, the user is not correctly guide consumption, etc.,
3, integral issue opaque, the traditional integral distribution based on the database, the data of the high cost of maintenance and small points of the risk of tampering with fake makes the lack of credibility and achieve mutual combination, make integral value in circulation, through the integration of the technology to create a block chain chain, similar to electric business platform, to achieve the common points, through the common points, do the members of the joint between different platforms, further relates to a different platform, can make various private platform in idle integral value, at the same time support public chain, chain, the chain of private different applications, such as the type of scenario, fast and business systems integration, all melt chain vac framework supports interoperability across between different block chain chain, support chain blocks and the interaction between the traditional network,

Learning how to learn ah, thank you.

CodePudding user response:

Thanks for, study hard to learn,

CodePudding user response:

Don't know the new digital currency and yao never abroad
