Ethereum universal

1. If a few years ago, maybe I would not hesitate to say bitcoin, but in recent years, the development of bitcoin is a bit unsatisfactory. Today's latest information report also shows that the price of bitcoin has fallen below $10000. If you only hold bitcoin, it may not be good news, but it has no effect on the virtual currency contract transaction, which can be traded in both directions

if you don't have a lot of spare money on hand, it's a good choice to invest in virtual currency at this time. With a threshold of several hundred yuan, new users of the realm can also get a $50 coupon, which will not affect our lives, but also bring considerable benefits<

the investment mode that can also trade is not only suitable for young people, but also for the elderly, because it does not require you to have much deep investment experience, as long as you know how to judge the direction of price rise and fall, and the trading time is relatively free, 24 hours a day can be operated at any time.

2. blockchain is a technology, but it is not a single technology, but the result of the integration of a variety of technologies, including cryptography, mathematics, economics, network science and so on. You can think of it as a distributed shared accounting technology, or as a database, but the database is jointly maintained by all nodes in the chain, and each node has an account book. Because the account books of all nodes are consistent, different nodes can trust each other, and there is no doubt about the data, so we all say that the blockchain has realized trust technically. For detailed professional technology, you can consult some professional technology companies, such as Jinbo technology, which focuses on the development of blockchain related procts, professional R & D team and perfect after-sales service, and you can consult by telephone.

(1) The underlying platform of the blockchain is a domestic independent and controllable blockchain platform developed by the science and technology of the blockchain. With the characteristics of high performance, high availability, scalability, easy operation and maintenance, strong privacy protection, and hybrid storage, the platform cooperates with the data sharing and security computing platform bitxmesh, the blockchain open service platform filoop, the supply chain finance platform filolink, and other platforms The deposit service platform filoink and the smart contract security R & D platform meshsec can better support the applications of enterprises, governments, instry alliances and other instries, and promote the efficient circulation of value among multiple institutions

(2) JD chain is the underlying framework of enterprise level blockchain independently developed by JD, and its birth marks that JD has started the construction of "Zhizhen ecology" based on the baas platform of blockchain and the underlying chain of "jdchain". Relying on the "one key deployment" capability of multiple optimization implementation, JD Zhizhen chain service platform has achieved the leading second level blockchain node deployment. In addition, it also has the core advantages of open compatibility with a variety of underlying, enterprise level dynamic networking and other mature applications. The timely launch of JD Zhizhen chain will effectively promote the large-scale implementation of enterprise level blockchain applications in various instries, and promote the construction of China's and global trust economy

(3) thunderchain is a blockchain application project independently researched and developed by netxin technology under thunderchain, which has high concurrency and second level confirmation capability of millions of TPS. Based on the research and development of high-performance blockchain procts, Xunlei has built an open platform of Xunlei chain, which helps enterprises or indivial developers to deploy smart contracts, easily realize the proct and service on the chain, and make the application development of blockchain more convenient

(4) Jingtong blockchain

Jingtong blockchain is the core underlying technology of Jingtong technology's blockchain with independent intellectual property rights. It is an effective decentralized Internet trading network based on blockchain technology, which adopts layered design (5 layers) underlying platform and multi language intelligent contract system, and has realized cross chain function. It has multi-level, all-round and one-stop service capabilities such as private chain, cloud chain and alliance chain. The layout of instry and regional ecology has taken shape

in addition to the above blockchain procts, there are community led LTC, cosmos, iota, Neuros, nuls, MOAC, etc., and enterprise led ripple, stellar, Weizhong bcos, network xuperchain, Huawei, Ping'an, Wanxiang, ant financial services, Zhongan, Bubi, matrix element, secret ape, zhongxiangbit, complex beauty, Shanghai Lianjing, etc

extended data:

blockchain is far more than a technology, which involves the spirit of "multi-party cooperation". In modern society, a lot of things must rely on everyone's cooperation to achieve 1 + 1 & gt; But we should try our best to avoid the problem of "information asymmetry" in cooperation

therefore, members of the alliance should keep accounts and share data together, and make everything public to eliminate "information asymmetry", so as to protect everyone's interests and make the business environment develop healthily. Honest work will get e benefits, if cheating will naturally be known to all. Technology is the foundation to help achieve this pattern. This is the more important "blockchain thinking"

4. Blockchain (English: blockchain or blockchain) is a kind of distributed database, originated from bitcoin. The concept was put forward in the white paper of Nakamoto Tsung. Blockchain is an underlying technology of bitcoin, and bitcoin is only an application of blockchain
as we all know, bitcoin can realize point-to-point value transmission. In addition to bitcoin blockchain, there are many other blockchains, such as Ethereum blockchain. Therefore, we should distinguish the concepts of bitcoin, bitcoin blockchain, blockchain and blockchain technology
blockchain, which is first accompanied by the emergence of digital currency, has recently been widely discussed in the instry for its subversive impact on the existing financial field, and is known as a new round of change after the Internet technology revolution. As a distributed general ledger, this technology will first break out a huge force of change in the financial field: clearing, settlement, remittance, payment, value transmission, innovation and inclusive of the whole financial network, including all income groups, connecting regions and people separated by physical borders, and reshaping the whole economy and society
because blockchain is an open, transparent, traceable and tamper proof distributed general ledger system, blockchain technology can effectively rece the error rate of payment, clearing and settlement steps, and monitor the inflow and outflow of funds in each step, which is an effective means to promote the establishment of an honest society. Therefore, if the regulatory authorities can effectively use this technology, it will help to control the asset status and possible risks of the financial instry
China's blockchain enterprises continue to emerge
since 2015, China's attention and Research on blockchain technology has graally expanded
from the perspective of government departments, Zhou Xiaochuan, governor of the central bank, pointed out in February 2016 that digital currency must be issued by the central bank, and blockchain is an optional technology. Prior to that, the people's Bank of China also held a seminar on digital currency. In addition to the central bank, Zhejiang Province, Beijing and other relevant government departments also expressed their support for blockchain application research last year
from the perspective of enterprises, Wanxiang Group has established a blockchain laboratory, and many blockchain innovation and entrepreneurship enterprises continue to emerge< In addition, a number of instry alliances are being established. In December 2015, blockchain research alliance and blockchain Application Research Center were established; In February 2016, Zhongguancun blockchain instry alliance was established; In April, China ledger officially announced its establishment in Beijing<
blockchain concept stocks become the wind outlet
blockchain is like a database ledger, recording all transaction records. Because of its safety and convenience, this technology has graally attracted the attention of the banking and financial instry. According to the survey report of the world economic forum, it is predicted that by 2025, 10% of the relevant information in the global GDP will be preserved by blockchain technology. Blockchain technology is facing a blue ocean, and related concept stocks are becoming the wind. In A-share listed companies, it is suggested to focus on the concept leading stocks: Feitian integrity, Yuyin shares. In the future, with the fermentation of speculation, other concept stocks are expected to follow suit
