Jingtong and Ethereum

1.

blockchain includes public blockchain, joint (instry) blockchain and private blockchain. Public chain point-to-point e-cash system: bitcoin, smart contract and decentralized application platform: Ethereum

blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies

blockchain is an important concept of bitcoin. In essence, it is a decentralized database. At the same time, as the underlying technology of bitcoin, it is a series of data blocks generated by using cryptographic methods. Each data block contains a batch of bitcoin network transaction information, Used to verify the validity of its information (anti-counterfeiting) and generate the next block

extended data

according to the different degree of blockchain network centralization, three kinds of blockchains under different application scenarios are differentiated:

1. The blockchain with the whole network open and without user authorization mechanism is called public chain

2. The authorized nodes are allowed to join the network, and the information can be viewed according to the authority. It is often used in the inter agency blockchain, which is called alliance chain or instry chain

3. All the nodes in the network are in the hands of one organization, which is called private chain

alliance chain and private chain are also called licensing chain, and public chain is called non licensing chain

blockchain features

1, decentralization. Blockchain technology does not rely on additional third-party management institutions or hardware facilities, and there is no central control. In addition to the self-contained blockchain itself, each node realizes information self verification, transmission and management through distributed accounting and storage. Decentralization is the most prominent and essential feature of blockchain

2. Openness. Blockchain technology is based on open source. In addition to the private information of all parties involved in the transaction is encrypted, the data of blockchain is open to everyone. Anyone can query blockchain data and develop related applications through the open interface, so the information of the whole system is highly transparent

3. Independence. Based on consensus specifications and Protocols (similar to various mathematical algorithms such as hash algorithm used by bitcoin), the whole blockchain system does not rely on other third parties, and all nodes can automatically and safely verify and exchange data in the system without any human intervention

4. Safety. As long as 51% of all data nodes cannot be controlled, the network data cannot be arbitrarily manipulated and modified, which makes the blockchain itself relatively safe and avoids subjective and artificial data changes

5. Anonymity. Unless there are legal requirements, technically speaking, the identity information of each block node does not need to be disclosed or verified, and the information can be transferred anonymously

(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. It depends on the type. It's the cheapest on campus trusteeship, about 350-400 yuan, about 500-600 yuan for ordinary small tables, and about 600-700 yuan for regular Bell's parents. What you get for what you pay for is mainly about your own affordability
please adopt

5. I use token pocket wallet
blockchain wallet is a container containing public key (address) and private key, which is used to keep our digital assets safely. The public key (address) is the authority to view the wallet, which is equivalent to the address of the bank card, while the private key is the authority to operate the wallet, which is equivalent to the password of the bank card. Similar to the private key, there are mnemonic words and wallet file + password. As long as you master one of the three, you will have the ownership of the wallet
the most important feature of blockchain wallet is that it can't be tampered with and anonymous, so we must keep the private key well, otherwise the security of assets can't be guaranteed I the private key in several small paper books and store them separately to prevent loss.)
public key is used to receive or transfer out digital currency, which can tell others. It is equivalent to email address
tokenpocket wallets have various wallets based on ten bottom layers, including EOS, Iost, Ethereum, Tron, binance, BOS, cosmos, Moke, Jingtong, and en. Next, bitcoin wallets will be opened
haha, Xiao has a look at so many unfamiliar words - the ability to support so many people at the bottom is e to the powerful technology.

6. Who can use it on a large scale can become the leader of 3.0 first
