What are the underlying platforms of blockchain

        The earliest blockchain development was based on the blockchain network of bitcoin. Because bitcoin is the most widely used and truly decentralized in the world, as far as blockchain applications are concerned, bitcoin is the most powerful anchor in the world and has the greatest authority. Therefore, there are many blockchain technologies around bitcoin, which are not described here one by one, but only for the introduction of entry-level development. There are two ways to develop blockchain network based on bitcoin. One is relatively simple and is developed based on API. O is the most popular bitcoin wallet and block query website of bitcoin, and also provides bitcoin and its block related APIs.
        Blockchain. Info provides API libraries in many mainstream languages, including bitcoin wallets, payments, blocks, transaction data, market data and other APIs. It can be said that besides bitcoin, Ethereum is currently the most eye-catching blockchain platform. Ethereum is a Turing complete blockchain one-stop development platform, which uses multiple programming languages to implement the protocol, and uses the client written in go language as the default client (that is, the method of interacting with Ethereum network, which supports clients in other languages). The application based on Ethereum platform is smart contract, which is the core of Ethereum.
        Each smart contract has a unique Ethernet address. When the user sends a transaction to the address of the contract (at this time, it will consume fuel costs, that is, handling costs), the contract will be activated. Then, according to the additional information in the transaction, the contract will run its own code and finally return a result. There are several languages to write Ethereum smart contracts, including JavaScript like solidity, serpent close to python, and LISP like lll. At present, the mainstream is solidity, which is recommended for everyone. After the solid contract is compiled and sent to the network, you can test and use the smart contract through Ethereum's mist client, or you can call it using Ethereum's web3.jsjavascriptapi to build web applications that can interact with it.
        Ibmhyperledger is also called fabric. Its goal is to build a super ledger jointly maintained by the whole society. Fabric originated from IBM. Its original intention is to serve industrial production. IBM will open source 44000 lines of code, which is a great contribution. It gives us the opportunity to explore the principle of blockchain different from bitcoin so closely. As far as Elwin knows, fabric has not yet entered the real commercial stage, and it is more about experimentation and exploration. However, compared with many other blockchains, it is more reliable and reliable from the technical background. There are two ways to develop blockchain based on hyperledger. One is based on super cloud (the super cloud platform developed by IBM China Research Institute provides various cloud services). It provides blockchain development and testing environment for blockchain enthusiasts and developers. Through the super cloud platform, users can create a multi node blockchain based on hyperledgerfabric for free and super fast, and debug smart contracts on their own chain.
        Hyperledgerfabric's contract is based on the go language, which is relatively simple to use. Lisk is a new generation blockchain platform, which allows the development of JavaScript (javascript technology again, which engineers have noticed) and distributed applications to use an easy-to-use, fully functional ecological blockchain system. Compared with the blockchain bottom layers mentioned above, lisk's application advantage lies not only in that it is the first decentralized application solution completely written in JavaScript, but also in that it adds each application to the separate side chain of lisk.
        Friends who have used bitcoin and Ethereum know that because bitcoin and Ethereum have only one main chain, all functions and data are added to this main chain, resulting in rapid expansion of blocks, huge block size, and ultra long synchronization time, which is a very painful experience. Lisk's side chain mode provides a way to solve the problem of network congestion when dealing with high transaction volume. Users need to download the corresponding side chain only when using relevant applications, which greatly reduces invalid synchronization data and maintains the efficient operation of the whole lisk network. Moreover, the speed of lisk network will continue to accelerate with the passage of time, showing its special advantages.
        Secondly, compared with Ethereum and hyperledgefabric blockchains with smart contracts as the core, the purpose of lisk blockchain is not to create smart contracts, but to use liskapsdk framework to develop different applications and functions. The weblog blockchain platform is the research and development achievements of the underlying technology of the weblog blockchain and the basic platform for commercial delivery. In addition to serving the public weblog chain, the weblog blockchain platform is also the basic platform for weblog to build private chains and alliance chains for customers. In the process of continuous improvement, the platform will provide powerful basic services that can meet complex application scenarios, such as distributed ledgers, P2P, smart contracts, user systems and permissions, privacy and security, as well as management functions and standard interfaces for these services.
        At the same time, the throughput and stability of standard services are also the focus of Weblog research and development. On this basis, customers and weblog technology jointly build innovative blockchain applications.
