What are the main underlying platforms of blockchain
of course, the most substantial progress has been made by coin Ying China, which has introced blockchain and digital currency into the crowdfunding instry. At present, a crowdfunding project has been successfully completed.
Blockchain platforms include Ethereum, Asch and other underlying application development platforms
Ethereum, an open source public blockchain platform with smart contract function, provides decentralized Ethereum virtual machine to process point-to-point contract through its special cryptocurrency ether (ETH)
arch, a decentralized application platform based on side chain technology. Asch is designed to lower the threshold of developers, such as using JavaScript as the application programming language and supporting relational database to store transaction data, which is believed to be very attractive to developers and small and medium-sized enterprises
extended data
in 2008, Nakamoto first proposed the concept of blockchain. In the following years, blockchain has become the core component of electronic currency bitcoin: public account book for all transactions
by using peer-to-peer network and distributed timestamp server, the blockchain database can be managed independently. The blockchain invented for bitcoin makes it the first digital currency to solve the problem of repeated consumption. Bitcoin's design is a source of inspiration for other applications
bitcoin is the absolute mainstream of digital currency, and digital currency is in full bloom. Bitcoin, litecoin, dogecoin, dashcoin are common. In addition to currency application, there are various derivative applications, such as Ethereum, Asch and other underlying application development platforms, as well as NXT, SIA, bitstocks, maidsafe, ripple and other instrial applications
cross border payment, supply chain finance, insurance, digital bill, asset securitization, bank credit reference and other fields
① cross border payment. Due to the characteristics of disintermediation of blockchain, openness, transparency and non tampering of transactions, no third-party payment institutions join in, which shortens the payment cycle, reces costs and increases the transparency of transactions< (2) digital bill. Blockchain has the characteristics of disintermediation, system stability, consensus mechanism and tamper proof, which can rece the operational risk, market risk and moral risk in the traditional centralized system< (3) credit management. In the field of credit investigation, blockchain has the characteristics of decentralization, distrust, timestamp, asymmetric encryption and smart contract, which ensures that limited and controllable credit data sharing and verification can be realized on the basis of effective protection of data privacy< (4) asset securitization. The characteristics of blockchain disintermediation, consensus mechanism and non tampering can increase the efficiency of data flow, rece costs, monitor the real situation of assets in real time, and ensure the trust of all parties in the transaction chain on the underlying assets< (5) supply chain finance. Due to the characteristics of disintermediation, consensus mechanism and non tampering of blockchain, it does not need a third-party credit enhancement agency to verify the authenticity of various relevant vouchers on the supply chain, so as to rece the financing cost and financing cycle< (6) insurance business. With the development of blockchain technology, personal health status, accident records and other information may be uploaded to the blockchain in the future, so that insurance companies can obtain risk information more timely and accurately when customers take out insurance, so as to rece underwriting costs and improve efficiency. The sharing transparency of blockchain reces the information asymmetry and the risk of adverse selection; The characteristics of its history can be traced, which is concive to recing the moral hazard, thus recing the difficulty and cost of insurance management.
the second category of blockchain projects is platform. The main function of platform projects is to establish a technical platform to meet the technical requirements of various blockchain application development
in short, platform applications allow developers to directly issue digital assets and write smart contracts on the blockchain. Smart contract is a computer program running on the blockchain database, which can be executed by itself under the condition of meeting the source code setting
for example, you develop a smart contract based on the house rent protocol on the blockchain. When the owner receives the rent, it will trigger automatic execution and give the security key of the apartment to the tenant
the main function of platform blockchain projects is to establish the underlying technology platform, so that developers can do application development on the underlying technology platform. A considerable number of platforms are still in the development state. As of January 2018, Ethereum has the largest market value.
