What is blockchain, what is big data

1, blockchain: is a new application model of computer technology such as distributed data storage, peer-to-peer transmission, *** knowledge mechanism, encryption algorithms. The so-called *** knowledge mechanism is a mathematical algorithm in the blockchain system to realize the establishment of trust between different nodes and access to rights and interests .

Blockchain (Blockchain) is an important concept of Bitcoin, the currency joint Tsinghua University Wudaokou Finance School of Internet Finance Laboratory, Sina Science and Technology released the "2014-2016 Global Bitcoin Development Research Report" mentions that blockchain is the underlying technology and infrastructure of Bitcoin[2] ? It is essentially a decentralized database that also serves as the underlying technology for Bitcoin. The blockchain is a string of data blocks generated using cryptographic methods of correlation, each of which contains information about a single Bitcoin network transaction that is used to verify the validity of its information (anti-counterfeiting) and to generate the next block.

2. Big data: refers to a collection of data that cannot be captured, managed, and processed within a certain timeframe using conventional software tools, and is a massive, high-growth, and diversified information asset that requires a new processing model in order to have stronger decision-making, insight discovery, and process optimization capabilities.
