HTTP protocol into interstellar search
the distributed storage of blockchain is also just needed
the arrival of 5g increases the demand for storage
the decentralized storage of blockchain will be applied quickly
the definition of blockchain
in a narrow sense, blockchain is a kind of chained data structure that combines data blocks in a sequential way according to the time sequence, and it is a distributed account book that can not be tampered with and forged by means of cryptography
broadly speaking, blockchain technology uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, and uses cryptography to ensure the security of data transmission and access It is a new distributed infrastructure and computing method to program and operate data by using intelligent contract composed of automated script code
there are many channels to learn blockchain
① you can buy some books related to blockchain, learn some knowledge related to blockchain, take notes in your spare time, and consult relevant information
② watch some videos of blockchain on the Internet, the contents of which are easy to understand, with relevant examples, It's also a very good way to learn
③ you can take part in some offline blockchain learning exchange meetings, or take part in some training courses, and some teachers will answer questions for you
to sum up,
all roads lead to Rome. There are many channels to learn blockchain, and the best one is suitable for you
In popular language, blockchain is an Internet form of information flow and use, which makes information interaction anonymous, unchangeable, decentralized, traceable, and easy to transfer. At present, the most mature proct using this technology is bitcoin. Therefore, bitcoin, which uses blockchain technology, has the characteristics of anonymity, immutability and decentralization
using blockchain technology can reflect (or realize) the value of various kinds of data, and facilitate the transaction of useful data. For example, the big data of each big bank, Alibaba, Tencent, Jingdong and the network will not be shared, but if blockchain technology is used, it may be shared, Because of the anonymity of blockchain, it can only obtain relevant data and avoid the disclosure of private data.
