What is blockchain technology? What it might be used for in the future

Blockchain is a distributed database that consists of a series of blocks of data arranged in chronological order and cryptographically guaranteed to be untamperable and unforgeable. Blockchain technology originally originated as the underlying technology for Bitcoin and is used to decentralize and de-trust the maintenance of a reliable database.

Compared to traditional networks, blockchain has the property that data is difficult to tamper with and forge, making the information recorded on blockchain more authentic and reliable, and enabling it to solve the problem of people distrusting each other.

In addition to the above decentralization and anti-forgery and anti-tampering effects, blockchain technology can also ensure that all data is open and transparent, and can also achieve data traceability; it can also be applied to many other fields, such as digital currency, supply chain management, copyright protection and so on. It can provide more secure, reliable and efficient solutions, while also facilitating the realization of transparency, justice and trust.
