What is a blockchain and what can it do? Let's put it in common words ~ thank you.

1. Blockchain is a new application mode of distributed data storage, point-to-point transmission, * * identification mechanism, encryption algorithm and other computer technologies.

Blockchain is an important concept of Bitcoin. It is essentially a database without intermediary. At the same time, as the underlying technology of Bitcoin, it is a series of data blocks related by cryptography. Each data block contains the information of online transaction of Bitcoin, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block.

Second, the application

1, art industry

Ascribe allows artists to declare their ownership by using blockchain technology and publish numbered and limited-edition works, which can be aimed at the digital form of any type of artistic works. It even includes a trading market where artists can buy and sell through their websites without any intermediary services.

2. Legal profession

BitProof is the most advanced among many document timestamp applications that have appeared in recent years, and it will make the traditional notarization method a thing of the past. Compared with the free versions including Blocksgin and OriginStaemp, BitProof provides more services, including an intellectual property service. Interestingly, BitProof recently cooperated with an IT school in San Francisco to put students' academic credentials on the blockchain, completely redefining how to handle and use diplomas and student ID cards.

3. Develop industry

Colu is the first company to allow other companies to issue digital assets, and they can "token" various assets, which impressed many people. Although the free bitcoin wallet Counerparty also allows simple tokens to be issued and traded among other wallet holders, Colu tokens can be set to various states and types, and can leave or return to the system. When the data stored in the blockchain is too large, it can be stored on BitTorrent's network.

4. Real estate industry

They plan to make the whole industrial chain process more modern and solve all kinds of problems that people face when they participate in real estate, including naming process, land registration, agency and so on.

5. Internet of Things

A possible application scenario is to generate corresponding behaviors through transactions, assign an address to each device, and inject a certain fee into the address to carry out related actions, thus realizing the application of the Internet of Things. Similar to: PM2.5 monitoring point data collection, server leasing, webcam data call, DNS server, etc.

6. Insurance industry

In the past two years, the hottest topic in the field of science and technology is inseparable from blockchain technology. This underlying technology, which was born out of Bitcoin, has proved its highly safe and reliable architecture and algorithm design with more than seven years of stable operation. At the same time, with the help of innovative technologies such as distributed account books and smart contracts, it has opened up a huge imagination space for industrial upgrading in many industries. Even industry experts predict that blockchain technology will set off the second Internet revolution.

Extended data:

In 2008, Satoshi Nakamoto put forward the concept of "blockchain" in the White Paper on Bitcoin, and established the Bitcoin network in 2009, and developed the first block, namely "Create Block".

The blockchain * * * enjoyment value system was first imitated by many cryptocurrencies, and the workload proof and algorithm were improved, such as the adoption of equity proof and SCrypt algorithm. Subsequently, the blockchain ecosystem continued to evolve on a global scale, and the first token trading ICO, smart contract blockchain Ethereum, asset tokenization with "light ownership and heavy use rights" and blockchain countries appeared.

At present, people are using this * * * enjoyment value system to develop decentralized computer programs (DAPP) in all walks of life, and to establish decentralized autonomous organizations and decentralized autonomous associations (DAS) all over the world.
