Speaking of blockchain technology, it has entered the field of vision of more and more people. As a brand-new information transmission technology, many investors will think that blockchain is a very abstract concept and not easy to understand. We can actually understand this technology from the perspective of implementation effects. The effect achieved by blockchain information transmission is similar to that of WeChat group chat. If you send a message in the group chat, everyone in the group can know it. Blockchain is also In this way, although this example is very simple, we should be able to understand that the function of blockchain cannot be underestimated. So what exactly is this blockchain technology? Everyone wants to know, is it computer technology? Let the editor of the currency circle talk about it below.

 What exactly is blockchain technology?

Blockchain is a distributed database system [1] that is participated by nodes. Its characteristics are that it cannot be changed or forged. It can also be understood as an account book system (ledger). It is an important concept of Bitcoin, a copy of the complete Bitcoin blockchain, recording every transaction of its token. Through this information, we can find the value of each address at any point in history.

The blockchain is composed of a series of data blocks generated using cryptographic methods. Each block contains the hash value of the previous block, starting from the genesis block.
block) begins to connect to the current block to form a block chain. Each block is guaranteed to be generated after the previous block in chronological order, otherwise the hash value of the previous block is unknown. These characteristics make Bitcoin’s double-spend
spending) is very difficult. Blockchain is the core innovation of Bitcoin.

The emergence of the concept of blockchain was first mentioned in Satoshi Nakamoto's Bitcoin white paper [2], but it is based on the proof-of-work chain.
chain), the following is Satoshi Nakamoto’s description of the concept of blockchain:

A timestamp server timestamps a set of data in the form of a block by randomly hashing it and broadcasting the random hash, just like in a news or world newsgroup network (Usenet). Same as the post. Obviously, this timestamp can prove that specific data must indeed exist at a specific time, because only if it exists at that time can the corresponding random hash value be obtained. Each timestamp should incorporate the previous timestamp into its random hash value, and each subsequent timestamp should reinforcing the previous timestamp, thus forming a chain.

 Is blockchain technology a computer technology?

Blockchain technology is a brand-new information transmission technology and belongs to computer technology. Blockchain technology is the core of many encrypted digital currencies, including Bitcoin, Ethereum, Litecoin, Dogecoin, etc. The way to maintain the blockchain is proof-of-work
of-work), proof-of-stake, etc.

The core advantages of blockchain architecture include:

1. Any node can create a transaction. After a period of confirmation, it can be reasonably confirmed whether the transaction is valid. The blockchain can effectively prevent the occurrence of double-spending problems.

2. The cost of trying to rewrite or modify transaction records is very high.

3. Blockchain implements two types of records: transactions and blocks. Transactions are the actual data stored on the blockchain, while blocks are records confirming when and in what order certain transactions became part of the blockchain database. Transactions are created by participants using the system in the normal course (in the case of cryptocurrencies, a transaction is created by Bob sending tokens to Alice), while blocks are created by what we call Units of miners are responsible for creation.

The above is the specific elaboration of the editor of the currency circle on the two questions of what exactly is blockchain technology and is blockchain technology a computer technology. As the underlying technology of digital currency, blockchain has now attracted great attention in the financial field. Some well-known financial institutions such as Goldman Sachs, JPMorgan Chase, and HSBC have cooperated with various blockchain companies. , they are all studying the application of blockchain technology in financial markets. The global World Economic Forum boldly predicts that 10% of the world's GDP will be stored on the blockchain network by 2027. This makes many investors full of wonderful imaginations about the future blockchain network.
