I have introduced to you what blockchain nodes are. I don't know if you have any impression. Blockchain nodes are computers that have installed software related to digital currencies (BTC, Ethereum, Monero, etc.) to participate in peer-to-peer networks. So, what is the basic principle of blockchain nodes? What's the use of blockchain nodes? Next, follow Xiao Bian to have a look.

Basic principles of blockchain nodes

Let's take Bitcoin's blockchain system as an example. The birth time of a new BTC block is set as 10 minutes.

After a transaction is generated, in order to make the whole network recognized and effective, it must first be broadcast to other participating nodes (linked computers) in the blockchain network;

Each node should correctly stamp the ten minute transactions and put them into this block;

If a node solves the mathematical problem of random number and has the legal block accounting right, it will release its transaction with all time stamps tightened for 10 minutes to the whole network, which will be checked by other participating nodes in the whole network;

The BTC system will reward the node that has won the legal block accounting right. After broadcasting, other nodes will check the accuracy of the block accounting. Other nodes are actually solving the math problem at the same time, and they are also timestamping, but they are not faster on that math problem. In other words, they can't win the reward in this block, and they can only find ways in the next block.

Generally speaking, every transaction must be confirmed 6 times, that is, it must be accounted for 6 times in 10 minutes before it can be recognized as a legal transaction in the system. One time accounting is not recognized.

What are the functions of blockchain nodes?

In all kinds of virtual currency networks, customers can start from the role of blockchain nodes if they want to know what blockchain nodes mean. Blockchain nodes have the right to do accounting, and miners at each node can compete fairly for the right to do accounting. The miners on which node first solved the mathematical problem will naturally get the virtual currency of the block award. The virtual currency awarded is the virtual currency dug up by the miners, and this node has also obtained the right to make accounts. In this way, the appearance of blockchain nodes can not only make accounts, but also ensure the normal operation of the virtual currency network. After all, most of the virtual currencies are operated normally by such a mining system, and the emergence of nodes can ensure the security of the network.

The more nodes of virtual currency, the more secure the network will be. For novices, what do you mean by blockchain nodes? Naturally, we know that these nodes are powerful. In addition, according to blockchain technology, customers can also browse what is recorded on the node? For example, the advanced OKLink browser launched in China can directly access and view the transaction details on the node, and directly see whether the transaction status on the node is successful. Naturally, it can also search the balance of digital currency in the wallet and the real-time price of various virtual currencies. Therefore, although the nodes of the blockchain are mysterious, with the OKLink browser, ordinary people can also understand the efficacy of the nodes and the data on the nodes.

Speaking of this, I believe you have a certain understanding of the basic principles of blockchain nodes and the role of blockchain nodes. In general, blockchain nodes have the advantage of promoting economic export, which can accelerate blockchain science popularization and promote the blockchain to return to essence. Blockchain nodes can be online or offline, so blockchain nodes are relatively safe.
