What is a Bitcoin full node? How many Bitcoin full nodes are there? This question is not clear to many friends. Today, we will give you a detailed analysis of nodes, full nodes, and Bitcoin full nodes to help you better and more completely understand Bitcoin full nodes. Before talking about what a Bitcoin full node is, let's talk about what a full node is.

A full node is a node with a complete blockchain ledger. A full node needs to occupy memory to synchronize all blockchain data, and can independently verify all transactions on the blockchain and update data in real time. The main role of a full node in a blockchain distributed ledger is to be responsible for the broadcast and verification of blockchain transactions.

So what is a node?

A node is a network node in a blockchain distributed ledger system. It connects to servers, computers and other devices through the network. Different types of blockchains have different ways of becoming nodes. For example, Bitcoin participates in transactions and mining, and EOS participates in elections to become a node.

The following is what a Bitcoin full node is. 

A Bitcoin full node is a node that downloads and preserves complete blockchain data by loading a Bitcoin client (including BitcoinUnlimited and Bitcoincore).

Before February 2018, the number of global Bitcoin full nodes had been relatively stable at around 10,000 points, responsible for the broadcast and verification of Bitcoin transactions. The number of full nodes in China accounted for about 5% to 8% of the world. However, it suddenly surged since February, and until March, the global market share soared to 17%, and the global ranking also surpassed Germany, which had always been ranked second, and jumped to second place in the world.

Because of the congestion of the blockchain transaction network, the author solved the problem by adjusting the broadcast communication, information encryption and decryption, consensus mechanism, and transaction verification mechanism. In the entire Bitcoin network, from miners to ordinary users can be regarded as a node in the Bitcoin network, but because Bitcoin has the characteristics of multi-centralization, its important role in the entire network is
Bitcoin full nodes.

In the early days when there were very few Bitcoin users, all clients running computers in the Bitcoin network could be regarded as full nodes. These nodes stored the data in the entire Bitcoin blockchain network. Every time a transaction was generated in the network, the node receiving the information would verify the security and compliance of the transaction information, and after the verification, it would be broadcast to other nodes in the entire network. Once the data was generated, it could not be tampered with.

Through the above content, I believe everyone has a comprehensive understanding of what a Bitcoin full node is? It can be seen that the more Bitcoin full nodes there are, the more secure the Bitcoin blockchain network is.
