TPCourses19 — What Are Blockchain Nodes?

Definition of blockchain nodes
The blockchain node is a server for acting as a communication point that may perform different functions in a region. In the Internet, if all the data being run in a server, then this server is a node. So, the nodes in the blockchain network are equivalent to computers or server terminals tostore block data.

Classification of blockchain nodes
According to the degree of decentralization of the wallet, wallets can be divided into full-node wallets, light-node wallets, and centralized wallets.

A full-node wallet is to synchronize all data on the blockchain to the wallet, which will take up huge storage. It is the full-node wallet to sync all data on the blockchain that can be completely decentralized.

TokenPocket is a light-node wallet and has a full-node server that can synchronize all data on the chain to achieve complete decentralization. The data is divided and distributed according to different wallet addresses and demands, so that users can use the wallet quickly and conveniently.

What should I do if the node is unstable?
If you fail to transfer tokens, or the current custom network cannot get the balance, or an incomprehensible notice such as “unknown” appears, it may be because the connected node is unstable currently. In this case, you can change a node with fast speed and large block height through [Me]-[Settings]-[Nodes Setting].
