Any computer connected to the Internet can be connected to the blockchain, so there are countless nodes on the blockchain; but the difference is that the blocks on the blockchain are limited, that is, one block is generated every 10 minutes, reaching a certain No more blocks will be added after the quantity.
2. "Chain" refers to connecting blocks together. A simple metaphor: We can think of the blockchain as a big ledger. Every transaction in this ledger can be checked by everyone and is difficult to tamper with.
3. After the node receives it, it broadcasts it to surrounding nodes and spreads the node to the entire network. Each Bitcoin wallet is a node, and a node with a complete blockchain ledger is called a full node.
4. Bitcoin and blockchain are not the same thing. Blockchain is a distributed accounting technology, while Bitcoin is a peer-to-peer digital currency, but Bitcoin uses blockchain as its underlying technology.

The private key can be regarded as a bank password, which is a long string of random numbers generated by the wallet, such as 2W.
