Today we started to get the intensity.
Start trying to learn what a node is in a blockchain?
1. Start with the "traditional database":
Imagine that you go to a bank to deposit money, and the bank's job is to manage the ledger (record your deposits and withdrawals). The bank's database holds all the customer's account information, and only the bank can modify it.
This model is called centralization because all data is managed by a centralized bank, and only the bank has access to modify the data.

2. How blockchain can change this:
In the world of blockchain, there are no banks and no centralized institutions. Data is stored and managed decentralized. That is, everyone can have a copy of the ledger on their own computer.
These computers (devices) are called nodes. Each node keeps a record of all transactions on the blockchain and works together to ensure that each record is correct.
