Sure, here's a simplified summary of how blockchain works:

A blockchain is a secure digital ledger that records transactions.
Transactions are verified and added to a "block" of transactions.
Each block is cryptographically secured and linked to the previous block, forming a chain of blocks.
The blocks are stored on multiple computers or nodes in a decentralized network.
In order to add a new block to the chain, it must be validated by the network of nodes using complex mathematical algorithms, a process called "mining".
Miners are incentivized to participate in the network with rewards in the form of cryptocurrency.
Once a block is added to the chain, it becomes part of a permanent and transparent record of all transactions on the blockchain.
