Data in a blockchain is stored in blocks that are linked together in a chronological and cryptographic chain. Here's a breakdown of how this works

1. Block Structure: Each block typically contains:

i ). Data: Depends on the blockchain type. For example, in Bitcoin, it stores transaction details.

ii). Timestamp: When the block was created.

iii). Hash: A cryptographic fingerprint of the block.

iv). Previous Block Hash: Links the block to the one before it, forming a chain.

2. Chaining Blocks:

i). Each new block includes the hash of the previous block.

ii). This makes the blockchain tamper-resistant changing one block would require changing every subsequent block.

3. Distributed Storage:

i). Copies of the entire blockchain are stored across a network of computers (nodes).

ii). All nodes must agree (reach consensus) on the validity of new blocks.

4. Immutability:

Once data is recorded and the block is added to the chain, it’s very hard to alter without network-wide agreement.

That's all for now 

I hope you learn something new 

Good luck 🫶
