Blockchain ááá¯áá²á· áá¬áááºá áááºááá¬áá¬áá²? ð€
Itâs simple. It comes from combining Block (the boxes) and Chain (the connection).

ðŠ Block (The Box)
Transaction data is collected and stored together as a single "Block." Once a block is full, it gets locked and sealed.

ð Chain
Here is the interesting part. Every time a new block is created, it includes the unique "fingerprint" (Hash) of the previous block. This causes the blocks to link

The block's "fingerprint" will change. Because of this, every subsequent block connected to it will become invalid. The entire network will immediately realize, "Hey! Someone is tampering with the records!"

That is why it is almost impossible to re-edit records that have already arrived on the Blockchain.
