Is blockchain secure? Once a block is added to the end of the blockchain, it is very difficult to go back and change the content of the block. Because each block contains its own hash and the hash of the block before it. Hash codes are created by a mathematical function (hash function).

Blockchain networks use consensus mechanisms (like Proof of Work or Proof of Stake) to agree on the state of the blockchain.

In many blockchains, like Bitcoin, adding a new block requires a proof of work, which involves solving a computationally intensive puzzle.

Once a block is added to the blockchain, changing its content would alter its hash.

This is because each block contains its own unique hash, generated by a cryptographic hash function, along with the hash of the previous block.

it becomes extremely difficult to alter the contents of that block or any previous blocks.

It secures the blockchain's ego because people cannot easily change the blockchain's history or falsify information.

Overall, the combination of cryptographic hashing and decentralization makes blockchain a highly secure technology for recording and verifying transactions.

This is because each block contains a cryptographic hash of the previous block's header, creating a chain of blocks that are linked together
