Immutable

Short Description:

Immutable refers to the property of a blockchain ledger that makes it resistant to modification or alteration once data has been recorded and confirmed in a block.

Main Description:

Immutable refers to the property of a blockchain ledger that makes it resistant to modification or alteration once data has been recorded and confirmed in a block. Immutability is one of the fundamental characteristics of blockchain technology and plays a crucial role in ensuring the integrity, transparency, and security of the blockchain network.

Once a transaction or piece of data is added to a block and that block is added to the blockchain, it becomes extremely difficult, if not impossible, to change or delete that data. This is because each block in the blockchain contains a cryptographic hash of the previous block, creating a chain of blocks where any alteration in one block would require changing all subsequent blocks, which is computationally infeasible.

It’s important to note that while blockchains are highly immutable, they are not entirely immune to changes or updates. Changes can occur through network upgrades or protocol forks, but these are typically implemented through consensus among network participants and are carefully managed to maintain backward compatibility and trust in the system.
