Immutabile

When we talk about something being "immutable" in the blockchain world, we’re essentially saying that once data is written, it’s set in stone—no one can change it, not even the person who created it. This is a big deal because it means that blockchain records are incredibly trustworthy. Imagine trying to rewrite history books without anyone noticing—it’s kind of like that. The blockchain achieves this immutability through cryptographic hashing, a process that links each block of data to the previous one in a way that makes tampering with any part of the chain virtually impossible.

Each block in a blockchain contains a hash, which is like a unique fingerprint created from the data in that block and the hash of the previous block. This forms a chain that’s incredibly secure because if anyone tries to alter a single block, the hash would change, breaking the chain and signaling that something’s wrong. This property of immutability is what makes blockchain so reliable, especially for applications where data integrity is crucial, like in cryptocurrencies or smart contracts.
