How Blockchain technology is not editable?
Blockchain technology is designed to be immutable or unchangeable. This is achieved through a combination of cryptographic algorithms and distributed consensus mechanisms.
Each block in a blockchain contains a unique cryptographic hash, which is a mathematical function that produces a fixed-length string of characters that uniquely identifies the block. The hash of each block also includes the hash of the previous block in the chain, which creates a secure and tamper-proof link between the blocks.
If someone were to try to change the data in a block, the hash of that block would also change, which would invalidate the hash of the subsequent blocks in the chain. As a result, the entire chain would be broken, and the tampering would be immediately detectable.
Moreover, because blockchain technology relies on a distributed network of nodes that all validate transactions and store a copy of the blockchain, changing the data in one block would require changing the data on every copy of the blockchain held by each node. This is practically impossible and would require an enormous amount of computing power.
In summary, blockchain technology is designed to be immutable through the use of cryptographic hashing, distributed consensus mechanisms, and decentralized networks of nodes.
