The last main category of blockchain features is directly related to the fact that the entire blockchain is replicated to every full blockchain node. Every full node can see the entire blockchain, providing unparalleled transparency. Although data stored in blocks is commonly encrypted, the data itself is available to any user of any node. If the data is unencrypted, anyone with access to a node can see it. If it is encrypted, a user with the proper decryption key(s) can access blockchain data from any node and then be able to decrypt it.

Blockchain transparency makes it possible to trust the integrity of the data. Any node can (and does) routinely verify the integrity of each block and, therefore, the entire blockchain. Any modifications to the “immutable” blockchain data become immediately evident and easy to fix.
