re: I don't quite get one part: from your example, only the hash of the data is stored in the blockchain; isn't the data supposed to be decrypted later...

well hash defines a unique signature of a block, in real practice, the block also contains an index value, a data(record of transactions), a timestamp , and also the golden nonce value.The cryptographic hash dont account for decryption. Its like the address part of a data-structure, and the data is stored in the data part of the data-structure.
