In the previous chapter, we mainly described the block chain, block, mining and so on, set the data format of the block, realize how to encrypt the block into the block chain to ensure the effectiveness of the block chain, and we also through the design of a data problem, It is necessary to have a certain computational power (PoW) to prove that a block is a new block in the block chain. In this chapter, we will implement the following features 1. Create a simple

Transparent data encryption (Transparent encryption)TDE-column-based encryptionWith Oracle's tde-column-based encryption, all you have to do is define the columns that need to be encrypted, Oracle creates a private security encryption key for the table that contains the encrypted columns, and then encrypts the plaintext data for the specified column with the encryption algorithm that you specify. This encryption, does not require us to write special code, as long as we make "need to encrypt the
