What is blockchain wallet

A blockchain wallet (cold wallet) is equivalent to an account on the blockchain and is used to operate transactions on blockchain.
All blockchain transactions will be confirmed by the block and transaction history cannot be changed.
The assets in the block wallet can be transferred to other wallet addresses, or transferred to the escrow for entrusted management.
It is impossible to directly transfer to usable. It needs to be transferred to the escrow wallet in advance and then to usable.
Blockchain wallet is not generated automatically after account registration and it is not fixed. Users need to create a new blockchain wallet after successful registration, or bind with an existing blockchain wallet.
An account can create multiple blockchain wallets, and interchange different blockchain wallets by binding different mnemonics.
Each blockchain wallet has a set of secret keys (12 mnemonic words) composed of 12 English words.
The 12 mnemonic phrase is the key to bin the blockchain wallet and gain access to use the assets in the wallet. It is a highly private information and should not be exposed.
