Data Model - Blockchain as a Service - Alibaba Cloud Documentation Center

In JS SDK, many data structures are consistent with those of the contract platform, including accounts, contracts, blocks, transactions, and receipts.

Account model

Basic account parameters are described as follows:

Name	Type	Description
identity	string	The identity of the account. It is a hexadecimal string.
balance	BigNumber. It is a special type. For more information, see Details	The balance.
auth_map	string	The public key and weight value of an account or a smart contract.
recover_key	string	The recovery public key that is used when the private key is lost. It is a hexadecimal string.
recover_time	number	The last recovery time.
status	number	The status of the account. 0: NORMAL. 1: FREEZE. 2: RECOVERING.
encryption_key	string	The public key that is used to encrypt the transaction amount in a smart contract. It is a hexadecimal string.
