Data Model

Last Updated: May 24, 2019

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.

number number The block number.
parent_hash string The previous block hash.
transaction_root string The root node hash of the Merkle tree generated by the transactions in the block body.
receipt_root string The root node hash of the Merkle tree generated by the receipts in the block body.
state_root string The root node hash of the Merkle tree in the world state.
gas_used number The total gas consumed by transactions.
timestamp number The timestamp.
log_bloom string The log bloom filter.
  • Basic parameters of block_body are described as follows:
Name Type Description
transaction_list Array The transaction list.
