# Query Account

Request

topio chain queryAccount

Request Parameters

Parameter Name Required Default Value Type Description
account_addr No The default account. String Query specified account. If not specified, query the default account.

Options

Option Name Default Value Type Description
-h, --help - - Check the command's help information.

Response Parameters

Parameters Name Parameter Type Description
account_addr String Normal user account address or contract account address.
available_gas Uint64 The available gas of the account address. The unit is Tgas. If the return value is negative, there may be two reasons: 1. The account balance after obtaining free gas is less than 100*10^6 uTOP; 2. Unlock the TOP Token after running out the gas exchanged.
balance Uint64 The balance of the account address. The unit is uTOP.
burned_token Uint64 All burned TOP tokens of the account address. The unit is uTOP.
cluster_id Uint8 cluster ID.
contract_address List If an application contract is deployed by a ordinary account, the application contract account address will be returned.
created_time Uint64 The clock height when the account created on the blockchain.
disk_staked_token Uint64 The amount of locked TOP tokens to exchange disk. The unit is uTOP.
gas_staked_token Uint64 The amount of locked TOP tokens to exchange gas. The unit is uTOP.
group_id Uint8 group ID.
latest_tx_hash String The hash of the latest successful transaction.
latest_tx_hash_xxhash64 String The xx64hash of the latest successful transaction.
latest_unit_height Uint64 The unit block height of the latest successful transaction.
lock_balance Uint64 Locked TOP tokens used for application contract transactions. Unit of measurement is uTOP When running application contract, the transaction sender can transfer TOP tokens to the contract account at the same time. If the contract fails to execute, the transferred TOP tokens needs to be returned to the sender. Therefore, the transferred money should be locked before running the contract successfully.
lock_deposit_balance Uint64 Application contract transaction costs are related to the CPU time and transaction size. The costs of the application contract transactions cannot be determined at the beginning of the transaction. The method is to lock part of the transaction deposit of the transaction sender. At the third round of consensus of the transaction, according to the final execution of the application contract, the transaction deposit of the sender is deducted to pay for the costs. Measured in uTOP.
lock_gas Uint64 Application contract transaction costs are related to the CPU time and transaction size. The costs of the application contract transactions cannot be determined at the beginning of the transaction. The method adopted is to freeze part of the gas of the transaction sender. At the third round of consensus of the transaction, according to the final execution of the application contract, the gas of the sender is deducted to pay for the costs. Measured in Tgas.
nonce Uint64 The nonce of the latest successful transaction. Unique in the global network.
total_free_gas Uint64 Total free gas of the account address. Measured in Tgas. At present, when the account balance ≥100*10^6 uTOP, the system will give the account 25,000 Tgas for free. This value changes along with the on-chain governance parameters changes.
total_gas Uint64 Total gas of the account address. Measured in Tgas.
total_stake_gas Uint64 Total gas obtained by locking TOP Tokens. Measured in Tgas.
unlock_disk_staked Uint64 TOP tokens to exchange disk in unlock. After initiating the unlock, we need to wait 24 hours for the unlocked amount to arrive in the account.
unlock_gas_staked Uint64 TOP tokens to exchange gas in unlock. After initiating the unlock, we need to wait 24 hours for the unlocked amount to arrive in the account.
unused_vote_amount Uint64 Unused vote amount of the account.
vote_staked_token Uint64 TOP tokens to exchange votes in lock.
zone_id Uint8 zone ID.

Shard to which the account belongs:

ID Shard
zone_id, cluster_id, group_id, are 1, 0, 0 Beacon Network
zone_id, cluster_id, group_id, are 2, 0, 0 Beacon Network
zone_id, cluster_id, group_id, are 14, 1, 1 Archive Network
zone_id, cluster_id, group_id, are 15, 1, 1 Edge Network
zone_id, cluster_id, are 0, 1, group_id∈[1,63] Audit Network
zone_id, cluster_id, are 0, 1, group_id∈[64,126] Validate Network

To query application contract account information, return the following two parameters in addition to the above parameters.

Parameter Name Parameter Name Description
contract_code String Application contract code.
contract_parent_account String Contract parent account that deployed the application contract.

# Query Chain Information

Request

topio chain chainInfo

Request Parameters

None.

Options

Option Name Default Value Type Description
-h,--help - - Check the command's information.

Response Parameters

Parameter Name Parameter Type Description
first_timerblock_hash String Hash of the first clock block.
first_timerblock_stamp Uint64 Generation time of the first clock block.
init_total_locked_token Uint64 Total TOP Token initially locked by the system. The system initializes the exchange rate of gas = total gas/ total locked amount of the system to avoid the system initialized exchange rate of gas to be 0.
token_price Uint64 Exchange rate of locking TOP Token for gas, measured in tgas/top, which changes dynamically with the change of locked TOP token in the system.
total_gas_shard Uint32 Total gas per shard for 24 hours.
validator_group_count Uint32 Number of validator group.
network_activate_time Uint32 Network activate time.

# Check Data Synchronization Status

After the node is successfully connected to the network, TOPIO automatically synchronize the data from the chain to local database. You can run a command to view the data synchronization status of the node.

Request

topio chain syncStatus

Returned Messages

  • full-sync-mode: Full synchronization mode, which will synchronize all data in the network, applicable to edge nodes, exchange nodes, archive nodes, validator nodes and audit nodes. If the progress is 100%, it indicates that the data on the chain has been synchronized. If the synchronization is not completed, please execute the command again later.
  • fast-sync-mode: Fast synchronization mode, which will synchronize the data in previous several full tables in the current network to complete fast synchronization, applicable to validator nodes and audit nodes. If the progress is 100%, it indicates that the data on the chain has been synchronized. If the synchronization is not completed, please execute the command again later.
  • checkpoint-sync-mode: Checkpoint synchronization mode, which will synchronize all data after the trusted hard-coded checkpoint time in the network, applicable to audit nodes. If the progress is 100%, it indicates that the data on the chain has been synchronized. If the synchronization is not completed, please execute the command again later.
  • root-beacon chains: Root beacon chain, which stores all data on the chain.
  • sub-beacon chains: Sub-beacon chains, which store data generated on their respective chains.
  • shard chains: Shard chains are responsible for processing transaction information on the chain and storing transaction data.
  • index: The table ID in the network.
  • cur_height: The height of the synchronized table chain of the current node.
  • max_height: The highest height of the table chain on the neighbour nodes of the current node.
