Private network API methods

:::caution Important

  • This reference contains API methods that apply to only private networks. For API methods that apply to both private and public networks, see the public network API reference.
  • All JSON-RPC HTTP examples use the default host and port endpoint http://127.0.0.1:8545. If using the --rpc-http-host or --rpc-http-port options, update the endpoint.

:::

CLIQUE methods

The CLIQUE API methods provide access to the Clique consensus engine.

:::note

The CLIQUE API methods are not enabled by default for JSON-RPC. To enable the CLIQUE API methods use the --rpc-http-api or --rpc-ws-api options.

EEA methods

The EEA API methods provide functionality for private transactions and privacy groups.

:::note

The EEA API methods are not enabled by default for JSON-RPC. To enable the EEA API methods, use the --rpc-http-api or --rpc-ws-api options.

:::

eea_sendRawTransaction

Distributes the private transaction, generates the privacy marker transaction and submits it to the transaction pool, and returns the transaction hash of the privacy marker transaction.

The signed transaction passed as an input parameter includes the privateFrom, privateFor or privacyGroupId, and restriction fields.

The gas and gasPrice are used by the privacy marker transaction not the private transaction itself.

To avoid exposing your private key, create signed transactions offline and send the signed transaction data using eea_sendRawTransaction.

:::important

For production systems requiring private transactions, use a network with a consensus mechanism supporting transaction finality to make sure the private state does not become inconsistent with the chain. For example, IBFT 2.0 and QBFT provide the required finality.

Using private transactions with fast sync isn't supported.

:::

Parameters

transaction: string - signed RLP-encoded private transaction

Returns

result: string - 32-byte transaction hash of the privacy marker transaction

:::tip

If creating a contract, use priv_getTransactionReceipt to retrieve the contract address after the transaction is finalized.

:::

PRIV methods

The PRIV API methods provide functionality for private transactions and privacy groups.

:::note

The PRIV API methods are not enabled by default for JSON-RPC. To enable the PRIV API methods, use the --rpc-http-api or --rpc-ws-api options.

:::

priv_call

Invokes a private contract function locally and does not change the privacy group state.

For private contracts, priv_call is the same as eth_call for public contracts.

Parameters

  • privacyGroupId: string - 32-byte privacy Group ID

  • call: object - transaction call object

  • blockNumber: string - hexadecimal or decimal integer representing a block number, or one of the string tags latest, earliest, pending, finalized, or safe, as described in block parameter

    :::note pending returns the same value as latest. :::

Returns

result: data - return value of the executed contract

}

priv_getEeaTransactionCount

Returns the private transaction count for the specified account and group of sender and recipients.

::caution important If sending more than one transaction to be mined in the same block (that is, you are not waiting for the transaction receipt), you must calculate the private transaction nonce outside Besu instead of using priv_getEeaTransactionCount. :::

Parameters

  • address: string - account address

  • sender: string - base64-encoded Tessera address of the sender

  • recipients: array of strings - base64-encoded Tessera addresses of recipients

Returns

priv_getFilterChanges

Polls the specified filter for a private contract and returns an array of changes that have occurred since the last poll.

Filters for private contracts can only be created by priv_newFilter so unlike eth_getFilterChanges, priv_getFilterChanges always returns an array of log objects or an empty list.

Parameters

  • privacyGroupId: string - 32-byte privacy Group ID

  • filterId: string - filter ID

Returns

result: array of objects - list of log objects, or an empty list if nothing has changed since the last poll

priv_getFilterLogs

Returns an array of logs for the specified filter for a private contract.

For private contracts, priv_getFilterLogs is the same as eth_getFilterLogs for public contracts except there's no automatic log bloom caching for private contracts.

:::note

priv_getFilterLogs is only used for filters created with priv_newFilter. To specify a filter object and get logs without creating a filter, use priv_getLogs.

priv_getTransactionCount

Returns the private transaction count for specified account and privacy group.

:::important

If sending more than one transaction to be mined in the same block (that is, you are not waiting for the transaction receipt), you must calculate the private transaction nonce outside Besu instead of using priv_getTransactionCount.

:::

Parameters

  • address: string - account address

  • privacyGroupId: string - privacy group ID

Returns

result: string - integer representing the number of private transactions sent from the address to the specified privacy group

priv_newFilter

Creates a log filter for a private contract. To poll for logs associated with the created filter, use priv_getFilterChanges. To get all logs associated with the filter, use priv_getFilterLogs.

For private contracts, priv_newFilter is the same as eth_newFilter for public contracts.

Parameters

:::note

fromBlock and toBlock in the filter options object default to latest.

:::

Returns

result: string - filter ID

priv_uninstallFilter

Uninstalls a filter for a private contract with the specified ID. When a filter is no longer required, call this method.

Filters time out when not requested by priv_getFilterChanges or priv_getFilterLogs for 10 minutes.

For private contracts, priv_uninstallFilter is the same as eth_uninstallFilter for public contracts.

Parameters

  • privacyGroupId: string - 32-byte privacy group ID

  • filterId: string - filter ID

Returns

result: boolean - indicates if the filter is successfully uninstalled

qbft_getPendingVotes

Returns votes cast in the current epoch.

Parameters

None

Returns

result: map of strings to booleans - map of account addresses to corresponding boolean values indicating the vote for each account; if true, the vote is to add a validator. If false, the proposal is to remove a validator.

qbft_getSignerMetrics

Provides the following validator metrics for the specified range:

  • Number of blocks from each validator

  • Block number of the last block proposed by each validator (if any proposed in the specified range)

  • All validators present in the last block of the range

Parameters

  • fromBlockNumber: string - hexadecimal or decimal integer representing a block number, or one of the string tags latest, earliest, pending, finalized, or safe, as described in block parameter

  • toBlockNumber: string - hexadecimal or decimal integer representing a block number, or one of the string tags latest, earliest, pending, finalized, or safe, as described in block parameter

:::note pending returns the same value as latest. :::

If you specify:

  • No parameters, the call provides metrics for the last 100 blocks, or all blocks if there are less than 100 blocks.

  • Only the first parameter, the call provides metrics for all blocks from the block specified to the latest block.

Returns

result: array of objects - list of validator objects

:::note

The proposer of the genesis block has address 0x0000000000000000000000000000000000000000.

}

qbft_getValidatorsByBlockNumber

Lists the validators for the specified block.

For all blocks up to the chain head block this method returns the validators that were used at the time the block was produced.

Use blockNumber to get the list of validators for that block.

For the chain head block there are two validator lists associated with it:

  1. The validators that were used at the time the block was produced. This list is returned by passing latest as the input parameter.
  2. The validators that will be used to produce the next block. This list is returned by passing pending as the input parameter.

In most instances the two lists for the chain head block are the same. However, when voting has completed to add or remove a validator, the validators that will be used to produce the next block are different. Comparing the two lists can be helpful when diagnosing a stalled chain.

:::note When the validator list changes, an INFO log message displays, showing the previous list of validators and the new list of validators. :::

Parameters

  • blockNumber: string - hexadecimal or decimal integer representing a block number, or one of the string tags latest, earliest, pending, finalized, or safe, as described in block parameter

Returns

result: array of strings - list of validator addresses
