Private network API methods

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 pruning or 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.

curl -X POST --data '{"jsonrpc":"2.0","method":"eea_sendRawTransaction","params": ["0xf869018203e882520894f17f52151ebef6c7334fad080c5704d77216b732881bc16d674ec80000801ba02da1c48b670996dcb1f447ef9ef00b33033c48a4fe938f420bec3e56bfd24071a062e0aa78a81bf0290afbc3a9d8e9a068e6d74caa66c5e0fa8a46deaae96b0833"], "id":1}' http://127.0.0.1:8545

IBFT 2.0 methods​

Returns​

result: object - private Transaction receipt object, or null if no receipt found

curl -X POST --data '{"jsonrpc":"2.0","method":"priv_getTransactionReceipt","params":["0xf3ab9693ad92e277bf785e1772f29fb1864904bbbe87b0470455ddb082caab9d"],"id":1}' http://127.0.0.1:8545

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

curl -X POST --data '{"jsonrpc": "2.0","method": "priv_newFilter","params": ["4rFldHM792LeP/e2WPkTXZedjwKuTr/KwCFTt6mBbkI=",{"fromBlock": "earliest","toBlock": "latest","addresses": ["0x991cc548c154b2953cc48c02f782e1314097dfbb"],"topics": ["0x85bea11d86cefb165374e0f727bacf21dc2f4ea816493981ecf72dcfb212a410"]}],"id": 1}' http://127.0.0.1:8545

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

curl -X POST --data '{"jsonrpc": "2.0","method": "priv_uninstallFilter","params":["4rFldHM792LeP/e2WPkTXZedjwKuTr/KwCFTt6mBbkI=","0x4a35b92809d73f4f53a2355d62125442"],"id": 1}' http://127.0.0.1:8545

QBFT methods​

The QBFT API methods provide access to the QBFT consensus engine.

note

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

qbft_discardValidatorVote​

Discards a proposal to add or remove a validator with the specified address.

Parameters​

address: string - 20-byte address of proposed validator

Returns​

result: boolean - indicates if the proposal is discarded

curl -X POST --data '{"jsonrpc":"2.0","method":"qbft_discardValidatorVote","params":["0xef1bfb6a12794615c9b0b5a21e6741f01e570185"], "id":1}' http://127.0.0.1:8545

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.

curl -X POST --data '{"jsonrpc":"2.0","method":"qbft_getPendingVotes","params":[], "id":1}' http://127.0.0.1:8545

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.

curl -X POST --data '{"jsonrpc":"2.0","method":"qbft_getSignerMetrics","params":["1", "100"], "id":1}' http://127.0.0.1:8545

qbft_getValidatorsByBlockHash​

Lists the validators defined in the specified block.

Parameters​

block: string - 32-byte block hash

Returns​

result: array of strings - list of validator addresses

curl -X POST --data '{"jsonrpc":"2.0","method":"qbft_getValidatorsByBlockHash","params":["0xbae7d3feafd743343b9a4c578cab5e5d65eb735f6855fb845c00cab356331256"], "id":1}' http://127.0.0.1:8545

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

curl -X POST --data '{"jsonrpc":"2.0","method":"qbft_getValidatorsByBlockNumber","params":["latest"], "id":1}' http://127.0.0.1:8545

qbft_proposeValidatorVote​

Proposes to add or remove a validator with the specified address.

Parameters​

  • address: string - account address

  • proposal: boolean - true to propose adding validator or false to propose removing validator

Returns​

result: boolean - true

curl -X POST --data '{"jsonrpc":"2.0","method":"qbft_proposeValidatorVote","params":["42d4287eac8078828cf5f3486cfe601a275a49a5",true], "id":1}' http://127.0.0.1:8545
