JSON-RPC

JSON is a lightweight data-interchange format. It can represent numbers, strings, ordered sequences of values, and collections of name/value pairs.

JSON-RPC is a stateless, light-weight remote procedure call (RPC) protocol. Primarily this specification defines several data structures and the rules around their processing. It is transport agnostic in that the concepts can be used within the same process, over sockets, over HTTP, or in many various message passing environments. It uses JSON (RFC 4627) as data format.

JavaScript API#

To talk to an platon node from inside a JavaScript application use the web3.js library, which gives an convenient interface for the RPC methods.

Note#

After upgrading to version 1.1.1, PlatON has extended JSON-RPC 2.0 through Ethereum Compatible to extend JSON-RPC 2.0 to request The request object adds bech32 field, Booleans type. If bech32 is true, it means that the codec format of the address part in this rpc call is bech32, and the default is EIP55. And it supports Ethereum's RPC call, Reference.

The following just shows the RPC call process with curl procedure. Actually you need to make some adjustments according to the specific situation of your server. For example, a possible call procedure for PlatON is curl -X POST -H 'content-type: application/json' --data '{"jsonrpc":"2.0","bech32":true,"method":"web3_clientVersion","params":[],"id":67}' 127.0.0.1:6789.

JSON RPC API Reference#

admin_startWS#

The startWS administrative method starts an WebSocket based JSON RPC API webserver to handle client requests.

Parameters#

All the parameters are optional:

cors: cross-origin resource sharing header to use (defaults to "")
apis: API modules to offer over this interface (defaults to "platon,net,web3")

Returns#

Boolean - The method returns a boolean flag specifying whether the WebSocket RPC listener was opened or not. Please note, only one WebSocket endpoint is allowed to be active at any time.

Example#

// Requestcurl -X POST --data '{"jsonrpc":"2.0","bech32":true,"method":"admin_startWS","params":[host, port, cors, apis],"id":1}'

debug_getWaitSlashingNodeList#

Get all nodes with zero production blocks, and a list of nodes that have been observed because of zero production blocks.

Parameters#

Returns#

array - The node list of the zero production block, each structure contains three fields, NodeId: the node ID of the zero production block, Round: the number of consensus rounds in the first zero production during the observation period, CountBit: the zero production block Bitmap of the number of times (starting from Round, 1 means that no block is produced in this round).

Example#

// Requestcurl -X POST --data '{ "jsonrpc": "2.0", "method": "debug_getWaitSlashingNodeList", "params": [], "id": 74}'// Result{  "id": 74,  "jsonrpc": "2.0",  "result": "[{    "NodeId": "8e91f562c1798dc8c567a5c4a99a840eb86e43324b622fd0a4a8defdf873baf8f822313d7f35227fe15b6f4a2767dfb9ea7f7968d0a3a243e57b4d1090f6fc6c",    "Round": 1000,    "CountBit": 7  }]"}

debug_getValidatorByBlockNumber#

Get the list of validators of the specified consensus round, pass in any block height in a consensus round, the system will automatically calculate the consensus round to which the block height belongs and return the list of validators of that consensus round, or return the empty string if there is no data.

Parameters#

Uint64 - blockNumber

Returns#

array - Validator List, Address: address of node; NodeId：id of node；BlsPubKey：bls public key of node.

Example#

// Requestcurl -X POST --data '{ "jsonrpc": "2.0", "method": "debug_getValidatorByBlockNumber", "params": [1000], "id": 75}'// Result{  "jsonrpc": "2.0",  "id": 75,  "result": "[{    "Address": "0xc6a99e99978ac78333897e2117ec9747f010b827",    "NodeId": "2d016c3c2dd0ffb4c251940e255a90cd4541c553710c0b5b594595d1eaa660cb8109c1cd90ac864665852abffc7fd47343b03d0156d81501b838be7c4e354d6d",    "BlsPubKey": "21a9fc05c3b349e9a50f0966d5c338082f52e72639778d6ed5d11ce544efc2ba8b8f463d03eb4d02934937da603d0f109a08e5c4c82c835fc7f4209ad0d5c551853dd9fbfab08345346696e09124c19e0d08e01a4b5d841eea896fd3ae982995"  }]"}
