JSON-RPC API

This document highlights all the details regarding ela json rpc interfaces. It follows json-rpc 2.0 protocol but also remains compatible with version 1.0. This that means both named and positional params are acceptable.

"id" is optional, which will be sent back in the result samely if you add it in a request - it's needed when you want to distinguish between different requests.

"jsonrpc" is optional and tells which version this request uses. In version 2.0, it's required, while in version 1.0, it doesn't exist.

getbestblockhash

Return the hash of the most recent block

result:

name	type	description
blockhash	string	the hash of the most recent block

  "params": [],
  "id": 1
}

Response:
