摘要

本文定义了一组 Provider 方法，这些方法用来定义 DApp (Decentralized Application) 如何与 CKB 区块链的节点之间进行交互。

为防止不同的 Provider 定义不同的方法名称，导致定义和交互方式的碎片化，我们希望通过这个文档定义一组通用的 Provider 方法。

ckb-rich-node RPC base on ckb-rpc and ckb-indexer-rpc.

Both RPCs are JSON-RPC protocol, more information can refer to ckb-rich-node.

	contract D {

	function delegatecallSetN(address _e, uint _n) public {
	_e.delegatecall(bytes4(keccak256("setN(uint256)")), _n); // D's storage is set, E is not modified
	}
	}
