blockchain - Geth 私有网络在执行简单合约时返回错误“invalid opcode: SELFBALANCE”
问题描述
我设置了一个简单的 Geth (v1.10.2-stable-97d11b01) 专用网络(genesis.json
下面的配置)。我编译并部署了这个简单的测试合约(solidity 版本:0.8.4+commit.c7e474f2.Emscripten.clang):
// SPDX-License-Identifier: UNLICENSED;
pragma solidity >=0.8;
contract CoinA {
bytes32 public coinName = "FAKE";
mapping (address => uint) public balances;
function transfer(address receiver, uint amount) public {
require(balances[msg.sender] >= amount, "Not enough amount");
balances[msg.sender] -= amount;
balances[receiver] += amount;
}
function set(uint amount) public {
require(amount >= 0);
balances[msg.sender] = amount;
}
function get() view public returns (uint) {
return balances[msg.sender];
}
}
但是,在调用该set
方法时,我收到此错误:
UnhandledPromiseRejectionWarning:错误:返回错误:无效操作码:SELFBALANCE
请就如何解决此问题提出建议。是因为服务器没有支持该操作码的最新功能吗?无论如何我可以在不使用该操作码的情况下编译代码吗?
如果相关,我在 Node 上使用 Web3JS 调用它:
async function setCoin() {
const contract = new w3.eth.Contract(abi, coinAddr);
const query = contract.methods.set(1000);
const tx: TransactionConfig = {
data: query.encodeABI(),
from: accPublicKey,
};
const gas = await w3.eth.estimateGas(tx);
console.log("Estimate Gas: " + gas);
tx.gas = gas;
const signedTx = await w3.eth.accounts.signTransaction(tx, accPrivateKey);
const result = await w3.eth.sendSignedTransaction(signedTx.rawTransaction);
console.log("Done. Gas used: " + result.gasUsed);
}
genesis.json
