cita v0.20.2 Release Notes

Release Date: 2018-11-27 // over 5 years ago

  • 🛠 Fixed a bug that getting blockhash in solidity contract will get uncertain result.

    pragma solidity ^0.4.24;
contract Test {
    bytes32 public hash;

    function testblockhash() public {
        hash = blockhash(block.number-1);
    }
}

    🚀 Deploy this contract, then send transaction to call testblockhash. Once one of the nodes receives the transaction, the chain will stop growing.
