The contract does not run, it cannot get enough gas.

Here is the txn -

The gas used us 4712388 which is my gaslimit-1. The contract is simple so we have an issue with genesis I guess. I have two nodes in total and I attached them via addPeer.

~/blockchain$ cat genesis.json { "config": { "chainId": 33, "homesteadBlock": 0, "eip155Block": 0, "eip158Block": 0 }, "nonce": "0x0000000000000033", "timestamp": "0x0", "parentHash": "0x0000000000000000000000000000000000000000000000000000000000000000", "gasLimit": "0x47e7c5", "difficulty": "0x100", "mixhash": "0x0000000000000000000000000000000000000000000000000000000000000000", "coinbase": "0x3333333333333333333333333333333333333333", "alloc": {} }

Contract -

pragma solidity ^0.4.18;

contract RegisterContract {

    uint public contractWeight;
    mapping(bytes32=>string) public contracts;

    function addContract ( string jsonInput, bytes32 hashKey) public {

        contracts[hashKey] = jsonInput;


    function addWeight (uint weight) public {
        contractWeight = weight;


  • I found out it is the string that is causing the problem. – Trevor Oakley Mar 31 at 5:48
