Genesis with aura setup

[blazejkrzak]

As a developer
I should be able to setup an aura consensus
Within genesis.json file
So I should implement parser and tests for that, and compare it against parity block

Mentioned in:
https://openethereum.github.io/wiki/Demo-PoA-tutorial
goerli#31

Tools to use:
rlpdump

[blazejkrzak]

Imho it can be split onto smaller issues

[blazejkrzak]

• transcode it to genesis.json file that match 1:1

[blazejkrzak]

eth.getBlock("0") could solve the issue.
Outcome was pushed into https://github.com/lukso-network/go-ethereum/tree/feature/11/basic-tests-against-goerli-aura

[mxmar]

• Parser works
• Tests are passing
• Tested parity and geth configs separatly
• Connection to L15 test network with parity client and config with timestamp="0x0"

Connected to L15 from localhost by:
./openethereum --config parity.toml

I've changed backend to generate Seal config like:

"seal": {
      "authorityRound": {
        "step": "0x0",
        "signature": "0x0000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000"
      }
    },

So the parity-spec.json looks like:

          ]
        }
      }
    }
  },
