Not sure if this is related to the issue, but it seems that Parity and Geth have a chain split now on Morden.

I am running Geth v6.0.6 and Parity v2.5.5 (both in a docker container with base image being debian:stretch-slim) on Morden testnet. The block hashes are the same for 4729276, but starting from block 4729277, here's what I got.

Geth

> web3.eth.getBlock(4729277).then(({ hash }) => console.log(hash))
> 0x8d02d003a416243acf173706fba49580974d909b1e8b3d6c58ec4a77c4972ce7

Parity

> web3.eth.getBlock(4729277).then(({ hash }) => console.log(hash))
> 0x67be5907a969faf8634ead6e296be52e3426cd4031be8436a4bdd147f0e9194

4729277 is just several blocks after the scheduled fork block 4729274 on Morden. Is there a consensus issue going on between Geth and Parity now?

@sammy1991106 Thank you for the report!

This is fixed by #14 !

The issue can actually be found here identifying that EIP-684 was missing from the required EIPS.
