I've forked (mine is not pub to Github Yet ..^^) EthereumJ Poc8 Version about a fews months ago
and not small changes I made on it (Miner, PeerManager, adding pre/post MIne State theories and many).
While I've adding codes on EthereumJ, Golang version Frontier has released and I wonder
EthereumJ's progress and Roadmap. Because I feel like current version of EthereumJ is very
far from Go or cpp versions.
