Dev could you please take a look at the code. I have added EAC to my pool yesterday, over 100 blocks have been initially found, but not 1 single block gets confirmed. If I check the debug.log I see blocks getting reorganised all the time, so something or someone is changing the blockchain. My client is version 1.3.4 freshly compiled from source, blockheight is the same as
https://chainz.cryptoid.info/eac/# . EAC is the only coin on my pool with these kind of issues. I will be taking EAC offline until this has been resolved.
I tried to mine this coin with hashrate from 100M to 10G but every mined block was later orphaned. My last try:
2017-08-10 06:14:48 received block 156e65558960facb2996124ff3344f7c9b7c43644c4b41ab2971520297f32762

It seems someone took full control over this coin

This coin could be mined only by 4 miners to following addresses:
- ek2ukbyBD4gKqx6jHAmFU31Sm5UN9YmfGC
- eS3FErWMAiAtQU2befDtJBXDVdbDN8y2Ed
- eXR5ELqLXKPg7Tfcx2ueZbXWHPJ8h7rGdQ
- efG4K4nLo3pbdxTNmfnjYKYM66jvpXhUZw
Those miners are probably controlled by one person (maybe by the author of this coin himself). And it seems that they accept only blocks mined by one of them. No matter how much hashpower will use any other miner, those 4 miner will automatically increase hashpower to defeat him.
According my estimation, at the current EAC price, the attacker thus gains 50 - 150 $ per hour, so it is his best paid job ever for him.
However, for the EAC, this is a path to the death...
