Looks like it did not solve the problem, ah, still the four addresses in the mining

Hi all!
I offer you an anti-attack patch for this coin.

If you want to stop the 51% attack on EAC, use the patched wallet.
The patch is an added checkpoint in order to disconnect the attackers fork. With this patch, everyone should be able mining this coin.

I you prefer building from the source: https://github.com/Sandokaaan/earthcoin/
...or use my builds below.

"confirmations" : -1 = orphaned

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...

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 

Any new momentum on this coin?

any good pool??

Earthcoin is a coin, a statement, Which symbolizes a common hope for the future climate. Earthcoin originates from a desire to visualize Our attitude and willingness to change. Earthcoin is continuously numbered,  so each Simple coin is a unique and personal jewelery.

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 remember the good old days, when everyone thought EAC is a genuine project and there was so much community buzzz around it. Ah well...

EAC added to http://coincave.nl miningpool.

you can check in
but you can not check out

^ This is indeed true. However now that Japan, India, Aus, Other are taking leads - new exchanges will populate them all more instead

China is the name of the game in cryptoworld in general. They have huge demand for amongst other things Bitcoin. If China were to be for some reason cut out of the Equation most cryptocurrencies would tank hard.

Volume is rather huge on the Chinese exchanges, and NovaExchange is starting to capitalize on it - If you belong to other big exchanges please ask them to host EARTHCOIN, we will gladly put up coins at each exchange to get it going..

Another nice climb is happening and it looks like we're being blessed by China again in the near .

Have a look: https://www.btc123.com/market?symbol=btc38eaccny

Out of maintenance now - deposit/withdrawal addresses working fine .

Great time to grab some as all the popular alts start to climb again.

ALREADY ITS UNDER MAINTENENCE...

The party is over. Now dump.

Looks like EAC is sexy again  

I don't get the problem with the wallet ? I use the 1.3.2 version, synchronizing well for the moment.

Something has to be done for the official website and the calendar countdown page, i'm not going to give a lecture about the many reasons that make those tools mandatory for the sake of this coin you guys get the point.

Just registered on nova, still giving away some EAC ?

Cheers

Purchases and withdrawals working fine...

Who is carrying out 51% attack, is it possible to fix it?
