EarthCoin (EAC), one of the "classic" altcoins that has been here since 2013, was controled by a group of hackers for several months, who did not let anyone else mining this coin. Any attempt to extract a block of this coin failed up to now - all the blocks found by someone other were promptly orphaned. The original EarthCoin developer team did nothing to stop this mining monopoly, so we have decided to take the initiative and get this coin out of the clutches of those evil miners.

We have made the necessary changes to the source code and created a new network in which anyone can freely extract EarthCoin blocks. The party is now coming to the end. To follow this new, liberated EarthCoin, start using the new version of EAC wallet.

Primary announcement of the EarthCoin can be found here https://bitcointalk.org/index.php?topic=379236.0
EarthCoin is listed on coinmarketcap https://coinmarketcap.com/currencies/earthcoin/

Instructions for *.conf file:
The file earthcoin.conf is not required, unless you need RPC functions. It should be located in c:\Users\[YOUR_WINDOWS_USER_NAME]\AppData\Roaming\EarthCoin\ on a Windows machine or ~/.earthcoin/ on Linux. If you need the earthcoin.conf file, please make sure to include the line port=35677. Wallet should detect nodes automatically from hard-coded seeds, but you can add some nodes manually:
addnode=212.237.21.74:35677
addnode=80.211.198.20:35677
addnode=212.237.21.74:35677
addnode=24.101.122.52:35677
addnode=83.162.30.19:35677
For more nodes see the block explorer.

Build v.2.0.1 for Mac OSX tested on a real Mac machine.
Full sync from a scratch within 9 hours.
An issue to be fixed: package is shown with Litecoin icon, runtime icon is correct.

Updated info on explorers and API

The primary block explorer now operate on the upgraded node:
https://chainz.cryptoid.info/eac/#!crypto

The backup block explorer now supports some new API calls, see:
http://explorer.eacpool.com/info

There is also a rest API integrated in the new wallet code, it can be enabled by adding the line
into the wallet config file. For usage of the rest API see documentation at:
https://github.com/Sandokaaan/EarthCoin2019/blob/master/doc/REST-interface.md

Explorer/API at http://api.deveac.com/ based on my code https://github.com/Sandokaaan/EarthCoin-API
is still broken due to some incompatibilities.

OSX version:
https://github.com/Sandokaaan/EarthCoin2019/releases/download/v.2.0.1/Earthcoin-Core.dmg

I need someone test it (my Mac is dead)...

OSX version re-uploaded, please, test it again
https://github.com/Sandokaaan/EarthCoin2019/releases/download/v.2.0.1/Earthcoin-Core.dmg

Binary build for Mac OSX uploaded. Need to be tested by a Mac user...

3 blocks mined as a mining-pool test on a upgraded node. EAC address eVfUbHXum5NTPZ7LQaqyH27FjyfEJ9vmA8

Accepted on both type of nodes, upgraded as well as legacy.

Binary builds for Windows 32/64 bit uploaded.

Hello all here!

The upgraded code for EarthCoin (v.2.0) is ready:
https://github.com/Sandokaaan/EarthCoin2019

todo:
- upload binary builds
- do some user-side reviews and tests
- notify exchanges and block explorer operators to upgrade their nodes
- upgrade mining pools
- perform the softfork and disconnect nodes that reject to upgrade

New features included in version 2.0:
- security improvements based on the latest bitcoin/litecoin source codes
- fast sync from the scratch (headers first method)
- HD addresses
- simple and safe upgrade from a legacy wallet
- ready for segwit transactions
- possibility of recovery from a stuck without whole blockchain resync
- and many others I don't even know about 

If you are interested, feel free to test the new code.

I registered the domain name deveac.com

Now a temporary backup of newEarthCoin site is avaiable on the address
http://bck.deveac.com/

API block explorer is on address
http://api.deveac.com/

Some links at the old site are probably broken and so should be updated. I will also update the content of the site, it was time 
Email contacts at the newearthcoin.com domain are permanently lost, please do not use them any more.
For the time being, please use the personal message at bitcointalk.org, if you need to contact me. A new mail server will be ready within a week.

Site is not down.
http://80.211.222.88
Only the domain name expired due to the fault of the domain registerer 

Auto-renewal of domain name was purchased however the registerer let the domain name expire. Now they require nearly tenfold higher fee for domain name re-registration. It's a thiefing! Do not bielive the namecheap.com company! They are cheap only for the first billing period 

Now I must find another (a more credible) domain name registrator, maybe chose another domain name...

New version of EartCoin Wallet - upgrade to v1.5.5
Mandatory for mining pools. Since January 1, 2019 block extracted using version prion 1.5.3 will probably be rejected.
Source code: https://github.com/Sandokaaan/earthcoin/releases/tag/v1.5.5
Binary prebuild versions for Windows and Mac OSX will be avaiable later.

This upgrade is designed to solve an incorrect timestamp stuck observed on some nodes, including the block explorer
https://chainz.cryptoid.info/eac/
I also paid the hosting fee on cryptoid.info for next 3 months...

If your node is stuck out of sync, please use the new version 1.5.5. It should recognize the main chain based on checkpoints and improved algorithm for a fork recovery.

Works on version 1.6.0 to remove the obsolete parts of code continue and will be released soon.

OK, maybe a false alert...
Is there someone who lost sync, too?

I operate 6 nodes to support EAC network and there are 3 different block heights on them.

Compare the block heights on teh block explorers

https://chainz.cryptoid.info/eac/
http://explorer.newearthcoin.com/
http://212.237.21.74:3000/
http://120.79.171.136:3000/

I identified the source of the disruption as so called "time travel attack". One of mining pool has adjusted system time to +10 minutes, so the blocks mined by this pool (that one with the EAC address epQSyjK3XyJVEEk1xwuxekrbzty92jynSF) decreases the difficulty. This leads to an increased count of blocks extracted per hour without increasing of the difficulty. Some of nodes do not accept such a manipulated blocks so they lost sync.

My suggestion is accept the block height from the primary explorer https://chainz.cryptoid.info/eac/
and do a softfork from this checkpoint.
But for an action I need the agreement from the comunity.
