1  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN][KUMA] Kumacoin LAUNCHING 2014/04/28 15:00 GMT on: August 08, 2020, 02:58:55 PM
Important notification!

Hello, all users.
Kumacoin faces a big fork problem again.
The fork starts at 3069661 and there is an A chain and a B chain.

Code:
A: 6b5881bfa0d4252bba6bf0db67a96853be88e4d1d02caea8eba4147a9da821ef
B: 04e4abb0d2ba8472ac4e304e296bb99d58f44f6482c312648baec93ac17802b0

This problem is caused by a PoS bug that has been occurring since 2019/4 but fixed already.
The root of it is old PoS miner that is still staking with huge hash power.
We solve this fork by hard fork from 3086001 on B chain, don't accept block's version 4 or lower.

So...
All users are required client soft update in a few days!!!
https://github.com/kumacoinproject/kumacoin/releases/tag/v0.8.9.9

Sorry for the short notice.

Warning: Kumacoin is now on big fork problem!

Hello, all users.
Kumacoin forked to many branches because of Staking bugs since 3/29.
We are now fixing bugs and fixed some bug,
please update client!
but you may need to update again.

We found 4 pools, but we can contact with only one pool MiningBeaver.
You MUST be aware of losing coins if you do mining Kumacoin,
we recommend use the pool if you want to do.

Get the latest information from Discord!
Almost all users speak in Japanese because it is a coin developed in Japan.
So many users who can not read English, and they are confused,
they may not be able to respond to questions.

I have updated the Kumacoin Wallet.
Please change to the latest version in the 90000 block within.

I fixed a phenomenon that PoS difficulty becomes abnormally large in conjunction with the PoW difficulty.
