v0.16.4 Release
=====================================

Mandatory Upgrade

This is a major release of Kevacoin software, upgrade to this release is mandatory due to the hard fork on March 25, 2020. The hard fork will switch the Proof-of-Work hash algorithm from Cryptonight R to RandomKeva.

Before upgrading to this version, make sure to back up your wallet in case something unexpected happens, even though this release should not affect your wallet. Uninstall the previous version and install this version.

Important changes in this release:

- Switch the Proof-of-Work hash algorithm from Cryptonight R to RandomKeva.
- Faster wallet synchronization.

and

Any info about the fork? Algo change, blockchain timing /reward change other changes?
What is the reason for the fork? Which pools will support it? Is it going to be CPU only or also GPU/ASIC?

Dear All,

The mainnet hard fork will be executed at block 46130, at about 14:00 GMT, March 25, 2020. The source code will be released in 48 hours.

The testnet8 will also be live in 48 hours, and its hard fork will be executed at block 6030, at about 14:00 GMT, March 18, 2020.

If you have any questions or concerns, please feel free to let me know. Thank you!

We are communicating with stakeholders, and have made great progress. We have important pieces ready and starting from this week, we will communicate with the rest of the stakeholders and finalize the date. Hopefully, we can let the community know the exact fork date this week. Thank you again for your patience and please stay tuned!

maybe 2020/4/4

So when the hardfork?

This is very good! You won't have to many problems.


Joined. Voted for RandomX because I like CPU coins.

Fortunately, we will be able to do a hard-fork and keep the original chain. So the GPU miners will keep their coins.

The vote will be closed in 48 hours, so act soon!

old chian,new algo

One thing that you can do, to not disappoint the early GPU miners is to premine the existing coins on the new blockchain and swap them for old coins so they won't loose the coins mined. Then  they can continue to mine Keva like other if they want to stick to the project. This is how I would do it, as I think you can't simply switch to new mining algo, but rather launch a new blockchain.

Thanks for the suggestions and I apologize for lack of communication on this important issue. The main reason is that we are still struggling with what is the best move for the next step. We originally plan to use our slightly tweaked version of Cryptnoght R (and call it Cryptonight KV). However, that would require us to submit patches to various miners (e.g. XMRig, XMR-stak, T-rex, etc.). Since CN/R is a GPU/CPU algorithm, we need to implement support AMD, NVIDIA and CPU. It is quite a lot of work and uncertainty (not sure if the miners would accept our patches and they are moving to CPU-only RandomX). Then Kevacoin source code will need lots of changes. Unlike Monero source code, which is designed with hard-forks in mind, the Keva source code does not have support for hard-fork and we need to implement and test it. This is lot of work and testing. Honestly, we are secretly hoping that Nicehash's support for CN/R will go away, just like other older CN algorithms. We had a glimmer of hope this morning as the available hash rate of CN/R dropped to 1MHz (from 6 MHz) on the US market for a while.

However, we do agree that the CPU only is the future, and it fits our targeted developer demography, as these people normally have machines with powerful CPUs but only average GPUs. The recent development of AMD multi-core CPUs also makes CPU mining very promising. Our concern is that some of our early supporters are GPU miners and we don't want to disappoint them. But it is a fact that CPU mining is good for the long term for Kevacoin.

We will have a vote on the switch as suggested. Comments and suggestions are welcomed!

A nicehash/asic,even GPU mining-resistent algo would be better imo. CPU only is the best.
Since I don't like, and is also too centralized the ninja mining/cloud mining all over other projects, this will be the best move for Keva.

Dev, so has it really been decided that there will be an algo change? If so, then when, and to what algo? I think that the community should have a part in these decisions - like if you do decide to switch the algo - you could let the community vote on it. A new / modified algo for KVA would also be cool (assuming that your team is capable of making such, since you plan to develop a blockchain for Key-Value data storage ).

This is a message I posted on Bitcointalk Altcoin forum:

Cryptnight R Price on NiceHash Went Down All the Way

https://bitcointalksearch.org/topic/cryptnight-r-price-on-nicehash-went-down-all-the-way-5228737

It described what happened last night on the NiceHash CN/R marketplace.

I also agreed that who will be authority to manage the community donation fund as they are the person who donates with more clearity.
