Nyancoin is now KatKoyn.
https://bitcointalksearch.org/topic/annkat-katkoyn-core-v24-released-previously-nyancoin-5445390

The upgrade to AuxPow is completed. AuxPow is active from block height 4574574, which occurred at about 14:32 on 11 January 2023.

All versions v2.2 and below will NOT connect to the main network, currently only v2.3 is supported.

If you are still running an older version, please upgrade to v2.3 - this only involves replacing the binary. Blockchain files, wallet and others are all compatible. All files here: https://github.com/nyancoin-official/nyancoin-client/releases

For v1.x upgrading is still possible, however this will involve reindexing the blockchain files. This will happen automatically but is likely to take several hours.

Note that mining against a version v2.2 and older will create an unsupported fork, and anything on that fork will not exist on the main chain. Currently all major mining pools are on v2.3 other than gigahash.net and pool.scrypt.ovh/nyan/public/ - if you are using those please move to another pool.

These pools are suggested:
https://merged1.cminors-pool.com/
https://yiimp.mastermining.net
https://luckydogpool.com/
https://pools.win/
https://www.0769.it/
https://miningmypool.com/

Others exist and can be used but please ensure they are using v2.3 and that they are on the correct chain. https://miningpoolstats.stream/nyancoin

For trading, please use https://txbit.io/Trade/NYAN/USDT
or AtomicDex (currently desktop and beta/testing mobile wallets only)

As always, make backups of wallet.dat regularly and keep at least one copy on a physically separate device.

One week remaining

For anyone who hasn't upgraded to v2.3 yet, the new version will disconnect older version peers starting on 11 January 2023 assuming mining is consistent until then.

Please upgrade before then to ensure you can remain connected to the network.


It's still possible to upgrade after that date, however doing so will mean some disruption and in some cases reindexing your blockchain files.
It's far simpler and faster to upgrade before, as that only involves replacing the binary file.

If you are compiling from source, you can compile the new version while the other is still running, then just stop the old version, replace with the new binary and restart immediately.

Nyancoin Core v2.3 now available (28 December 2022)

v2.3 will disconnect earlier versions to ensure proper compatibility with AuxPow. It is therefore essential that you upgrade to v2.3 as soon as possible.

Wallet and blockchain files are compatible, no other changes are required other than replacing nyancoind or nyancoin-qt

Source code and binaries for most operating systems here: https://github.com/nyancoin-official/nyancoin-client/releases/tag/v2.3

AuxPow version v2.2 now available, please upgrade.

https://github.com/nyancoin-official/nyancoin-client/releases/tag/v2.2

Due to several problems with the recently released AuxPow versions, please continue to use v2.0 until notified otherwise.
https://github.com/nyancoin-official/nyancoin-client/releases/tag/v2.0

If you have installed v2.1.1 or v2.1.2 please replace with v2.0, as those versions are not likely to continue working properly or at all.

Hey,

Someone posted one here:

https://www.reddit.com/r/nyancoins/comments/x0s0tw/hey_nyans/

Any faucet for NYAN?

Got a full time Dev indeed. Hence why v2.0 was released. Now currently testing AuxPow for Nyancoin.

Most interaction is on Telegram:

The best possible outcome for Nyancoin is if the Nyan Cat creator once again publicly endorses this project.

*Nyancoin was formally licensed back in 2014* 

While very far from a guarantee, such an endorsement is possible if Nyancoin is handled in a trustworthy manner.

Either way, expect marketing spend after AuxPow is secured.

Currently there is no new awareness of this offical Nyan Cat coin.

The Original Nyan Cat YouTube video still gets over 100,000 views a week:

The Official original Nyan Cat NFT sold for 300 ETH and an official collection is doing quite well:

There is a lot of emotional and financial interest in Nyan Cat.

It does represent 2011 peak internet after all.

Maybe if the creator ever gets involved again, a large fund of Nyancoin can be offered for sale in a campaign where 100% of the proceeds would go to charity or a real good cause.

This way, even if interest in Nyancoin does not pick up, the money went somewhere noble and not insider pockets. The process of the money being put to work could be filmed and documented for the public to engage with.

If on the other hand, interest in Nyancoin/ Nyan Cat NFTs from such a campaign increases, well then its well deserved.

 

New exchange, it's just that so far Nyancoin doesn't have a good community and trading volume, It can even be said to be near death. Due to the very small trading volume. Does Nyancoin still have a development team and have future targets for achievement?

Nyancoin once again tracked on CoinMarketCap, Binance, CoinBase, CoinGecko, Crypto.com and the others

This Kitteh still has a few lives left it seems.

Due to some incompatibility with one or more blocks created on or after 12 July 2022, v1.x versions are apparently incompatible and will fail with

EXCEPTION: 11DbException
Db::put: Cannot allocate memory

The exact cause of the problem is not known, but it's something which has been reported with other blockchains where very old versions are used.

The fix for this is to upgrade to v2.0

At the time of the failure, there were only three known peers on the whole network using v1.x, and one of those has been upgraded to v2.0 which leaves only two of them.

Further updates now complete.
