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.

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.

29 October 2022: v2.1.2 now available - this fixes the previous AuxPow fail in v2.1.1

NEW EXCHANGE

Nyancoin now listed at https://txbit.io/Trade/NYAN/USDT

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.

Nyancoin can now be traded on https://atomicdex.io/ , a combined wallet and decentralised exchange.

All the usual warnings about using such things still apply.

https://nyanexchange.com/
is currently OPEN for withdrawals only.
Please withdraw ALL balances as soon as possible.

Trading and deposits are disabled, and will not be available again.

New Nyan exchange: https://nyanexchange.com/

This is currently being developed, but is functional.
The usual cautions about not leaving large amounts on this or any other exchange apply.

Nyan is still listed there against BTC and DOGE.

Note that most of the exchange is only visible when logged in.

Tradesatoshi have announced today (7 July) that they are delisting Nyan on 15 July 2019 - only one week from now.
https://tradesatoshi.com/News/379/NYAN-Delisting

Please go there NOW and cancel any orders, then withdraw all Nyan to another exchange, paper wallet or the software wallet.

In case you didn't read that - you have 7 DAYS in which to withdraw all Nyan from that exchange.  Don't delay, withdraw today.

FINAL REMINDER - Nyancoin (and at least 50 others) being delisted from Cryptopia on 10 January 2019.

You have about 24 hours to withdraw any Nyan balance from there - or lose it for ever.  

Check the other 50+ coins being delisted as well - the same applies to those.

Updated ANN with newest releases that remove the alert system.

There were previous threads that were not in anyone's control anymore, that were still advertising Cryptsy as an exchange, so we started a new thread.

Thanks to Woshib.

Also, if no one wants to pick up the dice/faucet site, maybe we can just crowdfund some btc to keep it up? I could throw in 0.025 or so.

Windows wallet download links updated. 

Also, it looks like faucet and dice site may go away unless someone wants to take them over:
