[ANN] Firo (FIRO) - Implementing ZKP privacy without trusted setup

[zcoinofficial]

We're doing one last final round of tests. If all goes well, we'll release this version soon. Fingers crossed.

We're stress testing our Testnet with the latest code and it seems to be all good at the moment but we're trying a few other scenarios.

Code we are testing is here:
https://github.com/zcoinofficial/zcoin/tree/core_upgrade

Once it is ready it will be merged to master and new binaries released. Thank you!

What's this upgrade and binary about?

[zcoinofficial]

Hi all, the new release is out!
Binaries will be incoming in a few hours now but we wanted to get these out to the pools/exchanges that need to upgrade.

https://github.com/zcoinofficial/zcoin/releases

This should fix the transaction stuck issues that arose from some incompatibilities with the Bitcoin 0.13 code resulting in pools not processing the transaction in the mempool.

upgrade done.

cheers

Still no connections for Cryptopia's wallet ...
Already 2 days when it took only few hours for Bittrex.

[zcoinofficial]

We are happy to announce our latest Zcoin release which resolves transactions that were not being processed by mining pools.

All major pools, MiningPoolHub, Suprnova and Zpool have updated their Zcoin nodes to the latest release.

The network has now processed all transaction backlog and is operating smoothly.

Thank you to everyone who helped provide logs and tests and the pools that updated at record speed.

Instructions

Make sure back up wallet.dat before updating to this version.
You can do this from the GUI by going to File>Backup Wallet.

If you are from version 0.8.7.9 and earlier, you will need to do a reindex.
Read this guide on how to reindex.

If you are compiling from source, note updated build instructions from readme.md. If you're from 0.8.7.9 earlier, please do a fresh git clone into a new directory.

Changelog

Resolved problem with pools not accepting certain transactions from mempool

Acknowledgements

Thanks to MiningPoolHub and Flap Pool in providing their debug logs which helped us greatly when troubleshooting.

Great job team! Everything back to normal now. Just be sure to be prepared for this next time you launch a new update. Maybe contact and help mining pools update before anyone else so it doesn't happen again

Also, Znodes coding has started!

Thanks. Definitely learnt from this but glad everything is back in smooth running order and even better with the new core!

[zcoinofficial]

With the Zcoin core upgrade completed, we have begun work on Znodes and our user interface. Zerocoin improvements are underway as well. $XZC Will keep you posted thanks!

Team will be having a good night's sleep.

We recommend miners to switch some hashrate to both Zpool and Suprnova. Especially Zpool since their hashrate is much lower!

Hi,

regarding new nvidia ccminer by djm.

If I already compiled source against cuda8 and compute_52 ONLY (GTX9XX series) - do I gain some hashrate on top?
(since github says (more or less) gain came from compiling against compute_52 for cuda8)

Any parts rewritten or only compilation optimization?

Thx

[ironmaik]

tested - for me its the same result as I already built against cuda8

[asmodyus]

So no blocks found today on supernova yet is this normal?

[Rabinovitch]

If you really care about the healthy network and 51%-attack, why don't Zcoin developers adapt p2pool for Zcoin and post links to it's source code and compiled binaries in the OP?

Yup devwarrior one of the community members is giving it a go but if anyone wants to chip in and help out, let us know, there will be bounties available for this

Just compilation. Also he has a CUDA9 version.
