I believe the same. I mined SIGT before and ROI'de some good amount with spike but then it kinda died. I still have some SIGT mined from that time.

XZC is solid.

Awesome news for the listing on Binance.

Same here. Devs posted they are aware and working on fix.

Why this algorithm loads 1060 and 1070 much worse than 1080 and 1080ti?

Cryptopia closed both Zcoin and Smart cash wallets due to a Zerocion exploit.

Cryptopia closed both Zcoin and Smart cash wallets due to a Zerocion exploit.

Is there a bug in Zerocoin ?

[Mike011]

"A Zerocoin related supply bug issue was discovered earlier this year by the Zcoin project https://zcoin.io/important-announcement-zerocoin-implementation-bug/11 It seems, however, not all security holes were plugged since this incident took place. The Zerocoin code seems to have other vulnerabilities which could be exploited by potential attackers. After doing some research, we have discovered that Zcoin, another project using Zerocoin tech suffered a similar exploit, even though they are yet to issue a statement. Over 14k Zcoins that shouldn’t exist have been created using this exploit between November 1st and November 4th. The attack on the SmartCash network took place after Zcoin got attacked and after their devs released a quick Sunday patch to stop the bleeding. The attack could have been prevented had they told us about it. Hopefully, we will all learn to work together in the future. We can’t say for sure if other Zerocoin based coins like PIVX also got attacked, but looking at the recent Zerocoin PIVX action, that may have been the case: During this 15 hours period, between Block 892275 2017-11-06 17:41:03 CET and Block 893145 2017-11-07 08:19:16 CET more than 260K PIVX were reclaimed/spent than minted/renewed."

Zpool.ca also removed lyra2z algo and Zcoin currency since yesterday I checked. Back to MPH for now.

PIVX was also affected.

https://forum.pivx.org/t/update-on-recent-zerocoin-protocol-exploit/2753

"The exploiter was able to create multiple proofs for a single mint and create multiple serials, which he/she then converted to PIV. The exploit that has occurred was located in the base code of the libzerocoin library."

Zpool will reopen once we release the wallet sync fix. We are just testing our latest build to make sure it holds. Thus far, we have ran more than 12 hours without error but are monitoring it. I don't want to bother ocminer and mph until we have tested this further as they have a lot of other coins to manage. For those of you who urgently want to move your coins, you can drop me a note on Telegram and I can extend test binaries for you to sync up.

As for the Zerocoin issues, we already issued a statement.

http://zcoin.io/zcoin-hard-fork-statement/

We already patched the libzerocoin library and indeed the first coin with Zerocoin to do so, and it's already working on live so that vulnerability is closed and hence why Coinomi kept our wallets up and running.

Prior to releasing the update, we did make contact with PIVX's lead dev presstab to tell them to look into our libzerocoin fixes and they are now patching their libzerocoin as well (or may have done so already). We are exploring other opportunities to collaborate with PIVX to make Zerocoin better for everyone. It was also nice to speak to s3v3nhacks more who also made contact.

For SmartCash, their code is primarily a fork of our old 0.8 core code and we have reached out to leoreinaux (their dev) with an offer to investigate into issues but we aren't able to spare our resources to rewrite the code for the old core as we are working on our own fixes and Znode development. Our Zerocoin code has changed since the 0.8 fork and currently, it is unclear how the exploit occurred for Smartcash and will take time to look into. We understand Smartcash are already working to move to the new 0.13 core base as well.

Since Smartcash have disabled their Zerocoin functionality it isn't very urgent. We will look into it as soon as we are able and we hope that their team can also work on this. Leoreinaux has provided us some info on the problematic transactions in Smartcash so which we will look into to assist to investigate the cause when we can to see if we can all learn from it.

Hey guys,
don't forget that you can check your current profitability for ZCoin and compare it to over 20 other coins at:
