Statement from ZcashCo on Poloniex situation (July 2017)

Of course you can. When you sync your wallet again, the deposits will show up.


For the record as the developer behind the Windows port of zcash (all of the full nodes listed as "BeanStalk" on the network map link @paige linked above), I have not had any reports of issues with the zcash network itself from any of my users.


Flypool has more than 50% hashrate network…I think Poloniex disabled their Zcash wallet for defense 51% risks...

11 posts were split to a new topic: Flypool hashrate discussion (split from Poloniex wallet situation thread)

For the record, I think that mining centralisation is a serious problem, for Zcash and for PoW blockchains in general.

Note that choosing an ASIC-friendly PoW has its own problems: if you choose SHA-256d then you're at the mercy of huge Bitcoin mining farms who are in a position to do the same kind of attack @ZC93 points out for ETH miners, and if you choose a different ASIC-friendly PoW algorithm then no-one starts out with any ASICs, which makes the security in the early stages very questionable.

In any case this thread started with the announcement concerning Poloniex, and drifted into the topic of mining centralisation because of @Kulla's speculation that the reason Polo had disabled ZEC was because they were concerned about 51% attacks. I see no evidence for that speculation -- and if Polo were actually concerned about that, wouldn't they be motivated to say that was what it was about rather than leave everyone in the dark?


Update: Some users are sharing in the community chat that Poloniex is responding to support requests about disabling ZEC:

"...we are currently experiencing a momentary problem with the wallet and had to disable it for maintenance."

Also, lets keep this thread on topic. Please start a new thread if you want to continue to discuss concerns about flypool mining percentage.


Well that is a long maintenance for sure and had detrimental effect on its price. Earlier today, litecoin wallet was disabled as well but it was fixed 30 minutes back.

Interesting. They went from "Zcash team needs to fix it" to " it's just maintenance". Where's the eyeroll emoticon???


They seem to just have a standard notice which they reuse regardless of situation.


That's a horrid "standard notice" I would say. Quite frankly, I would pose that there may not have been such a drastic drop in price had it been simply "down for maintenance". For weeks our price has been aligned with ETH and almost always higher than ETH even with drops, this time we fell well below and are struggling to close the gap with ETH again.

Just an observation of course. Personally, I would have a chat with Polo about their "standard notice" to ensure something like this doesn't happen again in the future? You know...if you can get a hold of them :wink:


It was promised to get updates on situation with Poloniex to this thread.
So i assume it is no news? Or just no positive news?

I really hope to hear something soon.

I believe it's been a week already.

I've contacted poloniex and this is their response:

We’re very sorry to inform you that we are currently experiencing a momentary problem with the wallet and had to disable it for maintenance.&n bsp;

As soon as the wallet is re enabled your deposit will credit.

Wonder if it has anything to do with Alphabay?

Still no news on this issue from Poloniex?:confused:

I really wondering why this thread is so quiet .. some people got stuck 10+ coins there or on transactions.
Dear @zcashcommunity tell when situation going to be solved and what is current status is?


polo seems to have serious problems. unsure there's anything anybody outside polo can do. zcash has always been fine during this "mishap". terrible exchange, but sure they'll eventually fix their issues.


Im waiting for one week. Poloniex and Zcash please made it quicker! Im really nervious about this problem!
