#zcash批准150万美元漏洞赏金
Just swapping out a backend system. It sounds like the kind of update that’s almost not worth mentioning.. But all that switching has to do with the blockchain that the funds have been working on recently, and that’s exactly one of the main lines..

A U.S.-licensed exchange replaced its own software for running Zcash, switching from Zebra to Zakura. After the switch, that machine managed to catch up with the latest progress of the entire chain again. The time dropped from nearly a full day to a little over six hours. The developer also ran a separate test: Zakura took four hours and twenty minutes, while Zebra would take nearly twenty-one hours.
On the surface, it looks like it’s just an operations-efficiency issue.. But the timing is very sensitive, because Zcash’s NU7 upgrade is preparing to squeeze block time from 75 seconds down to 25 seconds—meaning the batch density the machine has to handle triples. The testnet is scheduled for October 6, while the mainnet is currently set for November 5.
Why does the exchange make this change before the upgrade? The logic is actually straightforward.. When users deposit ZEC, whether it can immediately turn into available balance depends on whether the exchange’s machine keeping pace with the chain is up to date. If the machine falls behind, once the coins arrive but the balance hasn’t updated, the exchange usually can only temporarily pause deposits and withdrawals of that coin. How long that pause lasts depends entirely on how long it takes a backup machine to rebuild the chain’s records.
What’s truly worth paying attention to isn’t just this.. It’s that this exchange’s two founders have their reach far beyond the exchange itself. Their investment company led a $59 million investment into a listed company that holds and mines Zcash. And in August, they sold their own Zcash mining rig fleet to the same company for $33 million. And the ZEC that company holds—its trading and custody are still handled by this exchange. Mining rigs, holdings, exchange, and backend software: it all loops around into a closed circuit.
This timing also points to another fact.. While BTC has been grinding back and forth between 82,000 and 83,000, funds have nowhere else to go, so they start clustering on a main track that has already started running. Privacy is one of those tracks, and among them, Zcash is the most representative target.
But there’s one thing that nobody has answered.. This exchange hasn’t disclosed how well the new software actually performs under the new block-production rhythm of 25 seconds. And if/when the upgrade really goes live, the thing that fails to keep up is never the chain—it’s the interfaces that haven’t been prepared.
What’s really worth watching next is the results from that batch on the testnet on October 6.. It will determine whether the date of November 5 truly holds.
