I’m trying to figure out why the Prohashing mining pool’s ZCash client crashed sometime in the past day. The monitoring system that automatically restarts crashed coins put out an alert that ZCash is always exiting with code 1 and printing the following to stdout:
“Error: This version has been deprecated as of block height 502708. You should upgrade to the latest version of Zcash”
When I perform a Google search for that block number, there are no references returned to what fork occurred at that height.
Is anyone aware of what needs to be changed for this latest upgrade? I can find documentation, but none of it references this specific error and there’s too much money at stake to just upgrade without knowing exactly what changed.
By the way, for those who are watching, a third of the ZCash hashrate went to other coins this morning. That’s not very far away from 50%. This is a dangerous method of forcing upgrades. It’s especially dangerous not to prevent this from occurring very early on a Sunday morning when our employees are asleep but the criminals are not.
