Privacy-focused Zcash blockchain has not produced a block for four hours

Summary

Zcash experienced a rare network pause on Wednesday, with block production stopping for more than four hours. The last block before the outage was number 3,364,601, created at 5:27 AM UTC on June 3. Under normal conditions, Zcash produces a new block about every 75 seconds, so the halt prevented new transactions from being confirmed and effectively froze the payment network for several hours. The cause was not publicly explained, and no official statement had been made at the time. Despite the disruption, ZEC has performed strongly, rising 8% over the past week and 46% over the past month, even as the broader crypto market weakened.
