- On June 3, 2026, the Zcash blockchain ceased producing new blocks for a span exceeding four hours, disrupting the confirmation of all transactions.
- The last block generated was number 3,364,601 at 5:27 a.m. UTC, marking an atypical outage for a network that usually generates a block approximately every 75 seconds.
The Zcash network, known for its focus on privacy, experienced a significant interruption on June 3, as it did not create any new blocks for over four hours, raising concerns among users.
In blockchain terminology, each block represents a new entry in a continuously updating ledger. When block production halts, the system cannot confirm any new transactions, effectively freezing the transaction processing for hours.
Data from Zcash block explorers indicates that the last block was created at 5:27 AM UTC, with no further blocks produced until after four hours had passed. Typically, Zcash generates a new block roughly every 75 seconds (just over a minute).
(ZCash Block Explorer)Interestingly, despite this technical setback, Zcash's native cryptocurrency, ZEC, has seen an 8% increase over the past week, according to CoinDesk data, which contrasts with the general trend of market decline. Over the past month, ZEC has climbed by 46%.
This incident serves as a reminder to cryptocurrency investors that even established digital currencies can encounter technical difficulties. As of now, Zcash has not publicly addressed the situation.
