Block product on Blockstream'southward Liquid network has resumed after technical bug related to a functionary upgrade caused many transactions to queue for hours.

In a Mon update from a Liquid oversight board fellow member identified merely as Wiz, Liquid'southward failsafe mode was activated yesterday as "an unexpected event occurred causing block signer nodes declining to validate certain parameters against each other." Equally a result, the network stopped producing blocks and transactions steadily queued in the Liquid mempool for roughly 22 hours, starting at approximately 5:19 pm Eastern Time on Mon.
