The Solana network did not produce on June 1 new blocks for more than four hours due to a failure in the processing of “long-term non-targeted transactions,” which led to a consensus violation.
The developers disabled this type of operation and asked the validators to restart the blockchain.
Durable transaction nonces are mostly popular among crypto exchanges. The function is intended for token holders who use complex automatic signing settings, which is why they cannot always promptly prepare transactions for registration on the blockchain.
For example, a custodian who signs a transaction from two isolated devices may not have time to complete the work within one block. A normal transaction on the Solana network will not work in this case, however, the above function allows you to bypass this limitation and pre-sign offline.
One of the Solana validators, Stakewiz, has noted the problem with this type of transaction has long been known. According to him, on May 28, a similar error was already observed, but it did not affect the cluster.
