Apirone Restored Litecoin Operations Within 24 Hours After Network Reorg

Crypto payment processor Apirone resumed Litecoin (LTC) operations within a day of the April 25 network incident. User funds remained safe, according to the press release.

The Litecoin network experienced a 13-block reorganization triggered by an attempted exploit of the MimbleWimble Extension Block (MWEB) protocol.

An attacker submitted a block with malformed MWEB data at height 3,095,931. Upgraded nodes rejected the invalid block but encountered a bug that prevented them from continuing normal mining. Meanwhile, nodes running outdated software kept extending the invalid chain.

Mining pools coordinated to overtake the bad chain and restore consensus on the valid one. The Litecoin development team released version 0.21.5.4 on the same day to fix the issue.

How Apirone responded

The Apirone team identified the problem and confirmed it was a network-wide event. The service posted updates across multiple channels explaining the issue, potential consequences, and recovery steps.

“We updated nodes to the latest Litecoin Core version, synced with the valid chain, re-verified all incoming and historical transactions, and restored correct balance displays,” the Apirone team said.

During the disruption, outgoing transactions were temporarily unavailable as the network could not process them. The network kept logging incoming operations. Full LTC processing resumed within 24 hours.

New notification system

Following the incident, Apirone announced an upgrade to its notification infrastructure. Upcoming releases will support alerts via Email, Telegram, and Discord across several event categories: payments, receipts, security, callback errors, and technical notifications.

The system is designed to keep users informed about transaction statuses, network incidents, and maintenance windows in real time.

Earlier, ForkLog reported that Apirone sponsored a yacht racing team in Spain.
