Casper Network resumes operations after the recent security incident

Casper Network has resumed operations after resolving the recent security breach.
Two blocks were removed; a new Casper-node binary was deployed and scanned.
Other July breaches affected WazirX ($230M), Compound Finance ($24M), and more.

The Casper Network has resumed operations following a temporary halt due to a security breach.

On July 31, 2024, at 3:18 pm UTC, 64 validators, representing 85% of the staked CSPR, unanimously agreed to resume network validation. This decision marked the network’s recovery and return to full functionality.

Two blocks removed from Casper blockchain

The incident highlighted the critical importance of vigilance and proactive measures within the ever-evolving realm of blockchain technology.

The Casper team, in collaboration with validators, engineers, and other stakeholders, successfully resolved the breach through a coordinated and decentralized effort.

The disruption, occurring mid-era rather than at its conclusion, presented significant technical challenges.

To address the issue, the network removed two blocks containing four transactions, effectively orphaning these transactions and their impacts on the blockchain.

A new Casper-node binary and standard configuration files were deployed, and a global scan of the blockchain was conducted to detect any other potential exploits.

Validators played a crucial role in the recovery process, manually initiating the upgrade and implementing the new version of the software. This step required precise real-time synchronization.

Once at least 66.7% of the consensus stake approved the node restart, the problematic blocks were removed, and block creation resumed.
