Ravencoin is attempting to roll back four days of blockchain transactions due to a critical software flaw exploited by attackers. Two major mining pools are rebuilding the chain from before the first invalid block on August 7, a move that could erase completed payments. Meanwhile, a proposed Bitcoin rule change, BIP-110, has caused a chain split, leaving the breakaway chain 326 blocks behind the main network. Miners lack incentive to support the split chain due to its lack of market value and high mining difficulty, projecting a difficulty adjustment six years into the future.
Ravencoin is facing the possibility of rolling back four days of its blockchain history after attackers exploited a critical software flaw. Two major mining pools are collaborating to rebuild the Ravencoin chain from a point just before the first invalid block was created on August 7. This significant undertaking could result in the erasure of completed transactions and payments made during the affected period.
In a separate development within the cryptocurrency space, a proposed Bitcoin rule change, identified as BIP-110, has led to a chain split. The breakaway chain resulting from this fork is currently stalled and significantly behind the main Bitcoin network, lagging by 326 blocks. The lack of market value and the high mining difficulty associated with this new chain are disincentivizing miners from supporting it.
Consequently, the difficulty adjustment mechanism for this split chain is projected to take approximately six years to occur. This situation highlights the challenges in maintaining consensus and security within decentralized blockchain networks when faced with software vulnerabilities or contentious protocol changes. The Ravencoin rollback, if executed, represents a drastic measure to restore chain integrity, while the Bitcoin fork illustrates the potential for protocol changes to create isolated and unsupported network segments.
