Which chain scrapped rollback after exploit?

TLDR

Flow (FLOW) is the chain that scrapped a proposed blockchain rollback after a $3.9 million exploit, opting for a targeted recovery plan instead per a media report.

1. The rollback idea was dropped after ecosystem backlash over decentralization risks, as noted in a report.
2. The updated plan preserves legitimate history and focuses on restricting and destroying fraudulent assets per the update.
3. Flow said there will be no chain reorganization and legitimate transactions remain valid, confirmed in the plan.

Deep Dive

1. Why It Reversed

Flow abandoned the rollback after strong pushback from partners who warned rewriting history would undermine decentralization and create operational risks. Multiple media sources highlighted the community backlash, including bridge providers like deBridge, leading to the decision reversal in late December per a report.

• Critics called rollback a rushed decision with potential harm to honest users and infrastructure, documented in a coverage.
• The Foundation acknowledged concerns and pivoted away from chain reorganization, as noted in a report.

2. Revised Recovery Plan

Flow chose to restart from the last sealed block before the halt, preserve legitimate transaction history, and target fraudulently minted tokens via restrictions and destruction per the update.

1. No rollback and no chain reorg; legitimate transactions remain valid per the plan.
2. Recovery is phased, with read?only operations and targeted account restrictions before full restoration, described in the coverage.
3. Partners and validators are involved to minimize unintended balance issues and bridge complications per the report.

3. Implications

Rolling back confirmed transactions is rare and controversial because it introduces uncertainty and undermines decentralization. Flows choice to preserve history while surgically addressing fraud reflects the trade?off between crisis intervention and immutable records, as discussed in a report.

• Partners warned rollback could create unbacked assets and complex reconciliation across bridges and exchanges per a coverage.
• The updated plan aims to protect honest users and infrastructure, prioritizing chain integrity per the update.

Conclusion

Flow (FLOW) initially considered a chain rollback after its exploit but reversed course, choosing a targeted recovery that preserves legitimate history. The decision balances security response with decentralization norms and should reduce downstream reconciliation risks for bridges and exchanges.
