Flow: Abandon rollback and adopt a new isolation recovery solution.

Flow officially updated its update on the attack on the X platform, stating that it is abandoning network rollback and shifting to an "isolation recovery plan." Key points of the new plan include: 1. No rollback/reorganization, preserving all legitimate user activity; 2. No need for partner replay transactions; 3. Over 99.9% of accounts are unaffected, and normal operation resumes immediately after restart; 4. During restart, accounts receiving illegally minted tokens will be temporarily restricted. Furthermore, the network will be restored in phases: Phase 1, Cadence environment goes live, EVM is temporarily restricted; Phase 2, Cadence is repaired (approximately 24-48 hours); Phase 3, EVM is repaired and restarted; Phase 4, cross-chain bridges/exchanges resume operation. The specific recovery time will be determined by the operators after confirming stability based on the actual situation.
