The rollback decision by Flow has caused quite a stir. It is understood that Alex Smirnov, co-founder of the cross-chain bridge deBridge, publicly criticized Flow for deciding to roll back the blockchain without sufficient communication and coordination with key ecosystem participants such as bridges and exchanges. This move could pose greater systemic risks than the original security vulnerability.

As one of the main cross-chain bridging partners of Flow, deBridge was not notified in advance at all. This is awkward — a rollback could lead to a series of problems: assets of cross-chain users may be duplicated, and deposits cannot be properly reconciled. Smirnov bluntly stated that such a situation would result in a poor experience for cross-chain users.

His suggestion is that Flow’s validator nodes should suspend validation work until a clear remediation plan is established and sufficient coordination with all ecosystem parties has been completed. He also questioned whether Flow’s rollback decision process is transparent enough, and emphasized that accountability needs to be clarified. This highlights the importance of ecosystem coordination — unilateral decisions can easily backfire.
