The Flow Foundation has scrapped its controversial plan to roll back the Flow blockchain following a $3.9 million exploit. The initial proposal to revert the network to a pre-attack state sparked intense backlash from ecosystem partners, most notably deBridge founder Alex Smirnov, who <a style="color: #0000ff;" href="https://x.com/alexsmirnov/status/2005220790703136833?s=46" rel="noopener noreferrer nofollow">warned</a> that a rollback would cause more financial damage than the hack itself. Instead, the Foundation has moved forward with a “revised remediation plan” that avoids a network rollback, preserving legitimate user activity while isolating the stolen funds.

The drama began after an attacker exploited a flaw in Flow’s execution layer to unauthorizedly mint tokens and siphon funds through various cross-chain bridges. In response, Flow developers initially suggested a global rollback to a checkpoint before the exploit.
Alex Smirnov, co-founder of deBridge, one of Flow’s primary bridge providers, slammed the proposal as a “rushed decision” that blindsided partners. Smirnov argued that a rollback would introduce systemic risks, potentially doubling balances for some users while leaving others with unrecoverable assets. He urged validators to halt operations until a coordinated plan was established.

Following the industry outcry, the Flow Foundation shifted its strategy. On December 29, the Foundation announced it would focus on destroying the fraudulently minted tokens rather than erasing hours of transaction history.

Dapper Labs, the original creator of Flow, publicly supported this revised approach, confirming that “no Dapper Labs user balances or assets are impacted,” including its own treasury. Gabriel Shapiro, General Counsel at Delphi Labs, had also criticized the earlier plan, suggesting it undermined the fundamental blockchain principle of transaction finality.

The security breach and the ensuing governance controversy have taken a heavy toll on the FLOW token. Data shows the asset plummeted approximately 42% since the attack, as investors weighed the risks of network centralization.
While the network is transitioning out of “read-only” mode, the incident has highlighted ongoing struggles for the ecosystem. Once a high-profile Layer 1 competitor, Flow’s total value locked (TVL) currently sits at a modest $85.5 million, with its market cap falling outside the top 300 tokens.

Using the specialized SCONE-bench benchmark, researchers demonstrated that advanced language models can efficiently identify both historical flaws and new zero-day vulnerabilities at low operational cost. This alarming development suggests the window for relying on manual security checks is rapidly closing, necessitating the urgent adoption of AI-powered defences to counter these evolving digital threats.
