According to Foresight News, Pavel Shabarkin has revealed a security vulnerability in Scroll that could lead to indefinite reorganization of the Scroll L2, potentially halting the chain's operations and affecting over $100 million in Total Value Locked (TVL). Shabarkin initially reported this critical issue on February 17, but claims that Scroll downplayed its severity and categorized it as a known issue.

Shabarkin requested an investigation and intervention from Immunefi, a platform for bug bounties and security services, but alleges that Scroll's response was inadequate. As a result, Shabarkin publicly disclosed the issue to highlight Scroll's poor handling of security, unfair resolution processes, and unsatisfactory attitude towards white-hat hackers.

LinkedIn information indicates that Pavel Shabarkin is currently a Senior Blockchain Security Engineer at Quantstamp, a blockchain security company.
