My post is a secondary research regarding potential issues with weak isolation levels. It includes a link [0] to an in-depth description of what happened to Flexcoin. Additionally, the post references another similar BTC attack [1] that exploited a "lost update" due to weak isolation levels.

The goal of the post is to highlight this problem, as cited research papers clearly demonstrate that such issues occur more frequently than commonly perceived.

Again, I'm sorry that the title might be misleading and you have expected a different content.
