People often ask me "How did you learn how to hack?" The answer: by reading. This page is a collection of the blog posts and other articles that I have accumulated over the years of my journey. Enjoy!

Sony (not that Sony) has an L2 blockchain built on the Optimism Stack. They attempted to block unapproved tokens at the sequencer level. Their policy? If they don't like your contract, you get a "forbidden" response. No questions asked. This is a direct violation in the purpose of blockchain!

Early traders on the blockchain got rekt when Sony blocked transactions. If you can't execute a transaction when trading, then you're going to lose money. Damn, this is bad...

The Optimism Stack was built with this issue in mind: the sequencer can be bypassed. A transaction can be forced to the L2 by sending it through the L1, skipping the sequencer altogether. You can censor at the RPC level but you cannot sensor at this level.

Blockchains are meant to be open and let others execute things. In the real world, there are rules and regulations on what is allowed though. So, a company trying to write their own rules is going to happen. Good post!
