    An absolute honor to join the cracked @Etherealize_io team. This moment feels like an inflection point for Ethereum, and I’m excited to do my part to help her reach her potential.

    SNARKS FOR NON-CRYPTOGRAPHERS ZK tech is looking like the holy grail for Ethereum scalability and privacy. But how does it actually work? What kinds of things are provable? And if it’s working, what’s the barrier to full zkEVMs? I spent the past few weeks diving in… (1/n)

    One of the hardest things for new auditors is getting your head around a code base. I remember feeling like I was aimlessly jumping in circles. Based on the DMs I've been getting, seems like this is a common experience. Here's the process I now use for every audit...

    I was auditing a governance protocol with gas refunds last week, and it got me thinking... Gas refunds usually add a base gas amount to the gas used to account for tx overhead. But if I could iterate over refundable calls from one tx, I might get refunded more than I spent.

    Ethereum security is unparalleled, but there’s still more to do to become the most reliable foundation for civilizational infrastructure. Honored to be stewarding this project to help us get there.

    instead of scrambling to learn zk in 5 days for the money, please slow down and focus on whatever fascinates you. you're never gonna outnerd the people who are in it for the ideas. just be one of those people and the opportunities will appear.

    Since the @optimismFND contest rewards were announced, a bunch of people have asked me about the logistics of working with @trust__90. How did we share information? How did we support each other? I've experimented with this a lot so figured it might be useful to share publicly.

    I've been given an incredible gift. I tried my absolute hardest on Blast. Exhausted every idea I could think of. And yet… there were 2 Highs and 15 Mediums I missed. You can't buy education this good.
