Hi, I’m Casey. Lately I’m getting into biology, learning about foundational models (e.g. Evo and ESM3) and also wet lab basics. I hope to have more to share around bio soon.

I used to be focused on crypto/ethereum. From 2015-2020, I was doing Ethereum core development. Some highlights I have fond memories of:

• Working with the EthereumJS/Ewasm team. Learned a lot about the EVM, wasm engines, and the runtimes of various crypto functions.

• Discovering a consensus bug in the BN pairing precompile, and working with the security team on fuzz testing.

• Talking a lot about the roadmap, including stateless clients, eth1x, and eth2 phase one.

• Attending several IC3 events, including the 2016 event where I participated in prototyping a zksnark feature.

• Working very briefly at String Technology, which became Dfinity.

• Being early to write about AMMs (Automated Market Makers). AMMs became popular later in the form of Uniswap and CFMMs in DeFi.
