Stuff I like

Bitcoin. A decentralized monetary system anchored in cryptography.

  • Applied cryptography. Privacy and scalability research
  • Open source software engineering
  • Protocol design

Some stuff I do

I develop and distribute improvements to Bitcoin. My work centers on Bitcoin privacy, including protocol upgrades to Payjoin (BIP-77/78) through contributions to the Payjoin Dev Kit. I am currently focused on multi-party Payjoins, which allows for more private payments and enables counter-party privacy. To rigorously model and evaluate the privacy of these protocols we are currently developing an analysis framework.

I retain an interest in Bitcoin scalability and future softfork proposals. In the past I have work on BIP-347 and tricks that you can do with OP_CAT.

I was the CTO and co-founder of Botanix Labs where we developed side systems for Bitcoin.

My other interest is in how we can scale self-custody and make it a practical experience. I worked on Casa's multisig coordinator as well as a self-custodial lightning wallet.

I am co-host of Boston Bitdevs. If you are in the Boston area and interested in learning more about Bitcoin, please join us!
