Consulting

I provide strategic and technical consulting for Blockchain and Bitcoin projects, and Ethereum smart contract audit services.

I am known for popularizing concern about the Race-To-Empty, Recursive Call, or Solar Storm vulnerability a week before TheDAO lost $50mm to the same vector.

I am a trusted advisor for small to large corporations and individuals thinking about their blockchain, Bitcoin or smart contract strategies. Read my Bio for more details, or drop me a line - I'd love to connect.

Speaking

I would be pleased to come talk to your group, large or small, usually about Blockchains.

I'm represented by Dagmar O'Toole at CSA. Please contact her for more information.
