👋 Hi I'm Calvin 👋

I am an open source developer based in Seoul that works on scaling Bitcoin.

Nowadays I'm usually:

  • Working on utreexod, a Bitcoin full node with Utreexo accumulators
  • Working on utreexo, a dynamic hash-based accumulator for Bitcoin
  • Working on btcd, a bitcoin implementation in Go
  • Being a water deer

If you'd like to talk/grab a coffee with me or send me pictures of cute water deers, I'm reachable at calvin@calvinkim.info!
