Bitcoin & Elixir: Living the Cutting Edge
summary
Built a native Elixir bitcoin parser alongside a bitcoind reference node; basic protocol works after one night, confirmation logic takes four months of work. Two order-book engines: a linear matcher (200 lines) handles ~300,000 orders in ~2 minutes; a parallel order-book per-price-process version (also ~200 lines) processes the same load in ~7–8 seconds but remains experimental. Also created logging and orchestration tools (xlogger, hypnotoad), use Docker/Vagrant/relx/gproc/cowboy and early Erlang SSH; theft, irreversibility and complexity drive many design choices.
