Last summer we announced the beta release of a clean-slate implementation of TLS in pure OCaml, alongside a series of blog posts that described the libraries and the thinking behind them. It took two hackers six months — starting on the beach — to get the stack to that point and their demo server is still going strong. Since then, the team has continued working and recently presented at the 31st Chaos Communication Congress.
The latest example goes quite a bit further than a server that just displays the handshake. This time, the team have constructed a Xen unikernel that’s holding a private key to a bitcoin address and are asking people to try and break in. Hence, they’ve called it the Bitcoin Piñata!
