Cords & Gumballs

on YouTube ↗43m

" summary

A blockchain platform called Corda is built from 117,700 lines of Kotlin by about 28 full‑time developers with ~10,000 repo commits and ~500 trained bank engineers; it runs business processes as serialized, checkpointed coroutines, uses Intel SGX enclaves for confidential execution, and a modified JVM to enforce determinism. A side project, Gumball, produces standalone AOT JVM binaries (demoing a 5.4 MB native binary using Avian), trades Go‑level smallness for full Java library compatibility and has Mac‑first tooling with ProGuard minification bottlenecks.
