Building Bitcoin implementation in Gleam programming language—here's an interesting experiment. Successfully synced block headers across Bitcoin testnet 3 and testnet 4, which validates the core functionality works as intended.

The interesting part? Zero prior experience with Gleam before this project. Executed most of the development entirely on mobile using Claude Code, which meant rapid iteration and problem-solving on the fly. Incorporated end-to-end testing throughout the process to catch issues early.

The whole experience demonstrates how modern AI-assisted development tools can accelerate blockchain protocol implementation, even when working outside your usual tech stack. Sometimes the best way to learn a language is just diving in with the right tooling support.
