Rockstar

Timo P is a Bitcoin-focused engineer and researcher with nine years of experience building observability and monitoring tools for the Bitcoin network, especially around mempool, mining pool transaction selection, and P2P anomalies. He has contributed tracepoints and USDT support to Bitcoin Core and added testing and tracing to multiple implementations, work that directly supports real-time network and attack monitoring solutions like CoinMetrics’ FARUM. After Chaincode Labs residency he worked freelance for ShiftCrypto and CoinMetrics, accepted a Coinbase grant to focus on open source, and later received support from Brink and other grants to continue improving Bitcoin Core’s tracing and Signet tooling. He mentors and publishes for the developer community (bitcoin-dev.blog) and has practical experience instrumenting hundreds of Stratum servers to detect network splits early. Not obvious from titles: he blends low-level patching of Bitcoin Core with data engineering and tooling that turns protocol observations into actionable monitoring and testing infrastructure.
