RockstarTamás Blummer is an entrepreneur and quant software developer with 13 years of experience building production-grade financial and Bitcoin systems from startup to enterprise scale. He founded Bits of Proof, which produced early modular Bitcoin infrastructure and the backend for the first hardware wallet, and later led the Budapest engineering office as Chief Ledger Architect at Digital Asset. Tamás combines deep market-risk and ledger expertise from senior roles at Deutsche Bank, Morgan Stanley and MSCI with hands-on systems engineering—designing mining control software that once powered up to 5% of the Bitcoin network. An active open-source contributor, he has made substantive backend contributions to the prominent rust-bitcoin library, including segwit integration and consensus-related features.
