Rockstar🎓
Top SchoolJorge Timón is a veteran software engineer and cryptocurrency pioneer with over 13 years of experience building and shaping alternative payment systems and blockchain protocols. As co-designer and founder of Freicoin and a co-author of the pegged sidechains proposal, he blends deep protocol-level engineering (contributions to Bitcoin Core, Bitcoin XT, Peercoin, Dash, Zcash, PIVX and more) with monetary theory and complementary-currency design. He co-founded and engineered at Blockstream, serves on multiple Lifeboat Foundation advisory boards, and has practical front- and back-end experience—from Ripple’s UI to core consensus and chain-parameter work across major crypto projects. Jorge’s work uniquely couples formal software craftsmanship (test automation and refactors) with provocative economic ideas like demurrage, demonstrating both hands-on code quality impact and long-term systems thinking. Based in Spain, he frequently bridges academic monetary philosophy and production-grade open-source implementations, making him a rare mix of theorist, protocol hacker, and pragmatic maintainer.
