Jeff Garzik has long been at the center of developing and commercializing open source software related to Bitcoin and blockchain technology. Before co-founding Bloq to develop blockchain solutions for a multi-chain world, he spent five years as a Bitcoin core developer and ten years at Red Hat. His work with the Linux kernel is now found in every Android phone and data center running Linux today. Jeff serves on the advisory boards of BitPay, BitFury, Netki and WayPaver Labs. Among the earliest contributors to Bitcoin, the 15,678 BTC Jeff gave away in developer bounties for the then-nascent project is today worth almost $1 billion.
