First Bitcoin Bounty Posted (CUDA Miner)

On September 14, 2010, core developer Jeff Garzik (jgarzik) posted a thread on Bitcointalk titled "Bounty: CUDA miner for Windows," offering 10,000 BTC (worth roughly $600 at the time) to anyone who could create a functional, open-source GPU miner for NVIDIA cards. This event is historically significant for two reasons. First, it was a direct response to the centralization threat posed by 'ArtForz,' the private miner who was dominating the network hash rate. Garzik realized that the only way to protect the network's decentralization was to commoditize the mining software, making high-speed mining accessible to the public rather than a trade secret held by one person.

Second, this event established the community bounty system as a primary funding mechanism for Bitcoin development. In the absence of a central company or VC funding, early Bitcoiners pooled their own capital to incentivize development goals. This decentralized R&D model became a staple of the ecosystem. The bounty was successfully claimed just four days later by user puddinpop, who released the open-source CUDA miner. The speed of this result demonstrated the efficiency of free-market incentives in open-source development.

The bounty effectively kicked off the public GPU mining era. By paying to make the software free, Garzik ensured that 'one-CPU-one-vote' evolved into a competitive market rather than a monopoly. Jeff Garzik's 10,000 BTC bounty was a strategic maneuver to decentralize the network's hash rate, creating the precedent for community-funded development that defines the cryptocurrency ethos.
