Ryan Condron has been a Bitcoin miner for longer than a decade. He started out with a GPU rack, upgraded his rig to FPGAs, and then was one of the first people to run ASICs. Today, he aims to decentralize hashrate with Lumerin – a hashrate marketplace. Ryan Condron has been mining Bitcoin for longer than a decade. In the beginning, he started out with a rack of video cards. Soon, he had to upgrade his hardware to include FPGAs. In less than a year, ASICs became a reality and every serious miner had to keep up. In this episode, Ryan Condron talks about his personal experience with Bitcoin mining and also presents the research he's done on the subject of decentralizing hash rate. Since hardware distribution and ownership is difficult to change, he decided to create Lumerin: a marketplace for hash rate, where people can take control of ASIC miners by renting them. This way, they don't only collect the mining rewards (as was the case with many cloud mining services). They also make decisions on behalf of the mining hardware to suit their financial interests and/or ideological beliefs. ––––––––––––––––––––––––––––––––––––––––– Early Days of Bitcoin Mining (00:00:48) The conversation starts with the guest, Ryan Condron, discussing his early experience with Bitcoin mining in 2012 and the shift to mining altcoins.
