The CTO Podcast with Fexingo · 2026-07-18 · 10 min
In September 2022, Ethereum completed the Merge - the most consequential single upgrade in blockchain history, moving from proof of work to proof of stake. Lucas and Luna dive into the technical architecture behind the transition: how client teams coordinated the Bellatrix upgrade, the Paris execution layer trigger, and the post-Merge validator economics. They discuss why the Beacon Chain ran in parallel for 18 months, how node operators prepared, and what the shift means for Ethereum's energy consumption - dropping from 0.2 percent of global electricity to roughly 0.002 percent. Specific focus on the engineering decisions that made a seamless transition possible for 500,000 validators and millions of users. #Ethereum #ProofOfStake #TheMerge #Blockchain #Crypto #Validator #BeaconChain #Consensus #Engineering #Architecture #Business #Technology #Web3 #Infrastructure #Scaling #FexingoBusiness #BusinessPodcast #CTOPodcast Keep every episode free: buymeacoffee.com/fexingo
