Part 6/17:
Transition from Proof of Work to Proof of Stake
Pete prompts a shift to Ethereum's most ambitious upgrade: the transition to proof of stake (the "Merge"). Lane describes how Ethereum intends to:
Significantly reduce energy consumption.
Enable scalability through sharding—splitting the network into manageable parts.
Increase security through staking, where validators lock up 32 ETH (~$50k+), with penalties (slashing) for misbehavior.
