Ethereum's co-founder Vitalik Buterin proposes a radical simplification of Proof-of-Stake (PoS) mechanics, suggesting capping signatures at 8,192 per slot post-SSF. As a London-based fintech analyst with half a decade in crypto, I unpack the technical trade-offs—decentralization sacrifices vs. quantum resistance gains—and why this might be Ethereum's 'less is more' moment. Spoiler: it involves fewer magic cryptographic bullets and more cold, hard node economics.
