Smart contracts were the first era, and the Merge was the second.
Vitalik just published the plan for the third, and it replaces almost every major piece of the protocol.
Some things that stood out to me:
• Verification moves to recursive STARKs, enshrined directly in the protocol. Pair that with the new state design (100 TB of scalable state by 2030, and rewriting an ERC20 for it cuts fees over 10x) and gas limit increases planned "many times over the next ~5 years."
This is the L1 scaling itself instead of outsourcing everything to L2s. Makes me wonder how Layer 2s will adapt.
• Quantum safety jumped way up the priority list. My take is a quantum-safe Ethereum starts eating into Bitcoin's store of value story.
One chain will have answered crypto's biggest long-term threat while the other is still debating soft forks.
• Privacy moved from afterthought to first-class protocol goal. That's a real differentiator against Solana. And unlike Zcash, you get smart contracts and liquidity on top of it.
And that's just the protocol layer. Slot times are set to drop repeatedly over the same window, which is what makes PropAMMs on the L1 viable.
On-chain execution that can genuinely compete with CEXs.
