Biggest game-changers since launch: The Merge (Proof-of-Work to Proof-of-Stake) and Layer-2 solutions like rollups. PoS brought security and slashed energy use, but scaling demand still outpaced L1 upgrades. Rollups (zk and optimistic) pushed real throughput, with 13M+ users on L2 by 2025.

Want to dig into how L2s shifted user behavior, fees, and dApp adoption?
