Battle of the blockchains
summary
Claims proof of stake can match proof of work security using VRFs after five years of research and a published gkl model (800 citations); proof‑of‑stake yields endogenous control versus miner mercenaries. Shelley incentivized testnet runs ~900 stake pools with ~40% participation and pays block rewards to beta testers. Base ledger performance hits ~60–70 TPS unoptimized (about 5 Ethereum), single‑shard realistic peak ~150–250 TPS, and Layer‑2 Hydra aims for thousands but changes the security model. Plutus/Marlowe separate on‑chain versus off‑chain logic so ~95% of app code stays traditional, ~5% is blockchain DSL.
