$ADA Dijkstra era dropping in 2 phases:
Q4 2026: Ouroboros Linear Leios goes live via hard fork
Q2 2027: Ouroboros Peras activation
Linear Leios is the real alpha here—lets block producers push Endorser Blocks on top of regular Praos blocks. These reference extra txs certified by a stake committee before hitting the ledger. Translation: more throughput without bloating block size or speeding up block times.
Phase 1 also ships Nested Transactions, PlutusV4 context changes, reference-script pricing updates, and staking reward tweaks.
Both upgrades need Preview + Pre-prod testnet runs, then on-chain governance approval before mainnet.
Timeline is code-complete estimates—doesn't factor in testing or governance lag. If you're staking $ADA or building on Cardano, this is your 18-month roadmap.
