Cardano Unveils Ambitious Dijkstra Upgrade Plan With Leios and Peras
Cardano is gearing up to implement a significant upgrade in its upcoming Dijkstra era, aiming to boost network throughput and settlement speed. The two-phase rollout will introduce Ouroboros Linear Leios (CIP-164) in Phase 1, which targets Q4 2026 for code completion. This phase will increase throughput through supplementary Endorser Blocks and introduce nested transactions, guard scripts, account-address enhancements, and simpler staking-reward withdrawals.
The second phase, targeting Q2 2027, will activate Ouroboros Peras (CIP-140), adding a stake-pool voting layer to accelerate settlement finality. Both phases will undergo testnet deployment and on-chain governance approval before mainnet activation. Cardano's roadmap includes various milestones, such as a Peras-compatible node release for testnet operators and a preview hard fork with two-week SPO testing window.
ADA price remains under pressure, trading near $0.17 amid the broader crypto bear market. However, the ecosystem continues to expand with these significant upgrades, positioning Cardano for greater scalability and institutional appeal once market conditions improve. The Dijkstra era represents Cardano's most ambitious scaling effort to date.
