Cardano Dijkstra Go Split Linear Leios and Peras Into Two Phases
Dijkstra Phase 1 go introduce Linear Leios and new Cardano ledger era, while Ouroboros Peras dey prepare for separate Phase 2 activation. Dis structure give di two protocol upgrades dia own testing and governance paths.
By SongMarketCap
Cardano’s Dijkstra upgrade no go activate all di planned consensus change at once. Phase 1 go introduce new ledger era,
Protocol Version 12, wit Linear Leios and wider set of ledger changes, while Peras dey planned for later activation inside di same era.
Intersect dey currently target Phase 1 code completion for Q4 2026, with Peras targeted for Q2 2027. Dose dates na development estimates, no be confirmed mainnet hard-fork dates.
Linear Leios Go Enter Dijkstra First
Linear Leios na di main scaling component for Phase 1 and e represent simplified implementation of di broader Ouroboros Leios design.
Existing Praos blocks go extend into Ranking Blocks, while Endorser Blocks go provide extra capacity for transaction processing. One stake-based committee dey certify Endorser Block before dem include im certificate for later Ranking Block and apply di associated transactions to di ledger.
Di Linear design remove Input Blocks and di broader model of concurrent Endorser Block production wey full Leios designs get.
Intersect select dis approach to move part of di Leios architecture toward production without introducing di extra transaction-structure complexity wey di broader design require. Dem documentation still note say some alternative approaches bin create dApp user-experience concerns wey dem consider no suitable for first deployment.
Dijkstra Phase 1 include additional ledger changes like Nested Transactions, Guard Scripts, Plutus V4 Script Context and new block-body serialization structure. Together, dem form di wider transition to di new ledger era.
Dem never define single TPS figure as Dijkstra mainnet target. Linear Leios fit operate under different configurations depending on transaction size and protocol parameters, with capacity expected to increase small small after activation instead of launch immediately for theoretical maximum.
Peras Dey Prepared Without Another Ledger Era
Peras no go activate for Phase 1, but part of di infrastructure wey e need go don already enter.
Dijkstra include di codec extensions and protocol parameters from CIP-140 wey dem need for later Peras activation through protocol version change inside di existing era. So structural changes fit complete during Phase 1 without forcing Cardano to do another full ledger transition when Peras ready.
Di protocols still address different areas of network performance. Linear Leios dey expand transaction-processing capacity, while Peras add one voting layer on top of Ouroboros Praos wey dem design to speed settlement and increase confidence for di canonical chain earlier.
So Phase 2 na separate consensus upgrade, no be unfinished part of di Leios deployment. E fit pass im own testing and ratification process after di required ledger foundations don already dey in place.
Code Completion No Mean Dijkstra Mainnet
Di current Q4 2026 target na for Phase 1 code completion, no be guaranteed mainnet activation date.
After Dijkstra-compatible node release, di upgrade must pass through Preview and Preprod hard forks, stake pool operator testing and network-readiness checks. Mainnet Hard Fork Initiation governance action fit follow only after dem complete dose stages.
Linear Leios still dey tested through di Musashi Dojo environment, where dem don demonstrate node synchronization, Endorser Block certification and transaction flow. Dem dey use dat work to refine di parameters wey go later determine production behavior.
Dijkstra still require targeted amendment to di Cardano Constitution. New protocol parameters need corresponding constitutional guardrails so governance fit modify dem within defined ranges after activation.
Di proposed amendment na technical for scope and e no change existing governance roles or voting thresholds. Di current target na to submit di combined amendment by epoch 655, beginning September 11, 2026, followed by DRep ratification and constitutionality review by di Constitutional Committee.
Dat sequence leave deliberate gap between engineering completion and network activation. Dijkstra fit establish di ledger changes wey Linear Leios need first, while di groundwork wey dem don already embed for Phase 1 go allow Peras to follow later as separate protocol decision, no be another full ledger-era transition.
