Cardano Map out Dijkstra Hard Fork Road Across Four Node Releases

Intersect don outline the clearest technical road so far toward Cardano Dijkstra hard fork. Upgrade Bulletin 32 introduce four-release node sequence, new public test network and parallel testing for Linear Leios before the changes go reach the mainnet wey dey secure ADA transactions.

Cardano Node 11.2 Go Open DijkstraNet

The sequence start with Cardano Node 11.1.1, one mainnet version wey dem expect during the week wey begin September 7. The release dey designed to remove old tracing and address known Genesis-related issues. For the time wey dem announce am, version 11.1.1 don get tag for the GitHub repository but dem never still confirm am as official release wey dem recommend make mainnet operators use.

Cardano Node 11.2 go introduce early Dijkstra feature set for developers, stake pool operators and infrastructure teams. E suppose include Plutus V4, Nested Transactions, staking reward changes wey CIP-50 define and other functionality wey dem plan for the new ledger era.

Node 11.2 no go include Linear Leios and e no go be the hard fork release candidate. Instead, e go support DijkstraNet, new public network to test Dijkstra functionality before dem combine am with Leios. Intersect never announce exact launch date.

DijkstraNet and MusashiNet Go Share the Testing Work

DijkstraNet go operate side by side with MusashiNet, as the two networks go cover different parts of the upgrade.

MusashiNet still dey dedicated to Linear Leios, Cardano new block-processing design wey aim to increase network throughput. Stake pool operators and development teams dey use the network to evaluate block production, data propagation and protocol behavior under distributed conditions.

DijkstraNet go focus on the remaining Dijkstra changes, including Plutus V4, Nested Transactions, new script types, transaction format updates and extra parameters wey cover fees and staking rewards. The parallel structure go allow ledger and smart contract features enter public testing while Leios development continue on its own.

Cardano Node 11.3 dem dey target am as the hard fork release candidate, wey go combine Linear Leios with the complete Dijkstra feature set. Node 12.0 then dey planned as the final hard fork release wey match Cardano protocol version 12. None of the two versions get published release date for now.

Dijkstra Activation Go Depend on Testing and Governance

Input Output recalibrated technical delivery plan include two potential enactment windows. The moderate-confidence window run from December 5, 2026, to January 4, 2027, while the high-confidence window run from February 24 to March 26, 2027.

Intersect never publish the method behind the estimates or identify the later period as fallback scenario. None of the ranges be confirmed date for the Dijkstra hard fork.

Phase 1 code completion still dey targeted for the fourth quarter of 2026. Mainnet activation need extra steps, including Preview and Pre-production hard forks, testing periods for stake pool operators and one on-chain governance action wey involve DReps, SPOs and the Constitutional Committee.

Linear Leios dey inside Phase 1, while Ouroboros Peras still separate inside Phase 2, with code completion target for the second quarter of 2027. The first phase go introduce the structures and parameters wey Peras need, so that dem fit activate am later without another ledger era.

The immediate milestone no be mainnet date but the release of Node 11.2. Once e dey available, DijkstraNet go give operators and developers their first public environment to test most of the new era ledger and smart contract functionality before dem combine am with Leios and prepare am for the network wey dey process ADA.
