Cardano Tags Node 11.2.0, Setting Up the Dijkstra Testnet Hard Fork to Version 12

Cardano (ADA) node 11.2.0 was tagged on GitHub on October 27, 2026, with the 11.2 release preparation merged. Stake pool operators will run it before a hard-fork initiation action moves the public Dijkstra testnet to protocol version 12, according to the cardano-node repository.

What the Cardano Node 11.2 Release Covers

Node 11.2 carries the full Dijkstra hard fork feature set apart from Leios, the scaling upgrade, Intersect said in Upgrade Bulletin #39 on October 22. The release is also expected to clear the new ledger state model (LSM) for mainnet use, with memory requirements estimated at about 12 GB when running with LSM. The Dijkstra testnet still runs node 11.1.3 and Conway protocol version 11. Operators join it with public configuration files and a testnet faucet, and testnet epochs last one day.

How the Dijkstra Testnet Hard Fork Will Work

Intersect set out two steps for the version change. The node 11.2 prerelease comes first, then a hard-fork initiation action moves the testnet from protocol version 11 to protocol version 12, the Dijkstra era. The bulletin lists no date for the version change and no mainnet activation date. The Kleioscan explorer tracks the test network.

Leios Stays on MusashiNet

Node 11.2 does not include Leios. Downstream teams test a Leios-inclusive prototype on MusashiNet, where the weekly RC 2026w42 build gives tooling teams early access before the formal node 11.3 release. That release was still at least two weeks away as of October 22. Input Output's rollout plan sets initial Leios capacity targets at three to five times current transaction capacity, rising later to 10 to 15 times. Pools must register BLS voting keys covering roughly 90% to 95% of stake before Leios can start running.

What Happens Next on the Cardano Testnet

Stake pool operators in the Cardano ecosystem are the first to run the new node on DijkstraNet. The next concrete steps are the node 11.2 prerelease binaries, the hard-fork initiation action and the first protocol version 12 blocks on the test network. Traders can follow ADA through the upgrade on the Cardano price chart. Cardano remains one of the established layer 1 blockchains.
