Plomin upgrade readiness

This page outlines the engineering and ecosystem readiness for the Plomin hardfork upgrade

On January 29, 2025, Cardano achieved the transition to full community governance with the enactment of the Plomin hard fork

The upgrade was enacted on-chain after the hard fork was approved by stake pool operators (SPOs) and the interim constitutional committee. This is a truly momentous achievement, not only for Cardano but for the entire blockchain industry.

This is Cardano’s first community-enacted upgrade, with all future protocol changes now fully in the hands of the community. The decision began with CIP-1694, which was developed over two years and included community workshops. It is the only hard fork to make such an epochal change to blockchain governance

This page represents the readiness and status of the Plomin hard fork as of the January 29, 2025. Now that the Plomin hard fork is enacted this page will not be updated

Core Infrastructure Components

Core infrastructure encompasses all technologies included within the Cardano Node, as well as some key tools.

Release

10.1.4

It is required that all Cardano stake pools and relays upgrade to this node version in order to mitigate a potential DoS attack following a hard fork to Protocol Version 10 ("Plomin" hard fork on mainnet). It is recommended that all other node users upgrade to this version. Node users who do not upgrade put themselves at risk of a potential DoS attack following the hard fork. Node 10.1.4 is a mainnet-ready release of the Cardano node that is capable of crossing the Chang#2 ("Plomin") hard fork. It adds safeguards at the mempool level to block specific types of transaction that could lead to a DoS attack following the hard fork. For further details about cardano-node 10.1.4 please see the release notes for node versions 10.1.1, 10.1.2 and 10.1.3.

Note that, although staking rewards will continue to be earned as usual, in order to withdraw their rewards, following the Plomin hard fork, Ada holders will need to delegate to a DRep, which may be one of the pre-defined options, a single key or a Plutus v3 script. Until the hard fork, rewards may be withdrawn normally. Although following the hard fork, rewards may not be withdrawn unless a DRep is delegated to, rewards will continue to accrue to the Ada holder normally, regardless of whether or not a DRep is delegated to.

Readiness and Updating this Page

Readiness is a self-attestation from the community and ecosystem, facilitated at Intersect, of being technically ready for the Plomin upgrade.

Signalling readiness is important, this allows the on-chain governance, SPOs and the ICC in the case of Plomin upgrade, to make an informed decision voting for the governance action to enact the hard fork.

The community is encouraged to participate in updating and maintaining the status’ and details contained within this ecosystem readiness page.

You can do so by suggesting updates via this Intersect GitHub documentation repository, a simple how to guide provided here. Alternatively, if you find any information on this page incorrect or misleading please email: [e-mail] and request an update or correction.

Status key

Enacted: Governance action has been applied on chain

Ratified: Governance action has reached required voting thresholds, and will normally be enacted next epoch

Expired - Governance action has failed to reach the required thresholds

On-Chain - governance action has been submitted to the blockchain and is available for voting

Pending - Governance action has not yet been submitted to the blockchain

Metadata for all Intersect governance actions can be found here on the Intersect Gitbook repository.

SPOs

Stake pool operators should upgrade to a supported mainnet node 10.1.4 version in readiness for the hard fork. Below we compare the prevalence of Cardano blocks created by Node versions.

As of January 22nd, 2025: 89% of blocks created on mainnet, within the current epoch, where created using the hotfixed 10.1.4 version (which reports as 10.2) Live data can be seen via Cardano explorers such as Pooltool.io

Exchanges

Exchange readiness is tracked against the top exchanges by ADA liquidity (as reported by Cexplorer/hfs).

For the latest info on Exchanges by Liquidity please visit: Cardanoscan (source) and Cexplorer.

As of January 22nd, 2025, 84.5 % of exchange liquidity has been reported as Ready for Plomin hard fork.
