In its latest improvement proposal summary on November 1, Cardano outlined new proposals for regulated stablecoins and quantum-resistant signatures, alongside ongoing discussions on governance metadata and two completed documentation efforts.
- The Cardano CIP summary for November 1 covers proposals related to regulated stablecoins and post-quantum signature verification.
- A stablecoin draft aims to establish universal compliance requirements to enable wallet providers to support multiple programmable tokens.
- CIP-0206 introduces two quantum-resistant signature verification functions for Plutus smart contracts.
- Developers are reviewing governance metadata rules, with a focus on support for different signing methods.
- The documentation milestones for CIP-0204 and CPS-0037 have been completed, but this does not mean that all proposed features have been fully implemented.
According to the Cardano Improvement Proposals repository, the latest work involves how regulated digital assets interact with wallets, how smart contracts verify signatures, and how ADA holders can express their opinions on governance decisions.
This weekly summary, compiled by CIP editor Robert Phair, lists two new submissions, one governance issue under review, and two items completed in the most recent review cycle.
Cardano's stablecoin proposal seeks to unify compliance standards
One submission focuses on standardizing regulated stablecoins created using the Cardano CIP-0113 programmable token framework.
The draft problem statement, submitted in Pull Request #1266, argues that currently, individual programmable stablecoins often require separate integrations because their transaction requirements may differ.
For wallet developers, exchanges, and other infrastructure providers, supporting each token individually means additional technical work. The proposal authors suggest that issuers across different jurisdictions could adopt a shared set of requirements.
Unified integration will enable service providers to support multiple eligible tokens without rebuilding their systems for each issuer.
However, the proposal is still under discussion. The author has requested feedback from issuers regarding regulatory requirements and has asked infrastructure providers to assess the practical feasibility of the shared standard.
This work builds on the CIP-0113 programmable token framework, whose mainnet implementation was announced in October.
According to previous reports from crypto.news, CIP-0113 allows asset issuers to apply selected identity verification, transfer restrictions, and management controls to tokens issued under this framework.
These permissions apply to programmable assets participating in this framework, not to regular ADA holdings.
The Cardano Foundation subsequently joined a Swiss tokenization association, following the Capital Markets and Technology Association's recognition of an implementation of CIP-0113 for tokenized equity securities.
Quantum-resistant signature proposal enters CIP review
Another proposal submitted by Quantova Inc. concerns Cardano’s preparation for post-quantum cryptography.
The proposed CIP-0206 introduces two signature verification functions to Plutus, Cardano’s smart contract platform.
The author selected the ML-DSA and SLH-DSA algorithms, which have been standardized by the National Institute of Standards and Technology under FIPS 204 and FIPS 205.
ML-DSA uses lattice-based cryptography, while SLH-DSA relies on hash-based techniques. This submission proposes support for both to enable developers to verify signatures generated using different cryptographic methods.
Quantova provides reference code, coding guidelines, and test cases. The accompanying documentation describes tests involving valid signatures, tampered messages, and mismatched signing methods.
Although these tests provide a starting point, integrating the verification function into the Plutus executor, which is critical to Cardano's consensus, requires a network hard fork.
Therefore, this proposal does not represent an enabled security upgrade, nor does it imply any change to existing wallet signing methods.
Cardano's founder, Charles Hoskinson, previously discussed the risks of quantum computing and the challenges blockchain networks face in replacing existing cryptographic methods.
The latest submission addresses verification within the smart contract, while the broader migration of Cardano accounts and transaction signatures is part of a separate initiative.
Governance metadata rules are still under review.
Another topic of discussion involved how Cardano governance records identify signatures used to verify submitted metadata.
In GitHub issue 1302, the contributor questioned why the CIP-0169 governance metadata architecture no longer lists CIP-0008 as an accepted witness algorithm.
This change has raised concerns about compatibility with existing hardware wallet signing methods.
The reviewer assessed whether the previous entry should be restored and how the governance metadata specifications describe supported signature arrangements.
Subsequently, the discussion also addressed the relationship between CIP-0100 and CIP-0108, which document different components of the Cardano governance metadata system.
Developers are considering writing clearer documentation to explain how these related architectures should be interpreted and extended.
Two Cardano proposal documents have reached their milestones.
The summary also lists CIP-0204, titled "Holder Answers on Governance Actions," as one of the completed projects.
This specification describes a method that allows ADA holders to record their responses of "yes," "no," or "abstain" to governance actions via transaction metadata signed by their stake key.
These responses will provide a public record of holder preferences but will not replace the formal voting responsibilities of proxies, staking pool operators, or the Constitutional Committee.
Although the review milestone has been completed, CIP-0204 is still classified as Proposed in the repository.
The second item, CPS-0037, addresses the challenges developers face when designing applications and constructing transactions under Cardano’s minimum unspent transaction output requirements.
The Cardano problem statement document is used to record issues discussed by the community and potential future solutions. Completing this document alone will not change the network's minimum transaction output rules.
