Cardano's November 1 improvement proposal roundup features a draft for common compliance requirements on regulated stablecoins and a proposal for quantum-resistant signature verification in Plutus. The signature proposal is not an activated security upgrade, and adding its verification functions would need a network hard fork.
Cardano has outlined new proposals on regulated stablecoins and quantum-resistant signatures. The weekly roundup, compiled by CIP editor Robert Phair, also covered one governance issue under review and two items that reached completion.
Stablecoin draft seeks shared compliance requirements
The first submission aims to standardize regulated stablecoins built on Cardano's CIP-0113 programmable-token framework. Its problem statement, filed under pull request 1266, argues that individual programmable stablecoins currently need separate integrations because their transaction requirements can differ.
The author proposes a shared set of requirements that issuers across different jurisdictions could use. A common integration would let wallet developers, exchanges and other infrastructure providers support multiple qualifying tokens without rebuilding their systems for every issuer.
However, the proposal remains open for discussion. Its author has asked issuers for feedback on regulatory requirements, and infrastructure providers for input on whether a shared standard would work in practice.
Quantum-safe signatures enter CIP review
A separate submission from Quantova Inc. proposes CIP-0206, which introduces two signature verification functions for Plutus, Cardano's smart contract platform. The authors selected ML-DSA and SLH-DSA, two algorithms the U.S. National Institute of Standards and Technology standardized under FIPS 204 and FIPS 205.
Quantova has supplied reference code, encoding rules and test cases. Even so, adding the functions to Cardano's consensus-critical Plutus evaluator would require a network hard fork, so the proposal is not an activated security upgrade or a change to existing wallet signatures.
Governance metadata and completed documents
Elsewhere, contributors in GitHub issue 1302 questioned why the CIP-0169 governance metadata schema no longer listed CIP-0008 as an accepted witness algorithm. The change raised concerns about compatibility with existing hardware-wallet signing methods, and reviewers examined whether the earlier entry should be restored.
Two documents reached completion. CIP-0204 describes a way for ADA holders to record Yes, No or Abstain responses to governance actions through metadata signed with their stake keys, yet it remains classified as Proposed in the repository. The second, CPS-0037, documents difficulties that Cardano's minimum unspent transaction output requirement creates for developers, and completing it does not change the network's output rules.
