Cardano Tessera Shows How Governance Can Move Beyond Yes-or-No Votes

Cardano developers have presented Tessera, an on-chain survey application built around CIP-0179, during Cardano Developers Office Hours #69. The session, led by Matthieu Pizenberg, focused on how Cardano can support transparent surveys and polls that record answers through transaction metadata.

Tessera Adds On-Chain Surveys to Cardano

Tessera allows users to create, browse and answer surveys using regular Cardano transactions. A participant connects a wallet, selects a survey, submits responses and records them through metadata that compatible tools can index and display.

The application supports several question formats, including single choice, multi-select, ranking, numeric ranges, points allocation and rating models. That makes it useful for questions where a binary governance vote cannot capture the full range of community preferences.

CIP-0179, titled “On-Chain Surveys and Polls,” defines a standardized transaction metadata format for creating, responding to and cancelling surveys under metadata label 17. The proposal is listed in the Metadata category and currently has Proposed status in the Cardano Improvement Proposal repository.

CIP-0179 Expands Governance Feedback

Cardano governance already includes info actions, but those are limited when a topic requires more than yes, no or abstain. CIP-0179 gives wallets, explorers, dashboards and indexers a shared format for reading survey data instead of leaving each project to design its own off-chain polling method.

The standard can be used for governance and non-governance feedback. Its documentation includes examples such as ranking candidates, polling candidate CIPs for hard-fork prioritization, collecting numeric preferences and voting on budget line items.

Tessera can also link surveys to governance actions for visibility. Surveys may be public, with responses visible as they are submitted, or sealed, with answers encrypted during the survey period and revealed after it ends. In the presentation, this was described as delayed disclosure, not permanent privacy.

Verifiable Results Create New Governance Workflows

Tessera includes export and verification features for survey results. Responses can be downloaded as CSV files, while a JSON artifact can provide the data used for tallying. For stake-weighted surveys, that artifact can include responder roles and the voting weight applied at the relevant snapshot.

The presentation also covered possible additions, including support for developer ecosystem surveys, multilingual survey content, optional free-text responses, question dependency logic and additional authentication methods. Pizenberg also discussed broader ideas such as topic-scoped delegation, where delegation could depend on the subject being decided.

Tessera does not replace Cardano’s formal governance process. Its role is narrower and more practical: it demonstrates how priorities, candidates, budget options and developer feedback can be captured in a format that other Cardano tools can read, export and verify. For a governance system now handling treasury decisions, protocol priorities and community elections, that gives Cardano a clearer way to measure sentiment before decisions reach the formal voting layer.
