Tweag Core Cardano Infrastructure: Treasury Withdrawal 2026–2027

Summary

RCADA votes YES on Tweag Core Cardano Infrastructure: Treasury Withdrawal 2026–2027.

This is a cautious YES.

RCADA previously abstained on Tweag’s broader infrastructure proposal because it was too large, too broad, and too difficult to evaluate as a single all-or-nothing package. That earlier proposal bundled many work packages across multiple infrastructure areas, and RCADA wanted greater focus, clearer reviewability, better risk partitioning, and a more staged approach.

RCADA supports this proposal because it funds foundational public-good infrastructure for Cardano. Peras can improve finality, History Expiry can help reduce future SPO storage pressure, and conformance testing can improve the safety and correctness of major protocol upgrades.

The ask remains large at ₳18,263,496, so RCADA expects strong milestone reporting, public demos, independent review, IOG code review, transparent delivery evidence, and responsible return of unused funds.

Key Considerations

This proposal requests ₳18,263,496, equivalent to approximately $4,565,874 at $0.25 per ADA.
The proposal is focused on three work packages: Peras v1, History Expiry, and Conformance Testing.
The scope is narrower and more reviewable than Tweag’s earlier broader infrastructure proposal.
Peras aims to support faster finality, described in the proposal as approximately 2 minutes compared with roughly 12 minutes today.
History Expiry is relevant for SPO sustainability because higher throughput may increase storage demands.
Conformance testing supports safer deployment of complex protocol upgrades such as Peras and Leios.
Tweag has a long history of Cardano core infrastructure work.
The proposal includes open-source deliverables and public tracking.
Intersect is requested to serve as proposal and contract administrator.
The proposal includes third-party assurance, IOG code review, No Witness Labs validation, public demos, and smart-contract-based fund administration.
The proposal still carries risks due to size, bundling, prior Treasury funding, and dependency on later governance or hard-fork activation.

What this action does

This Treasury Withdrawal proposal funds Tweag by Modus Create to deliver three Cardano core infrastructure work packages over 2026–2027.

Work Package 1 — Peras v1

The Peras work package focuses on moving Peras toward mainnet readiness. It includes:

production cryptography;
KillSwitch functionality;
mainnet readiness work;
hard-fork readiness;
support and maintenance;
merged code;
reproducible releases;
runbooks;
benchmarks;
governance-action packages where needed.

Peras is intended to improve Cardano finality, with the proposal describing a target of approximately 2-minute finality compared with roughly 12 minutes today.

Work Package 2 — History Expiry

The History Expiry work package focuses on partial-history nodes to reduce long-term storage requirements for stake pool operators.

This is relevant because future throughput improvements, including Leios, could increase disk usage. History Expiry is intended to help preserve sustainable node operation and reduce centralising pressure on SPOs.

Work Package 3 — Conformance Testing

The Conformance Testing work package extends the CTC framework for Peras and Leios.

This work supports:

correctness testing;
mutation testing;
adversarial fork simulation;
audit infrastructure;
validation of complex protocol changes before deployment.

The proposal presents these three work packages as an interdependent delivery pipeline rather than a modular menu.

RCADA Rationale

RCADA votes YES on Tweag Core Cardano Infrastructure: Treasury Withdrawal 2026–2027.

This is a cautious YES.

This revised proposal is materially different. It is narrower, smaller, and more focused on three critical work packages: Peras v1, History Expiry, and Conformance Testing for Peras and Leios. The proposal requests ₳18,263,496 to support core infrastructure delivery across 2026–2027, with the primary focus on bringing Peras toward mainnet readiness, reducing future SPO storage pressure through History Expiry, and strengthening correctness testing for major protocol upgrades.

RCADA supports the direction because this is foundational public-good infrastructure. Peras, History Expiry, and conformance testing are not narrow commercial products. They are core protocol and network-resilience work that can improve Cardano’s long-term scalability, finality, correctness, and operational sustainability.

The Peras work is especially important because faster finality can improve the user and application experience. The proposal describes Peras as targeting approximately 2-minute finality, compared with roughly 12 minutes today. Moving this work toward production-grade mainnet readiness, including real cryptography, operational tooling, KillSwitch functionality, hard-fork readiness, support, and maintenance, is a reasonable use of Treasury funding if delivered with strong accountability.

RCADA also sees History Expiry as important for decentralisation and SPO sustainability. As Cardano moves toward higher throughput through future upgrades such as Leios, storage growth can become a real burden for stake pool operators. The proposal notes that higher throughput could significantly increase SPO disk usage and that partial-history nodes can help reduce long-term storage costs. For RCADA, this is directly relevant because infrastructure improvements should not make participation harder for smaller or independent operators.

The conformance testing work also strengthens the proposal. Major protocol upgrades require careful validation. Extending the CTC framework for Peras and Leios, including correctness scaffolding, adversarial testing, mutation testing, and audit infrastructure, helps reduce the risk of deploying complex changes to mainnet.

RCADA also recognises Tweag’s long history in Cardano core infrastructure. The proposal states that Tweag has been engaged with Cardano since January 2018, including work leading consensus and ledger teams, implementing Ouroboros Genesis, and contributing to Peras design. That track record gives this proposal more credibility than a greenfield infrastructure request.

The governance and accountability framework is also materially stronger than many Treasury proposals. The proposal includes Intersect administration, a written legal contract with Cardano Development Holdings, milestone-based fixed-price contracts where scope is well defined, public transaction metadata, third-party assurance, mandatory IOG code review, independent validation by No Witness Labs, Intersect delivery assurance, smart-contract-based budget management, external oversight, auto-abstain delegation, no SPO delegation, public demos at least every two months, refund of undisbursed funds, and proportional return of unused funds in the event of partial delivery or scope reduction.

However, RCADA’s support is not unconditional.

The ask remains large. ₳18,263,496 is a significant Treasury withdrawal, and core infrastructure work should be held to a high standard of public reporting, milestone clarity, and delivery evidence. RCADA expects transparent updates showing progress against Peras readiness, History Expiry implementation, conformance testing milestones, review outcomes, risks, and any funds returned.

RCADA also notes that some benefits depend on later governance, hard-fork readiness, and ecosystem activation. The proposal addresses this by committing to “ready-for-activation” deliverables such as merged code, reproducible releases, runbooks, benchmarks, and governance-action packages. That is a reasonable distinction, but the community should still track whether this work ultimately translates into mainnet value.

The proposal is still bundled, though much less so than the previous version. RCADA would generally prefer maximum voting granularity, but in this case the three work packages are more tightly connected and focused on critical protocol delivery, correctness validation, and SPO sustainability. This makes the bundling more acceptable than in the prior broader proposal.

RCADA also notes Tweag’s prior Treasury allocation of ₳11,070,322.68. Continued support should be tied to clear evidence that prior and current Treasury-funded work is advancing toward public mainnet benefit.

For these reasons, RCADA votes YES. This proposal is closer to the narrower, staged, critical-path infrastructure funding model that RCADA asked for previously. RCADA supports funding core open-source Cardano infrastructure while expecting strong milestone reporting, public demos, independent review, transparent delivery evidence, and responsible return of unused funds.
