概要
SIPO DRepレビュー支援用の日本語作業訳です。正式な内容はHydra Voting上の英語原文を参照してください。
TxPipeは、Cardanoのlightweight data nodeであるDolosを12か月保守・改善するため、540,750 ADAを求めています。Dolosは、フルCardano nodeを運用せずにchain dataへアクセスしたい開発者・事業者に対し、より軽量な同期・query interfacesを提供し、Pallas、UTxO RPC、tx3.landのJSON-RPC endpoints、TRP-based transaction resolution等の下流インフラを支えると説明されています。作業はdependency updates、protocol compatibility、performance improvements、bug fixing、documentation、issue triage、PR review、AI-friendly documentationで構成され、Blink Labsによるindependent reviewとUSD 105,000相当を上限とするrefund commitmentが示されています。SIPOとしては、軽量データアクセスとclient diversityの公共インフラ性を評価します。一方で、Dolosのproduction usage baseline、sync/query performance targets、supported query interfaces、Pallas/UTxO RPC/Oura/Tx3との責任分界、current/n-1/n+1 compatibility testの範囲、四半期ごとの具体成果、TxPipe複数提案を含むdelivery capacity、Blink Labs reviewの公開範囲、milestoneごとのUSD cap/refund timingを確認する必要があります。

This proposal requests 420,000 ADA (plus a 105,000 ADA contingency reserve) to fund **a part-time maintainer for Dolos **([https://github.com/txpipe/dolos](https://github.com/txpipe/dolos)) over 12 months at an annual rate of $105,000 USD, continuing the open-source maintenance initiative funded through Intersect's treasury process in the previous cycle. The new grant period would begin after the closure of the existing contract, ensuring uninterrupted maintenance coverage. Dolos is a lightweight Cardano data node built in Rust, designed to provide efficient access to chain data without the overhead of traditional full nodes and consuming a fraction of the resources. It connects directly to the Cardano network, indexes the full breadth of ledger primitives, and exposes five query interfaces including Mini-Blockfrost (HTTP), UTxO-RPC (gRPC), Mini-Kupo (pattern-matching UTxO queries), and an Ouroboros N2C unix socket compatible with Cardano-cli, Ogmios, and other existing tooling. With 939 commits, 80 releases, 129 stars, 51 forks, and 27 contributors, Dolos stands as a strong example of open-source development in the Cardano ecosystem. The project remains fully open-source and actively welcomes contributions from the broader developer community. The maintainer's work is organized across three areas, to ensure Dolos remains usable, reliable, and up to date as a lightweight, resource-efficient gateway to Cardano chain data: - Essential maintenance of the codebase, including dependency updates, Cardano protocol compatibility, performance improvements, bug fixing and documentation. - Community support includes issue triage, review of external contributions, enhancements driven by ecosystem feedback, and public communication with the developer community. - And as an important addition to the maintenance scope, we'll focus on upgrading Dolos compatibility with AI-driven development workflows by providing AI-friendly documentation and integration resources.
