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。
Marlowe Language Community Interest Companyは、Cardano上の金融契約DSLであるMarloweをV2へ更新するため、1,802,500 ADAを求めています。WP1ではMarlowe V2.0として、When/WhenAll、direct input indexing、exception handling、EntryDeposit、hash primitives、state compression、lazy closure、Plutus primitives活用、Runtime/TS-SDK/Playground更新を実装します。WP2では、Marlowe V2.1の設計・prototypeと、HTLC/Cardano Lightning integration、Marlowe State Channelを含むMarlowe L2 feasibility studyを行います。SIPOとしては、domain expertsにも扱いやすい形式検証可能な金融契約基盤という公共インフラ性と、Cardano DeFiの開発体験改善の可能性を評価します。一方で、過去のMarlowe adoptionから得た教訓、現在の実利用baseline、Aiken/Plutus/Tx3等との役割分担、V2.0実装とV2.1/L2研究の優先順位、150,000 ADA auditの独立性・公開範囲、Marlowe State Channelの安全性、Catalyst Fund 1300131とのscope separation、Treasury repayment Noに対する価格上昇・scope縮小時の保護を確認する必要があります。

Marlowe is a DSL designed specifically for financial contracts on Cardano — things like escrows, swaps, bonds, and payment schedules. The idea behind Marlowe is to make smart contract development accessible to non-programmers (financial professionals, lawyers, businesses) by abstracting away from the complexity of Plutus/Haskell and Aiken. In retrospect, the vision of non-technical financial professionals writing on-chain contracts was ahead of where both Cardano adoption and institutional blockchain engagement actually were at the time. With the rise of interest in DeFi on Cardano, now is the time to look again at Marlowe, since no other technology on Cardano (or indeed on other chains) has fully cracked what it was attempting — a genuinely accessible, formally verifiable financial contract tool for domain experts on a public blockchain. This proposal will modernise and update Marlowe to face the challenge of delivering Cardano DeFi. A group consisting of developers and users as well as core team members recently met over four meetings to design Marlowe V2 and the full report of this can be found here\* \*[*Marlowe language V2 Final Report*](https://docs.google.com/document/d/1Ex7SyN2hys8CD-hmULiwYNkKumGELlEAl15KWkMIpKs/edit?usp=sharing). The group envisaged improving Marlowe in a number of ways: simplifying some aspects, while making the language more expressive, scalable and secure. Proposals were categorised as to be implemented in Marlowe V2.0, to be elaborated for V2.1, or for future versions. The proposal requests Treasury funding to implement Marlowe V2.0: this consists of the on-chain,Marlowe validator, the off-chain Runtime, and the Marlowe tools and infrastructure making up the Marlowe Platform. The project will also support the design and prototype of Marlowe V2.1, as outlined in the report, and also conduct an in-depth feasibility study on Marlowe as the basis of a Cardano L2 solution - a Marlowe State Channel - a radical DeFi innovation.
