Marlowe V2

Simon Thompson

ID: 69fc8a71b05ff80adc7d5c4f

Marlowe is a DSL designed specifically for financial contracts on Cardano — escrows, swaps, bonds, payment schedules — making smart contract development accessible to non-programmers by abstracting away Plutus/Haskell and Aiken complexity. This proposal funds implementation of Marlowe V2.0 (on-chain validator, off-chain Runtime, tools and infrastructure), prototype of V2.1, and an in-depth feasibility study on Marlowe as a Cardano L2 state-channel solution.

Scorecard

13 of 19 criteria answered
Amber · 71%

How this score works

Each criterion is worth between 1 and 4 points. The score is the points earned out of the points on criteria that have been answered — shown as a percentage. Green is 75% or higher, Amber is 50–74%, and Red is below 50%.

Some criteria are checked automatically against the proposal data (open source, doxxed team, treasury return clauses, etc.). Others are human-judgment calls — value for money, public good, whether the deliverables are realistic. Those stay blank until a DRep ticks them.

Criteria can also be marked Not applicablewhen they don't fit the proposal — for example, "open source" doesn't apply to a DAO governance proposal with no software output. Those are excluded from the score entirely, neither helping nor hurting.

Green requires 80% coverage. If less than 80% of the applicable criteria (by points) have been answered, the verdict stays at Amber — "pending review" — even when every answered criterion passes. This proposal's coverage is currently 68% (13 of 19 applicable criteria answered).

The proposal text itself contains a direct acknowledgment of demand failure: '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.' Marlowe has been live on Cardano mainnet since 2023 — three years of opportunity for production adoption has passed without significant deployed user base materializing. The proposal does not name any production Marlowe contracts currently deployed, any committed institutional users for V2, or any Cardano-native organization currently building on Marlowe and waiting for V2 features. Demand is asserted by potential ('with the rise of interest in DeFi on Cardano, now is the time') rather than evidenced by named users. The proposer's framing is honest about this gap. The WP2 'Marlowe L2 state channel' feasibility study adds even more speculative scope on top of an already-demand-light core."
