zkFold Open Source Cardano Infrastructure 2026
zkFold
ID: 69fb54818a0de51b89857e11
Cardano needs open-source infrastructure that makes the network easier to use, more private, more interoperable with Bitcoin, and more scalable. zkFold proposes a 9-month open-source program to turn three advanced zkFold workstreams into public, auditable infrastructure that users and developers can evaluate, integrate, and build on. The proposal funds: 1. ZK Rollup: continue from the working testnet prototype toward transaction privacy, pre-mainnet optimization, mainnet launch, and maintained operation after launch. This gives Cardano practical private and scalable monetary transactions for institutional and high-throughput payment use cases. 2. Smart Wallet v2: a lower-cost smart contract, an open-source backend server component builders can reuse, and a simple send-to-email DApp that makes Cardano payments easier for newcomers, cheaper for users, and compatible with existing Cardano wallets from day one. 3. Bitcoin-Cardano Atomic Swaps: mainnet launch, open-source release, rare-edge-case recovery, and support for trustless BTC/Cardano swaps that complement Bitcoin bridge infrastructure and enable cross-chain DApps. The 9-month outcome is three mainnet launches: ZK Rollup mainnet, Smart Wallet v2/send-to-email mainnet, and Bitcoin-Cardano Atomic Swaps mainnet. All three workstreams will be open-source, with public documentation, milestone reports, and reviewable delivery evidence.
Scorecard
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).

Demand is mostly inferred from prototype usage rather than committed integrator partnerships. ZK Rollup is being scoped specifically to monetary transactions rather than general smart contracts, which is a sensible narrowing."
