Extropy has built a focused practice around zero-knowledge proof systems, spanning education, security auditing, and original research. Its ZK auditing work targets vulnerability classes specific to proof systems — under-constrained circuits, finite field arithmetic overflows, and soundness failures that allow false proofs to pass — covering zkVMs as well as individual protocols. The firm has collaborated on ZK projects with ecosystems including StarkNet and MINA, and has partnered with Encode Club on a zkML Bootcamp covering the intersection of zero-knowledge proofs and machine learning. Extropy Academy offers dedicated ZK courses and workshops through its platform at academy.extropy.io. The firm's research output includes technical publications on quantum cryptography threats and EIP analyses that touch on cryptographic protocol evolution. Founded in Oxford in 2015, Extropy draws on proximity to academic cryptography research and team backgrounds in formal verification and applied cryptography to support organisations building on ZK infrastructure across multiple blockchain ecosystems.

Orbiter Finance uses zero-knowledge cryptography as a foundational layer for its cross-chain arbitration and dispute resolution system. The ZK-SPV (Zero-Knowledge Simple Payment Verification) component authenticates transaction existence, timing, and rule compliance across heterogeneous chains without requiring a full node, enabling trustless dispute resolution without relying on an oracle or centralized relayer. Beyond the bridge, Orbiter has developed the zkProver, which aggregates up to 128 ERC-20 user-operation signature verifications into a single ZK proof, reducing average gas consumption by roughly 58% compared to standard account-abstraction accounts. The Aggregated zkProver extends this into a recursive SNARK scheme allowing ZK rollups to participate in shared proof aggregation, launched in Q4 2024. The team also co-authored a zero-knowledge research paper with the Ethereum Foundation in 2024.

RISC Zero is a zero-knowledge computing platform that enables developers to generate cryptographic proofs for arbitrary Rust programs without requiring ZK mathematics expertise. The zkVM runs programs compiled to the RISC-V instruction set and produces zk-STARK proofs attesting to correct computation, which are then aggregated and converted to Groth16 SNARKs for on-chain use. R0VM 2.0, released in April 2025, cut Ethereum block proving time from around 35 minutes to 44 seconds and reduced proof costs roughly 5x. Boundless, a decentralized proof marketplace, launched Mainnet Beta in July 2025 on Base and processed 542.7 trillion RISC-V cycles across 399,000 fulfilled orders by mid-August 2025. Multi-chain support includes a Solana Groth16 verifier using native alt-bn254 system calls, audited by Veridise. Wormhole, Citrea, and Nethermind each integrate RISC Zero for cross-chain verification and validity proofs.

Darklake Labs built Zyga, a dynamic zero-knowledge proof system designed natively for Solana's 400-millisecond block times. Unlike ZK systems built for Ethereum, Zyga introduced proof reusability — updating live public data like oracle feeds and lending rates without invalidating existing proofs. This made it practical for the dynamic conditions of active DeFi protocols, where parameters shift continuously between order submission and execution. The Zyga proof system was documented in a pre-print on the IACR ePrint Archive (eprint.iacr.org/2025/1802), covering its one-sided encoding mechanism, security proofs under standard cryptographic assumptions, and Solana performance analysis. The team maintained research partnerships with two Brazilian universities and held a patent application in process. Following Darklake's acquisition by SOL Strategies in April 2026, Zyga is now being developed as the privacy layer for institutional Solana participants.

Privacy Cash is built around Groth16 zero-knowledge proofs generated entirely client-side in the user's browser, ensuring that relayers never see the recipient address or the amount before cryptographic commitment. The circuits are compiled via Circom v2.2.2, with the Solana on-chain program written in Rust using the Anchor framework, and the entire codebase—including ZK circuits and developer SDK—is open-sourced and formally verified. As of mid-2026, the protocol has undergone 20 security audits across its Solana, Base, and EVM implementations, with formal verification of the Solana program performed by Veridise, a firm specializing in ZK circuit and smart contract verification. The deployed program binary is anchored to a publicly posted on-chain hash, allowing independent verification that the running code matches the audited source.

In April 2026, SOL Strategies acquired Darklake Labs for $1.2 million, gaining ownership of Zyga, a zero-knowledge proof system built for Solana. Zyga allows parties to verify trade constraints and collateralization ratios without revealing underlying position data, settling in a single transaction. The system is designed to enable verifiable compliance for institutional DeFi without exposing sensitive trading information. Zyga is positioned as a building block for privacy-preserving financial applications on Solana, particularly in institutional trading and collateralized lending contexts. The acquisition sits alongside SOL Strategies' purchase of Houdini Swap, a privacy-focused cross-chain aggregator, extending the company's portfolio into privacy and verifiability at the protocol level. Together, these acquisitions reflect a broader thesis around trust-minimized infrastructure for institutional participants on Solana.

Cloak's withdrawal mechanism relies on Groth16 zero-knowledge proofs generated in the user's browser, enabling holders of encrypted pool notes to prove ownership of a valid balance without disclosing which specific note they hold or how much it contains. When a user initiates a withdrawal, this ZK proof is passed to a permissionless miner network that submits and signs the transaction on the user's behalf, ensuring the originating wallet address never appears in the on-chain withdrawal record. The Groth16 proving scheme is verified directly on Solana's native execution environment, enabling settlement without the multi-minute delays common in Ethereum-based ZK privacy protocols. This architecture achieves what Cloak terms unlinkability: an on-chain observer sees only a pool-to-recipient transaction with no ability to associate a deposit address, transferred amount, or timing with any particular withdrawal. Miners additionally generate decoy transactions that are cryptographically indistinguishable from genuine withdrawals, preventing statistical analysis from narrowing the anonymity set when real user volume is low. The combination of in-browser proof generation, on-chain Groth16 verification, and miner-generated decoys represents a layered application of zero-knowledge cryptography to the practical privacy needs of Solana's stablecoin economy.

Automata Network integrates zero-knowledge virtual machines to compress hardware attestation quotes into affordable on-chain proofs. Without ZK compression, verifying a raw TEE attestation report on-chain can cost millions of gas; integrations with RISC Zero, Succinct, and Brevis reduce that cost to practical levels without sacrificing the cryptographic guarantees provided by the underlying hardware. This positions Automata at the intersection of TEE-based and ZK-based verification approaches. The practical result is that rollups and decentralized applications can access hardware-attested computation proofs at scale without prohibitive costs. Scroll and Linea use the Multi-Prover AVS, which combines TEE-based proving with ZK compression, as part of their path toward Stage 2 decentralization. Enhanced multi-prover support with expanded ZK integration shipped in January 2026.

Amadeus Protocol has established a partnership with zkVerify, a zero-knowledge verification layer developed by Horizon Labs, to enable cryptographic proof of AI computation correctness. The planned integration creates a proof settlement bridge between the two networks, allowing AI training and inference workloads to receive zk-proof validation. Phase 1 covers basic uPoW job validation, while Phase 2 scales to comprehensive AI computation verification, with the full rollout spanning Q4 2025 through Q2 2026. The zk-proof integration supports enterprise compliance use cases including provenance attestation, geofencing, and licensing verification. KZG-based proofs also enable cross-chain interoperability with EVM-compatible networks through the same verification layer. For agent operations requiring confidentiality, Amadeus supplements zk-proofs with Trusted Execution Environments, which protect sensitive inputs and intermediate states while still producing verifiable attestations of correct execution.
