Obsqra Cloud

Prover, RPC, zk multiprocessor, verifier contracts, and registries—composable for Starknet

Obsqra Prover Service (Stone execution proofs), first-party Starknet RPC at https://starknet.obsqra.fi/rpc, zk multiprocessor (composed agents), on-chain verifier contracts, and registries you can plug into. One place for proofs and chain access. Access will be gated by reputation-backed staking on zkde.fi: stake collateral as your subscription; longevity builds reputation and perks. Sign in with your Starknet wallet to get started.

We're early—Cloud runs on experimental infrastructure. Production products built on this stack are coming soon.

Dual-Proof Prover

STARK (Stone/Integrity, trustless) + Groth16 (Circom/Garaga, on-chain). STARK fact binding neutralizes Groth16 trusted setup. Partial success is valid.

Obsqra zk multiprocessor

Run composed agents: multiple processors in parallel, AND/OR decision logic, one API call.

Starknet RPC & node

First-party Starknet JSON-RPC at starknet.obsqra.fi/rpc (Sepolia). Standard methods, no API key for RPC. Same node our prover uses for verification—one vendor for proofs and chain.

Verifier contracts & registries

On-chain verifiers and registries (Fact Registry, model registry). Composable with your contracts.

Privacy proofs (Groth16/Garaga)

Confidential transfers, shielded pools, selective disclosure. Same API, same registry. Privacy is first-class in the stack.

Wallet identity

Reputation-backed staking (planned)

Stake collateral on zkde.fi—your stake is your subscription. As long as it's staked you have access. Longevity builds reputation and perks (limits, priority), tied to zkde.fi creditworthiness. Reputation-as-service loop.

Today: API key and pay-per-use. Planned: stake on zkde.fi for subscription; reputation unlocks higher limits and priority. Early-stage stack; production products soon.
