How Provn Works

A streamlined protocol for cryptographic hashing and high-velocity settlement on Solana Mainnet-Beta.

Step 01

Hash Locally

Compute a SHA-256 hash client-side. Your raw data never leaves your infrastructure — zero exposure by design.

Privacy First

Step 02

Submit Claim

Send the hash to Provn via REST API or SDK. Choose Economy (batched) or Priority (direct) anchoring.

REST / SDK

Step 03

Settle on Solana

Provn anchors your proof to Solana Mainnet-Beta via SPL-Memo. Economy batches amortize fees across claims.

Solana Mainnet

Step 04

Verify Anytime

Anyone can independently verify the proof via our Explorer or API — no trust required, pure cryptographic math.

Public Audit

Developer Suite

Verify With Confidence

Every proof is independently verifiable. Launch an audit manually via our explorer, or integrate our REST API for automated verification.

Industrial Grade

Enterprise-Grade Trust Layer

Built for mission-critical applications that require absolute data integrity and verifiable history.

Permanent

Immutable Storage

SHA-256 hashes are permanently anchored to Solana, creating an unalterable record of data existence.

Global Verify

Global Accessibility

Verify proofs from anywhere using public Solana explorers or our universal hash lookup endpoint.

Priority <2s

Real-Time Settlement

Choose between batched Economy (free), Standard (~1–5s), or Priority (Jito bundle) settlement on Solana.

Batch Efficient

Merkle Batching

Multiple proofs are batched into a single Merkle root, amortizing settlement cost across the batch.

HTTP/REST

REST API & SDK

Integrate with a simple HTTP POST. Python and TypeScript examples included. Full OpenAPI spec available.
