ProofSetu Protocol

ProofSetu Protocol is an open-source verifiable workflow proof layer built on Stellar/Soroban.

• Verify Sample: https://proof-setu-protocol.vercel.app/proof/sample
• 🎥 Demo Video: ProofSetu Protocol v0.3.0 — Stellar Testnet Proof Verification Demo

Current MVP Flow

1. Create a workflow proof record and SHA-256 document/event hash.
2. Submit or anchor the proof through the Stellar/Soroban testnet integration.
3. Retrieve the proof record from the deployed Soroban registry.
4. Verify the stored hash against the expected value.
5. Reject verification when the supplied hash does not match.
6. Inspect the public verification result and transaction evidence.

The current v0.3 flow includes a deployed Stellar testnet Soroban contract and verified create_proof, get_proof, and verify_proof behavior. Local hashing remains part of the client workflow, while testnet anchoring provides the external verification layer.

Problem

Important real-world work often depends on scattered proof across WhatsApp, email, PDFs, screenshots, spreadsheets, and internal tools.

This creates disputes, delays, weak auditability, and lack of trust between parties.

Examples:

• A freelancer says a milestone was completed.
• A client says an invoice was approved or not approved.
• An NGO wants to prove donation usage.
• A startup wants to prove grant deliverables.
• A hospital wants to prove that a claim document was submitted.
• An AI-assisted workflow needs an accountable decision trail.

Solution

ProofSetu Protocol creates verifiable proof records for real-world workflow events.

Each proof record can include:

• Proof ID
• Proof type
• Event title
• Short description
• Document or event hash
• Timestamp
• Creator wallet
• Network reference
• Verification status

The long-term goal is to anchor these proof records on Stellar/Soroban so anyone can verify that an event existed at a specific time without exposing private documents.

Why Stellar

Stellar provides fast, low-cost, open financial infrastructure suitable for real-world payment and trust workflows.

ProofSetu uses Stellar/Soroban to make workflow proof records verifiable, transparent, and ready to connect with future payment, milestone, invoice, escrow, remittance, or stablecoin settlement flows.

MVP Scope

The first version will include:

• Landing page
• Proof creation form
• Hash generation
• Local proof registry
• Public verification page
• Example proof records
• Stellar testnet integration roadmap
• Soroban proof registry contract roadmap

Use Cases

1. Freelancer milestone proof
2. NGO donation usage proof
3. Startup grant deliverable proof
4. Invoice approval proof
5. Hospital document submission proof
6. AI-assisted decision proof

Stellar Testnet Deployment

ProofSetu Protocol Phase 2 includes a deployed Soroban proof registry contract on Stellar testnet.

The contract has been built, tested locally, deployed to Stellar testnet, and invoked successfully.

Contract Details

• Network: Stellar testnet
• Contract ID: CD7VTK6VVMXCBWHOGPGWEHG3KFOLNSYMV3DNGK5BDMRWH74HGKLZRGGZ
• Wasm hash: 743718b322e6dc81af3677bafadd236f4a85a76c87171a7847c582f25b400166
• Deployer public address: GAT2L4GYPN2TST44AQA6QFVNWB4BUM7SXC73B4D5Y7PA4YRNHCLL

Deployment Transactions

• Deployment transaction: 5ee448eb186c966fe6965fa7282b94d78a96df4e596dd9d0f6326cf3d0f6261b
• Create proof transaction: 8a7fd049fcaf57e0c438a1b521b08cd30afe762cd6b74c172c302faccd98f132

Verified Testnet Flow

The deployed contract was tested successfully with a sample proof record.

• create_proof returned true
• get_proof returned the stored proof record
• verify_proof with correct hash returned true
• verify_proof with wrong hash returned false

Sample proof ID:

PS-TESTNET-001

Correct hash:

sample_testnet_hash_001

This confirms that ProofSetu Protocol can create, retrieve, and verify workflow proof records on Stellar testnet.
