STProof Physical Event Proof SOP

This directory contains the complete standard operating procedure for converting physical events to on-chain NFTs.

Process Overview

Event Design → Official Bulletin → Field Execution → Data Collection → Hash → OTS → IPFS → Three-Layer JSON → Mint

Detailed Steps

Phase Description
01 Event Design Define stamp theme, date, location, handwritten codes
02 Official Bulletin Capture release announcement with URL proof
03 Field Execution 5 mandatory photos + segmented video + GPS + weather
04 Data Collection Redact, rename, organize into 3-layer folder structure
05 Hash Calculation Compute SHA256 for every file
06 OTS Timestamp Generate OpenTimestamps proofs (Bitcoin-anchored)
07 IPFS Upload Upload public assets + OTS files to IPFS, record CIDs
08 Three-Layer JSON Generate JSON with L1/L2/L3 hash manifests
09 NFT Minting Mint NFT on OpenSea / STProof contract

Real Case

Core Principles

Public files = OTS + IPFS

Private files = SHA256 only (not uploaded)

L1 Public Common = Shared across all covers

L2 Independent Public = Unique per cover

L3 Private = Unique per cover, no original images

cid = CID of the file itself

timestamp_proof_cid = CID of the corresponding .ots file

Not the same, cannot be empty
