3DPass is an open-source Layer 1 blockchain written in Rust and built on Substrate. It introduces a novel consensus mechanism called Proof of Scan, where miners validate by running recognition algorithms on 3D objects. Each object produces a reproducible cryptographic fingerprint (HASH ID) that is stored on-chain. If the same object is submitted again, the network rejects it, ensuring that only one of a kind assets can be registered. This approach enforces authenticity at the content level, something traditional file storage and NFT systems cannot achieve.
The features of 3DPass include: Proof of Scan consensus, enforced uniqueness of 3D objects, CPU-only mining with no pools, object tokenization through the 3DPRC-2 standard, EVM compatibility, native web and mobile wallets, and open-source community governance.
Features
- Proof of Scan consensus: miners validate by generating unique fingerprints of 3D objects instead of meaningless hash puzzles.
- Enforced uniqueness: duplicate objects are rejected at the protocol level, ensuring only one-of-a-kind assets can be registered.
- CPU-only mining without pools: energy-efficient, decentralized, and aligned with Satoshi’s “1 CPU = 1 vote” vision.
- 3DPRC-2 tokenization standard: links NFTs directly to object fingerprints for verifiable provenance.
- EVM compatibility: enables interaction with Ethereum-based smart contracts and cross-chain bridges.
- Native wallets: web and mobile apps allow uploading, transfers, and asset management.
