QR Data Model
/ Components and Binding
qr2layer Protocol
qr2layer functions as a native verification protocol that resolves QR nodes and queries on-chain data to provide users with verifiable trust evidence
Registry Program
A smart-contract state machine that binds the anchor hash of the tag to the object's on-chain identity and enforces lifecycle transitions
Object and Tag
A physical item equipped with a tamper-evident label containing a QR node. Each object is represented on-chain as a collection-verified ith immutable, content-addressed metadata
RW Applications
/ Designed for global real-world blockchain development
Object Registration
For each object, the issuer creates a digital asset and records the anchor hash in the registry program. Any subsequent scan in the mainnet resolves the QR node, reads the on-chain account, and displays issuer, state and provenance
Labeling
qr2layer protocol generates unique QR codes. The QR node is printed on the tagged object. The tagged object is sent until it is activated in the chain
Market Integrations
qr2layer can integrate across industries such as automotive, fashion, art, electronics, collectibles, linking each physical product to a unique on-chain identity. Its QR architecture ensures authenticity, provenance, and lifecycle traceability
Metadata
Object attributes (brand, model, serial, issuance date, evidence URIs) are stored as immutable, content-addressed metadata, ensuring that any change would alter the content hash and be detectable
Building the future of blockchain
qr2layer architecture creates a cryptographic bridge between physical anchors and on-chain identities, using a deterministic state machine, immutable metadata, and collection-verified assets to enforce authenticity at scale. Bloq operationalizes this by resolving the QR token nodes and rendering issuer, state, provenance, and proofs directly from the ledger
The blockchain's immutability transforms the tradable property, reducing risk, creating most valuable objects, and supporting the appreciation of real-world assets over time
