Supply Chain Blockchain — Tracking, Provenance, Trust
WeiBlocks builds blockchain infrastructure for supply chains — product tracking, provenance verification, carbon credit tokenization, and document attestation. Permissioned and public chains.
Quick Answer
WeiBlocks builds supply chain blockchain solutions — product tracking from origin to consumer, provenance verification, certificate of authenticity, carbon credit tokenization, and document attestation. We deploy on permissioned chains (Hyperledger Fabric, Hedera) for enterprise consortia, and public chains (Ethereum, Polygon) when transparency is the goal. 255+ projects delivered including the Web3 Carbon Credit Marketplace for Hestiya (70+ verified carbon credit projects).
Common Challenges for logistics and supply chain teams
Single Source of Truth Across Parties
Multi-party supply chains struggle to agree on data. Each party has its own ERP, and reconciliation is expensive.
Provenance Verification
Counterfeit goods cost industries billions. Consumers want verifiable origin (e.g. organic, fair-trade, conflict-free) but trust each party's claim alone is weak.
Carbon Credit Double-Counting
Carbon credits get double-counted across registries. Tokenization on a transparent chain prevents this.
Document Fraud
Bills of lading, certificates of origin, inspection reports — all vulnerable to fraud. On-chain attestation makes tampering visible.
What We Build for This Vertical
Product Tracking on Public Chain
QR-coded products linked to on-chain provenance records. Each handoff stamped on-chain by the receiving party.
Permissioned Consortium Chains
Hyperledger Fabric or Hedera for enterprise consortia where data privacy matters but multi-party trust is needed.
Carbon Credit Tokenization
Tokenized carbon credits with verification oracles, retirement mechanisms, spot and P2P marketplaces. Built Hestiya's platform with 70+ verified projects.
Document Attestation
Hash-on-chain attestation of supply chain documents (bills of lading, certificates of origin, inspections). Forgery becomes immediately detectable.
IoT Integration
Sensor data (temperature, humidity, location) anchored on-chain for cold chain, pharmaceuticals, and high-value goods.
Multi-Party Workflow Orchestration
Smart contracts encoding multi-party workflows — payment on delivery, conditional release of funds, dispute resolution.
Compliance & Regulatory Considerations
Frameworks we design around when building for logistics and supply chain teams. We pair this technical work with your legal counsel — we're not a law firm.
- Industry-specific regulations (FDA for pharma, USDA for food, etc.)
- Data privacy across borders (GDPR, etc.)
- Anti-counterfeiting laws (each jurisdiction)
- Customs and trade compliance
- Carbon credit standards (Verra, Gold Standard, etc.)

Frequently Asked Questions
Should we use a permissioned chain or a public chain?
Permissioned (Hyperledger Fabric, Hedera, Quorum) when you need data privacy across a closed consortium of known parties. Public (Ethereum, Polygon) when transparency to outside parties (consumers, regulators) is the value proposition. Many real systems use both — permissioned for sensitive ops, public anchoring for verifiability.
How do IoT sensors connect to the blockchain?
Sensor data flows through an oracle (often Chainlink, Pyth, or custom) that signs the data and posts it on-chain. For tamper-resistance, we recommend signed sensors (private keys on the sensor itself), edge gateways with TPM modules, and multi-source corroboration. Architecture depends on threat model.
How does carbon credit tokenization prevent double-counting?
Each tokenized credit has a unique on-chain identifier mapped to the underlying registry (Verra, Gold Standard, etc.). When the credit is 'retired' (used as offset), the token is burned on-chain. Smart contracts ensure 1:1 correspondence between on-chain tokens and unretired registry credits.
Can blockchain replace our existing ERP?
No — blockchain complements ERPs, doesn't replace them. ERPs are still where the day-to-day operations run. Blockchain is the shared layer where multi-party agreement happens. Integration patterns matter (event-driven sync, periodic anchoring, etc.).
What does a supply chain blockchain project cost?
Product tracking MVP: $50K–$150K. Multi-party consortium platform: $150K–$500K. Carbon credit tokenization platform: $80K–$200K. IoT integration: $50K–$200K additional. Pricing depends on number of parties and integration complexity.
