Blockchain for Industry
Straight facts for factories — English & Thai
This page explains what blockchain really offers in industrial settings—where it fits, where it doesn't, and how to deploy it without hype.
🔗 What blockchain is (and isn't)
✅ What it IS
- • A tamper-evident ledger shared across multiple parties
- • Records chained by cryptographic hashes; altering history becomes detectable
- • Works best when multiple organizations must share an audit trail
- • Ideal when no single party is fully trusted to maintain records
❌ What it's NOT
- • Not a high-performance database
- • Not a magic security layer
- • Not required for every "traceability" problem
- • Not a solution for single-organization data
✅ When it fits
🏭 Multi-company Processes
Suppliers ↔ Manufacturers ↔ Logistics ↔ Auditors
📋 Shared Audit Logs
Need for immutable records (compliance, recalls, provenance)
⚖️ Reduce Reconciliation
Cut disputes; each party sees the same state
🤖 Programmable Rules
Smart contracts that many parties must follow
🚩 When to avoid
❌ Single Owner Data
Internal-only data → normal DB + signatures/logging is simpler
⚡ High-Throughput Needs
Low-latency workloads → traditional databases/message buses
🛡️ GDPR/PDPA Data
Right to be Forgotten → keep on-chain hashes, raw data off-chain
🏛️ Unclear Governance
Who runs nodes, approves changes? → design governance first
🏭 Industrial use cases (practical)
📦 Supply-chain Provenance
Part/lot genealogy, anti-counterfeit seals, recall tracebacks
🔬 Quality & Calibration Proofs
Hash inspection reports, gauge readings, ISO 17025 certificates
🔧 Maintenance & Warranty
Signed service logs, parts authenticity, tamper-evident hours/cycles
🌱 Carbon/ESG Reporting
Tokenize batches/credits, prevent double counting, notarize sensor evidence
🔐 IoT Device Identity
Register device keys, record signed firmware updates
👥 eKYC/Access Logs
Cross-org visibility with minimal data disclosure
🔒 Public vs Permissioned
🏢 Permissioned
(e.g., Fabric/Corda/Quorum)
- • Known members
- • Configurable privacy
- • Predictable costs
- • Seconds-level finality
- • Typical for industry consortia
🌐 Public
(e.g., Ethereum)
- • Open participation
- • Strong decentralization
- • Variable fees/latency
- • Consider L2 solutions
- • Store hashes only, data off-chain
🚩 Red Flags - Don't Believe These
❌ "Immutability solves compliance completely"
It doesn't handle data minimization/erasure laws
❌ "Replace your ERP/DB with blockchain"
Blockchain complements, doesn't replace operational systems
❌ No governance model
No plan for member exit or key loss scenarios
❌ Storing personal data on-chain by default
Store hashes only, keep sensitive data off-chain
❌ No third-party audit of smart contracts
Unaudited code in production is dangerous
