Blockchain & Internet of Things (IoT)
Smart contracts, supply-chain traceability, asset tokenisation and enterprise IoT platforms. Gateways, edge computing, MQTT/LoRaWAN protocols, OTA firmware and real-time monitoring dashboards.
What we deliver
- Smart contract development on EVM (Solidity) and permissioned chains (Hyperledger Fabric, Besu)
- Supply chain traceability with on-chain hashing and multi-party verification
- Asset tokenization: fungible tokens (ERC-20) and non-fungible tokens (ERC-721/1155)
- IoT gateway design and edge computing architectures with local processing
- Protocol integration: MQTT, LoRaWAN, CoAP, and OPC-UA for industrial environments
- OTA firmware management with full device lifecycle control and secure rollback
- Real-time monitoring dashboards with threshold alerting and time-series history
- IoT data anchoring on blockchain for immutable audit trails and regulatory compliance
When you need it
Manufacturer with limited supply chain visibility
You can't prove component origin to enterprise buyers or retailers. You need a system that records every physical handoff on a shared, tamper-proof ledger — cutting dispute resolution time and audit costs.
Company looking to tokenize physical assets or project shares
You want to fractionalize ownership of an asset — equipment, a receivables portfolio, a real estate project — and distribute tokens to investors. You need secure contracts, a management portal, and regulatory alignment.
Industrial plant that needs remote monitoring
Machines and sensors on the floor aren't feeding useful data into your ERP or operations dashboard. You need ruggedized gateways, reliable LPWAN protocols, and a real-time view of production KPIs and anomalies.
Logistics operator managing cold chain compliance
Shipping pharmaceuticals or perishable food requires certified records of temperature and humidity at every step. You need IoT sensors integrated with blockchain to produce tamper-proof evidence for clients and regulators.
Frequently asked questions
How long does it take to deploy a smart contract to production?
It depends on business logic complexity and the target chain. A standard ERC-20 contract with a basic audit takes 3-4 weeks. A governance or multi-sig system on a permissioned chain takes 8-12 weeks. Code audit is not optional — it accounts for 20-30% of total delivery time.
Should I use a public blockchain or a permissioned one?
If external parties — customers, certification bodies — need to read the ledger and you don't want to run infrastructure, a public chain or L2 is faster and cheaper. If data is confidential and all nodes belong to you or known partners, Hyperledger Fabric or Besu give you more control. The key question is: who reads the ledger and how often?
Will your platform work with our existing IoT devices?
Usually yes. We integrate with devices that expose MQTT, Modbus, OPC-UA, or REST. If the firmware is proprietary and locked, an edge gateway acts as a protocol translator. We assess compatibility in a 2-4 hour technical session before any commitment.
How does large-scale OTA firmware update work?
We use a managed FOTA server with cryptographic package signing, progressive rollout by device groups, and automatic rollback on failure. On LoRaWAN networks, bandwidth limits slow things down significantly — a few-KB update can take hours. Plan updates outside operational windows.
What are the ongoing costs of running a permissioned blockchain?
Main recurring costs are validator node infrastructure (cloud or on-premise), monitoring, and consensus upgrade work. On managed cloud, a 3-node network with standard availability runs in the hundreds of euros per month. We size it based on your expected daily transaction volume.
