Designed for SPb BlockChain Community Meetup - Aug 24, 2017

1. Distributed Ledger Technologies for Internet of Things
DLT4IoT

2. Internet of Things
● Devices, sensors
● Gateways
● Servers

3. Internet of Everything

4. IoT frameworks
● DeviceHive
● Amazon IoT
● IBM Watson
● Intel IoT Gateway
● Android Things
● Kaa
● thingsboard.io
● Protocols & Standards
○ MQTT, CoAP, STOMP, XMPP, Websockets
○ IPv6, 6LoWPAN, BLE, ZigBee
● Hardware
○ Arduino
○ Raspberry
○ Intel Edison
○ ESP8266
● System integration
○ AMQP, Kafka, Cassandra, SQL, HDFS
● Clouds
○ AWS, GCE, Azure, Bluemix

5. Blockchain IoT use cases and opportunities
● Security
● Real-time visibility of shipments
● Asset lifecycle management
● Device-to-device payments
● Smart Contracts and Oracles

6. IoT security with Blockchain
● Event and notification messages as blockchain transactions
● Data provenance
○ Validate device with a hash of its identity
○ Include identity hash in measurement
○ Record measurement in DLT
● Data quality
○ Maintain hashes of calibration records
● Data security
○ Integrity - maintain hashes of firmware records
○ Availability - DLT are robust
○ Non-repudiation - DLT are immutable

7. Real-time visibility of shipments
● Blockchain provides each participant end-to-end visibility based on their level of
permission
● Each participant in a supply chain ecosystem can view the progress of goods through the
supply chain, status of customs documents, or view bills of lading and other data.
● Real time exchange of original supply chain events and documents.
● No one party can modify, delete or even append any record without the consensus from
others on the network.
● Reduce fraud and errors, reduce the time products spend in the transit and shipping
process, improve inventory management and ultimately reduce waste and cost.

8. Asset lifecycle management
● Asset digitalisation
● Parts history and provenance
● Maintenance and repair history
● Damage events
● Transfer of ownership

9. Device-2-Device communications
● Distributed Internet of autonomous devices
● Identity management
● Micropayments
● Offline functionality

10. Smart Contracts and Oracles
● Telematic Insurance. Data from IoT devices and sensors triggers
insurance cases
● Fraud prevention. Similar to the shipment case - sensor data helps
finding fraud patterns.

11. IoT Blockchain challenges
● Scalability
○ Bitcoin SPW, Ethereum Light Client Protocol
○ Permissioned blockchains
○ IOTA Tangle
● Processing power and time
○ Consensus algorithms
○ Special hardware
○ Semi-decentralized architectures
○ Permissioned blockchains
● Storage
○ No central server
○ DHT (Kademlia, Chord)
○ Storage nodes
● Offline functioning
○ IOTA Tangle

12. DeviceHive
● Open source and device agnostic
● Supported by DataArt IoT practice
● Analytics, Machine Learning,
Reporting
● Scalability in Cloud
● IoT toolkit for Devices and
Gateways
