Blockchain of Things & Large Scale Deployments of Blockchain
summary
Argues that constrained devices register sensor, serial and firmware data via LwM2M→MQTT microservices and publish content-addressed blobs to IPFS + IPNS hashes; demos cloning a repo by its CID and serving firmware over localhost HTTP so a Raspberry Pi OTA via HTTP can pull updates without central servers. Proposes a blockchain token that pays nodes for pinning with proof-of-replication token economics, warns full nodes and ledgers don't fit small devices, cites IOTA DAG pruning and notes zero-knowledge proofs for low-cost anonymous M2M transactions.
