In this hands-on lab, you will deploy smart contracts for IoT in IBM Blockchain, and connect MQTT devices to send IoT data to the blockchain using the IBM Watson IoT Platform. In an IoT context, data comes from "things" to private blockchain ledgers for inclusion in shared transactions with tamper-resistant records. Attend this lab and start creating a more efficient business network with the IBM Watson IoT Platform and IBM Blockchain.

Application invokes a transaction and passes data Transaction data is replicated to the validating peers in the blockchain fabric Peers pass transaction data to local chaincode program and run it. Chaincode programs are currently written in the language Go. Currently writing chaincode is very custom. Peer can store state information in the World State local database. Consensus algorithm runs and compares results across the peers. If > 50% of the peers agree, the changes to the world state database will be committed. Data passed to the Transaction is “locked” into a new block in the chain. Transactions are gathered into time windows for writing to the blockchain (default is 1 second).

Editor's Notes
- #5: 4
- #6: So Blockchain technology comprises these four main blocks, that can lead to increased efficiencies, and cost reduction across the business network. We will “unpack” CONSENSUS PRIVACY & SMART CONTRACT in the next couple of slides. Shared LEDGER has been already covered, and a SMART CONTRACT enables the business rules implied by the contract to be embedded in the Blockchain and executed with the transaction
- #7: This is the “BEFORE” picture representing the “status quo” for business networks. Each participant keeps their own ledger(s) which are updated to represent business transactions as they occur. This is EXPENSIVE due to duplication of effort and intermediaries adding margin for services. It is clearly INEFFICIENT, as the business conditions – the contract – is duplicated by every network participant It is also VULNERABLE because if a central system (e.g. Bank) is compromised due to an incidents this affects the whole business network. Incidents can include fraud, cyber attack or a simple mistake.
- #8: The novel Blockchain architecture give participants the ability to share a ledger which is updated every time a transaction occurs through peer to peer replication. Cryptography is used to ensure that network participants see only the parts of the ledger that are relevant to them, and that transactions are secure, authenticated and verifiable. Blockchain also allows the contract for asset transfer to be embedded in the transaction database determining the conditions under which the transaction can occur. Network participants agree how transactions are verified through consensus or similar mechanisms. Government oversight, compliance & audit can be part of the same network. Participants SAME AS BEFORE – this is not a disintermediation play CONSENSUS– means all participants agree that a transaction is valid PROVENANCE– means participants know where the asset came from and how it’s ownership has changed over time IMMUTABILITY– means no participant can tamper with a transaction once it’s agreed. If a transaction was in error then a NEW transaction must be used to reverse the error, with both visible FINALITY– means that there is ONE place to determine the ownership of an asset or completion of a transaction. This is the role of the SHARED LEDGER.
