IBM Strategy for Blockchain

Enable untrusted parties to work together leveraging permissions and identity, to ensure data and transactions are protected and consistent

Regulated business environments without anonymous participants

Blockchain ≠

Open

Trusted

For Business

Blockchain needs to be built in a robust technology environment providing security, confidentiality, auditability, reliability and scalability

Open source, governance & ecosystem

One of 17 founding members of Hyperledger, a Linux Foundation Project

170+ cross-industry, global companies

Hyperledger Fabric, initially contributed by IBM, is in V1.0

Hyperledger Fabric – Architected for Performance & Scalability

Ordering service accepts endorsed transactions and orders them according to the plug-in consensus algorithm, then delivers them on the channel to connected peers.

Endorsers will each execute the proposed transaction. None of these executions will update the ledger

Committing Peers on the channel receive transactions, validate them and then commit to ledger

Ordering-Service

– Chaincode is installed on peers that need to access the worldstate

– Chaincode is instantiated on specific channels for specific peers

– Ledgers exist in the scope of a channel

• Ledgers can be shared across an entire network of peers

• Ledgers can be included only on a specific set of participants

– Peers can participate in multiple channels

– Concurrent execution for performance and scalability


Worldstate Database§ Pluggable worldstate database

• Default embedded key/value implementation using LevelDB

– Support for keyed queries, but cannot query on value

§ Support for Apache CouchDB

– Full query support on key and value (JSON documents)

– Meets a large range of chaincode, auditing, and reporting requirements

– Will support reporting and analytics via data replication to an analytics engine such as Spark

– Id/document data model compatible with existing chaincode key/value programming model


Hyperledger Composer: Accelerating Time to Value

§ A suite of high level application abstractions for business networks

§ Emphasis on business-centric vocabulary for quick solution creation

§ Reduce risk, and increase understanding and flexibility

§ Features– Model your business networks, test and expose via APIs– Applications invoke transactions to interact with business network– Integrate existing systems of record

§ Fully open and part of Linux Foundation Hyperledger
