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: built for Cross-Industry use in
regulated businesses from the ground up
Network tools
IBM provides tools for monitoring, logging, and
for compliance reasons backup/restore
Permissioned membership
Operate a trusted blockchain network with
known participants and regulatory oversight
Channels
Enable multi-party transactions with the privacy
and confidentiality needed for regulated
industries
Transaction history
Searchable transaction history for efficient
auditing and dispute resolution
Partitioned execution
Optimize network performance by separating
chaincode execution and transaction ordering
Modularity
Pluggable Consensus, Identity Management
Crypto and Ledger DB to dynamically grow a
business network
Confidentiality Production Workloads

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

11. © 2016 IBM Corporation 11
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

§ 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
