6.15 First Speaker: Gari Singh – CTO, IBM Blockchain Platform, IBM Cloud and Cognitive. As a Distinguished Engineer and CTO of IBM Blockchain, Gari Singh has provided the technical guidance and leadership that has made IBM a leader in the blockchain space. He is responsible for IBM’s core blockchain platform offerings.

Gari is also a core maintainer and contributor to Hyperledger Fabric, an open-source blockchain technology designed to meet the needs of businesses.

Gari started the Presentation by advising that he is in charge of the whole Engineering Team,  the Support Team and the Lab Services. The IBM Blockchain had started in 2015 as Gamification for IBM Cloud, for which they considered Tokens,  and use of Etherium. However Etherium was not well suited to IBM Projects as it was difficult to change the Rules. Bitcoin was better, so  Etherium was replaced by IBM Open Blockchain, using the Linux Hyperledger Fabric as the IBM  Blockchain Platform.

This provided Scaleability, Transaction Endorsement (who can endorse, validate , signatures.)

Hyperledger Fabric also allows an organization to simultaneously participate in multiple, separate blockchain networks via channels (chains). The Hyperledger Network comprises a set of Nodes (the most common is Peer), connected by Channels. By joining multiple Channels, an organization can participate in a Network of Networks

Each Channel’s genesis block, the first block in the chain, contains the channel’s initial configuration


The  Hyperledger Network is governed using Policies which cover the organisations in the Consortium,  and using Configuration Transactions which are held in Configuration Blocks, with no other transactions. Ordering & Batching are separate.


Hyperledger Fabric has a ledger subsystem comprising two components: the World State and the Transaction Log. Each participant has a copy of the ledger to every Hyperledger Fabric network they belong to. The World State component describes the state of the ledger at a given point in time.

The X. 509 public key infrastructure (PKI) standard is used to verify that a public key belongs to the user, computer or service identity contained within the certificate.

Identity: Every component has the X509 issued by the organisation’s Certification Authority. The user role determines the level of access.


The IBM Hyperledger Smart Contract is the code (chaincode} that applications interact with to read and update data on the blockchain ledger. A smart contract can turn business logic into an executable program that is agreed to and verified by all members of a blockchain network. This is done before Ordering. The signatures are obtained, then passed to Ordering (ORG(s)), who broadcast to Peers.

This may apply to multiple Networks, e.g. IBM Hyperledger, Walmart


A new initiative, still in progress, is the adoption of Identity Mixer, which has cryptographic protocols that protect the privacy of users when signing, authenticating, and during the transfer of certified attributes. Identity Mixer has a trust model and security guarantees similar to what is ensured by standard X.509 certificates but with underlying cryptographic algorithms that efficiently provide advanced privacy features such as “unlinkability” and minimal attribute disclosure

The Fabric Identity Mixer technology is built from a blind signature scheme that supports multiple messages and efficient zero-knowledge proofs of possession of a signature.


The Hyperledger Fabric Client software development kit (SDK) provides a way to use a library of APIs to support developing smart contracts and enable the integration between Client applications and the network.


Programming Smart Contracts: Lifecycle of an Object

A smart contract defines the transaction logic that controls the lifecycle of a business object contained in the world state.

World state stores the latest state of any object while the blockchain stores all the history of the object from its creation to its current state.

In Fabric, a smart contract is packaged into the chaincode and then the chaincode is deployed to a blockchain network..

Multiple smart contracts can be defined within the same chaincode.

There can be a chaincode for a Vehicle and it can have multiple smart contracts such as Car Contract, Bike Contract, and Truck Contract. Lifecycle of an Object can include Create Car, Query Car, Scrap Car.

Example: Decentralised applications (Dapps) for Asset Transfer.

Fabric offers the ability to create private data collections, which allow a defined subset of organizations on a channel the ability to endorse, commit, or query private data without having to create a separate channel. The actual private data is sent peer-to-peer via gossip protocol to only the organization(s) authorized to see it. A hash of that data, which is endorsed, ordered, and written to the ledgers of every peer on the channel,  serves as evidence of the transaction and is used for state validation and can be used for audit purposes. Endorsement policies define which organizations must sign a transaction to declare the transaction valid. Endorsement policies can be on Collections level or Individual Key level. The Bid-Ask prices remain private.



  • Channels don’t know about each other. Fabric policies represent how members come to agreement on accepting or rejecting changes to the network, a channel, or a smart contract. Policies are agreed to by the consortium members when a network is originally configured, but they can also be modified as the network evolves. For example, they describe the criteria for adding or removing members from a channel, change how blocks are formed, or specify the number of organizations required to endorse a smart contract.
  • Tradelines – 98 CTOs – mainly shippers, e.g. Dept of Home Affairs Compliance, Cargo Security. Where do people want to run the Node? In the early days it was all in IBM Cloud, now can run from anywhere.
  • Use cases – Payments – Projects. IBM will never offer cryptocurrency
  • Use cases for Ordering – run for others – IBM offer this

Life Digitised with Blockchain – Life Chain

AID:Tech – Using Blockchain technology, AID:Tech revolutionises how governments, corporates and NGOs deliver digital entitlements across the world.

Decentralised ID – IBM & Growth Tech (small Company) – Decentralized identity puts that power and responsibility back in the hands of the individual, giving them the ability to control and protection their own personal information. This concept is made possible by the decentralized nature of blockchain and the trust created by consensus algorithms.


International Social Security Association (ISSA) promotes excellence in social security administration through professional guidelines, expert knowledge, services and support to enable its members to develop dynamic social security systems and policy throughout the world.


2019 Year in Review – Use Cases

RSBN IBM Ethical Mineral Sourcing Blockchain – The Responsible Sourcing Blockchain Network (RSBN), an international consortium built on Hyperledger Fabric, to protect against exploitative mining practices – Cobalt – No child labour


Brazil – Network of Networks – Vale, CIP, TecBan – (Used by Banks to avoid fraud, Renting machine for ATMs, Tinder for money) moved to Blockchain.


AMIS – Proof of Auto Insurance – Mexico. Only one in three vehicles were insured in the country, according to Mexican insurance industry association AMIS, which now has an  IBM Hyperledger Fabric blockchain. This allows insurers to share information anonymously and fluidly. This data then operates as a historical record that all users can tap into and trust.


Mediaocean & AAIS  – Mediaocean automates every aspect of the advertising workflow – from planning, buying and selling, to analyzing and optimizing, to invoicing and payments.

The Australasian Association for Information Systems (AAIS) is a Chapter of the Association for Information Systems (AIS) serving Australia, New Zealand and the South Pacific.
