AM1540B - Connected Vehicle Identity Management Using Blockchain

In the mobility world, vehicle identity management on blockchain is the foundation for the IoT connected vehicle ecosystem delivering trust, privacy, transparency, faster transactions, lower costs, and security to the marketplace and it's participants.

This session covers: the connected vehicle ecosystem model and use cases, vehicle identity requirements, the new MOBI vehicle identity standard ( the Mobility Open Blockchain Initiative ), vehicle wallet, identity and privacy strategies, a live demo of a prototype vehicle identity service implemented with a Hyperledger Fabric blockchain supporting the MOBI VID standard, key Hyperledger features, smart contract and API interfaces, related data models, sample transactions and a summary of next steps in connected vehicle identity on blockchains. We'll leave time for questions.

Key Takeaway 1

understand how the MOBI Vehicle Identity standard for blockchain supports a trusted, connected vehicle ecosystem

Key Takeaway 2

discover key Hyperledger Fabric blockchain features that support identity, privacy, transparency, trust and scalability

Key Takeaway 3

learn what a vehicle identity blockchain service is and the steps to build it

Session I - Enterprise Blockchain Concepts & Value

• Enterprise Blockchain solutions are a strategic investment for an organization. They are also different than public blockchains.

• This session presents the basic concepts of Enterprise Blockchain: organizations, consortiums, identity, wallets, membership, authentication, roles, abac – account-based access control, logical and physical networks, digital assets, distributed ledgers, peers, orderers, smart contracts, consensus, transactions, events, shared data, data privacy, data views, token reward systems and payment systems.

• The session also references different organization contexts for Enterprise Blockchain ( Supply Chain, Finance, Public sector, Healthcare etc ) as well as potential regulatory impacts of GDPR, CCPA and other regulations.

• Re-think and re-engineer how a network works. It’s more than just blockchain technology. Often Big Data, IoT ( Internet of Things ), Machine Learning, Automation and other technologies are part of the new solution as well. A few sample use cases for Enterprise Blockchains are reviewed focusing on how they deliver value for the respective organizations.

• Summary -
• Key Takeaway 1
Understand the key features of Enterprise Blockchains compared to Public Blockchain

• Key Takeaway 2
• See how smart contracts automate transactions across a network in real time

• Key Takeaway 3
• Learn how Enterprise Blockchain networks have changed business operations

Basic blockchains ( DLT )

1. Peer Network - host organizations: each maintain a copy of shared ledger in synch using smart contracts
2. Immutable, shared ledger - chain of write-only transaction blocks ordered by date distributed across host organizations
3. Smart contract - secured program implements a contract between parties to validate, write transactions on the ledger with event support
4. Consensus  method- policies define how transactions are approved, posted to the ledger
5. Governance services to manage the network

smart contracts & transaction flow

existing

Which existing contracts are candidates for smart contracts?

https://www.globaltrademag.com/how-to-save-time-and-money-with-blockchain-smart-contracts/

1. Use factur3.io on the existing contractual relationships
2. are there trust issues, costs, risks in the relationships?  true with external contracts vs internal
3. are there contracts difficult to execute between parties ( vs simple ones that run well all the time )?
4. is there extensive paper documentation required with signatures ?
5. are there counter party risks between companies on contract execution?
6. are there frequent reconciliations, rework, returns, losses, inspections, discounts that occur?
7. what data is currently used in the existing processes ?
8. should the data inputs be automated, improved?
9. what audits and compliance issues exist?

current network compared to blockchain network

> visual + issues – show ETL model – separate db view

Given defined transactions and agreed contracts, which is better? Why?

https://hyperledger-fabric.readthedocs.io/en/release-2.0/blockchain.html

Current Business Networks - Integration Challenges

Sample scenario looks at commercial paper life cycle

Each organization has separate database with security, maintenance issues

Intermediaries needed for validations to reduce counter party risks

Added delays, errors, rework, audits, costs, risks, inefficiencies, compliance issues

ebc view

> visual + impacts – show mult shared writes to shared db view

https://hyperledger-fabric.readthedocs.io/en/release-2.0/blockchain.html

Blockchain Business Network - Coordination Benefits

Trusted, shared, historical, single version of the truth for all

Client apps call smart contracts to write to the ledger

Smart contracts write approved, signed transactions to shared, immutable ledger

Fewer delays, errors, rework, audits, costs, risks, inefficiencies, compliance issues

Coordination creates a Value Chain Network ( VCN )

Faster transactions and data

Better quality data with defined smart contracts for transactions, data validations

Trust in network participants with reputations

Reduced friction with known members, defined roles, rules for counter-party risk, governance

Highlights large companies using blockchain solutions
Key impacts: speed business processes, increase transparency, lower costs, improve compliance on value chain networks
Great place to understand blockchain value delivered
I made assumptions on which blockchain platforms they focused on

Compare Key Enterprise Platforms: Fabric,  Ethereum  Corda

Platforms

open-source

permissioned

private data

consensus

tokens

performance

Hyperledger - an Open Blockchain Solution provider

are you joining an existing network?

No need for Hyperledger

do you need to build a ledger or a network?

Hyperledger is a great starting point

Platforms vs Support Services

Focus only on Fabric today

Fabric Features and Impacts

features

A different type of distributed ledger
Users have digital identities to access
Transactions are signed by users
Endorsed transactions
Transactions hashed in sequence in blocks
Transactions are “write-only”
Smart contracts create transactions
Can integrate with payments, tokens
Public or private?
Permissioned or permissionless?
Options for private data
Event support

Impacts

Shared real-time data across organizations
Trusted, secured identity for users
Proof who created a transaction
Proof transactions are approved
Proof transactions occurred at a set time
Proof that transactions are not changed
Authorized access only, no direct data access
Enables payments, incentives for users
Who can read a blockchain
Who can write to a blockchain
Who can read shared, private transactions
Automated workflows with transaction finality

fabric networks

– logical vs physical nets w integrated svcs, data?

existing 

Blockchain networks with only a few organizations

Every organization may be a host on the network and the network can perform well

Blockchain networks with many organizations

A logical blockchain network may be created with

A few large host organizations running the physical network of nodes

Many participant organizations that join the network but do not host it and do not exist as nodes

An example would be OEM auto manfacturers and car dealers. A few large OEMs and many thousands of small car dealers.

OEMs might host nodes on the network

Dealers join as members but don’t host

Can Enterprise Blockchain add value to your BVN ?

<< adapted from the question list is ebc right for you – fab concepts flows >>

Is a shared, persistent data store useful? Maybe

Is there a need for shared data and data privacy? Maybe

Is improving trust and transparency in our business network a goal? Maybe

Is a complete, accurate historical record of all changes useful? Maybe

Is tracking consent, agreement and signatures important? Maybe

Is reducing friction, risk and settlement times important? Maybe

Are the transactions supporting business contracts? Probably

Are compliance and audit important? Probably

Do multiple parties need to add data or process transactions? Probably

If half of these factors apply to your use case, blockchain may add a lot of value

Potential Value Points

re-think BVN outside your organization

who are then end customers?
