BLOCKCHAIN EXPLAINED

. . WEALTH & MARKETSBUSINESS NETWORKS . .

Business Networks need connectivity

• Between customers, suppliers, banks, partners

• Operate cross geography & regulatory boundaries

Wealth generated by flow of goods & services in transactions, according to contacts

Markets are core to process

• Public (fruit market, car auction • Private (supply chain, bonds)

TRANSFERRED ACROSS NETWORK TO BUILD VALUEASSETS

Two types:

• Tangible, e.g. a house

• Intangible, e.g. a mortgage

Intangible assets subdivide: • Financial, e.g. a bond

• Intellectual, e.g. a patent

• Digital, e.g. video

Cash is also an asset • property of anonymity

BUSINESS’ “BOOK OF RECORD”LEDGER

Ledger

• Updated on asset transfer in or out of business

• Multiple Ledgers

Transaction - asset transfer between ledgers • e.g. John gives Matt a car (simple)

Contract - condition for asset transfer

• If Matt pays John money, then car passes from John to Matt (simple)

• If car won't start (as decided by third party arbitrator) funds do not pass to John (more complex)

MEET BLOCKCHAIN

• Trusted, distributed ledger

• Shared business process

PROBLEM - DIGITISATION OF AGE OLD PROCESS

BLOCKCHAIN FOR BUSINESS

Privacy

Shared ledger

Smart contract

Trust

Append-only distributed system of

record, shared across the business

network

Appropriate visibility; transactions are

secure, authenticated &

verifiable

Business terms embedded in transaction database & executed with transactions

Transactions are endorsed by relevant participants

Differs from bitcoin in key areas: • Identity over anonymity • Selective endorsement over proof of work • Assets over cryptocurrency

BENEFITS

Saves TIME

• Near instantaneous transactions

Removes COST

• In overheads & intermediaries

Reduces RISK

• Tampering, fraud, cyber crime

Increases TRUST

• Shared processes & records

SELECTED USE CASES

Shared Reference Data

• Collaborators share critical information

• Tamper proof record of changes, control over who updates

Supply Chain

• Complete history of who’s owned what, and when

• Held in tamper proof records, control over who can change

Audit & Compliance

• Efficient way to inspect dispersed, trusted transactions

• Auditor is part of blockchain network with access to all

Letter of Credit

• Efficient way to implement supply chain financing

• Blockchain allows counterparts to validate transaction

NICHE

2009 (OR EARLIER) - 2014AGE 1 - NICHE

• Cryptography in hieroglyphs, 1900 BC

• 19th Century - becomes “scientific” - cryptanalysis • WW II - mechanical cypher machines

• Early 2000 - encryption through public key algorithms

• Bitcoin born in 2009, Wikileaks accepted in 2011 . .

A Brief History of Cryptography". Cypher Research Laboratories. 24 January 2006. Retrieved 18 September 2013. https://en.wikipedia.org/wiki/History_of_bitcoin

• “an innovative payment network and a new kind of money”

OR . . . • An unregulated shadow-currency • The first blockchain application • Resource intensive (for anonymity)

. . . IN RESEARCH DIVISIONIBM INCUBATES . . .

• 12 labs on 6 continents, 3,000 researchers

• Primary research & transition to mainstream

• Typical Projects

• Quantum computing

• Artificial Intelligence

• Neuromorphic computing

• Cryptographyhttp://research.ibm.com

TALK

2015AGE 2 - TALK

• Gradual realisation that blockchain IS NOT bitcoin • Broader industry applicability - “blockchain for

business” • Banks view as both threat & opportunity

• Part of FINTECH movement • Technical discussions (lashings of gobbledygook) • Hype around blockchain starts as potential clarifies

IBM . . TO EMERGING BUSINESS

• Evaluate potential - initially in Finance Industry • Investigate fabric (aka plumbing) alternatives • Explaining blockchain in business terms • Business demonstrations - what can blockchain

do? • Start customer discussions, offering “hands on”

REF

EXPERIMENT

2016 (- AND CONTINUES)

AGE 3 - EXPERIMENT

• Banks & financial institutions start to experiment

• Other industries see potential & follow • Cross industry consortia arise, disrupt • Crazy use cases “blockchain’s the answer, what’s the

question”

• Hype hits fever pitch - customer confusion on business value

. . . AND PREPARE FOR MAINSTREAMIBM SUPPORT EXPERIMENTS

• Key contributor to Linux Foundation project

• Engagement approach - making blockchain real

• Hyperledger Fabric code for customer use • Customer projects (80 in year) and references • Other industries embrace, find core use cases

USE

2017 (- AND WILL CONTINUE)

AGE 4 - USE

• Banks & financial institutions move to production • Other industries experimenting, planning to use • Value for business accepted, understanding lags

• Need for basic awareness continues • Still crazy use cases . . . • Hype fever pitch continues - maturity & applicability

Ten things blockchain is not:  http://bit.ly/BlockchainNOT

IBM - SCALE & GROW

• Contribution to Linux Foundation project continues

• Grow project capability - in delivery cells

• Usage in all industries, some more mature than others

• Continue with customer project & references

• Business network enablement (hard!)

• Digital education, certification - multiple channels

REF

. . . & BACK TO HYPE CYCLE THOUGHTS . .

• Gartner, hype cycle & blockchain [report, late 2016]

• Close to peak of inflated expectations, 5-10 years from plateaux

• Trough of Disillusionment

• Actions for success? (vendor, customer)

• Plateau of Productivity

• What will it look like? (vendor, customer)

PROJECT PITFALLS AND HOW TO AVOID THEM

KNOW YOUR BLOCKCHAIN FROM YOUR BITCOIN?

RISK

• Familiarity with bitcoin & non-permissioned ledger

• Not fully understanding permissioned blockchain for business

MITIGATION

• Educate

• Don’t jump over awareness steps

BLOCKCHAIN VALUE OR RELIGION?

RISK

• Hype confuses: blockchain is solution to all problems

• Project gets off to wrong start, then hard to correct

MITIGATION

• Test fit: Network | Consensus | Immutability | Provenance | Finality

• Test early, continue through project

SHARED CLARITY OF PURPOSE?

RISK

• Not all network members have same goals in mind

• Value for all members not clear or accepted

MITIGATION

• Joint workshop - use case - debate value until clear

• Business network members agree governance approach

REFS

DISCUSS COOPERATION, OR MAKE TRANSFORMATION?

RISK

• Easy for network members to discuss how they work together . .

• . . at expense of focusing on transformational opportunity

MITIGATION

• Don’t rush - allow time for discussion - careful facilitation

• Design Thinking: persona analysis, current methods, improvement opportunities

CONCLUSIONS

• Blockchain: trusted distributed ledger with shared business process

• Just entered USE phase - production

• Learn lessons from projects to improve
