Introduktion


Näringspolitiskt forumBlockchain – Decentralized Trust

oktober 2016

Claudia Olsson m fl


”Genom blockkedjan kan handel, kommunikation, ingående av kontrakt

och permanent registrering av information på sikt komma att göras i stor skala utan behov av anförtrodda

tredjeparter”

ur Blockchain – Decentralized truth

Näringspolitiskt forum oktober 2016


”Blockkedjan ärglobal, digital, okorrumperbar

och behandlar varje användare lika”




”Eftersom blockkedjan tar bort behovet av tillit mellan parter kapas

behovet av mellanhänder”

”The digital disruptors” – a digital layer between providers and users


”Vi vet inte vart denna teknik kommer att föra oss men det är hög tid att

diskutera ochutforska

dess utmaningar och möjligheter”

• Digitaliseringen har slagit igenom på bred front.• Vi närmar oss ett läge där den finansiella sektorn och

bankerna står inför ett skifte

• Blockchainbaserade lösningar ‐ gör marknader mer transparanta ‐ minskar osäkerheten om finansiella risker

Bakgrund och konsekvenser


Historik och Teknik


• Block = ett antal transaktioner• Blockchain = en lista med block där varje block pekar på

föregående block• Varje block krypteras ihop med kopplingen till

föregående block− Ett försök att manipulera en tidigare transaktion leder till att

kedjan bryts då krypteringsalgoritmerna inte stämmer längre• Konsensus

− Många noder måste tillsammans godkänna en transaktion• Distribuerad lagring

− Alla noder har en egen kopia av alla transaktioner• Ingen central hantering = peer‐to‐peer

Tekniken – utgångspunkt


• Satoshi Nakamoto 2008https://bitcoin.org/bitcoin.pdf

• The first implementation of a blockchain• Bitcoin is a crypto currency, traded as BTC• With a bitcoin wallet you can own your own bitcoins• Transferring bitcoins from one wallet to another takes

minutes regardless of where in the world the owners of those wallets are

• “Permissionless”

Bitcoin


• Ethereum was concieved in 2013 by Vitalik Buterin, a Canadian of Russian descent.

• He created Ethereum as an open source project whenhe realized that developers needed a more flexible platform than the bitcoin blockchain provided

• Ethereum is a platform that runs decentralizedapplications, namely ”smart contracts”.

• The currency of Ethereum is called ether• Second biggest blockchain after Bitcoin

Ethereum


Några case


• Abra (www.goabra.com)− Bitcoin‐based remittance service− With Abra you can send and receive money without a bank

account, across the world, in local currencies− Human ATM’s

• Circle Pay− Send £, €, $ without fees− Built on top of Bitcoin

Money and payments


• R3 is a consortium of more than 70 of the world biggestfinancial institutions.

• More than 70 companies (mainly banks) contribute to R3− SEB, Nordea, Danske Bank, HSBC, Goldman Sachs, J.P. Morgan,

Deutsche Bank, Wells Fargo, Bank of America

• The consortium's joint efforts have created an open‐source distributed ledger platform called Corda

R3 Company – background


• “Corda is a distributed ledger platform designed and built from the ground up for the recording and automation of legal agreements between identifiable parties. It is heavily influenced by the requirements of the financial industry”

• ”uses the same technology as bitcoin but restrictsaccess to transaction data”

• Uses the term ”distributed ledger” in theircommunication, not blockchain

• The Corda platform was made available as open source in November 2016

R3 Corda platform


• Everledger is a permanent ledger for diamond certification and related transaction history

• Verification for insurance companies, owners, claimants and law enforcement

• Every diamond is scanned to create a unique ID. This ID is attached to the smallest possible bitcoin value (satoshi), which makes it possible to trace all transactions with this diamond

(100,000,000 satoshi = 1 bitcoin)

Everledger

Blockchain Revolution

Don Tapscott


• ”What a spectacular book!It makes me think we´re at one of those times in technological, economic, and social history where the sky is the limit.”

‐ Steve Wozniak, cofounder, Apple Computer

• ”Don and Alex brilliantly illuminate the technology thatcould profoundly impact the way we manage issues oftrust, security, and privacy for years to come”

‐ Indra Nooyi, chairman and CEO,PepsiCo

Blockchain Revolution – Back page reviews


• today trust in business and other institutions is mostlyat an all‐time low

• Internet lacks the much‐needed security• ”digital conglomerates” like Amazon, Google, Apple and

Facebook are capturing the treasure troves of data

• The blockchain technology have a trustworthy global platform.

• There are no central database to hack• We are calling it

”the Trust Protocol”

In search of the trust protocol


With blockchain technology a world of new possibilitieshas opened

We can; ‐ protect our privacy‐ monetize our own information‐ ensure that creators are compencated for theirintellectual property

‐ start to change the way wealth is distributed

”The sky seems to be the limit”

The Trust Protocol


1. Transportation

2. Infrastructure Management

3. Energy Waste, and Water Management

4. Resource Extraction and Farming

5. Environmental Monitoring and Emergency Service

6. Health Care

7. Financial Services and Insurance

8. Document and other Record Keeping

9. Building and Property Management

10. Industrial Operations – The Factory of Things

11. Home Management

12. Retail Operations and Sales

Twelve disruptions


• Reduced costs (elimination of expensive intermediaries)

• Increased Revenue (freeing up excess capacity for reuse)

• Speed (end‐to‐end automation)

• Improved effectiveness (reduce human errors)

• Increased security and integrity

• Increased privacy protection

The Economic Payoff


• A blockchain governance network is critical to stewardship of this global resource.

• We need all stakeholders globally to collaborate and provide leadership in the same way as Internet is governed, where no government, country or corporation controls the internet. It works.

A new agenda for the next digital age


Harvard Business ReviewThe truth about Blockchain

Marco Iansiti and Karim R. LakhaniJanuary‐February 2017

eliminate intermediariesand

that could transform the economy”
