4 01 Wat is blockchain?

5 Defining Blockchain projects CRYPTOGRAPHY PEER TO PEER NETWORK CONSENSUS MECHANISM OPEN SOURCE CODE DECENTRALIZED LEDGER Private & Public Keys Hash Algorithms Merkle Tree Decentralized & distributed network architecture No central governing body Nodes linked over the Internet Nodes collaborate to validate information Use various types of consensus models Initial Bitcoin Blockchain uses Proof of Work Source code open to review by anybody Catalyst for wave of innovation Many different implementations today Public record of all transactions Every stakeholder has the same ledger Avoids cheating and automatically reconciles all data Value transfer via the internet without a trusted third party..validated by nodes within a network based on open source protocol completely transparently 5

8 Bitcoin blockchain the good news Distributed All network participants have a full copy of the ledger for full transparency Programmable A blockchain is programmable ( Smart Contracts ) Anonymous The identity of participants is (supposed to be) either pseudonymous or anonymous Secure All records are individually encrypted BLOCKCHAIN Time-stamped Transaction timestamp is recorded in a block Immutable Any validated records are irreversible and cannot be changed Unanimous All network participants agree to the validity of each of the records 8

9 Bitcoin blockchain the bad news Performance Bitcoin Blockchain is not able to support non-btc industry use-case throughput or latency requirements Technology Innovation Proof of Work consensus many not survive innovations in technology (e.g. Quantum) Privacy The identity of BTC Blockchain participants can be, and has been, reverse engineered Real Costs for Use Minting new currency as Proof of Work mining rewards disguises true costs of using BTC Blockchain. Costs are hidden, not removed, and every party has to come to an end one day. BLOCKCHAIN Legacy Debt & Compliance A huge amount has been invested in current systems and no regulator will sanction BTC Blockchain for industry usecases Security Although the basic BTC Blockchain protocol has proven very secure, private key management in wallets and exchanges has led to problems (Mt. Gox, Bitfinex) Governance The Bitcoin community cannot even decide how to best resolve the problems on this slide 9

11 Blockchain is an inspiration to rethink our world Basic questions raised by emergence of blockchain technology Why do organisations have so many replicated functions within their value chain? Why are organisations competing on IT infrastructure? Can we digitize assets and identities across value chains? Can we create programmable money and program compliance into this money? Can trust be organised at transaction level rather via a trusted third party? Can we automate accounting through smart contracts and triple entry accounting? 11

13 Inspirational blockchain use cases The essence of blockchain is making identities, assets and relating properties truly digital across the value chain. When this is realized reconciliations between different databases are no longer needed and the concept of automating processes and products through smart contracts becomes a possibility. Below a list of some inspirational blockchain use cases Identities Assets Currency Applications 13
