- 8. www.vestforsk.no Open vs. closed blockchains Open (permissionless) Closed (permissioned) Who can update Everybody with enough resources Selected people/org. Who prod. data Everybody participat. Customers of org. Incentive to follow rules Direct economic (carrot & stick) Reputation Storing Distributed Centralized Trust in central actors No Yes Transaction costs - + Speed (trans./sec.) - + Immutability + - Currency/»token» Yes No Example Bitcoin, Ethereum HyperLedger
- 9. www.vestforsk.no What is genuine with (open) blockchains? Immutability «tamper proof» vs. «tamper evident» .. but not in itself (ref. Ethereum and The DAO) Censor-ship resistant «unwanted» transactions will also be processed as long as they follow the consensus rules Open for all and at the same time protect privacy
- 10. www.vestforsk.no What public sector needs to think through Interoperability open vs. closed blockchains Platform/infrastructure for public sector from «common components» to common platform Clear parallells to the growth of Internet in the 1980s/1990s
- 11. www.vestforsk.no Bitcoin as a platform and information infrastructure Bitcoin infrastructure (Network Services) Blockchain, Consensus, Ordering, Hash storage, Security Bitcoin currency Colored coins (Mastercoin, Counterparty ++) Sidechains Payment channels (Lightning Network..) Smart contracts
- 12. www.vestforsk.no Bitcoin and blockchain in public sector Authentication of documents badges, course certificates, CVs other certificates and licenses ++ Proof of ownership property +++ Economy transparency audit Think of Bitcoin/blockchain as a new Internet-based platform!
- 13. www.vestforsk.no Examples on the use of Bitcoin/blockchain Authentication of documents Course certificates from the University of Nicosia (digital currencies) MIT’s Blockcert is a suite for streamlining the work with certificates and CVs on the Bitcoin blockchain Proof of ownership Sweden and many other countries are experimenting with property registration on a blockchain What about Norway? Security and anti-spam machine-to-machine payments (as a safeguard against email spam, DDOS attacks, new business models for media companies ++) Internet of Things (IoT) is difficult, or impossible, to scale without a decentralized architecture. Blockchain tech. seems perfect.
