Blockchain - have we missed the boat? by Raivo Ruusalepp - EuropeanaTech Conference 2018

  1. 1. Blockchain - have we missed the boat? Raivo Ruusalepp National Library of Estonia 16.05.2018 www.nlib.ee
  2. 2. Every new technology is a form of utopia 2
  3. 3. A what? Blockchain is a type of distributed ledger technology in which validated sets of transaction records are grouped into blocks, which are then chained together cryptographically, computationally validated and broadcast throughout a peer- to-peer mesh network. Arvind Narayanan, Joseph Bonneau, Edward Felton, Andrew Miller, Steven Goldfede, Bitcoin and Cryptocurrency Technologies, Princeton University Press, 2016 Blockchain relies on established cryptographic techniques to allow each participant in a network to interact (e.g. store, exchange, and view information), without preexisting trust between the parties. 3
  4. 4. What? 4 Forrester Research
  5. 5. What? 5 Computerworld (2018) Distributed ledger technology
  6. 6. Which flavour? • Bitcoin – www.bitcoin.org • Ethereum – www.ethereum.org • Public • Commercial • Private 6
  7. 7. What for? Cut out the middle man • FinTech – cryptocurrencies, money transfer, securities trading, crowdfunding Smart contracts • e-Health – Patient records (e.g. Estonia) • Recordkeeping – e-Notaries – Land registries (e.g., Georgia, Sweden, Honduras) Trust tracking • Intellectual property rights tracing (e.g. Mycelia, Ujomusic) Encryption services • Data security 7

  10. 10. Blockchain and cultural heritage Cryptocurrency based solutions: • Cultural Places - cultural user journey combining location based information, ticketing, crowdfunding, map & routing and trip planning (https://www.culturalplaces.com/) • ICOs for: – Archaeological finds (Kapu coin), IPR (Creative Chain’s Crea; WhoLoDance), digital preservation (Witcoin) 10
  11. 11. Lessons learned • Not necessarily a better technology to replace our existing solutions: – Scalability issues • Cost of writing a block is fluctuating – Technology issues • Speed of writing a block can be slow – Organisational issues • Risks of the distributed model have not been fully explored yet • Need to start from the business case before selecting blockchain type 11
  12. 12. Opportunities • Blockchain technology is maturing and has begun to deliver business benefits • Cultural heritage community needs to get engaged and start playing with this technology now – Contribute and influence the direction where the platforms are going • This needs to be a collaborative effort since a single institution has little to benefit from it – Tracing provenance – Authenticity – Identification • We have not missed the boat. Yet! 12
