Download as PPTX, PDF1 like484 views
The document discusses the application of blockchain technology in educational management, emphasizing its potential to secure, verify, and manage credentials without intermediaries. It highlights the decentralization, transparency, and immutability of blockchain, which can prevent issues related to centralized databases, such as unauthorized changes and access restrictions. Additionally, it outlines the use of smart contracts and the distinction between open and closed blockchains, advocating for open blockchains to maximize social value.
Beyond the hype, a blockchain approach to educational management
- 1. A BLOCKCHAIN APPROACH TO EDUCATIONAL MANAGEMENT BEYOND THE HYPE Anthony F. Camilleri #EDEN 18 Annual Conference, Genoa, 19th June 2018
- 3. Blockchain is a digital way for people to transfer assets directly between each other without an intermediary
- 4. BLOCKCHAIN IS THE TECHNOLOGY BEHIND BITCOIN
- 6. Central Database STRUCTURE OF A MODERN DATABASE Users store their information Institution manages & controls Parties consult database
- 9. A CENTRALISED LEDGER OPERATOR COULD •the rules for recognition of credentialsChange •access to the database to institutions or individualsRestrict •parts of the databaseDelete •the database in an unauthorised mannerMisuse •credentials by changing database entriesRevalue
- 10. BLOCKCHAIN SOLVES THESE PROBLEMS BY REMOVING THE INTERMEDIARY Each user (node) stores a complete copy of the database Each user (node) has to approve each entry The version with the most copies is the ‘true’ version
- 11. DECENTRALISED
- 12. TRANSPARENT
- 13. IMMUTABLE
- 14. THREE THINGS YOU CAN STORE IN A LEDGER ASSET TRANSACTIONS 01 NOTARIZED CERTIFICATES 02 SMART CONTRACTS 03
- 20. HASH FUNCTIONS PROVIDE UNIQUE IDS FOR ANY DIGITAL DOCUMENT
- 21. NOTARIZATION ON THE BLOCKCHAIN MEANS STORING ITS HASH ON THE LEDGER THIS ALLOWS YOU TO CERTIFY TRUTH AT A POINT IN TIME
- 22. NOTARIZATION ON THE BLOCKCHAIN MEANS STORING ITS HASH ON THE LEDGER THIS ALLOWS YOU TO CERTIFY TRUTH AT A POINT IN TIME
- 23. AUTOMATICALLY VERIFIABLE SECURE CREDENTIALS Any institution can issue a digital credential (in any format) to a learner and register the hash of that credential on a blockchain The learner can hold the credential themselves on their own device or in an online wallet Any person wishing to check the authenticity can simply compare the hash of the document against the entry on the chain.
- 24. AUTOMATICALLY VERIFIABLE SECURE CREDENTIALS tamper-proof revocable user-held independently-verifiable
- 25. APPLICATIONS
- 27. POTENTIAL TO DISRUPT Issue and recognition of credentials Tracking of Research Impact Research Lifecycle Management Prevention of Diploma Mills
- 28. SMART CONTRACTS
- 29. SMART CONTRACTS STORE CODE ON THE CHAIN
- 31. IN A SMART-CONTRACT Contracts may require votes to take effect – voting is technologically incorruptible Voting is linked to an action – not a proposal for an action Once a contract gets the required votes it automatically executes Contracts can be changed, but only in relation to the votes received Everyone has full visibility into each step
- 36. IN THE LONG-TERM, BLOCKCHAIN HAS THE POTENTIAL TO DISRUPT THE GOVERNANCE AND EXECUTION OF EVERY SINGLE PROCESS CONTROLLED BY A DATABASE
- 37. OPEN VS CLOSED BLOCKCHAINS Open Chains • decentralized governance • data portability • independent verification • direct access to wallets • open standards Closed Chains • centralised governance • data silos • Verification through intermediaries • Mediated access to wallets • Proprietary closed standards
- 38. ONLY OPEN BLOCKCHAINS BRING CLEAR SOCIAL VALUE
- 39. BLOCKCHAIN IS STILL EMERGING TECH
- 41. FROM A FAUSTIAN BARGAIN more convenience more connectivity less privacy less ownership
- 42. TOWARDS A MORE IDEALISTIC WORLD more convenience more connectivity less privacy less ownership
- 43. THANK YOU FOR YOUR ATTENTION ANTHONY F. CAMILLERI ANTHONY@CAMILLERI.COM
