AI@Work: Blockchain EDU
Blockchain is a narrow version of DTL, Distributed Ledger Technology. A blockchain is a chronological record of transactions, recorded and cryptographically linked to the previous record, forming a chain. Three key characteristics of blockchain are integrity, transparency and democracy. This was first created to serve the financial industry. Distributed Ledger Technologies and blockchain are now disrupting industry after industry and igniting innovation.
These technologies have sparked praise, criticism, wonder, investment and fast-moving revolutions. The education community is scurrying to leverage blockchain technologies. They can address the issues of data sharing and transparency in schools, companies and institutions. Blockchain combined with AI is very powerful.
Integrity refers to the fact that records in the blockchain are cryptographically linked and are nearly impossible to alter. This helps to ensure the integrity of the data and opens up opportunities for new ways of storing and sharing digital credentials. Identity protocols combined with other technologies can provide transparency, utility and trust. These unique identity conventions benefit risk management and impact privacy. Blockchain is an exciting new technology that coupled with AI is just beginning to be explored.
Blockchain has the potential to add validity and security to student data for assessment and credentialing. It is an append-only architecture. It is impossible to reverse a transaction on a blockchain.
Transparency is foundational to blockchain. It is based on the knowledge of two facts: who owns the asset and who participated in forming the contract. It has this ability because of a distributed infrastructure. Blockchain might provide a connection between formal learning, non-formal learning and informal learning processes. Blockchain databases are secure, distributed and accessible. They provide the learner with more autonomy in monitoring their own learning strategies. They can help learners optimize their time. They may have the ability to create their own ecosystem of interactions and relationships. The 21st century has different needs for learning and must support new pathways. Blockchain has the flexibility to provide the learner with opportunities to create their own environment of interactions and relationships. It can support lifelong constructivist and collectivist environments.
