A Distributed Future: Blockchain and its Potential

Workshop co-presented by Columbia Blockchain Alliance and Blockchain at Columbia

An interactive workshop jointly presented by Columbia Blockchain Alliance and Blockchain at Columbia. The workshop will dive deep into the technology and actual use cases of Blockchain.

What is Block Chain?


  • Created out of a need to decentralize information
  • Announce ---> Show amount of transaction (block created) → crypt validators -→validators solves problem -→block is added to chain
  • Bitcoin (locked in supply of 21 million coins)
  • Mechanisms
    • Proof of Work - Bitcoin
    • Proof of Stake - involving user's stake of ownership
    • Proof of Authority
  • Blockchain is virtually unhackable currently
