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. By allowing digital information to be distributed but not copied, blockchain technology created the backbone of a new type of internet. Virtually anything of value can be tracked and traded on a blockchain network.
