Blockchain technology is being talked about as one of the next big innovations to take hold across multiple industries. Businesses who focus on transactions, contracts, and assets management are just a few of the initial sectors of the economy which will be disrupted. As the underlying technology begins to take hold, time-consuming and labor-intensive functions will be replaced by automated and “always on” smart processes. Centralized models of trust and authenticity will be replaced by decentralized services and crowd-based consensus algorithms.

There will not be one blockchain but millions each build on an application-specific architectures. Any store of information that requires exchange or validation across indirectly related entities will reside on a blockchain. Blockchains are safe, secure, and immutable — but all blockchains are not created equal. We will explore the subject by examining several current generations of blockchain implementations.

Topics during this session include:

  • Architecture, Protocols, Algorithms
  • Distributed Ledgers, Smart Contracts
  • Trust / Consensus Systems
  • Decentralization, Virtual Computing Environment
