Smart contract != block chain != crypto currency

Bitcoin may be a hype; the underlying technology, known as Blockchain, could disrupt many industries. As long as you are dealing with transactional data, Blockchain can help.

Blockchain is a decentralized ledger system, which would provide secure and permanent records.

Blockchain's Promises

  • no downtime, no error or lost records. On traditional server architectures, if a single app is compromised or goes offline, many users and other apps are affected.
  • no censorship, transparent, safe, auditable, no fraud: multi-source identification
  • no third-party interference. By tokenizing the process and eliminating any middlemen
