10. What is a Blockchain?
• Database
• Records Cryptographically Linked
• Redundant Copies Replicated among Stewards /
Nodes
• Consensus Protocol – Who gets to write a new
record
• Ability to execute automated processes using
Smart Contracts
• Can interoperate with Digital Currency

13. Bruce Schneier Comments on Trust
2018 Hyperledger Conference
“Blockchain shifts trust in people and institutions to
trust in technology”
14. Bruce Schneier Comments on Trust
February 2019 Blog
(https://www.schneier.com/blog/archives/2019/02/blockchain_and_.html)
• What blockchain does is shift some of the trust in people and
institutions to trust in technology. You need to trust the
cryptography, the protocols, the software, the computers and the
network. And you need to trust them absolutely, because they're
often single points of failure.
• Blockchain doesn't eliminate the need to trust human institutions.
There will always be a big gap that can't be addressed by
technology alone. People still need to be in charge, and there is
always a need for governance outside the system.
15. Novel Uses for Blockchains
• Provenance
• Diamonds
• Title
• Assets
• Supply Chain
• Stored Value
• Cryptographic Token
• Stored Value – Mileage Points, Timeshare Exchange
• Transaction Record
• Financial Exchange
• Books of Record
• Self Sovereign Identity
• Verifiable Credentials
