The Web Beyond
Blockchain: greater than the sum
Cryptography - Ancient (in internet time)
P2P Networks - Sean Parker is 36 now, folks
- Consensus Algorithms - Meh, a new riff
Proof of ownership
Generate cryptographically secure transactions synced to a worldwide network that maintains a single, global ledger of the chronological state of ownership for all participants.
Blockchain *HUH*, what is it good for?
Absolutely these things:
What is identity?
A collection of attributes, activities, and interactions provably linked to an entity
The Brass tacks of identity
a Product-centric view
The identity opportunity blockchain presents is historic and unprecedented
Signed data backed by public private key cryptography
Global index of identifiers and their associated identity data
Blockchain transactions that register identifiers
An open, user-sovereign, global identity system will be integrated with almost every product, service, and human activity
The data that comprises those use-cases will not live on the blockchain. Instead, they will be enabled and anchored by blockchain identities
Jane's new car
Lucy, the saleswoman
Bill, the lender
Jane, the buyer
The dealership generates a data object for Jane's loan, signed by the saleswoman, Lucy, and the lender, Bill.
Jane agrees to the terms, so she uses her blockchain identity to sign the loan object.
The signed, cryptographically verifiable loan object can be produced by any of the parties involved to verify the contents and agreeing parties.
The result: a record that is secured by the blockchain, without requiring a transaction on the blockchain.
