Todo list: https://trello.com/b/8qUutkmP/identifi
What
- Concept: https://medium.com/@mmalmi/learning-to-trust-strangers-167b652a654f
- Global address book
- Anyone can edit and verify contact details
- Users can give each other eBay-style reviews and trust ratings
- Filter all information by its author's position in your web of trust
- For example, only show the content created by your friends and the people they trust
- Decentralized - data is stored and indexed on the devices of its users (on IPFS). Compares to a phone's address book or a local DNS cache.
- API for integration with various trust or identity dependent applications
Why
- Keep your contact details, payment addresses etc. up-to-date and verified
- Makes it possible to trust people you have never met
- Utilize your good reputation in various services and situations
- Reduces risk of trade or loan, thus reducing cost
- Prevent spam (by accepting messages only from trusted / socially connected senders)
- Prevent fake accounts used for commercial or propaganda purposes
- Provide identity verifications to people who lack official ID
- Facilitate gift economy / time banking
- Distributed public messaging, with trust lists instead of centralized moderator power
- Censorship-resistance
- Open database, vs. proprietary information silos of reputation and online identity
- No monopoly on credit ratings
- Ubiquitous reputation as non-violent, cost-effective and decentralized justice
- Everyone can choose whose judgement or review to trust
- Incentive against antisocial behavior
- Incentive to restore trust by compensation and apology for misdeeds
How
- Identifi message: [author identifiers, recipient identifiers, message][signatures]
- Identified by content hash
- Signed by the entity which verified that the message originates from the named author. Thus, all end users need not to have a crypto key of their own.
- Encoded and signed as JSON Web Tokens
- Messages are stored and indexed locally in an SQL database
- Nodes maintain their own trust indexes which are updated as new messages arrive
- Message storage priority is based on its author's and signer's position in the node's web of trust
- Messages and indexes are also globally stored on IPFS
- Can be used in serverless mode
- btree indexes
- Crawl initial data from existing social networks and review systems
Possible applications
- Facial recognition and identifi-cation with a AR glasses
- Thumbs up to the friendly bus driver, policeman or the stranger who helped you
- Mywot.com-style browser plugin for website reviews
- Bitcoin UIs, connect addresses to identities or vice versa
- Email plugin
- Generate trusted senders list from email history
- Require new senders to be on identifi - send automatic response if not
- Decentralized marketplaces, P2P trade and finance
- Check escrow or trader reputation
- Airbnb, eBay, Uber, LocalBitcoins etc.
- Time banking, gift economy
- Uncensored and sockpuppet-resistant reviews and recommendations for products, restaurants etc.
- Public messaging, automatically show or hide authors
- Social network based routing protocols
- Decentralized alternative to DNS - let your WoT decide which IP a name maps to
