The Decentralized

Web Platform

A new evolution of the Web that enables decentralized apps and protocols.

Web5:

Evolving the Web

Today

The Web We Want

In the current Web model, people are users who do not own their data or identity. They are given accounts by companies and their data is held captive in app silos.

To create a new class of decentralized apps and protocols (e.g. tbDEX) that put individuals at the center, we must empower them with self-owned identity and restore control over their data.

Personal and social communications

Financial interactions

All the apps we love

Apps built for Web5 store their data with you

3

The Decentralized Web Platform (DWP) enables developers to write Decentralized Web Apps (DWAs) using Decentralized Identifiers (DIDs) and Decentralized Web Nodes (DWNs), returning ownership and control over identity and data to individuals <-- We are calling this Web5

The Pillars of Web5

Self-owned identifiers that enable decentralized identity authentication and routing.

Data storage and message relay nodes that serve as the foundation for decentralized apps and protocols.

Data formats and models for cryptographic presentation and verification of claims.

Decentralized Identifiers

Verifiable Credentials

Decentralized Web Nodes

Decentralized Identifiers (DIDs)

5

Identifiers are self-generated and self-owned

No centralized providers or trusted authorities

No special utility tokens or subjective consensus

Highly resistant to all forms of interdiction

IDs can be made universally discoverable

Alice self-generates her DIDs and anchors PKI (key and endpoint) state changes in the network.

Bob can discover all DIDs indexed in the network to independently resolve and verify them.

Decentralized Web Nodes

7

Send and receive messages over a DID-encrypted universal network

Designed to support individuals, companies, machines, or any other entity

Crawlable DID-relative addressing of data

Masterless eventually consistent replication of instances across devices and clouds

Data can be optionally encrypted with an individual's DID keys

Discover any form of published data simply by knowing its semantic type

Replicated

Secure

Semantic Discovery

Async Message Threads

Supports any identity type

Universally Addressable

Decentralized Web Nodes (DWN, DWeb Nodes) is an emerging standard for data storage and relay that enables entities of any type (people, organizations, etc.) to send and store encrypted or public messages and data, enabling a wide variety of decentralized apps and protocols to be built on top.

Features

The Anatomy of an Identity Wallet

8

DID Functions

Support create, update, and recovery of DIDs across all supported DID Methods

Data Management

Provide UI and functionality to manage credentials and app data stored in DWNs

DID Auth

Perform authentication and manage authorizations (e.g. DWN authz capabilities)

Context Management

Maintain and enforce which DIDs are used with different people, apps, and services

Credential Functions

Sign, verify, discover, and present credentials to verifying parties

The combination of Decentralized Identifiers and Decentralized Web Nodes produces a Web of DID-secured messaging, data sharing, and credential exchange that can replace one-off protocols (encrypted messaging, photo sharing, etc.) with universal standards for all types of semantic data exchange.

When viewed from 10,000 feet, tbDEX is a DWN-based threaded messaging and data exchange protocol layer that runs atop the substrate of DIDs and Decentralized Web Nodes.

PFI 1

Alice’s tbDEX-aware app knows the DIDs of various PFIs and sends them Ask messages to initiate an exchange.

navigator.did.send({ schema: “tbd.website/schemas/ask” })

Alice’s local DWN

PFIs respond to Alice’s Asks via Bid messages sent back to Alice’s DWeb Node.

It’s not fun to regurgitate your playlists over and over again for different music apps, so let’s stop doing that.

Alice’s remote DWN

TIDAL

Groove

Groove secures the ability to write schema.org/MusicPlaylist objects to Alice’s DWNs, and adds a new entry.

TIDAL, which previously secured the ability to read Alice’s schema.org/MusicPlaylist entries, can read the entry Groove added.

Your preferences, tickets, reservations, and other travel data are strewn across 100s of different hotel, airline, and travel apps in a massive, unworkable mess. DIDs + Decentralized Web Nodes can help unify these flows and experiences.

Alice’s remote DWN

Alice grants her hotel, airline, and rental car provider the ability to add schema.org/Reservation objects to her collection of trip-related data.

Alice can grant any app she chooses access to reservations and tickets stored in her schema.org/Trip data to help her visualize her itinerary.
