Web5 - Open to Build - Block-TBD

The document discusses plans for a new "Web5" initiative to create a decentralized web that puts individuals in control of their identity and data. The summary is: 1) Web5 aims to create a decentralized web where individuals own their identity and data through technologies like decentralized identifiers (DIDs) and verifiable credentials, rather than relying on centralized platforms. 2) It will use decentralized web nodes to store individuals' data across devices and networks, allowing them to grant access and share information more privately and securely. 3) The initiative aims to launch basic consumer tools by mid-2023 and have a fully-featured platform by late 2023/early 2024 to restore individual control over digital identity and data

- 3. Back to the Future of the Web
- 4. ● 16 years ago, browser vendors published the first draft of the HTML5 spec. ● HTML5 introduced powerful new features to the Web that went far beyond HTML (e.g. APIs for geolocation, audio, local storage of data). ● HTML5 enabled websites to deliver better experiences, but since then centralization of the Web become a serious problem. A little Web history We need a new effort to make the Web what it was always supposed to be
- 5. 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 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 We need a better Web
- 6. The Web was created without a means for individuals to own their identity. Web5 fixes this with Decentralized Identifiers. The Web lacks a way for individuals and businesses to convey trust and reputation. Web5 fixes this with Verifiable Credentials. The Web’s app model is based on storing data with centralized corporate silos. Web5 fixes this with DWeb Node personal datastores. Getting to a better Web did://
- 7. What’s in the box?!?
- 8. Decentralized Identifiers (DIDs) • Owned and controlled by individuals • No reliance on trusted authorities • No special tokens or crypto schemes • Strongly resistant to interdiction • Discoverable and universally resolvable Bob is able to independently lookup and verify the keys and endpoints of Alice’s DID. Alice self-generates her DIDs and anchors their keys and endpoints in the DID network. Web5.resolve(did:of:alice) did:of:alice = { keys: {…}, endpoints: {…} }
- 9. Verifiable Credentials (VCs) Issuer Verifier iss: did:example:school sub: did:example:alice claims: degree: Economics name: Alice Smith + issuer’s digital signature iss: did:example:school sub: did:example:alice claims: degree: Economics name: Alice Smith + issuer’s digital signature + subject’s digital signature Anchor Issuer’s DID with attached public keys and endpoints id: did:example:school keys: { JWK } Presentation of Educational Credential Issuance of an Educational Credential Alice’s Wallet Resolve Issuer’s DID and verify credential with attached keys
- 10. Decentralized Web Nodes (DWNs) DID-relative addressing of data the owner publishes. Masterless eventually consistent replication across devices and clouds. Data can be optionally encrypted with the DID keys of the owner. Replicated Encrypted Supports Any App Type Store large files, such as images, audio, video, etc. Large Binary Support

A more powerful, more personal Web Alice’s addressable DWeb Node Everyone Alice allows gains instant awareness of changes to the data she has shared with them. 2 Alice updates her new address and other personal details in her DWeb Nodes when she moves. 1 Friends, family, contacts Businesses & Employers Institutions & Organizations
- 14. Hotel me your travel plans Alice’s DWN Alice grants her hotel, airline, and rental car provider the ability to add reservations, tickets, and receipts to her collection of trip-related data. Alice can give any app, service, or individual she chooses access to reservations, tickets, and receipts from her travel data. 1 2 DWN.records.write({ schema: “schema.org/Reservation” data: { … } }) Hotel Car Rental Airline Travel App DWN.records.read({ schema: “schema.org/Trip” data: { … } })

- 17. DWeb Node Server Web5 SDK • Runs in browser, Node, Electron, and other common JS runtimes • Connect to apps with DIDs • Includes a local DWeb Node • Install app protocols and interact with data in DWeb Nodes • Runs in Node 18+ • Multi-tenant, so one instance can handle the data for many DIDs • Persists files to disk via Level, but any database can be used Available now in Tech Preview Available now in Tech Preview
