The Fission project, now winding down active operations as of May 2024, utilized Decentralized Identifiers (DIDs) and User Controlled Authorization Networks (UCANs) to establish local-first identity and authentication protocols for web applications.

Key technical aspects of Fission DID include:

  • Identity Standard: DIDs were used to define "who you are," while UCANs defined "what you can do," allowing users to manage permissions without relying on external wallets or centralized backends.

  • Implementation: The webnative library stored DIDs locally, enabling the creation of keys from public keys and facilitating secure, peer-to-peer authentication and message signing via the browser's WebCrypto API.

  • Open Source Legacy: Although the company is closing, the underlying identity and data protocols, including the DID methods, remain open source and available on GitHub for continued community development.

AI-generated answer. Please verify critical facts.
Elaborate
How do UCANs differ from OAuth for identity? What is the Fission webnative library? How does Fission handle data persistence?

GitHub - nichoth/fission-did: What is UCAN?
https://webnative.fission.app/modules/ucan.html#build · The facts field gives a UCAN the ability to embed arbitrary data. The only purpose of this data is to be signed with the UCAN chain. This does the authentication of "a user that can do X, Y, and Z is signing this data". You can use it for really any signing purpose, including signing challenge text, hash preimages, associating URLs, and so on · In the tests it says 'session key fact' -- https://github.com/fission-suite/webnative/blob/ce2b50fb70a31db1081d8f1655f02b251164c826/tests/ucan/ucan.browser.test.ts#L64

Fission — Open Source Kubernetes-native Serverless Framework
Fission takes care of the rest: deployment, routing, scalability, availability. Use Kubernetes’ service discovery and networking to interoperate with other services, like Redis, Postgres, Etcd etc. Webhooks are a popular way to integrate with third-party services. Slack provides webhooks that are triggered by certain words or messages; GitHub provides webhooks triggered by events in Git repositories.

Farewell from Fission – Fission
We did a round of lay offs and focused on productizing our compute stack, powered by the IPVM protocol, as the Everywhere Computer. The team has shipped this as a working decentralized, content-addressable compute system in the past 6 months. Unfortunately, we have not been able to find further venture fundraising that is a match for us. The majority of Fission’s code is available under open source licenses.
