[Reblog from the W3C Blog: Collaborating across W3C and Ecma for web-interoperable server runtimes through WinterTC]
WinterTC
WinterTC is an Ecma International Technical Committee aiming to provide a space for JS runtimes to collaborate on API interoperability.

Goodbye WinterCG, welcome WinterTC | Deno
WinterCG, the Web Interoperable Runtimes Community Group is moving to Ecma as TC55 to be able to publish standards.

Web publishing is facing its next challenge: a new iteration of centralizing platforms. BUT there is also a new wave of open protocols and standards that can help us gain our independence. Next month in NYC we are gathering a group of frontier technologists and popular web publishers to discuss how we can sail into this next platform shift as captains. #ProtocolsForPublishers Learn more and sign up here: https://pfp.unternet.co We will be hosting talks on #atproto #mcp #webapplets and web payments, and give publishers the opportunity to interact directly with developers working on these frontier technologies. Thank you to Unternet, Graze Social, Free our Feeds, and betaworks for their support.

Exploring interoperability & composability for local-first software | grjte
Check out the project at https://github.com/grjte/groundmist-syncCross-posted to https://baincapitalcrypto.com/atproto-for-local-first-interoperability/ This is the third exploration connecting local-first software with the AT Protocol (atproto). Previously, I explored how atproto can enable new fu...
Kicking off our alpha program
In March, we shipped a stable version of Web Applets, a protocol that extends the web to make it possible for agents and websites to communicate, with just a few lines of JavaScript.

Decentralization Trade Offs in AT Protocol and ActivityPub DWeb Camp 2026
Christine Lemmer Webber is lead author and co-editor of the W3C ActivityPub specification. Daniel Holmgren is Head of Protocol at Bluesky, working on the AT Protocol specification at the IETF. Join us for a discussion on decentralization trade-offs and other design decisions in the two protocols, and what that means for different architectures, structures, and even future points of convergence. Moderated by Boris Mann
WebID - W3C Wiki
The W3C is still exploring better ways to do authentication, for example in the 2014 workshop on authentication. The WebID is a Community Group, and anyone can start a Community Group. A Community Group does not necessarily reflect the endorsement of the W3C, but we encourage grassroots communities to experiment with technology that may become a future standard.

Protocols for Publishers
pfp.unternet.coI want organizers to be as excited as I am about the phase shift happening on the web right now. If we nerds can help the organizers see what we're seeing, which is the potential for a systemic overhaul of the web as we know it, the organizers will understand what they can ask us to build for them.
