Community Calls
WasmPay Demo: The Wasm Component Model for Cross-Language Payments
The April 2, 2025 wasmCloud community call streams live from the wasmCloud booth in the CNCF Project Pavilion at KubeCon + CloudNativeCon Europe 2025 in London. Brooks walks through the team's conference schedule — including talks on wasmCloud's road to the standards, SPIFFE workload identity, and WebAssembly on Kubernetes — and then demos WasmPay, a cross-language, cross-country payment processing platform. WasmPay shows the Wasm component model at work: banks supply transaction validators written in any language that compiles to WebAssembly, and wasmCloud composes each untrusted validator with a "platform harness" component that handles HTTP, NATS messaging, and the validation contract.
wasmCloud Q1 Roadmap, WASI Preview 3 & the Wasm Component Model
The March 26, 2025 wasmCloud community call is the last of the quarter, so Brooks Townsend walks the Q1 roadmap end to end — what shipped, what's in flight, and what slipped — with the Wasm component model and WASI Preview 3 dominating where maintainer time went. Open-source benchmarking Helm charts and a combined wash CLI/lib landed; a cron-job provider, logging-buffer error counts, and bundling are in progress; and a big chunk of the team's effort went upstream into Wasmtime and JCO to push WASI P3 across the line. The call closes with a look ahead to WASM I/O Barcelona and KubeCon + CloudNativeCon EU in London.
WebAssembly Composition & the Wasm Component Model in wasmCloud
The March 19, 2025 wasmCloud community call centers on the Wasm component model — both at build time and over the lattice. Brooks Townsend demos how to compose WebAssembly components with the wac plug tool, then shows new wash build functionality (in a PR) that performs the same composition automatically using WAC's Rust library, so developers never have to install or learn the CLI. The call then turns to a community proposal from LUK3ARK: "virtual components," a way for components to route invocations over wRPC to services that live outside the lattice — and the security questions that raises.
wadm Config Reconciliation, the Single wash CLI & KubeCon EU
The March 12, 2025 wasmCloud community call is a tooling-focused update for anyone building on the Wasm component model. Brooks Townsend demos a wadm reconciliation fix that takes local application deploys from around 15 seconds down to under one second by reacting to configuration events instead of waiting for a heartbeat. The team also marks the completion of the long-running merge of wash-cli and wash-lib into a single wash crate, previews wasmCloud's presence at KubeCon EU and WasmIO in Barcelona, and digs into tracing and observability for capability providers.
WebAssembly News: Merging the wash CLI and SBOM Build Provenance
The March 5, 2025 wasmCloud community call is a short, heads-down WebAssembly news update from a team in KubeCon EU crunch mode. Brooks Townsend walks through the in-progress effort — led by maintainer Ahmed — to merge the wash CLI and wash-lib crates into a single wash crate so features ship faster, and explains why the team is holding a feature freeze until the PR lands. Masoud, a wasmCloud OSS Fellow, shares phase-one progress on SBOM and build-provenance work for wasmCloud artifacts, which sparks a discussion with Taylor Thomas about keeping component builds compliant with the OCI artifact standard.
