Beaxplorer is an Ethereum Beacon chain explorer written in Rust and relying on Lighthouse.
It's split into two distinct components: An indexer and a web UI. But there is a twist: Unlike other Beacon chain explorers, the web UI is client side only, there is no backend, no SQL database. Instead, the indexer serialize the data it extract from the Beacon chain into MessagePack files that served on a static website and deserialized directly on the browser using Rust's WebAssembly capabilities.
