How about simultaneously running a UTREEXO Lightning node, a Pubky homeserver, and CUBE on this:

All three of these are awesome projects.

The architecture of Pubky beats Nostr hands down.

Imagine being able to plug a <$70 touchscreen lightning node (perhaps a kit from waveshare_dot_com) into a plug socket in your living room or study. Utreexo is a lightning-compatible scaling improvement for Bitcoin that dramatically reduces storage requirements for full nodes by replacing the entire UTXO set with a compact Merkle tree-based hash accumulator. Utreexo nodes store only a few kilobytes of root hashes. This is a non-consensus-changing optimization (not even a soft fork) that makes full nodes more streamlined and scalable for billions of users. It trades storage for 1.7x increased bandwidth.

Pubky is a decentralized Ed25519 key-based web platform that puts users in control of their identity and data by combining PKARR (Public Key Addressable Resource Records) for self-sovereign identity with homeservers for censorship-resistant hosting. Pubky doesn't depend on centralised relays like NOSTR. Instead, it uses [kademlia-mediated] mesh & peer-based Semantic Social Graphing for elastic (weighted) filtering and discovery. The Progressive Web App approach overcomes government mandated walled-gardens, while Ed25519 keys provide native data interchange opportunities with Reticulum, Meshtastic, Meshcore etc. Pubky's public beta is now open and a Pubky Marketplaces stack is scheduled for later this year.

Cube is a new L2 for Bitcoin conceptualised by Burak (who created Ark). It extends Bitcoin’s native self-custody and settlement model into a programmable execution environment while remaining fundamentally anchored to Bitcoin itself. Cube’s execution architecture is the composition of two Bitcoin-native primitives: (1) Ark-style timeout-tree ownership virtualization and (2) BitVM-style disprovable computation. CAUTION: This medium article is pretty complicated, but we wouldn't expect anything less from its author xD
