Everyone’s rediscovering that putting everything on one megacorp server has downsides. Federation isn’t a magic cure — it shifts the incentive structure. When you host your own node the trade-offs between convenience, control, and community become yours to choose.

Linkiny’s federation is WhatsApp-simple at the surface. You add a contact by their domain. Messages deliver in real time. Blog posts and listings from your node appear on other peers’ Discover feeds if you made them public. Search spans the federation (cached with explicit TTLs).

Under the hood it’s boring: signed JSON POSTs between nodes, mutual TLS, retry queues. The interesting part is the product: one UX across self-hosted and managed, one identity across chat and blog, one code path across web and iOS.
