In an era of pervasive surveillance, the line between citizen and subject is increasingly questionable. In a p2p distributed system the line between peer and "user" is much more concise and distinct. Be a peer.

Join us on Reddit in 1 hour for an Ergo AMA! https://www.reddit.com/r/ergonauts/comments/1qu5hxg/ergonauts_reddit_ama_february_5th_1700_utc/ View quoted note →

We spent years trying to convince “crypto” to care about cryptographically hard assets and trust-minimized derivatives instead of endlessly printed insider junk that makes fiat look honest. Ergo had to survive in a grift-heavy ecosystem built around exchanges and speculation. That phase is ending. Fundamentals matter again.

Runes give Bitcoin a clean, UTXO-native token layer. Rosen Bridge brings a cross-chain control plane with Watchers and Guards. Put them together and you get wrapped assets that live on #Bitcoin as #Runes, travel across chains, and redeem back through verifiable flows. 🔸 First demo with ADA, funded by Cardano Catalyst, proved the full loop by locking on Cardano and minting a Rune on Bitcoin with Rosen metadata. This isn’t a science project. It’s a #bridge design that traders, devs, and DAOs can use today. Read the full article 👉
