Stacker News Cowboy Credits Market Depth ![](https://m.stacker.news/121473) I noticed an increasing demand for ccs/sats trades so I thought, as [0xbitcoiner](), about finding an easy way to keep track of requests and visualize the data. The current market includes orders from @0xbitcoiner, @Darthcoin, @ek, @nokness, @SimpleStacker, @Undisciplined, @thebullishbitcoiner, and myself. I invite anyone looking to trade ccs for sats and vice versa to add a comment below, [open an issue]() in the GH repository, or simply [submit a PR](). Here a template if needed; ``` Title: New Market Order // Example: I'm buying 50 CC for 30 sats - Username: @yourNym - Type: buy - CC: 50 - Sats: 30 - Post: https://stacker.news/items/0000000 ``` Stay humble, stack sats

The Gossip Vulnerability: Why NIP-17's "Deniable" Messages Aren't ![](https://m.stacker.news/118485) # What This Means for Nostr > The Nostr community should acknowledge this tradeoff explicitly. NIP-17 is excellent for censorship resistance and metadata privacy, but it's not suitable for truly deniable communications. Users needing real deniability should use Signal or Session. > > The unsigned "rumor" provides psychological comfort but no cryptographic protection. The signed seal is the vulnerability, and it's unfixable without redesigning Nostr's entire authentication model. > > This isn't a failure, it's physics. Cryptography has limits. The impossible triangle of decentralized, authenticated, and deniable messaging is truly impossible. Every protocol must choose its compromises. > > Nostr chose decentralization and authentication. That's a valid choice. But calling the messages "deniable" because the inner layer is unsigned? That's not cryptography, that's marketing. > > The gossip attack is real. The ZK proof works. And the rumor isn't deniable after all.
