It uses Bluetooth Low Energy mesh networking for offline communication (up to 7 hops, no internet required) and the Nostr protocol for global internet-based messaging. The app requires no accounts, phone numbers, or central servers. Key features include location-based channels using geohash coordinates, end-to-end encryption via the Noise Protocol and NIP-17, intelligent transport selection (Bluetooth preferred, Nostr fallback), emergency data wipe, and LZ4 message compression. Setup requires Xcode with a developer team ID configured. ## Full article daily.dev links to this article rather than hosting it.

People love pointing out the Streisand effect as though we’re still in the same social media dynamic that we were 30 or 15 years ago. Wake the fuck up. Banning the app is 100% certainly going to reduce it all’s usage. The fact that you somehow think you could have the opposite effect is a sign that your head is buried so deep in the sand and you have no idea what the current state of the world is. The authoritarians are winning and their censorship and propaganda has been exceptionally effective. Clinging to idealistic slogans and denying reality is a great way to accomplish nothing > — [nfbdhdfbf on hackernews · 3 comments](https://news.ycombinator.com/item?id=49050130) > Walked around Fusion Festival with Bitchat running. Saw about 20 other devices and a few messages. Nobody replied to my messages. So usage isn't zero, but 20 devices out of 80000 people isn't a lot. Most hops I saw was 2, meaning there wasn't enough density to make it any meaningful distance across the festival grounds. > — [inigyou on hackernews · 1 comments](https://news.ycombinator.com/item?id=49050377) > If they care so much about vendor locks maybe they should reconsider including libs.gms.location and be available on F-Droid (https://gitlab.com/fdroid/fdroiddata/-/merge_requests/24907#...) > — [plebian on hackernews](https://news.ycombinator.com/item?id=49049726) > the main reason they mentioned [1] for radicle.network is because their old domain radicle.xyz was blocked in some places by some lists that they think was because it may have hosted certain UGC that triggered some flags. > Content about Radicle (explainers, guides, download links, blog posts) which is under control of the Radicle team. We will use radicle.dev for these purposes. > Content on Radicle (repositories hosted on practically any node on the network) which the Radicle team has only very little control over, accessible via Radicle Explorer. Going forward, our deployment of Radicle Explorer will not be hosted on app.radicle.xyz anymore, but instead it will be hosted at radicle.network. > The idea is of course that if there are complaints about or issues with radicle.network in the future, we hope that radicle.dev stays largely unaffected and people can continue to inform themselves about Radicle and learn how to set it up. On a semi-related note, this is a good time to remind anyone that hasn't yet heard of the Public Suffix List (PSL) [2][3] to make sure you put your domains that may be hosting UGC in the form .. (ie: eTLDs) on that list so browsers and other block lists are aware that the user provisioned subdomains are UGC and not from your site so it properly isolates cookies/site grouping and won't flag your entire domain as malicious. 1: https://radicle.dev/2026/04/23/domain-move 2: https://en.wikipedia.org/wiki/Public_Suffix_List 3: https://github.com/publicsuffix/list > — [behindsight on hackernews · 1 comments](https://news.ycombinator.com/item?id=49049757) **Source threads** - [hackernews](https://news.ycombinator.com/item?id=49047365) · 71 points · 103 comments ## Similar posts on daily.dev - [bitchat](https://daily.dev/posts/bitchat-mjk4hiufp) · Hacker News · 0 upvotes · 0 comments - [Bitchat for Gaza - messaging without internet](https://daily.dev/posts/bitchat-for-gaza---messaging-without-internet-0wbsttkfa) · Hacker News · 0 upvotes · 0 comments - [X begins testing standalone X Chat app on iOS](https://daily.dev/posts/x-begins-testing-standalone-x-chat-app-on-ios-zamoxg74q) · TechCrunch · 0 upvotes · 0 comments - [Meshcore And Haiku: A Match Apparently Made In Italy](https://daily.dev/posts/meshcore-and-haiku-a-match-apparently-made-in-italy-lg1h8qct8) · Hackaday · 1 upvotes · 0 comments - [Seizing the means of messenger production](https://daily.dev/posts/seizing-the-means-of-messenger-production-9r784ont3) · Stack Overflow Blog · 0 upvotes · 0 comments --- Tags: [#ios](https://daily.dev/tags/ios), [#encryption](https://daily.dev/tags/encryption) [View this post on daily.dev](https://daily.dev/posts/bitchat-decentralized-mesh-messaging-ios-ljlulx49p) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"bitchat · Decentralized mesh messaging (iOS","url":"https://daily.dev/posts/bitchat-decentralized-mesh-messaging-ios-ljlulx49p","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/bitchat-decentralized-mesh-messaging-ios-ljlulx49p"},"datePublished":"2026-07-25T16:17:58.767Z","dateModified":"2026-07-25T19:14:01.542Z","description":"bitchat is an open-source, decentralized peer-to-peer messaging app for iOS and macOS with a dual transport architecture.
