Pas-pas ɛvri ɛnkriptid mesinjɛ we pɔpju-lar de yus, dɛn tin dɛn tin ɛkspekt ɔ wan sɛvɔ (server) dɛn de kan ritch. Kat di konekshɔn — ɔ wan ɛshat-dan, ɔ lɛt-kɔt, ɔ wan stadiyam, ɔ wan subway, ɔ wan huriken — di ap go wan blɛnk skrin. Nymchat bɔlt so dat de mɔment di ɛnfra-strakshɔ de go aw, na de mɔment ɛti de mos yuful.

Wɛn di netwɔk kɔm dɔn, di ap dɔn no

Binit di dewan internet transport, Nymchat de run wan Bluetooth LE meshDɛn disayz we de naya to wan, dɛn de kɔnɛkt dɛm dɛkɛktli ɛn dɛn de rɛlay fɔ dɛn ɔda, so wan mesij kin riich ɔda wan we de fɔm wan ples we de far we radio nɔ kin riich, ɛn i de jɔmp fɔm wan fon to ɔda fɔ riich dɛm — i kin jɔmp ɔp to sɛven tɛm, ɛn ɛvri pɛa fɔ dɛn disayz de rɔn in in ɛnkrɪptɛd Noise XX sɛʃɛn. No inṭānet, no sɛl sɛrvɪs, ɛn no wan kɛnd ɔf ɛnfrastraktʃa de pan dɛn. Pɔblɪk tʃanal ɛn praɪvɪt mesij dɛn ɔl kin wōk pan dɛn, ɛn di ap de pil di rɔt ɛn sɛlf: wen yu de ɔnlayn, di mesij de go ɔvā di nɛtwerk, ɛn wen nɔ de nɛtwerk, i go go ɔvā Bluetooth.

Nymchat de yuz de seym mesh protokol se Bitchat, Jack Dorsey Bluetooth mesh app, bɛt fɔ bɛt na de wire. Di tu app nɔ de kɔnek tɛn di am tɔn — dɛm de na di sɛm mesh, dɛm de fɛnd ɛch ɔda and dɛm de ɛksʧenj ɛnkrip-tɛd mesij dɛk-tɛk, wetin mek di oflayn netwɔk biggɛ na fɔ bot. Bitchat na wan sɛparet prɔʤɛkt wetin ɛn ɔna ɔna na fɔ mɛstɛ; Nymchat de kɔmpatibl wit am, dɛm nɔ de rili kɔnek wit am.

Di mesh de wok as ful peer na Android an iOS, an as leaf na Chromium browsers, wey kin konekt go out to fone wey de near, but dem no kin advertise demself.

Nɔ ɛkɔnt fɔ klɔːz, an nɔ dɛrɛktɔri fɔ lĩk

No Nymchat akount den, bikos no Nymchat serfa we go kip wan. Wan identity na wan keypair we de mek na di device. Di default na wan efemiral nym — we de mek wen di app opin an de go aw wen di sesin en — an enriwan we wan gat wan identity we de de fɔr longa time kin bring wan Nostr ki instɛd.

Gɔst Mɔd Di mesh de do pass di oda tin: di signing key, di peer identifier, di Bluetooth name we dem de show, and di nickname, dem all de change for oda tin we dem no go use again, and dem de change dem evri fiv-tin minits, so e go dif for follow wan diti wen e de move bak and for bak or froom wan session to an oda. Na di diti de, yu kin lock di identity we yu save wit password, PIN, passkey, or biometric, and if yu du 'panic wipe', e de wipe en sing we de na di diti — e de lock en sing we de na di diti wit wan key we yu de use wan taim only, den e de throw di key away, e de write en top, and e de mek di diti bak de oda dia (fres/first-run state).

Enkripshen we de tink abaut kwantɔm kɔmpjuta ɔlredy

Privey mesij en grup tɔk dɛn lok wan-tu-wan en dɛn wrap dɛm gud: evey kopi dɛn de sign am wit wan wan-taim ki dɛn mek fɔ dat mesij wan, en dɛn de put di taem baka wan-tu-a fɔ mek i no de lɔk, fɔ mek di pɔst-man dɛn we de keri di tɔk, dɛn no go de kian rɛd am, en dɛn no go sabi wan fɔ wan dɛn de tɔk. Di grup tɔk dɛn de sɛn fɔ ɔl-ni-taim ki fɔ di pɔsin dɛn we de rɛsiv di mesij, fɔ mek di lɔst di pɔsin dɛn we de na di grup no de mek wan patan we di pɔst-man dɛn de kian si.

Botwin Nymchat usuz, di enkripshen na mix post-quantum: di stándad secp256k1 ekseinj stɛy ɛksakt de mɛn as i de, an ML-KEM-768, ɛn di ɔda wan dɛn — di algoriti NIST mek am de standard na FIPS 203 — kii dem de mek wan oda laye we de wrap round am, so if pɔsin wan tek am, e go hafe di break bot dem. Dat de stop di "kole am naw, di-kod am lata" tin, we de mek pɔsin kɔlet di tin we de pas nɔmɔ na tɔdey, den de kɔp am go tɛl sɔmti we kuantɔm kɔmputa go de bɛk di ɛlɪptɪk-kɜːv matɛmæteks we ordinary Nostr ɛnkrɪpʃɔn de rɪplaɪ on. No tin we yu go hafe di tɔn on, and no tin de bɛk fɔ ɔda pipul: mesɪʤ na Bitchat usas ɛn ɔda Nostr klayɛnt dem go fɔl bak na di stændad NIP-17. Na dis tɛm we am de rit, no ɔda Nostr klayɛnt nɔ de ɛkɔs am.

Wan ful messenger, no be survival tool

Di offline mode na wan baksup inside wan ful app, no na di hole produkt. Nymchat de do wan-tu-wan and grup audio and video kɔl, we de am fɔ am wit sek-kyur (encrypted) way, den de go direkt beta di pipul de am fɔ am de, wit no server in di midul. I get imaj, video and fayl trasnfer, pol, riyaksun, rip-lay, mesij we de go away, mesij trasle-shun na mɔ di hɔn-dred langwej, sik tem we de luk layk terminal, blɔk list, kii-wɔd fita, and ripɔting.

Bitcoin pepay de na part pan di konversashon: a Laitning katch e sen sats to wan gud post o to wan osun, am go setul bwtin di tu wallet na sekon. Nymbot, di AI assistant we de inside, gi ansaw frì in ɛni pɔblik chanèl an de kɛp ɛn ɛnd-tu-ɛn ɛnkriptid prɪvɛt konvɛsɛshon fɔ ɛniwan we bɔy krɛdɪt ɔvə Lightning.

Yu kin check am, no na jus de claim am

Nymchat na fri softwer we de unda AGPL-3.0, and di ol wan de publis — di web app wetin de run na di web, and di Flutter app fɔ Android and iOS, wetin nɔ get eni kɔnsidɛn (closed component) we yu go fɔ jus tɔst. Di web build de mek yu ɛn fɔ mek am sef: ɛvri asset de in manifest wit hash, wan GitHub Action de ríbìld ɛvri kɔmit ɔndipɛndɛntli and in sɛn di build-provenance attestations, and di app sɛf 'About' dialog de rē-hash di fayl we in de rɔn, in de rē-kɔmpjuut di bundle hash frɔm wetin in jus mɛsɔ, and in de luk dat na di repository sɛnd (signed) attestations. Wan deployment nɔ ɛf kɛn se e de kɔrɛkt fɔ ɔn sɛf, and wan mirror na ɔda domain de se dat klɔs fɔ mek yu no tink se na di ofisal app de. Na Android, wan APK we yu instal frɔm Zapstore de kɛn ɛksɛk (check) wit di SHA-256 we de publis na wan sɛnd (signed) Nostr event.

Wan warrant canary, we dem sign am den tie am na wan nyu Bitcoin block so e nɔ go de de sign am boku bifo, dem put am na di repository den di app de ridi am live.
