Nymchat (Nostr Ynstant Messenger) yog ib daim ntawv thov kev sib tham uas muaj npe hu ua Nostr raws tu qauv. Nws tso cai rau koj sib txuas lus dawb yam tsis muaj npe, nyiaj, lossis Centralized servers.

Cov lus tau muab faib rau ntau pua lub zej zog ua haujlwm Nostr relays thoob ntiaj teb, ua lub network censorship-resistant thiab resilient. Cov keypairs ib ntus yog pib tsim txhua qhov kev sib kho rau siab tshaj plaws pseudonymity - koj nym ploj thaum koj disconnect.

Nymchat siv ephemeral kev sib txuas nkaus xwb. Cov keypairs ib ntus yog pib tsim kom siab tshaj plaws npe. Koj tus kheej muaj nyob tsuas yog rau qhov kev sib kho tam sim no thiab tsis muaj kab mob thaum koj txiav tawm. Tsis muaj nyiaj, tsis muaj npe, tsis muaj cov ntaub ntawv tsis tu ncua.

Nymchat siv ephemeral geohash thiab tsis yog-geohash raws - qhov chaw sib tham hauv chav siv geohash cov lej (piv txwv li, #w1, #dr5r). Cov no yog txuas nrog Bitchat thiab tuaj yeem txheeb xyuas los ntawm nyob ze rau koj qhov chaw nyob.

Tag nrho cov lus yog ib ntus thiab muaj nyob tsuas yog thaum lub sijhawm ua haujlwm, tsis muaj ib txoj hauv kev mus tas li.

Yog lawm. Cov apps hauv thiab iOS no suav nrog Bluetooth mesh: cov khoom siv ze ze txuas ncaj qha rau ib leeg dhau Bluetooth LE thiab relay cov lus dhia los ntawm hop, yog li cov lus tuaj yeem ncav cuag ib tus neeg txuas ntxiv mus dhau ntawm cov xov tooj nyob nruab nrab. Tsis muaj internet, tsis muaj cell service, tsis muaj infrastructure ntawm txhua yam.

Nws yog txuas nrog Bitchat, yog li Nymchat thiab Bitchat cov neeg siv sib koom tib lub mesh. Public channels thiab cov lus ntiag tug ob leeg ua haujlwm dhau nws. Thaum koj nyob online, cov lus nkag hauv internet txoj kev li niaj zaus thiab poob rov qab mus rau Bluetooth txiav thaum koj tsis yog.

Ghost Mode tshem koj tus kheej ntawm Bluetooth mesh. Feem ntau, koj lub tshuab qhia ib lub cim (identifier) uas ruaj khov, uas txhais tau tias txhua tus nyob hauv Bluetooth thiaj li paub koj thiab pom tias lub tshuab ntawd tshwm sim ntawm ntau qhov chaw sib txawv. Ghost Mode hloov txhua yam ntawm cov ntaub ntawv ntawd — lub cim tshuab, tus chaw tso npe (signing key), lub npe saib tau, thiab Nostr identity — nrog cov npe uas siv tsis ntev, thiab hloov mus los dua txhua tsib feeb.

Koj tseem tuaj yeem xa thiab tau txais cov lus thaum nws qhib. Cov phooj ywg pom tus neeg tsis qhia npe es tsis yog koj li ib txwm, thiab tsis tuaj yeem qhia nws yog koj. Tig nws rov ua rau koj li qub tus kheej. Nws yog tawm los ntawm lub neej ntawd thiab toggled los ntawm qhov screen mesh.

Nws yog ib qho kev zoo siab ntau, tsis yog ib qho kev lav tias yuav tseeb: koj lub xov tooj lub Bluetooth hardware address yog raug tswj los ntawm lub operating system, tsis yog los ntawm Nymchat, thiab cov kev coj xws li tus neeg koj tham thiab koj sau ntawv li cas tseem yuav paub tau. Ua rau nws raug saib tias yog ib qho ua rau koj nyuaj rau lwm tus raug nrhiav, tsis yog tias nws yog kev tsis muaj npe.

Cov lus ncaj qha hauv Nymchat siv Nostr's NPE-17 encryption txheem rau kawg-rau-kawg encrypted kev sib txuas lus uas tsis tuaj yeem txuas rau koj qhov kev sib tham. Tsuas yog koj thiab koj tus neeg txais yuav nyeem tau cov lus.

Kev sib tham pab pawg siv NIP-17 nrog kev txhim kho lub sijhawm tiv thaiv. Txhua tus tswv cuab tsim cov yuam sij ephemeral tau txais, thiab cov lus tau muab khoom plig qhwv ib tus neeg siv ib zaug siv cov yuam sij pej xeem. Qhov no tiv thaiv relays los ntawm correlating pab pawg neeg ua tswv cuab los yog txuas cov lus rau cov neeg tiag tiag. Cov tswvcuab tau tshaj tawm cov yuam sij tshiab rau kev rov ua haujlwm tom qab kev sib haum xeeb.

Ntawm Nymchat cov neeg siv, ob qho tib si PMs thiab pab pawg sib tham tuaj yeem siv quantum-resistant encryption — saib cov lus nug tom ntej.

Txhawm rau xa PM, siv lub /pm nym#xxxx hais kom ua lossis nyem rau ntawm tus neeg siv nym thiab xaiv "Private Message" los ntawm cov ntawv qhia zaub mov.

Txhua tus neeg siv tau txheeb xyuas los ntawm lawv cov nym + 4-tus cim cim los ntawm lawv tus lej pej xeem (piv txwv li, cyber_wolf#a3f2), kom ntseeg tau tias koj tuaj yeem paub qhov txawv ntawm cov neeg siv nrog cov npe zoo sib xws.

Rau cov lus ntiag tug thiab pab pawg sib tham ntawm Nymchat cov neeg siv, yog. Nymchat sib txuas cov qauv NIP-44 tseem ceeb pauv nrog ML-KEM-768, post-quantum algorithm standardized los ntawm NIST raws li FIPS 203. Ob leeg yuav tsum tau tawg los nyeem cov lus, yog li nws yog nyob ntawm tsawg kawg yog muaj zog li ua ntej thiab quantum-zoo rau saum.

Qhov no tseem ceeb vim hais tias "sau tam sim no, decrypt tom qab": tus yeeb ncuab tuaj yeem sau cov tsheb khiav nkag niaj hnub no thiab khaws cia kom txog rau thaum lub quantum computer tuaj yeem rhuav tshem qhov sib pauv elliptic-curve Nostr zoo tib yam encryption cia siab rau. Cov kev sib pauv hybrid txhais tau hais tias cov tsheb khiav yuav nyob twj ywm nyeem tsis tau.

Nws tiv thaiv cov cov ntsiab lus ntawm koj cov lus, tsis yog kos npe rau lawv. Nostr event Kev kos npe tseem yog secp256k1, yog li qhov no tsis yog qhov kev thov tias txhua feem ntawm cov txheej txheem yog quantum-pov thawj - tib txoj hauj lwm Teeb liab siv nrog nws tus kheej hloov kho tom qab quantum.

Nws yog tsis siv neeg - tsis muaj teeb tsa los qhib. Cov lus xa tawm no qhia me me ntaub thaiv npog ntawm lub xauv xauv. Cov neeg siv Bitchat thiab lwm tus neeg siv Nostr tsis cuam tshuam thiab khaws cia tau txais tus qauv NIP-17, yog li tsis muaj dab tsi tawg thaum koj xa ib tus neeg sab nraud Nymchat. Cov ib qho kev zam yog browser-extension thiab tej thaj chaw deb-signer logins, uas tsis tuaj yeem siv nws: cov cov kos npe xa rov qab cov lus tiav es tsis yog tus yuam sij peb tuaj yeem ua ke.

Yog tias koj siv tib tus account ntawm ntau tshaj ib lub cuab yeej, hloov kho lawv txhua tus: ib qho qub version ua tsis tau nyeem hom ntawv tshiab thiab yuav tsum tsis txhob tau txais koj cov lus kom txog thaum nws ua.

Nymchat txhawb cov phooj ywg-rau-peer suab thiab video hu hauv ob qho tib si 1: 1 cov lus ntiag tug thiab pawg sib tham. Media ntws ncaj qha ntawm cov neeg koom nrog WebRTC, thaum hu rau kev tswj hwm (thov caw, lees txais, ICE cov neeg sib tw) yog taw qhia los ntawm cov txheej xwm Nostr encrypted tagged rau txhua tus neeg tau txais - tsis muaj lub hauv paus hu rau server.

Txhawm rau pib hu, qhib cov lus ntiag tug lossis pab pawg sib tham thiab siv lub suab lossis video hu khawm hauv header. Kev hu tuaj ua rau lub nplhaib modal nrog tus hu tus nym; yog tsis teb, hu nws pib-tsis kam tom qab 45 vib nas this. Thaum hu koj tuaj yeem kaw lub microphone lossis toggle lub koob yees duab txhua lub sijhawm.

Suab hu thov lub microphone nkaus xwb; video hu thov ob lub koob yees duab thiab microphone ntawm qhov zoo tagnrho 1280 × 720 daws teeb meem. Hauv Chaw, koj tuaj yeem xaiv leej twg tso cai rau hu rau koj (txhua tus, phooj ywg nkaus xwb, lossis neeg xiam oob qhab) - "cov phooj ywg nkaus xwb" ntsiag to tsis quav ntsej hu los ntawm tsis yog phooj ywg.

⚠ Tsis pub twg paub ntawv ceeb toom: Vim tias kev hu xov tooj yog phooj ywg-rau-peer tshaj WebRTC, koj qhov tseeb IP chaw nyob yuav raug nthuav tawm rau lwm tus neeg sab nrauv (thiab rau lwm tus hauv pab pawg hu). Siv VPN lossis Tor yog tias koj xav tau zais nws.

Nymbot yog built-in AI tham bot. Koj tuaj yeem tham nrog nws hauv ob txoj kev:

• Pub dawb pej xeem-channel bot: Hom ?ask <question> los yog hais @Nymbot hauv txhua qhov channel. Quote-replying to Nymbot teb txuas ntxiv kev sib tham nrog lub ntsiab lus luv luv. Qhov no version khiav ib ib leeg-lub hom phiaj AI qauv thiab yog pub dawb rau siv.
• Premium Private Nymbot: Qhib tus kheej, kawg-rau-kawg encrypted 1: 1 tham nrog Nymbot (nias nws nym lossis avatar thiab xaiv "Private Message", lossis xaiv Nymbot los ntawm Nyms sidebar). Cov lus yog NIP-17 khoom plig-pob, yog li tsuas yog koj thiab bot tuaj yeem nyeem lawv. Nymbot tsis tuaj yeem muab ntxiv rau kev sib tham hauv pab pawg - kev sib tham ntiag tug yog 1:1 xwb.

Qhov hwm tus kheej bot yog a smarter, ntau tus qauv teeb: nws nyeem txhua lus, faib cov haujlwm (coding, laj thawj / lej, sau ntawv zoo, txhais lus, los yog kev sib tham dav dav) thiab coj nws mus rau qhov zoo tshaj plaws-haum rau cov qauv lus loj. Uas ua hwm teb cov lus ceeb toom sharper thiab muaj peev xwm ntau dua li cov pej xeem dawb bot. Ob leeg versions qhia tib lub vev xaib tshawb nrhiav thiab hloov pauv nkag rau huab cua tshiab, xov xwm, tus nqi, thiab cov ntaub ntawv kis las.

Tsis muaj tus thov xa xov: tus bot uas tsis pub tseem raug tso tawm los kuj ua ib lub app ntawm nws tus kheej ntawm nymbot.ai — tus pab cuam tib yam, tus account tib yam. Nrog tus chaw nkawm (key) tib yam uas koj siv mus, ces koj cov credits thiab cov lus sib tham yuav raug nrog koj mus qhov twg los xij.

Credits thiab nqi: Cov lus teb ntiag tug yog them nrog cov qhab nia, yuav ntawm Bitcoin Lightning zaps. Kev sib tham dav dav, muaj tswv yim sau ntawv, thiab txhais lus nqi 1 credit ib teb; coding thiab kev xav / lej raug nqi 2 khab nias (lawv siv cov qauv loj dua). Ib qho credit yog kwv yees li 10 zaum, nrog rau cov nyiaj tshwj xeeb me me ntawm cov nyiaj zap ntau dua (+ 10% ntawm 500 zaum, + 15% ntawm 1K, + 20% ntawm 5K). Siv ?buy mus sau npe, ?balance mus xyuas credit, thiab ?gift @nym xa credit rau lwm tus neeg siv. Hauv kev sib tham ntiag tug, ?clear wipes kev sib tham keeb kwm.

Nymchat integrates Lightning Network rau instant Bitcoin micropayments hu ua "zaps." Koj tuaj yeem qhia cov lus koj txaus siab lossis xa Bitcoin ncaj qha rau cov neeg siv.

Txhawm rau tau txais zaps, teeb tsa Lightning chaw nyob hauv Chaw (hom ntawv: user@domain.com). Xa ib zap, nyem tus neeg siv nym thiab xaiv "⚡ Zap" lossis siv khawm zap ceev uas tshwm ntawm cov lus nrog zaps uas twb muaj lawm.

Zaps tso tawm kom pom hauv lub sijhawm ntawm cov lus, qhia tag nrho cov nyiaj thiab tus lej ntawm zappers. Lub kaw lus tsim cov ntawv xa nyiaj xob laim txiav thiab saib xyuas cov xwm txheej them nyiaj.

Nymchat txhawb emoji cov lus teb rau cov lus (zoo ib yam li Discord lossis Slack). Nyem rau ntawm tus neeg siv lub nym thiab xaiv "React" lossis hla cov lus kom pom cov tshuaj tiv thaiv khawm.

Koj tuaj yeem hnov ​​mob nrog ib qho emoji los ntawm peb lub tsev qiv ntawv dav dav los ntawm qeb (smileys, gestures, lub siab lub ntsws, cov cim, thiab lwm yam). Tsis ntev los no emojis nco ntsoov rau kev nkag ceev.

Txhawm rau ntxig emojis hauv koj cov lus, ntaus : ua raws li lub npe (xws li :smile:) rau autocomplete, lossis nias lub pob emoji hauv thaj chaw nkag. Cov tshuaj tiv thaiv siv Nostr's NIP-25 tus qauv.

Nymchat txhawb nqa cov ntawv nplua nuj zoo ib yam li Discord lossis Slack:

• Bold: **text** los yog __text__
• Italic: *text* los yog _text_
• Strikethrough: ~~text~~
• Code: `code` los yog code blocks nrog ```code```
• Quotes: Pib kab nrog >
• Headers: # H1, ## H2, ### H3

Cov lus txib zoo li /bold, /italic, /quote, thiab /code muab shortcuts rau formatting ceev.

Thaiv cov neeg siv: Siv /block nym#xxxx los yog nyem tus neeg siv nym thiab xaiv "Block User." Thaiv cov neeg siv cov lus tau muab zais thiab lawv yuav tsis pom koj cov haujlwm.

Thaiv channels: Siv /block #channelname los yog /block thaum nyob rau hauv ib tug channel los thaiv nws. Thaiv cov channel tau muab zais los ntawm koj lub sidebar.

Block keywords: Ntxiv cov lus tseem ceeb hauv Chaw → Blocked Keywords los nkaum cov lus muaj cov lus tshwj xeeb lossis kab lus nyob hauv txhua txoj kev.

Saib thiab tswj cov blocks hauv Chaw.

Thaum qhib rau hauv Chaw, Nymchat tuaj yeem txheeb cov geohash raws nyob deb ntawm koj qhov chaw. Qhov no xav tau qhov browser tso cai.

Geohash channels yog qhov chaw sib tham hauv chav siv tus qauv geohash cov lej. Lawv yog txuas nrog Bitchat, tso cai rau kev sib txuas lus hla lub platform. Qhov sib thooj feature pab koj nrhiav thiab saib xyuas cov channel hauv zos.

Disable no feature txhua lub sij hawm nyob rau hauv tej chaw → "Xaiv Geohash Channels los ntawm qhov ze."

Qhia tawm channel URLs: Nias lub pob qhia nyob rau hauv lub channel header los yog siv /share tsim kom muaj qhov sib koom URL.

Caw rau cov channel tam sim no: Siv /invite nym#xxxx xa ib caw PM nrog cov ntsiab lus channel.

Nymchat muaj ntau lub ntsiab lus uas tau txais kev tshoov siab:

• Bitchat: Multicolor ntsiab nrog cov xim tshwj xeeb rau ib tus neeg siv (default)
• Matrix Green: Classic ntsuab-on-dub davhlau ya nyob twg zoo nkauj
• Amber Terminal: Vintage amber CRT screen tsos
• Cyberpunk: Neon liab thiab xiav xim tswvyim
• Hacker Blue: Blue-tinted Terminal ntsiab lus
• Dab: High-contrast hom dub thiab dawb

Kev hloov kho ntxiv suav nrog cov suab ceeb toom (Classic Beep, ICQ, MSN), pib-scroll tus cwj pwm, lub sij hawm tso saib, thiab cov duab plooj.

Nymchat muab qhov siab tshaj plaws pseudonymity los ntawm kev sib txuas ephemeral. Cov keypairs ib ntus raug tsim tawm ib zaug uas tsis muaj kev sib txuas rau koj tus kheej tiag. Cov lus tsis tau khaws cia tas mus li, thiab koj nym ploj thaum koj disconnect. Cov lus ncaj qha thiab pab pawg sib tham siv NIP-17 kawg-rau-kawg encryption nrog rotating ephemeral yawm sij thiab lub sij hawm nres tsis kam tiv thaiv kev sib raug zoo metadata.

Cov ntawv tseem ceeb: Cov lus channel pom tau rau txhua tus ntawm Nostr network. Siv PMs encrypted rau kev sib tham ntiag tug tiag tiag. Rau qhov siab tshaj plaws pseudonymity, siv Tor lossis VPN koj them rau kev siv nyiaj ntsuab lossis monero.

Identity encryption yog xaiv tau kev tiv thaiv rau qhov kev cawmdim tus kheej (nsec) tus yuam sij ntiag tug ntawm lub cuab yeej, yog li nws tsis tuaj yeem nyeem los ntawm qhov chaw cia khoom hauv zos yam tsis tau qhib. Koj xaiv qhov ntsuas xauv rau ib lub cuab yeej: tus password, tus PIN, tus password, lossis biometric.

• Passkey thiab biometric qhib siv WebAuthn nrog PRF txuas ntxiv rau muab tus yuam sij.
• Tus password thiab PIN siv PBKDF2.

Tus yuam sij tseem nyob hauv lub cim xeeb tsuas yog rau qhov kev sib kho, thiab tus yuam sij plaintext yeej tsis sau rau disk thaum encryption nyob rau. Tom qab koj qhib nws, lub app lees paub qhov qhib tam sim ntawd yog li koj nyob nraum tsis raug kaw yog tias tus neeg pov thawj lees paub tsis txhawb PRF.

Tsis muaj lo lus zais, ntsev, lossis daim ntawv pov thawj tau synced hla cov khoom siv. Tsuas yog ib qho kev nyiam rau / tawm syncs, yog li koj tuaj yeem xaiv los teeb tsa encryption ntawm lub cuab yeej tshiab.

Panic so hom cia koj tam sim ntawd rhuav tshem tag nrho cov ntaub ntawv hauv zos ntawm lub cuab yeej. Nias thiab tuav ntu "Koj Nym" rau 2 vib nas this kom ua rau nws.

Cov ntaub so yog dav. Nws encrypts txhua tus nqi cia hauv zos nrog tus yuam sij random ib zaug uas yog ces muab pov tseg, overwrites qhov tseem ceeb nrog junk, clears localStorage thiab sessionStorage, overwrites thiab deletes tag nrho IndexedDB databases, clears lub caches, unregisters tus neeg ua haujlwm pabcuam, thiab rov qab mus rau lub xeev tshiab thawj zaug.

Yog tias koj muaj tus kheej encryption enabled, kev tiv thaiv txuas ntxiv mus ntxiv: ib qho bytes uas ciaj sia tshem tawm yog ciphertext nyob rau hauv ib tug tseem ceeb tsis muaj leej twg tuav.

Nymchat muaj nyob rau hauv ib haiv neeg app thiab Progressive Web App (PWA):

• iOS no: Download tau los ntawm App Store (TestFlight)
• Android: Tau nws hauv Google Play los yog tau nws ntawm Zapstore
• PWA: Qhib web.nymchat.app nyob rau hauv koj tus browser thiab "Ntxiv rau Home Screen"

Lub mobile interface yog optimized nrog kov-phooj ywg tswj, los so gestures rau qhib lub sidebar, thiab cov lus teb layout uas yoog rau koj qhov screen loj. Tag nrho cov nta ua haujlwm mobile, nrog rau cov tshuaj tiv thaiv thiab zaps.

Nymchat yog txuas nrog Jack Dorsey's Bitchat daim ntawv thov, tshwj xeeb rau geohash-based qhov chaw channel. Qhov no txhais tau tias cov lus xa hauv geohash raws ntawm Nymchat tshwm hauv Bitchat thiab rov qab.

Tus choj tso cai hla kev sib txuas lus ntawm Nymchat lub web-based interface thiab Bitchat's mobile app, tsim kom muaj kev sib txuas sib txuas loj dua ntawm cov chav sib tham hauv qhov chaw siv tib Nostr raws tu qauv hauv qab.

Nymchat txuas mus rau ntau yam Nostr relays ib txhij rau redundancy thiab ceev:

• Tshaj tawm relays: Core relays rau kev xa xov (koj txuas nrog tag nrho lawv)
• Nyeem relays: Ntxiv relays nrhiav pom tau txais lus (txog 1000+)
• Nosflare: Sau-tsuas yog relay rau cov lus tshaj tawm

Lub app ntse tswj kev sib txuas, cia li nrhiav pom tshiab relays, blacklisting unresponsive relays, thiab retrying ua tsis tau tejyam kev twb kev txuas. Koj tuaj yeem saib txuas relays nyob rau hauv tej chaw.

Ntau relays = zoo dua censorship kuj thiab xa xov, tab sis kuj bandwidth ntau dua kev siv.
