Avaldatud<\/a><\/noindex> detsentraliseeritud failis\u00fcsteemi v\u00e4ljaanne IPFS 0.6<\/a><\/noindex> (InterPlanetary File System), mis loob globaalset versioonitud failide hoiust, mis on \u00fcles seatud P2P-v\u00f5rguna, mis koosneb osalejate s\u00fcsteemidest. IPFS \u00fchendab ideid, mida on varem rakendatud sellistes s\u00fcsteemides nagu Git, BitTorrent, Kademlia, SFS ja Web, ning meenutab \u00fchte \"vraki\" BitTorrentis (peerid, kes osalevad jagamises), vahetades Git-objekte. IPFS eristub sisu, mitte asukoha ja suvaliste nimede j\u00e4rgi adresseerimise poolest. Standardse teostuse kood on kirjutatud Go keeles ja levitatakse<\/a><\/noindex> on litsentside alla Apache 2.0 ja MIT.<\/p>\n

Uus versioon on m\u00e4rkimisv\u00e4\u00e4rne vaikimisi protokolli p\u00f5hineva transpordi lisamisega QUIC<\/a><\/noindex>, mis on UDP protokolli peal olev kiht, toetades mitme \u00fchenduse multiplexerimist ja pakkudes kr\u00fcpteerimismeetodeid, mis on v\u00f5rreldavad TLS\/SSL-iga. IPFS-is k\u00e4ivitatakse UDP-\u00fchenduste vastuv\u00f5tu sokkel automaatselt samal aadressil ja v\u00f5rguportil, kus asub TCP-p\u00f5hine transpordihaldur. QUIC-i kasutatakse nii sissetulevates kui ka v\u00e4ljuvates \u00fchendustes ning uute s\u00f5lmede \u00fchendamisel, kui QUIC pole saadaval, l\u00fclitub see tagasi TCP kasutamiseks.<\/p>\n

Teiseks oluliseks uuenduseks on turvalise transpordi tugi NOISE<\/a><\/noindex>, mis p\u00f5hineb<\/a><\/noindex> protokollil Noise<\/a><\/noindex> ja arendatakse raames libp2p<\/a><\/noindex>, modulaarse v\u00f5rgu stack'i jaoks P2P-rakendustes. P\u00e4rast algset \u00fchenduse v\u00e4\u00e4rtustamist kr\u00fcpteeritakse kogu edasine andmevahetus osaliste vahel ja kaitstakse pealtkuulamise eest.
\nNOISE tuli transpordi asemele SECIO<\/a><\/noindex>, kuid s\u00f5lmede vaheliste \u00fchenduste kr\u00fcpteerimismeetodina kasutatakse ikka veel TLS 1.3. NOISE on piisavalt lihtne rakendada ja positsioneeritakse universaalseks ristplatvormiliseks transpordiks, mis saab olla rakendatud erinevates programmeerimiskeeltes.<\/p>\n

Uues numbris on samuti lisatud v\u00f5imalus lisada omaenda lehti «404 Not Found» ning lisatud valikuline toetus Base36 kodeerimismeetodile, mis on optimaalselt sobilik suurt\u00e4htede ja v\u00e4iket\u00e4htede eristamata alfanumeeriliste andmete, nagu domeenide nimede, jaoks (Base32 kasutades \u00fcletavad Ed25519 IPNS v\u00f5tmed kahest baitist \u00fcle, piiratud alamdomeeni suuruses, samas kui Base36 mahub piiridesse). Lisaks on seadistusvalikutesse lisatud valik.
\n\u00abpeering<\/a><\/noindex>« mis m\u00e4\u00e4ratleb s\u00f5lmede loendi, millega \u00fchenduse loomine, s\u00e4ilitamine ja uuesti\u00fchendamine on ette n\u00e4htud, et m\u00e4\u00e4rata «liimivad» sidemed sageli kasutatavate peer'ide vahel.<\/p>\n

Tulet meelde, et IPFS-is on faili juurde p\u00e4\u00e4semiseks link otseselt seotud selle sisuga ja sisaldab sisu kr\u00fcptograafilist j\u00e4rgnumust. Faili aadressi ei saa lihtsalt \u00fcmber nimetada, see v\u00f5ib muutuda ainult sisu muutmisel. Samuti ei saa faili muuta ilma aadressi muutmiseta (vana versioon j\u00e4\u00e4b oma aadressile, uus on saadaval teise aadressi kaudu, kuna faili sisu hash muutub). Arvestades, et faili identifikaator muutub igasuguse muudatuse korral, et v\u00e4ltida uute linkide pidevat jagamist, on saadaval teenused, mis seovad p\u00fcsivaid aadresse, arvestades erinevaid faili versioone. IPFS-i globaalsetesse failis\u00fcsteemidesse p\u00e4\u00e4seb ligi HTTP-protokolli kaudu v\u00f5i saab virtuaalse failis\u00fcsteemi \\\/ipfs monteerida FUSE-i mooduli abil.IPNS<\/a><\/noindex>), v\u00f5i kinnitavad h\u00fc\u00fcdnime sarnastele traditsioonilistele failis\u00fcsteemidele ja DNS-ile (MFS<\/a><\/noindex> (Mutable File System) ja DNSLink<\/a><\/noindex>). <\/p>\n

Sarnaselt BitTorrentile s\u00e4ilitavad andmed otse osalejate s\u00fcsteemides, kes vahetavad teavet P2P-re\u017eiimis, ilma kesksete s\u00f5lmedeta. Kui on vaja faili kindla sisuga saada, leiab s\u00fcsteem osalejad, kellel see fail on, ning edastab selle nende s\u00fcsteemidest osade kaupa mitmes voos. P\u00e4rast faili laadimist oma s\u00fcsteemi muutub osaleja automaatselt \u00fcheks jagamise punktiks. N\u00f5udlikku sisu leidmiseks jagatud hashtabelis ( kasutatakse<\/a><\/noindex> DHTDHT<\/a><\/noindex>IPFS aitab lahendada probleeme nagu andmete usaldusv\u00e4\u00e4rne salvestamine (kui algne salvestus koht on h\u00e4vitatud, saab faili \u00fcles laadida teiste kasutajate s\u00fcsteemidest), sisu tsenseerimisele vastupidamine (k\u00f5igi andmete koopiate blokeerimiseks tuleb blokeerida k\u00f5ik kasutajate s\u00fcsteemid, kus koopiad asuvad) ja juurdep\u00e4\u00e4su korraldamine, kui interneti otse\u00fchendus puudub v\u00f5i sideteenuse kvaliteet on halb (andmeid saab \u00fcles laadida l\u00e4himatega kohalikus v\u00f5rgus). Lisaks failide salvestamisele ja andmete jagamisele saab IPFS-i kasutada ka uute teenuste loomise aluseks, n\u00e4iteks serveriteta veebisaitide t\u00f6\u00f6 korraldamiseks v\u00f5i jaotatud s\u00fcsteemide loomiseks. <\/p>\n
