Prezentat<\/a><\/noindex> lansarea sistemului de fi\u0219iere descentralizat IPFS 0.7<\/a><\/noindex> (InterPlanetary File System), form\u00e2nd un depozit global de fi\u0219iere versiunate, desf\u0103\u0219urat sub form\u0103 de re\u021bea P2P, constituit\u0103 din sistemele participan\u021bilor. IPFS combin\u0103 idei realizate anterior \u00een astfel de sisteme ca Git, BitTorrent, Kademlia, SFS \u0219i Web, \u0219i aminte\u0219te de un «raib\u0103» BitTorrent (seeds care particip\u0103 la distribu\u021bie), schimb\u00e2nd obiecte Git. IPFS se distinge prin adresarea pe baza con\u021binutului, nu a loca\u021biei, \u0219i a numelui arbitrar. Codul de referin\u021b\u0103 este scris \u00een limbajul Go \u0219i se r\u0103sp\u00e2nde\u0219te<\/a><\/noindex> licen\u021biat sub Apache 2.0 \u0219i MIT.<\/p>\n

\u00cen noua versiune, transportul este dezactivat implicit. SECIO<\/a><\/noindex>, \u00eenlocuind transportul propus \u00een versiunea anterioar\u0103. NOISE<\/a><\/noindex>, bazat<\/a><\/noindex> protocolul Noise<\/a><\/noindex> \u0219i dezvoltat \u00een cadrul unui stive de re\u021bea modulare pentru aplica\u021bii P2P. libp2p<\/a><\/noindex>. Ca transport de rezerv\u0103, a fost men\u021binut TLSv1.3. Administratorii nodurilor care utilizeaz\u0103 versiuni mai vechi de IPFS (Go IPFS < 0.5 sau JS IPFS < 0.47) sunt sf\u0103tui\u021bi s\u0103-\u0219i actualizeze software-ul pentru a evita o sc\u0103dere a performan\u021bei.<\/p>\n

\u00cen noua versiune, s-a realizat \u0219i trecerea la utilizarea cheilor ed25519 ca standard \u00een loc de RSA. Suportul pentru vechile chei RSA este men\u021binut, dar noile chei vor fi acum generate folosind algoritmul ed25519. Utilizarea cheilor publice ed25519 \u00eencorporate rezolv\u0103 problema stoc\u0103rii cheilor publice, de exemplu, pentru verificarea datelor semnate, fiind suficient\u0103 informa\u021bia despre PeerId. Numele cheii \u00een c\u0103ile IPNS sunt acum codificate folosind algoritmul base36 CIDv1 \u00een loc de base58btc.<\/p>\n

Pe l\u00e2ng\u0103 schimbarea tipului de chei implicit \u00een IPFS 0.7, a fost ad\u0103ugat\u0103 capacitatea de rotire a cheilor de identificare. Pentru a schimba cheia nodului, acum se poate executa comanda «ipfs key rotate». De asemenea, au fost ad\u0103ugate comenzi noi pentru importul \u0219i exportul cheilor («ipfs key import» \u0219i «ipfs key export»), care pot fi utilizate pentru backup, precum \u0219i comanda «ipfs dag stat» pentru a prezenta statistici despre DAG (Grafuri Aclucide Distribuite).<\/p>\n

Reamintim c\u0103 \u00een IPFS, linkul pentru accesarea unui fi\u0219ier este direct legat de con\u021binutul s\u0103u \u0219i include un hash criptografic al con\u021binutului. Adresa fi\u0219ierului nu poate fi redenumit\u0103 aleatoriu, poate fi modificat\u0103 doar dup\u0103 ce con\u021binutul s-a schimbat. \u00cen mod similar, nu se poate efectua o modificare a fi\u0219ierului f\u0103r\u0103 a schimba adresa (versiunea veche va r\u0103m\u00e2ne la aceea\u0219i adres\u0103, iar noua va fi accesibil\u0103 printr-o alt\u0103 adres\u0103, deoarece hash-ul con\u021binutului fi\u0219ierului se va schimba). Av\u00e2nd \u00een vedere c\u0103 identificatorul fi\u0219ierului se schimb\u0103 cu fiecare modificare, pentru a nu transmite \u00een mod constant linkuri noi, sunt furnizate servicii pentru a lega adresele permanente, care \u021bin cont de diferitele versiuni ale fi\u0219ierului (IPNS<\/a><\/noindex>), sau pentru a fixa un alias similar cu FS-urile tradi\u021bionale \u0219i DNS (MFS<\/a><\/noindex> (Sistem de Fi\u0219iere Mutable) \u0219i DNSLink<\/a><\/noindex>). <\/p>\n

Pe modelul BitTorrent, datele sunt stocate direct pe sistemele participan\u021bilor, care schimb\u0103 informa\u021bii \u00een mod P2P, f\u0103r\u0103 a fi legate de noduri centralizate. C\u00e2nd este necesar s\u0103 se ob\u021bin\u0103 un fi\u0219ier cu un anumit con\u021binut, sistemul g\u0103se\u0219te participan\u021bii care au acel fi\u0219ier \u0219i \u00eel ofer\u0103 din sistemele lor \u00een buc\u0103\u021bi, pe mai multe fluxuri. Dup\u0103 ce un participant a desc\u0103rcat fi\u0219ierul pe sistemul s\u0103u, devine automat unul dintre nodurile de distribu\u021bie a acestuia. Pentru a determina participan\u021bii din re\u021bea pe nodurile c\u0103rora exist\u0103 con\u021binutul de interes se folose\u0219te<\/a><\/noindex> se folose\u0219te o tabel\u0103 de hash distribuit\u0103 (DHT<\/a><\/noindex>). Pentru accesul la FS-ul global, IPFS poate folosi protocolul HTTP sau poate fi montat o FS virtual\u0103 \/ipfs prin intermediul modulului FUSE. <\/p>\n

IPFS ajut\u0103 la rezolvarea unor probleme, cum ar fi fiabilitatea stoc\u0103rii (dac\u0103 sursa ini\u021bial\u0103 de stocare este defect\u0103, fi\u0219ierul poate fi desc\u0103rcat din sistemele altor utilizatori), rezisten\u021ba la cenzurarea con\u021binutului (pentru a bloca ar necesita blocarea tuturor sistemelor utilizatorilor care de\u021bin o copie a datelor) \u0219i organizarea accesului \u00een absen\u021ba unei conexiuni directe la internet sau \u00een condi\u021bii de calitate slab\u0103 a canalului de comunica\u021bie (datele pot fi desc\u0103rcate prin intermediul celor mai apropia\u021bi participan\u021bi din re\u021beaua local\u0103). Pe l\u00e2ng\u0103 stocarea fi\u0219ierelor \u0219i schimbul de date, IPFS poate fi folosit ca baz\u0103 pentru crearea de noi servicii, de exemplu, pentru organizarea func\u021bion\u0103rii site-urilor nelegate de servere sau pentru crearea de aplica\u021bii distribuite. aplica\u021bii<\/a><\/noindex>.<\/p>\n
