GNS can operate alongside DNS and be utilized in traditional applications like web browsers. Unlike DNS, GNS uses a directed graph instead of a tree-like hierarchy of servers. Name resolution is similar to DNS, but requests and responses are handled with privacy in mind \u2014 the node processing the request does not know who receives the response, and transit nodes and third-party observers cannot decipher the requests and responses. The integrity and immutability of records are ensured through cryptographic mechanisms. A DNS zone in GNS is defined using a pair of ECDSA public and private keys based on the elliptic curve Curve25519.                   <\/li>\n<li class=\"l\"> Egy anonim f\u00e1jlmegoszt\u00f3 szolg\u00e1ltat\u00e1s, amely megakad\u00e1lyozza az inform\u00e1ci\u00f3k elemz\u00e9s\u00e9t, mivel az adatokat csak titkos\u00edtott form\u00e1ban tov\u00e1bb\u00edtja, \u00e9s nem teszi lehet\u0151v\u00e9 a f\u00e1jlok k\u00f6zz\u00e9t\u00e9tel\u00e9nek, keres\u00e9s\u00e9nek \u00e9s let\u00f6lt\u00e9s\u00e9nek nyomon k\u00f6vet\u00e9s\u00e9t a GAP protokoll haszn\u00e1lat\u00e1nak k\u00f6sz\u00f6nhet\u0151en.   <\/li>\n<li class=\"l\"> Rendszer <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/hu\/vpn\/\"   title=\"VPN\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"204\">VPN<\/a> for creating hidden services in the '.gnu' domain and tunneling IPv4 and IPv6 over a P2P network. Additionally, IPv4-to-IPv6 and IPv6-to-IPv4 translation schemes are supported, as well as tunneling IPv4 over IPv6 and IPv6 over IPv4.      <\/li>\n<li class=\"l\"> The GNUnet Conversation service enables voice calls over GNUnet. GNS is used for user identification, and the content of voice traffic is transmitted in encrypted form. Anonymity is not currently provided \u2014 other peers can track the connection between two users and identify them. <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/hu\/lir\/ipv4\/\"   title=\"IP address\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"699\">IP address<\/a>.  <\/li>\n<li class=\"l\"> A Secushare platform for building decentralized social networks, utilizing the PSYC protocol and supporting multicast notification distribution with end-to-end encryption, ensuring that access to messages, files, chats, and discussions is granted only to authorized users (those to whom messages are not addressed, including node administrators, will not be able to read them);    <\/li>\n<li class=\"l\"> A system for organizing encrypted email called pretty Easy privacy, employing GNUnet to protect metadata and supporting various cryptographic protocols for key verification;    <\/li>\n<li class=\"l\"> The GNU Taler payment system, providing anonymity for buyers while tracking vendor transactions for transparency and tax reporting.

A new type of record, REDIRECT, has been introduced to replace CNAME records. A new record flag \u2014 CRITICAL \u2014 has been added to mark particularly important records, the failure to process which should result in a name resolution error. VPN tunnel installation operations have been moved from the resolver to applications such as the DNS2GNS service.\n<li class=\"l\"> A capability for route assurance via digital signatures has been implemented in the distributed hash table (DHT). Metrics on route length have been transitioned to using traditional XOR operations. The specification for data structures, cryptographic functions, and DHT resource records has been updated.\n<li class=\"l\"> The decentralized attribute exchange service (RECLAIM) has added support for decentralized identifiers (DID) and verifiable credentials (VC).\n<li class=\"l\"> Support for Klaus Schnorr's blind digital signatures (the signer cannot access the contents) has been implemented in the GNU Taler payment system.\n<li class=\"l\"> The build system has been enhanced to generate up-to-date header files from GANA (GNUnet Assigned Numbers Authority). When building from git, recutils is now required.    <\/ul>\n<p>Forr\u00e1s: <a content=\"nofollow\" rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=56767\">opennet.ru<\/a> <\/p>","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"excerpt":{"rendered":"<p>\u041f\u0440\u0435\u0434\u0441\u0442\u0430\u0432\u043b\u0435\u043d \u0432\u044b\u043f\u0443\u0441\u043a \u0444\u0440\u0435\u0439\u043c\u0432\u043e\u0440\u043a\u0430 GNUnet 0.16, \u043f\u0440\u0435\u0434\u043d\u0430\u0437\u043d\u0430\u0447\u0435\u043d\u043d\u043e\u0433\u043e \u0434\u043b\u044f \u043f\u043e\u0441\u0442\u0440\u043e\u0435\u043d\u0438\u044f \u0437\u0430\u0449\u0438\u0449\u0451\u043d\u043d\u044b\u0445 \u0434\u0435\u0446\u0435\u043d\u0442\u0440\u0430\u043b\u0438\u0437\u043e\u0432\u0430\u043d\u043d\u044b\u0445 P2P-\u0441\u0435\u0442\u0435\u0439. \u0421\u043e\u0437\u0434\u0430\u0432\u0430\u0435\u043c\u044b\u0435 \u043f\u0440\u0438 \u043f\u043e\u043c\u043e\u0449\u0438 GNUnet \u0441\u0435\u0442\u0438 \u043d\u0435 \u0438\u043c\u0435\u044e\u0442 \u0435\u0434\u0438\u043d\u043e\u0439 \u0442\u043e\u0447\u043a\u0438 \u043e\u0442\u043a\u0430\u0437\u0430 \u0438 \u0441\u043f\u043e\u0441\u043e\u0431\u043d\u044b \u0433\u0430\u0440\u0430\u043d\u0442\u0438\u0440\u043e\u0432\u0430\u0442\u044c \u043d\u0435\u043f\u0440\u0438\u043a\u043e\u0441\u043d\u043e\u0432\u0435\u043d\u043d\u043e\u0441\u0442\u044c \u0447\u0430\u0441\u0442\u043d\u043e\u0439 \u0438\u043d\u0444\u043e\u0440\u043c\u0430\u0446\u0438\u0438 \u043f\u043e\u043b\u044c\u0437\u043e\u0432\u0430\u0442\u0435\u043b\u0435\u0439, \u0432 \u0442\u043e\u043c \u0447\u0438\u0441\u043b\u0435 \u0438\u0441\u043a\u043b\u044e\u0447\u0438\u0442\u044c \u0432\u043e\u0437\u043c\u043e\u0436\u043d\u044b\u0435 \u0437\u043b\u043e\u0443\u043f\u043e\u0442\u0440\u0435\u0431\u043b\u0435\u043d\u0438\u044f \u0441\u043e \u0441\u0442\u043e\u0440\u043e\u043d\u044b \u0441\u043f\u0435\u0446\u0441\u043b\u0443\u0436\u0431 \u0438 \u0430\u0434\u043c\u0438\u043d\u0438\u0441\u0442\u0440\u0430\u0442\u043e\u0440\u043e\u0432, \u0438\u043c\u0435\u044e\u0449\u0438\u0445 \u0434\u043e\u0441\u0442\u0443\u043f \u043a \u0443\u0437\u043b\u0430\u043c \u0441\u0435\u0442\u0438.
