53    <h3 class="faq-question">Is your code open source?</h3>
54    <p class="faq-answer">
55      Everything, including this website, is open source <a

62    <h3 class="faq-question">How does the blind signature authentication work?</h3>
63    <p class="faq-answer">
64      When connecting, users present a cryptographic proof of valid Plus or Free subscription

65      rather than identifying credentials. This ensures servers can verify authorization while
66      remaining completely blind to user identity. Learn more about the protocol <a

72  <div class="faq-item">
73    <h3 class="faq-question">Can’t the censor just download Geph and block all the servers?</h3>
74    <p class="faq-answer">
75      Yes and no &mdash; Geph uses a two-hop architecture where users connect to <em>exit</em>
76      nodes through <em>bridge</em> relays. Censors can and do block all the exit servers, but blocking
77      bridges is much harder.
78    </p>
79    <p class="faq-answer">
80      This is because a hard-to-block bootstrap protocol assigns <em
81        >different bridges to different users</em
82      >
83      and continuously rotates them, making enumeration infeasible. Since 2019, we've observed automated
84      enumeration attempts by China’s GFW, but they have consistently failed to disrupt service.

92    <h3 class="faq-question">Isn’t this centralized?</h3>
93    <p class="faq-answer">
94      Yes, but not for long! We are actively developing integration with <a
95        href="https://earendil.network">Earendil</a
96      > by achieving full protocol decentralization. This will completely eliminate our infrastructure
97      as a central point of failure.

102    <h3 class="faq-question">How is Geph funded?</h3>
103    <p class="faq-answer">
104      Geph is <em>entirely community-funded through Plus subscriptions</em>, ensuring our long-term independence and sustainability.
