Just insert your Nostr private key and start posting.</p><p><a href="https://nostr.com/" target="_blank" rel="noindex nofollow noopener">Nostr</a> is an open protocol that is able to create a censorship-resistant global "social" network, transferring notes and other stuff using relays. It doesn't rely on any trusted central server, hence it is resilient; it is based on cryptographic keys and signatures, so it is tamperproof; it does not rely on P2P techniques, therefore it works.</p><p><b>What you can do with Amethyst</b></p><ul><li>Post text, photos, videos, long-form articles, polls and voice notes to the relays you choose.</li><li>Follow people, reply, repost, react and quote.</li><li>Send private, end-to-end encrypted direct messages and join group chats.</li><li>Browse dedicated feeds: articles, pictures, short videos, live streams, podcasts, music, communities, classifieds, calendars and more.</li><li>Send and receive Bitcoin Lightning zaps.</li><li>Track your training and share a workout — see below.</li></ul><p><b>My Fitness — track your training</b></p><p>Amethyst includes a personal training dashboard.
