Xmark empowers you to take control of your X/Twitter content. This browser extension records your posts on the Bitmark blockchain, ensuring ownership and protecting your content from censorship. It also shares your content with the decentralized Nostr network.
Xmark runs silently in the background, keeping your browsing experience smooth. All your X/Twitter posts, including images and videos, are securely stored on our servers. You can easily download them anytime using a unique code. For ultimate security, Xmark also stores a verified record of your post's content on the blockchain, ensuring you always own and control your creations.
Once you post on X/Twitter, Xmark quickly records your content on the Bitmark blockchain within a few minutes. You can then easily verify your ownership by viewing the transaction details and associated hash in a Bitmark block explorer. Additionally, your post will also be shared on the Nostr network. Linkmark, a related project that defines the marking protocol, allows you to search for marked data using keywords or hashes, making it easy to find and explore content across the decentralized web.
