Mirror
Mirror is a web3 publishing platform that empowers creators to publish, share, and monetize their work using blockchain technology. By connecting an Ethereum wallet, users can publish content stored on decentralized networks like Arweave, ensuring permanence and censorship resistance. Mirror offers features such as Writing NFTs, enabling authors to mint their writing as digital collectibles, and web3 subscriptions, allowing readers to subscribe with their wallets and receive updates directly. The platform also supports collaborative projects, making it suitable for DAOs and multisig groups. In May 2024, Mirror joined forces with Paragraph, with Paragraph taking over stewardship of the Mirror product, design system, and brand, marking a significant milestone in onchain publishing.

Arweave
Arweave is a new type of storage that backs data with sustainable and perpetual endowments, allowing users and developers to truly store data forever, for the very first time. As a collectively owned hard drive that never forgets, Arweave allows us to remember and preserve valuable information, apps, and history indefinitely. By preserving history, it prevents others from rewriting it. On top of the Arweave network lives the permaweb, a global, community-owned web that anyone can contribute to or get paid to maintain. The permaweb looks just like the normal web, but all of its content, from images to full web apps, is permanent, retrieved quickly, and decentralized, forever. Just as the first web connected people over vast distances, the permaweb connects people over extremely long periods of time. No more 404s, no more stealth edits, and no more web apps that decline in quality.

Chainpoint
Anchor an unlimited amount of data to the Bitcoin blockchain. Verify the integrity and existence of data without relying on a trusted third-party. Chainpoint links a hash of your data to a blockchain and returns a timestamp proof. A Chainpoint Node receives hashes which are aggregated together using a Merkle tree. The root of this tree is published in a Bitcoin transaction. The final Chainpoint proof defines a set of operations that cryptographically link your data to the Bitcoin blockchain. A Chainpoint proof contains the information to verify that the hash of some data is anchored to a blockchain. It proves the data existed at time it was anchored. Chainpoint proofs can be verified without reliance on a trusted third party.

Blocknotary
Blockchain enabled timestamps for media files. Proof of ownership, proof of integrity, and proof of existence on mobile devices. BlockNotary Timestamp notarizes any media file, generating publicly verifiable receipt of its origin, date, authenticity, and integrity, without exposing its contents. Its uses include digital attribution, proof of existence, prior knowledge, integrity, and authenticity. Timestamp creates 100% distributed proofs using OTS (OpenTimestamps), IPFS (InterPlanetary File System) and public Bitcoin or Ethereum blockchains. Generated receipts are independently verifiable and machine-readable. Upload a media file to the app and securely store it in a distributed file system that is protected by the blockchain.
