Capsule Social

Capsule Social was a decentralized-innovation company founded in early 2021 by cryptography researcher Nadim Kobeissi to build tools for a web3 future. Its flagship product, Blogchain, was a decentralized publishing and social platform — a Substack-like blogging experience with Twitter-like social elements — built on IPFS for serverless content storage and the NEAR Protocol for identity, digital-asset management, and tokenized community governance, letting creators own their content and monetize it behind optional paywalls. The company raised a ~$2.6M seed round from investors including Polychain, Naval Ravikant, Fyrfly, and former Coinbase CTO Balaji Srinivasan. The Blogchain product and the capsulesocial GitHub organization have been inactive since roughly October 2023, and the capsule.social domain has since been re-registered by an unrelated "social memory" consumer app — so the surviving authoritative surface for this entity is its open-source GitHub org, not the current website. There is no hosted REST API: Blogchain is a client-side web3 dApp (Vue frontend, NEAR smart contracts, IPFS).

Capsule Social is profiled on the APIs.io network. Tagged areas include Company, Social, Web3, Blockchain, and Decentralized.
