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.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Open Source Surface applies to this provider. This product is open source and we read its repository directly, so Open Source Surface carries 10 points of the composite. It is scored from what the repository actually publishes — a security policy, a contribution guide, a release history, a code of conduct — read live from the provider rather than inferred from our own catalog pointers. This facet adds; nothing was taken away to make room for it. An open-source project is not excused from the commercial facets, because exemption would strip it of the points it does earn. If we have the wrong repository, or this product is not open source, say so on your provider repo and we will drop the facet rather than have you publish against it.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 75 points between them, because both conditional facets apply and carry 25 points together. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/capsule-social: open an issue to ask a question, or submit a pull request to add artifacts.
