IPFS is a peer-to-peer network and protocol designed to make the web faster, safer, and more open. IPFS upgrades the web to work peer to peer, addressing data by what it is instead of where it’s located on the network, or who is hosting it.

Filecoin - the world’s largest decentralized network, allows users to store, request, and transfer data via a verifiable marketplace. Filecoin is completely open-source, enabling people from all over the world to participate. The Filecoin protocol runs on an advanced and novel proof system — a combination of Proof of Spacetime (PoSt) and Proof of Replication (PoRep), to provide unmatched efficiency and reliability. Filecoin’s advanced technology provides a robust foundation to store the world’s most valuable data sets. An alternative to costly cloud storage, the Filecoin network offers efficiently priced and geographically decentralized storage, minimizing financial barriers, and allowing users to take advantage of its unmatched network capabilities.

The Graph is an indexing protocol for organising and efficiently accessing data from blockchains and storage networks. The Graph has been running a hosted service since January 2019 with over 2,300 subgraphs deployed for Web3 and DeFi applications built on Ethereum and IPFS, like Synthetix, Uniswap, Aave, Balancer, Gnosis, Aragon, and more.

Superfluid is an asset streaming protocol that enables subscriptions, salaries and rewards to DAOs and crypto-native businesses. It can be used to describe cash flows and execute them automatically on-chain over time in a non-interactive way. Superfluid streams are programmable, composable and modular. The first cash flow types allow constant streams of value and one-to-many distributions. All streams are settled at the same time, based on block timestamps. No capital is locked up, and all inflows and outflows are netted in real time, drastically increasing capital efficiency. A curated suite of developer tools is available, ranging from extensive documentation on the smart contract framework, to SDKs for easy integration (Solidity, Typescript, Redux), to a developer Console to query all needed data during testing and debugging.

Unlock is an open source, Ethereum-based protocol designed to streamline membership benefits for online communities. Unlock is meant to help creators find ways to monetize or manage membership without relying on a middleman. It’s a protocol — and not a centralized platform that controls everything that happens on it.Unlock’s mission is about taking back subscription and access from the domain of middlemen — from a million tiny silos and a handful of gigantic ones — and transforming it into a fundamental business model for the web.The Unlock Protocol can be applied to DAO tooling (e.g. token gating) content locking (paywalls), newsletters, software licenses or even the physical world, such as NFT ticketing.
