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 in a decentralized manner, 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 storage network, allows users to store, request, and transfer data via a verifiable marketplace. Filecoin is an entirely open-source alternative to costly cloud storage, where a blockchain network offers efficiently priced and geographically decentralized storage that ensures the persistence of user’s data.

If you would like to get started now and learn about the key concepts behind IPFS and Filecoin, please check our Resources page here. We prepared this content to help you build with them, including developer tools that help you store data on both IPFS and Filecoin quickly and easily.

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.

MakerDAO is an open-source project on the Ethereum blockchain and a Decentralized Autonomous Organization1 created in 2014. The project is managed by people around the world who hold its governance token, MKR. Through a system of scientific governance involving Executive Voting and Governance Polling, MKR holders manage the Maker Protocol and the financial risks of Dai to ensure its stability, transparency, and efficiency. MKR voting weight is proportional to the amount of MKR a voter stakes in the voting contract, DSChief. In other words, the more MKR tokens locked in the contract, the greater the voter’s decision-making power.
