# INFRASTRUCTURE

Infrastructure smart contracts are used to build the underlying infrastructure for Web3, such as decentralized storage and computing platforms.

* **Storage:** These contracts provide decentralized storage solutions for data and applications. Examples include Arweave, Filecoin, and Siacoin.
* **Computing:** These contracts provide decentralized computing power for running applications and processing data. Examples include Golem, Akash, and Render Network.
* **Networking:** These contracts provide a decentralized networking infrastructure for connecting devices and applications. Examples include IPFS, Swarm, and Livepeer.
* **Identity:** These contracts provide decentralized identity management solutions for users and applications. Examples include DIDKit, uPort, and Sovrin.
* **Payments:** These contracts provide decentralized payment solutions for users and applications. Examples include Lightning Network, xDai, and Polygon.
