 There is an existing [IPFS devgrant](https://github.com/ipfs/devgrants) to host [OpenStreetMaps assets on IPFS](https://github.com/ipfs/devgrants/blob/8233f7df4a219122bcf31eaea289d654406e4443/targeted-grants/open-street-map-ipfs.md). In the long run, this could mean faster synchronization for apps using this scheme and lower bandwidth requirements for servers.

 ### Help host important data
 
 Thanks to recent improvements with IPFS Cluster, you can call for help to store your data without having to trust other nodes won't alter the data. With [collaborative mode](https://ipfscluster.io/documentation/collaborative), you can [replicate Pacman packages or COVID-19-related papers](https://collab.ipfscluster.io/) without needing to know the intricacies of IPFS.

+[NIIIFTY](https://niiifty.com) is a platform built using [web3.storage](#decentralized-storage) that simplifies the sharing of [IIIF-formatted](https://iiif.io) high-resolution images, 3D models, and audiovisual content via IPFS. View the [documentation](https://niiifty.com/docs) for how to set up your own NIIIFTY instance.

 ## IPFS as infrastructure
 
 Using IPFS allows you to abstract away a lot of the complexity of coordination between machines. No matter your architecture IPFS handles load balancing, de-duplication, caching, and high availability out-of-the-box. It's highly modular design also means you can easily customize it to your need.

Actyx built a custom operating system on top of IPFS they deploy on all machines, so they emit metrics, receive orders, sync up information, and compute their next move locally.
 
+### Decentralized storage
+
+The [web3.storage](https://web3.storage) platform provides an IPFS-based storage service to safely secure and make your data available - giving developers the power of decentralized storage and content addressing via simple client libraries or an HTTP API.

 ## Lower your storage usage
 
 By storing identical data only once on your node, storage-constrained projects are another natural fit for IPFS.

 [Decentralized Identity](https://en.wikipedia.org/wiki/Decentralized_Identifiers) is the concept of storing all your personal data on your devices rather than let every service you use store a partial copy of it. You having control of your data means that you decide which app has access to what, that you only fill in your information once, and that you can revoke access. Decentralized identity is a hot topic, and IPFS is one of the core technologies a lot of engineers build around. The identity wallet [Nomios](https://nomios.io/) shared [some thoughts](https://docs.google.com/presentation/d/1HbydOI0w-T_FY23zCACAyHmzDq1ZvyG2tklpPSm6OQQ/edit#slide=id.g5c88e8f60d_0_11) about decentralized identity general during the [IPFS Camp 2019](https://github.com/ipfs/camp).
