Iroh is a relatively new distributed file storage and content delivery system that’s designed as an evolution of existing decentralized systems like IPFS (InterPlanetary File System). Both Iroh and IPFS can be used to create decentralized networks for storing, sharing and accessing content addressed using opaque content identifiers. However, Iroh removes some of the limitations of IPFS implementations such as having no maximum block size and providing a syncing mechanism for data via range-based set reconciliation over documents. The project's roadmap includes bringing the technology to the browser via WASM, which raises some intriguing possibilities for building decentralization into web applications. If you don't want to host your own Iroh nodes, you can use its cloud service, iroh.network. There are already several SDKs available in a variety of languages, and one goal is to be more user-friendly and easier to use than alternative IPFS systems. Even though Iroh is still in its very early days, it's worth keeping an eye on it, as it could become a significant player in the decentralized storage space.
