IPFS background overview use cases future

Slide 58

Slide 58 text

use cases 1. As a mounted global filesystem, under /ipfs and /ipns. 2. As a mounted personal sync folder that automatically versions, publishes, and backs up any writes. 3. As an encrypted file or data sharing system. 4. As a versioned package manager for all software. 5. As the root filesystem of a Virtual Machine. 6. As the boot filesystem of a VM (under a hypervisor).

Slide 59

Slide 59 text

use cases 7. As a database: applications can write directly to the Merkle DAG data model and get all the versioning, caching, and distribution IPFS provides. 8. As a linked (and encrypted) communications platform. 9. As an integrity checked CDN for large ﬁles (without SSL). 10. As an encrypted CDN. 11. On webpages, as a web CDN. 12. As a new Permanent Web where links do not die.
