IPFS - The Permanent Web - at Sourcegraph

High-level presentation of IPFS at Sourcegraph meetup #003.

IPFS is a global, versioned, peer-to-peer file system. It combines good ideas from Git, BitTorrent, Kademlia, and SFS. You can think of it like a single BitTorrent swarm, exchanging Git objects, making up the web. IPFS provides an interface much simpler than HTTP, but has permanence built in. You can also use it to mount the world at `/ipfs`.

1. IPFS The Permanent Web
4. IPFS background overview use cases future
5. it all starts simple
6. dataset package manager
7. dataset package manager needed git + bittorrent
8. dataset package manager needed git + bittorrent suddenly, everything made sense
9. dataset package manager needed git + bittorrent suddenly, everything made sense
10. IPFS content addressed versioned peer-to-peer filesystem
11. IPFS goal - to connect all devices with the same system of files
12. IPFS goal - to connect all devices with the same system of files like the web plus git and bittorrent
13. IPFS = DHT + BT + Git + SFS + Web
14. IPFS = DHT + BT + Git + SFS + Web

57. IPFS background overview use cases future
58. 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).
59. 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.
