Storing and distributing large data sets is still challenging. There are issues like corrupted files, bandwidth limitations or just unreliable networks. This talk is an introduction into peer-to-peer technologies and [IPFS]. You will learn how these technologies can help you with the previously mentioned problems and why it is a great fit for your geodata. Such a peer-to-peer network doesn't necessarily need to be a public one, everyone can participate in, it may also be used to distribute the data between trusted parties. Currently, there is a Go and a JavaScript implementation — that even runs in the Browser — of IPFS available. IPFS is fully open source and licensed under the MIT Licence (soon MIT+Apache2 dual licence). [IPFS]: https://ipfs.io/
