The next peer-to-peer protocol

Introduction

BitTorrent is, of course, the world's most used peer to peer protocol. It's great, but it was designed before the cloud was ubiquitous and it doesn't make use of the places where you have the most storage or the most bandwidth. Can we design something for the next decade?

BitTorrent is based on the concept of peers, which are BitTorrent clients, usually running on computers at home, that share data is a super-efficient manner. It works well, of course, but

There are of course alternatives (you can rent servers in data centers for example), but they are not cheap, they're not easy to set up, and they come with their own sets of problems, in general.

These days most people have lots of their data in the cloud: Dropbox, Google Drive and so on.

Your job

The goal here is to come up (and implement the first version) with a system that let those personal storage systems exchange data

A possible idea (one of many possibilities) would be to introduce the concept for "agent". An agent would be a process that runs in the cloud on behalf of the user and that has access to his personal storage accounts. The agents can run anywhere, but their ideal place is the cloud, for example, AWS or Google Cloud. They can be managed by the final user or by a 3rd party that provides the service.

Agents find each other, and learn to trust each other, with the help of repositories, the equivalent of today's trackers.

Agents that trust each other can vouch for other agents.

The chain of trust must always be preserved so agents can prune trees if the trust is broken.
