<p>There are many p2p application. One prominent one is Bittorrent (<a href="https://en.m.wikipedia.org/wiki/BitTorrent" rel="nofollow noreferrer">https://en.m.wikipedia.org/wiki/BitTorrent</a>) which allows users to store, distribute and download files from peers. Bittorrent at some point made up more than half of the internet‘s traffic.
Skype also used to be a P2P application but has since switched to a server based model. </p>

<p>Are there any p2p decentralised cross border network structure out there? </p>

<blockchain>
Is blockchain the only technology for p2p decentralised global network?
