You are describing IPFS. If you install IPFS, then browse to some IPFS content (like a wikipedia mirror: ipns://en.wikipedia-on-ipfs.org/wiki/), that’s cached on your system, if someone else requests those assets, your computer will help distribute it. You can “pin” content, keeping/seeding a copy.
