Is it basically to solve the issue of a large amount of data on bitcoins using a hybrid PoW and PoP system? Keep an eye on this project.
That's one aspect of the project; by creating a 'tree-of-chains' structure, VeriBlock + PoP enable a large ecosystem of blockchains to proliferate because they can operate with a similar security context as Bitcoin, while 'paying' Bitcoin and its miners for the privilege.
