Didn't look very long, so I may be missing something. Nonetheless, that's not a blockchain. That's IBM hijacking the word to turn a profit.
It's a blockchain as long as you trust IBM, which means it's not a blockchain. Can anyone in the world download a quick program, start their own node, and download the entire blockchain to their computer ensuring immutability across the entire network since there's hundreds of thousands of copies of it floating around? Didn't think so, hence it's not a blockchain.
Again, I may be missing something, but doubt it.
