 It does because scale is very much about the peer-to-peer exchange. I said that we maintain basically this basic relationship. I'm a manufacturer of my clients or my suppliers and they exchange proofs and sort of cryptographic proofs and verifiable credentials. So we maintain this and it's a peer-to-peer. The underlying blockchain level is for the public keys. That must be looked up for verification. The schemas that are only issued once in a while so the schemas never change really. Maybe once a while a certifier extends a schema. But it anyway has to be based on common understanding, how the greenhouse gas protocol or the ISO standards or maybe extensions on top of this would define the attributes in the verifiable credentials. So it's scale I don't see really as an issue. No, I just guess. We hash blocks of data to the blockchain with the vast majority. And we've got hundreds of millions of records coming in from the supply chain that would just create indigestion. So we're using traditional databases, Oracle and graph databases, to store a lot of the heavy data and then hashing packets that data to the blockchain. And a similar approach really to gaining the benefit of the distributed ledger without the disadvantages of trying to store vast quantities of information in the distributed ledger itself.
