(Gentle music) So the power of these distributed ledgers, so just a recap it can be used without a central authority okay, because it's distributed. Everybody every entity has whole truth, holds the same access to the data. It's not that I have to go to a bank to be 100% that my data is correct, my ledger is correct. Everybody has the same access. It can be used to transfer value, so there are some consensus mechanism that we know that there is consensus in terms of the data which we hold, and it can be used to record that. So instead of recording in into my own database which is recorded over a peer group of databases of servers in the market. So if one database or one server gets out the data is not lost, it's still with other store with other servers and then it can be used to allow owners of assets to exercise certain rights and exercise his rights. So basically this is which we discussed before the perfection of the interest or basically if I buy a receivables, how do I know that I own something? If you have if you don't have blockchain you had to say okay who has a record. Tell me why you own it, yeah because I have a legal agreement, I have a paper. With distributed ledger technology the theory is that a somewhere this first transaction the transaction between the supplier and the buyer when the supplier sells are good to a buyer and suddenly has a receivable. This is stored already on the blockchain. I don't have to prove based on the paper that I own is receivable. So by buying this receivables from the supplier this data is changed on the blockchain is updated and I can use that as a proof that I owe now that I'm the owner of this receivable.
