Abstract

A gateway interfacing with multiple distributed ledger networks may receive, from a buyer on a first distributed ledger network, a request to purchase an asset in exchange for a cash token, the asset being sold by a seller on a second distributed ledger network and an entry on the second distributed ledger network, and the cash token is an entry on the first distributed ledger network; communicate the request to the seller; receive acceptance of the request from the seller; transfer the asset to an electronic wallet for the buyer by updating ownership of the asset on the second distributed ledger network and on the first distributed ledger network; and transfer the cash token to an electronic wallet for the seller by updating ownership of the cash token on the second distributed ledger network and on the first distributed ledger network.

First claim

What is claimed is:

1. A method for cross-ecosystem aggregation of assets using distributed ledgers, comprising:
receiving, at a gateway in communication with a plurality of distributed ledger networks and an asset marketplace, a notification from a seller of an energy credit asset that is available for purchase on a first distributed ledger network of the plurality of distributed ledger networks written as an energy credit asset token in a seller electronic wallet on the first distributed ledger network that is specific to the first distributed ledger network;
making, by the gateway, the energy credit asset available for purchase on the asset marketplace;
receiving, from the asset marketplace, a purchase of the energy credit asset by a buyer participating on a second distributed ledger network of the plurality of distributed ledger networks, the purchase comprising a cash token from a buyer electronic wallet on the second distributed ledger network that is specific to the second distributed ledger network;
verifying, by the buyer, that the energy credit asset token is active by confirming that the energy credit asset token is on a list of active energy credit asset tokens;
validating, by the seller, the cash token by checking a digital signature on the cash token;
verifying, by the seller, that the cash token is active by confirming that the cash token is on a list of active cash tokens;
communicating, by the gateway, the purchase to the first distributed ledger network in response to the verification that the energy credit asset token is verified as active, the validation of the cash token, and the verification that the cash token is active;
transferring, by the gateway, the energy credit asset token from the electronic wallet for the seller to the electronic wallet for the buyer by updating ownership of the energy credit asset token on both the second distributed ledger network and on the first distributed ledger network; and
transferring, by the gateway, the cash token from the electronic wallet for the buyer to the electronic wallet for the seller by updating ownership of the cash token on both the second distributed ledger network and on the first distributed ledger network.

2. The method of claim 1 , wherein the energy credit asset token is digitally signed by the first distributed ledger network.

3. The method of claim 1 , wherein the cash token is digitally signed by the second distributed ledger network.

4. The method of claim 1 , further comprising:
redeeming, by the first distributed ledger network, the cash token for fiat currency.

5. The method of claim 1 , wherein the energy credit asset comprises a renewable energy credit asset.

6. A system for cross-ecosystem aggregation of assets using distributed ledgers, comprising:
a first distributed ledger network;
a second distributed ledger network;
an asset marketplace; and
a gateway communicating with the first distributed ledger network, the second distributed ledger network, and the marketplace;
wherein:
the gateway receives a notification from a seller of an energy credit asset that is available for purchase on the first distributed ledger network written as an energy credit asset token in a seller electronic wallet on the first distributed ledger network that is specific to the first distributed ledger network;
the gateway makes the energy credit asset available for purchase on the asset marketplace;
the gateway receives, from the asset marketplace, a purchase of the energy credit asset by a buyer participating on the second distributed ledger network, the purchase comprising a cash token from a buyer electronic wallet on the second distributed ledger network that is specific to the second distributed ledger network;
the buyer verifies that the energy credit asset token is active by confirming that the energy credit asset token is on a list of active energy credit asset tokens;
the seller validates the cash token by checking a digital signature on the cash token;
the seller verifies that the cash token is active by confirming that the cash token is on a list of active cash tokens;
the gateway communicates the purchase to the first distributed ledger network in response to the verification that the energy credit asset token is verified as active, the validation of the cash token, and the verification that the cash token is active;
the gateway transfers the energy credit asset token from the electronic wallet for the seller to the electronic wallet for the buyer by updating ownership of the energy credit asset token on both the second distributed ledger network and on the first distributed ledger network; and
the gateway transfers the cash token from the electronic wallet for the buyer to the electronic wallet for the seller by updating ownership of the cash token on both the second distributed ledger network and on the first distributed ledger network.

7. The system of claim 6 , wherein the energy credit asset token is signed by the first distributed ledger network.

8. The system of claim 6 , wherein the cash token is signed by the second distributed ledger network.

9. The system of claim 6 , further wherein the first distributed ledger network redeems the cash token for fiat currency.

10. The system of claim 6 , wherein the energy credit asset comprises a renewable energy credit asset.

11. A non-transitory computer readable storage medium, including instructions stored thereon, which when read and executed by one or more computer processors, cause the one or more computer processors to perform steps comprising:
receiving a notification from a seller of an energy credit asset that is available for purchase on a first distributed ledger network of a plurality of distributed ledger networks written as an energy credit asset token in a seller electronic wallet on the first distributed ledger network that is specific to the first distributed ledger network;
making the energy credit asset available for purchase on an asset marketplace;
receiving a purchase of the energy credit asset from the asset marketplace by a buyer participating on a second distributed ledger network of the plurality of distributed ledger networks, the purchase comprising a cash token from a buyer electronic wallet on the second distributed ledger network that is specific to the second distributed ledger network;
receiving verification from the buyer that the energy credit asset token is active based on the energy credit asset token being on a list of active energy credit asset tokens;
receiving validation from the seller that the cash token is valid based on a digital signature on the cash token;
receiving verification from the seller that the cash token is active based on the cash token being on a list of active cash tokens;
communicating the purchase to the first distributed ledger network in response to the verification that the energy credit asset token is verified as active, the validation of the cash token, and the verification that the cash token is active;
transferring the energy credit asset token from the electronic wallet for the seller to the electronic wallet for the buyer by updating ownership of the energy credit asset token on both the second distributed ledger network and on the first distributed ledger network; and
transferring the cash token from the electronic wallet for the buyer to the electronic wallet for the seller by updating ownership of the cash token on both the second distributed ledger network and on the first distributed ledger network.

12. The non-transitory computer readable storage medium of claim 11 , wherein the energy credit asset token is signed by the first distributed l
