Blockchain registry scaling

A method, comprising:

• receiving a request to migrate a domain of a name service from a first blockchain network to a second blockchain network, wherein the name service is implemented using at least both the first blockchain network and the second blockchain network different from the first blockchain network, and wherein the domain is minted on the first blockchain network;
• retrieving, from a domain entry of a registry of the first blockchain network, a domain name identifier, a domain owner identifier, and records of the domain;
• creating a storage domain entry for the domain on the second blockchain network, wherein the created storage domain entry includes a domain name field, a storage entry owner field, and one or more record fields;
• and
• updating the created storage domain entry including by:
• setting the domain name field to the retrieved domain name identifier, setting the storage entry owner field to the retrieved domain owner identifier, and setting contents of the one or more record fields to contents of the retrieved records of the domain.

A system, comprising:

• a communication interface configured to receive a request to perform a management action for a domain managed on a first blockchain network or a second blockchain network;
• and
• one or more processors configured to cause the management action for the domain to be performed;
• wherein a layer-1 registry smart contract is implemented on the first blockchain network and the layer-1 registry smart contract is configured to track a first group of domains minted on the first blockchain network, and a layer-2 registry smart contract is implemented on the second blockchain network and the layer-2 registry smart contract is configured to track a second group of domains minted on the first blockchain network and the second blockchain network.
