Blockchain registry scaling

A system, comprising:

• one or more processors configured to:
• receive a request to perform an action for a domain of a name service, wherein the name service is implemented using at least a first blockchain network and a second blockchain network different from the first blockchain network;
• determine whether the domain is managed on the first blockchain network or the second blockchain network including by using a domain registry of the second blockchain network, wherein the domain registry of the second blockchain network tracks a first group of domains managed on the first blockchain network and a second group of domains managed on the second blockchain network;
• and
• cause the action for the domain to be performed based on the determination of whether the domain is managed on the first blockchain network or the second blockchain network;
• and
• a memory coupled to at least one of the one or more processors and configured to provide at least one of the one or more processors with instructions.

A computer program product embodied in a non-transitory computer readable medium and comprising computer instructions for:

• receiving a request to perform an action for a domain of a name service, wherein the name service is implemented using at least a first blockchain network and a second blockchain network different from the first blockchain network;
• determining whether the domain is managed on the first blockchain network or the second blockchain network including by using a domain registry of the second blockchain network, wherein the domain registry of the second blockchain network tracks a first group of domains managed on the first blockchain network and a second group of domains managed on the second blockchain network;
• and
• causing the action for the domain to be performed based on the determination of whether the domain is managed on the first blockchain network or the second blockchain network.
