US 2021/0176074 A1 · DOMAIN NAME MANAGEMENT SCHEME FOR CROSS-CHAIN INTERACTIONS IN BLOCKCHAIN SYSTEMS

Abstract

Implementations of the present disclosure include obtaining, from a trusted certificate authority (CA) by an owner of a unified blockchain domain name (UBCDN) of a blockchain instance (a UBCDN owner) in a unified blockchain network, a domain certificate of the UBCDN of the blockchain instance; signing the UBCDN of the blockchain instance; and publishing a UBCDN message of the blockchain instance. The UBCDN of the blockchain instance includes a blockchain domain name and a chain identifier of the blockchain instance. The domain certificate of the UBCDN includes the blockchain domain name, a public key of the UBCDN owner, and a digital signature of the CA on the blockchain domain name and the public key of the UBCDN owner. The UBCDN message includes the UBCDN, a digital signature of the UBCDN owner resulting from the signing the UBCDN, and the domain certificate of the UBCDN.

A computer-implemented method comprising:

obtaining, by a client node of a first blockchain instance, a blockchain domain name of a second blockchain instance in a unified blockchain network, wherein the unified blockchain network comprises a plurality of blockchain instances that are communicatively linked by two or more relays, the plurality of blockchain instances comprise the first blockchain instance and the second blockchain instance, and each of the plurality of blockchain instances comprises an implementation of a blockchain based on a respective blockchain platform or technology, wherein:
the blockchain domain name is a unique identifier of the second blockchain instance in the unified blockchain network, wherein the blockchain domain name of the second blockchain instance is recognizable globally by all the plurality of blockchain instances and the two or more relays in the unified blockchain network;
the blockchain domain name comprises a human-readable label;
and
the blockchain domain name uniquely corresponds to a chain identifier of the second blockchain instance, wherein the chain identifier of the second blockchain instance indicates a blockchain network configuration of the second blockchain instance and allows access to the second blockchain instance based on the blockchain network configuration;
identifying, by the client node, the chain identifier of the second blockchain instance based on the blockchain domain name of the second blockchain instance;
and
accessing, by the client node, the second blockchain instance based on the blockchain network configuration indicated by the chain identifier of the second blockchain instance.
