Chinese online retailer Alibaba filed a patent application on 15 August entitled “Domain Name Management Scheme for Cross-Chain Interactions in Blockchain Systems”. Alibaba plans to use a blockchain system that uses a “Unified Blockchain Domain Name” (UBCDN) to identify and share information.

The system should generate a UBCDN message containing a blockchain domain name and a chain identifier. The domain name and the chain identifier are linked. In addition, the UBCDN message should contain a UBCDN of the blockchain instance, a digital signature of the UBCDN owner of the blockchain instance and a UBCDN certificate.

It also states in the Alibaba patent application that the system serves as a medium for managing domain names in the interaction of various blockchain systems. In addition, the system includes an identifier or label that helps users reach the appropriate blockchain instance. Thus block chain operators can select the blockchain domain name according to their company name. This allows users to infer the corresponding identifiers and promotes the use of the blockchain.

In addition, the UBCDN may include a human readable identifier or label that helps users to easily remember and reach a blockchain instance, thus promoting the inheritance or use of the blockchain instance.

Alibaba also sees an improvement over existing interoperable blockchain networks:

Unlike existing cross-chain implementations such as COSMOS, where each blockchain is assigned an ID identifier within the relay network, the ID identifier can only cover a local extent and can not be reused in other relay networks. The UBCDN can be used in the described domain naming scheme and is globally identifiable by all blockchain instances in the “Unified Blockchain Network”.
