Domain name management scheme for cross-chain interaction of blockchain

Domain name management scheme for cross-chain interaction of blockchain

Main content

Different blockchain platforms and technologies have led to the fragmentation of blockchain networks.

Existing blockchain access methods require complex network configuration and are not user-friendly.

The UBDCN scheme provides a unified, human-readable identifier for each blockchain instance.

The UBDCN scheme simplifies the identification and addressing protocol for cross-chain interactions.

The UBDCN scheme enhances trust and security through certificate authorities (CA) and public key infrastructure (PKI).

Short answer questions

What are the problems with existing blockchain network access methods?

Answer: Existing blockchain network access methods require users to configure complex network parameters, such as hash values, member certificates, etc. These parameters are difficult for humans to understand and remember, which increases the difficulty for users to use blockchain.

What is UBCDN? What problem does it solve?

Answer: The Unified Blockchain Domain Name (UBCDN) is a globally unique identifier provided for each blockchain instance. It binds the human-readable domain name with the network configuration information of the blockchain instance, solving the problem that the existing blockchain access method is complex and user-unfriendly.

What are the components of UBCDN?

A: UBDCN consists of two parts: blockchain domain name and chain identifier. The blockchain domain name is a human-readable identifier, while the chain identifier contains the network configuration information of the blockchain instance.

How does UBCDN simplify cross-chain interactions?

A: UBDCN provides a unified identifier for all blockchain instances, regardless of the platform or technology they are based on. Nodes can use UBDCN to directly identify and access the target blockchain instance without having to understand complex network configuration information, thereby simplifying cross-chain interactions.

How does UBCDN enhance the trust and security of cross-chain interactions?

A: The UBDCN scheme enhances trust and security through certificate authorities (CA) and public key infrastructure (PKI). CA is responsible for issuing digital certificates to UBDCN owners to verify their ownership of blockchain domain names.

What are the advantages of UBCDN?

A: The advantages of UBDCN include: easy to remember and identify, simplified cross-chain interactions, enhanced trust and security, and support for updates to blockchain network configurations.

In the UBCDN scheme, how does the client node access the target blockchain instance?

A: The client node first queries its chain identifier based on the blockchain domain name of the target blockchain instance. The client node then uses the network configuration information contained in the chain identifier to connect to the target blockchain instance.

What is the role of the relay node in the UBCDN solution?

Answer: The relay node is responsible for connecting different blockchain instances and parsing the network configuration information of the target blockchain instance according to UBDCN to help the client node complete cross-chain interaction.

If the network configuration information of the blockchain instance changes, how does the UBCDN solution handle it?

Answer: When the network configuration information of the blockchain instance changes, the UBCDN owner can update the chain identifier in UBDCN, while the blockchain domain name remains unchanged. Other nodes can continue to access the blockchain instance using the updated UBDCN.

What are the advantages of the UBCDN solution compared to existing cross-chain solutions such as COSMOS?

Answer: Compared with existing cross-chain solutions such as COSMOS, the advantages of the UBCDN solution are: UBCDN is a globally unique identifier, while the identifier in COSMOS is only valid in a specific relay chain network; UBCDN is more human-friendly and easy to remember and identify.

Key Glossary

Term Definition Blockchain instance An instance of a blockchain network implemented and deployed based on a specific blockchain platform or technology. Cross-chain interaction The process of data exchange and communication between different blockchain instances. Unified Blockchain Domain Name (UBCDN) A globally unique identifier provided for each blockchain instance, consisting of a human-readable blockchain domain name and a chain identifier. The human-readable part of the blockchain domain name UBDCN is used to identify the blockchain instance. The chain identifier The part of the UBDCN that contains the network configuration information of the blockchain instance, which is used to connect and access the blockchain instance. Certificate Authority (CA) An institution responsible for issuing and managing digital certificates, which is used to verify the ownership of blockchain domain names by UBDCN owners. Relay nodes connect nodes of different blockchain instances, are responsible for parsing UBDCN and helping client nodes complete cross-chain interactions. Blockchain network configuration is used to connect and access network parameters of blockchain instances, such as IP address, port number, genesis block hash value, etc. Public Key Infrastructure (PKI) A set of hardware and software systems that supports public key encryption and digital signatures, used to establish and manage trust relationships in UBDCN solutions.
