How does UBCDN handle changes in the underlying network configuration of a blockchain instance?

How do relays use UBCDN in a unified blockchain network?

One of the advantages of UBCDN is that it is user-friendly. Explain how this is achieved.

Answer

UBCDN acts as a unique identifier for each blockchain instance in a unified blockchain network. It simplifies addressing and accessing blockchain instances across different blockchain platforms.

Similar to how domain names identify resources (such as websites) in IP networks, blockchain domain names are also used to identify specific blockchain instances. Both provide a user-friendly way to replace complex numeric addresses.

Blockchain domain names facilitate cross-chain interactions by acting as globally identifiable addresses. Any blockchain instance can use UBCDN to locate and interact with other blockchain instances without knowing their underlying technical details.

UBCDNs typically consist of a human-readable label (the blockchain domain name) and a chain identifier that corresponds to it.

The chain identifier provides technical information about the underlying network configuration of a blockchain instance, such as the genesis block hash or network ID. It allows nodes to establish a connection to a blockchain instance.

The CA establishes trust by issuing a digital certificate to the UBCDN owner. This certificate proves that the CA has verified the owner's authority over the blockchain domain name, thereby increasing trust in the UBCDN.

Verifying a UBCDN typically involves checking the validity of the domain certificate, verifying the signature of the certificate authority, and verifying the signature on the UBCDN using the public key of the UBCDN owner.

UBCDNs allow blockchain instances to retain their domain names when network configurations change. UBCDN owners can reflect changes by updating the chain identifier without changing the blockchain domain name itself.

Relays use UBCDNs to resolve the chain identifier of a requested blockchain instance. Relays can then use this identifier to establish connections and facilitate cross-chain interactions between different blockchain instances.

UBCDN achieves user-friendliness by using human-readable labels (blockchain domain names). These labels are easier to remember and identify than complex numeric addresses, providing a more convenient experience for users.

Glossary

Term Definitions Blockchain A distributed ledger technology used to record transactions and maintain data integrity. Blockchain Instance A blockchain network deployed on a specific blockchain platform (e.g., Ethereum, Bitcoin). Cross-chain Interaction The process of communicating and transacting between different blockchain instances. Unified Blockchain Domain Name (UBCDN) A unique identifier for a blockchain instance in a unified blockchain network, similar to a domain name in an IP network. The human-readable portion of a blockchain domain name in a UBCDN, such as "example.chain". Chain Identifier A technical part in UBCDN that contains information about the network configuration of a blockchain instance, such as the genesis block hash or the network ID. Certificate Authority (CA) A trusted entity that issues digital certificates to verify identity and establish trust. A domain certificate is issued by a CA to a UBCDN owner, proving its authority over a blockchain domain name. Relay A node or network that facilitates cross-chain communication between different blockchain instances. Genesis Block The first block in a blockchain that contains basic information about the blockchain network configuration. The network ID distinguishes the parameters of different blockchain networks, even if they use the same underlying technology.
