Answer

A blockchain bridge is a connector that connects two blockchains, which can be either isomorphic or heterogeneous, and allows data, value, assets, and operations to flow between them. Essentially, it acts as a bridge for different blockchains to communicate and interoperate.

A bridge link is a set of interconnected bridges that provide redundancy and decentralization for cross-chain operations between two blockchains. It ensures that even if one bridge fails, transactions can still be processed through other bridges, thus enhancing the reliability and resilience of the system.

The purpose of the Generic Transaction Payload (GTX) is to provide a standardized format for cross-chain transactions, which contains necessary information about the transaction, such as source blockchain ID, target blockchain ID, account address, fee, and transaction type.

A native transaction (NTX) refers to a transaction that occurs within a single blockchain, while a cross-chain transaction (CTX) involves the transfer of assets or data between different blockchains.

The API Gateway acts as a middleware between the client device and the rest of the cross-chain transaction system, it receives the GTX payload from the client, routes it to the appropriate blockchain (for NTX) or bridge link (for CTX).

The Bridge Link Registry stores important information about the bridge link, including the bridge ID, name, creation date, connected blockchain, transaction history, and lock status, which is essential for synchronization between all bridges and maintaining consensus on cross-chain transaction processing.

The validation process of a cross-chain transaction involves checking transaction parameters, such as blockchain ID, account, balance, and fee, and it also involves simulating the transaction to ensure that it is valid before it is considered valid and added to the Bridge Link Registry.

Cross-chain bridge proof of stake (CBPOS) is a consensus mechanism where the probability of a bridge being selected to process a transaction is proportional to its stake in the bridge fund.

Bridge funds are the collection of assets and values ​​deposited into all bridges in the bridge chain. Account owners contribute to bridge funds by locking their assets to specific bridges. Larger bridge funds mean greater trust and a higher probability of processing transactions.

Configuring a cross-chain bridge includes setting up bridge ports to connect to blockchains, establishing an interoperability consensus mechanism between bridges, configuring bridge IDs, and defining parameters such as transaction fee ratios and synchronization intervals.

Glossary
