Cross-Chain Contract Protocol

The cross-chain protocol aims to solve functional issues pertinent to the transfer and exchange of assets on two or more differential chains. This protocol allows for assets to be transferred from a main chain to other subsidiary blockchains, and vice versa.

In blockchain, there are numerous main chains such as the Bitcoin chain, the Ethereum chain, the Tron chain, the Binance Smart Chain, etc., and each main chain possesses its own comprehensive ecologies. Before the emergence of cross-chain technologies, main chains were unable to communicate directly between one another. For example, a Bitcoin holder may not participate in Ethereum’s ecology because the two main chains are fundamentally different and are unable to communicate directly with one another. Given the rapid development of the cryptocurrency industry in recent years, this limitation would undoubtedly create technical transfer issues, thus cementing the need for cross-chain technology in blockchain.

Optimization is essential for cross-chain transactions to match the speed of blockchain generation between differential main chains. As such, the QBRIDGE smart contract was designed to meet such cross-chain demands. Firstly, the bridge connection smart contract protocol allows for the main chain to be divided into different stratums in accordance to the chain’s block generation speed. Thereafter, a proprietary adaptation chain or adaptation module for each layer is deployed to drive cross-chain transactions within the same layers. Subsequently, cross-chain guarantee mechanisms would facilitate cross-chain transactions at differential layers, whereby a slower main chain would serve as an effective solution to enhance the speed of cross-chain transactions. For QUATRO, this interactive exchange feature within its ecosystem is connected through the four major TUBE protocols.

The QBRIDGE protocol is a fragmented blockchain which connects multiple chains within a network, thus allowing differential chains to process transactions in parallel, exchange data, and provide enhanced security. By bridging multiple dedicated chains to a fragmented network, multiple transactions may be processed at the same time as the system is designed to eliminate data bottlenecks of previous networks where transactions are processed one by one.

The QBRIDGE protocol will be further expanded in the future through nested relay chains, which will increase the number of fragments that can be added to the network.

Through cross-chain composability and transferability, fragments are allowed to communicate, exchange values and share functions, thus opening doors to a new era of financial innovation so as to truly implement the concept of blockchain to empower real economies and establish the platform as a cornerstone of the digital economy.
