NGK Global’s open source technology, opening a cross-chain ecosystem
According to the news, the emerging public chain project NGK Global has completed its own open source plan. Based on its innovative cross-chain communication and interaction scheme, the open source NGK Global will face the entire ecological node and provide an efficient, free, and borderless public chain ecology. system.
At present, everyone’s expectations for blockchain are focused on the emergence of a killer DApp. At the same time, as the foundation of multichain interconnection, structure and cross-chain technology have also become important representatives of “Blockchain 3.0”. NGK Global, as the bottom layer of the internet value, uses the blockchain as the carrier of the value interconnection of all things.
If the consensus mechanism is the soul core of the blockchain, then for the blockchain, especially the alliance chain and private chain, cross-chain technology is the key to achive the value network. It is the antidote to save the blockchain from a separate island and act as a bridge to expand and connect the blockchain.
1. The emerge of ross-chain is to solve the data island of blockchain
Under the current thinking trend of “each blockchain becomes an ecology by itself”, each chain has also become an information island with different technical architectures, disconnected from each other, and independent operation, which is very embarrassing for DApp developers.
The so-called cross-chain technology, as the name suggests, is to achieve asset circulation, information exchange, and application collaboration between different blockchains. It is similar to a bridge between different chains, achieving data transmission between different blockchain networks and greatly reducing transmission costs.
In today’s blockchain world, there is an urgent on the demand for cross-chain technology.
Cross-chain interaction can be divided into homogeneous chain cross-chain and heterogeneous chain cross-chain according to the different underlying technology platforms of the blockchain.
The security mechanism, consensus algorithm, network topology, and block generation verification logic among homogeneous chains are the same, and the cross-chain interaction between them is relatively simple. The cross-chain interaction of heterogeneous chains is relatively complicated, and the direct cross-chain interaction mechanism is not easy to design. Cross-chain interactions between heterogeneous chains generally require third-party auxiliary services to assist cross-chain interaction.
2. NGK Global deploys inter-chain communication, and upgrades technological innovation
NGK Global chose a homogeneous cross-chain and released space for cross-chain communication in the form of large block headers. Different from the difficulties and complexity of heterogeneous cross-chain, the inter-chain communication achived by NGK Global based on isomorphism has more landing value and possibility.
In addition, NGK Global’s cross-chain logic is “main chain + multiple side chains”, emphasizing “one chain, one scene”, that is, each side chain can be a scene, such as a DApp or a DeFi application. NGK Global’s cross-chain also has a central, which is the main chain.
In the cross-chain process, NGK Global uses a method called “index” to achive inter-chain communication. Index refers to the transmission of data from one chain to another. Therefore, NGK Global has formed such a cross-chain process:
The main chain first requests data from the side chain that needs to be indexed, and the side chain transmits data information to the main chain. This step is the main chain index side chain; then the main chain completes the information verification process, and the side chain requests data from the main chain, the main chain transmits data to the side chain. This step is the side chain indexing the main chain.
Cross-chain is achieve through two-step indexing. At the same time, it is not only the main chain and the side chain that index each other, there will be multi-level sub-chains below the side chain, which can also be indexed. From a more macro perspective, NGK Global’s cross-chain technology allows the parent and child chains to index each other to achieve cross-chain.
From this point of view, NGK Global does not need a central Hub or a relay chain, but a decentralized cross-chain model. Because not every inter-chain communication has to be allowed by the only main chain, the multi-level sub-chains under the side chain can also communicate with each other without passing through the main chain.
Under the premise of decentralization, NGK Global stipulates that only confirmed blocks can be indexed, because only data that is confirmed as irreversible can be trusted to ensure network security.
