Cross-chain, another trump card of PlugChain!

Preface: In the previous article, we focused on the field of PlugChain oracles. In fact, PlugChain also has advantages in the cross-chain function. How to open up the value bridge between Web2.0 and Web3.0, PlugChain’s DON provides a perfect solution. But how to get through the “information” and “value” transfer between independent blockchains, such as Cosmos and Polkadot are good, and PlugChain also gives the answer by virtue of its high-security and high-performance cross-chain collaboration capabilities. And this trump card lies in PlugChain’s flexible use of core technology.

1. Zero-knowledge Proof, safe consensus

With the vigorous development of the multi-chain ecology, the cross-chain protocol has become indispensable. However, because it carries a large amount of funds and has high technical and security difficulties, the cross-chain bridge has become the first choice for hackers. Looking back on 2022, cross-chain bridge asset theft incidents emerged one after another. Wormhole, Ronin Network, BNB Chain, Horizon, and Nomad lost hundreds of millions of dollars in funds due to hacker attacks.

Obviously, security is the most important issue for cross-chain protocols. Therefore, the Zero-Knowledge Proof technology solution using Trustless has become an essential choice for many cross-chain bridge solutions.

Zero Knowledge Proof, ZKP, as a trustless and decentralized solution to expand Ethereum, has been widely recognized by the blockchain industry. In the cross-chain industry, it also shows advantages such as trustless facility dependence, light computing on the chain, general purpose, and low latency. In particular, ZKP shows obvious advantages in solving current security at the trust level.

Essentially, Zero-Knowledge Proof is a cryptographic technique in which the prover can convince the verifier that the result is correct without providing any useful information to the verifier.

PlugChain securely and efficiently connects multiple blockchain networks and achieves seamless interoperability through ZKP technology. This innovation is very practical for cross-chain operations, allowing assets and information to be transferred between different blockchains in a trustless, secure and privacy-friendly manner without revealing sensitive information. At present, most cross-chain bridges still rely on centralized mechanisms to transmit cross-chain information, but ZKP can be used to eliminate this need for trust, which is the main reason why PlugChain uses this mechanism to build a new generation of cross-chain interoperability protocols.

In addition to technically solving trust issues, the cross-chain interoperability protocol built by PlugChain based on ZKP technology is applicable to many application scenarios. Therefore, developers can use PlugChain, a trustless and universal cross-chain infrastructure, to empower and expand application functions, and at the same time increase the imagination of blockchain ecological innovation, thereby bringing new application scenarios.

01. Asset cross-chain

Asset cross-chain bridge, the scene with the most cross-chain demand at present. PlugChain-based cross-chain asset trustless facility dependence greatly reduces the possibility of cross-chain bridge security incidents and eliminates users’ doubts about centralized bridges. At the same time, PlugChain has a high degree of versatility, is friendly to running or start-up cross-chain bridge projects, and supports a variety of cross-chain bridge models.

02. Multi-chain contract interoperability

PlugChain will provide the technical basis for multi-chain operations for the development of smart contracts, and apply efficient and safe multi-chain calls. Developers are not limited to the solid thinking of single-chain development, nor do they need to make trade-offs between the advantages and disadvantages of multiple chains. Just like developing the same-chain contract, it is easy to complete the interoperability call of the cross-chain contract. It enables the original applications to further enjoy the expansion of multi-chain interoperability, such as: multi-chain distribution of blockchain games, multi-chain lending in the DeFi field, etc.

03. Cross-chain Swap

Currently, the Swap application on the chain is limited to a single-chain ecosystem. Although it can be deployed on multiple chains, the assets between different public chains are severely fragmented, which limits the upper limit of Swap’s development. PlugChain can use ZKP technology to effectively solve existing problems and empower the official cross-chain Swap — GxSwap.

04. Trusted oracle on the chain

PlugChain can credibly transfer and store data sources to the target chain, and the information through PlugChain can be used by other DApps. This interaction allows other applications to determine whether a transaction (for example) occurred on the source chain. Different from other off-chain information collection oracles, the decentralized oracle based on PlugChain will be more credible due to the characteristics of zero-knowledge proof results.

2. Bridge all things, all-encompassing

Like bridges in the real world, the emergence of cross-chain bridges is to provide the same value for “interoperability protocols” and “common message layers”. Connect different public chains together. Without a bridge, moving from one chain to another is a very painful experience. But cryptographic bridges are more than connections, they allow translation of languages and rules between blockchains.

Bridges thus enable data to be transferred and interpreted between different environments, allowing interoperability between chains. It means that multi-chain will be the general trend in the future. The existence of cross-chain has resolutely become an indispensable part of the encryption infrastructure.

For cross-chain design, in addition to ZKP technology, what other advantageous technologies does PlugChain have?

First of all, PlugChain opens up a new way for cross-chain interaction between executions, and realizes the scalability of the public chain by virtue of the high-efficiency and independent data interaction of Cosmos and the underlying functional components of Polkadot. On the one hand, PlugChain relies on the oracle network to realize data interaction with each independent blockchain network. On the other hand, by using PlugChain Hub settings, it connects technical resources, business needs, existing blockchain functional components, and practical business chains. In order to meet different business needs while achieving scalability.

In the PlugChain ecology, PlugChain Hub is equivalent to a trading port extending in all directions. It not only has complete infrastructure, strong technical resources, and efficient circulation and interaction capabilities, but also can meet the needs of different blockchain cities and has strong scalability. In addition, PlugChain Hub features a wide range of cross-chain service application scenarios, including chain register, automatic market value management, Ethereum bridging, Bitcoin bridging, and the establishment of close connections with the wider digital economy, which is very rich! This is due to the advantages of PlugChain’s high scalability and high performance.

Secondly, PlugChain has innovated heterogeneous sharding technology in order to achieve data information exchange between different chains on the basis of ensuring scalability and efficient transactions. Because the block structure and consensus protocol between all shards are the same, PlugChain can efficiently realize the interoperability between independent blockchains in the sharded blockchain. In addition, PlugChain also integrates Ripple’s InterLedger protocol and Polkadot’s relay chain/side chain concept, innovating cross-chain intercommunication under state and asset sharding.

In addition, when only cross-chain asset transactions are required, the shard nodes of PlugChain that undertake this function can independently enable the lnterledger protocol (this protocol uses cryptographic algorithms to create fund custody for these two bookkeeping systems and connectors), when participating Parties can reach a consensus and can trade with each other, and only the system modules participating in the transaction can track the transaction, privacy is guaranteed, and the security of cross-chain asset transfer is improved.

To be honest, regardless of the highlight of the decentralized oracle, PlugChain is not inferior to the mainstream cross-chain bridge in terms of technical highlights on the cross-chain. Compared with cross-chain projects such as Cosmos and Polkadot, which have been in the ecological planning for a long time, the ecological scale has begun to take shape, and the ecological construction of PlugChain still needs to catch up.

Conclusion: The development of cross-chain protocols can be seen as a process of continuous decentralization and reduction of external conditional intervention. The cross-chain bridge built by PlugChain using core technologies such as zero-knowledge proof technology and heterogeneous sharding technology can truly realize the trustless assumption. After deployment, it only relies on mathematical and cryptographic algorithms to ensure cross-chain security. The dark horse of the field. In addition, on the basis of cross-chain assets, PlugChain will also realize the application of cross-chain bridges in DeFi, social, NFT markets and games. However, it is worth looking forward to whether PlugChain’s outlook on “DON” + “cross-chain” can produce the effect of “1+1>2”.
