An article to understand the alliance chain cross-chain solution Poly Enterprise

When the alliance chain begins to be established on a large scale, like the Internet, it will also face the problem of new data islands, and the cross-chain between the alliance chains will become a rigid demand.

In this article, we will sort out the information of the alliance chain cross-chain solution Poly Enterprise to illustrate an alliance chain cross-chain solution.

On October 31, 2020, Onchain and the blockchain service network BSN reached a strategic cooperation and completed the Poly Enterprise cross-chain service in the BSN Interchain Communications Hub (Interchain Communications Hub).

BSN was jointly initiated by the National Information Center, China Mobile, China UnionPay, and Beijing Jujube Technology. It is a global blockchain infrastructure interconnection network that crosses cloud services, crosses portals, and crosses underlying frameworks. The integrated cross-chain service provided by the BSN cross-chain communication hub is a core component of the BSN technical system. The goal is to enable data between various types of blockchain heterogeneous underlying frameworks to be interoperable with low cost, convenience, and reliability.

Poly Enterprise joins BSN’s Inter-Chain Communication Center (ICH), which will provide developers with better services by reducing the cost of Dapp development, deployment, operation, maintenance, connection and supervision.

Poly Enterprise can use BSN’s ICH to enable all Dapps to make smart contract calls between blockchains, resulting in a more flexible and broader technical architecture and business logic. BSN is also expected to reduce the economic and technical barriers for developers to implement and apply blockchain technology through Poly Enterprise.

For example, Poly Enterprise has achieved interoperability between Hyperledger Fabric and the FISCO BCOS protocol, and plans to implement it between more chains to build the next-generation Internet infrastructure.

Poly Enterprise originated from the cross-chain interoperability protocol of the distributed technology Onchain, which can realize the cross-chain intercommunication of any information between heterogeneous chains, allowing seamless collaboration between heterogeneous alliance chains, and finally achieving consistent cross-chain information transactions sex.

After launching, Poly Enterprise’s cross-chain service has integrated the four blockchain frameworks of Fabric, FISCO BCOS, Ethereum and Neo, and also supports the Fabric application chain, FISCO BCOS application chain, Ethereum Ropsten, Neo Testnet in BSN. Cross-chain calls between application smart contracts.

Prior to this, the author learned about the idea of ​​distributed technology in cross-chain design from Da Hongfei, the founder of Distribution Technology.

Da Hongfei said that cross-chain is an important technical module under the grand design goal of pursuing interoperability. Interoperability will include interface standards, data format definitions, atomicity of operations, and licensing during operations.

According to the core logic of the blockchain: the use of cryptography to achieve operational validity, or legality (not legal legality) verification. Most of the permissions need to be released, that is, when interacting with an asset or an operation, there is no need for a centralized organization to license.

Therefore, there is no need for a separate license when interacting with smart contracts and applications in the interoperability chain or on the chain.

Designed from this idea, distributed technology chooses to build a chain, by synchronizing the block headers of each chain, and then verifying the block headers by the verifier of the Poly chain, realizing the asset transfer between cross-chains and the transactions between cross-chains Consistent operation.

Therefore, Poly has extended two versions, one is called Poly Network and the other is called Poly Enterprise. Poly Enterprise is the business-oriented version of Poly Network.

Poly Enterprise is mainly thinking about how to integrate with more private chains and alliance chains to manage permissions and meet the requirements of supervision or business users for licensing.

Poly Enterprise comes from the technical ideas of Distributed Technology. On August 3, 2020, IEEE C/BDL held a P3200s standard review and kick-off meeting in Hangzhou. The working group led by Distributed Technology Onchain, Ant Group Antchain, and Baidu Superchain led the formulation The P3204, P3205, and P3203 “cross-chain interoperability” series of standard project proposals have been approved, with the goal of achieving the following three major innovations in the cross-chain field:

1. Solve technical difficulties such as large differences in algorithms and underlying architectures between blockchains, insecure cross-chain information, and low execution speed of cross-chain transactions;

2. Help member chains access different underlying platforms quickly, conveniently and at low cost, and support application scenarios with transaction consistency requirements;

3. Unicom’s isolated blockchain ecological islands will build a next-generation Internet innovation model.

Among them, Distribution Technology proposed P3204 Standard for Blockchain Interoperability-Cross Chain Transaction Consistency (Cross Chain Interoperability Transaction Consistency Protocol)

The P3204 cross-chain interoperability transaction consistency protocol standard not only supports the cross-chain agreement between homogeneous chains, but also realizes the transactional consistency of arbitrary information between “heterogeneous chains” between cross-chain and cross-chain information, which makes up for the gap in the current market. .

The “Cross-chain Interoperability Transaction Consistency Protocol” adopts the logic of implementing SPV (Special Purpose Vehicle) at the bottom of the relay chain to transfer cross-chain transactions to the relay chain, and then the relay chain transfers the cross-chain Transactions are distributed to other chains for execution. Other chains will return the execution results to the relay chain after executing the cross-chain transaction. After receiving the execution result of the cross-chain transaction, the relay chain will distribute the execution result to other chains. A unified successful operation is performed on the chain, and the next transaction is operated on multiple chains to achieve simultaneous success or failure. In this way, the serial transaction becomes a parallel transaction, which can greatly improve the efficiency of cross-chain transactions.

At the launch meeting, AntChain proposed P3205 Standard for Blockchain Interoperability-Data Authentication and Communication Protocol (cross-chain data authentication and communication protocol)

The P3205 standard is a data authentication protocol and communication protocol oriented to homogeneous and heterogeneous cross-chains. It aims to solve the problem of data mutual recognition of the underlying foundation of heterogeneous cross-chains, and build inter-chain communication channels to allow blockchains Multi-mode cross-chain interoperability can be performed universally and flexibly at multiple application levels.

The P3205 standard can provide a unified data format for different types of blockchains, allowing blockchains that speak different “dialects” to use “standard Mandarin” for cross-chain interaction; in addition, a reliable and safe data transmission channel is established , Allowing businesses to exchange value flexibly in the value Internet composed of blockchains, and cross-chain full links are credible, traceable, safe and controllable.

Baidu Super Chain proposed P3203 Standard for Blockchain Interoperability-Naming Protocol (cross-chain interoperability naming protocol)

The P3203 cross-chain interoperability naming protocol standard, also known as the cross-chain addressing protocol standard, assigns an address to each resource on the blockchain network, so that any blockchain network can quickly locate the desired access across the chain through a standardized address A certain block chain of and get related resources.
