Recap | Use Cases on WenChang Chain, the Cosmos Tech-based OPB

On October 29, the Open-Permissioned Blockchain (OPB) Summit was held by Blockchain-based Service Network to discuss how global public chain partners can enter the Chinese market and comply with local regulations. Yifan He — RedDate Tech CEO, Jehan Chu — Founder of Kenetic, and Tim Bailey — Vice President of Global Sales at Red Date Technology, attended the summit and talked about outstanding features of Open Permissioned Blockchain (OPB) and its use cases.

Internet of Blockchains — the Future of Blockchain Industry

OPB like Wenchang Chain has inherited the best features from both the public chain and consortium chain, and leverages open consensus engine Tendermint with security, making it perhaps the best platform to build distributed business applications on.

OPB will take a considerable share of current more close formed consortium chains. And in her opinion, the future of blockchain is definitely the Internet of Blockchains composed mostly with public chains + OPBs.

Cosmos/IRISnet Tech-Based OPB — WenChang Chain

Launched on February 1st, 2021, WenChang Chain is the first batch of BSN Open Permissioned Blockchain. Cosmos has made major contributions to the blockchain industry, including innovative technologies like consensus engine Tendermint, the Interblockchain Communication (IBC) protocol, and the open-source blockchain development tool — Cosmos SDK. Cosmos supports very open interchain interoperability and the network layout is openly many hubs and many zones structure with each HUB and each zone are all sovereign chains. Today there are already public chain Hubs like cosmos HUB and IRISnet, and permissioned Hub for enterprises like IRITA HUB in the BSN environment.

Built with Cosmos SDK & IRISnet enterprise function modules, and combining open consensus engine Tendermint, WenChang Chain was made a competent tool in building distributed business applications as well as addressing complicated business needs. WenChang Chain refactored the advanced underlying technologies of public chains including Cosmos Hub and IRISnet to be compliant with enterprise standards.

WenChang Chain is also able to manage permission with Decentralized Identity (DID) and make permission control configurable on both validation level and account level. In addition, it adopts advanced big data & privacy-preserving technologies to implement the highest level of security for its users.

Use Cases on WenChang Chain

Since its launch in February, 2021, WenChang Chain has brought many business applications and use cases, including:

• Spider ID Trusted Identity Service provided by Nanjing One Identity Corp. that can be used in government service, e-commerce, and identity verification on the premise of protecting private data;
• MoKa (the permissioned version of Uptick App), a digital asset management app developed by the Uptick team & implemented on WenChang Chain that allows users to create, manage and cross-chain transfer NFTs;
• Electronic License and Certificate Issuing App that support Sichuan Dujiangyan Paperless Government Service. Based on the strong capacity of WenChang Chain in privacy-preserving and privacy computing, the Electronic License and Certificate Issuing App can support privacy-preserving data sharing, so as to reduce physical government office visits and turnaround time, improve process transparency and the quality of service to business and individuals.
• Supports Trustworthy Global Commerce of Chinese Traditional Artwork NFTs using the natively integrated NFT and iService technologies backed by Cosmos/IRISnet technology and powered by IRITA. With the developing interchain NFT technology that is compatible with mainstream NFT protocols and supports modeling and full life cycle management of complex data objects, WenChang Chain can help realize the trustworthy global circulation of Chinese traditional artwork NFTs.

In conclusion, OPB unleashes the potential of blockchain technologies and allows us to deal with more complicated business issues in an open system. It is foreseeable that in the near future, OPB like WenChang Chain could likely become the best choice for building distributed business applications and driving the blockchain industry towards broader adoption.
