Couger's zkCREAM Selected for Development Grant by Ethereum Foundation

Couger Co., Ltd. (Headquarters: Shibuya-ku, Tokyo, CEO: Atsushi Ishii, hereinafter "Couger"), the developer of zkCREAM, a blockchain protocol that simultaneously ensures confidentiality and data reliability, has been selected by the Ethereum Foundation, the world's largest blockchain development community is pleased to announce that it has been selected for a development grant program by the Ethereum Foundation, the world's largest blockchain development community. We will proceed with the practical application of the open source project "zkCREAM" in the voting domain, which is already working with the Ethereum Core Team.

Importance of votes and tallies to ensure anonymity

There are many occasions, such as elections or surveys within an organization, where information must be tallied correctly while ensuring anonymity. zkCREAM anonymizes the votes, allowing each voter to be kept completely confidential. It also ensures transparency because it does not require a centralized third party and no one can tamper with the data.

So far, Couger has developed zkCREAM as open source, leveraging its experience in AI and blockchain development. Registered on Gitcoin, a platform that supports development by engineers, this project has raised over 1 million yen in support, mainly from overseas, and is now under development involving engineers from all over the world. In addition, we are working toward practical application, including technical discussions with the Ethereum Foundation's Zero Knowledge Team.
The company has been selected for the Ethereum Foundation's grant program because of these achievements and the promise of future expansion.

Expanding application areas through corporate collaboration

The digitalization of voting and participation in live events and shareholder meetings is accelerating, partly due to the impact of the new coronavirus infection. As a result, the importance of properly handling rights while protecting individual privacy digitally is growing. Against the backdrop of these growing needs, Couger will continue to expand its application areas through corporate collaborations.
