Pollchain, which was launched in February 2021, is an SNS platform for knowledge sharing. Users can ask and answer various types of questions and concerns, ranging from daily life and relationships to social issues, business, and investment, using a method called "polling."

Pollchain has introduced a unique "protocol economic model" where users propose and participate in polls and share rewards. All users, including the Pollchain team, actively engage in creating and consuming content through polling. The economic value of the accumulated big data, user analysis index, and advertisement orders on Pollchain is collectively generated by the users, ensuring fair distribution of rewards.

The content on Pollchain combines polling and advertisement. Users consume advertisements while participating in polls and receive rewards in the form of POLL tokens. The use of blockchain technology ensures the credibility of polling data and user engagement, enhancing transparency in advertisement execution. As more users create and consume polling content, the exposure to advertisements increases, leading to the growth of Pollchain's value and the acquisition of more users in a virtuous cycle.

In May 2021, Pollchain announced the launch of the Greece stage. This stage aims to familiarize Pollchain users with the PollChain system through easy participation in voting content and proposals.
