SERO Blockchain 1st Global DApp Developer Competition

8 min readApr 19, 2020

Competition Introduction

SERO is a new generation privacy public chain. The core value is that SERO allows issuance of privacy-protected assets and supports rich asset data expression forms. These characteristics give SERO a unique advantage as compared to other platforms. SERO public chain is a well-known public chain project in China, has a strong technical team and a large community. In this context, led by the SERO Foundation, the “SERO Blockchain 1st Global DApp Developer Competition” will be held. We hope that through this competition, more excellent applications will be spawned to form a powerful blockchain developer application ecology. At the same time, it also shows the underlying technology of SERO public chain to global blockchain practitioners, which can make more people pay attention to China’s blockchain technology. In order to better incentivize technology developers to join this technology feast, the SERO Foundation has prepared a generous SERO token bonus with community donations to encourage outstanding technology developers to stand out in the competition.
