Greetings from the ICON Team,

The ICON Team is launching the ‘ICON TX (Transaction) Challenge’, a large blockchain development contest with a total prize pool of 1 million ICX (ICON’s cryptocurrency), starting on June 3rd.
>> Pre-registration & Request Test ICX

In order to support developers around the world with the goal of developing the blockchain ecosystem, the ‘ICON TX Challenge’ takes the form of a competition in which participants produce their own DApps(Decentralized Applications) or websites. Future blockchain experts including developers, university students, and anyone who has ideas to implement the blockchain technology in building services or wants to experience new technologies can participate in this contest.

The ICON Team plans to provide operating costs and technical support to participants during the contest, which runs for approximately two months starting from June 3rd to July 31st. Where existing development efforts have been slowed down by factors such as transaction (TX) costs, server hosting costs, and technical barriers, the ‘ICON TX Challenge’ will allow participants to access new technology and quickly validate their ideas.

In order to participate in the contest, smart contracts that can generate transactions should be completed in advance. After completing the production and verification of ‘SCORE (Smart Contract On Reliable Environment, ICON’s own smart contract development environment)’ using the ICON protocol, one can apply for participation by developing DApps or websites utilizing the SCORE. Teams who are confirmed to take part after the application process will be given 200 ICX each as a participating prize and a separate reward of 0.01 ICX per 1 TX for transactions occurring through the SCORE during the contest will be given out.

In addition, a total of 6 teams will be selected according to the evaluation standards including the completeness, business value, technicality, blockchain utility, etc. of DApps or websites. These teams will be awarded the final prize of 50,000 ICX per team. The evaluation of DApps and websites will be based on the state of the DApp/website on the ending date of the contest. ICON is also considering additional benefits such as helping attract investment to the participating teams, providing extra points for recruitment of the ICON office in Korea or internship opportunities.

As the ‘ICON TX Challenge’ is also an open demonstration of the stability and transaction processing performance of the ICON Mainnet, we expect many future blockchain experts to participate. Join the ‘ICON TX Challenge’ to win massive rewards and experience ICON’s DApp development environment!
