Finally, we have deployed Open Emoji Battler on Shiden Network. To celebrate the launch, we have our first game event round with a 10,000 SDN prize pool. This post explains the event and how to participate.
Shiden Network is the only production blockchain with a Wasm smart-contract environment (pallet-contracts) in the Polkadot/Kusama ecosystem at this point. We have developed a fully on-chain game taking advantage of Wasm. Our advanced game mechanics couldnât be realized on EVM because of the computation complexity.
For those who are not familiar, Open Emoji Battler is a decentralized autonomous gaming project. The front end works on web browsers. Learn more in this article.
This event starts now and finishes at 2022-09-25 00:00 UTC.
Leaderboard
When players complete games, they get rating scores called EP. The leaderboard shows the top 100 players in the best EP. Players on the final leaderboard will get prizes based on their ranks.
The rewards are as follows:
- Top 100: SDN
- The 1st place reward is 600 SDN. The full reward table is here.
- Top 3: EMO NFT
- EMO:
- chain: Statemine
- EMO:
Weâll send these rewards after the event from our treasury.
When multiple players have the same EP, the player who scores the EP later places a higher rank.
If you want to show your name instead of your address on the leaderboard, you can set an identity on Kusama. The leaderboard shows the display name field. You need 0.034 KSM (lock and transaction fee) to set it. Judgment from registrars is not required.
Game
Anyone can participate in this event, but you need a small amount of SDN to cover transaction fees. 1 SDN (â 0.36 USD) is enough for dozens of games. You can also try the game without SND or a browser extension, but you wonât be eligible for the leaderboard.
Please refer to this guide to learn how to play, and access the game from our website.
For those who played this game before, here are the changes from our previous prototype version.
- Each playerâs EP newly starts from 300.
- Rivalâs initial healths change depending on the playerâs EP. While the playerâs EP is low, the rivalâs health is deducted.
- The higher playerâs EP, the smaller the EP increase.
- Some bug fixes.
- New EMOs:
| type | emoji | grade | attack/health | ability |

Notes
- The active contributor (@tash_2s) joins and plays this event as well. But, if they get leaderboard rewards, they will return them to the treasury.
- Because of the nature of the decentralized and permissionless world, using bots isnât prevented. However, itâs nearly impossible to develop bots stronger than humans within this event period, so thereâs no significant impact.
- Have fun! See you in the game.
