The xx network team has put together the xx coin game dapp as a fun way to test the xx network. The game is available for anyone to play, but only those who have already received xx coins (either through coin sales or as a node operator) are eligible to receive xx coins.
The game will be open from 1PM UTC to 3 PM UTC on April 6th, 2021 along with the Celebration Livestream, where David Chaum, the team, and some node operators will discuss the xx network, the xxDK and the xx messenger. The game will end after 500 plays.
To play, simply download the app, enter the Ethereum address (where you have already received xx coins) and a message.
Your message will travel privately over the xx network and the team on the live stream will read the message live (assuming it is not too raunchy and in a language we understand).
When playing the game, a cryptographic operation will use your message and a precommitted salt to randomly choose the number of xx coins you win!
Windows
- Extract the zip file.
- Click xx-coin-game.bat to run the game.
Linux
Linux64 (GUI required)
- Extract the zip file.
- From the command line, run ./xx-coin-game.sh.
Mac
- Extract the zip file.
- Open terminal, you can easily do this by pressing Command+Space and typing in Terminal, then pressing enter
- Type cd and space into the terminal, then drag the extracted folder on, and press enter
- Run xattr -rc xx-coin-game.sh as a command
- Run ./xx-coin-game.sh as a command
Playing the game
When you first open the app, it will need to connect and register with the network. This can take a few minutes. Once connected and registered, the screen will look like:
Then simply enter your Ethereum address and a message and click Send over xx.
The network is still a little buggy. If it doesn’t work, just try again. This test will give us the information we need to fix the last final issues.
If it doesn’t work perfectly the first time, please email the logs (assets/xx-coin-game.log) to [email protected] with a short description of what happened. This will help us get the network working perfectly!
