How does it work?

This platform is partly running on a blockchain. Get to know how this technology works in the most playful manner. Just join a team and start playing.

Supported by a consensus algorithm, each team sets their stones in their quest for surrounding more territory than the opponent. Every player is rewarded with a PLAY token for their suggestion for the next move.

Collect one token for every move, every 20 seconds.
An Ethereum wallet is automatically created in the background when joining the game.
If you redeem tokens earned by playing, you will be asked for a password. The password protected wallet is then saved in your browser (local storage) for future Go sessions and can be saved for other usage.
The private key of your wallet never leaves your Computer.

Every move you propose is signed with the private key of your wallet. This signature is included in the game state which will be made available for every game played on this website.
A hash of the game state will be written to the blockchain (using this contract).
That way, despite the possibility to participate anonymously, progress of the games and the resulting token payouts can be made transparent and auditable.

For every token mined, a supplement token is generated and transferred into a pool (see contract).
That pool also accepts Ether donations before and after the gaming period.
At the end, collected Ether is donated to non-profit organisations fighting for privacy.
The collected PLAY tokens are transferred to the donators proportional to their contribution.

Can I also buy PLAY-tokens?

Yes. For every token mined, a supplement token is generated to sell. You can bid for these tokens. Secure a significant share of these tokens without investing time to play. The total of your investment will be donated to reputable non-profit organisations fighting for privacy.

Registration for the auction of PLAY tokens happens only from 25th and 26th of September and from October 29th to 31st 2017.

You can buy or sell tokens as soon as Play tokens are traded on Exchanges. Date is yet to be announced

more information

New to blockchain..? I am a newbie!

When playing this game, you will understand how the blockchain works and even get rewarded.

Understand the Blockchain!

Board games like Go show how decision-making works and convey the underlying principles of `consensus` and `finality` in complex networks. These paradigms are also used by the blockchain, the underlying technology of crypto-currencies like Bitcoin. The blockchain allows `transparent anonymity` that allows anybody to participate anonymously while displaying the results publicly.

Support Privacy!

By playing Go, the project Play4Privacy creates awareness for privacy in general and the blockchain in particular in the most playful and interesting manner possible. However, it is not required for the participants to understand the underlying technology to experience its value.

Get rewarded!

Nevertheless, you will get rewarded with a PLAY-token for your every move you join. Just join in and figure out the rules of the game and the blockchain. You do not need any prior knowledge. We will guide you through!
