We Open Source and We Got Hacked

Dear players and developers,

We are glad to announce EOS.Win open-source on Nov. 11th. All smart contract code is open-source now, including Dice, Lottery, Blackjack, Jackpot, Dividend Distribution, and Lucky Draw. The code address is :

https://github.com/eoswindev/contract

Unfortunately, we are hacked on the first day we open-source. The attack is smart and tricky. We are now discussing with two blockchain safety teams, Slow Mist and Safe Comet.

EOS.Win is not like most of other EOS gaming platforms. We have no server side program. All game logic is running on blockchain. We believe that EOS can do this pure blockchain game based on smart contract, which is transparency and fair enough. But we were hacked again and again. Three times, lost almost 20,000 EOS.

But we believe in EOS. We believe that EOS can give us opportunity to have this blockchain games happen. We hope that all EOS developers, who is interested in helping developing more solid smart contracts, can join our discussion and together make EOS a better world for blockchain developers.

We will move on!

我们很高兴的宣布在11月11日这个程序员的日子开源，开源的代码包括EOS.Win平台上所有的游戏，猜数字、21点、大乐透、Jackpot玩法、分红池机制、幸运抽奖等等，开源的地址在这里：

但是不幸的是，我们开源的第一天，就遭受了随机数攻击。目前查明，攻击的手法很高超。我们目前正在和慢雾科技、数字彗星两个安全团队进行沟通，复盘整个攻击过程，以便修复漏洞。

EOS.Win和其他大部分游戏平台不一样，采用了“无服务端程序”的形式，是一种纯粹的EOS链上游戏。但是，我们被黑客攻击了三次，总计损失达20,000 EOS。但是，我们都是EOS的支持者，我们深信，EOS是可以实现这种无服务端的真正的去中心化应用的。因为只有保证用户直接和区块链交互，才能保证游戏的透明和公正。

我们希望全世界的EOS技术爱好者能和我们一起分析智能合约代码，一起来修复漏洞。我们没有悬赏（我们已经输光了所有EOS.Win平台赢来的钱），但是大家能够一起把EOS智能合约完善的更牢固，为未来的合约开发者提供经验和帮助。希望技术爱好者加入这个电报群，一起讨论EOS合约可能遭受的攻击：
