我的解释:

bitcny是由抵押三倍价值BTS(2倍自己出,1倍是卖空收入)卖空发行而来。这个抵押是实实在在的,卖空者在当时若去外盘市场上卖出BTS是可以拿到真金白银的。手持BitCNY的人不必担心,因为由止损止盈,爆仓,到期强制平仓等因素驱动,市场上必然会有回购Bitcny(以BTS计价)的挂单,从而保证了bitcny与bts的价值关联。这会达成一个市场平衡。

wall目前的功能是:大家发送给我信息,这些信息任何人都能看到,但无人可以更改。

其实技术上也完全可以实现:我(且只有我有权)发送信息到我的blogwall里面,任何人都可以浏览。
他们也可以在其下回复,这些回复也能被所有人看到。博主可以删除这些回复,等等。

然后别人可以选择关注我的ID,新的blog会自动列出等等。

不过这微博发出来要花钱,不过没人能删除,具体应用你懂的。。。

IIRC the proposed random number generation scheme had the problem that an individual delegate can decide to skip a block instead of producing a random number that would make him lose a game. (See https://bitsharestalk.org/index.php?topic=9489.msg139680#msg139680 ). Has that been addressed?

You can find infomation about this problem at
http://www.bitsuperlab.com/pdf/BitSharesPlayWhitePaper.pdf

Quote
The solution is as follows, the ticket result will be drawn by 2 delegates:
The first delegate's random number is only in charge of producing a number X between 1 and 3 that determines that the Xth block after him will draw the random number for the ticket. The 2th delegate could be the evil guy who is trying to attack, but he can not predict who will produce the right drawing block before 4 blocks, his attack cost is (3 * BLOCK_TICKET_SALE), but his expected return is still only 1 block_ticket_sale. The only thing game rule need is to set the draw interval 1 block before the first delegate.

目前还看不到PLAY的盈利模式,更看不到什么大的希望,加上进度慢且保密,不知道现在有多少人会积极的注册。
盈利模式简单的说就是PLS的使用,冻结和销毁。此外促进PLS价格上涨的重要因素就是用户规模效应,而这正是PLAY超越所有现有二代币的最大优势。

由于PLAY的用户群和BTS还是有比较大的差别的,所以是一个全新的社区。
欢迎对PLAY感兴趣的朋友加入社区讨论。

由于早期论坛用户大多由bitsharestalk.org迁移过来,为了使沟通不发生误会,我们希望保持ID身份的延续性。

如果你在bitsharestalk的常用ID在playtalk.org中被他人注册,请在本帖回复说明情况,我将以bitsharestalk的身份为准。

BitShares PLAY非技术白皮书

请访问 playtalk.org 获取更多信息

1.0介绍
BitShares PLAY(简称 PLAY) 运用区块链技术,试图建立一个去中心化的和自治的游戏平台。第三方可以基于此平台开发多种可证公平的游戏,包括一些从未有过的独特类型。这些游戏兼具娱乐性和公平性。同时PLAY的随机数生成器功能(技术实现详见附录)和自定义资产及交易功能可被第三方游戏开发商接入,为第三方游戏的公平性和资产发行及交易提供便利和技术保证。

2.0 PLAY 功能

2.1 PLAY平台支持的链上游戏类型
链上游戏是指游戏的全部逻辑都在区块链上定义并运行,不依赖于区块链之外的其他中心化机构(无外部的信任隐患)的游戏。

2.1.1基于概率的游戏
典型的如 Dice, Chance Coin类游戏。

2.1.2 趣味竞猜类游戏
关于某一件事未来是否会发生或如何发生的竞猜。例如,名人是否会在一个时间点之前结婚或离婚。外部事实发生后,信息需要输入区块链。在基于DPOS的BitShares PLAY中,可由受托人投票来完成这个任务。由于受托人是由PLAY持股者投票选出的,我们认为受托人投票的最终结果会是可信的(如果投票结果与事实不符,其后果由选举这些受托人的人,也就是全体PLAY持股者共同承担,在此意义上仍然是公平的)。

2.1.3投票驱动型的多人竞技类游戏
这是由ByteMaster提出的一种全新类型的互动游戏。举例来说,例如国际象棋。区别于传统的二人竞技模式,在PLAY上,用户分成两组。例如每个ID具有一个颜色字段,当前是黑组与白组用户竞技。轮到一方出招时,该组用户均有权按自己的想法出招,其权重等于该用户ID下的余额,最终这一方按照累计权重最高的着法执行,也即由该组用户投票决定。

这是一种前所未有的独特类型的游戏,即使在数字加密货币领域内也是首创。

2.1.4棋牌类游戏
该类游戏包括简单的棋类对弈游戏,也可能会探索一些桌游和扑克类游戏的可能性。

2.1.5概率与策略相结合的竞技类游戏
该类游戏是2.1.1类和2.1.4类游戏的综合体,具有运气成分同时也具有策略成分。类似的有Cannot Stop 和Bingo.   

2.2 去中心化的游戏资产定义和P2P交易市场
传统的游戏中一般都会有游戏币和游戏装备的概念。PLAY具备用户发行自定义资产的功能。这样游戏开发商可以在PLAY平台上发布自己的自定义资产(可以是游戏币,也可以是装备类物品),然后在自己的游戏内部支持这些资产的充值和提现, 或者直接读取blockchain上的资产账本以实现控制总量上限。同时PLAY提供这些资产的交易功能。玩家可以在PLAY的市场上自由买卖这些资产。通过这种方式,建立跨越不同伺服和游戏的p2p经济系统,取代传统游戏的自发行方式。

如果在2.1所述的链上游戏获得了极大的用户基数,可以预想游戏开发商会很想在PLAY平台上发行自己的资产来吸引用户的注意。届时可以引入发行自定义资产的资格竞拍等功能。当然这只是盈利模式之一,事实上当用户基数很大时,还可以有很多其他盈利模式。

PLAY鼓励将市场以内置的方式接入传统游戏之中,这样用户就无需要认识第三方平台,就可实现游戏资产的去中心化交易。

3.0 PLAY内置的随机数生成器算法简介
随机数有很多的应用场景,而随机数的生成是一个由来已久的问题。一个广泛的原则是:随机性的生成 最好不被任何个体所控制。因此譬如从比特币的未来某区块的数据来获取随机性的方式是不能使人信服 的,因为这些随机性最终实际上是由某个个体决定的,无法证明这个相关人没有作恶。

PLAY采用的是一种分布式的随机数生成算法,使用了DPOS结构中的受托人来提供随机性。受托人事先生 成私密的种子数据,然后生成区块时公布该种子数据的哈希值,在下一次生成区块时再公布该种子数据 。最终外部过程所使用的随机数由连续的多个(至少应大于等于101)种子数据来确定。这样只要有一位受托人是诚实的并将他们的信息保密,那么其他人就无法预测结果。那么我们可以很放心地假设 受托人中至少其中有一个是诚实的。这样产生的随机数可信程度是非常高的。

开发路线图
A基本的资产转账和ID功能, CP账户,内置兑换模型和交易模型
B 链上游戏平台支持(包括1-2个链上示例游戏), 自定义资产以及充值提取,读取API等功能

BitShares PLAY Non-technical Whitepaper

Please visit playtalk.org for more details

1.0 Introduction

Bitshares PLAY(PLAY in short)Leverages the block chain technology, attempts to establish a decentralized autonomous game platform. Any third party can develop various provably fair games, including types that are never seen before. These games feature entertainment and fairness at the same time. Meanwhile, PLAY embodies the function of random number generation (see appendix for technical details) and custom asset and exchange are accessible to third-party developers, providing fairness and asset issuing with convenience and technical support.

2.0 Functionality

2.1 Type of games supported by PLAY
On-chain games refer to games that run its entire logic on the block chain and that are independent from any external centralized institutions (no risk of trust)
 
2.1.1games on probability
Typically, Dice, Chance Coin and etc.

2.1.2 Quiz games
The guesswork of whether something will happen or how something will happen in the future.
For example, whether celebrities will get married or divorce in a specific amount of time
Data needs to be put into the blockchain after events happen off-line. On Bitshares Play, which leverages DPOS, the job can be done by delegates. Because delegates are elected by PLAYshares holders, we believe the results of vote are reliable. (If the result is obviously false according to facts, the consequence is shared by the PLAY shares holders who elected the delegates, which means it will fall on the whole community, in which sense, it is still fair.) 

2.1.3Multiple-person vote-based SPG
This is a brand new interactive multiple-unit game proposed by ByteMaster.
An example can best illustrate the mechanism. Chess would be different from its traditional form whereby only two people are involved, while on the PLAY platform there would be two groups of users. Every ID has its color field,making it a game between the black and the white game. How a round should be played will be determined by the group’s vote and the weight of each ID’s vote depending on the balance in the account of the ID.
This is an unprecedented type of game, even for the cryptocurrency field.

2.1.4 Chess Games
This type of game includes simple chess game and possibly board games and pokers.

2.1.5 Probability and Strategy Combined
This type is a combination of 2.1.1 and 2.1.4 which require both luck and planning, like Cannot Stop and Bingo.   

2.2 The definition of Decentralized Game Asset and P2P exchange

Traditional games have the concept of game assets and equipment. PLAY allows users to issue custom assets, which means game developers are allowed to issue their own customized assets (either game tokens or gear objects), and realize deposit and withdrawal inside the games or control the total amount of assets by reading the asset ledger on the blockchain. At the same time, the tokens and gear objects are exchangeable on the platform of PLAY. Players can freely purchase or sell these assets, through which, inter-server and inter-game p2p economic systems are established, replacing traditional asset issue models.。

If on-chain games as described in 2.1 gains enormous user base, PLAY is expected to welcome more game developers to issue their assets for users’ attention. By then, custom assets’ qualification bidding could also be introduced as one of the possible profit models when huge user base offers possibilities for many other revenue channels.

PLAY encourages exchange and market to be built in traditional games to realize decentralized game asset exchange without the necessary process to get familiar for the third-party platforms.


3.0 Introduction of PLAY’s built-in Random Number Generation (RNG)
Random numbers are used in many scenarios when their generations have been a problem for very long. A general principle is, the generation of random numbers is better to be done without any control of a particular individual. Therefore, to make a future block the source of random number is still unreliable, because the randomness is still in the end decided by a certain individual and it is impossible to prove whether the regarding individual is honest.
 
PLAY adopts a distributed algorithm for random number generation , leveraging delegates in the DPOS structure to provide the randomness. PLAY delegates generate private key data and publish the hash of the key data when a block is published.

In the end the random number employed is generated by a successive multiple (at least 101 or more) number of key data, so that as long as one delegate is honest and hasn’t leaked his data,。we can safely assume that no one could know the random number generated in the end, making the number fair and reliable.

Appendix:

Development Roadmap
A basic asset transaction, ID, CP accounts and built-in exchange and models of exchange and trading.
B on-chain game platform (including 1 or 2 on-chain game demonstration), custom assets issue, deposit and withdrawal, API reading
C light wallet
D Quiz game,, third-party game developer integration
