Project PAI 最新进度 (比特币减半特辑) -2020年5月12日

欢迎订阅 PAI新闻第六期,我们将回答一些有关PAI混合共识和有用工作量证明的问题和分享目前的技术更新,当然,还要庆祝著名的比特币减半。

重要公告

01

➔ Project PAI 技术路线全球AMA直播将在北京时间5月16日(星期六)上午10点开始。Project PAI 会在5月16日直播前在指定渠道发布 Zoom 会议链接。(详见Project PAI全球AMA直播最新安排

➔ PAI Coin Pool 促销推广正在进行中!将从5月15日星期五早上8点开始到5月22日星期五晚上11点结束,符合以下条件的用户都将获得 10PAI币奖励:

◆ 锁定权益至少1000 PAI币并时间超过三个月以上的,或者

◆ 开采40,000个幸运哈希

➔ 第一个启用PAI Pass SSO的产品正在 beta.paiforum.com 上发布。

比特币减半

02

就像四年举办一次的奥运会一样,比特币的区块奖励每四年将自动减少一半(PAI币也是如此!)。这次减半已于北京时间5月12日星期二凌晨3:23完成,区块奖励已经减少到了 6.25 BTC。

下面是一些有趣的事实:

➔这是比特币区块奖励的第三次减半。当比特币在2009年1月3日首次推出时,区块奖励为50 BTC。

➔自从最近一次的减半以来,比特币的价格已经上涨了1530%,从每个比特币约650美元涨至目前将近10,000美元。

➔与法定货币相反,按照协议规定,比特币的存在数量不能超过2100万个。当流通的比特币超过1800万时,则证明已经开采了近90%的比特币。除非基础协议发生任何更改(或哈希率发生剧烈变化),否则剩余10%的比特币将在未来40年中开采完毕。

这与PAI币有什么关系?

03

PAI币是基于比特币的代码分叉,因此许多比特币的属性(如区块奖励减半)也同样适用于PAI币。

➔与比特币不同的是,PAI币的初始块奖励是(现在依旧是)1,500 PAI币。PAI币的区块奖励的第一次减半将在2021年10月左右发生,那时区块奖励将减少到750 PAI币。

➔PAI币的创世区块于2018年2月23日被开采。截止到现在,已有134,885个区块被开采,自PAI币推出以来,平均开采区块时间约为8分36秒。

PAI 减半挑战

快来从PAI币的创始区块中找到隐藏消息。

第一个将正确答案发送到 challenge@projectpai.com 的人将赢得500 PAI币!

 

常见问题(持续更新)

04

PAI 混合共识:作为PAI币的所有者,我将如何受益于混合共识机制?

正如你所知,混合共识机制的目标是通过使其完全安全地删除区块链挖掘中的白名单,来实现PAI 币网络的去中心化。由于其固有的冗余性,去中心化网络不易遭受停机时间的影响,并降低了对恶意攻击的敏感性。因此,对于拥有、使用或依赖PAI币网络的任何人来说,这都是一个巨大的好处。

混合共识协议的设计增加了额外的安全性。在单纯的工作量证明(PoW)区块链上,累积大部分哈希率的网络参与者可以有效地控制(并恶意更改)交易。相似的,对于单纯的权益证明(PoS)区块链,持有多数股权资金的任何人都可以控制事物。通过将两种方法结合起来,可以大大降低对51%攻击的漏洞。

另外,在PAI Coin Pool 的推动下,通过将采矿和锁定权益活动纳入协议,混合共识可以使网络参与者有更多机会获得PAI币。

PAI Newsletter – May 12, 2020

In this sixth edition of PAI News, we’ll answer some additional questions about PAI Hybrid Consensus and Proof of Useful Work, share technical updates—and of course—celebrate the famed Bitcoin halvening.

Announcements

➔The Project PAI Tech Roadmap Livestream & AMA has been scheduled for Saturday, May 16 at 10 AM Beijing Time. A zoom link will be sent soon.

➔PAI Coin Pool is running a promo! Starting on Friday, May 15 at 8 AM through Friday, May 22 at 11 PM, anyone who:

◆Creates a stake of at least 1,000 PAI Coin for 3 months or longer, OR

◆Mines 40,000 Lucky Hashes

will receive a bonus of 10 PAI Coin!

➔The first PAI Pass SSO-enabled product is live at beta.paiforum.com.

The Bitcoin Halvening

Like the Olympics when there’s NOT a pandemic , every four years Bitcoin’s block reward is automatically cut in half (this happens to PAI Coin, too!). This time —at 3:23 AM Beijing Time on Tuesday, May 12—the block reward was reduced to 6.25 BTC.

Here are some interesting facts:

➔ This is the third halving of Bitcoin’s block reward. When Bitcoin was launched on January 3, 2009, the block reward was 50 BTC.

➔ In the time since the most recent halving, 4 years ago, Bitcoin’s price has increased by over 1,530%, from around $650 per BTC to nearly $10,000 per BTC as of this writing.

➔ In contrast to fiat currency, no more than 21 million Bitcoins can ever exist, by design. With over 18 million Bitcoins in circulation, nearly 90% of all Bitcoins have already been mined. Barring any changes to the underlying protocol (or frenetic changes in hash rate), the remaining 10% of Bitcoins will be mined over the next 40 years.

What’s PAI Coin got to do with it?

PAI Coin is based on a code fork of Bitcoin, so many of its same properties—like the block reward halving—apply to PAI Coin, as well.

➔ Unlike Bitcoin, PAI Coin’s initial block reward was (and still is) 1,500 PAI Coin. The first halving of PAI Coin’s block reward will occur around October 2021, when the block reward will be reduced to 750 PAI Coin.

➔ PAI Coin’s genesis block was mined on February 23, 2018. Since then, 134,885 blocks have been mined (as of this writing), which gives an average block time of around 8 minutes and 36 seconds since PAI Coin’s launch.

The Halvening Challenge

Find the hidden message in PAI Coin’s genesis block.

(Hint: It’s in the “Coinbase” transaction.)

The first person to send the correct message to challenge@projectpai.com will win 500 PAI Coin!

Frequently Asked Questions

PAI Hybrid Consensus: As an owner of PAI Coin, how will Hybrid Consensus benefit me?

As you probably know, the goal of the Hybrid Consensus mechanism is to fully decentralize the PAI Coin network by making it completely safe to remove the whitelist on blockchain mining. Because of its inherent redundancy, a decentralized network is less vulnerable to downtime and has reduced susceptibility to malicious attacks. So, that’s one huge benefit for anyone that owns, uses, or relies on the PAI Coin network.

This additional security is compounded by the design of the Hybrid Consensus protocol. On a pure Proof-of-Work (PoW) blockchain, a network participant who accumulates a majority of hash rate can effectively control (and maliciously change) transactions. Similarly, for a pure Proof-of-Stake (PoS) blockchain, anyone holding a majority of staked funds can control things. By combining both approaches, vulnerability to so-called 51% attacks is greatly reduced.

Furthermore, facilitated by PAI Coin Pool, Hybrid Consensus gives network participants more opportunities to earn PAI Coin by incorporating both mining and staking activities into the protocol.

PAI Weekly Updates

PAI Forum and PAI Pass

Last week, a beta version of the new Discourse forum was made available to staff and community leaders. This beta is for testing and latency optimization purposes. It includes a fully-functional PAIPass SSO signup and signin integration.

This week, work is being done to improve the UX of the PAIPass SSO integration. Automated testing and deployment optimizations continue to be implemented on an ongoing basis. The technical staff are taking feedback and input from community leaders to ensure that the new Paiforum is fast and easy to use.

PAI Coin Pool

Last week, the PCP Referral and Sign-Up Bonus System was finalized, extensively tested, and launched! This week, as noted in the Announcements, we’ll be running a promotion and all users will have a chance to earn extra PAI!

Some other new features in the works include:

●Making it easier for you to see the details of pending withdrawal requests and modify or cancel them, if necessary

●Making it easier for you to share your referral code or link on your favorite social network

●Sending you an email summary of your recent activity on PAI Coin Pool

●Showing you more details about your Referral Rewards earnings
