16th Edition
Welcome to the 16th edition of the revamped PAI Newsletter! There is a lot going on this week, we hope you enjoy the updates & announcements. 
Announcements 
- PAI Coin is listed on two new exchanges: Livecoin and Alameda OTC
- PAI Coin Pool is launching Tiered Staking Rewards! This feature will increase the amount of staking rewards all users earn when the total amount of PAI Coin staked on PAI Coin Pool passes certain levels. See the schedule below for more information.
- PAI Coin Pool Gold is hosting a livestream event with leading NBA skills trainer, Rob Mac. Rob will talk about his experiences working with some of the best-known athletes in the NBA. All PAI community members are invited to join as a sneak peek into the type of engaging content that will be offered through PCP Gold.
- Calling all UI/UX designers! Project PAI is presenting a challenge for proposals on how to integrate Stake Vouchers for Hybrid Consensus into PAI Coin Pool. Good submissions will be rewarded in PAI. See below for more details.
For each increase of 25 million PAI Coin staked across all users, the staking block reward will increase by 25 PAI Coin. The full list of tiers is available here. The tier will be updated weekly on Mondays and announcements will be made when the tier is changed. Note that the tier can be downgraded at any time if a significant decrease in staking activity occurs, so it is in everyone’s best interest not to cancel stakes that are in progress.
On August 8, 9:00am Beijing Time (August 7, 6:00pm PDT), PAI core contributors will be hosting an AMA livestream about the NBA featuring basketball trainer Rob Mac. Rob is a world-class professional basketball trainer who creates personalized, intensive training programs for basketball players of all levels, from high school players to NBA All Stars. Rob trains some of the top players in the NBA, including MVPs Derrick Rose, Kevin Durant, Steph Curry and Russell Westbrook.

Calling all UI/UX designers
As mentioned in last week’s PAI Hybrid Consensus Live Stream session with Dr. Mark Harvilla, we are making a call for UI/UX design proposals for PAI Coin Pool. Once Hybrid Consensus is launched, we are exploring the possibility of enabling users to directly purchase individual Stake Vouchers through PAI Coin Pool. We ask any UI/UX designers to submit proposals and ideas on how best to seamlessly integrate this feature into PCP. We encourage you to submit UI mock-ups, user flow diagrams, and a description of the User Experience (UX) you recommend. Send submissions to challenge@projectpai.com before August 18, 2020. All high-quality submissions will be rewarded with PAI Coin. A special Grand Prize will be awarded to the best submission and announced in the PAI Newsletter. More details to follow.
