HashLeague is a leaderboard that ranks bitcoin communities on their hashrate. It's a game-ified way to encourage mining in your local community. In this workshop, we will show you how to setup your own instance of public-pool so that you can form a community mining pool, and offer project ideas if you would like to work on HashLeague during the hackathon.
UTC: June 14 7:00PM
Join us for a builder jam session. Here you can share what you are working on, ask for help, and socialize with other builders. In this session, we'll also be working with Bitmain S9 ASICs live at ATL BitLab. Anyone who shows up in real life who ha entered the hackathon is free to use an S9 as part of their project.

How innovative and impactful is your project idea? Does it solve a real problem in the bitcoin mining space? Could it contribute to miner decentralization?
How well was the project implemented? Is it technically sound and ready for real-world use?
Does your project make us see things differently? Did it make us say "wow"? Does it have an extra level of polish and zazz?
How well did you document and share your work? Did you engage with the community as you were building it?
