Just thought of sharing a mining challenge that Blockstack & Daemon Technologies is organizing in view of their protocol going mainnet on 14th Jan'21.

Mining challenge: https://daemontechnologies.co/minestx-challenge

The first challenge will begin from 15th Dec'20 to 4th Jan'21 with up to 200,000STX token to be won(approx. USD55,000)

The basic requirement to be eligible for the prize would be to have your miner attempt to mine atleast 30% of all blocks during the period.

No major hardware requirements(I'm mining with a regular Windows laptop thats more than 4years old) and basic broadband internet connection will do.
