BOLT12 is the latest Lightning specification proposal that brings onion messaging, blinded paths, and payer proofs to Bitcoin's premier scaling solution. This black hat highlights the sleek BOLT12 design embroidered on the front of the cap. Looking closer, you will notice a small white Bitcoin ₿ within the "O" of BOLT, reminding us of where it all started.
The BOLT12 hat is in collaboration with Bitko.
