OxD9B4BEF9 University - Institute of Consensus T-Shirt

I love taking super technical Bitcoin details and giving them a classic, familiar feel. That was the whole idea behind my "0xD9B4BEF9 University - Institute of Consensus" T-Shirt. I designed the original graphic to look exactly like a vintage university tee. The number 0xD9B4BEF9 isn't random; it's the specific network identifier prefix found at the beginning of every Bitcoin mainnet block. I paired it with the 'Institute of Consensus' to complete the high-signal OPSEC design. It’s printed on a premium, comfortable t-shirt. Represent the institute.
