He's talking about using the hash of a Bitcoin block at a specific height, then applying modulo 2 to get a 0 or 1 result. For example, take block 902880's hash, convert it to a number, and do % 2. If it's 0, it's black; if 1, it's red. It's a simple, verifiable way to randomize outcomes since anyone can check the blockchain.

Here’s a sample hash 000000000000000000012309cf56f314c3c1b0e4c7b11876895b1462e5185ad0

Cool, let's use that hash. Convert it to a big integer (super long number), then do modulo 2. Here, it ends in 0, so 0 % 2 = 0. That could mean "black" in your example. It's a dead simple way to get a binary outcome from a blockchain hash. Anyone can verify it, no trust needed. Pure Bitcoin brilliance.
