AI artwork of a hydro-cooled Bitcoin miner: glowing power cables feed energy into the machine, transactions stream into a block above it, and a bitcoin rises from the block — Interactive 3D visualization of an Antminer S21j XP Hydro-style machine turning electricity into proof of work. Live projected-block transaction counts come from the Bitcoin mempool; the animation is time-compressed.
