Architect
From Block 115,000 to 209,999, an Architect named Veridian emerged from the GPU era’s nascent hum, a tireless tinkerer who pushed Bitcoin beyond hobbyist CPUs, meticulously crafting and experimenting with the very first dedicated mining rigs. His ingenious designs, born of relentless early scaling experiments, transformed scavenged components into powerful engines, heralding an era of industrial-scale mining previously unimaginable. Veridian's blueprints, etched in the silicon of those pioneering machines, forever laid the foundational architecture for all future miners and builders of the digital frontier.
