The article began: Maya’s pulse quickened. The page was filled with a schematic—an intricate diagram of a server rack, a series of arrows connecting nodes labeled “A‑1,” “B‑3,” and “C‑7.” Beneath it, a paragraph in plain text read: The prototype, codenamed “Echo,” is a decentralized ledger that not only records transactions but also predicts their outcomes by cross‑referencing publicly available datasets. By integrating weather patterns, social media sentiment, and supply‑chain metrics, Echo can forecast market shifts with an accuracy previously thought impossible. Maya frowned. Echo? That sounded eerily similar to the early research papers on predictive blockchains she’d read during her graduate studies. But Subrang had never mentioned anything like that publicly. She turned the page.
