$ZKJ ZKJ (Polyhedra Network) is one of the hottest tokens today, surging over 200–270% in the last 24 hours with trading volume exceeding $78–100 million far above its market cap. Polyhedra Network is a zero-knowledge proof (ZKP) infrastructure project focused on secure cross-chain interoperability and verifiable AI computations. It builds zkBridges and tools that allow trustless messaging and data verification across blockchains, while expanding into zkML (zero-knowledge machine learning). The token ZKJ is used for gas fees, staking, governance, and liquidity. The explosive move today has pushed its market cap to around $20–22 million, though it remains highly volatile with extreme price swings. This pump comes amid renewed interest in zero-knowledge technology and AI-related crypto narratives. However, with such massive short-term gains, caution is warranted as pullbacks are common in these high-beta tokens.
