PSDC is an international blockchain-based project for the high-seas fishing industry, focused on traceability and business support. It is built on Ripple’s RTXP protocol as a decentralized, borderless public blockchain for the high-seas fishing sector. Initiated by Poseidon (PSDC) Lab and Russias Dalry East Company, PSDCs core functions are product information chaining and transaction accounting. It features unique smart contracts, cloud nodes, distributed trading, and new token circulation, forming a robust initial infrastructure. PSDC will become a new, decentralized commercial free cloud node available worldwide.
