The BSK project aims to apply blockchain technology to real life, providing users with a transparent and fair P2P reward structure. This project inherits the decentralized spirit of Bitcoin and is designed so that users can easily participate in the network and receive rewards through the Proof of Airdrop system without the complex mining process. Additionally, BSK offers various blockchain-based services such as GPS-based local advertising payment systems, NFT marketplaces, De-Fi financial models, and Move-to-Earn (M2E) services. Through these services, users can earn rewards through everyday activities and participate in local advertising or NFT transactions. Based on these services, the BSK ecosystem allows users to directly contribute to its growth and aims to improve the quality of human life through blockchain technology in the long term.
