BGN/CORE: Convert Bulgarian Lev (BGN) to Core (CORE)

TON (The Open Network) is pushing the potential of blockchain technology to new heights. Originally developed by the Telegram Messenger development team and later taken over by the community, TON aims to build a fast, secure, and scalable blockchain network. As a cutting-edge blockchain project, TON has attracted numerous developers and users with its high performance and flexibility, particularly with its potential to reach millions of TPS. With the continuous growth of its ecosystem and ongoing technological iterations, TON is poised to become a significant player in crypto space, promoting the adoption and development of decentralized applications in the future. It is worth noting that on September 6, 2024, OKX Web3 officially launched its new App Connect protocol, with current support for the TON ecosystem and upcoming expansion to popular networks such as EVM and Solana. This upgrade enables developers to seamlessly access the OKX App wallet directly via the Telegram Mini App for signing transactions and other DApp interactions. By integrating with App Connect, developers can efficiently build their own DApps on TON and Telegram, streamlining the development process and laying the groundwork for a more robust Web3 ecosystem. This issue is the second in the "Developer Stories" series, providing insights into the TON world from the perspectives of TON core developers and the OKX Web3 technical team. The topics covered in this issue include TON's technological advancements, developer support, community governance, ecosystem security, and more, aiming to understand the insights and plans of TON core developers from a deep level.
