上海数通链谷竞赛启幕：哈佛校友JACOB深度解析比特币去中心化稳定币BTCD

Core Insights - The "Shanghaicity Blockchain Industry Application Labor and Skills Competition" was launched on September 29, 2025, focusing on the application of blockchain technology and talent cultivation [2] - Jacob, co-founder of the new Bretton system incubated at Harvard, highlighted the potential of Bitcoin-backed stablecoin BTCD for decentralized cross-border settlements [2][4] Group 1: Project Overview - The PG Protocol project, driven by 50% BTC hash rate, aims to establish a decentralized global trade finance infrastructure using a dual-token model (PGA/NBW) [4] - The project leverages Bitcoin's "super-sovereign" attributes to provide efficient and secure cross-border settlement solutions, transitioning Web3 and DeFi from concept to practical application [4] Group 2: BTCD Advantages - BTCD, a Bitcoin-backed stablecoin, has three core advantages: 1. Differentiated positioning: Pegged to 1 USD with Bitcoin as reserve, contrasting with USDT/USDC and DAI [5] 2. Technical robustness: 1 BTC can mint 40% (with FIST enhanced collateral up to 65%) equivalent BTCD, featuring security mechanisms like 90-day lock to prevent runs and zero-knowledge proofs [5] 3. Practical implementation: Supports multiple exchange channels and integrates wallet SDK and ERP interfaces for low-cost enterprise access [5] Group 3: Market Impact - BTCD is positioned as a practical token for enterprise-level payments, aiming to reduce reliance on the US dollar and lead global trade settlement transformation [7] - The competition aims to promote blockchain applications in governance and finance, with "Shanghaicity" as a national blockchain application demonstration zone experiencing explosive industrial growth [7][9] Group 4: Competition Significance - Jacob's insights provided an international perspective to the competition, making BTCD's technological pathway and application prospects a significant case for promoting blockchain usage through competitive events [9]
