The potential of blockchain is limitless. Capturing Whale will forge ahead resolutely, bringing together global top-tier talent and innovative forces to continuously push the boundaries of innovation, jointly exploring and realizing the future of blockchain cross-chain赛道!
In the blockchain field, cross-chain technology addresses the issue of isolated ecosystems by enabling interoperability among different blockchains. This innovation holds significant potential and commercial value, making it one of the most crucial advancements in blockchain. Cross-chain technology facilitates the free flow of assets and data, enabling more efficient value exchange and information sharing. Therefore, learning about cross-chain technology is essential.
This series of cross-chain public lectures is led by Whaler and co-organized by Peking University Blockchain Association, talent recruitment platform Talentre, full-stack cross-chain project Map Protocol, and blockchain media ChainCatcher. The program follows a Saturday (educational) + Sunday (project-focused) format, combining theory with real-world case studies to meet practical business needs. Anchored in career development, this initiative aims to build the highest-quality and most comprehensive cross-chain curriculum through community-driven, public-benefit collaboration. The event has received co-building support from over 50 partners, including university blockchain associations, blockchain media, projects, institutions, DAOs, and communities.
The full course spans 10 weeks with 20 sessions, launching every Saturday and Sunday at 16:00 (UTC+8). Lectures will be live-streamed simultaneously on Bilibili and YouTube. The complete program includes public lectures, self-assessment quizzes, product interactions, and a full job recruitment cycle. Entirely free of charge, this public course welcomes all students interested in cross-chain technology and its ecosystem.
The potential of blockchain is limitless. Whaler remains committed to moving forward, gathering top global talent and innovative forces, continuously pushing boundaries, and collectively exploring and shaping the future of the blockchain cross-chain landscape!
Introduction to the Cross-Chain Landscape & Technology
The significance of the cross-chain sector lies in solving fragmentation and isolation within the blockchain ecosystem. Currently, technical barriers and interoperability challenges between different blockchain networks restrict the industry's growth potential. Cross-chain technology overcomes these limitations by enabling seamless connectivity and asset transfer across disparate blockchains, promoting the free circulation of digital assets and value, thereby enhancing the overall efficiency and scalability of the blockchain ecosystem.
The emergence of the cross-chain sector helps build a more stable, secure, and efficient blockchain ecosystem, holding profound implications for advancing widespread blockchain adoption and digital transformation. Cross-chain technology serves as a key driver for blockchain innovation and real-world application. Traditionally, blockchain networks operate independently, unable to directly interact with one another. Cross-chain technology overcomes this barrier by introducing specific protocols, bridging mechanisms, or middleware layers, enabling information and asset flows between different blockchains. At its core, cross-chain technology establishes a mechanism allowing distinct blockchain networks to trust each other and communicate securely, thus enabling cooperation, asset sharing, and data exchange.

Cross-chain technology possesses immense developmental potential and commercial value, representing one of the most critical innovations in the blockchain domain. It enables the free movement of assets and data, facilitating more efficient value exchange and information sharing. Through cross-chain capabilities, users and enterprises can leverage the unique features and advantages of different blockchains to expand their operations, reduce transaction costs, enhance interoperability, and foster innovation and collaboration.
The development of the cross-chain sector plays an irreplaceable role in improving the overall efficiency and sustainability of the blockchain industry. By enabling the free flow of digital assets, cross-chain technology unlocks vast potential and opportunities for blockchain applications. Thus, understanding cross-chain technology is essential, whether for staying current with cutting-edge developments or planning one’s career path.
