BGG, the Biding Dog, is a practitioner of on-chain anonymous tipping culture. By organizing mutual aid communities and combining community activities, consulting services, and developing on-chain contract products, it addresses issues such as difficulty in trust, lack of platforms, no methods, lack of confidence, privacy concerns, and absence of useful tools among blockchain enthusiast groups. Based on the characteristics of blockchain networks and communities, BGG can offer richer business models and ecological patterns.
