What are bridge coins?
Could you please elaborate on the concept of "bridge coins" in the cryptocurrency landscape? I'm curious to understand how they function and why they are important. Specifically, I'm wondering about their role in facilitating transactions between different blockchain networks, if they involve any specific technology or protocols, and whether they present any unique challenges or opportunities for investors and developers. Additionally, I'd like to know if bridge coins have gained significant traction in the industry and if there are any noteworthy examples of their implementation. Thank you for your insights on this topic.
