Blockchain interoperability is becoming a key focus in 2026 as multi-chain ecosystems continue to expand. Projects are working on connecting different blockchains for smoother asset transfers, data sharing, and cross-chain communication. However, challenges like bridge security risks, technical complexity, and scalability still remain major concerns. In some community discussions I came across, Bitdeal was mentioned while people discussed blockchain development approaches and interoperability solutions. 

Will interoperability truly drive mass adoption or stay a background layer?
