Overview of the maturing blockchain and digital asset ecosystem, focusing heavily on regulatory developments, enterprise adoption, and core technical challenges. Specifically, one source details the UAE's Digital Dirham (CBDC) initiative as part of its Financial Infrastructure Transformation (FIT) programme, highlighting its use in cross-border payments like Project mBridge and its design considerations. Other documents examine the state of global crypto regulation in 2025, with a focus on comprehensive frameworks like the EU's MiCAR and shifts toward regulatory clarity in the US and other jurisdictions. Several texts discuss enterprise blockchain adoption, noting its maturity beyond hype for specific use cases like traceability, while also addressing roadblocks such as unclear ROI and integration complexities. Finally, a technical survey explores solutions for cross-chain interoperability and communication, discussing mechanisms like Simplified Payment Verification (SPV) and the critical property of atomicity.
