Explore a comprehensive analysis of round optimal blind signatures in the standard model presented at Crypto 2011. Delve into applications, security models, known constructions, and potential challenges faced by both signers and users. Examine the protocol's development, including enforcing correct behavior and addressing unforgeability concerns. Investigate the relationship to FS[10] and consider open problems in this cryptographic field.
