Second, the current development of the \", \"2301.00479v2/p2\": \"a distributed database is controversial. Second, the current development of the blockchain community reveals a taxonomy of 7 categories, namely, privacy and security, scalability, decentralization, applicability, governance and regulation, system design, and cross-chain interoperability. Both research and practice are more centered around the first category of privacy and security and the fourth category of applicability.

Additionally, we propose\", \"2601.01239v1/p2\": \" humans and Automatic Speech Recognition (ASR) systems.
