    One of the top C++ libraries for generating random numbers in blockchain applications is Crypto++ (CryptoPP). It provides a wide range of cryptographic algorithms, including random number generation. Crypto++ is highly regarded for its security and performance. It offers various random number generators, such as the AutoSeededRandomPool, which uses system-provided entropy sources to generate random numbers. This library is widely used in blockchain projects due to its reliability and extensive documentation.
