In the embodiments of the present disclosure, the stereo network may include at least two heterogeneous block chain networks, for example, a super chain stereo network, and each block chain network may have different account system information. The account system information may include a cryptography family, which may include pseudo-random functions, elliptic curves, hash algorithms, signature algorithms, etc., and a mnemonic dictionary, which may include a language of the mnemonic and a thesaurus of the mnemonic. The cryptographic family in the embodiments of the present disclosure may employ National cryptographic Standards, NIST (National Institute of Standards and Technology ), standards, and the like.
