Về ARPA Chain (ERC 20) (ARPA)
ARPA is a secure multi-party computation network relying on smart contracts and information exchange among multiple blockchain networks, and is a type of Layer 2 solution. ARPA adopts secret sharing, somewhat homomorphic encryption, Beaver circuit randomization technology, etc. to perform multi-party addition and multiplication equations of cyphertexts, and realize more complex computational logic, which is aimed to achieve the Turing complete computing power. However, in the current technological environment, there is still a gap of 1-2 orders of magnitude between the speed of secure multi-party computation and that of plaintext computation.
