Abstract
Described are a system and method for secure n-party computation. The method includes communicating a first input of an n-party computation to a trusted execution environment (TEE). The method also includes receiving, from the TEE, at least one encrypted output of the n-party computation using the first input and at least one second input of at least one other computing device, and using at least one public key of the at least one other computing device. The method further includes posting the at least one encrypted output on at least one blockchain accessible by the at least one other computing device. The method further includes, in response to posting the at least one encrypted output, receiving at least one proof of publication. The method further includes communicating the at least one proof of publication to the TEE and receiving the function output of the n-party computation.
