S(3)Computing requires distributed computing performed by social network platform has high scalability and security. Protocol models meeting the requirements of S(3)Computing not only ensure the correctness and robustness of distributed computing, but also reduce risks introduced by involvement of nodes with low reputation in computing. These models safeguard the data collections and computations performed on platform of teacher's learning community for social researches. This paper constructs a protocol model entitled which adapts platform of teacher's learning community and meets the requirements of S(3)Computing. This protocol model is the key step of implementing distributed computations on learning community platform.
