Abstract: The notion of Public Electronic Contract (PEC) Protocol is presented in this paper. In the idea, the PEC will be published on a public directory (of certain groups) and let all the members to review the true (raw) transaction information. Collection of information of PEC reflects more reliable facts of the market trends rather than merely depends on the data provided by certain agencies for estimation. The goal is to eliminate the opportunities for certain agencies to manipulate the data and persuade the investors to make inappropriate decisions on purchases or investments. A perfect open market with open facts should be established in the future. The PEC also contains the property of public witnesses so that the transactions will be more secure. In order to keep the protocol simple; its implementation is mainly based on RSA public key scheme.
