Abstract: Running behind new technologies is increasingly becoming a non-circumventable requirement for organisms’ survival. This is not only a strategy to gain a competitive advantage in the market but it is a determinant key for their continuity and persistence. The Blockchain is at the heart of this technological revolution for which transparency, accessibility to the public and the sense of sharing are fundamental properties of its design. Despite its importance, leveraging this technology in an ethical and secure manner by ensuring confidentiality and privacy is a top concern. Through this work, we try to design a new approach to validate transactions within the Blockchain. Entitled "Protocol for Partial Confidentiality & Transparency PPCT", this new protocol makes possible to seek a compromise between the two requirements: Confidentiality & Transparency. It allows introducing a new notion of confidentiality that we have named partial confidentiality. Subsequently, it applies it on the transactions exchanged while ensuring the process of their validations by the different nodes of the Blockchain. In addition, and through the use of hashing and digital signature functions, this protocol also ensures integrity and authentication within its validation process. To present this work, we will first discuss the state of the art on the different current privacy approaches and our motivation behind this work. Then we will explain more about the different stages of this process, its benefits and areas for improvement.
