Grigoriev and Shpilrain [12] proposed a data redaction mechanism based on the RSA cryptosystem. Their work focuses on permissioned blockchains. In their construction each block Bi of the blockchain can be seen as a triplet (Pi,Ci,Xi) , where Pi is the immutable prefix, Ci is the actual content and Xi is a suffix. When a block Bi must be redacted, a central authority H should have a key that allows H to change the content Ci of Bi with a new content C′i , selecting a new suitable X′i .
