2022 Redactable Blockchain with K-Time Controllable Editing
abstract
Considering the immutability of traditional blockchain restricts the governance and regulation of sensitive data on chain, this paper proposes a redactable blockchain scheme with k-time controllable cheating editing (CCE-RB for short). In the CCE-RB scheme, the regulator requires editors to generate vector commitments, so as to set the number of times each editor’s editing permissions can be used. The editor needs to open each component of the vector commitment successively before each editor prove that he/she has enough number of times of editing. The regulator has the right to revoke the editor’s editing permission when the editor’s editing times are exhausted or cheating editing behavior occurs, thus realizing the revocability of the editor’s editing permission. In a word, CCE-RB achieves regulation of whole editing process by block editability, controllability of editing times and revocability of editing permissions. By comparing and analyzing related schemes, the experiment results show that CCE-RB scheme has good efficiency.
