Mutable transactions will make a fraction of all blockchain transactions, but will be a necessity to meet the needs of privacy regulations, such as the General Data Protection Regulation (GDPR). The state-of-the-art rewriting approaches have several shortcomings, such as lack of user anonymity, inefficiency, and absence of revocation mechanisms for entities authorized to mutate transactions. To address this challenge we present\n                    <jats:inline-formula content-type=\"math\/tex\">\n                      <jats:tex-math notation=\"LaTeX\" version=\"MathJax\">\\(\\mathsf{ReTRACe}\\)<\/jats:tex-math>\n                    <\/jats:inline-formula>\n                    , an efficient framework for blockchain rewrites.\n                    <jats:inline-formula content-type=\"math\/tex\">\n                      <jats:tex-math notation=\"LaTeX\" version=\"MathJax\">\\(\\mathsf{ReTRACe}\\)<\/jats:tex-math>\n                    <\/jats:inline-formula>\n                    is designed by composing a revocable chameleon hash scheme with an ephemeral trapdoor, a revocable fast attribute based encryption scheme, and a dynamic group signature scheme.
