However, existing schemes suffer from rapidly expanding ledgers caused by authentication data structures and fail to strike a balance between permission supervision and redaction efficiency. In this paper, we propose a novel verifiable and redactable blockchain scheme that introduces a dual-level authentication architecture to achieve lightweight storage and permission supervision. To this end, we first design a dual-level authentication data structure that appends all blocks to a constant-size global tag, while supporting verifiable redaction and query over on-chain data. Likewise, we introduce a dual-level chameleon hash structure, which not only employs committee members holding sub-keys to redact on-chain data but also enables the certificate authority to use the master key to correct malicious redactions executed by corrupted committee members. Furthermore, we propose an efficient auditing protocol to enhance the integrity and consistency of the blockchain ledger during the process of synchronous circulation. Finally, both security analysis and performance evaluation prove that the proposed scheme is practical.<\/jats:p>","DOI":"10.3390\/info17020176","type":"journal-article","created":{"date-parts":[[2026,2,9]],"date-time":"2026-02-09T16:13:32Z","timestamp":1770653612000},"page":"176","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["A Verifiable and Redactable Blockchain with Lightweight Storage and Permission Supervision"],"prefix":"10.3390","volume":"17","author":[{"given":"Meixia","family":"Miao","sequence":"first","affiliation":[{"name":"School of Cyberspace Security, Xi\u2019an University of Posts and Telecommunications, Xi\u2019an 710121, China"},{"name":"Guangdong Key Laboratory of Blockchain Security, Guangzhou University, Guangzhou 510006, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xueyi","family":"Yang","sequence":"additional","affiliation":[{"name":"School of Cyberspace Security, Xi\u2019an University of Posts and Telecommunications, Xi\u2019an 710121, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0286-7973","authenticated-orcid":false,"given":"Jianghong","family":"Wei","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Mathematical Engineering and Advanced Computing, Zhengzhou 450001, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9775-695X","authenticated-orcid":false,"given":"Guohua","family":"Tian","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Integrated Service Networks (ISN), Xidian University, Xi\u2019an 710126, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1562-5105","authenticated-orcid":false,"given":"Willy","family":"Susilo","sequence":"additional","affiliation":[{"name":"Institute of Cybersecurity and Cryptology, University of Wollongong, Wollongong, NSW 2522, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,2,9]]},"reference":[{"key":"ref_1","unstructured":"Nakamoto, S.
