The digital signature is well recognized as a prominent use of asymmetrickey cryptography, effectively addressing the limitations associated with handwritten signatures through the preservation of data integrity.The digital signature is characterized by the involvement of two distinct parties.In practical contexts, it is not uncommon for many parties to affix their signatures to a single document.To mitigate the risk of fraudulent individuals submitting signed papers under false identities, the implementation of digital certificates and certificate authorities (CAs) has been introduced.The previous approach introduces a novel challenge arising from the limited duration of digital signature validation.In contrast, blockchain technology, which was introduced by Satoshi Nakamoto in 2008, has had a significant impact on the field of digital archiving.Therefore, this paper explores an alternative application of blockchain technology for the purpose of preserving previously signed documents, enabling their validation over an extended duration.The test results indicate that the suggested technique has effectively fulfilled the functional requirements of a multisignature system, encompassing data integration, non-repudiation, and traceability.
