Certification Data and Blockchain Minting

Irreversibility and Immutability

When you confirm the upload and minting of certification data on the OneChain blockchain, please be aware that this action is irreversible and the data becomes immutable on the blockchain. Once minted, data on the blockchain cannot be altered, deleted, or reversed. This is a fundamental characteristic of blockchain technology.

CertLedger cannot facilitate the removal or alteration of data on the blockchain, and users should exercise caution and due diligence before initiating the minting process.


You are solely responsible for the accuracy and completeness of the data you upload and mint on the blockchain. CertLedger does not have the capability to modify or reverse transactions on the blockchain, and we disclaim any liability for any consequences resulting from actions taken on the blockchain.
