Accredible uses the Bitcoin Blockchain to store an incorruptible record of credentials.
The Blockchain is an incorruptible digital ledger of bitcoin transactions that can be used to securely record virtually anything of value. Anything that is written to the Blockchain can't be altered in the future by any party because of the complexity of the blockchain. When an Accredible credential is issued and recorded to the Blockchain, the record of the credential is written into the list of Blockchain transactions. Because the Blockchain is public anyone can verify that the credential was recorded at the correct time, validating that information you see at Accredible is correct. More information on Blockchain Credentials.
When the issuer of a credential decides to issue a Blockchain Credential, Accredible makes an encrypted record of who created the credential, who received it, and when it was created, right onto the blockchain. This means that every blockchain credential is incredibly secure.
On the credential view, blockchain credentials will show the section of the Blockchain that they were recorded to (Blockchain ID) as an indicator of the real information you can verify.
When you click 'VERIFY' on the credential view, Accredible will give you more information about the Blockchain record of the credential and how anyone can verify it's legitimacy.
Credentials written to the Blockchain before April 2019 will have a slightly different display:
On the 'Verification' page, you will be given a link to 'Download Blockchain Proof File'. This will immediately download a record of what was recorded to the Blockchain. You can upload this to an independent website to verify that this record was written to the Blockchain. A successful result means that the proof file tied to the Accredible credential also exists independently on the Blockchain - meaning that the information is secure.
Note that the block ID on the proof message will match the one on the credential view! We've now verified (with a third-party) that the Blockchain record of the credential is correct.
Credentials written to the Blockchain before April 2019 can be verified by following our manual verification process: https://help.accredible.com/hc/en-us/articles/115005058985
