What is the Blockchain?
Accredible uses the Bitcoin Blockchain to store an immutable record of credentials. The Blockchain is an incorruptible digital ledger of bitcoin transactions that can be used to securely record virtually everything 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.
What is a Blockchain Credential? and How Does it Prevent Credential Fraud?
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.
When you verify a Blockchain Credential, Accredible checks the blockchain for a record of this credential being issued - no one can pretend that their credential is actually on the blockchain when it isn't. We will show the result of the verification below the credential.
What Does "Some information has changed" Mean?
Sometimes, after creating a credential, information will need to be changed to reflect the course, or name misspellings. If you are seeing this warning, the credential has been verified by the blockchain and is trustworthy, but some of the information has changed and no longer perfectly matches the blockchain's record.
Here are some items that could have changed, and what they mean:
Recipient Name has been updated - the recipient's name was likely misspelled or displayed an alternate name when the credential was initially issued. The recipient has to submit an approval request to the issuer of the credential, who screens it and approves or denies the request based on the likelihood that an honest mistake was made. This is a common correction of the credential information that can happen after the credential is recorded to the blockchain.
Recipient Email has been updated - Accredible uses the recipient's email address to track the owner of the credential. Sometimes, this email is a work or a shared email that should not be in permanent possession of the credential, so the recipient makes a request to change the email that owns the credential. In order to make this change, Accredible verifies that the recipient is the owner of both email addresses.
Credential Name has been updated - If the issuer of the credential changes the name of the credential after issuing (for example: 'Example Course Name' to 'Example Course - Level I'), this will not exactly match the blockchain record, but the issuer of the credential has decided to make this update.
Credential Description has been updated - Likewise, the issuer can make updates to the description of a credential after issuing. This might reflect changes to a curriculum over time that may or may not be reflected by the credential holder. In this case, the issuer has decided that these changes are not significant enough to warrant invalidating previous credentials.
