Does blockchain refund money?

If you received a phone call from someone claiming to be a Blockchain employee, it is likely a scam . We would never initiate a call via phone. If an email was sent to your spam/junk folder, then please verify the real sender of the email by looking at the email’s headers.

You can verify your email by clicking the button within the email, or you can verify your email later from within the Security section . There, you can request a verification code to be sent to your email, or you can change the email address associated with your wallet.

No, we’re unable to cancel or reverse your transaction . Even many advanced cryptocurrency users can recall an incident when they failed to double-check their transaction details and they accidentally sent funds to the wrong recipient, or sent the wrong amount.

The redundancy of blockchains makes them hard to scale . Every device in your network must have a copy of every transaction made. That means hundreds of copies of the same data! It requires massive storage, and the bigger the blockchain, the more power the nodes need to process everything.
