QR codes are a type of two-dimensional barcode that can be read by smartphones and other devices. They are often used to provide quick and easy access to websites or other online content.

However, QR codes are no longer accepted on the blockchain or Coinbase. This is because QR codes can be easily hacked or spoofed. For example, a hacker could create a fake QR code that looks identical to the real thing. When someone scans the fake QR code, they would be taken to a malicious website instead of the intended website.

QR codes are also difficult to scan accurately. This can lead to users being taken to the wrong website or even to a malicious website. For these reasons, QR codes are no longer accepted on the blockchain or Coinbase.
