CBA® Markets

Joe Muczka Jr.

6 original works (2011–2023) with CBA® certificates of authenticity inscribed on Bitcoin.

CBA® (Certified Bitcoin Asset) is a native Bitcoin Layer 1 inscription on a satoshi (via Ordinals) that certifies the provenance of a real-world or digital artwork. It is immutable and acts as a legitimization layer for Real World Assets (RWA). A CBA® is a certificate of authenticity: the certificate body itself is inscribed on Bitcoin, so it cannot be rewritten, deleted or censored, and anyone can read it back from a Bitcoin node without an account and without our permission.
