Kialara is a ‘signature series’ of complex physical Bitcoins created by artist Maxfield Wyatt Mellenbruch. While they consist of a coin with a private key hidden under a hologram, they have little else in common with the conventional physical crypto-currency format. One inherent danger with the hologram system is that it may technically be possible to inject a special chemical underneath the hologram allowing it to be temporarily removed by gentle peeling, leaving no obvious physical sign of doing so. This is no concern for Kialara coins, as the edges of the hologram are rendered inaccessible by a piece of metal bolted with specially treated screws. The head of each screw is drilled smooth to disallow unscrewing, and the bolts are treated with a special adhesive called Loctite RED which makes undoing them impossible unless heated to over 500 degrees Fahrenheit. This means that to access the private key, the hologram must be cut or torn instead of peeled. In addition, there is still an added layer of security: the entire coin is encased in a metal and glass holder, which has no way of being opened without violently smashing the glass. As for the private key, a special coating protects it against damage from any light, water, and gases. A Kialara physical Bitcoin is made to endure for generations. While these pieces are certainly functional wallets, their primary purpose is artistic. Mr. Mellenbruch considers the public and private keys to be a unique ‘medium’ in his art.

With Kialara, Max collaborated with HAVEN, an initiative that builds ‘functioning beehive sculptures’ in urban areas to provide wild honeybees with a safe sanctuary. Donating 10 USD per order to the project, he raised 4,750 USD in just a few months.
