The Amsterdam Lights Festival is world-famous, and tourists from all around the globe flock to the city to see the beautiful architecture and canals lit up by innovative artists that choose light as their medium. This year, an interesting work of art has been on display on one of Amsterdam’s most famous streets: the Herengracht. Although some have been puzzled and confused, it would appear that the artwork is actually Bitcoin code.

Dutch artist Frederike Top is behind the artwork, which is called “Code”. Top is 37, and has been very conscious of where she placed her artwork. Specifically, the art is displayed over a former bank building. The website explains that the artist is clearly making a statement about how blockchain threatens banks, stating:

Central control is no longer needed for digital transactions as opposed to the traditional financial world. Cryptocurrency is a real threat for governments and banks as Top highlights in her installation by positioning it in front of the enormous, ‘closed’ former bank building.”

The BTC address, interestingly enough, actually includes the word “bank”. For those wondering about the purpose of the Bitcoin address – it is actually a charitable one. Those who send money to the address are donating to Huis van de Tjid, a foundation that aids elderly individuals suffering from dementia.

Amsterdam is quite Bitcoin-friendly. In fact, earlier this year, the House of Nakomoto was opened in the city, which improvises somewhat like a Bitcoin museum, and serves to inform visitors about cryptocurrency who might not be familiar with the space. It also houses a retail store that sells cryptocurrency-related products, as well. The name is an obvious reference to Satoshi Nakomoto, the anonymous inventor of Bitcoin.

Top normally works with lamps and furniture, and her artwork is often seen as “playful” and requires more interaction than many of her peers’ work. “Code” will be on display until January 20, 2019.
