Proof Of Work Exhibit To Visualize Blockchain Technology

The The proof-of-work (PoW) system is a measure to prevent attacks to the blockchain network. It requires work and processing time from the requestor (computer). This protocol is in place to disallow spam on the blockchain network, deter other abuses such as double-spending, and confirm that a new block is found/formed. Ether is just one example of a coin that utilizes the PoW protocol. One important property of a block in Ethereum and many other crypto-ledgers is that the hash of the block must be smaller than some target value. The reason this is necessary is that, in a decentralized system, anyone can produce blocks, so in order to prevent the network from being flooded with blocks, and to provide a way of measuring how much consensus there is behind a particular version of the blockchain, it must in some way be hard to produce a block. Because hashes are pseudorandom, finding a block with a hash that has less than 64 bytes takes an average of 4.3 billion attempts. In all such systems, the target value self-adjusts so that on average one node in the network finds a block every N minutes (eg. N = 10 minutes for Bitcoin and 1 minute for Ethereum).

“>Proof of Work” debuts on Friday, September 7, in the city’s Schinkel Pavillon, an institution dedicated to contemporary sculpture, installation, and media art. Unlike other art exhibits in the space, though, this one is focused exclusively on blockchain and 

According to information shared with ETHNews, the exhibit will feature “artwork made by crypto builders, crypto experiments built by artists, and paintings and drawings that resonate with cryptocurrency but predate the invention of The agreement among all nodes in the network about the state of the Ethereum network.

Denny is known in the art world for his blockchain-centric creations. His work “Blockchain Future States” debuted at New York’s Petzel Gallery in 2016, but it recently appeared at Karlsruhe, Germany’s ZKM Center for Art and Media in the “Open Codes” exhibition, which attempts to explain the complexity of digital codes.

One of the 

“>key components of the upcoming “Proof of Work” exhibit will be a new piece titled “Chaos Machine” created by Distributed Gallery, a blockchain-focused art gallery. The artwork includes a jukebox that, according to the gallery crew, “burn[s] banknotes and turn[s] them into cryptocurrency by playing music.” The machine has been called the “Exterminating Angel” because it “shows the vacuity of another object [the banknote] it intends to destroy,” the team said.

Additionally, Distributed Gallery recently asked its Twitter followers to provide suggestions for songs that the jukebox should play while burning banknotes. Although individuals suggested tracks from artists like Pink Floyd, AC/DC, and John Cage, the CryptoKitties team suggested the sound of a cat purring. The gallery responded:

Besides “Chaos Machine,” the exhibit will include artwork from at least 19 artists or groups, including Rob Myers, Kei Kreutler, and the CryptoKitties team. In fact, digital canvases of the pixel-based cats were recently included in the “Open Codes” exhibition at the ZKM Center.

“Proof of Work” will be available at the Schinkel Pavillon for individuals’ viewing pleasure until December 21.
