Litecoin future price analysis
The key is one of created by Holdhus to authenticate individual artworks over the course of his future artistic career. Exposing it in this way depicts the anxieties of both the artworld and cryptoculture and allows the viewer to reflect on their interaction. To explain why will require us to situate both the artwork and its materials within the history of art and encryption. The re-emergence of cryptography as a popular pursuit in the Nineteenth Century starts with a link between code and art.
Cryptography and deciphering were popularized by the American author Edgar Allen Poe, who later created the cryptographic literary form of the detective story. Poe is a similarly liminal figure to mediaeval cryptographers such as Johannes Trithemius in his combining of cryptography, investigation, and spiritualism in literature and in practice.
Poe held codebreaking competitions in newspapers and challenged readers to send them unbreakable codes. His writings on cryptography were required reading in the American intelligence community up to the early Twentieth Century. Further reflecting the Mediaeval relationship between cryptography and the occult encryption and occultation , Poe was a popular subject for spirit mediumship after his death and for some time his most popular work was posthumous.
Contemporary cryptography starts not with the codebreaking conflicts of the Second World War which for the most part just automated earlier systems but with the discovery of Public Key Cryptography PKC at first secretly in the UK and then publicly in the USA in the s. PKC allows messages to be encrypted using a separate key that cannot be used to decrypt it, which can therefore be made public.
Like the association of cryptography with the occult, this link between cryptography and trade goes back to the Renaissance. The relationship between mathematics and cryptography stretches back even further, to earlier Arab herpetologists. In previous eras, art had a similar relationship with mathematics as part of its self-image, for example in its geometries and colour theories, but Contemporary Art has a mathematics taboo.
There is no reason why this should continue to be the case — public key cryptography can provide form, subject and content for art. The points, lines and planes found in private and public keys and in the operations of encryption and decryption relate to mathematics and geometry in art. The mathematics of ratio and projection were common to Renaissance trade and to perspective. PKC has become contemporary trade math, although it has not yet led to an equivalent of perspective in art.
While mathematics is a conceptual resource that strangely elicits disdain or hostility in the digital financialized era of contemporary art, Sol LeWitt showed that it can be used in a critical way. The textual and visual representations of these mathematical objects — long strings of hexadecimal or Base58 digits, QR codes and ASCII art — have both their own innate and contingent aesthetics.
These aesthetics can evoke the worlds of communication, commerce and espionage as they are determined in contemporary life by cryptography and its absences backdoors, sidechannel attacks, quantum computing, etc.
Or the qualities and experiences of secrets, value, identity and trust or, again, its absence that they relate to. These are more concrete subjects than the instrumentalized Platonic realm of cryptographic mathematics, but they flow from them.
Those phenomena include the economy, whether conventional finance or cryptocurrency, politics, whether secrecy or hacks of state actors and cypherpunk provocateurs, and the questions of identity, authenticity and permission that PKC and cryptographic hashing are applied to in networked media and culture.
The presence of cryptography or its imagery in a piece of art need not function as any of these — apart from anything else an artwork can always fail. It may end up as a mess or as kitsh. These are modes of usually unintentional and visible inauthenticity, in contrast to the intentional but hidden inauthenticity of fakes. The fake is a problem for the art market and for the artistic and scholarly reputations that provide its capital.
Catalogues raisonnes are meant to tackle the problem of the fake but the risks of authenticity and value that they carry make them a site of market and scholarly anxiety. This can have a chilling effect on both scholarship and on markets. This can take the form of a digital file, a radio frequency tag, or a QR code or print-out of the signature sealed from sight and attached to a physical work.
One of the stronger non-monetary uses of blockchains is to publicly record and timestamp such signatures. In particular this makes it impossible to claim that posthumously released works were released by the artist during their lifetime. This illustrates a way that the fake and its problems of identity authenticity and value relates to the double-spending problem that cryptocurrency solves.
Lars Holdhus is using non-blockchain PKC to authenticate and to limit the number of works they can produce. In 2CE6 the operational security of this strategy is deliberately broken. The first rule of PKC is never to give out your private key.
Doing so allows anyone to read your messages or steal your Bitcoins. It de-occults the information that would guarantee its authenticity and thereby its value in order to become or unfold as an artwork, constructing its cultural and economic value by an apparent act of destroying it and critiquing its materials in the process.
Looking for a precedent for this leads to net. The relationship between secrecy, artistic identity, authenticity and transparency has a precedent in the art of the Guerilla Girls. In 2CE6, Holdhus restores the historical link between the contents of art and of cryptography.
The contemporary occult of the opacity of the art market, the security of value in trade, and their mathematics exist together cryptographically and artistically in it in a mutually problematizing, and therefore realistic, way. Cryptography functions here as artistic form, subject and content. When a public key is exposed, it is the end of its usefulness, it is dead.
Bitcoin is the leading cryptographic digital currency. Created in by the now possibly unmasked hacker Satoshi Nakamoto, it polarizes opinion. Others criticise Bitcoin, often savagely, for the same reasons and for what they perceive as its technical and social failings. But Bitcoin is interesting in ways that go beyond the concerns of its most vocal proponents and detractors.
Transactions in Bitcoin use cryptographic signatures rather than names or emails as the identities of the sender and receiver. All of this means that Bitcoin is a massively distributed system for asserting identity, existence, and truth, for values of those concepts that are outsourced to a community of mathematical proxies. The blockchain is essentially a time-stamped record of information that anyone can add to in order to prove that a particular piece of data existed at a particular time.
This has applications beyond finance, with examples of new systems for blogging, contracts, corporations and Internet Domain Name services all being based on the block chain system. In many ways it is the blockchain and these applications of it that is the most exciting part of Bitcoin. Money, cryptography the making and breaking of codes and alternative currencies all have long and often intertwined histories. Renaissance banks used secret codes to secure messages sent between city-states.
The first cryptographic digital currency was Digicash, from Linden Dollars, the virtual currency used in the Second Life online virtual reality environment, were used in USD,, of economic activity in Bitcoin has encouraged a debate about what money is, what money is for, and how money should work, indeed its production, use, and successors have embodied that debate. But these are implementation details, and newer cryptocurrencies and national cryptocurrencies address them.
Post financial crisis, cryptocurrency with all its possibilities and contradictions is a lightning rod for the social imagination. And this includes art. Coinfest in Vancouver featured examples of artists using Bitcoin. Buskers performing at the event could be tipped in Bitcoins, graffitti and mixed-media art being exhibited could be bought with Bitcoins. And in the computer lab at the venue each desktop PC displayed a piece of net art with a Bitcoin theme.
It includes art depicting bitcoins, art visualizing wealth in terms of bitcoins, and work that evokes the operation of Bitcoin-like cryptocurrency. The economy is like that. Coiyes, Bartcoins, and Radeon graphics cards intrude, presumably as they matched the search used to find buttcoin images.
Visual Vaporwave, the kind of transubstantiation of kitsch that art is meant to do. Digitisation, sustenance and symbolism combine here much as they do in Bitcoin. The net wealth of wealth on the net. Its an impressionistic take on cryptocurrency and the environment in which it exists. The comparison between this energy footprint and that of fiat currency ATMs, chip and pin readers, and other elements of the global banking system probably compares to the relationship depicted here.
The Euro is a political instrument as much as a financial one, and its crisis has been another factor driving interest in alternative currencies, including Bitcoin. I found it aesthetically and conceptually opaque, although a very effective composition. The ability to curate such a show online and present it as part of a wider cultural event marks a moment where the widespread availability of Internet access, Web 2.
The recurrent themes, of pennies from heaven, ironic digital kitsch, glitchy compression artefacts, and potlatch, feel both appropriate and effective in visually communicating and critiquing the technical and social complexities of cryptocurrency in the age of austerity. Bitcoin has caught the attention of the public, government, criminals, and artists. It is both an expression of the economic imaginary and a genuinely novel means of networked communication. This makes an unusual subject for art, whether celebratory or critical.
Even the most ironic celebrations of Bitcoin in art are depictions of a network protocol, or a deflationary electronic currency. It is the art of a heresy rather than a hegemony, of a moment of technological, social and aesthetic possibility.
A thought-provoking, illuminating and often fun collection of work of a uniformly high standard that is nonetheless technically and aesthetically diverse can be presented online and off as part of a wider cultural event.
