Polkadot parachains can now choose to add Chainlink price feeds to their runtime.
Polkadot and Chainlink have announced the release of Chainlink’s Price Feeds as a module, or “pallet” in Polkadot terminology, for the Substrate blockchain framework.
The release means that any project building on the Substrate framework — which includes Polkadot and Kusama parachains, as well as independent blockchains — can integrate Chainlink oracles through a simplified library.
The announcement comes as the latest result of a long-standing collaboration between Chainlink and Polkadot, now offering a tangible product that can enable a number of DeFi-centric use cases on Polkadot.
The integration as a Substrate pallet means that it is up to each individual parachain to integrate and enable Chainlink oracles. This is a significant change from the architecture used on Ethereum, where Chainlink nodes regularly publish price data on each block, which smart contracts can then choose to reference or ignore.
On Polkadot, the more flexible design means that parachains that do not need Chainlink data won’t need to devote any blockchain space to it. On individual parachains, however, the end result may look similar to Ethereum. Peter Mauric, head of communications at Parity Technologies, compared the situation to “as if Chainlink were integrated as an opcode on Ethereum.”
The complete Chainlink integration is likely to be welcome news for DeFi-centric parachains like Moonbeam, Equilibrium or Acala, especially from the perspective of introducing Ethereum projects to Polkadot. However, there is likely to be additional development work required to adapt the Chainlink pallet for use with smart contracts.
Chainlink is used by a number of DeFi projects on Ethereum to read external market data — a critical necessity for lending protocols, in particular. The project recently began a shift toward focusing on more than just price data, a pivot that comes at the heels of introducing the Off-Chain Reporting architecture.
Its been a heady few weeks for commerce and art.
Surely a revolution is afoot and were too mired in the hot mess to see it right.
With that proviso, here are two notes from the front lines.
NFTs are cutting-edge, digital art aint
Some folks say the non-fungible token (NFT) that allows a digital artwork to be possessed exclusively by a purchaser is traceable to the creation of Colored Coinsin 2012 or to CryptoPunks in 2017 even though the this market exploded just the other day.
A page from Jules Antoine LissajoussA Study of the Optical Representation of Sound Vibrations, 1957
But digital art (DA) itself has an older pedigree.
As early as 1857, the Frenchman, Jules Antoine Lissajous (18221880) published images of mathematically-designed Lissajous Figures by capturing lines created by sound harmonies with a camera. These figures had been identified 42 years earlier by the American, Nathaniel Bowditch (1773 -1838) its just that Bowditch didnt render them as pictures.
The first art piece fully recognized as computer-made, and hence, digital, was Oscillon 1 made in 1950 by the American computer scientist Ben Laposky (19142000). He called these pieces Oscillons or Electrical Compositions. They were Lissajous Figures of a complex type. A 1953 show of his work in Cherokee, Iowa designated them electronic abstractions.
Ben Laposky, Oscillon 45, 1952
Laposky inspired other digital artists, producing the mediums first major show in 1965, in Stuttgart, headlined by Frieder Nake (b. 1938) and the first museum show, Cybernetic Serendipity, at Londons Institute of Contemporary Arts three years later.
DAs emphasis on geometric abstraction piggy-backed on the worlds excitement for Pollock and the swarm of Abstract Expressionists roiling the cultural waters of that day. The optical gamesmanship and clean rendering of DA designs also lent momentum to early 1960s Op Art.
Op Art: Frank-Stella, Untitled, 1966
DAs entrancement with crisp linearity, geometry, and images categorized by number persists to this day.
Major digital art collections exist at the Whitney, MOMA, the Walker Art Center, and other juggernauts of the art world; and over a dozen museums dedicated to digital art now exist from Zurichs MuDa, to Tokyos Mori Museum of Digital Art, to the Center for Digital Art in LA.
NFT Pics: Easy on the Eyes, But not Museum-Ready
Beeple (Mike Winkelmann at beeple-crap.com the man who created the $69 million Everydays) said were witnessing The next chapter of art history.
New chapters of art history are written by artists making new art.
But this is a chapter being written by artists (and their advocates) making novel financial moves.
This is a new chapter in financial history.
Piero Manzoni, Artists Shit, 1961
Its true, Damien Hirst and others have performed financial acts as aesthetic ones. Artists have sold air, shit, and invisibility as conceptual advancements, but thats not whats happening this month.
When this art is attached to an NFT and sold for piles of crypto, its not showcased it as an artistic performance.
Heaps of new market fluidity are is being leveraged, but no fresh aesthetic concepts is are shaping the action.
As of this writing, the overwhelming majority of images moving into NFT collections for slag-heaps of Ethereum are more akin to 1950s paperback covers than the digital art productions that have migrated to museums and marquee galleries for years.
Beeple, Infinity and Beyond, 2015
Though its main inspiration is anime, computer games, and comic books, this NFT-drop will surely persist in the field of cultural reference for decades, and, I will confess, there IS an art-historical development here, but I dont think its the one Beeple is thinking of.
This moment is an A-bomb explosion in the larger fragmentation and recombination of kitsch and high art thats been going on for one long, bloody D-Day since Andy Warhols first art show in 1962.
We can point to Toulouse Lautrec (1864 -1901), Stuart Davis (1892 -1964), and handy Andy (1928 -1987) as the dudes who threw the first blow, but the master bomb-maker in todays fractured landscape is certainly Brian Donnelly (b. 1974), better known as the comic-figure maker, KAWS (. . . with apologies to Takashi Murakami).
KAWS, Small Lies, 2020
Its true, this could be a new eruption of low-brow taste (as folks have said of the emergence of KAWs and Warhol), but I dont think thats the case.
Theres just a whole tuna school of new-money millionaires splashing around the planet who are used to Neuromancer–style imagery and theyre buying whatever they like.
Its no art revolution.
Its no change in taste.
Its just the emergence of some delightfully new destinations for loads of disposable income.
That said, Im confident that a cultural counterweight of historical artists will be joining marquee first-adopters like Kenny Scharf in the NFT market any minute now.
At the rate things are evolving, Ill bet my bottom Bitcoin that as these wild, explosive, and strangely historical weeks round out the month, blockchain moneywill begin to chase higher-grade art commodities, just as it now chases CryptoKitties, video snippets, and original tweets.
Ethereum options traders are placing big bets on an ETH rally in June as EIP1559 approaches.
As Cointelegraph previously reported on March 29, Visa will allow its partners to use USDC on the Ethereum blockchain network to settle transactions.
Since then, the interest in Ethereum across both futures and options markets is seeing an uptick, with the former approaching $7 billion, the highest in over a month.
The options market for Ethereum is particularly optimistic
According to Cantering Clark, a cryptocurrency trader and analyst, the Ethereum options market shows big bets heading into June.
The strike price with the highest open interest is $3,200. Although this does not necessarily mean that there is a high probability of ETH hitting $3,200, it indicates that there is significant interest at that price level. The trader said:
“Is it the start of $ETH season? Options market making some big bets into June. 3200 strike has a bullseye on it.”
While there could be multiple reasons why traders might be anticipating ETH to surpass $3,000 by June, one of the biggest factors is the much-anticipated EIP1559 upgrade.
EIP1559 is set to go live in July 2021, which would overhaul the existing fee structure of the Ethereum blockchain.
Simply put, the proposal burns fees that are paid in ETH rather than paying miners, which proponents say should stabilize fees for transacting on the Ethereum blockchain. As Cointelegraph reported, the cost of using the blockchain rose 77% over the past few days in line with a 31% increase in the price of Ether.
EIP1559 essentially burns some of the ETH paid for transacting, which should reduce the circulating supply of ETH and hence put upward pressure on its value.
Since a lot of options targeting the June strike price would expire right before the EIP1559 implementation, it means traders are expecting a rally going into the implementation phase.
Massive ETH outflows are also being spotted
Meanwhile, Ki Young Ju, the CEO at CryptoQuant, points out that Ethereum has been seeing massive exchange outflows in the past few days.
Earlier this week, Ki noted that 400,000 ETH left Coinbase, which could signal a spike in institutional interest in ETH. He said:
“400k $ETH flowed out from Coinbase a few days ago. Speculative guess, institutions are now buying $ETH.”
Outflows often signal strong accumulation by institutions and high-net-worth individuals because when whales buy cryptocurrencies on an exchange, they typically move their holdings to self-hosted wallets.
Hence, the view is generally optimistic for Ethereum over the next few months because positive on-chain data is supplementing a strong fundamental catalyst in EIP1559.
Atop this, the number of active addresses are continuing to increase with exchange reserves consistently declining, indicating rising user activity and demand for ETH.
Glassnode also reported that the number of non-zero addresses hit a new high, suggesting that user activity is on the rise.
Researchers at Glassnode said:
“Ethereum $ETH Number of Non-Zero Addresses just reached an ATH of 56,543,380”
