What is ZeroAlpha?

ZeroAlpha is an Always-on-Sale artwork marketplace where artists and philanthropists come together to make the world a better place, by working on the big global challenges of our time, such as climate change, world hunger or quality education.

What do you mean with "Efficient Art Market"?

Past century economics fostered the idea of efficient markets and despite the extensive effort taken (e.g. regulation and de-regulation), we can see insider trading, price manipulation and other fraudulent activity wherever we look. Artwork markets are especially inefficient, as it is stated throughout the scientific literature. ZeroAlpha solves this through the always available transparent sale-price and the incurred cost of the associated patronage, and therefore it is the first efficient artwork market on earth. You can't beat the market, hence "Zero" "Alpha".

What can be bought on ZeroAlpha?

You can buy digital artwork in the form of a 'Non-Fungible Token' (in short NFT) which can not be copied or taken from you, because it resides on a public blockchain.

What does Always-on-Sale mean?

All artworks on ZeroAlpha can be bought at any given time, hence it is Always-on-Sale. Every buyer has to specify the re-sale price when buying the artwork. This re-sale price does determine the patronage (also called Harberger Tax) payed to a non-profit organization the prospective collector can select from a list (planed for Version 1).

Who deserves credit for the Always-on-Sale logic?

The first artwork with this logic we use for ZeroAlpha was 'THIS ARTWORK IS ALWAYS ON SALE' designed, developed and implemented by Simon de la Rouviere in March 2019, who says about himself: "I'm a creator at heart. I helped to create the Ethereum ERC20 token standard and token bonding curves, technologies that's currently facilitating economies worth several billion dollars of value. I enjoy creating new forms of art and experimenting with ways to empower the creative industry."

How do payments work on ZeroAlpha?

ZeroAlpha operates on the xDai blockchain and accepts payments in the form of xDai, a cryptocurrency stable to the US dollar. In order to buy NFTs on ZeroAlpha, you must have xDai in your wallet, capable to interact with the xDai blockchain (see technical questions).

Does ZeroAlpha accept payment in any other cryptocurrencies?

Not at the moment. We're working on introducing payments in the form of other cryptocurrencies, such as PAN, HNY or xATS, in the near future.

Is ZeroAlpha holding any of my funds?

No. ZeroAlpha to completely non-custodial and all financial interactions you do are done directly from your wallet under your control.

Do cryptocurrency price fluctuations affect ZeroAlpha?

No. Because NFTs are traded in xDai they are stable in value expressed in US dollar. This might change in the future when more volatile cryptocurrencies might be used for some of the artwork, if the artist choses to do so.

What is an NFT?

NFTs, or 'Non-Fungible Tokens,' are one-of-a-kind tokens that represent a unique good or asset. They’ve been called 'crypto collectibles' because, much like trading cards, NFTs can be bought and sold by collectors. With scarcity and demand comes value—and when you add virality into the mix, NFTs representing digital art have the potential to open up dynamic marketplaces where artists can release unique artworks, and collectors can have fun buying them and provide patronage for a good cause.

Where can I look at NFTs I own?

The currently dominant way to look at all your owned NFTs is on the trading platforms themself, but more and more mobile wallets and browsers allow to display them as well. It is similar to Leonardo da Vinci's masterpiece "Mona Lisa", everyone can look at it when visiting the Louvre in Paris, some people have prints and pictures of it, but there is only one original, owned by the Government of France.

How does the initial sale work on ZeroAlpha?

The artist provides the artwork and defines the initial price for it. That is totally up to the artist and can be changed by the artist as long as it it not sold to a collector.

How does any consecutive re-sale work on ZeroAlpha?

As stated in the question about Always-on-Sale, the prospective collector has to define a re-sale price at the time of purchase. This is the price everyone can see and purchase the artwork at any given time.

What are the fees for buying and selling artwork on ZeroAlpha?

At the initial sale the artist and the ZeroAlpha platform split the money 50/50 and there is no additional fee to be payed to the platform by the collector. When the artwork is sold to a new collector, the current collector gets 90% from the sale price, 5% go as royalty to the artist and 5% will go to the ZeroAlpha platform to promote the mission.

How does the patronage work?

Every new owner has to deposit some xDai to pay for the 5% p.a. patronage - going to the selected non-profit organization - based on the proposed re-sale price. The amount for the deposit can be easily calculated by setting the date of the patronage duration. Any change to the duration of the patronage (extending, reducing, foreclosing) can be done by the current owner at any given time. If the artwork is re-sold the rest of the deposit will be automatically returned to the previous collector.

What happens if the deposit for the patronage runs out?

If the deposit for the patronage runs out and the current collector fails to top-up the deposit in time, the contract is foreclosing and the ownership of the artwork goes back to the artist. From there on it is handled like the initial sale and the artwork is automatically offered to new potential collectors at the original initial sale price, adjustable by the artist.

As a collector, how can I foreclose my ownership on the artwork?

If you are the owner of an artwork and want to give it back to the artist, you have to change the duration of your deposit for the patronage to the current date. This will trigger a foreclosing transaction, changing the ownership from you to the artist.
