These are tickets that contain various textual metadata fields related to a given artwork, such as:. There are other kinds of tickets as well, such as trade tickets for handling the trading of registered artworks between users.
For each piece of proposed new functionality, we design a ticket for that purpose, as well as a standardized protocol for validating and securing these tickets by the Masternodes and regular full nodes in the network. Aside from shielded transactions, Zcash is mostly similar to the Bitcoin codebase with various tweaks, most notably using Equihash as the Proof-of-Work algorithm rather than the SHA algorithm used in Bitcoin.
The company behind Zcash raised significant amounts of venture funding and was able to hire some of the brightest minds in cryptography, as well as retain several leading third-party security researchers to conduct detailed security audits.
That is why we decided that the Zcash codebase as it existed in mid was the best starting off point for the Pastel codebase. To handle the requirements of running a purpose-built, digital art cryptocurrency system while preserving maximal decentralization and ensuring that the system is scalable over the long term , we used the concept of a Masternode as pioneered by the Dash cryptocurrency project, which was introduced in January of Although not as commonly found in newer cryptocurrency projects, Masternodes represent an important extension of the core ideas of the Bitcoin system and provide a large amount of additional power and flexibility at the expense of some additional centralization and a moderate weakening of the proof-of-work security as compared to the classic Bitcoin system.
Essentially, instead of having every full network node in the Pastel system independently verify and handle all the functionality of the system as is done with Bitcoin full nodes , we have a class of special nodes called Masternodes which are dedicated, high-performance machines that can handle the demanding storage and computational requirements of verifying and serving digital art files.
Aside from a fast, internet-connected computer and the modest level of technical knowledge needed to set it up, the only requirement to create a Masternode on the Pastel network is that you must own 5 million PSL coins. The other benefit of Masternodes is that they create a healthy financial alignment between the owners of the machines that operate the network and the owners of PSL coins, which creates a virtuous cycle of incentives. If you have a big stake in the Pastel project i.
There are clearly attack vectors where a malicious Masternode can attempt to undermine the system, but we have designed various mechanisms to detect and prevent that from happening, as well as to track the reputation of nodes over time a decentralized way so that nodes which are observed manipulating or damaging the network can be voluntarily banned or ignored.
The basic organization of the Pastel code base is that it is a merger of Dash and Zcash; essentially, we ported over all the well-tested, proven Masternode logic from Dash into the Zcash codebase, which was extensively and professionally audited. All these services are bundled together for ease of deployment on Masternodes using Docker and Ansible scripts.
In addition, there is separate wallet software that is downloaded by users artists and collectors and installed on their computers. This wallet software exposes a user-friendly and intuitive interface that makes it easy for users to perform various tasks, including:. Artist, collectors, investors, and Masternodes all use the same PastelID system to establish their identities, which are used for all art-related transactions in the Pastel Network.
Browsing and searching through the network in a decentralized way using the Masternode network as the distributed servers all the available artworks. Trading artworks for PSL with other users of the system. We are looking into ways that we can possibly integrate some kind of stable-coin such as the Gemini dollar , where users can create agreement tickets with particular Masternodes where they agree to exchange a certain amount of the stable coin for PSL or for certain Pastel artworks.
Other pieces of software infrastructure that are already in place include a web-based blockchain explorer as well as a mining pool. Third parties are encouraged to build upon this initial infrastructure to add various optional or convenience services to the system. For example, if someone wants to make a centralized website with usernames and passwords as a frontend to Pastel say, to make Pastel more accessible to less technical users , they could simply a hook up to the same API endpoints as the local wallet software uses and thus provide access on behalf their own users.
This sort of system is clearly less decentralized than if everyone were to run the node software locally and sync up with the blockchain, and thus represents a clear compromise. But since this would be optional and not an intrinsic or required part of the system, if it stops working for whatever reason, the damage would be isolated to the users of that centralized service, and Pastel would continue working without issue.
Going further, a third-party exchange service could be set up by anyone that would allow for faster-paced, stock-market like price action, at the expense of being totally centralized. In addition, we hope to see the issuance of a wrapped PSL coin so that PSL can be traded on decentralized Ethereum exchanges such as Uniswap as an additional source of market liquidity.
However, we have no issue with including optional features that provide users with additional functionality. For example, to supplement the native Pastel storage layer with extra protection and redundancy, it would be nice if users could easily sync up their art image files along with the relevant blockchain tickets with popular cloud services such as Dropbox. So why would anyone want to go through the trouble of running a Masternode? The answer, of course, is that you get paid to run a Masternode: the network itself pays you, which is implemented as a share of the mining block reward which is automatically sent out to certain Masternodes in a provably fair, decentralized way.
That is, instead of the miners getting all the mined coins as is done in Bitcoin and Ethereum, some of these coins are given to the Masternodes as a group to compensate them for a running the network infrastructure, and b for their commitment to keeping their coins locked-up as collateral for the Masternode and thus not available for sale on the market. This is implemented by a fixed amount of the mining rewards set aside by the network for the Masternodes, which is effectively divided by the number of Masternodes.
In addition to this share of the mining block rewards, Masternodes in Pastel can also earn additional PSL as compensation for providing various services to users of the system. For example, Masternodes are automatically selected to act as agents on behalf of artists who want to register new Artworks on the Pastel Network in a clever way that makes it impossible for anyone to control which Masternodes are selected.
In return for handling this process, the selected Masternodes are paid a registration fee by the artist, which is dynamically determined based on the size of the art image file and the length of the corresponding metadata ticket as well as other factors such as the network hashrate to maintain affordability over time.
If the owner of a rare digital artwork on Pastel wants to sell that artwork to another collector or back to the artist, or to anyone else , they can submit an artwork sale ticket to the network that specifies the particular artwork they are trying to sell, how long the sale ticket will remain valid measured in terms of blocks rather than the date , and finally the price in PSL coins. Before the sale ticket can be accepted into the blockchain, all nodes on the network not just the Masternodes must verify the provenance of the artwork: that is, they trace the various tickets through the historical blockchain and check that there is a direct chain of tickets that begins with the initial art registration ticket and goes through all the previous valid trade tickets and finally ends with that particular copy of that artwork being owned by the seller.
For the sale to be finalized, another user must submit an artwork purchase ticket which specifies the artwork copy as well as the price in PSL coins. Assuming the buy price exceeds the sale price specified in the sale ticket and the PSL address of the buyer contains enough PSL to cover the full cost fo the trade and is otherwise valid, it is submitted to the blockchain. Finally, after a certain number of blocks have been written to the blockchain to confirm the purchase and sale tickets, an artwork trade ticket is submitted to the network by the buyer that summarizes the transaction and includes the required payment from the buyer to the seller.
Once the trade ticket has been accepted into the blockchain by the network, the buyer is able to request the art image file from the network so they can download it to their machine. For more details, see the section Artwork Trade Logic Validation. This approach of not trusting any network nodes, but instead always requiring multiple, randomly selected nodes to independently do computations and compare results so that a secure consensus can be reached, is pervasive across the Pastel project.
Masternodes are constantly checking up on each other to ensure that all Masternodes are keeping up with their obligations to perform in the network promptly and accurately. For example, Masternodes periodically challenge one another to prove that they are really storing the file chunks that they are supposed to be storing.
If their karma gets too low, they are penalized by the network by excluding them from participating in the Masternode block rewards for a certain number of blocks. The goal of this is to make the system such that, in order for an attacker to disrupt the network, they would need to control a high enough percentage of all Masternodes so that they could reliably count on all of the randomly selected Masternodes for each block being under their control.
Back in , we identified robust near-duplicate image detection as a critical requirement of any good blockchain art solution. We are the only decentralized project to even attempt to solve this difficult problem through purely algorithmic, objective means.
The reason we think this is so important is that we think rareness should not just be at the level of hashes and signatures. If the same image can be called different names by different artists and registered on the same system, it creates doubt and confusion. Once the expert signs off on the artwork, it is then registered on a blockchain, and can be traded with others. In other crypto art projects, the issue is side-stepped entirely by ignoring the image itself and putting all of the emphasis on the signatures.
Not only does this signature-only approach increase the chance of users being misled and confused, but it also means that artists can undermine the rareness of their artwork themselves. If that artwork later becomes famous and coveted, the price in PSL for those 10 copies could skyrocket. Even if collectors could see that it was part of a later series since it would be registered in a later block in the blockchain , it would still depress the value of the original series.
Thus, by preventing near-duplicates or at least identifying near-duplicates as such , Pastel protects art collectors from greedy artists in addition to general counterfeits submitted by other malicious users. Other crypto art projects make a big point of integrating some means of filing and mediating copyright disputes.
If the person gets there faster than the true owner of the legal copyright in this case, Disney , what should happen? Tradition tells us that Disney should be able to request and force the removal of the copyrighted content. We believe that there is no way to bridge the divide between the real world and the blockchain world without dramatically undermining the decentralization and security of the system. Once you get lawyers and judges involved, and judgements are given, some person or entity has to be in a position to execute those judgements, and thus they are a single point of control.
This also creates a sense of excitement and urgency in the project, where there is a reason to get moving on the platform. In the ticket, the user can include a textual narrative making their case. The petition ticket could then be reviewed by Masternode operators, who would be under no obligation to review or vote on anything.
But if enough Masternodes could be convinced to review the case and vote in favor of the petitioner, then a new ticket can be written to the blockchain essentially canceling the original registration and transferring it to the petitioner. The reason the problem is so difficult is because most ways of characterizing an image are brittle. The typical way things like this are done in crypto projects is to take the SHA hash of the file and use that as the ID or fingerprint of the image.
The problem with doing it this way is that someone could take the image and edit it in photoshop and change just the lower left pixel very slightly and then save the file, and this would cause the SHA hash to completely change, even though to the human eye the image is identical. For example, we should be able to spot it if someone takes an image that has already been registered on Pastel and then tries to re-submit the image after doing any of the following modifications:.
When that happens, the Masternodes selected to handle that artwork registration will refuse to sign the registration ticket, and the artist who submitted the registration request will be notified that their artwork is too similar to an existing registered image, losing the PSL deposit that the artist sent to the Masternodes to start the process. If every registration attempt costs a real amount of money, people will use them more carefully. Our approach to near-duplicate image detection in Pastel is basically to find a way to transform each image into a fixed list of around 8, numbers.
This vector of numbers is the image fingerprint, and it allows us to compare two images by comparing their fingerprints, which take up a tiny fraction of the space of the actual images. We can think of each fingerprint as representing a point in space, but where space is 8,dimensional instead of 3-dimensional. Then we can find suspiciously similar images by looking at the correlations between a given image fingerprint vector and the database of all the previously registered image fingerprint vectors.
The hard part of course is generating these 8, numbers intelligently. Luckily, we can rely on the combined efforts of Google, Open-AI, and numerous other researchers in the machine learning community.
