In the end I would say that all of your other questions can be reduced to this one, by adding weight to claims, which makes the quantity of claims and indentities irellevant.
We are not focused on the art market, but open to any kind of information. But for the example of the art ownership verification:
- Person A (true owner) claims that they own the Mona Lisa with a weight of 10 tokens
- Person B (non-owner) claims that they own the Mona Lisa with a weight of 10 tokens
- An additional actor X who knows about the ownership can add additional weight to the claim of Person A. If the consensus in the end decides (based on the weights) that Person A is the true owner, actor X will be rewarded. There are some specifics about how we construct the reward function that I can't talk about yet, but the core of it is that all participants in the network are incentivized to only submit true information, and also incentivized to combat any wrong information they see by providing conflicting true information.
If you are interested in the topic and would like to discuss more deeply feel free to reach out to me via the email on the website (I'm Max).
It does indeed seem exactly that way. You said upthread:
>An additional actor X who knows about the ownership can add additional weight to the claim of Person A.
But how do you verify that X is someone "knows about the ownership"? What if X was someone A or B paid or incentivized to vouch for them so the consensus would be swayed? How do prevent bad actors from gaming the system in this way? If the asset in dispute is valuable enough it would certainly be worth it to a bad actor to pay a little to cheat and have the consensus fall on their side.
If B were to pay X a bribe of amount N, so X enforces the statement with amount N, B could also directly enforce the statement with amount N, which would lead to exactly the same result. If X would receive less than N, to add a weight of N, they would be gifting some money to B, and vice versa. So between rational untrusted parties, a simple bribe would not make sense. There are some rationality assumptions relating to 51% attacks similar to PoS oriented systems that have to be met, but there are some mechanisms in place that should reduce the practical requirement regarding rationality among participating parties significantly.
> If the asset in dispute is valuable enough it would certainly be worth it to a bad actor to pay a little to cheat and have the consensus fall on their side.
Good question, but I'm afraid that's one of the questions I can't answer right now without leaking too much information.
Okay, better question: how do you deal with the (pathologic, and therefore approximately guarranteed to come up) situation where A's life savings are ten dollars and a horse, B has 100 million dollars, and B claims (with amount ≥ 11$) that B owns A's horse.
As I said in my previous comment, there are some rationality requirements regarding some of the token amount.
You're assuming the bribe comes in your made up currency. B could bribe X with real money or out of band coerce/intimidate X with threats and violence.
So a connected market with goods that can be bridged similar to the stock market.
> or out of band coerce/intimidate X with threats and violence
I'm not pushing for a world without governments and law enforcement.
What will you do in polemic cases? For example, some people think that La Gioconda is own by the Italian people and should be returned to Italy (because Leonardo was Italian). What would you do if there is a huge campaign to claim that it is owned by some Italian museum? What about the Tutankhamen mummy? Alaska?
Not at all, and I don't know where you are getting that idea from. The system, as it is designed right now has no requirement for a single centralized or trusted party. It also has no requirement for any trust between the participants (which most systems in the same realm do).
> What will you do in polemic cases?
That's a good question, and one of the things we want to explore during iterations of the testnet. Without going into more specifics I would say that there is a part of the incentive mechanism that rewards a more clear-cut consensus (a 50/50 split on a boolean statement is the least favourable situation for participants on both sides). This unfavourable situation should then in turn fuel the contribution of more information so people can make a more informed rational decision which should then lead to a more clear consensus. There are also some higher level market mechanisms that we anticipate to develop which could be used to both stabilize and destabilize the consensus about a certain statement, like a off-chain PR campaign as you mentioned. We'll have to see how each of those can potentially impact a consensus and if that is something that needs a countermeasure in the core protocol.
I know you said your system isn't tracking this specifically, but the general principle remains true in any problem domain. The integrity of a common-consensus system depends entirely on how little trolls care about disrupting it.
That is actually the key point why a blockchain (or ledger that allows for money-like transaction) is an important part for us. By binding what you say to a monetary reward people that act irrationaly and do it for the lulz will lose their money and ultimately have to leave the system by running out of funds.
Simmilarly, trolls could dimish the value of a PoW blockchain by creating and exploiting 51% attacks, but that hasn't happened with Bitcoin, since that is far too expensive to do it just for fun. Monetarily motivated attacks are of course a different discussion.
The art example is a great demonstration of the mismatch. There is essentially zero value in the truth, so it was worth a bit of the author's time for the lulz.
With cryptocurrency, the cost to subvert the truth is pretty high, so the value of doing so, although high, doesn't exceed the cost. With anything for which the value isn't inherent, like a cryptocurrency, it's hard to see that working out.
I mean, if I'm using a hypothetical art-ownership blockchain system, and I see that someone has spent $5 to claim authorship of Mona Lisa, do I care enough to spend $6 to say no, it's Leonardo? Do I care enough to spend even $1, along with five other people? What if 200 4chan trolls have each pitched in a dollar to say Hitler painted it? Eventually, maybe, enough people kick in a combined $201 to say no, seriously, it was Leonardo. But then what? Am I expected to continue paying a regular fee to maintain the truth? Why would I even care that much?
Wikipedia is a great example of something working really well, but many of the reasons it works so well are contrary to what you've described. It is in fact often people with far more time than money that ensure the truth generally remains on wikipedia, and they use non-blockchain-like tools, including the exertion of authority and locking of article pages, to do it.
I'm not trying to crap on your super-sekret whitepaper at all! I'm mostly thinking this through as I type, and responding to the poor design, heck, the poor goal of the described art-authorship application. You might have solved all of this in a way that doesn't depend on trolls being poor or getting bored easily. I hope so.
I would argue that most markets in existence are fundamentally based on that holding true. And somehow the world, for some reason inexplicable to me hasn't collapsed yet.
> Wikipedia is a great example of something working really well
In the general case, yeah I agree. However, there have also been cases where authority on Wikipedia has been blatantly misused to overrepresent personal views of privileged contributors and censor contradicting contributions. I'm not saying that permissioned information/knowledge gathering platforms like Wikipedia have no right to exist - as with any centralized system they probably have efficiency gains - but I think there are some properties of it that can be improved upon.
If your solution is counting on "some reason inexplicable" that took me literally two sentences to easily and accurately explain, I'd worry.
If you think trolling hasn't caused collapses, well, I note that your site has four pictures of people who are unlikely to experience what I'm talking about.
Wikipedia definitely has issues, but most of those issues involve exactly the sorts of things we're talking about here: trust, and who has it. Most of their issues would be solved with more centralized control, not less, and still the issue of who to trust with that control remains.
Yes, since traditionally the cost of trolling is ~the cost of the time of the troll. Do you think the internet would look the same if there would be enforceable fines on slurs in Tweets or Youtube comments? More relatedly, have trolls managed to destroy Bitcoin and Ethereum, which are based exactly on those anti-trolling mechanics of rational players being in place?
> the core of it is that all participants in the network are incentivized to only submit true information
How is this done? What is the incentive?
The combined reputation from many of these services could act as a badge of trustworthiness on the blockchain. You just need a system like Keybase to cryptographically associate accounts to a public key.
I have been shocked to see so few crypto solutions integrate with Keybase as a trustworthy identity network. I wonder why people aren't doing this?
How do you combat "spam", were some users send thousands of fake registrations of well known art works?
How do you combat sockpuppet that send wrong opposing information to steal the art work of the original creator?
How do you combat sockpuppets that send wrong information to support fake claims?
If some piece of art has two claims, who decides which one is the correct?
