Проект вроде относительно новый (или старый) 3 года вроде как запустили, но вот непонятно почему среди учредителей люди без фото и опознавательных знаков и только один с фото засветился, но фото прям с картинок про скам-ICO https://3dpass.org/community.html#About_usНу и за 3 года работы всего одна биржа вроде для обмена. Проект то точно нормальный? Не скам? Могу поделиться тем, что знаю: 1. Проект опубликован (WP) в январе прошлого года https://bitcointalk.org/index.php?topic=5382009.0, но они утверждают, что еще 1 год + работали над имплементацией алгоритма распознания, что в принципе понятно, так как алгоритм действительно ими был опубликован еще в 2020. (на этой странице ссылка есть на публикацию: https://3dpass.org/community.html#About_us2. В июне прошлого года была запущена тестовая сеть и приглашены майнеры на условиях последующего обмена тестовых монет на боевые после запуска mainnet. 3. В конце августа 2022 была запущена mainnet, все монеты были выплачены майнерам, участвовавшим в тестнет На этой странице можно найти пруф дистрибуции (скрипт): https://3dpass.org/testnet_rewards_runway.html4. В декабре 2022 залистились на биржу Xeggex Cейчас в сети около 500 публичных нод (сколько еще непубличных - не понятно): https://telemetry.3dpass.org/#/0x6c5894837ad89b6d92b114a2fb3eafa8fe3d26a54848e3447015442cd6ef4e66Кошельки и биржа Xeggex рабочие, лично пользовался неоднократно. Вот полкадотовский кошелек: https://polkadot.js.org/apps/?rpc=wss%3A%2F%2Frpc2.3dpass.org#/explorerВот их собственный: https://wallet.3dpass.org/Мобильный: https://3dpass.org/mobile_wallet.htmlКод полностью открытый (кошельки, нода, эксплорер, библиотека распознания pass3d): https://github.com/3Dpass/3DPПлюс еще китайцы сделали свою ноду и майнер: https://github.com/easy-3dp  Здесь доска с майнинг-лидерами: https://3dp.zhuaao.com/ кто-то тоже из комьюнити сделал ICO не проводилось |

The algorithm checks the blockchain to make sure there is no match. Of course this depends on how many fingers are set up to generate a decentralized identity. If 3DPass get's the algorithm and conditions right for generating a new decentralized identity then it would be 1 per person. Of course people can be very creative and I joked earlier that people will start scanning their toes  Nonetheless there would be a strong limitation on the amount of digital identity per real human being with the goal being 1. As I posted above there are ready to use tools that generates infinite amount of fake fingerprints. Even if they are not perfect to cheat this system ... if big money will come in ... people will find a way. I think this is harsh and I hope you can be open minded on the project.
Maybe indeed I am. 5 years in crypto made me very sceptical about new projects. I believe it is more secure and secured in a different way. More secure in the sense of multiple biometric data plus an additional object which is a crazy level of security. Plus most importantly it will be more user friendly than anything I've seen so far.
Scan two fingerprints plus your favourite sculpture for example. Good luck trying to figure this out for a hacker or forgetting this.
So its a super secured version of private key. Its a nice usecase too. But its not a digital identity because its not sybil attack resistant. And I would not compare it to having multiple passports. You go to jail for a long time if you get caught. Here you generate new fake fingerprint and scan random object and its ready. Let me give you one more example, which is a hardware wallet having implemented in of both Grid2d and fingerprint recognition algo. And those two would be used for HASH ID creation. The input data, now, can never be replaced, unless you have it as a physical item (a real finger or "plastic" finger). And all you need to prove is whether or not there is a real human being behind, right? I can see at least two possible ways to do that: 1. Meet him/her in person and verify the HASH ID with the hardware wallet 2. Trust a third party registrar (less trustworthy) Suppose, there should be some methods on top.. |

The only way to check if a given fingerprint belongs to someone real is to meet him in person and verify it by his finger.
So 3DPass is not a digital identity because 1 person can have infinite amount of digital identities. In my opinin, correct me if i'm wrong, it lose majority of use cases. KK, will do. pass3d recognition lib must contain both the fingerprint recognition algorithm and 3D object recognition ( Grid2d), which is actually there. That's how it works. It will prevent each digital identity from copying just as it does with 3D objects mined on 3Dpass blockchain (every object has a unique shape). Like 1 object = 1 asset. 1. As you can see on the picture posted by @3dpass, the HASH ID is created from several pieces of data when together being leveraged as a seed. But each of them represents an authentication factor you can never recover the HASH ID without having all of them: - a fingerprint is something that you are factor, which can identify the person easily (of course, in person); - a piece of stone is something that you have factor. - this combination might be expanded with some additional factors like a password ( something that you know), etc. So 3DPass is only a more secured version of private key. Or maybe not "more secured" but "secured in a different way". Because you can also hash your private key using "something you know" AKA password and part of your best book as "something you have" using simple softwere. 3DPass is nothing more than that. Am I wrong? Yes, you are. As it was mentioned above, the recognition algorithm is used in 3dpass instead of standard SHA2 hashing. I suggest that you read this article to compare and understand better how it protects objects from being copied: https://3dpass.medium.com/proof-of-scan-consensus-how-does-that-work-7a88b0fc8530that your bio has been already compromised (or even public), but the second factor is private and strong enough to protect your keys.
good point. But that doesn't this fact make bio useless in this system? It doesn't, cause that's exactly what makes HASH ID real personal digital identity. Bio data serves to identify a person, not to protect your key. Moreover, I'm not sure, your fear to disclose your bio makes that much sense nowdays. In most cases, it's already being public (iris scans on your selfie photos published on the Internet, fingerprints on your camera). Of course, if you want to stay private, you can live your life without making photos, hiding from public cameras with a hood etc... but it's not common. In my opinion, lots of people would prefer the possibility to use public digital identity for making p2p deals with real assets. Moreover, they would publish their iris scan with its HASH ID, so that 3DPass network can verify its authenticity. That's just my opinion. It doesn't make sense to keep in private something that you can't hide. |

Thanks, I see. Let me clarify my question a little bit. How does the private key identify me as a human being?
It doesn't have to do with me at all, right? So, it can't be treated as a personal identity, cause you'll never know who is the real owner of the private key. That's my point.
Let me give you an example. Imagine, you have 3 person coming over and claiming that each of them is the only owner of an IDENA account. All the three have the private key, which is correctly fit the account. How would you recognize the real one?
Just like with bitcoin wallet, etherum wallet etc. If you are irresponsible to the point that 3 people have access to your private key (which is suppose to be private) ... you are the one who is to blame for losing every asset that is on this wallet nor bitcoin or etherum network. Including digital identity.
In my opinion, that's correct, that they will lose their assets, once having their private keys compromised. But only assets, not the identity, cause it was never be there... (in the bitcoin wallet, etherum wallet etc.) They will never ever prove it were their assets stolen. 3DPass also doesn't prove that digital identity belongs to human being. Identity can be sold or sensitive bio-data can be stole from previous similar projects or malicious apps that needs fingerprint to unlock it or from compromised police office database or from passport issuing office. Just answer this question. How is it possible, in your opinion, that someone has a database of 1 million fingerprints?
I would disagree, and will try to explain my thoughts on it this way: 1. As you can see on the picture posted by @3dpass, the HASH ID is created from several pieces of data when together being leveraged as a seed. But each of them represents an authentication factor you can never recover the HASH ID without having all of them: - a fingerprint is something that you are factor, which can identify the person easily (of course, in person); - a piece of stone is something that you have factor. - this combination might be expanded with some additional factors like a password ( something that you know), etc. My first conclusion is that you can identify a human being, however, it's not enough to only have their fingerprint to recover the HASH ID and keys. It implies, that your bio has been already compromised (or even public), but the second factor is private and strong enough to protect your keys.  How 3DPass will deal with fake fingerprint data? I know its impossible to guess my fingerprint. The amount of possibilities are infinite. But creating a random fingerprints should be easy. How will 3DPass sort fake from real preventing 1 person from owning infinite amount of identities? For example this:  The only way to check if a given fingerprint belongs to someone real is to meet him in person and verify it by his finger. |

let's say I've got an IDENA digital identity (based on solving some CAPTCHAs, please correct me if I'm wrong).
Now, how can I prove it belongs to me (as a real human being)?
Private key is the thing that proves that you own this specyfic digital identity. Just like with every crypto wallet. But that's probably not what you wanted to ask, but how idena deals with the fact that one person has multiple nodes. Its the turing test i was talking about before. Its not a "some CAPTCHAs". Its 6 logic puzzles that you have to solve. This test is performed simultaneously for the entire network and short session last only 2 minutes. So there is no way to validate more than 1 identity. Well you can try with 2-3 but sooner or later you will run out of time and fail valition loosing stake and identity. Based on my experience with idena, 1 node is easy to have, 2 is hard, 3 is super hard and risky. Thanks, I see. Let me clarify my question a little bit. How does the private key identify me as a human being? It doesn't have to do with me at all, right? So, it can't be treated as a personal identity, cause you'll never know who is the real owner of the private key. That's my point. Let me give you an example.

I believe that a digital identity will be essential in the future as part of the evolution to Web3
There are a lot of challenges to getting this implemented in a way that is good for society and individuals.
You want to ideally meet the following criteria;
- Issued in a decentralized trustless manner
- Universally Recognized
- Secure
- Encrypted
- Recoverable
I have come up with a proposal on 3DPass in the below infographic on how this could be addressed.
This is by no means perfect but I truly believe this is better than anything I've seen anywhere so far.
The main issue which is still being discussed is what happens if someone steals your private keys.
Let me know what your thoughts? I'm especially interest in feedback on the Infographic below as well as other projects tackling this issue or even any comments you have in general on digital identity.
It's a great project for the future if it goes perfectly but I'm quite dubious about the service you will provide to customers, which as we all know we have different fingerprints until today, no one naturally have the same fingerprints. In the process your system will record the fingerprints that I did to get an identity in the web3 industrial revolution, in my understanding you will have my original biometric data in your system before being encrypted. until whenever possible you will have my fingerprints, in this case I want to question how your system cannot be broken into that maybe hackers will steal fingerprint data of billions of people who are in the original data storage system that you have. In the process, fingerprints will be found in the state big data as my identity in social life. The worst possibility is that hackers have my fingerprints from various sources and can match my identity elsewhere. I don't mean encrypted data but on the robustness of your system because of course your system keeps the original data to protect my identity. From my understanding of either 3dpass HASH ID and what @3DPass meant by his drawing above, the system doesn't collect any user's data except pub key and pub signature. HASH ID creation process is an offline operation being processed on user's machine without going outside. pass3d recognition opensource lib is only being involved in. Follow the White Paper https://3dpass.org/3DPass_white_paper.pdfIt's not enough to steal customer's biometric data from somewhere to recover its hash id. It's protected by several factors... I've sketched it up in a little different way. Hope it becomes better to understand: 1. Biometric data, HASH ID and Private key - are all in secret 2. Pub signature taken form HASH ID ensures it belongs to the Network address and, on the other hand, it provides "0 knowledge" of any sensitive data. 3. HASH ID is protected by multi-factor authentication (it's not enough to steal your fingerprint, you also have to get the second object to recover) |

If future Web3 Trustless Decentralized Identity would be based on Biometric Data ... the worst thing you can do is to share it with random project in ICO stage for few pennies. Why this data is needed for? To prove that you are the owner of identity? Thats why private key is for. To collect sensitive data and run away? Most likely. To avoid sybil attacks? Maybe but there are better alternatives that does not force you to expose to unlimited risks. For example IDENA and its Proof of Person network. It does not need any sensitive data. 1 node = 1 vote. Sybil resistance achieved by Turing test. let's say I've got an IDENA digital identity (based on solving some CAPTCHAs, please correct me if I'm wrong). Now, how can I prove it belongs to me (as a real human being)? Cee2 From my understanding, this HASH ID Identity doesn't provide any knowledge about my personal sensitive data, right? |
