Request for feedback on an open COA standard

[ScarceCity]

Hi, I'm developing a Bitcoin-based open standard for Certificates of Authenticity (COA) for physical art.

It's similar to Verisart in that it uses Opentimestamps but the goal is to get closer to true authenticity with a trustless standard that anyone can use to create or verify COAs.

Here's a video demo on the current version: youtu.be/9mZyG7-KVs0

Any criticism and suggestions are greatly appreciated. I have a couple artists ready to use them so I want to make sure they're battle tested.

Thank you

Sure. I am on a break now. I will watch the video and give you the criticism based on what I feel. Thank you for asking. Best regards, Rainbowsky.

The training video is nice on how to create COA for blockchain asset but I like to know if this is a  blockchain COA  meaning will this COA will be  on the blockchain or this is a Physical COA for blockchain asset?

Overall it is a good work. Thanks.

Thanks for taking a look!

The COA is hashed and added to the Bitcoin blockchain through opentimestamps.org.

It is not meant for blockchain assets (tokens) but instead physical items such as paintings/sculptures.

The COA is linked (IPFS) in an NFC tag which is attached to the physical work.

Please let me know if you have any other questions or comments!

Thank you for answering. Are you using any special hot foil, security paper, hologram, embroided seal, hidden image can only be seen by laser, text threads, convert information only revealed by UV light, bar code for your COA?

What happens when chiefmonkey decides to use a different creator address? or loses access to the ability to sign messages to that address for previous pieces issued?

What if a susbsequent owner loses their private key in order to transfer that COA to a new owner? (This is true for anything on Rarible as well, obviously). Now they own the physical art, but cannot transfer the digital COA...

The Timestamps are great. Kind of reminds me of what factom did. Being able to upload a pdf into a hash.

No, just the NFC tag which links to the IPFS hash of the COA.

In my mind, the opentimestamps hash serves the same purpose as the authentication mechanisms you've listed.

Please let me know if you see it differently.

Thanks!

Our COA does require the artist to generate and secure the private key of their creator address. We could technically custody it for them (as Verisart does) but we are a Bitcoin company and strongly believe in self-custody.

The owner providing the transaction ID alone may be a strong enough assurance for prospective buyers. They'll have record of it in both the wallet used to make the transaction and the purchase confirmation email. Signing a message with the owner address private key is the ultimate assurance which can be done with most modern wallets. So really, they just need to maintain access to the wallet.

But yes, in both cases maintaining the COA requires responsibility. Like Bitcoin
