yes, especially for the API because there's no cost relative to hosting the docs

whcich blockchain? Is it a blockchain accessible to anyone to verify?

Hello Peter! This article presents the solution but to explain a little bit more, the general configuration for eSignature in Woleet Sign is the platform generating keys for each signer (generated randomly in each request) and then send private links by email and OTP SMS if a phone number is provided. So in the end Woleet timestamps a proof that the person controlling a specific email and a specific phone number had a specific document in his possession and agreed to sign. It's also possible to use our signature system with your own keys associated with people with verified identities (KYC), to comply with "advanced" eSignature regulation in Europe.

we do not reinvent the wheel here the proof generated is downloadable in the chainpoint format (https://w3id.org/chainpoint/v2) and we also support Opentimstamps format. The verification tool allows you to download the chainpoint V2 format only though

We use layer 2 technology, the main idea of woleet is to stamp many hashes (possibly millions of hashes in one bitcoin transaction) our service is running for years and we produce thousands of proofs daily.

I get it, and no, nothing proves you didn't modify it. Maybe a solution is to create some king of "witness community" stamping the same page at the same time. It will have diferent hashes each time and the evidence could be stronger in the end

this tool does not guarantee that you've not modified the export before you stamp it. The main protection is the timestamp and the fact that the hash is calculated by the extension itself. This proof just guarantee that this particular file existed at this date. I personnally believe that even if it's not a siver bullet, the certain date is the main protection it provides. If you want to make some fraud with a bitcoin timestamp, you need a proper timing and preparation. In conclusion it just makes things harder

hi, I'm woleet's ceo. I can give you all the details you want. To explain it simply, for each signleFile export we "anchor" the hash in Bitcoin. It means each hash is link to one particular bitcoin transaction. Feel free to ask any question I'll be happy to answer
