Q: We'd like to use Block.co. What are our next steps?

Contact us today to discuss your requirements and provide you with a bespoke package.

Q: How is the issuer identity verified?

The identity of the issuer is important and needs to be verified. We deal with this by including several identity verification mechanisms. Right now, we support two such mechanisms. One is domain verification where the identity is proved by proving ownership of a specific Domain Name Server (DNS). Additionally, we provide a Block.co verification service where we take care of manually verifying the issuers. More verification methods will follow, like Keybase, Github or social media accounts.

Q: Is there any possibility you would share, sell, distribute, document holders information?

No. Our agreements clearly state that we’re not able to share your data with any third party that’s not bound by our data privacy agreement and that isn’t named on our data privacy agreement.

Q: Does the data contained on Block.co belong to users or Block.co?

You’re always able to remove data you’ve provided to Block.co from our platform.

Q: Can I get my data off of the system if I decide to stop using Block.co?

Yes, this may be easily done. You can export your issuance data as a spreadsheet, and your certificates as PDFs at any time, free of charge. You may also submit a request at any time to enquiries@block.co if you’d like Block.co to remove data that you’ve provided to our platform.

Q: If we decide to stop using Block.co, do our vPDFs still work?

Your vPDF will be working fine, and vPDF recipients will be able to use them even if you stop using Block.co or even in the case that Block.co does not exist as an entity. You can visit or deploy the open source validating tool at any point and continue using the self-verifiable and self-contained digital documents at your will.

Q: How does the validation work?

VALIDATION OF DOCUMENTS Go to an online validator found on issuer’s and other websites. Upload the VPDF file. Get an immediate response as to its validity including detailed information.

Q: How does the revocation or expiry work?

REVOCATION OF DOCUMENTS An additional transaction is created on the Blockchain that invalidates previous records without erasing audit trail. You may also set a date for an automatic expiry in the future.

Q: What are the technical details that can be seen when you validate a vPDF?

During validation, a user validating a vPDF document will see the blockchain address that uniquely identifies the entity that anchored (or issued) PDFs. There also is a technical section that displays which blockchain and in exactly which transaction is the PDF’s hash stored. Finally, a timestamp of exactly when the document was anchored on the blockchain is displayed.

Q: In which ways can our clients interact and use our services?

We provide a SaaS (or BaaS) platform that greatly simplifies the process of creating vPDFs. We also provide an API that allows programmatic access to the same functionality allowing complex integrations with other platforms.
