These are some of the institutions that issue verifiable POK credentials

Frequently asked questions

POK has a built-in feature that allows credential recipients to add them to their LinkedIn profile in just a few clicks.

Once added, the credential appears in the “Licenses and Certifications” section of the profile, displaying details such as the issuing institution’s name, issuance date, and a verification link.

This increases the visibility of the achievement and strengthens the issuer’s brand, as anyone visiting the profile can verify the credential’s authenticity directly from LinkedIn.

For NFT credentials, the verification link can point to both the POK portal and the public blockchain record, offering dual assurance of validity.

For the purchase of NFT credentials, POK accepts:

  • Credit or debit card (Visa, Mastercard, Amex)
  • Bank transfer
  • Local payment methods depending on the country (e.g., Pix in Brazil, SPEI in Mexico, Electronic Payments in Argentina, PayPal internationally)


Invoicing adapts to the needs of each institution, with the option to issue international invoices in USD or other agreed currencies.

The implementation of POK is fast and frictionless.

In most cases, institutions can start issuing credentials the same day they create their account. The basic flow is:

  • Create the account and set up the organization’s profile (logo, legal details, templates)
  • Upload the recipient list or integrate with the LMS/CRM
  • Issue the first credential and enable its verification


If advanced integration via API or connection with internal systems is required, the time will depend on the technical complexity, but our team supports the process with guides, support, and onboarding sessions.

An NFT (Non-Fungible Token) is a unique and non-reproducible record on a blockchain that certifies the existence, authenticity, and ownership of a digital asset.

In the context of credentials, an NFT acts as a “fortified version” of your diploma or certificate:

  • It cannot be altered or duplicated
  • It contains metadata with all relevant information (name, date, issuer, criteria, evidence)
  • It can be verified independently, without relying on the issuing system


The great advantage of an NFT is that its validity does not depend on POK existing in the future: as long as the blockchain is active, the credential can still be verified.

Additionally, it can be stored in a personal wallet, shared on networks, or presented in selection and accreditation processes without needing confirmation from the issuer.
