Systems and methods for selectively revealing verifiable private information on a blockchain

A non-transitory computer-readable medium having software instructions stored thereon, wherein the software instructions, upon execution, are configured to cause at least one processor to perform a method comprising:

• transmitting, by a computing device to a keyless account service comprising a third-party authentication server, an authentication request, the authentication request comprises at least one of a name, an email address, a phone number, an application identifier, a device identifier associated with the computing device, a user identifier, a social media profile, or any combination thereof;
• receiving, from the keyless account service, in response to a positive authentication of the authentication request, an authentication token comprising a keyless account service signature and to-be-revealed information attested to by the keyless account service;
• wherein the keyless account service signature is associated with a keyless account service public key of the keyless account service and is computed over at least the following:
• a first public key associated with a managing application of a user, and
• the to-be-revealed information attested to by the keyless account service;
• generating a request to perform a particular activity and an activity signature,
• wherein the activity signature is associated with the first public key and is computed over at least the request to perform the particular activity;
• submitting, to a blockchain network, via the managing application, the request to perform the particular activity, the activity signature, and at least one proof of knowledge of the keyless account service signature being a valid keyless account service signature computed over at least the to-be-revealed information:
• wherein the blockchain network is configured to:
• validate the request to perform the particular activity, based at least in part on a verification, using the first public key, of the activity signature;
• obtain and reveal the to-be-revealed information based at least in part on a verification, using the keyless account service public key, of the keyless account service signature to generate a revealed information;
• validate the keyless account service signature by verifying the at least one proof of knowledge of the valid keyless account service signature, wherein the valid keyless account service signature validates the revealed information as attested to by the keyless account service;
• and
• wherein, upon successful validation of the activity signature, and the keyless account service signature, the blockchain network is further configured to:
• permit at least one operation based at least in part on the request to perform the particular activity.

A system comprising:

• at least one processor in communication with at least one non-transitory computer readable medium having software instructions stored thereon, wherein the at least one processor, upon execution of the software instructions, is configured to perform a method comprising:
• transmitting, to a keyless account service comprising a third-party authentication server, an authentication request, the authentication request comprises at least one of a name, an email address, a phone number, an application identifier, a device identifier associated with the computing device, a user identifier, a social media profile, or any combination thereof;
• receiving, from the keyless account service, in response to a positive authentication of the authentication request, an authentication token comprising a keyless account service signature and to-be-revealed information attested to by the keyless account service;
• wherein the keyless account service signature is associated with a keyless account service public key of the keyless account service and is computed over at least the following:
• a first public key associated with a managing application of a user and
• the to-be-revealed information attested to by the keyless account service;
• generating a request to perform a particular activity and an activity signature, wherein the activity signature is associated with the first public key and is computed over at least the request to perform the particular activity;
• submitting, to a blockchain network, via the managing application, the request to perform the particular activity, the activity signature, and at least one proof of knowledge of the keyless account service signature being a valid keyless account service signature computed over at least the to-be-revealed information;
• wherein the blockchain network is configured to:
• validate the request to perform the particular activity, based at least in part on a verification, using the first public key, of the activity signature;
• obtain and reveal the to-be-revealed information based at least in part on a verification, using the keyless account service public key, of the keyless account service signature to generate a revealed information;
• validate the keyless account service signature by verifying the at least one proof of knowledge of the valid keyless account service signature, wherein the valid keyless account service signature validates the revealed information as attested to by the keyless account service;
• and
• wherein, upon successful validation of the activity signature, and the keyless account service signature, the blockchain network is further configured to:
• permit at least one operation based at least in part on the request to perform the particular activity.
