A method including: at a data layer of a transport stack executing on transport circuitry: storing, in memory, identity information via memory operation; passing an information record of the identity information to a blockchain layer for provision to a distributed network for recordation within mutualized data on a distributed ledger; accessing the identity information in the memory; and after accessing the identity information, passing the identity information to an application layer of the transport stack; at the application layer of the transport stack: obtaining a request for a viewing-share of the identity information to substantiate an identity-dependent transaction; determining whether to grant the request; at a time that the request is granted: generating a grant record of the grant; passing the grant record to the blockchain layer; and causing provision of the identity information to fulfill the request; and at the blockchain layer of the transport stack, initiating collection of mutualized data by: causing the information record to be recorded on the distributed ledger; and causing the grant record to be recorded on the distributed ledger; wherein the mutualized data further includes an authenticity artifact establishing at least in part authenticity of the identity information; and the method further includes, at the application layer, serving the identity information and an authentication reference in response to the request, the authentication reference configured to point to the authenticity artifact within the mutualized data. at a data layer of a transport stack executing on transport circuitry: storing, in memory, identity information via memory operation; passing an information record of the identity information to a blockchain layer for provision to a distributed network for recordation within mutualized data on a distributed ledger; accessing the identity information in the memory; and after accessing the identity information, passing the identity information to an application layer of the transport stack; storing, in memory, identity information via memory operation; passing an information record of the identity information to a blockchain layer for provision to a distributed network for recordation within mutualized data on a distributed ledger; accessing the identity information in the memory; and after accessing the identity information, passing the identity information to an application layer of the transport stack; at the application layer of the transport stack: obtaining a request for a viewing-share of the identity information to substantiate an identity-dependent transaction; determining whether to grant the request; at a time that the request is granted: generating a grant record of the grant; passing the grant record to the blockchain layer; and causing provision of the identity information to fulfill the request; and obtaining a request for a viewing-share of the identity information to substantiate an identity-dependent transaction; determining whether to grant the request; at a time that the request is granted: generating a grant record of the grant; passing the grant record to the blockchain layer; and causing provision of the identity information to fulfill the request; and generating a grant record of the grant; passing the grant record to the blockchain layer; and causing provision of the identity information to fulfill the request; and at the blockchain layer of the transport stack, initiating collection of mutualized data by: causing the information record to be recorded on the distributed ledger; and causing the grant record to be recorded on the distributed ledger; causing the information record to be recorded on the distributed ledger; and causing the grant record to be recorded on the distributed ledger; wherein the mutualized data further includes an authenticity artifact establishing at least in part authenticity of the identity information; and the method further includes, at the application layer, serving the identity information and an authentication reference in response to the request, the authentication reference configured to point to the authenticity artifact within the mutualized data.
