A method for securely exchanging cryptographically signed records, comprising: under control of hardware processors: a record sender device: receiving a content request from a record receiver device; identifying the record receiver device; creating a sender individual record, wherein the sender individual record comprises a record content, a sender public key of the record sender device, a receiver public key of the record receiver device, and a sender signature of the sender individual record, wherein the sender signature is created using a sender private key of the record sender device, and wherein the sender public key and the sender private key form a sender public-key cryptographic pair; sending the sender individual record to the record receiver device; and receiving an indication of the record receiver device; and the record receiver device: receiving the sender individual record; verifying the sender individual record based at least in part on the sender public key; creating a receiver individual record (100m1), wherein the receiver individual record (100m1) comprises the sender individual record and a receiver signature of the receiver individual record (100m1), wherein the receiver signature is created based at least in part on a receiver private key of the record receiver device (100m1), and wherein the receiver public key and the receiver private key form a receiver public-key cryptographic pair; redeeming the receiver individual record (100m1) with a processing platform; and the processing platform: receiving a performance as instructed by the receiver individual record (100m1) to provide content requested via the record content request; generating common records from central records comprising the sender public key, the receiver public key, a user record status of the record sender device, and a user record status of the record receiver device; determining that the user record status of the record sender device prohibits the processing platform to perform as instructed by the receiver individual record (100m1); and adding the record sender device to a demerit list. receiving a content request from a record receiver device; identifying the record receiver device; creating a sender individual record, wherein the sender individual record comprises a record content, a sender public key of the record sender device, a receiver public key of the record receiver device, and a sender signature of the sender individual record, wherein the sender signature is created using a sender private key of the record sender device, and wherein the sender public key and the sender private key form a sender public-key cryptographic pair; sending the sender individual record to the record receiver device; and receiving an indication of the record receiver device; and the record receiver device: receiving the sender individual record; verifying the sender individual record based at least in part on the sender public key; receiving the sender individual record; verifying the sender individual record based at least in part on the sender public key; creating a receiver individual record (100m1), wherein the receiver individual record (100m1) comprises the sender individual record and a receiver signature of the receiver individual record (100m1), wherein the receiver signature is created based at least in part on a receiver private key of the record receiver device (100m1), and wherein the receiver public key and the receiver private key form a receiver public-key cryptographic pair; redeeming the receiver individual record (100m1) with a processing platform; and the processing platform: receiving a performance as instructed by the receiver individual record (100m1) to provide content requested via the record content request; generating common records from central records comprising the sender public key, the receiver public key, a user record status of the record sender device, and a user record status of the record receiver device; determining that the user record status of the record sender device prohibits the processing platform to perform as instructed by the receiver individual record (100m1); and adding the record sender device to a demerit list.
