Abstract: A system and method for bootstrapping a cryptographic ledger based on stake in a fiat currency. Stake can be verified using proof of cash systems involving anti-spoofing, anti-counterfeiting, and remote verification and transaction functionality. Stake can further or otherwise be verified using proof of balance systems involving verification of one or more balances using a service of a financial institution or data provider. These systems, together or separately, can be utilized to implement a cryptographic currency and application platform enabling financial transaction and general computing capabilities, in accordance with various embodiments of the invention.

Abstract: An embedded picture can be embedded with secret embedded payloads. A method is disclosed for performing trusted binding between a first participant and a second participant based on RSA cryptosystem using the embedded picture having a first area assigned to the first participant for a first secret embedded payload, and a second area assigned to the second participant for a second secret embedded payload. Multiple payloads may be embedded in the embedded picture by multiple participants. Each payload can only be encrypted and decrypted by its corresponding participant. Multiple participants may form a trusted network, in the network each participant can be recognized and validated digitally. Accordingly, various activities such as transaction of digital credit card, verification of digital identification (ID) card, transaction of digital currency note may be performed using the trusted network.

The network device is configured to receive, over an electronic network, public keys of two or more second public-private key pairs. The network device is configured to generate a digital currency address using the public keys of the two or more second public-private key pairs and a public key of the first public-private key pair.

Abstract: Implementations of the present specification disclose blockchain data processing methods, apparatuses, devices, and systems, including a computer-implemented method for blockchain data processing. Blockchain transaction data of a plurality of transaction participants is received. Each of the plurality of transaction participants provides a respective certificate indicating a respective legal membership in a blockchain. The respective legal membership enables processing of the blockchain transaction data. A mutual identity querying is performed to confirm whether each of the plurality of transaction participants has the respective legal membership in the blockchain. Supervision keys of a supervision node in the blockchain are determined, where the supervision node corresponds to a supervisor, and where the supervision keys are dynamically updated based on a predetermined rule. The blockchain transaction data is encrypted by using the supervision keys. The blockchain transaction data is stored.

Abstract: An automated method is provided for initiating a transaction function in a transaction processing device. The method comprises establishing near field communication between the transaction processing device and an NFC transmitting device having an associated tag identifier and receiving NFC information including the tag identifier. The transaction processing device transmits the NFC information to a merchant processor and receives from the merchant processor a tag rule communication including an instruction to carry out a transaction function associated with the tag identifier or a request to associate a new transaction function with the tag identifier. Responsive to receiving an instruction to carry out a transaction function associated with the tag identifier, the transaction processing device executes the transaction function.

After establishing the secure communication session, the service provider determines that a second area of the online account is in a locked state. The service provider determines that the user has reduced a balance associated with the public cryptocurrency address during the secure communication session, and in response to determining that the balance associated with the public cryptocurrency address has been reduced during the secure communication session, unlocks the second area of the online account.

Abstract: One embodiment of the present disclosure provides a system and associated processes for sharing cardholder data (CHD) between a merchant that utilizes tokenization and a second merchant that may or may not utilize tokenization. In one embodiment, the merchant, or an employee of the merchant, can use the system and associated processes to reacquire CHD from a tokenization provider system.

Abstract: Embodiments enable a block chain distributed network arrangement system for facilitating a tiered dedicated block chain configuration to provide differing combinations of functions and levels of security. The system may identify factors within received information that indicate which dedicated block chain network should be used to record the received information. The dedicated block chains may be tiered based on the importance of the received information or a customer service level of a party associated with the received information. The system allows for recording of the received information in a distinct, dedicated block chain network that is appropriately configured for the functionality and/or security requirements of the received information.
