The invention presents a solution in which blockchain Transactions are created to implement the functionality of a logic gate. The invention may be implemented on the Bitcoin platform or an alternative blockchain platform. The transaction includes a locking script which comprises instructions selected so as to implement the functionality of a logic gate, such as the XOR gate. When the script is executed (because a second transaction is attempting to spend the output associated with the locking script) the inputs will be processed by the conditional instructions to provide an output of TRUE or FALSE. The inputs are pre-processed by one or more computing agents so that they are evaluated to TRUE or FASLE prior to being used as inputs to the script. The second transaction is transmitted to the blockchain network for validation and, if determined to be valid, it will be written to the blockchain. Validation of the second transaction can be interpreted as a TRUE output. Thus, the locking script of the first transaction provides the functionality of the desired logic gate. The invention provides numerous advantages and can be used in a wide variety of applications, such as for the implementation of control systems and unit.

Systems and methods to create a customized watch face and retrieve the watch face to be displayed are disclosed. Exemplary implementations may effectuate presentation of a selection interface; receive a mint request to mint the watch face in accordance with a watch face design; effectuate a transfer of consideration from a user wallet to an administrative wallet; mint the watch face; transfer a non-fungible token to the user wallet; receive a display request to display the watch face on a watch screen; determine whether the user wallet holds a non-fungible token associated with the watch face; responsive to the user wallet holding the non-fungible token, facilitate display of the watch face on the watch screen; responsive to the user wallet not holding the non-fungible token, take no action to facilitate display of the watch face on the watch screen; and/or perform other operations.

Supply chain factoring utilizing shared state information stored in a distributed ledger includes the selection of an electronic supply chain document associated with an order for goods by a purchaser of the goods and the minting of a cryptographic token on behalf of a seller of the goods. the token encapsulating a purchase price for the order and associated order terms. A location is reserved in the ledger into which the token is uploaded. Subsequently, factoring terms are published at the reserved location by a factoring agency supporting the factorization of the purchase price. The seller then validates an ascension to the factoring terms in the reserved location. Finally, the reserved location is annotated to indicate satisfaction of the factoring terms upon the purchase price being paid to the factoring agency and a fraction of the purchase price being paid by the factoring agency to the seller of goods.

A digital currency system that may make use of a distributed network in validating coin ownership as part of processing of transactions of coins of the currency. Compute devices may include both wallet modules and teller modules, with the wallet modules used for user access to digital currency related functions and the teller modules used for processing transactions of the many users. The system may provide automatic denomination coin unit change. The digital currency may be transformed into a physical representation. The digital currency may be virtual currency or cryptocurrency.

A system and its methods are described for implementing meta-transactional interactions across one or more decentralized computing networks (“blockchains”) with a managed (“custodial”) wallet, satisfying an important need of lowering the barrier of entry for interacting with smart contracts across multiple blockchain networks. First, the method of encoding and storing a transactional request created by a user's managed account, representing an intention to broadcast the invocation of a specific function of a specific smart contract on one or more peer nodes of a specific blockchain. Then, calculating a cost for processing the encoded transaction within the specific blockchain via analysis including the value and type of cryptocurrency, complexity of transaction, historical trend of transaction fees, and analyses to eliminate the chance of loss due to insufficient transaction fees. Next, obtaining a payment from the user for the transfer of the amount to successfully process their queued transaction. Then, confirming the payment was received in its correct and sufficient form resulting in a transfer of cryptocurrency from a reserve to the user's managed account. Subsequently, determining the transfer is completed and a sufficient balance exists for the execution of the queued transaction. Finally, dequeuing and executing the stored transaction on a specific blockchain by the system on behalf of the managed account, where transaction fees are paid by the managed account and unspent fees are accrued in the balances of the managed wallet.

A method for authentication of coupons using a blockchain includes: storing transaction data for a payment transaction, wherein the transaction data includes at least a transaction amount; receiving an identification value; receiving a block included in a blockchain, wherein the block includes at least a block header and a plurality of transaction values, each transaction value including at least a coupon identifier and coupon data; executing a query on the received block to identify a specific transaction value of the plurality of transaction values where the included coupon identifier corresponds to the received identification value; and executing a query on the memory to update at least the transaction amount included in the stored transaction data based on the coupon data included in the identified specific transaction value.

Example methods, apparatuses, and systems are presented that allows a consumer to conduct a purchase backed by a volatile currency that is not recognized by a merchant as a valid form of payment, such as a cryptocurrency. A third-party payment system is configured to issue a secure, reliable token to replace a reserved amount of volatile currency that represents a reliable amount of currency that is recognized by the merchant as a valid form of payment. The third-party payment platform may issue the reliable amount of currency in the reliable token based on one or more risk factors associated with the volatile currency. After purchase, the third-party payment platform may perform a consumer settlement process at a later time, including performing a cryptocurrency blockchain verification process that typically takes at least several minutes and would be impractical to perform at the point of sale.

A method for a protocol in digital asset trading includes step as follow. Trading information is exchanged between the first and the second nodes, in which a first digital currency belonging to the first node and a second digital currency belonging to the second node are expected to be exchanged, and prices of the first and second digital currencies are time-dependent. An atomic swap script and a smart contract are generated. A compensation fee to be paid to the second node by the first node is computed. A redeeming or refunding event is performed in response to the atomic swap script and the smart contract with paying the compensation fee to the second node, in which the compensation fee is dependent on the prices of the first and second digital currencies such that is time-dependent.

Systems and methods for tokenization, management, trading, settlement, and retirement of renewable energy attributes are disclosed. In one embodiment, in an information processing apparatus comprising at least one computer processor, a method for tokenization, management, trading, settlement, and retirement of renewable energy attributes may include: (1) identifying renewable energy generation data associated with a seller to tokenize; (2) generating at least one renewable energy token for the identified renewable energy generation data; (3) writing the renewable energy token to a first distributed ledger; (4) adding the renewable energy token to a digital wallet for the seller; (5) exchanging the renewable energy token for a cash token owned by a buyer by associating the renewable energy token with the buyer and associating the cash token with the seller on the first distributed ledger; and (6) retiring the renewable energy token.

This disclosure describes aspects of an efficient blockchain API communication mechanism that reduces the energy usage and data usage. In some examples, a publish-subscribe mechanism is used for completed transaction receipts for blockchain transactions of a blockchain. The publish-subscribe mechanism uses an open source remote procedure call protocol or hypertext transfer protocol (HTTP). Components of a distributed blockchain application use a single transport or communications protocol for both synchronous and asynchronous communications.
