A method for executing a transaction between a first party and a second party in a system including an operation server, connected with a transaction processor. A first party device and second party device are connected with the operation server. The method includes providing a unique transaction identifier (UTID) associated with the transaction; transmitting first payload information from the first party device to the second party device; notifying the operation server about the transaction; generating a second payload information by the second party device and sending the second payload information from the second party device to the operation server; and authorizing the transaction in the transaction processor by the operation server based on the second payload information and receiving a result of the authorization by the operation server.

A method for operating a mining pool includes running, by a mining pool operator, a blockchain node and at least one enclave. The blockchain node is connected to the enclave as well as to a blockchain P2P network and to a publicly available site. The method further includes checking, by the blockchain node, validity of incoming blocks and transactions received from the blockchain P2P network, and forwarding information on the received blocks and transactions to the at least one enclave. The method further includes creating, by the at least one enclave, a state transparency log and inserting the block and transaction information received from the blockchain node into the state transparency log, and signing, by the at least one enclave, the state transparency log and publishing the state transparency log at the publicly available site.

An automated payment delivery system is provided that combines electronic investigative data methods with fintech payment systems to deliver payments to payees. The system can be configured to receive payee account information, optionally enrich the payee account information through data discovered in public and private databases, automatically generate communications to each payee, verify the identity of the payee, send communications to the payee through a partner system, and initiate electronic payment to the payee.

A method for certificate transaction validation of a blockchain-based resource public key infrastructure aims to avoid security threats caused by conflicts or illegal transactions during transactions and improve security. A technical solution is as follows: constructing a resource public key infrastructure RPKIB system composed of a resource issuer, a resource transaction application client, a resource receiver, a blockchain network and a validation node; designing operations of a resource certificate and route origin authorization ROA as transactions, submitting operations of various resource transactions initiated by a resource issuer as transactions to the blockchain network, running, by the validation node, a smart contract to verify the transactions, and distinguishing whether the operations are malicious behaviors or normal operations of an authority.

An integrated supply platform system may include a blockchain database maintained by a blockchain network having a plurality of nodes. A plurality of tokens may be maintained in the blockchain database. The system may include smart contracts describing a deal between one or more users, and the smart contracts may be configured to transfer at least one token between the users upon completion of the deal. The system may include communication logic which may be executable by a processor of a client device and configured to communicate data of the smart contract between the client device and the blockchain database. A virtual machine logic may be stored in a memory of a node of the blockchain network. The virtual machine logic may be executable by a processor of the node of the blockchain network and configured to incorporate the data of the smart contract into the blockchain database.

An aspect of the invention relates to a distributed network comprising a plurality of network nodes. The distributed network is configured to perform a method for reaching a consensus on a sequence of values in an advantageous manner. The method performs consecutive notarization rounds. The notarization rounds comprise steps of creating value proposals to be added to the sequence, communicating the value proposals to a notarization subset of the plurality of nodes and performing a validity check of received value proposals. The notarization rounds may comprise further steps of executing individual notarization signatures on a subset of the value proposals that are valid. The notarization rounds may further comprise performing a consistency check of the value proposals and executing consistency signatures on a subset of the value proposals. The method may further comprise a finality procedure to finalize a value proposal once a predefined finality rule set has been fulfilled.

A new interactive method for Barter destined specifically for the rural area, which refers to a new embodiment of token unbacked by computer processing. Where the Barter becomes an operation with tokenized asset associated to marketplaces/hub, social networks, and hubs, in a platform which mixes social network elements with e-commerce, with the purpose of approximating buyers and sellers who use Barter operations and further providing a space for exchange of information, with the creation and facilitating of smart contracts. Where the tokens are used for interactions with producers and suppliers in a marketplace mixed with social media, taking into account the trustfulness generated by the feedback with the social networks.

Systems and methods are disclosed herein for computer-aided method for developing, customizing, and deploying a platform where people can provide service to other users based on a trust among multiple individuals. This is especially useful among ecommerce applications where users can initiate and complete an ecommerce transaction with an individual not directly trusted.

A method for providing interaction information, such as, for example, settlement information, by which a device provides the settlement information to a counterpart device, includes displaying an image which relates to an item to be used for performing the interaction, such as, for example, a credit card image of a credit card of a user of the device, on a lock screen of the device, and receiving a touch input from the user with respect to the credit card image. In the method, settlement information which corresponds to the touched credit card image is used for performing a settlement via the device.
