There is discussed a method of authorising an electronic transaction in which a user device receives a shared secret and a shared secret identifier. Subsequently, on receipt of transaction data from a transaction terminal, the user device calculates a one-way hash of data comprising the shared secret to generate a hash value, generates authentication data comprising the hash value and the shared secret identifier, and transmits the authentication data to the transaction terminal.

The disclosed embodiments include systems and methods for executing a point of sale deposit. In one embodiment, a system may include one or more memory devices storing software instructions, and one or more processors configured to execute the software instructions to receive transaction information related to a point of sale deposit from a client device, and generate a pending deposit transaction based on the transaction information. The one or more processors may be further configured to execute the software instructions to receive a first transaction token from the client device, receive a second transaction token from a third-party device, match the first transaction token to the second transaction token, and complete the pending deposit transaction based on the match.

There may be provided a computer-implemented method. It may be implemented using a blockchain such as, for example, the Bitcoin blockchain. The computer-implemented method includes: i) joining a congress by transferring, by a node operating in a proof-of-work blockchain network, one or more digital assets to a congress pool having one or more other digital assets associated with other members of a congress; ii) detecting, by the node, a special transaction of digital assets on the proof-of-work blockchain network to an address associated with the congress pool, the special transaction satisfying determined criteria; and iii) minting, by the node, one or more digital assets on a proof-of-stake blockchain network in response to detecting the special transaction.

Disclosed in some examples are devices, systems, and machine readable mediums for establishing peer to peer mobile wallet communications (P2PMW) over short range wireless communication networks. These P2PMW communications allow exchange of information between two wallet clients. Example communications include payments, providing identification, providing loans, and the like. The use of P2PMW communications opens up the prospect of anyone accepting payment from anybody else at any time. All that is needed is a computing device with a mobile wallet. Example short range wireless communications include Wireless LANs (WLAN) such as WIFI (e.g., communicating according to an Institute for Electrical and Electronics Engineers (IEEE) 802.11 family of standards), BLUETOOTH® or the like.

A high-performance distributed ledger and transaction computing network fabric over which large numbers of transactions (involving the transformation, conversion or transfer of information or value) are processed concurrently in a scalable, reliable, secure and efficient manner. In one embodiment, the computing network fabric or “core” is configured to support a distributed blockchain network that organizes data in a manner that allows communication, processing and storage of blocks of the chain to be performed concurrently, with little synchronization, at very high performance and low latency, even when the transactions themselves originate from distant sources. This data organization relies on segmenting a transaction space within autonomous but cooperating computing nodes that are configured as a processing mesh. Each computing node typically is functionally-equivalent to all other nodes in the core. The nodes operate on blocks independently from one another while still maintaining a consistent and logically-complete view of the blockchain as a whole. According to another feature, secure transaction processing is facilitated by storing cryptographic key materials in secure and trusted computing environments associated with the computing nodes to facilitate construction of trust chains for transaction requests and their associated responses.

Various examples are directed to systems and methods for authentication transactions. A mobile computing device may send to a financial institution system, an access request message. The mobile computing device may receive from a second server system, a transaction request message requesting authorization for a transaction on an account associated with the mobile computing device, the transaction request including a transaction amount. The mobile computing device may prompt a user of the mobile computing device to authorize the transaction. The mobile computing device may receive, from the financial institution system, summary data describing the transaction amount.
