    Abstract: A method includes establishing a first funds transfer account associated with a first device and a second funds transfer account with a second device, funding at least the first fund account, and selecting the second device as the recipient of a funds transfer from the first device. The method further includes sending a communications link request from the first device to the second device and receiving acceptance of the communications link request from the second device. The method then establishes a communications link between the first device and the second device, initiates a funds transfer from the first device to the second device, wherein the amount is designated at the first device, and verifies the funds transfer amount, the first funds transfer account, and the second funds transfer account. Then, the method transfers the amount to the second funds transfer account associated with second device.

    Abstract: A system and method for enabling cryptographically sealed (encrypted) auction bids for one or more items, from one or more bidders, based on an Elliptic-Curve Diffie-Hellman (ECDH) cryptographic key exchange on a blockchain-based smart contract. A Diffie-Hellman key exchange is a method for securely exchanging cryptographic keys over a public channel, and allows two parties that have no prior knowledge of each other to jointly establish a shared secret—a value known only to the parties involved in the exchange but not to any eavesdropper. This shared secret can be then used as a key to encrypt subsequent communications, such as a specific bid, using a symmetric-key cipher.
