Abstract: Blockchain supported resource transfer communication protocol techniques are described. In an implementation, a semantic message is received encoding parameters to be implemented as part of a resource transfer involving a digital wallet. A quote is generated specifying attributes as part of implementing communication connections to perform the resource transfer in compliance with the parameters specified by the semantic message. An acceptance message is received indicating acceptance of the quote, the acceptance message including credentials of the digital wallet. Generation is initiated of an application executable as part of a blockchain as complying with the parameters and the attributes. Data describing the application as executable as part of the blockchain is transmitted for distribution to the digital wallet. The resource transfer is initiated through execution of the application as part of the blockchain.

Abstract: A system has a first electronic device with optical sensor, digital radio transceiver, and processor with firmware; this device is typically portable or wearable. The system also has a computerized device with a display, a second digital radio transceiver, and a second processor with firmware. The first and computerized devices are configured to set up a digital radio link when in radio range. The second processor uses a spot on the display to optically transmit a digital message including a secret such as an encryption key or subkey and/or an authentication code adapted for authenticating an encrypting the radio link. The first device receives the digital message via its optical sensor, and uses the digital message to validate and establish encryption on the radio link. In embodiments, the system determines a location of the first device on the display and positions the transmission spot at the determined location.
