Abstract: A system and method for verifying a cryptographic transaction includes requesting a portion of the blockchain comprising a merkle tree path; verifying a value of the cryptocurrency key using simplified payment verification; and bundling the cryptographic transaction, a block header of the cryptographic transaction, a plurality of block headers subsequent the block header of the cryptographic transaction, and the merkle tree path thereby forming a cryptographic currency receipt.

Abstract: A system and method implementing secure radio communications in a decentralized network includes: a handshake with one other of the plurality of nodes; establishing a point-in-time reference parameter during the handshake, wherein the point-in-time reference parameter is identified at the end of the handshake with the one other node; identifying a window in randomly sequence of rotating windows based on the point-in-time reference parameter, wherein the identified window contains a channel for conducting an encrypted communication with the one other node; and establishing the communication channel with the one other node.

Abstract: A system and method for facilitating a transaction involving an autonomous device includes: receiving a transaction request from the initiating party; generating an addendum based on the transaction request; validating the one or more requests in the addendum by referencing the one or more claims in the exhibit; digitally signing the addendum by the autonomous transacting device with a cryptographic key and by the initiating transacting device with a cryptocurrency key; verifying a value of the cryptocurrency key; and performing the one or more requests of the transaction request based on the digitally signed addendum and once the value of the cryptocurrency key is verified.

Abstract: A system and method for facilitating microtransaction involving an autonomous transacting device includes generating a plurality of key pairs and sharing a key of each of the plurality of key pairs with the transacting entity; establishing an escrow at the blockchain and providing the plurality of key pairs to the blockchain; exchanging one or more of the key pairs using a sidechain; requesting a release or a refund of funds from the escrow; and presenting one or more exchange key pairs to the blockchain thereby establishing a percent completion of the sidechain.
