Abstract: A method of performing cryptocurrency transactions requiring a private key includes: establishing a connection from a smart wallet to a user device; receiving a transaction request requiring the private key; disabling the connection; retrieving the private key to a private key memory; processing the transaction; clearing the private key memory; enabling the connection; and sending a completion message. A method of performing cryptocurrency transactions requiring a private key includes: establishing a connection from a user device to a smart wallet; receiving a transaction request requiring the private key; sending the transaction request to the smart wallet; determining that the smart wallet is disconnected from the user device; waiting for the smart wallet to reconnect; and receiving a response from the smart wallet. A smart wallet includes: a storage; a private key storage; and a communication module that is able to communicate with a user device across at least one channel.

Abstract: A streaming media system includes: a source that provides streaming content to a destination across a communication channel, where: the streaming content is sent using a message structure with packets having a first payload size, each packet including at least one streaming payload having a second payload size. An automated method includes: determining a first payload size associated with a communication channel between a source and a destination; determining a second payload size associated with an encoding algorithm used to provide streaming content; determining a maximum number of message types based on the first payload size; and determining a size of an identifier associated with each message. An automated method of providing streaming content includes: receiving streaming content at a source; identifying a message structure; fragmenting the received data based on the message structure; generating an optimized packet using the fragmented data; and sending the optimized packet to a destination.
