Patent application blockchain wallets cost money. QNC files patent to minimize costs.
A new type of blockchain wallet is proposed, having a combination of more than one key generation scheme (e.g., HD and ND key generation schemes). The wallet utilizes a selection module (or “selector”) which evaluates different cost parameters and selects a key generation architecture to optimize overall cost of the wallet. Moreover, QRNG may be used for randomness, rendering any brute force attack impossible due to very high entropy.
The Memory Utilization Cost refers to the price set by hardware manufacturers for memory hardware that needs to be embedded and extended on a blockchain wallet device.
The latency cost incurs when users intend to generate a key and send a transaction to the network, the latency of key generation can incur a financial cost to them, i.e., the user is unable to trade for the time key is being generated and transaction is sent. e.g., some fast-paced scenarios, i.e., automatic trading may require actions during the key generation interval.
The security cost represents the monetary risk involved with the security of the system. The security cost need be minimized in order to protect end-user’s assets. The security cost is further expanded into two elements: the unlinkability cost and the unforgeability cost.
