Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Transferring cryptocurrency via blockchain is delayed and costly, typically taking minutes to hours and incurring fees of a few cents to dollars per transaction.

Innovation Solution

The method involves wrapping a cryptocurrency wallet in a digital note, which is encrypted and transferred using a digital note/collateral server, enabling fast and secure transactions through the generation and transfer of encrypted digital notes and collaterals.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If cryptocurrency is transferred via blockchain, then the transfer is secure and verifiable, but the transaction time is long (minutes to hours) and costs are high (cents to dollars per transaction)

Engineering Contradiction:

Improvetransaction speedVSAvoidtransaction time

Core Design Contradiction:

SpeedVSLoss of time

Solution Approach 1:

The patent segments the cryptocurrency transfer process into two distinct layers: (1) a fast local transfer layer using digital notes that operates independently of the blockchain, and (2) a periodic settlement layer that batches transfers to the blockchain. This segmentation allows most transactions to occur rapidly without blockchain delays, while maintaining security through periodic blockchain anchoring.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces digital notes as an intermediary representation of cryptocurrency value. These digital notes can be transferred instantly between parties without requiring blockchain confirmation, while the underlying cryptocurrency settlement occurs periodically on the blockchain. This intermediary layer decouples the speed of transfer from the speed of final settlement.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If cryptocurrency is transferred via blockchain, then the transfer is secure and verifiable, but the transaction costs are high (cents to dollars per transaction)

Engineering Contradiction:

Improvetransfer securityVSAvoidtransaction cost

Core Design Contradiction:

ReliabilityVSLoss of energy

Solution Approach 1:

The patent segments the transfer cost structure by separating the frequent, low-value digital note transfers (which have minimal cost) from the periodic, batched blockchain settlements. This allows the majority of transactions to occur with negligible cost, while security is maintained through the periodic anchoring to the secure blockchain layer.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Digital notes serve as a low-cost intermediary that represents cryptocurrency value for日常 transactions. The expensive blockchain infrastructure is used only for periodic settlement and verification, not for every individual transfer. This dramatically reduces the average cost per transaction while preserving the security guarantees of blockchain for the underlying asset.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A digital note includes a note ID, a crypto currency wallet address, a crypto currency amount, and an encrypted digital note (EDN) associated with the digital note. The EDN includes the note ID, the crypto currency wallet address, the crypto currency amount, and a crypto currency wallet private key or a portion of the crypto currency wallet private key that are encrypted together.
