Solution Overview

Problem

Conventional electronic systems for managing cryptocurrencies and smart contracts lack effective safeguards against hacking, particularly in protecting private keys and account information, leading to vulnerabilities that can result in theft of entire repositories of digital currencies.

Innovation Solution

A secure electronic system utilizing a combination of hot and cold memory modules, where hot modules are accessible for transactions and can be powered down, and cold modules are immutable and inaccessible, along with a non-IP protocol for secure communication, signature verification, and rate limiting to prevent unauthorized access and fraudulent transactions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If private keys and account information are stored in conventional electronic systems for cryptocurrency management, then access and transaction speed are improved, but security against hacking is worsened

Engineering Contradiction:
Improveaccess speedVSAvoidsecurity against hacking
Core Design Contradiction:
SpeedVSReliability

Solution Approach 1:

The patent segments the cryptocurrency storage system into multiple independent memory modules (first memory module, second memory module, third memory module) with different security characteristics. The second memory module stores private keys in an immutable manner, while other modules handle transaction processing. This segmentation allows the system to maintain both fast access speeds for transactions and high security for key storage by isolating critical security functions in a dedicated, immutable module.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If private keys are made accessible for transactions, then ease of operation is improved, but vulnerability to theft is worsened

Engineering Contradiction:
Improvetransaction accessibilityVSAvoidtheft vulnerability
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent implements preliminary action by pre-configuring the second memory module with immutable storage characteristics before private keys are stored. The module is designed with fixed, non-modifiable memory structures that prevent any future alterations or unauthorized access. This preliminary setup ensures that when private keys are made accessible for transactions through the exchange system, they remain protected by the pre-established immutable barrier, allowing ease of operation without increasing theft vulnerability.

Inventive Principle:
Principle #10Preliminary action

3Productivity

If cryptocurrency repositories are made accessible for transactions, then productivity is improved, but risk of large-scale theft is worsened

Engineering Contradiction:
Improvetransaction throughputVSAvoidlarge-scale theft risk
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces an intermediary exchange system that mediates between the immutable second memory module storing private keys and the external transaction network. The exchange system handles all transaction processing, validation, and execution without requiring direct access to the immutable key storage. This intermediary architecture enables high transaction throughput and productivity while preventing large-scale theft, as the intermediary controls and monitors all access to the cryptocurrency repositories, blocking any unauthorized bulk access attempts.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A secure electronic system for storing and managing receipt and releasing of electronic documents, such as cryptocurrencies, digital currencies, tokens, and smart contracts, includes a platform server, a secure computer, and a non-IP protocol for communication between the secure computer and the platform server. The secure computer includes a plurality of cold memory modules and at least one hot memory module. The secure computer powers up and makes hot one or more of the plurality of the cold memory modules upon detecting and empty condition or a full condition. The secure computer includes a rate limiter that restricts releasing of hot electronic documents, such as cryptocurrencies, digital currencies, tokens, and smart contracts, stored in the at least one hot memory module. The non-IP protocol is known only to authorized administrators or operators of the secure electronic system. The secure computer provides access to the platform server only through the non-IP protocol.
