Solution Overview

Problem

Existing cryptocurrency systems using bonding curves are vulnerable to attacks when updating exchange functions, as an increased annulment exchange function can create a window for attackers to convert excess tokens before and after the update, leading to potential system exploitation.

Innovation Solution

A method is implemented to verify if a proposed update in exchange functions introduces vulnerabilities by computing attack amounts of tokens and comparing them to determine if an attacker can exploit the system, allowing for the selection of intermediate exchange functions and gradual updates to mitigate risks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the annulment exchange function is increased to handle surplus tokens, then the system can manage token supply better, but a vulnerability window is created allowing attackers to exploit the system

Engineering Contradiction:
Improvetoken supply managementVSAvoidsystem security
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The system performs preliminary security analysis by computing attack amounts before applying the updated exchange function. The vulnerability detection mechanism calculates how many tokens an attacker could obtain using the old exchange function and compares it against the new exchange function's output, preventing unsafe updates from being deployed

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system implements feedback by continuously monitoring and comparing attack amounts against security thresholds. After computing the attack amount using the new exchange function, the system checks whether the attack amount exceeds a predefined threshold, and only allows the update if security requirements are satisfied

Inventive Principle:
Principle #23Feedback

2Adaptability or versatility

If exchange functions are updated frequently to adapt to market conditions, then system flexibility improves, but the risk of introducing vulnerabilities increases

Engineering Contradiction:
Improvemarket adaptationVSAvoidvulnerability introduction
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

Before any exchange function update is applied, the system performs preliminary computation of attack amounts using both the old and new exchange functions. This advance analysis ensures that potential vulnerabilities are identified and prevented before the update takes effect

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The vulnerability detection mechanism acts as an intermediary between the update process and the actual application of new exchange functions. It computes attack amounts, compares them against security thresholds, and mediates whether the update should be allowed, blocked, or requires additional measures

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If a security analysis of exchange function updates is implemented, then system security improves, but computational complexity and processing time increase

Engineering Contradiction:
Improvesecurity verificationVSAvoidcomputational complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system replaces complex cryptographic security verification with a simplified mathematical approach using exchange function computations. Instead of performing full cryptographic analysis, the system computes attack amounts directly from the exchange functions and compares them against thresholds, significantly reducing computational complexity

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

AI summary

Some embodiments are directed to a computer-implemented method for determining a vulnerability in a new exchange function for use in a cryptocurrency system. An attack amount of crypto tokens of the first type (413) and a first attack amount of crypto tokens of the second type (414) may be obtained, wherein the attack amount of crypto tokens of the first type (413) can be obtained according to a first creation exchange function (410) in exchange for the first attack amount of crypto tokens of the second type (414). A second attack amount of crypto tokens of the second type (433) is obtainable in exchange for the attack amount of crypto tokens of the first type (413). If the second attack amount of crypto tokens of the second type (433) exceed the first attack amount of crypto tokens of the second type (414) by more than a threshold, a vulnerability is found.
