Solution Overview

Problem

The immutability and irreversibility of transactions on blockchain systems pose security risks, such as vulnerability to malicious attacks and inability to recover tokens lost due to fraudulent activities, which negatively impact transaction security and trust.

Innovation Solution

A method involving a global token pool where tokens from multiple wallets are aggregated, allowing users to exchange a first type of token for a second type, with the option for tokens to be in a recoverable state, enabling reversible transactions and maintaining a continuous supply of tokens, thus reducing computational expenses and enhancing security.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If transactions are made immutable and irreversible on blockchain, then trust and security between unknown parties is established, but vulnerability to malicious attacks increases and ability to recover lost tokens decreases

Engineering Contradiction:

Improvetrust establishmentVSAvoidvulnerability to malicious attacks

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent segments the transaction process into multiple states (pending, confirmed, reversed) and multiple layers (blockchain layer, application layer). By separating the immutable blockchain record from the reversible application-level transaction state, the system maintains blockchain reliability while enabling attack mitigation through state management and recovery mechanisms.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent implements preliminary actions by establishing transaction pending states before final confirmation, creating recovery windows before transactions become fully irreversible. This allows the system to prepare reversal mechanisms and security measures in advance, enabling response to malicious attacks before they become permanent.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If tokens are exchanged directly between wallets on blockchain, then transaction security is maintained through immutability, but computational resources and time increase due to additional verification transactions

Engineering Contradiction:

Improvetransaction securityVSAvoidtransaction execution efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent introduces a smart contract intermediary that manages token exchanges between wallets. This intermediary handles the exchange logic, state management, and reversal operations, reducing the computational burden on the blockchain for each individual transaction while maintaining security through the immutable smart contract code.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent merges multiple transaction operations into a single smart contract execution. By combining exchange, state management, and reversal logic into one unified contract, the system reduces the number of separate blockchain transactions needed, thereby improving execution efficiency while maintaining security.

Inventive Principle:

Principle #5Merging (Combining)

3Adaptability or versatility

If multiple types of tokens are used for transactions, then versatility of the blockchain system is improved, but complexity of token exchange and supply management increases

Engineering Contradiction:

Improvetoken exchange capabilityVSAvoidtoken supply management

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent creates a universal smart contract that can handle multiple token types through a standardized interface. The contract maintains a unified state management system that tracks different token types and their supplies, enabling versatile token exchange while managing complexity through a single multi-functional contract rather than separate contracts for each token type.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

Certain aspects provide techniques and apparatus for efficiently executing reversible transactions on a blockchain. An example method generally includes aggregating tokens from a plurality of wallets into a global pool of tokens. Generally, the global pool of tokens comprises a first type of token and a second type of token. A request to exchange a first quantity of the first type of token stored in a wallet to a second type of token is received. A second quantity of the second type of token to transfer to the wallet is calculated based, at least in part, on a ratio of the first type of token to the second type of token in the global pool of tokens. The first quantity of the first type of token is transferred to the global pool of tokens, and the second quantity of the second type of token is transferred to the wallet.
