Solution Overview

Problem

Existing blockchain systems have limited scripting capabilities, restricting the range of hash functions that can be implemented, and current hash functions are computationally expensive, making it desirable to expand the range of hash functions while maintaining stability and trustworthiness.

Innovation Solution

A computer-implemented method using blockchain transactions to generate a hash function by performing specific mathematical operations, such as multiplication, addition, and modulo operations, to create a new hash result, which is less computationally expensive and can be used in place of existing hash functions like OP_HASH160.

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent creates a universal hash function implementation that can serve multiple purposes within the blockchain system - generating addresses, creating hashes for transaction data, and potentially other cryptographic applications. This single versatile function reduces the need for multiple specialized hash functions.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent segments the hash function implementation into distinct mathematical operations (multiplication by first parameter, addition of second parameter, modulo by third parameter) that can be independently executed and verified. This segmentation makes the complex function more manageable and easier to validate within the scripting language.
