Solution Overview
Problem
Efficient arithmetization of external events in finite state machines is a significant obstacle in applications that rely on zero-knowledge proofs, leading to high computational costs for proving non-native statements.

Engineering Contradiction Analysis
1Reliability
If external events are directly arithmetized in zero-knowledge proof systems, then proof correctness is maintained, but computational costs become prohibitively high
Solution Approach 1:
The patent introduces a translation chain as an intermediary layer between external events and the zero-knowledge proof system. This translation chain converts external events into a format that is more amenable to arithmetization, thereby reducing computational costs while maintaining proof correctness. The translation chain acts as a mediator that bridges the gap between arbitrary external events and the specific requirements of the proof system.
Solution Approach 2:
The patent performs preliminary translation of external events into a proof-friendly format before they are processed by the zero-knowledge proof system. By pre-processing external events through the translation chain, the system prepares them in advance to be more efficiently arithmetized, reducing the computational burden during the actual proof generation phase.
2Reliability
If complex external events are processed directly by the proof system, then completeness is ensured, but proof generation speed decreases significantly
Solution Approach 1:
The translation chain serves as an intermediary that pre-processes complex external events into a simplified representation that retains all necessary information for complete proofs. This intermediary layer enables faster processing by the proof system without sacrificing completeness, as the translation preserves the essential logical structure needed for verification.
Solution Approach 2:
The patent changes the parameters of external events by transforming them into a different representation format through the translation chain. This parameter transformation converts complex, heterogeneous external events into a standardized, arithmetic-friendly format that the proof system can process more efficiently while maintaining logical equivalence.
3Adaptability or versatility
If arbitrary external events are arithmetized without translation, then generality is maintained, but arithmetization efficiency deteriorates
Solution Approach 1:
The translation chain implements a universal translation mechanism that can handle arbitrary external events while outputting a standardized format optimized for arithmetization. This universal translator maintains the generality of event processing by accepting diverse input types while simultaneously improving arithmetization efficiency by producing a consistent, proof-friendly output format suitable for efficient processing.
