Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing contract management systems are inefficient, prone to synchronization issues, and lack secure, automated execution and enforcement mechanisms, leading to security and cost inefficiencies.
Innovation Solution
Implementing a deterministic finite automaton (DFA) on a blockchain infrastructure to automate and enforce contract execution, using unspent transaction outputs (UTXOs) to record and transition states, and utilizing blockchain transactions to manage state changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If contracts are manually maintained with local stores and copies, then flexibility in contract management is maintained, but synchronization issues arise and security risks increase
Solution Approach 1:
The patent merges multiple contract copies stored locally across different parties into a single centralized smart contract deployed on the blockchain. This eliminates synchronization issues between local copies while maintaining the ability for all parties to access and verify the same contract state, thereby improving reliability without significantly increasing complexity.
Solution Approach 2:
The blockchain acts as an intermediary layer that hosts the smart contract, mediating between all contracting parties. Instead of parties directly managing their own copies and coordinating changes, the blockchain intermediary automatically maintains the single source of truth, reducing the complexity of manual coordination while enhancing execution reliability.
2Productivity
If smart contracts are automated on blockchain, then execution efficiency and security are improved, but system complexity and implementation difficulty increase
Solution Approach 1:
The smart contract is designed to be self-executing and self-enforcing on the blockchain. Once deployed, the contract automatically processes transactions and enforces terms without requiring manual intervention or complex external management systems. This automation dramatically improves execution efficiency while the standardized blockchain environment keeps implementation complexity manageable.
Solution Approach 2:
The patent employs a universal smart contract platform (blockchain) that can handle multiple types of contracts and transactions through a standardized framework. This multi-functionality allows the system to improve productivity across various contract types without requiring separate complex systems for each, as the blockchain provides a unified execution environment.
3Reliability
If multiple local copies of contracts are maintained, then accessibility is improved, but synchronization and security problems arise
Solution Approach 1:
While the patent maintains a single source of truth on the blockchain, it allows unlimited parties to simultaneously access and verify the contract state without creating separate editable copies. This copying approach ensures all users have convenient access to the same consistent data while preventing the synchronization and security issues that arise from maintaining multiple writable local copies.
4Loss of energy
If manual contract management is used, then implementation simplicity is maintained, but cost efficiency and reliability deteriorate
Solution Approach 1:
The patent replaces manual mechanical contract management processes with automated smart contract execution on the blockchain. This substitution eliminates the need for manual tracking, verification, and enforcement activities, significantly reducing management costs while simultaneously increasing the extent of automation. The blockchain infrastructure provides this automation without requiring complex additional systems.

AI summary
The invention relates to a technique for implementing, controlling and automating a task or process on a blockchain such as, but not limited to, the Bitcoin blockchain. The invention is particularly suited for, but not limited to, automated execution of contracts such as smart contracts for financial agreements. However, other types of tasks and non-financial contracts can be implemented. The invention can be viewed as the implementation or incarnation of a state machine or DFA on a blockchain by using the unspent outputs of blockchain Transactions to represents the states of the machine, and spending of those outputs as the transition of the machine from one state to another. The invention provides a technical realisation and implementation of a mathematical model of computation conceived as an abstract machine that can be in one of a finite set of states, and can change from one state to another (transition) when a triggering event of a finite set (called input) occurs. The invention comprises compilation and codification techniques for the DFA implementation.
