Priority Transaction Processing With Signature-Verified Block Inclusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users who occasionally use legal tender for transactions in blockchain systems like Ethereum face challenges in estimating the required amount of ETH due to price fluctuations, leading to risks and difficulties in managing transaction fees, especially during network congestion.
Innovation Solution
An information processing apparatus that includes a memory unit for storing a verification key to verify an electronic signature for priority approval, allowing transactions to be prioritized through the use of a private key, and a processor to generate and publicize blocks that include these prioritized transactions on a distributed ledger.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users constantly keep ETH to pay transaction fees, then transactions can be approved reliably, but users face price fluctuation risks and difficulty in estimating required amounts
Solution Approach 1:
The patent introduces a priority selling device as an intermediary between users and the blockchain network. This device sells priority approval rights to transactions, allowing users to guarantee transaction inclusion without needing to hold ETH constantly. The priority selling device acts as a mediator that converts the need for ETH holding into a purchasable service, eliminating price fluctuation risks for ordinary users while maintaining reliable transaction approval.
2Productivity
If users pay higher transaction fees, then transactions are approved preferentially, but fee estimation becomes difficult and costs increase
Solution Approach 1:
The patent implements preliminary action by allowing users to purchase priority approval rights in advance before needing transaction inclusion. The priority selling device sells these rights beforehand, so users don't need to estimate fees at the moment of transaction. This pre-purchase approach eliminates the complexity of real-time fee estimation while ensuring preferential approval when needed.
3Reliability
If network congestion increases, then transaction fees rise, but users cannot predict required ETH amounts
Solution Approach 1:
The patent extracts the ETH holding requirement from the user's operational burden. Instead of users needing to constantly hold and estimate ETH amounts, the system extracts this requirement and replaces it with a priority selling mechanism. Users can purchase priority rights when needed without maintaining ETH balances, separating the transaction inclusion guarantee from the substance holding requirement.

AI summary
An information processing apparatus that processes a priority granting process, the information processing apparatus includes a memory unit that memorizes a verification key for verifying an electronic signature for priority approval generated by using a private key of a priority seller that grants a prioritized approval authority to a transaction. The information processing apparatus further includes a processor which executes a process including verifying using the verification key, an electronic signature given to an unapproved transaction publicized on a distributed ledger, generating when an electronic signature given to the unapproved transaction is verified by the verifying as the electronic signature for priority approval, a block that preferentially includes the unapproved transaction over unapproved transactions to which the electronic signature for priority approval is not given, and publicizing the block on the distributed ledger.
