Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Smart contracts on blockchain networks face inefficiencies in relying on oracles for off-chain data, leading to high computational and transactional costs in validating and executing token transfers.
Innovation Solution
A system where a custodial token platform generates and verifies transfer requests, allowing smart contracts to validate and swap crypto tokens on-chain without relying heavily on oracle calls, enabling high-speed and low-cost token transfers between senders and recipients.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If smart contracts rely on oracles for off-chain data validation, then transfer accuracy can be maintained, but computational costs and transactional fees increase significantly
Solution Approach 1:
The patent extracts the data validation function from the smart contract and relocates it to the message sender. The sender is responsible for providing accurate off-chain data and proving its validity, rather than the smart contract needing to verify it through expensive oracle calls. This separation reduces the computational burden on the blockchain network while maintaining transfer accuracy through cryptographic proofs and economic incentives.
Solution Approach 2:
The system implements self-service validation where the message sender independently provides and proves the validity of off-chain data without requiring external oracle services. The sender uses their own resources to generate cryptographic proofs (such as zk-SNARKs or other zero-knowledge proofs) that validate the data, eliminating the need for costly third-party verification and reducing overall system dependency on oracles.
2Measurement precision
If smart contracts rely on oracles for off-chain data validation, then data accuracy can be ensured, but transactional fees and execution time increase
Solution Approach 1:
The patent implements preliminary validation where the sender prepares and attaches cryptographic proofs of data validity to the transfer message before submitting it to the smart contract. This pre-validation approach eliminates the need for time-consuming oracle verification during transaction execution, as the data accuracy is already established through cryptographic evidence included in the message itself.
3Adaptability or versatility
If multiple crypto token types are supported with flexible swaps, then system versatility improves, but device complexity increases
Solution Approach 1:
The patent implements a universal transfer message format and standardized validation mechanism that works across multiple crypto token types. The smart contract uses a generic interface for handling different tokens, where the sender provides token-specific information that conforms to a standardized structure. This allows the system to support diverse token types (ERC-20, ERC-721, ERC-1155, etc.) through a single unified contract without requiring separate complex validation logic for each token standard.
Data Source
AI summary
Methods, systems, and devices for data management are described. A self-executing program of a blockchain distributed data store may receive a first message that includes indications of a sender address and a first amount of a first crypto token type to be received by a recipient address. The self-executing program may verify based at least in part on execution of the self-executing program, that the first message is validly signed by an operator associated with the self-executing program. The operator may be associated with a custodial token platform that verifies information and signs messages. The self-executing program may broadcast, after verifying that the first message is validly signed, one or more second messages that are configured to transfer the first amount of the first crypto token type to the recipient address.
