Secure Crossing Network for Private Asset Transfers

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current systems for transferring digital assets between blockchains are often costly due to high transfer fees and may not support cross-chain transfers, and secure computing environments struggle to protect transactions from malicious actors and operator interference.

Innovation Solution

A secure crossing network within a trusted execution environment, utilizing a secure enclave to facilitate private and anonymous transactions by loading the crossing network program into secure memory, generating validation values, receiving orders, matching them, and determining reference prices based on external market data, while ensuring the code's authenticity and security through remote attestation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of substance

If assets are transferred through public exchanges, then transfer can be supported, but transfer fees are high and transactions are not private

Engineering Contradiction:

Improvetransfer feesVSAvoidtransaction security and privacy

Core Design Contradiction:

Loss of substanceVSReliability

Solution Approach 1:

The system segments the transfer process into two parts: public exchange for price discovery and private crossing network for actual execution. This allows users to benefit from both public market pricing and private, low-fee transfers by matching orders off-exchange while referencing exchange prices.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The crossing network acts as an intermediary between public exchanges and users, enabling private order matching while using exchange price data as reference. This intermediary layer provides anonymity and low fees while maintaining market connection through oracle-based price feeds.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Device complexity

If crossing network operates without secure enclave, then operation is simpler, but it is vulnerable to operator interference and malicious actors

Engineering Contradiction:

Improvesystem structureVSAvoidprotection from malicious actors

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The system combines traditional crossing network functionality with hardware-based secure enclave technology (Intel SGX). This composite architecture merges the simplicity of crossing networks with the security properties of trusted execution environments, creating a system that is both operationally simple and cryptographically secure.

Inventive Principle:

Principle #40Composite materials

3Loss of information

If crossing network is completely private, then anonymity is maintained, but market connection and pricing accuracy deteriorate

Engineering Contradiction:

Improvetransaction anonymityVSAvoidpricing accuracy

Core Design Contradiction:

Loss of informationVSMeasurement precision

Solution Approach 1:

The system implements feedback loops where oracle components continuously fetch price data from public exchanges and feed it into the crossing network. This ensures that while transactions remain private, they are continuously anchored to current market prices, maintaining pricing accuracy without compromising anonymity.

Inventive Principle:

Principle #23Feedback

4Adaptability or versatility

If cross-chain transfers are enabled, then asset mobility increases, but transfer fees become prohibitively expensive

Engineering Contradiction:

Improvecross-chain transfer capabilityVSAvoidtransfer fees

Core Design Contradiction:

Adaptability or versatilityVSLoss of substance

Solution Approach 1:

The system merges multiple blockchain assets into a unified crossing network environment where they can be traded without cross-chain transfer fees. By consolidating different blockchain assets in one secure enclave environment, users can exchange assets across chains through the crossing network rather than paying expensive cross-chain bridge fees.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

In one implementation, a system to provide a secure crossing network for trading digital blockchain assets outside of an exchange can include a crossing network program that is configured to provide a crossing network for the digital blockchain assets and a computer system with a secure enclave that is configured to provide the trusted execution environment within which processing of programs is secure from observation and manipulation by other operations outside of the secure enclave. The execution of the crossing network program in the secure enclave receiving, from client devices, crossing network orders to trade assets within the crossing network; matching at least a portion of the crossing network orders in an order book; obtaining, using a pricing oracle, pricing information for transactions in the exchange; and determining a reference price for the matched orders within the crossing network based on the pricing information from the exchange.
