Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Blockchain networks face scalability issues, with high transaction fees and low throughput, leading to inefficiencies in processing transactions, and there is a trade-off between transaction speed and decentralization, making it difficult to maintain both high scalability and security.
Innovation Solution
A method and system for dynamically tuning blockchain parameters to achieve desired levels of decentralization, scalability, and security without hard forks, using adaptive approaches for on-chain and off-chain scaling, and synchronizing transactions between private and public blockchains to reduce fees and increase throughput.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If block-time is reduced to process transactions faster, then transaction throughput is improved, but network security deteriorates
Solution Approach 1:
The patent segments the blockchain network into multiple parallel chains (sharding), where each chain processes a subset of transactions independently. This allows the network to increase overall throughput by distributing transaction processing across multiple chains while each chain maintains its own security through standard block-time intervals, thus resolving the contradiction between speed and security.
Solution Approach 2:
The patent introduces a new dimension by creating off-chain transaction processing mechanisms (such as state channels and rollups) that operate parallel to the main blockchain. These off-chain mechanisms handle transactions without requiring every transaction to be confirmed on the main chain, thereby increasing throughput while the main chain maintains security through its established consensus mechanism and block-time.
2Productivity
If block-size is increased to process more transactions per block, then transaction throughput is improved, but device complexity increases
Solution Approach 1:
The patent divides the blockchain into multiple smaller chains (shards), each handling a portion of the total transaction load. This segmentation allows each individual chain to maintain a manageable block-size and complexity while the aggregate system achieves high throughput across all chains combined, avoiding the complexity of a single large blockchain.
Solution Approach 2:
The patent introduces intermediary layers such as sequence headers and cross-chain communication protocols that coordinate between multiple shard chains. These intermediaries manage the complexity of having multiple chains by providing standardized interfaces for transaction routing, state synchronization, and consensus coordination, thereby reducing the overall system complexity while maintaining high throughput.
3Reliability
If multiple confirmations are required to secure transactions, then network security is improved, but transaction latency increases
Solution Approach 1:
The patent implements partial confirmations by allowing transactions to be considered secure after a certain number of confirmations on their respective shard chains, without requiring all chains to reach the same confirmation depth. This partial action approach reduces the time required for transactions to be considered secure while maintaining adequate security through the distributed nature of the sharded network.
Solution Approach 2:
The patent uses preliminary actions by pre-establishing security deposits and locked funds in smart contracts before transactions occur. This allows the network to provide security guarantees upfront through bonding mechanisms, reducing the need for multiple sequential confirmations and thereby decreasing transaction latency while maintaining security through the pre-deposited collateral.

AI summary
A method of synchronizing transactions between blockchains including receiving a first plurality of transactions and recording the first plurality of transactions to a first private block on a private blockchain network, receiving a second plurality of transactions and recording the second plurality of transactions to a second private block on the private blockchain network, generating a first merged block comprising the first private block and the second private block, recording the first merged block to a single block on a second blockchain network, recording each of the first private block, the second private block, and the first merged block to a smart contract linked to the private blockchain network, defining a private smart contract, and performing a synchronization process between the first private smart contract and a second smart contract linked to the second blockchain network, defining a second smart contract.
