Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Small distributed blockchain ledgers are vulnerable to attacks by a small number of malicious nodes, as traditional consensus methods are insufficient for securing sensitive data.
Innovation Solution
A first node validates all remaining nodes in the ledger using encrypted packages or split-key fragments to generate a common key for secure authentication, eliminating the need for consensus protocols and reducing energy consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional consensus protocols are used in small distributed blockchain ledgers, then nodes can reach agreement on blocks, but the system becomes vulnerable to attacks by a small number of malicious nodes
Solution Approach 1:
The patent extracts the consensus protocol from the security mechanism. Instead of relying on complex consensus protocols to ensure security, the invention uses a simpler approach where nodes are pre-validated and trusted nodes are identified through encrypted package exchange or split-key fragment verification. This separates the consensus function from the security verification function, reducing overall system complexity while maintaining security.
Solution Approach 2:
The patent applies preliminary action by pre-validating nodes before they participate in the blockchain network. Through the use of encrypted packages or split-key fragments, nodes are authenticated in advance, and only validated nodes are allowed to join the distributed ledger. This preliminary validation eliminates the need for complex runtime consensus protocols to ensure security, as trust is established beforehand.
2Reliability
If traditional consensus protocols are used to secure the blockchain, then nodes can validate blocks, but energy consumption increases
Solution Approach 1:
The patent removes the energy-intensive consensus protocol from the security verification process. By using pre-established trust relationships through encrypted packages or split-key fragments, the system eliminates the need for repeated consensus voting and computational proof-of-work, significantly reducing energy consumption while maintaining security.
Solution Approach 2:
The system uses self-service authentication where nodes independently verify each other's credentials through encrypted package exchange or split-key fragment validation. This eliminates the need for energy-intensive centralized consensus mechanisms, as each node can independently verify trustworthiness without consuming excessive energy on consensus participation.
3Productivity
If the number of nodes in the distributed blockchain ledger is small, then the system is more efficient and easier to manage, but it becomes easier to attack
Solution Approach 1:
The patent applies preliminary validation to establish trust relationships before nodes interact in the small distributed ledger. Through encrypted package exchange or split-key fragment verification, each node's authenticity is confirmed in advance. This allows the system to maintain small size for efficiency while ensuring security through pre-established trust, preventing malicious nodes from easily compromising the system.

AI summary
A first node in a distributed blockchain ledger validates all remaining nodes in the distributed blockchain ledger to secure the distributed blockchain ledger. The remaining nodes in the distributed blockchain ledger can be validated in various ways. For example, an encrypted package can be exchanged to obtain a unique session key for each of the remaining nodes in the distributed blockchain ledger. Another alternative is to receive split-key fragments from all the nodes in the distributed blockchain ledger. The received split-key fragments are used to generate a common key for validating all the remaining nodes in the distributed blockchain ledger.
