Back-Step Blockchain Inversion for Energy Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current blockchain technologies rely on energy-intensive Proof of Work and require distributed networks, making them inefficient and vulnerable to manipulation, especially in scenarios where high transaction speeds and secure, localized data integrity are needed.
Innovation Solution
The Back-Step Blockchain (BSB) method eliminates the need for Proof of Work by using back-step values and back-step seal values, which are calculated using one-way functions, allowing for fast, secure, and localized blockchain operations without the need for distributed nodes, enabling high-speed transactions and easy detection of manipulations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If Proof of Work is used to secure blockchain, then security and manipulation detection are improved, but energy consumption increases significantly
Solution Approach 1:
The patent inverts the traditional blockchain approach by using backward chaining instead of forward chaining. Instead of computing hashes forward through the chain (which requires Proof of Work), the system computes hashes backward from the current block to previous blocks, eliminating the need for energy-intensive Proof of Work while maintaining security and manipulation detection capabilities.
2Reliability
If distributed nodes are used to prevent manipulation, then security is improved, but system complexity and device size increase
Solution Approach 1:
The patent extracts the security function from the distributed network paradigm. By implementing backward chaining with cryptographic hashes, the system achieves security properties traditionally requiring distributed nodes without actually needing them. The security mechanism is extracted and embedded within the block structure itself, enabling single-node operation.
Solution Approach 2:
The blockchain system becomes self-verifying through backward chaining. Each block automatically contains cryptographic proof of its relationship to previous blocks, allowing any single node to independently verify the entire chain's integrity without requiring coordination with or validation from other distributed nodes.
3Reliability
If Proof of Work is used to secure blockchain, then manipulation detection is improved, but transaction speed decreases
Solution Approach 1:
The patent inverts the computational approach from forward-hashing (which requires iterative Proof of Work) to backward-hashing. This inversion enables rapid computation of block relationships without the iterative guessing process of Proof of Work, significantly increasing transaction throughput while maintaining manipulation detection through cryptographic verification.
4Reliability
If large number of nodes are used in network, then security against manipulation is improved, but computational workload increases
Solution Approach 1:
The patent extracts the security verification function from the network layer and embeds it within the block data structure itself. Each block contains its own cryptographic proof through backward chaining, allowing security verification to be performed locally without requiring computational resources to be distributed across multiple network nodes.

AI summary
Method to create trust for blockchains without the need for Proof-of-Work and without the need for multiple contributing nodes. The method comprises one or more, backward chained elements in each block. These elements have a one-way property from the current block to the previous block. The invention can be implemented in Hardware, Software or in a combination of both. Embodiments of the back-step blockchain comprise existing blockchain applications and new blockchain application where speed or physical size or network independency are desired properties. One, but not the only embodiment is the implementation of the back-step blockchain into smartphones.
