Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Proof of Space (PoS) based mining systems face challenges such as high storage requirements that exclude small players, mining pool fraud, and grinding attacks, which are not effectively addressed by existing technologies, leading to inequitable and unsustainable cryptographic currency systems.
Innovation Solution
A PoS based mining system that controls the success of mining for operators of different sizes without favoring larger capacity operators, using a quality assessment function to validate challenges and responses, and employing Merkle signatures and trees to secure and verify ledger entries, thereby preventing grinding and fraud.

Engineering Contradiction Analysis
1Use of energy by moving object
If Proof of Space based mining is used to reduce energy consumption, then energy consumption is reduced, but storage requirements become excessively high excluding small players
Solution Approach 1:
The patent divides the storage proof into two distinct phases: a setup phase where miners allocate and register their storage space, and a mining phase where challenges are issued and responses are verified. This segmentation allows the system to verify storage presence without requiring continuous verification of entire storage datasets, thereby reducing the storage burden on miners while maintaining security.
Solution Approach 2:
The patent introduces a verifier that acts as an intermediary between miners and the system. The verifier issues challenges and validates responses without requiring direct access to or verification of the entire storage dataset. This intermediary approach allows the system to confirm storage proof with minimal storage requirements from the miner's perspective.
2Reliability
If large storage capacity is required for PoS mining, then mining security is improved, but smaller mining operators are excluded from participation
Solution Approach 1:
The patent implements local quality by tailoring the mining challenge and verification parameters to the specific storage capacity of each miner. Miners with different storage allocations receive appropriately scaled challenges, allowing small miners to participate securely without being outcompeted by large miners. The system adjusts verification requirements locally based on individual miner capabilities.
Solution Approach 2:
The patent introduces dynamic difficulty adjustment where the mining challenge parameters are adjusted based on the miner's storage capacity and the current state of the network. This dynamic approach ensures that miners of all sizes have a fair chance of success while maintaining overall system security, as the difficulty scales with the miner's resources rather than requiring fixed high storage requirements.
3Productivity
If mining success is controlled by storage capacity, then larger operators are favored, but system fairness and sustainability are compromised
Solution Approach 1:
The patent implements equipotentiality by ensuring that all miners, regardless of storage capacity, have an equal probability of success in the mining process. The challenge-response mechanism is designed so that the difficulty is adjusted relative to each miner's storage allocation, creating a level playing field where storage capacity translates proportionally to mining success probability rather than creating unfair advantages for large operators.

AI summary
A verifying entity of a decentralized system is configured to receive information associated with at least one ledger entry of a distributed ledger of the decentralized system, to verify at least a portion of one or more computations associated with the received information, to generate evidence of at least one error in the at least a portion of the one or more computations associated with the received information, and to associate the generated evidence with a public key of the verifying entity. The decentralized system may comprise a proof of space based mining system, and the at least one ledger entry of the distributed ledger may comprise at least one proof of space for the proof of space based mining system.
