Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If Proof-of-Work blockchain is used for decentralized storage, then security and decentralization are improved, but scalability and energy efficiency deteriorate
Solution Approach 1:
The patent transitions from Proof-of-Work to Proof-of-Stake consensus mechanism, changing the fundamental parameter of how miners are selected and incentivized. This allows the system to maintain security while dramatically improving scalability and reducing energy consumption, as PoS requires significantly less computational power while still providing strong security guarantees through economic incentives.
Solution Approach 2:
The patent replaces the energy-intensive mechanical Proof-of-Work system with a more efficient Proof-of-Stake system. Instead of requiring miners to solve computational puzzles (mechanical process), the system selects miners based on their stake in the network (economic mechanism), achieving the same security goals with far lower resource consumption and higher scalability.
2Extent of automation
If current miner matches bid and ask orders in Filecoin, then storage allocation is automated, but Quality-of-Service enforcement and client control deteriorate
Solution Approach 1:
The patent implements a feedback mechanism where clients can specify Quality-of-Service requirements in their bid orders, and the system provides feedback on whether these requirements are met. The layered architecture includes components that monitor and enforce QoS parameters, allowing clients to control and verify the service quality while maintaining automated allocation through the auction mechanism.
3Quantity of substance
If storage miners replicate data to increase mining probability, then storage capacity is improved, but data exclusivity and incentive to share deteriorate
Solution Approach 1:
The patent implements dynamic incentives where storage miners can adjust their replication strategies based on market conditions and QoS requirements. The system dynamically balances the incentive to replicate data for mining purposes with the incentive to share data for retrieval rewards, allowing the network to adapt to changing demands while maintaining both storage capacity and sharing incentives.
4Reliability
If Sia hosts provide proof-of-burn to prevent Sybil attacks, then network security is improved, but system sustainability and inflation rate deteriorate
Solution Approach 1:
The patent replaces the expensive proof-of-burn mechanism (which permanently destroys 4% of revenue) with a more sustainable proof-of-stake approach. Instead of disposable resources being burned, the system uses reusable staked assets that provide security without permanent loss, dramatically reducing the inflation rate from 30% to more sustainable levels while maintaining network security.
Data Source
AI summary
A computer-implemented method reliably stores data in a blockchain-based distributed storage system. The method utilizes computer processes carried out by a host computing device, including receiving from a renter computing device a storage contract proposal, sending over the network, by the host computing device to the renter computing device and to the blockchain, an acceptance of the storage contract proposal, and receiving from the blockchain, confirmation that a storage contract between the host computing device and the renter computing device has been added to the blockchain. After the data have been stored, the processes include computing a checksum, sending it to the renter computing device and to the blockchain and receiving, from the blockchain, confirmation that the checksum has been added to the blockchain.
