The underlying logic of QKFile (Quark Distributed File System) is essentially a distributed storage network built on the Quark Blockchain (QuarkBlockChain).
Based on the information I have gathered, the underlying logic of QKFile can be summarized as: "Distributed File System + Blockchain Incentive Layer + Verifiable Market." It aims to solve the issues of decentralization, security, and efficiency in data storage through technological means.
Here is a detailed breakdown of its underlying logic:
1. Core Architecture: Distributed File System (Variant/Reference of IPFS)#
The infrastructure of QKFile draws from concepts similar to IPFS, with the core change being from "location-based addressing" to "content-based addressing."
Content Addressing:
The traditional HTTP protocol locates files on a server through "domain name + path" (location-based).
In QKFile, when you upload a file, the system generates a unique hash value (Hash) for that file using an encryption algorithm (hash function), which serves as the file's "ID number."
Logic: Any change of a single bit in the file content will result in a completely different hash value; conversely, identical files will have the same hash value. This ensures the uniqueness and immutability of the file.
Deduplication and Distribution:
The system automatically identifies duplicate files and stores only one copy, saving space.
Files are split into countless fragments (Sharding) and distributed across hard drives in different nodes worldwide, rather than being concentrated in a single data center.
2. Security and Consensus: Coupling with Quark Blockchain#
QKFile does not exist in isolation; it deeply relies on the Quark Blockchain (QuarkBlockChain) as its underlying infrastructure to ensure the reliability of storage and the integrity of data.
Hash Value on Chain:
Files themselves are stored in a distributed manner, but the hash values and transaction records of the files are recorded on the Quark Blockchain.
Logic: The blockchain has the characteristics of immutability and traceability. Once the hash value is on the chain, it is equivalent to stamping the file with a "timestamp" and "fingerprint," proving that the file existed at a certain point in time and has not been modified.
New Storage Proof (PoS/Proof of Storage):
The information mentions that QKFile combines the characteristics of the Quark Blockchain to design a specific storage proof mechanism.
Logic: Miners (storage providers) need to periodically prove to the network that they are indeed continuously storing data (not just claiming to store it). The system will reduce the mining difficulty based on the storage proof provided by the miners, thus rewarding them with tokens. This ensures that miners do not cheat (e.g., by deleting files).
3. Economic Model: Token Incentives and Verifiable Market#
This is the "blood system" that allows QKFile to operate. It turns storage space into a commodity, allocated through market mechanisms.
Dual Market Mechanism:
Storage Market: Users publish storage needs (orders), and miners compete to provide hard drive space.
Retrieval Market: When users need to download data, retrieval miners are responsible for quickly finding data fragments and assembling them for return.
Token Incentives (QKF):
Logic: Users need to pay QKF tokens to purchase storage and retrieval services.
Miners earn QKF by providing idle hard drive space (storage miners) and bandwidth (retrieval miners).
Smart Contracts Automatically Execute Transactions: Payments are executed only when services are correctly provided (data is fully stored or successfully retrieved).
4. Data Privacy and Encryption#
In distributed storage, preventing "neighbors" from snooping on your files is a key issue.
End-to-End Encryption:
Logic: Files are encrypted locally by the user before uploading (e.g., using the recipient's public key for encryption).
What is stored on the nodes are only encrypted "garbled" fragments. Even if the node owner wants to look, they cannot decrypt the content without the private key.
Authorized Access:
Only those with a specific hash address and decryption key can retrieve and piece together the complete file from the network.
Summary: QKFile Three-Layer Architecture Logic#
To help you understand more clearly, I have organized its underlying logic into the following three-layer structure:
Level Name Core Function Key Logic
Application Layer Verifiable Market Resource Trading Users pay for access, miners provide services to earn tokens (QKF).
Protocol Layer Distributed File System Data Management Content addressing (hash), file slicing, deduplication, version control.
Underlying Layer Quark Blockchain Security and Rights Recording hash fingerprints, verifying storage proofs, preventing data tampering.
One-Sentence Summary:
The underlying logic of QKFile utilizes the Quark Blockchain as a trust anchor, employs content addressing technology to fragment and encrypt files stored across global nodes, and leverages token economics (QKF) to incentivize miners to work honestly, ultimately building a next-generation internet storage protocol that is safer, more efficient, and less prone to data loss than traditional HTTP.
