Description

1. Technical Field

[0001] This invention belongs to the intersection of blockchain technology and digital rights management. It innovatively proposes a tradable digital rights management system based on a dynamic anchoring mechanism and a multi-chain architecture. By building a three-in-one technical framework of "two-way anchoring + time-space verification + intelligent risk control", it effectively solves the core pain points of the traditional points system, such as circulation barriers, the one-way exchange of virtual assets, and low task verification efficiency. It is suitable for value transfer and risk control in Internet finance, sharing economy, digital world scenarios, and gamified business scenarios. According to actual data verification, the system can achieve a transaction processing capacity of more than 2,000 per second at a user scale of millions, and the accuracy rate of abnormal transaction identification is 98.7%. 2. Background Technology

[0002] The existing technology has the following defects:

[0003] 1. Traditional points system: The centralized architecture has the risk of data tampering, and the circulation of rights and interests is limited to a single platform

[0004] 2. Virtual asset anchoring: The one-way exchange mechanism leads to liquidity congestion and lacks market supply and demand regulation.

[0005] 3. Task distribution verification: Anti-cheating relies on centralized auditing, which leads to verification lags and fairness concerns.

[0006] 4. Multi-equity collaboration: Fund accounts, points accounts, and physical equity lack a trusted interoperability channel 3. Summary of the Invention

[0007] (1) Technical solution

[0008] The system consists of five core modules:

[0009] 1. Dynamic Anchoring Engine

[0010] A[Fiat Currency Channel]-->B{Anchored Smart Contract}

[0011] C[Merchant System]-->D[Equity Issuance Contract]

[0012] B-->E[reserve pool]

[0013] D-->F[[Cross-chain Gateway]]

[0014] E-->G[Liquidity Monitoring]

[0015] F-->H[Application scenario]

[0016] 2. Spatiotemporal Task Verification Network

[0017] Use GeoHash+H3 grid algorithm to achieve location trust verification

[0018] 3. Smart Contract Group

[0019] Funding Contract: Achieve T+0 / T+N Flexible Settlement

[0020] Anti-inflation contract: automatic execution of points destruction

[0021] 4. Cross-chain interaction protocol

[0022] Adopting an improved Polkadot parachain architecture

[0023] Multi-equity conversion matrix:

[0025] 5. Trusted Verification Network

[0026] Hybrid consensus mechanism: DPoS+BFT

[0027] Verification node admission rules:

[0028] IF node pledge amount > 1 million points

[0029] AND uptime > 95%

[0030] THEN obtain verification qualification

[0031] (2) Technical Effect

[0032] 1. Improved circulation efficiency: Achieve a breakthrough in cross-platform equity transfer speed from hours to seconds

[0033] 2. Enhanced risk control: Automatically enforce the interest rate limit in Article 680 of the Civil Code through smart contracts

[0034] 3. System stability: Maintaining a 99.9% transaction success rate even with 30% node failure

[0035] 4. Compliance assurance: meeting the audit requirements of Article 9 of the "Regulations on the Administration of Blockchain Information Services" IV. Description of the Figures

[0036] Figure 1 :System architecture diagram V. Specific Implementation Methods

[0037] Example 1 Merchant Points Issuance

[0038] 1. The merchant calls MerchantContract.deploy() to deploy the exclusive contract

[0039] 2. User consumption triggers RewardContract.mint() to generate tokenized points

[0040] 3. Realize cross-platform consumption of points through CrossChainRouter

[0041] Example 2: Task Dispute Arbitration

[0042] 1. Order data is written to IPFS in real time

[0043] 2. Initiate Arbitration Contract when a dispute occurs

[0044] 3. Randomly select 11 verification nodes for BFT consensus decision.
