In an era where digital trust is paramount, the need for secure, transparent, and efficient transaction systems has never been greater. The CN108399571A patent introduces a groundbreaking approach: a blockchain-based, trustless transaction method and system powered by smart contracts. This innovation eliminates the need for intermediaries or escrow services, enabling direct peer-to-peer (P2P) exchanges with cryptographic assurance.
By leveraging the immutability and decentralization of blockchain technology, this system ensures that transactions are executed only when predefined conditions are met—providing security for both parties without relying on third-party oversight.
How It Works: A Step-by-Step Breakdown
The core mechanism revolves around smart contract automation on a blockchain network. Here's how the process unfolds:
Smart Contract Creation
The transaction initiator (input party) drafts a smart contract containing essential details:- Transaction amount
- Public key for verification
- Optional: one or more recipients (output parties)
- Distribution rules (if multiple recipients are involved)
- Deployment to Blockchain
Once created, the smart contract is deployed onto the blockchain network. This makes it publicly verifiable and tamper-proof. - Recipient Confirmation
The recipient (output party) confirms participation by signing a message with their private key. Upon confirmation, the smart contract activates and locks (freezes) the transaction amount—ensuring funds are reserved but not yet released. - Off-Chain Transaction Execution
The actual exchange (e.g., delivery of goods, services, or data) occurs off-chain. This maintains efficiency while using the blockchain only for final settlement. Final Settlement or Cancellation
- ✅ If successful: The initiator signs a “transaction complete” message. The smart contract unfreezes the funds and automatically transfers them to the recipient(s) according to predefined rules.
- ❌ If failed or canceled: Both parties must sign a “cancel transaction” request. Only then is the contract terminated, and funds returned to the initiator.
This two-phase model—off-chain execution with on-chain settlement—ensures speed, privacy, and security.

Key Features and Technical Advantages
Multi-Party Support with Automated Distribution
Unlike basic P2P models, this system supports multiple recipients. During contract creation, the initiator can define distribution logic—for example, splitting payments among partners or subcontractors automatically upon completion.
Threshold-Based Participation Control
An advanced feature checks how many active contracts a recipient has already signed. If their count exceeds a preset threshold, they’re temporarily excluded from new transactions. This prevents overload and potential abuse, enhancing system reliability.
Mutual Consent for Cancellation
To cancel a transaction, all involved parties must agree and sign the cancellation request. This prevents unilateral reversals and protects against fraud or disputes.
Immutable and Transparent Recordkeeping
Every action—creation, confirmation, completion, or cancellation—is recorded on the blockchain. These records are:
- Tamper-proof
- Time-stamped
- Publicly auditable
Such transparency builds trust in decentralized environments where identity may be pseudonymous.
Core Keywords Driving Innovation
This system exemplifies advancements in several key areas:
- Blockchain
- Smart contracts
- Decentralized transactions
- Peer-to-peer (P2P) exchange
- Trustless systems
- Cryptographic security
- Off-chain execution
- Automated settlement
These terms reflect the evolving landscape of digital finance and secure data exchange, where automation and decentralization replace traditional gatekeepers.
Real-World Applications
While originally designed as a general-purpose transaction framework, this model applies across numerous industries:
E-Commerce and Digital Marketplaces
Buyers and sellers can trade without escrow services. Goods are shipped off-chain; payment releases only upon confirmation.
Freelance and Gig Economy Platforms
Clients lock funds in a smart contract before work begins. Freelancers get paid automatically once deliverables are approved.
Supply Chain Payments
Automate multi-party payouts—manufacturers, logistics providers, and distributors—all governed by a single contract.
Decentralized Finance (DeFi) Integrations
Use this logic for loan disbursements, insurance claims, or conditional asset transfers without centralized oversight.

Frequently Asked Questions (FAQ)
What makes this system "trustless"?
A "trustless" system doesn't require participants to trust each other—or any third party. Instead, trust is placed in code and cryptography. The smart contract enforces rules automatically: funds are locked until conditions are met, eliminating counterparty risk.
Can the transaction amount be changed after deployment?
No. Once the smart contract is published on the blockchain, its terms—including the transaction amount—are immutable. Any changes would require canceling the current contract and creating a new one.
Is this system compatible with existing blockchain networks?
Yes, the architecture is adaptable to various blockchain platforms that support smart contracts—such as Ethereum, Binance Smart Chain, or enterprise-grade blockchains like Hyperledger Fabric.
How does it handle disputes between parties?
The system assumes mutual agreement off-chain. If disputes arise, resolution must occur externally (e.g., mediation). The smart contract only acts on jointly signed instructions—it cannot interpret subjective disagreements.
What happens if one party refuses to sign the completion or cancellation?
Until both parties provide required signatures, the funds remain frozen. While this protects against unilateral actions, it also highlights the importance of clear communication and dispute-resolution protocols outside the system.
Does this method require cryptocurrency?
While designed with digital assets in mind, the framework can also manage fiat-based stablecoins or tokenized real-world assets. The underlying value unit depends on the blockchain implementation used.
Why This Matters for the Future of Digital Transactions
Traditional financial systems rely heavily on intermediaries—banks, payment processors, escrow agents—all adding cost and delay. This patent outlines a future where transactions are:
- Faster due to automation
- Cheaper due to disintermediation
- More secure due to cryptographic enforcement
As blockchain adoption grows, especially in DeFi and Web3 ecosystems, solutions like this become foundational infrastructure for global digital commerce.
Moreover, its design principles align with modern cybersecurity standards—using digital signatures, public-key cryptography, and decentralized consensus—to resist tampering and fraud.

Conclusion
The CN108399571A patent presents a robust model for conducting secure, intermediary-free transactions using blockchain and smart contracts. By combining automated execution with cryptographic verification and mutual consent mechanisms, it offers a scalable solution for trustless digital exchange.
Whether applied in e-commerce, freelancing, supply chains, or decentralized finance, this method represents a significant step toward a more transparent, efficient, and equitable digital economy.
As innovation continues to build upon these foundations, we move closer to a world where trust is not assumed—but mathematically guaranteed.
