Cross-Border Payment/NFT Authentication/Supply Chain Traceability · GDPR Compliant · End-to-End Delivery

Blockchain Services are designed for businesses needing to solve data tampering risks, achieve process traceability, and comply with global regulations. Unlike generic blockchain products, we offer end-to-end services: needs analysis → chain selection → smart contract development → deployment & maintenance. Based on global blockchains (Ethereum, Hyperledger Fabric), we focus on cross-border payment settlement, NFT asset authentication, and supply chain traceability, strictly complying with GDPR and MiCA Regulation. Helping businesses reduce data tampering to 0, improve traceability efficiency by 80%, and cut compliance costs by 40%, it aligns with global policies and industry needs.

1. Needs Analysis & Chain Selection

• Business Pain Point Identification: Dive into business processes (cross-border trade, NFT creation) to spot links requiring "trusted data storage, transparent traceability" (e.g., "cross-border payment settlement", "NFT ownership authentication"), delivering a Blockchain Needs Analysis Report;
• Compliant Chain Selection: Recommend blockchains based on industry and regulations (e.g., Ethereum for NFTs, Hyperledger Fabric for enterprise supply chains), define on-chain data scope (e.g., "only store data hashes, not raw sensitive data") to meet GDPR/MiCA requirements;
• Solution Design: Create "on-chain + off-chain" collaboration plans (e.g., "core data on-chain, associated data off-chain encrypted") and clarify smart contract functions (e.g., "auto-execute cross-border payment terms"), forming an On-Chain Implementation Plan.

2. Smart Contract Development & Data On-Chaining

• Custom Smart Contract Development:
• Function Development: Develop contracts using Solidity/Rust (e.g., cross-border payment contracts, NFT minting contracts) to enable "auto on-chain certification, real-time traceability queries" (e.g., "NFT ownership can be verified globally after minting");
• Security Audit: Conduct code audits (detecting logic flaws, permission vulnerabilities) and stress tests to ensure no post-launch risks, avoiding "asset loss or data tampering from contract bugs";
• Compliant Data On-Chaining:
• Data Preprocessing: Anonymize sensitive data (e.g., customer payment info, personal IDs) to comply with GDPR, ensuring only non-sensitive data/hashes are on-chain;
• Multi-Source Integration: Connect with enterprise systems (e.g., cross-border ERP, NFT platforms) to enable "auto data sync to chain" (e.g., "cross-border trade orders trigger on-chain certification automatically").

3. Deployment, Maintenance & Iteration

• Multi-Environment Deployment:
• Private Deployment: Deploy dedicated blockchain nodes for financial/enterprise clients (e.g., "a multinational bank deploys Hyperledger nodes for internal payment settlement");
• Cloud Deployment: Integrate with global cloud blockchain services (AWS Managed Blockchain, Google Cloud Blockchain) to quickly build on-chain apps (e.g., "a fashion brand launches NFT authentication on Ethereum in 3 days");
• Long-Term Maintenance & Optimization:
• Node Monitoring: 24/7 monitor node status (connectivity, block generation speed) to ensure 99.9% service availability;
• Function Iteration: Update smart contracts per business changes (e.g., "expand cross-border contract functions for new markets") and deliver Blockchain Maintenance Reports to keep on-chain apps aligned with business needs.

4. Target Scenarios

• 1. Cross-Border Payment Settlement: E.g., "a US-EU trading company’s payment system" — built on Stellar, cross-border payments are settled in 3 seconds (vs. 3 days via traditional banks), transaction costs cut by 70%, and compliance with MiCA Regulation;
• 2. NFT Asset Authentication: E.g., "a luxury brand’s NFT authentication" — developed on Ethereum, luxury bags’ serial numbers are minted as NFTs, consumers verify authenticity via wallet, counterfeit rate drops to 0, brand trust improves by 60%;
• 3. Supply Chain Traceability: E.g., "a European food company’s ingredient traceability" — built on Hyperledger Fabric, wheat from farm to supermarket is tracked on-chain, food safety incidents are traced in 1 hour (vs. 7 days), recall costs reduced by 50%;
• 4. Legal Document Certification: E.g., "a global law firm’s contract certification" — built on Corda, legal contracts’ hashes are on-chain, cross-border contract disputes are resolved in 2 days (vs. 15 days), legal costs cut by 40%.
