## Abstract

A blockchain-based system and method for verifying Certificates of Authentication (COAs) in supply chain management is disclosed, adhering to ASTM D8558-24 guidelines and relevant ISO standards including ISO/IEC 27001, ISO 28000, and ISO 9001. The system utilizes a custom Layer 1 (L1) blockchain built on the Avalanche platform, implementing a dual-token model to create, manage, and verify COAs as Non-Fungible Tokens (NFTs). It features AI-powered authentication, enhanced security measures, and a data marketplace for monetizing authenticated supply chain data. The system offers improved scalability, customization for various industries, and facilitates both B2B and B2C transactions. With cross-chain communication capabilities and integration with existing supply chain systems, the invention addresses environmental and social considerations while providing comprehensive interoperability. This solution aims to revolutionize supply chain authentication, offering enhanced transparency, efficiency, and trust in global trade, all while maintaining compliance with international standards for security, quality, and supply chain management.

## Claims

### Claim 1

A blockchain-based system for verifying Certificates of Authentication (COAs) in supply chain management, compliant with ASTM D8558-24 and relevant ISO standards, comprising:
a custom Layer 1 (L1) blockchain platform built on Avalanche;
a dual-token model featuring a utility token (BTIC) and a stablecoin (BCOA);
a tool for minting COAs as Non-Fungible Tokens (NFTs);
an AI-powered verification system for authenticating COAs; and
integration capabilities with various tracking devices and existing supply chain systems.

### Claim 2 (depends on 1)

The system of claim 1, wherein the COA minting process includes assigning unique identifiers, metadata, and digital signatures, with minting fees paid in BCOA tokens, in accordance with ASTM D8558-24 guidelines.

### Claim 3 (depends on 1)

The system of claim 1, wherein the authentication process includes AI-powered preliminary analysis, examining smart contracts, verifying metadata, confirming digital signatures, and checking transaction history, adhering to ISO/IEC 27001 information security standards.

### Claim 4 (depends on 1)

The system of claim 1, further comprising customizable privacy settings, enhanced regulatory compliance features, and industry-specific optimizations, in line with ISO 28000 supply chain security management standards.

### Claim 5 (depends on 1)

The system of claim 1, further comprising support for B2B and B2C transactions in supply chain management, including inbound and outbound transfer capabilities, compliant with ISO 9001 quality management standards.

### Claim 6 (depends on 1)

The system of claim 1, wherein the implementation adheres to ISO 22301 business continuity management standards to ensure resilience in supply chain operations.
