Blockchain technology is transforming industries—from finance and supply chains to energy and digital identity. As adoption accelerates, the need for standardized frameworks becomes critical to ensure interoperability, security, and global scalability. Leading this charge is the IEEE Computer Society Blockchain and Distributed Ledger Standards Committee (IEEE C/BDL SC), established on September 5, 2019, to develop globally recognized standards that shape the future of decentralized systems.
This article explores the committee’s mission, published standards, active projects, and its pivotal role in advancing blockchain innovation through structured, consensus-driven governance.
What Is the IEEE Blockchain and Distributed Ledger Standards Committee?
The IEEE Computer Society Blockchain and Distributed Ledger Standards Committee oversees the development of technical standards for blockchain and distributed ledger technologies (DLT). Its scope spans data formats, system implementation protocols, application-specific use cases, and cross-industry integration models.
By establishing clear, vendor-neutral benchmarks, the committee enables developers, enterprises, and governments to build interoperable, secure, and scalable blockchain solutions. These standards are essential for fostering trust in digital ecosystems where transparency, immutability, and auditability are paramount.

Published IEEE Blockchain Standards
The committee has already released foundational standards that are shaping real-world blockchain deployments.
IEEE 2418.2-2020 – Data Format for Blockchain Systems
This standard defines core data structure requirements for blockchain systems, including:
- Data classification and correlation
- Element format, type, identifier, and length
- Consistent data modeling across platforms
With formal data formatting rules, organizations can ensure seamless data exchange between disparate blockchain networks—a crucial step toward interoperability.
Status: Active
Published: December 23, 2020
IEEE 2418.7-2021 – Blockchain in Supply Chain Finance
Focusing on financial workflows, this standard outlines a reference architecture for blockchain-powered supply chain finance (SCF), defining roles such as:
- Core enterprises
- Suppliers
- Banks
- Blockchain platform providers
It details processes like asset issuance, transfer, financing, clearing, settlement, and traceability—enabling greater liquidity and transparency in global supply chains.
Status: Active
Published: October 28, 2021
Standards Currently Under Ballot
Two key initiatives are under active review:
P3207 – Blockchain-Based Digital Asset Identification
This project establishes methods for uniquely identifying crypto assets across blockchains. It includes specifications for:
- Data structure and format
- Asset management operations
- Metadata tagging and verification protocols
A universal identification system reduces fraud risk and enhances regulatory compliance.
P3218 – Blockchain for Carbon Trading Applications
Designed to support environmental sustainability, this standard delivers a technical framework for carbon credit trading using blockchain. It covers:
- Carbon voucher coding
- Secure transaction interfaces
- Access controls and audit trails
This initiative supports transparent, tamper-proof carbon markets essential for achieving net-zero goals.
Active Blockchain Standards Projects (P3201–P3230)
The IEEE C/BDL SC is driving innovation through over two dozen active working groups. Key projects include:
Identity & Access Management
- P3201: Defines granular access control for nodes, smart contracts, users, and global functions.
- P3209: Specifies cryptographic key management across multiple blockchain systems.
- P3210: Establishes a framework for decentralized digital identities (DID), including credential issuance and authentication.
Interoperability & Cross-Chain Communication
- P3203: Introduces a naming protocol to locate trusted nodes across blockchains.
- P3204: Ensures consistency in cross-chain transactions without centralized intermediaries.
- P3205: Standardizes data authentication and communication between heterogeneous blockchains.
Digital Assets & NFTs
- P3206: Classifies blockchain-based digital assets (e.g., tokens, NFTs).
- P3208: Defines secure exchange models for digital assets.
- P3220: Provides guidance on converting physical assets into NFTs and managing their lifecycle.
Security & Governance
- P3212: Sets governance structures for both public and private blockchains.
- P3214: Outlines testing methodologies for functionality, performance, security, and compliance.
- P3219: Introduces a zero-trust security model for IoT devices using blockchain-based identity verification.
Industry-Specific Applications
- P3224: Enables blockchain-based green power certification.
- P3225: Evaluates low-carbon zones using blockchain-tracked emissions data.
- P3230: Supports demand-response systems in smart power grids using DLT.
These projects reflect a comprehensive approach to integrating blockchain into critical infrastructure while addressing privacy, scalability, and regulatory needs.

Why Blockchain Standardization Matters
Without standardization, blockchain ecosystems risk fragmentation—leading to siloed networks, incompatible protocols, and increased security vulnerabilities. The IEEE C/BDL SC addresses these challenges by:
- Promoting interoperability between different DLT platforms
- Enhancing security through unified testing and governance frameworks
- Supporting regulatory compliance with transparent data handling practices
- Accelerating adoption across sectors like finance, healthcare, logistics, and energy
Organizations leveraging IEEE-compliant solutions benefit from reduced integration costs, improved audit readiness, and greater stakeholder trust.
