Reduced Costs: By removing intermediaries, blockchain lowers transaction fees.
Real-Time Settlements: Transactions are completed instantly, eliminating delays.
This shift to decentralized trading is particularly beneficial for smaller organizations that often struggle to access traditional carbon markets.
What are Blockchain-Based Carbon Registries?
A blockchain-based carbon registry is a digital platform that records and tracks carbon credits. Unlike traditional registries, which are often fragmented and opaque, blockchain-based systems offer a unified, transparent solution.
How It Works:
Each carbon credit is registered on the blockchain with unique metadata, including details like the project’s type, location, and verification status.
These records are accessible to all participants, ensuring that everyone has a clear view of the market.
Advantages of Blockchain Registries:
Transparency: All participants can verify the origins and authenticity of credits.
