ECO2 Ledger

The Emissions Trading Blockchain Powered by Carbon Neutrality

DPoS Consensus

Zero Emission

Blockchainization of Carbon Credits

Global Carbon Registry

Blockchain Carbon Account

Offset Pool


ECO2 Ledger's consensus mechanism is based on DPoS, uses a trusted delegate election system to elect 21 Emission Reduction Nodes, and uses a practical Byzantine Fault Tolerance algorithm (pBFT) to ensure the consistency and security of chain development.

  • 21 Emission Reduction Nodes (ER Nodes)

  • Election of ER Nodes are held every 30 days

  • New block is created every 10 seconds

  • 1 ECO2 Token = 1 Vote

Zero Emission

In order to maintain zero emissions of ECO2 Ledger, operations and blocks created by ER Nodes need to use carbon credits to offset the CO2 emissions generated by the blockchain network’s electricity consumption.

  • The ECC Token (ECO2 Carbon Credit) represents carbon credits on ECO2 Ledger

  • 1 ECC Token = 1 gram of a carbon credit

  • The issuance of ECC tokens on ECO2 Ledger = The amount of real-world carbon credits purchased from the international market

  • Block creation and on-chain operations of ECO2 Ledger will consume ECC tokens to remain carbon neutral

Blockchain-based Emission Trading

Using blockchain technology, ECO2 Ledger provides a more convenient, more transparent and faster method for carbon trading.

  • Decentralized carbon market

  • Joint participation of individuals and enterprises

  • Direct transactions on the blockchain

  • Transparent and open carbon accounts and on-chain carbon neutrality record

  • Diversified use of carbon credits within Dapps
