GreenT Blockchain Technology
GreenT is built as a large-scale blockchain infrastructure designed for integration across various industries. It functions as a private enterprise ecosystem, composed of multi-party consortiums and joint venture frameworks. At its core lies the GreenT Payment System, which is developed on Hyperledger Fabric (HLF)—a permissioned blockchain platform selected for its high scalability, transaction throughput, and enterprise-grade architecture.
Beyond the foundational use of Fabric, GreenT has extended its blockchain layer through:
⚙️ Custom chaincodes for token issuance and smart contract automation
🔌 Dedicated APIs to support seamless integration with diverse business systems
🧠 Why Hyperledger Fabric (HLF)?
Hyperledger Fabric is a permissioned blockchain framework that allows only verified participants to join the network. This design eliminates the need for traditional, resource-intensive consensus mechanisms like proof-of-work, thereby improving efficiency, scalability, and security.
Key Features:
🔐 Permissioned Access Only authenticated entities can access or operate within the network
📦 Channel Architecture The network is divided into private channels, each supporting custom configurations and privacy levels
Participants can join single or multiple channels based on their business needs
Ledgers can be either shared or isolated per use case
⚡ High Performance & Parallel Processing Transactions are processed in parallel, enabling throughput of tens of thousands of transactions per second
⏱️ Real-Time Transaction Finality Transactions are validated and blocks are created immediately upon initiation, enabling true real-time settlement capabilities
🏗️ Tailored for Enterprise-Grade Applications
GreenT leverages the flexibility of HLF to construct customized payment environments that meet both:
🔧 Business-specific operational requirements
🌐 Interoperability across digital services and physical commerce infrastructure
Combined with GreenT’s bespoke chaincodes and API layer, the network is optimized for:
Tokenized transaction processing
Integration with wallets, POS systems, and e-commerce platforms
Scalable expansion across retail, content, and environmental sectors
GreenT’s blockchain infrastructure ensures real-time payments, security, scalability, and privacy—making it an ideal foundation for next-generation Web3 commerce and financial applications.
🔐 Transaction and Security
GreenT adopts the transaction processing structure of Hyperledger Fabric (HLF) to ensure secure and verifiable execution.
The process follows three core steps:
🟢 Step 1 – Transaction Proposal
The client application generates a transaction proposal via the integrated SDK.
🧠 Step 2 – Endorsement Execution
Designated endorsing peers, defined by the endorsement policy, simulate and execute the transaction using the relevant chaincode.
📩 Step 3 – Response Delivery
Each peer returns the simulated execution results to the client application, including read/write sets and digital signatures.
✅ Step 4 – Policy Validation
Once all required endorsements are collected, the validated transaction is sent to the ordering service.
🧱 Step 5 – Block Generation
The ordering service assembles transactions into blocks in arrival order and distributes them to all peers in the respective channel.
🔍 Step 6 – Block Validation
Each peer checks whether:
The block satisfies the endorsement policy
The ledger state has not changed due to conflicting transactions
🔗 Step 7 – Ledger Commitment
Valid blocks are appended to the chain, and the ledger state is updated accordingly.
🔄 Distributed Trust & Transparency
Through this decentralized and policy-driven structure:
All approved participants who meet endorsement criteria can execute transactions on the GreenT blockchain
Smart contract UIs provided to ecosystem partners allow real-time verification of transaction history among parties
This framework enables GreenT partners to:
Easily integrate blockchain functions into existing business operations
Develop new services on top of the GreenT platform without requiring deep technical knowledge
GreenT's architecture offers a foundation for secure payments, transparent verification, and scalable business innovation powered by blockchain.
