Delegated Proof of Stake (DPoS) Consensus Mechanism

Nordek uses a Delegated Proof of Stake (DPoS) consensus mechanism to achieve network consensus. In DPoS, token holders elect a set number of delegates, known as validators, who are responsible for validating transactions and producing new blocks.

This election process is designed to be democratic, with voting power typically proportional to the number of tokens held by each participant. The selected validators take turns in proposing and validating blocks, ensuring a more predictable and efficient block production process compared to traditional Proof of Work (PoW) systems.

Network Topology and Node Structure

The Nordek network has various types of nodes, each serving specific functions. Validator Nodes are elected by token holders to validate transactions and produce new blocks; they help in maintaining the integrity and security of the blockchain. Full nodes store the entire blockchain ledger and participate in the network by relaying transactions and blocks, ensuring that the network remains decentralized and that data is consistently available. Light nodes do not store the full blockchain, relying instead on full nodes to provide necessary data, which are typically used in environments with limited resources, such as mobile devices.

The network operates on a peer-to-peer (P2P) topology, where nodes communicate directly with each other without a central authority. This structure enhances the network’s resilience and decentralization.

In the Nordek blockchain, block creation and validation follow a structured process:

1. Transaction Broadcasting: Users initiate transactions, which are broadcast on the network. These transactions are collected into a pool of pending transactions.
2. Block Proposal: The elected validator for the current round selects transactions from the pool and proposes a new block.
3. Block Validation: Other validators verify the proposed block to ensure it adheres to the network’s rules and that all transactions are valid.
4. Block Addition: Once a majority of validators approve the block, it is added to the blockchain, and the transactions it contains are considered confirmed.
   The Nordek blockchain is designed for high transaction throughput. It achieves an average block interval of approximately 5 seconds, allowing for rapid confirmation of transactions. The network can process around 120 native token transfers and 60 TL20 token transfers per second. The faster processing of native token transfers is due to the absence of computations running on the network’s virtual machine.

Highlights

• Nordek utilizes a Delegated Proof of Stake (DPoS) consensus mechanism, where token holders elect validators to manage block production and transaction validation.
• The network comprises validator nodes, full nodes, and light nodes, operating on a peer-to-peer topology to maintain decentralization and resilience.
• Block creation involves transaction broadcasting, block proposal by validators, validation by other validators, and block addition upon approval.
• The network achieves an average block interval of approximately 5 seconds and can process around 120 native token transfers and 60 TL20 token transfers per second.
