To simulate the Blockchain Networks Projects using OPNET and it also known as Riverbed Modeler which is not directly modelled for the Blockchain Network to replicate by the way of it deliberates to concentrate on long-established network protocols to network performance evaluation. But we could replicate the blockchain-like characteristics or else the network communications of appropriate to the blockchain using OPNET tool by executing the custom set up to creating the alternations to the existing structures.
The following are the brief procedures in which on how to replicate the blockchain network communications or the applications of OPNET:
Step-by-Step to use Simulate the Blockchain Networks projects using the OPNET:
- Set Up Nodes to Represent Blockchain Participants:
- Every node in OPNET replication to characterize the blockchain users such as miner, node, or client.
- To utilize OPNET’s Node Model Editor to state the node features which simulate the functions in a blockchain networks like a miners, validators, and ordinary nodes
- Define Blockchain Network Topology:
- To organize the nodes in a peer-to-peer (P2P) topology.
- Utilizing a mesh or partly to joins the topology to simulate the devolved environment the blockchain networks.
- To connect the nodes to build a network in which every node can interact directly or else indirectly to replicating the propagation of blocks and dealings of the network.
- Configure Data Transmission and Propagation Delays:
- To configure the data links with suitable bandwidth and delay to simulate the accurate network latency.
- To Blockchain networks has been particularly public ones and knowledge of the propagation latency that we could to replicate through configuration of the variable communication of latency among nodes.
- Create Transaction and Block Generation Models:
- To configure every node to create the packets of arbitrary intervals and illustrative the communications to developed through the consumers to replicate the exchange packets in OPNET.
- To replicate the blocks to set up a “block” as a several transactions containing the higher packet. To use the batch execution of configuration in OPNET to replicate this.
- Define Consensus Protocol Behaviour:
- To execute a tradition manual and process the patterns to replicate the consensus mechanism such as Proof of Work, Proof of Stake.
- For Proof of Work (PoW):
- To utilized the OPNET’s processing components to replicate the computational tasks like a mining.
- Nodes should create the “blocks” only than the amount of time to set the randomization to characterize the PoW difficulties level of the networks.
- For Proof of Stake (PoS):
- To state the leader selection method in which the nodes are choose to the generate the blocks according to the preset conditions and to replicating the staking and evaluation methods.
- Set Up Communication Protocols:
- To set up the nodes to trade off to communicate the block information of alike broadcasting.
- To utilized the multicast and broadcast protocols to replicate the block and communication propagation through the network.
- Describe the timeout conditions and retry mechanisms to expressive the network latency and confirmation times of blocks.
- Simulate Network Traffic and Data Analysis:
- To implement the simulation of traffic flows that illustrative the standard blockchain of traffic such as transactions and blocks.
- To observe the metrices such as transaction throughput, latency, and confirmation times.
- To use the packet arrival and service performance to estimate the delay that is important to calculating the performance of blockchain networks.
- Analyse Performance Metrics:
- To estimate and examine the parameters like block propagation time, transaction delay, and network congestion to analyse the network’s efficiency and scalability.
- To Utilized the OPNET’s outcomes to examine the characteristic to build the visual details and investigate the effect of network size, delay, and bandwidth performance of the blockchain.
Example Blockchain Project Ideas with OPNET
- Blockchain Transaction Propagation Delay Analysis: To estimate on how to high the number of nodes affects the confirmation time of communications with network latency.
- Consensus Mechanism Simulation: To validate the efficiency of PoW and PoS consensus mechanisms through altering the packet generation and validation processes.
- Scalability of Blockchain Network: To replicate the network sizes and estimate the impacts on parameter such as throughput and transaction delay.
- Attack Simulation such as DDoS on Blockchain Nodes): To configure the particular nodes to create maximum numbers of “transaction” traffic to examine the effect of DDoS attacks on confirmation times of communications.
In this manual we clarify the descriptive procedure to simulate and implement the Blockchain Networks Projects implemented in the tool of OPNET and also, we deliver the expressive of blockchain networks and set up of the configuration application of the networks and finally analyse the metrices of the blockchain network performance. If you need any doubts to regarding these projects, we will clarify the next manual.
