Blockchain Transaction Visualizer

Visualize IoT Blockchain Transactions

Blockchain Consensus Visualizer

Try

Choose a consensus model and submit a sensor transaction to the pending block.

Observe

Compare confirmation delay, energy cost, and finality as the consensus choice changes.

Explain

Explain why consensus overhead and fault assumptions—not the word blockchain—determine suitability.

Legend. Blue nodes propose or validate work; green blocks are committed; amber transactions are pending; red marks rejected or invalid work.

Blockchain Consensus Visualizer -- Watch how IoT transactions are broadcast across a 7-node validator network, validated through different consensus mechanisms, and appended to a small ledger. Use the scenarios and comparison table to decide which consensus style fits a realistic IoT deployment.

Goal

Compare consensus speed, energy cost, and trust assumptions for IoT ledgers.

Try

Apply a scenario, submit a transaction, then compare all consensus methods.

Watch

Follow validator states, finality, confirmation time, energy cost, and chain growth.

Reflect

Why do private IoT networks often avoid high-energy public-chain consensus?

Guided Investigation

Start with Cold Chain Alert and submit the default PBFT transaction.
Use Compare Consensus to see why PoW is rarely a good fit for battery devices.
Switch to Gateway Access Audit and compare PBFT with Raft for trusted deployments.

Scenario Focus

Cold Chain Alert models a temperature reading that must be confirmed quickly by a private consortium.

PBFT Consensus

3-phase protocol: Pre-prepare, Prepare, Commit. Fast finality, ideal for private IoT networks.

What to Notice

Submit a transaction, then compare whether energy cost, finality, or decentralization matters most for this scenario.
