Consensus Algorithms

Consensus algorithms are critical in ensuring the integrity and security of blockchain networks. Different platforms employ various algorithms, each with distinct trade-offs.

• Proof of Work (PoW): Used by Bitcoin and Ethereum (before Ethereum 2.0), PoW is energy-intensive but provides high security. It requires miners to solve complex mathematical puzzles to validate transactions.

• Proof of Stake (PoS): Ethereum 2.0 and other platforms like Cardano use PoS, which is more energy-efficient than PoW. Validators are chosen based on the number of tokens they hold and are willing to “stake” as collateral.

• Practical Byzantine Fault Tolerance (PBFT): Used by Hyperledger Fabric, PBFT is suitable for permissioned networks where participants are known and trusted. It offers high throughput and low latency.

• Raft: Corda employs a variation of the Raft consensus algorithm, which is efficient for private networks and ensures rapid transaction finality.

Transaction Throughput and Scalability

Transaction throughput is a critical factor in evaluating blockchain platforms, especially for applications requiring high-speed processing.

• Ethereum: Originally limited by its PoW consensus, Ethereum’s throughput is improving with Ethereum 2.0 and Layer 2 solutions like Optimistic Rollups.

• Hyperledger Fabric: Offers high throughput by allowing parallel execution of transactions and supports complex workflows through its modular architecture.

• Corda: Optimized for financial transactions, Corda provides high throughput and low latency, making it suitable for real-time applications.

Governance Models

Governance models dictate how decisions are made within a blockchain network, impacting its evolution and adaptability.

• Ethereum: Operates on a decentralized governance model, relying on community consensus for protocol upgrades and changes.
