Detailed Comparison

Layer Architecture and Scalability

Ethereum Classic (ETC) and Arbitrum represent different approaches to blockchain architecture. ETC operates as a Layer 1 blockchain, serving as a base layer protocol, while Arbitrum functions as a Layer 2 scaling solution built on top of Ethereum.

The scalability difference is significant:

• Ethereum Classic: 15 TPS (transactions per second)
• Arbitrum: 4,000 TPS

This dramatic difference in transaction throughput demonstrates Arbitrum's superior scaling capabilities. Users on Arbitrum can expect much faster transaction processing and less network congestion. The 266x improvement in TPS makes Arbitrum more suitable for high-volume applications like DeFi protocols or gaming platforms.

Consensus Mechanisms

The chains employ different consensus mechanisms:

• Ethereum Classic: Proof of Work (PoW)
• Arbitrum: Proof of Stake (PoS)

ETC's PoW consensus requires significant computational power and energy consumption for mining operations. This makes it more decentralized but less environmentally friendly. Arbitrum's PoS mechanism is more energy-efficient and allows for faster transaction finality, though it relies on the security of Ethereum's base layer.

Transaction Costs

Transaction fees show a notable difference:

• Ethereum Classic: 0.0001 ETH average
• Arbitrum: 0.101 ETH average

ETC offers significantly lower transaction fees, making it more accessible for smaller transactions and everyday users. Arbitrum's higher fees reflect the additional complexity of Layer 2 operations, though these fees are still generally lower than Ethereum mainnet during high congestion periods.

Technical Infrastructure

Both chains share some technical similarities:

• Block Time: 13 seconds for both chains
• Hashing Algorithm: Both use KECCAK-256
• Smart Contracts: Both support smart contract functionality
• EVM Compatibility: Both are EVM-compatible

This technical alignment makes both chains accessible to Ethereum developers and allows for easy porting of existing Ethereum applications. Developers can use familiar tools and languages like Solidity on both platforms.

Origins and Development

The chains have different origin stories:

• Ethereum Classic: Created by Vitalik Buterin, emerged from the original Ethereum blockchain following the DAO hack
• Arbitrum: Created by Germans Gedgauds, developed specifically as a scaling solution

ETC maintains historical significance as the original Ethereum chain, while Arbitrum represents modern innovation in blockchain scaling technology. This difference reflects in their approach to development and community governance.

Supply Economics

Both chains have interesting supply dynamics:

• Both feature unlimited maximum supply
• ETC maintains the original Ethereum monetary policy
• Arbitrum uses ETH as its native token, inheriting Ethereum's economic model

The unlimited supply model allows both chains to maintain long-term sustainability through transaction fees and block rewards, though their specific implementation differs due to their distinct consensus mechanisms.

Developer Ecosystem

Both chains maintain active development communities:

• Ethereum Classic: Has a more established ecosystem with historical roots
• Arbitrum: Features a growing ecosystem focused on scaling solutions

The development focus differs significantly:

• ETC developers often focus on maintaining and improving core protocol features
• Arbitrum developers concentrate on optimizing Layer 2 scaling and improving interaction with Ethereum mainnet

Use Cases and Applications

The chains serve different primary purposes:

• Ethereum Classic:
  • Traditional smart contract platform
  • Store of value
  • Decentralized applications
• Arbitrum:
  • High-throughput applications
  • DeFi protocols
  • Gaming platforms
  • NFT marketplaces

The higher TPS of Arbitrum makes it more suitable for applications requiring frequent transactions, while ETC's lower fees and established history make it attractive for value storage and simpler smart contract applications.

Network Security

Security approaches differ based on their architecture:

• Ethereum Classic: Relies on direct PoW security
• Arbitrum: Inherits security from Ethereum mainnet while adding its own security layer

ETC's security model is more traditional and battle-tested, while Arbitrum's security combines Ethereum's base layer security with additional Layer 2 protective measures. This creates different risk profiles for users and developers to consider when choosing a platform.
