Overview of Ethereum and Avalanche
Ethereum, launched in 2015 by Vitalik Buterin, revolutionised blockchain with smart contracts, enabling decentralised applications (dApps), DeFi, and NFTs. With more than a million transactions every day and a sizable developer community, it is the biggest smart contract platform. Since 2022, Ethereum’s native token, ETH, has powered staking and transactions via Proof-of-Stake. It is the preferred choice for Web3 innovation because of its strong environment, despite its expensive fees.
Avalanche, launched in 2020 by Ava Labs, is a high-performance blockchain designed for speed and scalability. Up to 6,500 TPS with sub-second finality are supported by its distinctive Avalanche Consensus and three-chain architecture (X-Chain, C-Chain, and P-Chain). Its native coin, AVAX, powers staking and transactions. Ethereum’s hegemony is being challenged by Avalanche, which is becoming more popular in DeFi, gaming, and custom subnets and is compatible with Ethereum’s tools.
Pros of Ethereum
Ethereum has a strong foundation of innovation and adoption, which has contributed to its supremacy in the blockchain field. Here’s why it’s still a major force in 2025.
- First-Mover Advantage: Ethereum has a ten-year advantage because it was the first blockchain to implement smart contracts. With platforms like Uniswap, Aave, and OpenSea flourishing on its network, its pioneering role has solidified it as the basis for the majority of DeFi tokens & protocols, NFT marketplaces, and dApps.
- Huge Developer Community: With thousands of programmers creating on its platform, Ethereum has the biggest developer ecosystem in the cryptocurrency space. Industry standards such as Solidity and the Ethereum Virtual Machine (EVM) guarantee a constant flow of new initiatives and creativity.
- Strong DeFi Ecosystem: With more than $100 billion in total value locked (TVL) as of 2025, Ethereum has the most advanced DeFi ecosystem. Competitors cannot match the loan, borrowing, and yield farming opportunities provided by well-known protocols like Compound, MakerDAO, and Curve.
- NFT Dominance: With collections like CryptoPunks and Bored Ape Yacht Club, Ethereum is the market leader in NFTs. It is the go-to option for producers and collectors due to its large trading volume and connectivity with markets like OpenSea NFT.
- Better Scalability with Layer 2: Ethereum has used Layer 2 solutions like Arbitrum and Optimism since its 2022 PoS shift, which decreased costs and increased transaction speeds. These rollups increase Ethereum’s competitiveness by handling thousands of TPS while preserving its security.
- Decentralisation and Security: Ethereum’s Proof of Stake (PoS) network is extremely decentralised and safe, with more than 400,000 validators worldwide. Resilience against attacks is guaranteed by its extensive history and stringent upgrades, such as the Pectra upgrade in 2025.
- Global Adoption: With a market value of almost $190 billion, Ethereum’s ETH is the second-largest cryptocurrency and is traded on all the main exchanges. It is a reliable asset for institutions and investors due to its broad recognition and liquidity.
Cons of Ethereum
Ethereum isn’t flawless despite its advantages, and its shortcomings have allowed rivals like Avalanche to gain ground. Listed below are some of the areas where it fails.
- Exorbitant Transaction Fees: Ethereum’s Layer 1 gas fees, which frequently range from $1 to $5 per transaction amid network congestion, are still exorbitant even with Layer 2 solutions. For microtransactions or dApps that are cost-sensitive, this reduces its viability.
- Scalability Issues: Ethereum’s Layer 1 only handles 15–30 TPS, which is significantly less than rivals like Avalanche. Although rollups and sharding are increasing scalability, complete implementation is still under progress and is trailing behind more recent blockchains.
- Slower Transaction Finality: Ethereum transactions take about 12 seconds to complete, which irritates users used to Avalanche and other systems that provide almost instantaneous confirmations. Games and other real-time applications are impacted by this delay.
- Network Congestion: Network congestion, spiking fees, and delayed transactions are caused by high demand for Ethereum’s network, particularly during NFT decreases or DeFi booms. Despite improvements, this is still a problem.
- Complex improvements: The technological complexity of Ethereum’s PoS transition and continuing improvements (such as sharding) increases the possibility of delays or problems. Despite its potential, the 2025 Pectra update has drawn criticism for its expansive reach.
- Energy Perception: Ethereum’s early Proof-of-Work phase left a persistent impression of environmental harm, which some competitors make use of in their marketing, even though PoS reduced its energy consumption by 99.9%.
Pros of Avalanche
With technical benefits that appeal to both developers and users, Avalanche has become a fierce competitor to Ethereum. What makes it stand out in 2025 is as follows.
- Lightning-Quick Transactions: Avalanche outperforms Ethereum’s Layer 1 by orders of magnitude, processing 4,500–6,500 TPS with sub-second finality (<1 second). This speed is perfect for high-frequency trading, DeFi, and gaming.
- Low Transaction Fees: Avalanche is much more affordable than Ethereum, with an average transaction fee of $0.08, which makes it suitable for microtransactions and applications that are sensitive to costs. In emerging nations, adoption is fueled by this affordability.
- Scalable Architecture: Tasks are distributed for best performance by Avalanche’s three-chain structure, which consists of X-Chain (asset trading), C-Chain (smart contracts), and P-Chain (staking/subnets). The blockchain trilemma of decentralisation, security, and scalability is resolved by this approach.
- Custom Subnets: Suitable for commercial use cases such as supply chains or private finance networks, Avalanche’s subnets enable developers to construct customised blockchains with particular regulations. Subnets work in unison with the primary network.
- EVM Compatibility: Solidity and Ethereum’s EVM are supported by Avalanche’s C-Chain, allowing developers to port Ethereum dApps with little modification. This compatibility provides improved performance and access to Ethereum’s large developer community.
- Growing DeFi Ecosystem: With protocols like Trader Joe, Benqi, and Aave generating $11 billion in TVL, Avalanche’s DeFi environment is growing. Projects priced out of Ethereum are drawn to it because of its speed and low fees.
- Eco-Friendly Design: Avalanche’s low energy consumption, which was built on PoS from the beginning, satisfies the growing demand for sustainable blockchains. Efficiency is increased without sacrificing security thanks to its Snowman Consensus.
- Enterprise Adoption: Collaborations such as with New Jersey for property records and Deloitte for disaster relief highlight Avalanche’s practical applications, increasing its legitimacy outside of the cryptocurrency space.
Cons of Avalanche
Avalanche’s youthfulness and aspirations are accompanied by growing pains and imperfections. Below are the areas where it falters.
- Less Mature Ecosystem: Avalanche’s ecosystem, which was introduced in 2020, is less developed than Ethereum’s. It has fewer dApps, a lower TVL (around $11 billion compared to $100 billion for Ethereum), and less developer engagement. It’s still catching up in the marketspace compared to Ethereum.
- Reduced Adoption: Due to its lower user base, Avalanche handles about 150,000 transactions every day, while Ethereum handles one million. The supremacy of Ethereum is outpaced by its DeFi and NFT wallets & marketplaces.
- Complex Structure: New users and developers may become confused by the subnets and the three-chain structure (X-, C-, and P-Chains). Compared to Ethereum’s more straightforward structure, this intricacy might make onboarding more difficult.
- Security Issues: Although Avalanche’s consensus is safe, it hasn’t been put to the test as thoroughly as Ethereum’s. Although there haven’t been any significant breaches, there are theoretical hazards associated with its reliance on fewer nodes for transaction validation.
- Token Concentration: About 42% of AVAX tokens are held by insiders (team and venture capitalists), which could cause price volatility if they sell. The wider availability of Ethereum allays this worry.
- Restricted Exchange Availability: AVAX is listed on fewer major exchanges than ETH. For certain investors, this lowers accessibility and liquidity.
- Dependency on Subnets: Subnets are essential to Avalanche’s scalability, while their use is still in its infancy. Avalanche’s value proposition deteriorates if subnets don’t take off.
