Avalanche, Terra, and Cardano Are Challenging Ethereum’s Dominance

·

The blockchain landscape is evolving rapidly, with emerging Layer 1 protocols like Avalanche, Terra, and Cardano gaining momentum and steadily eroding Ethereum’s long-standing dominance. While Ethereum remains the cornerstone of decentralized finance (DeFi) and non-fungible tokens (NFTs), its persistent issues with high transaction fees and network congestion have created an opening for competitive networks to attract developers, users, and capital.

As the demand for scalable, secure, and cost-effective blockchain infrastructure grows, these next-generation platforms are stepping in with innovative solutions that prioritize speed, affordability, and usability—three critical factors for mainstream adoption.


Why Ethereum’s High Costs Are Driving Users Away

Ethereum has long been the go-to platform for smart contracts and decentralized applications (dApps). However, as DeFi and NFTs surged in popularity, the network became increasingly congested. This led to soaring gas fees, sometimes exceeding $50 per transaction during peak usage.

Despite the much-hyped London hard fork—which introduced EIP-1559 and a fee-burning mechanism—average transaction costs have not decreased meaningfully. In fact, they’ve risen in many cases, making small transactions economically unviable for average users.

This scalability bottleneck has pushed developers and investors to explore alternative Layer 1 blockchains that offer faster finality, lower costs, and improved user experiences—without sacrificing security or decentralization.

👉 Discover how next-gen blockchains are solving Ethereum’s biggest pain points.


Avalanche: Speed, Scalability, and a Thriving DeFi Ecosystem

Avalanche has emerged as one of the most promising Ethereum competitors, thanks to its unique consensus mechanism and sub-second finality. The network can process over 4,500 transactions per second (TPS), far outpacing Ethereum’s current capacity.

The launch of the Avalanche Bridge (AB) on July 29 was a game-changer. By enabling seamless asset transfers between Ethereum and Avalanche, AB lowered the barrier to entry for users seeking cheaper alternatives. Within weeks, the bridge facilitated over $1 billion in cross-chain transfers, signaling strong market demand.

Stablecoins like USDC are now fully supported, enhancing liquidity and usability across the ecosystem.

To accelerate DeFi growth, Avalanche launched the Avalanche Rush initiative—a $180 million liquidity mining program in partnership with top-tier protocols such as Aave, Curve, and SushiSwap. These integrations brought familiar tools to Avalanche while rewarding early adopters with AVAX incentives.

The results speak for themselves:

With robust infrastructure and growing community support, Avalanche is positioning itself as a serious contender in the Layer 1 race.


Terra: Building a Stablecoin-Powered Financial Ecosystem

Terra takes a fundamentally different approach by focusing on price-stable digital currencies. Its flagship stablecoin, TerraUSD (UST), is algorithmically pegged to the US dollar and used across various payment and savings applications.

Unlike traditional collateralized stablecoins, UST maintains its peg through a dual-token mechanism involving LUNA, the network’s volatile reserve asset. When UST deviates from $1, arbitrage opportunities allow users to mint or burn LUNA, stabilizing supply and demand.

This elegant design fueled explosive growth. Between July 20 and August 24, LUNA surged 530%, driven by increased adoption and confidence in the protocol’s economic model.

On August 25, the Terra community overwhelmingly approved the migration to Columbus-5, a major network upgrade that eliminated reliance on centralized oracles and improved overall security and efficiency.

“The on-chain proposal to migrate the Terra network to Columbus-5 has officially passed, with 99.99% voting in favor.”

One of Terra’s most successful applications is Anchor Protocol, a savings platform offering stable yields on UST deposits—historically around 20% APY during peak growth. To further boost liquidity, Anchor integrated ETH as a collateral asset for borrowing UST, attracting Ethereum-based users into the Terra ecosystem.

As a result, Terra’s TVL skyrocketed past $6 billion, making it the third-largest blockchain by total value locked, trailing only Ethereum and Binance Smart Chain.

Cardano: The Anticipated Rise of Smart Contracts

Cardano has built a reputation for academic rigor and methodical development. Unlike many other blockchains that launched smart contract functionality early, Cardano prioritized security and peer-reviewed research—delaying features until they met strict standards.

That patience may soon pay off. After years of anticipation, Cardano finally rolled out smart contract support in 2021, triggering a 190% surge in ADA’s price over just three weeks. Investors are excited about the potential for DeFi and NFTs to flourish on a highly secure, energy-efficient proof-of-stake network.

Even before full smart contract capabilities went live, Cardano introduced native tokens—a feature allowing users to create custom assets and NFTs without writing complex smart contracts. This simplified the process for artists and developers, leading to early experimentation in digital collectibles.

“Discover native tokens:

  • What they are
  • How to mint them
  • Methods for creating NFTs
  • Why you don’t need smart contracts”
    — Cardano Foundation (@CardanoStiftung), July 22, 2021

Additionally, Cardano boasts one of the highest staking participation rates in the industry. According to PoolTool, 70.98% of circulating ADA is actively staked across decentralized pools—demonstrating strong community engagement and network security.

With DeFi protocols beginning to deploy and NFT marketplaces gaining traction, Cardano is laying the foundation for sustainable ecosystem growth.


Frequently Asked Questions (FAQ)

Q: What makes Avalanche faster than Ethereum?
A: Avalanche uses a novel consensus protocol that achieves sub-second finality and can handle over 4,500 transactions per second—significantly faster than Ethereum’s current throughput of around 30 TPS.

Q: How does Terra maintain the stability of UST?
A: UST uses an algorithmic mechanism tied to LUNA. When UST drops below $1, users can burn $1 worth of LUNA to mint 1 UST—reducing supply and restoring the peg through arbitrage.

Q: Can Cardano support NFTs without smart contracts?
A: Yes. Cardano’s native token system allows users to create NFTs directly on the blockchain without deploying smart contracts, simplifying creation and reducing costs.

Q: Why hasn’t Ethereum’s London hard fork reduced gas fees?
A: While EIP-1559 introduced fee burning and improved predictability, it didn’t solve scalability. High demand still leads to congestion, keeping base fees elevated during peak times.

Q: Is it safe to move assets from Ethereum to other Layer 1 chains?
A: Cross-chain bridges like Avalanche Bridge are generally secure but carry risks such as smart contract vulnerabilities or temporary centralization. Always use trusted platforms and verify contract addresses.

Q: Which blockchain has the highest total value locked after Ethereum?
A: As of this writing, Binance Smart Chain holds the second-highest TVL, followed closely by Terra, which surpassed $6 billion due to strong DeFi adoption.


The Future of Layer 1 Competition

While Ethereum remains the leader in terms of developer activity and dApp diversity, its scalability limitations have opened the door for challengers. Avalanche, Terra, and Cardano each offer distinct advantages:

These networks are not just speculative plays—they’re building real ecosystems with growing user bases, increasing TVL, and expanding use cases in finance, identity, and digital ownership.
