Layer 1 Crypto 2025: Which Blockchain Dominates Your Portfolio?

The blockchain world pivots on Layer 1—the foundation everything else builds upon. While Layer 2 solutions grab headlines for speed and cost, they’re all just riding on the security and finality that Layer 1 blockchains provide. As we scan the 2025 crypto landscape, 15 major Layer 1 projects are reshaping what’s possible. Let’s cut through the noise and see which ones actually matter.

The Layer 1 Foundation: Why Base Layer Blockchains Still Rule

Layer 1 blockchains are the bedrock. They handle transaction finality, enforce security through consensus mechanisms like Proof of Stake or Proof of Work, and manage the native tokens that fuel everything. Unlike Layer 2 solutions that depend on their parent chains for security, Layer 1 networks stand independent—they make their own rules and bear their own weight.

What makes them unique? First, they’re decentralized by design. No single entity controls them. Second, transactions are permanent—what gets recorded stays recorded. Third, they support native tokens that serve multiple roles: paying for gas, securing the network through staking, and enabling governance. These three pillars explain why Layer 1 dominance persists even as scaling solutions multiply.

The real question isn’t whether Layer 1 matters—it clearly does. The question is which Layer 1 actually delivers on its promises in 2025.

Performance vs. Adoption: The Layer 1 Trade-off

Every Layer 1 project faces the same dilemma: maximize transaction speed and efficiency while maintaining security and decentralization. The winners are those that nail this balance.

Bitcoin ($88.67K, -10.84% YoY) remains the security champion. TVL sits at $1.1 billion on what’s primarily a payment network. In 2023, Bitcoin unlocked a major unlock—the Ordinals protocol let developers mint NFTs directly on-chain. Bitcoin Layer-2 solutions like Stacks emerged to add smart contract capabilities, finally giving Bitcoin developers room to build.

Ethereum ($2.97K, -15.10% YoY) is the adoption heavyweight with $49 billion in TVL and over 3,000 active dApps. The developer community remains unmatched. The recent push toward Ethereum 2.0 focuses on Layer 2 scaling solutions like rollups—not because Layer 1 is broken, but because Layer 1 excellence enables Layer 2 innovation.

Solana ($123.90, -37.26% YoY) flipped the script with Proof of History consensus, achieving near-instant finality. TVL of $3.46 billion masks the real story: 2,000+ validators and a thriving ecosystem spanning DeFi (Marinade Finance, Jito), NFTs, and gaming. The BONK airdrop phenomenon demonstrated just how much liquidity flows through Solana when momentum builds.

BNB Chain ($840.20, +19.60% YoY) carved out territory as Ethereum’s faster sibling. With 1,300+ active dApps and $5.2 billion TVL, it’s the practical choice for developers already familiar with EVM tools. Market cap of $115.72B signals serious institutional interest.

The Emerging Challengers: Newer Layer 1 Cryptos Worth Watching

Fresh Layer 1 entrants are disrupting established hierarchies with radical rethinks of what blockchain should do.

Kaspa ($0.05, -62.07% YoY) introduced GHOSTDAG consensus—a breakthrough that enables simultaneous block production without sacrificing security. The 1,800% price surge in 2023 reflected genuine technical progress. Transitioning from GoLang to Rust unlocked hardware efficiency gains that matter.

Sei ($0.11, -75.49% YoY) laser-focused on one problem: making DEXs faster. The built-in matching engine and order book optimization turned DeFi trading into a first-class Layer 1 citizen rather than an afterthought. With 6,000% gains in 2023 before the correction, the market clearly saw something.

Aptos ($APT price not in latest data, -27% YoY) and Sui ($1.41, -68.76% YoY) both leveraged the Move programming language to rethink smart contract safety. Move forces developers to reason about asset ownership at compile time—fewer hacks result. Both are scaling transaction volumes to hundreds of thousands daily.

The Specialized Layer 1 Landscape

Some Layer 1 projects aren’t trying to be everything. They’re betting on dominance in specific verticals.

The Open Network (TON) ($1.53, -74.18% YoY) rides Telegram’s infrastructure. The March 2024 announcement that Telegram would distribute 50% of ad revenue through TON sparked a 40% surge. If Telegram goes public and deepens blockchain integration, TON’s utility case shifts from theoretical to lived experience for 500 million+ users.

Internet Computer (ICP) ($3.04, -72.86% YoY) aims to replace cloud infrastructure with on-chain compute. Websockets enable real-time apps. HTTPS outcalls break the oracle problem by letting smart contracts reach Web 2 directly. If this vision resonates, ICP’s $88 million TVL could explode.

Kava ($0.08, -84.05% YoY) combines Cosmos scalability with EVM compatibility—a bridge between ecosystems. The $193 million TVL reflects growing appetite for multi-chain infrastructure that doesn’t force ecosystem lock-in.

Interoperability: The Next Layer 1 Frontier

Fragmentation was 2023’s biggest Layer 1 challenge—too many chains, too many siloed communities. 2025 is when that breaks.

Polkadot ($DOT price update pending, -0.39% YoY) enforces shared security across parachains. The new Nomination Pools boosted staking 49%, broadening participation beyond whales.

Cosmos ($2.02, -70.86% YoY) went the opposite direction: each chain remains sovereign, but the Inter-Blockchain Communication protocol lets them talk. The Interchain Security feature brought smaller chains under Cosmos Hub’s security umbrella.

ZetaChain ($0.07, -88.83% YoY) aims for true omnichain capability—smart contracts that execute across any blockchain without wrapping or bridges. Over 6.3 million cross-chain transactions on testnet proved the concept works at scale.

The Data Reality: 2025 Layer 1 Performance Update

Original article data has aged. Here’s what actually matters now:

The 2024-2025 correction hit alternative Layer 1s hard. But price ≠ merit. Technological progress continued regardless of market sentiment.

Layer 1 vs. Layer 2: Stop Treating Them as Competitors

This is the misconception that won’t die. Layer 2 doesn’t replace Layer 1—it extends Layer 1. Every Layer 2 transaction ultimately settles on its Layer 1 parent for finality. The relationship is symbiotic, not competitive.

Ethereum’s Layer 2 solutions (Optimism, Arbitrum) only work because Ethereum’s Layer 1 provides rock-solid security. Bitcoin’s Layer 2 (Stacks) only matters because Bitcoin’s Layer 1 never got hacked. The security inherited from Layer 1 is the entire value prop of Layer 2.

What’s evolving is specialization. Layer 1 projects increasingly optimize for security and finality rather than chasing throughput metrics. Sharding in Ethereum doesn’t mean faster transactions for users—it means more reliable Layer 2 settlement. That’s the real scaling story.

Which Layer 1 Crypto Should You Actually Watch?

The honest answer: it depends on your thesis.

For maximum security and network effect: Bitcoin and Ethereum remain unmatched. They’re not the fastest, but they’re the most credibly neutral and most resistant to failure.

For DeFi efficiency: Solana’s recovery trajectory and BNB Chain’s practical EVM implementation offer genuine advantages over Ethereum for certain applications.

For innovation: Kaspa, Aptos, and Sui are pushing technical boundaries. The corrections don’t invalidate their progress.

For ecosystem potential: TON’s Telegram integration and ICP’s compute vision offer asymmetric upside if their narratives align with real adoption.

For interoperability: Polkadot, Cosmos, and ZetaChain represent the future where chains talk to each other without losing sovereignty.

The Layer 1 crypto space isn’t consolidating around one winner. It’s fragmenting into specialized niches. Monolithic chains are giving way to modular ecosystems where Layer 1 handles settlement, Layer 2 handles throughput, and rollups handle specific verticals.

What’s Next for Layer 1 in 2025

Expect three major trends:

1. Security obsession: After the exploit season, Layer 1 projects are doubling down on formal verification and conservative consensus upgrades.

2. Vertical integration: Layer 1 projects increasingly own their vertical (Sei for DeFi, TON for messaging, ICP for compute) rather than pretending to be general-purpose.

3. Economic consolidation: Only the largest Layer 1 networks will sustain independent validator ecosystems. Smaller chains will increasingly lean on shared security from larger parents.

The 2025 Layer 1 landscape is mature but still innovating. The winners aren’t decided. But the Layer 1 crypto category itself? That’s not going anywhere.
