Compare 13 Layer 1 blockchains including BTC, ETH, SOL, ADA — architecture, consensus mechanisms, and ecosystem growth.
Layer 1 blockchains form the foundation of the crypto ecosystem, handling transaction validation, consensus, and data storage. Major L1 chains include Bitcoin, Ethereum, Solana, and Cardano. Each chain makes different trade-offs between decentralization, speed, and security. Choosing which L1 to invest in requires evaluating their technology roadmaps, developer ecosystems, and real-world adoption.
Bitcoin is the world's first decentralized cryptocurrency, created by Satoshi Nakamoto in 2009, launching the blockchain revolution.
Ethereum is the world's largest smart contract platform, powering DeFi, NFTs, and decentralized applications.
Solana is a high-performance blockchain known for blazing-fast transactions and low fees, popular for DeFi and NFTs.
Cardano is an academic research-driven blockchain platform emphasizing security, scalability, and sustainability.
Avalanche is a high-speed smart contract platform known for sub-second finality and subnet architecture for enterprise blockchain applications.
Polkadot is a cross-chain interoperability protocol enabling secure data and asset exchange between different blockchains.
TRON is a decentralized content sharing and entertainment platform, known for high throughput and stablecoin transfers.
Litecoin is known as 'digital silver,' an early Bitcoin fork offering faster confirmations and lower fees.
Bitcoin Cash is a Bitcoin hard fork focused on increasing transaction capacity and reducing payment fees.
NEAR Protocol is a user-friendly Layer 1 blockchain achieving high scalability through sharding technology.
Aptos is a next-generation Layer 1 blockchain built by former Meta team members, developed using the Move language.
Ethereum Classic is Ethereum's original chain, preserved after the 2016 DAO incident when the community split over reversing transactions.
Sui is a next-generation high-performance Layer 1 blockchain by former Meta team members, using Move language and an object-oriented model.
A Layer 1 is an independent base blockchain network, such as Bitcoin or Ethereum. They have their own consensus mechanisms and validator nodes, processing transactions without relying on other blockchains.
Bitcoin and Ethereum remain the largest L1 chains by market cap. Solana is known for high speed and low fees, Cardano follows an academic approach, and Avalanche offers a subnet architecture. Investors should choose based on their risk tolerance.
Layer 1 is the base blockchain network (e.g., Ethereum), while Layer 2 is a scaling solution built on top of L1 (e.g., Arbitrum, Optimism). L2s inherit L1 security while offering faster and cheaper transactions.
