Introduction: Many friends' first question when entering the cryptocurrency world is 'What should I buy?', but if you do not understand the underlying logic of L1 and L2, it's like trying to buy a Ferrari on a deserted island without roads. Today, we will first break down the 'foundation' and 'highways' of the crypto world. To do a good job, one must first sharpen their tools, don't you think?
šļø 1. Layer 1: The 'National Sovereignty' of the Crypto World
Layer 1 (L1) is the underlying blockchain protocol. Its core is security and final settlement.
$BTC (Bitcoin): It is digital gold, the ultimate anchor for all assets.
$ETH (Ethereum): It is the 'global settlement layer.' Although the mainnet is clunky (expensive), it is the safest asset haven, with 70% of institutional assets (RWA) locked here.
ļ»æ$SOL (Solana):The performance monster of 2026. If you seek the ultimate interactive experience, play DePIN (hardware mining) or memes, it is the first choice.
Classic achievement: Solana's Firedancer upgrade achieved tens of thousands of TPS, truly enabling blockchain to support global payments.
š 2. Layer 2: The 'Economic Special Zone' of application explosion
If L1 is the foundation, L2 is the elevated bridge built on that foundation, solving the issues of 'expensive' and 'slow.'
Base: Backed by Coinbase, it is currently the most convenient entry point for users into Web3, a sanctuary for social and consumption applications.
Arbitrum ($ARB): The den for DeFi players, possessing the deepest derivatives liquidity.
Mantle ($MNT): A modular pioneer, significantly reducing data storage costs so that your transaction fees become almost negligible.
š° 2026 recommendations for avoiding pitfalls and opportunities for different groups
1. Crypto newcomers (Newbies) š£
Suggestion: Avoid touching low liquidity niche L1s.
Configuration: 80% mainstream assets ($BTC / $ETH / $BNB) + 20% top L2 ecosystem tokens.
Action: Prioritize experiencing top applications on Base or Solana to feel the 'smooth' trading.
2. Advanced players (Degens) ā”
Suggestion: Focus on 'cross-chain interoperability' protocols.
Opportunity: Look for vertical field opportunities that are expanding from L2 to L3 (such as gaming chains, AI dedicated chains).
3. Conservative faction (Pros) š”ļø
Suggestion: Pay attention to Restaking.
Opportunity: Earn multiple yields on Ethereum L1 through protocols like EigenLayer while ensuring principal safety.
š Final remarks
Understanding L1 and L2 gives you clarity on the market's framework. But having the road, what vehicles run on it is the key to doubling wealth in 2026.
ļ»æTomorrow, I will delve into this year's hottest two 'engines': RWA (Real World Assets on-chain) and AI Agents (AI agent ecosystem).
