When you hear Layer 1 blockchain, the foundational network that processes transactions directly on its own chain, without relying on secondary layers. Also known as base layer blockchain, it's the backbone of every major cryptocurrency—from Bitcoin’s simple transfers to Ethereum’s smart contracts. This isn’t theory. It’s the actual network your wallet talks to when you send ETH, buy an NFT, or stake SOL. If a blockchain can’t handle its own traffic, it breaks—slow fees, stuck transactions, failed trades. That’s why Layer 1 matters more than you think.
Not all Layer 1 blockchains are built the same. Bitcoin, the original Layer 1, prioritizes security and decentralization over speed. It settles one transaction every few minutes. Ethereum, a more flexible Layer 1 that runs code, not just payments, changed everything by letting developers build apps on top. Then came Solana, a high-speed Layer 1 designed to compete with traditional payment networks, processing tens of thousands of transactions per second. Each has trade-offs: Bitcoin is slow but unbreakable. Solana is fast but has crashed under pressure. Ethereum is evolving but still pays high fees during peak times.
Layer 1 blockchains don’t exist in a vacuum. They’re shaped by what users need and what developers build. You’ll see this in the posts below—how North Korea’s hackers target Ethereum-based DeFi apps, how Solana-based memecoins like XING and SHEGEN explode without utility, how GMX uses Arbitrum (a Layer 2) to cut fees but still depends on Ethereum’s Layer 1 for security. Even the blockchain payment speed gains you read about? Those rely on Layer 1s that can process transactions fast enough to make stablecoin transfers cheaper than banks. And when Thailand bans foreign P2P platforms, it’s because Layer 1s like Binance Chain or Solana let users bypass local banking controls.
What you won’t find here are vague promises of "the next big thing." You’ll find real examples of Layer 1s that worked, failed, or got exploited. You’ll see how Inery’s $11 daily volume exposes a Layer 1 with no users, how Rook’s collapse proves that even smart contract Layer 1s can die without adoption, and how the Lazarus Group steals millions because Layer 1s can’t stop human error. This isn’t about hype. It’s about what holds up—and what doesn’t—when real money is on the line.
Below, you’ll find deep dives into exactly that: how Layer 1 blockchains power everything from NFT royalties to crypto theft, from regulatory crackdowns to unbanked users in Africa. No fluff. No jargon. Just what works, what breaks, and why.
Layer 1 blockchains like Ethereum are secure but slow. Layer 2 solutions like Arbitrum and zkSync offer fast, cheap transactions by building on top. In 2025, most activity happens on Layer 2-but Layer 1 remains the foundation.
