Every week we provide insights into popular assets and hot topics in crypto, so you can easily learn more about the crypto market in bite‑sized pieces.
In this Crypto in Focus, we dive into Layer‑1 Blockchains - the foundational layer where decentralized applications (dApps) and crypto services are built.
What Are Layer-1 Blockchains
Layer‑1 blockchains are the base networks that host decentralized applications, smart contracts, and other services - think of them like the operating system of your smartphone, while the dApps are the apps you install.
Since the rise of Ethereum, many “Ethereum killers” have entered the race. These Layer‑1 chains aim to gain market share by attracting developers and users through scalability, lower fees, or unique features. Which chain wins out is still very much an open question.
Here are three key Layer‑1 blockchains that are shaping the future - all available in the Change app: Ethereum, Solana, and NEAR.
Ethereum (ETH)
Ethereum was the first smart contract Layer‑1 blockchain and remains one of the most widely used. It has a strong developer community, thousands of dApps, and a large user base. Its long track record gives it a significant advantage.
That said, Ethereum still faces scalability challenges, and many of its scaling solutions rely on Layer‑2 networks, which come with their own trade‑offs.
Notably, spot Ethereum ETFs have already launched in several markets. For example, VanEck has a spot ETH ETF.
Solana (SOL)
Solana was built specifically to address scalability: it offers extremely fast transactions and very low fees, making it very attractive for many retail users.
There is also significant institutional interest: several asset managers have filed for spot Solana ETFs.
Regulators reportedly set a key deadline for ETF refilings and possible approval.
However, others suggest the timeline might stretch - some analysts predict final decisions could come in 2026.
NEAR (NEAR)
NEAR is another Layer‑1 chain focused on speed and low transaction costs. It’s gaining traction thanks to its connections to AI — one of its co-founders, Illia Polosukhin, previously worked on research in AI.
This AI alignment is becoming a strong differentiator for NEAR, helping it appeal to developers building next-gen decentralized, intelligent applications.
Why Layer‑1 Blockchains Matter for Investors
- Scalability & Fees: Different Layer‑1s solve these pain points in different ways (speed, cost, technology).
- Ecosystem Growth: Chains with more developers and stronger dApp ecosystems tend to attract more users, which can drive demand.
- Diversification: Rather than putting all your risk on one blockchain (e.g., just ETH), you can diversify across multiple Layer‑1s.
- ETF Potential: With spot Solana ETFs in the pipeline, Layer‑1 exposure may become more accessible via regulated financial products.
