Layer 1 blockchains

What are Layer 1 Blockchains?

Imagine the internet. It has a foundation – the physical cables, servers, and protocols that make everything work. In the world of cryptocurrency, Layer 1 blockchains are *that* foundation. They are the underlying infrastructure that supports all the cool stuff like DeFi, NFTs, and just sending and receiving cryptocurrency.

Think of them as the original, base-level blockchains. They process and validate transactions directly on their own network. They handle the core functions of a blockchain: security, consensus (how everyone agrees on what's true), and data availability. Without a strong Layer 1, everything built on top would crumble.

Key Layer 1 Blockchains

There are several major players in the Layer 1 space. Here are a few of the most well-known:

• **Bitcoin (BTC):** The very first cryptocurrency. Known for its security and decentralization, but sometimes slower and more expensive for transactions. You can learn more about Bitcoin and its history here.
• **Ethereum (ETH):** More than just a cryptocurrency; it's a platform for building decentralized applications (dApps). Ethereum introduced smart contracts, which are self-executing agreements written into code. It’s currently undergoing significant upgrades to improve its scalability.
• **Binance Smart Chain (BSC):** Developed by the Binance exchange Register now. It's designed to be faster and cheaper than Ethereum, but often considered less decentralized.
• **Solana (SOL):** Known for its incredibly fast transaction speeds and low fees. It uses a unique consensus mechanism called Proof of History.
• **Cardano (ADA):** Focuses on a research-driven approach and aims to be a more sustainable and scalable blockchain.
• **Avalanche (AVAX):** Offers fast transaction finality and the ability to create custom blockchains.

How Layer 1 Blockchains Work: A Simple Explanation

All blockchains, including Layer 1s, work using a few core concepts:

1. **Transactions:** Someone wants to send cryptocurrency to someone else. 2. **Blocks:** Transactions are grouped together into “blocks.” 3. **Validation:** "Miners" (in Bitcoin's case) or "Validators" (in other blockchains) verify these transactions and ensure they are legitimate. They do this using complex mathematical problems and a process called consensus mechanism. 4. **Chain:** Once validated, the block is added to the blockchain, forming a permanent, tamper-proof record.

Different Layer 1 blockchains use different methods for validation. Bitcoin uses "Proof of Work" (PoW), which requires significant computing power. Ethereum is transitioning to "Proof of Stake" (PoS), which relies on users "staking" their cryptocurrency to validate transactions. Consensus Mechanism is a key area to study.

Layer 1 vs. Layer 2

You’ll often hear about “Layer 2” solutions. It’s important to understand the difference.

• **Layer 1:** The base blockchain (like Bitcoin or Ethereum). Handles the core security and validation.
• **Layer 2:** Built *on top* of Layer 1. Designed to improve scalability and reduce transaction fees. Think of it as adding extra lanes to a highway to ease congestion. Examples include Lightning Network (for Bitcoin) and Polygon (for Ethereum).

Here's a comparison table:

Feature	Layer 1	Layer 2
Primary Function	Core infrastructure & security	Scalability & reducing fees
Security	Highly secure (typically)	Relies on Layer 1 security
Transaction Speed	Can be slower	Generally faster
Fees	Can be higher	Generally lower

Trading Layer 1 Tokens

Trading Layer 1 tokens is similar to trading any other cryptocurrency. Here's a basic overview:

1. **Choose an Exchange:** Select a reputable cryptocurrency exchange like Binance Register now, Bybit Start trading, BingX Join BingX, Bybit Open account, or BitMEX BitMEX. 2. **Fund Your Account:** Deposit cryptocurrency or fiat currency (USD, EUR, etc.) into your exchange account. 3. **Find the Trading Pair:** Look for the trading pair you want (e.g., BTC/USDT, ETH/BTC). 4. **Place Your Order:** Choose your order type (e.g., market order, limit order) and specify the amount you want to buy or sell. Learn more about order types here. 5. **Monitor Your Trade:** Keep an eye on your trade and adjust your strategy as needed. Technical Analysis can be helpful.

Factors to Consider When Trading Layer 1 Tokens

• **Market Capitalization:** The total value of all coins in circulation. Generally, larger market caps are less volatile.
• **Technology & Innovation:** What problems is the Layer 1 blockchain solving? Is it constantly innovating?
• **Developer Activity:** A strong developer community indicates a healthy project.
• **Adoption Rate:** How many users and applications are using the blockchain?
• **Tokenomics:** The economics of the token. How is it distributed? What is its supply schedule? Understanding tokenomics is crucial.
• **Trading Volume:** Higher trading volume usually indicates more liquidity and easier to execute trades. Explore Trading Volume Analysis techniques.

Here's a comparison of common Layer 1 blockchains:

Blockchain	Consensus Mechanism	Transaction Speed (approx.)	Average Transaction Fee (approx.)
Bitcoin (BTC)	Proof of Work (PoW)	7 transactions per second	$5 - $20
Ethereum (ETH)	Proof of Stake (PoS) (transitioning)	15-45 transactions per second	$2 - $50 (highly variable)
Solana (SOL)	Proof of History (PoH)	50,000 transactions per second	$0.00025
Cardano (ADA)	Proof of Stake (PoS)	250 transactions per second	$0.10 - $0.50

Risks & Further Learning

Investing in Layer 1 blockchains, like all cryptocurrency investments, carries risk. Prices can be volatile, and projects can fail. Always do your own research (DYOR) before investing.
