What Is SOL Coin? Why Is It Called the "Ethereum Killer"? A Complete Guide to Solana

·

Solana has rapidly emerged as one of the most influential blockchains in the cryptocurrency space. Known for its blazing-fast transaction speeds and low fees, SOL — the native token of the Solana blockchain — has earned a top spot among digital assets. Often dubbed the “Ethereum killer,” Solana aims to solve some of the core limitations of older blockchains like Ethereum, including network congestion, high gas fees, and slow transaction times.

This comprehensive guide explores what SOL is, how Solana works, its key advantages and challenges, ecosystem applications, and how it compares to Ethereum. Whether you're a beginner or an experienced crypto enthusiast, you'll gain valuable insights into one of the most innovative Layer 1 blockchains today.


What Is SOL?

SOL is the native cryptocurrency of the Solana blockchain, serving as the backbone of its decentralized ecosystem. Launched in 2020 by Anatoly Yakovenko and Raj Gokal through Solana Labs, Solana was designed from the ground up to support high-performance decentralized applications (dApps) with minimal latency and cost.

SOL plays several critical roles within the network:

With a total supply capped at approximately 550 million tokens, SOL consistently ranks among the top 10 cryptocurrencies by market capitalization. As of early 2025, one SOL trades around $216.68, reflecting strong investor confidence and growing adoption.

Key Features That Make Solana Stand Out

Solana differentiates itself through a unique combination of speed, efficiency, and scalability. Here's what sets it apart:

⚡ High Speed and Scalability

Solana claims to be the world’s fastest high-performance blockchain, capable of processing up to 50,000 transactions per second (TPS) with an average block time of just 400 milliseconds. This performance far exceeds Ethereum’s current capacity of about 15–30 TPS, making Solana ideal for real-time applications such as gaming and micropayments.

The secret behind this speed lies in its hybrid consensus mechanism combining Proof of Stake (PoS) and Proof of History (PoH). While PoS secures the network via staking, PoH introduces a cryptographic clock that timestamps transactions before they’re added to the blockchain — significantly reducing validation time.

💡 Energy Efficiency

Unlike proof-of-work chains that rely on energy-intensive mining, Solana uses a green alternative. By eliminating mining and relying on PoS + PoH, Solana consumes less energy per transaction than a single Google search. This makes it not only faster but also more environmentally sustainable.

💸 Low Transaction Costs

Transaction fees on Solana are exceptionally low — often just a fraction of a cent. For example:

These ultra-low fees make Solana accessible to everyday users and small businesses alike, removing financial barriers common on other networks.


Challenges Facing Solana

Despite its technological edge, Solana faces notable hurdles that impact trust and long-term reliability.

🛑 Network Outages

Since its launch, Solana has experienced several major network outages due to consensus failures or transaction overload:

While each incident was eventually resolved, repeated outages raise concerns about decentralization and resilience under stress — especially when compared to more battle-tested networks like Ethereum.

⚖️ Regulatory Uncertainty

In June 2023, the U.S. Securities and Exchange Commission (SEC) classified SOL as a security. This decision triggered a nearly 30% price drop within 24 hours and led platforms like Robinhood to temporarily suspend SOL trading. Although legal debates continue, regulatory scrutiny remains a significant risk for Solana’s global expansion.


Solana’s Growing Ecosystem

Solana’s high throughput and low costs have attracted developers across multiple sectors. Today, its ecosystem spans DeFi, NFTs, GameFi, payments, and DAOs.

🎮 GameFi on Solana

Solana provides a robust toolkit for building Web3 games with seamless on-chain interactions. Popular titles include:

These games leverage Solana’s speed to deliver near-instant gameplay actions without breaking the bank.

🖼️ NFTs on Solana

With over 32 million NFTs minted on-chain and minimal minting costs, Solana has become a hotspot for digital artists and collectors. Leading marketplaces include:

The affordability and speed make it easier than ever to create, buy, and sell digital art.

💸 DeFi on Solana

Solana hosts over 160 DeFi projects, with more than $11 billion in total value locked (TVL)**. Daily trading volume exceeds **$430 million, powered by protocols like:

Partnerships with major players like Pyth and OKX further strengthen its position in decentralized finance.

💵 Payments via Solana

Over $700 million in USDC circulates on Solana daily, supported by over 280,000 active users. Its near-zero fees make it ideal for remittances and microtransactions. Key payment partners include:

This infrastructure positions Solana as a viable alternative to traditional payment systems.

🏛️ DAOs on Solana

More than 140 DAOs operate on Solana, collectively managing close to $1 billion in community funds. These decentralized organizations use Solana’s fast finality to vote on proposals and distribute grants efficiently.


SOL vs ETH: How Do They Compare?

Frequently Asked Questions (FAQ)

Q: Is SOL a coin or a token?
A: SOL is a coin because it is the native cryptocurrency of the Solana blockchain. Tokens are built on existing blockchains (like ERC-20 tokens on Ethereum), whereas coins power their own networks.

Q: What makes Solana so fast?
A: Solana combines Proof of Stake (PoS) with a novel Proof of History (PoH) mechanism that creates a verifiable timestamp for transactions before consensus, dramatically speeding up processing.

Q: Can I stake SOL?
A: Yes! You can stake SOL using wallets like Phantom or Backpack to help secure the network and earn annual yields typically ranging from 5% to 7%.

Q: Why is Solana called the “Ethereum killer”?
A: Because it addresses Ethereum’s main pain points — slow speeds and high fees — with superior performance and lower costs. However, “killer” doesn’t mean replacement; both networks coexist and serve different needs.

Q: Where can I buy SOL?
A: SOL is widely available on major exchanges such as Binance, Coinbase, Kraken, and OKX. Always ensure you're using secure platforms with strong regulatory compliance.

Q: Is Solana decentralized enough?
A: This is debated. While technically decentralized, some critics argue that validator requirements favor well-resourced entities. Ongoing improvements aim to enhance accessibility and node distribution.
