With speed, scalability, and low fees, Solana has gained a loyal following in the crypto space. Solana’s token, SOL, fuels the network by enabling transactions and staking. The token has been on a rollercoaster of its own, reaching impressive highs and experiencing sharp declines — but it remains crucial to the network's smooth running.
What makes Solana unique is Proof of History (PoH), a cryptographic method that helps to verify a sequence of transactions at impressive speed. Many consider the feature fundamental to Solana's performance, but there's much more powering the Layer-1 blockchain.
In this article, we'll take a closer look at what Solana is, the part PoH plays in the network, compare Solana vs Ethereum, and much more.

What is Solana
Solana is a Layer-1 blockchain designed to provide fast, scalable, and secure infrastructure for decentralized applications (DApps), DeFi platforms, and NFTs. Solana’s goal is to overcome the challenges of high fee surges and slow transaction speed that other blockchains face with its architecture and consensus mechanisms.
Created by Anatoly Yakovenko in 2017, Solana was built with one main focus: overcoming the blockchain trilemma. If you've ever used Ethereum, you may have encountered times when the blockchain was congested, which led to slower transactions and higher costs. Solana handles this differently by enabling thousands of transactions per second (TPS) — up to 65,000 — with minimal fees. This high throughput makes Solana one of the fastest blockchains currently in existence.
How does the network achieve this speed? Solana uses a mix of advanced technologies, including Proof of History (PoH) and Tower Byzantine Fault Tolerance (Tower BFT). These features allow the network to process and confirm transactions quickly without compromising security.
PoH acts as a cryptographic clock for the network, which helps transactions flow efficiently, while Tower BFT makes sure the network can reach consensus quickly. This high performance has helped Solana attract users to its protocols, such as Solana Actions and Blinks, and made the network a popular choice for memecoin development. Solana's strengths have also helped attract developers and participants who want a smooth, low-cost experience.
How does Proof of History improve Solana’s speed?
We now know that PoH is a key technology underpinning Solana's performance, but what is it exactly and how does PoH support Solana's impressive speed?
What is Proof of History (PoH)?
Solana PoH isn’t just a consensus mechanism but more like a timekeeper for the network. In simpler terms, it’s a way of proving that time has passed between events on the blockchain.
Most blockchains, like Ethereum, rely on validators to confirm and agree on the order of transactions through consensus mechanisms like Proof of Stake (PoS). However, this process can slow down transaction speeds, as validators must communicate to agree on the sequence of events.
Solana’s PoH sidesteps this bottleneck. By cryptographically timestamping each transaction, PoH allows validators to know the exact order of transactions without needing to talk to each other frequently. This reduces the time and effort required to validate blocks, resulting in a faster process.
The outcome? Solana processes transactions in mere seconds, while Ethereum’s PoS, although much improved after “The Merge,” can face delays.
PoH vs PoS
To understand the advantage of PoH over PoS, consider the different approaches:
PoS focuses on validators taking turns to confirm blocks based on the amount of tokens they've staked and a certain level of consensus among them. This is energy-efficient compared to Proof of Work (PoW), but can be slower when the network is congested.
PoH removes the need for constant back-and-forth between validators to determine the sequence. With each event timestamped, transactions are validated in quick succession, leading to significantly higher throughput and lower latency.
Solana's PoH isn’t just a technical concept but the backbone of the network’s ability to outperform others in speed and efficiency. PoH helps keep Solana fast and efficient by recording events and simplifying validation.
Solana vs Ethereum: what's the difference?
When it comes to blockchain debates about speed, scalability, and usability, you can bet Solana and Ethereum will be in the mix. They’re similar platforms for DApps and smart contracts, but differ in their design, transaction speed, and user experience.
Let’s break down the differences to help better understand the Solana vs Ethereum debate.
Transaction throughput
One of the main distinctions between these blockchains is their transaction capacity. As mentioned, Solana boasts a high throughput of up to 65,000 TPS, thanks in part to the network's unique PoH consensus. This allows transactions to be processed quickly without waiting for the network to agree on the order of events.
On the other hand, Ethereum currently processes around 30 TPS on its mainnet. While the shift from PoW to PoS with “The Merge” has improved efficiency and reduced energy consumption, it hasn’t drastically changed Ethereum’s transaction throughput. However, Ethereum Layer-2 solutions like Optimism and Arbitrum are helping to bring transaction processing off the main chain, allowing for faster processing and lower fees.
Solana vs Ethereum performance
Solana: Prioritizes high-speed transactions, enabling real-time applications like DeFi platforms and NFT marketplaces to thrive with minimal delays.
Ethereum: Despite lower throughput, its robust network security and developer-friendly environment have made it the go-to for building DApps.
Transaction fees
Solana transaction fees are notably low, often just a fraction of a cent. This cost effectiveness has been a major draw for developers and users alike, who can perform multiple transactions without worrying about high costs. Low fees also make Solana attractive for high-frequency trading, gaming, and other applications requiring frequent microtransactions.
Ethereum is known for its relatively high gas fees, particularly during periods of network congestion. Gas fees are often a barrier, especially for small transactions. Layer-2 solutions and Ethereum’s roadmap aim to lower fees over time.
Ecosystem growth and developer community
Solana: Solana’s ecosystem is growing rapidly, with a surge in DApps, DeFi protocols, and NFT platforms. Fast transactions and low costs have attracted projects that need a quick, scalable environment.
Ethereum: Despite Solana’s growth, Ethereum remains the most widely adopted platform for DApps. The network's developer community, extensive documentation, and established tools like Truffle and Remix make it a favorite for developers building DApps.
Solana vs Ethereum 2024: which is better?
Choosing between Solana and Ethereum depends on your needs.
If you need speed and low transaction fees, Solana might be the better choice, particularly for applications needing fast processing.
If you’re looking for a mature ecosystem with established developer support and don’t mind higher fees for security and decentralization, Ethereum remains a solid option.
How does Solana handle cross-chain compatibility and interoperability?
One of the main goals of blockchain technology is to create decentralized platforms, but these platforms can sometimes operate like silos. Solana’s interoperability with other blockchains is crucial for the growth and connectivity of the crypto space.
Imagine transferring tokens or using assets from one blockchain to another without leaving your wallet or DApp — that’s what interoperability allows. It enables the fluid movement of digital assets, data, and functionality across different networks, making the entire crypto space more efficient and user-friendly.
Solana Wormhole bridge
Another key solution driving Solana’s cross-chain compatibility is the Wormhole bridge. The Wormhole bridge is a bi-directional communication protocol that connects Solana to a variety of other blockchains, such as Ethereum, Base, and Uniswap.
Asset transfer: You can transfer tokens, NFTs, or other digital assets between Solana and other networks in a quick and efficient manner.
Smart contract interaction: Developers can build DApps on Solana that can communicate with smart contracts on other chains, expanding the capabilities of DeFi and other applications.
With Wormhole, Solana taps into liquidity and individuals from other networks, becoming a powerful tool for multiple blockchains.
Why does this matter for DeFi and DApps?
Cross-chain functionality opens up huge possibilities:
Expanded DeFi applications: You can seamlessly trade assets, provide liquidity, and participate in yield farming across different blockchains without leaving the Solana ecosystem.
Better user experience: With multi-chain solutions, you don’t need to use many wallets or exchanges to move assets across blockchains. You can do it all through one bridge like Wormhole.
What’s the goal with multi-chain?
The goal is to boost connectivity across the crypto space. Solana’s Wormhole bridge has made progress, and the team is exploring new ways to make Solana work with other blockchains. This will make Solana easier to use, improve the mobility of your digital assets, and allow access to more DApps.
