Solana is often hailed as the next Ethereum. For any new cryptocurrency, these are substantial claims to live up to, but supporters believe Solana has what it takes to challenge the reigning king of altcoins. This article explains what Solana is and how it works. It also discusses how Solana differs from Ethereum and explores the types of decentralized applications (dApps) running on the Solana network.
Understanding Solana and SOL
Like Ethereum, Solana is both a cryptocurrency and a platform for running smart contracts and decentralized applications. Many consider it a potential "Ethereum killer" because it offers greater speed and sustainability. Developers envision Solana's rapid transaction speeds and low fees eventually enabling it to compete with centralized payment networks like Visa.
Who Founded Solana?
Solana was founded by Anatoly Yakovenko, who began his career at Qualcomm. It was there that he met Greg Fitzgerald, and the two later partnered with Eric Williams to establish Solana Labs. The project raised over $25 million through an Initial Coin Offering (ICO) on Coinlist in 2020. Around this time, Solana’s beta mainnet launched, offering basic smart contract functionality and transaction capabilities.
How Does Solana Work?
Proof of History (PoH)
Cryptocurrencies like Bitcoin and Ethereum use a consensus mechanism known as Proof of Work (PoW). This method relies on miners to verify transactions and produce new coins. Some newer cryptocurrencies, such as Cardano and Algorand, use a different consensus algorithm called Proof of Stake (PoS). In this system, the network randomly selects users who have "staked" a certain amount of cryptocurrency to validate transactions and rewards them with newly minted coins.
Regardless of the mechanism, all computers on the network need to reach a consensus on specific details, such as when a transaction occurred. This can be a time-consuming process. What makes Solana unique is its combination of PoS and an innovative system called Proof of History (PoH), which exponentially accelerates this process.
Solana’s founder and CEO, Anatoly Yakovenko, describes PoH as "a historical record that proves that an event occurred at a specific moment in time." This mechanism acts like a decentralized clock, designed to synchronize time across all computers in the network without requiring each one to agree individually.
Imagine a series of photographs capturing a vase falling and shattering into a thousand pieces. Each photo freezes a specific moment, showing the vase’s exact position and the distribution of fragments. From these timely snapshots, a sequence of events can be quickly established. This is similar to how PoH operates.
Key Insight
Proof of History (PoH) is a cryptographic clock that allows all computers in the network to maintain synchronization and validate transactions without waiting for universal agreement. This enables the Solana network to operate at lightning speed.
Solana vs. Ethereum: Key Differences
Solana and Ethereum share similar core functionalities, but there are crucial differences between the two cryptocurrencies. Ethereum, launched in 2015, was the first platform for smart contracts and decentralized applications. It also laid the foundation for the entire decentralized finance (DeFi) industry. Today, Ethereum processes about 1.3 million transactions daily. However, Ethereum was not originally designed to handle such high volume. As a result, transaction times can be slow, and fees are often expensive.
Ethereum developers are working on a solution—Ethereum 2.0—which promises significant improvements, including a shift to PoS. But several competitors, like Solana, launched in 2020, offer similar features and are already scalable. Let’s examine the main differences between Solana and Ethereum.
Transaction Speed
Solana’s primary innovation lies in its speed. The average block time is around 400 milliseconds, compared to Ethereum’s 13–15 seconds. Solana claims it can handle up to 50,000 transactions per second (TPS), while the current version of Ethereum manages 15 TPS or less. It’s worth noting that the Ethereum 2.0 upgrade aims to increase the network’s transaction throughput to over 100,000 TPS.
Cost Efficiency
Thanks to Solana’s speed, network congestion and fees remain low. The average transaction cost on the network is just $0.00025, attracting both users and developers seeking a blockchain platform for building projects. On the Ethereum network, average transaction fees range from $3 to $70, depending on congestion levels. The Ethereum 2.0 update is designed to significantly reduce these costs.
Sustainability
The PoW consensus mechanism used by Bitcoin and Ethereum requires substantial energy to maintain. Solana, on the other hand, uses a PoS mechanism, which is more energy-efficient and sustainable. Interestingly, part of Ethereum’s 2.0 network upgrade includes a shift from PoW to PoS, which will greatly reduce its energy consumption.
Key Insight
Solana is faster, cheaper, and more energy-efficient than Ethereum. However, the Ethereum 2.0 update aims to level the playing field by making the network faster, more affordable, and greener.
What Is the SOL Token?
SOL is Solana’s native token, and it serves multiple purposes. Users can delegate their SOL to validators—computers that process transactions and run the decentralized network—and receive a portion of the rewards in return. SOL also acts as a governance token, meaning holders can vote on future upgrades and governance proposals submitted by the community. Finally, users can pay transaction fees with SOL.
What Decentralized Applications Run on Solana?
Solana’s ecosystem is diverse and extensive, encompassing gaming, NFTs, music applications, and even decentralized exchanges. Let’s explore some of these applications in more detail.
Star Atlas
Star Atlas is a multiplayer game developed on the Solana blockchain. It allows players to inhabit and interact with a virtual universe in multiple ways, including space exploration, political strategy, combat, and trading. Star Atlas is built on a real-money economy and NFT assets. Players can buy and trade in-game assets such as clothing, weapons, spaceships, and land.
Serum
Serum is a decentralized exchange (DEX) built on the Solana network. It allows traders to buy and sell cryptocurrencies without relying on a trusted third party, such as a centralized exchange (which can be vulnerable to hacks and exit scams). Serum claims to offer faster speeds and lower fees compared to many other exchanges in the DeFi space.
Audius
Audius is a music platform designed to return power to content creators. It enables creators to produce creative works registered on the Audius network—immutable and time-stamped. Music enthusiasts can stream and share music directly from the platform, similar to Spotify. Audius aims to create a fully decentralized ecosystem comprising musicians, developers, and listeners.
Did You Know?
The Audius platform itself wasn’t originally built on Solana but recently migrated to the Solana blockchain. The creators believed Solana was the only network capable of meeting their demands for speed, low cost, and censorship resistance.
How to Buy Solana (SOL)
