What is Solana?

Solana is a high-performance blockchain designed to address the key challenges of speed, scalability, and low-cost transactions. It was founded in 2017 by Anatoly Yakovenko, a former Qualcomm engineer, who aimed to solve the issues of slow transaction times and high fees in earlier blockchain networks like Bitcoin and Ethereum.

Solana's mission is to provide a fast, secure, and scalable network that can handle thousands of transactions per second without compromising decentralization. This is made possible by its unique consensus mechanism, Proof of History (PoH), which reduces the need for validators to communicate as frequently as in other blockchains. This, combined with Proof of Stake (PoS), allows Solana to achieve much higher speeds than Bitcoin and Ethereum.

Key features that make Solana stand out

Proof of History (PoH)

Solana’s Proof of History (PoH) is a revolutionary concept in blockchain technology. It timestamps transactions before they are added to the blockchain, creating a verifiable order of events. By establishing this sequence of events, validators don’t need to constantly communicate to confirm the sequence of transactions, making the network much faster. This feature is a game-changer as it helps Solana process more transactions per second without sacrificing security or decentralization.

Proof of Stake (PoS)

Solana also uses Proof of Stake (PoS), which improves the network’s security and energy efficiency. In a PoS system, validators are chosen based on the amount of SOL they have staked, which encourages good behavior. Combining PoH and PoS allows Solana to secure the network while consuming less energy than traditional Proof-of-work systems like Bitcoin, making Solana both fast and eco-friendly.

High transaction speed

One of Solana’s major selling points is its high transaction speed. As of 2024, Solana can process around 65,000 transactions per second (TPS) on testnet. However, as stated above, in real-world conditions, this number tends to be much lower, around 200 to 400 transactions per second (TPS) on average, though it can surge to over 2,000 TPS during periods of high demand. The high throughput makes Solana ideal for decentralized applications (dApps) that require quick transaction processing and scalability, such as DeFi platforms and NFT marketplaces.

Low transaction costs

Solana’s low transaction costs set it apart from other blockchains, as developers and users alike are drawn to the platform. This makes Solana a strong competitor for projects that require frequent or high-volume transactions. It’s one of the main reasons developers choose Solana over more expensive blockchains like Ethereum, where gas fees can spike during network congestion.

Solana’s ecosystem in 2024

DeFi applications

Due to its fast transaction speeds and low fees, Solana has become a strong player in the DeFi (Decentralized Finance) space. As of 2024, DeFi protocols like Marinade and Carrot are driving innovation on the platform. Marinade provides a liquid staking solution, allowing users to stake SOL while still having access to liquidity. Carrot offers real-time APY and boosts user engagement in decentralized finance. These applications contribute to Solana's growing Total Value Locked (TVL), reflecting its increasing adoption of its DeFi ecosystem.

NFTs on Solana

Solana's speed and low fees make it attractive to NFT creators and collectors. High gas fees on Ethereum have pushed many creators to migrate to Solana, where transaction costs are lower and minting NFTs is more accessible. Popular platforms like Magic Eden have flourished, and the ecosystem continues to attract new artists and projects. Speed and cost-efficiency are crucial to Solana's success in the NFT space.

Mobile integration

In a move toward integrating blockchain technology into daily life, Solana launched its Saga Mobile, a smartphone with built-in Solana support. This mobile device allows users to manage their crypto assets, interact with dApps, and participate in blockchain activities without needing external applications. The Saga phone aims to make blockchain more accessible, and it saw strong initial demand after its release. Additionally, Solana has introduced a second phone, the Seeker, which has already garnered pre-orders for its anticipated 2025 release. These innovations are helping push blockchain adoption further into mainstream technology.

Institutional adoption

Solana has gained traction with institutional players. Companies like Franklin Templeton and Citi have launched financial services on the Solana network, while Société Générale introduced a MiCA-compliant Euro stablecoin on the platform. In May 2024, it was also revealed that the PayPal USD (PYUSD) stablecoin is available on Solana. This level of adoption from traditional finance players solidifies Solana’s credibility as a reliable blockchain for more than just decentralized applications. It’s becoming a critical infrastructure for financial institutions looking to leverage blockchain technology for efficiency and security.

How Solana is addressing scalability and security challenges

Fire Dancer

Solana has introduced Fire Dancer, a new validator client designed to enhance network performance and security significantly. Developed in collaboration with Jump Crypto, Fire Dancer increases throughput and minimizes latency, helping Solana process even more transactions per second while maintaining security. This validator client diversifies the network by adding a second, independently built validator, reducing the risk of network vulnerabilities caused by single points of failure.

ZK compression

Solana uses Zero-Knowledge (ZK) Compression to dramatically reduce state costs on the blockchain. ZK Compression works by condensing large amounts of data into smaller, verifiable proofs, which reduces the burden on the blockchain. This technology helps scale Solana further by making transactions more efficient and less expensive. ZK Compression is especially beneficial for dApps and other high-transaction environments, allowing them to operate more smoothly without overloading the network.

Solana's resilience and outages

In the past, Solana experienced notable network outages in September 2021 and January 2022. These interruptions raised concerns about the blockchain's reliability, with the network going offline for as long as 17 hours during the September 2021 incident. Solana also faced other outages, including one in May 2022 (lasting 7 hours), another in June 2022 (lasting 4 hours), and a major network breakdown on 6 February 2024, where a technical malfunction halted block production for almost five hours. However, Solana's development team has made several key improvements to enhance the blockchain's resilience. These upgrades include better coordination among validators, enhanced stability measures, and improvements in on-chain governance.

Solana vs Ethereum: A comparative analysis

Transaction speed

Solana has an edge over Ethereum in terms of transaction speed, processing around 200 to 400 transactions per second (TPS) on average, and it can surge to over 2,000 TPS during high demand. Ethereum currently handles around 15-30 TPS. However, Ethereum is improving its scalability through Ethereum 2.0, which aims to reach up to 100,000 TPS through sharding and other Layer 2 solutions. However, Solana’s speed still provides an immediate advantage for high-performance applications such as gaming, DeFi, and NFTs​.

Costs

Another strong advantage is the cost of transactions on Solana. Solana’s average transaction fees are as low as $0.0001 per transaction, which is extremely low compared to Ethereum, where gas fees can fluctuate between $10 and hundreds of dollars during network congestion. While Ethereum’s high fees stem from its strong security and decentralization, they remain challenging for everyday users and developers​.

Developer community

Ethereum leads with its mature and extensive developer community, backed by many decentralized applications (dApps) and DeFi protocols. It has been the go-to platform for developers since 2015, hosting around 3,000 to 4,000 dApps​. Although newer, Solana has rapidly attracted developers due to its scalability and low fees, especially in high-performance sectors like gaming and high-frequency trading. However, Ethereum’s developer ecosystem remains larger and more established​.

EVM compatibility

One of the major challenges Solana faces is its lack of Ethereum Virtual Machine (EVM) compatibility. This makes it more difficult for Ethereum developers to migrate their dApps to Solana seamlessly. Ethereum's EVM support allows developers to use the same tools and smart contract languages like Solidity, which is a key reason for its developer dominance. Solana, on the other hand, supports Rust and C, which are powerful but less familiar to Ethereum developers.
