What is Solana (SOL)?

Executive Summary

Solana is a blockchain network engineered for rapid, high-throughput transactions, aiming to accelerate mainstream adoption of cryptocurrencies and blockchain technology. It incorporates multiple speed optimizations, including Proof of History (PoH) and parallel transaction execution. Users pay transaction fees and interact with smart contracts using SOL, Solana’s native cryptocurrency.

Introduction

Scalability is a fundamental challenge in blockchain technology. As networks expand, they frequently face critical limitations in transaction throughput and confirmation latency. Solana was built to overcome these barriers without sacrificing security or decentralization.

Established in 2017 by Anatoly Yakovenko of Solana Labs, Solana leverages a novel transaction verification method. Unlike Bitcoin, Ethereum, and other leading projects that struggle with slow transaction speeds, high fees, and intensive energy requirements, Solana employs technical innovations—such as the PoH consensus mechanism and parallelization—to efficiently handle thousands of transactions per second (TPS).

How Does Solana Work?

Solana is a third-generation Proof-of-Stake (PoS) blockchain, featuring several proprietary innovations that deliver high throughput, fast transactions, and low fees. Key technologies include:

Proof of History (PoH): A time-verification method that eliminates the need for conventional timestamps, enabling validators to efficiently confirm transaction order.

Parallelization: Processes multiple transactions simultaneously, dramatically boosting network capacity.

Tower Byzantine Fault Tolerance (BFT): An optimized, practical BFT implementation for PoH, ensuring robust validator consensus.

Turbine: A mass data transfer protocol that streamlines network-wide data distribution.

Gulf Stream: A transaction propagation protocol without a mempool, reducing congestion and accelerating processing.

Sealevel: An execution engine supporting parallel smart contract execution, significantly enhancing computational throughput.

Pipelining: A transaction processing unit that accelerates authentication and data flow.

Cloudbreak: A horizontally scalable account database, enabling network expansion without performance loss.

Together, these features create a high-performance Solana network with 400-millisecond block times and the ability to process thousands of transactions per second. For comparison, Bitcoin’s block time is about 10 minutes, while Ethereum’s averages around 15 seconds.

SOL holders can stake their tokens in Solana’s PoS consensus model. Using a compatible crypto wallet, users delegate tokens to validators responsible for processing transactions. Validators share a portion of rewards with those who stake tokens in support, incentivizing both validators and delegators to operate in the network’s best interest.

What Makes Solana Unique?

Solana is committed to delivering affordable, diverse, and widely accessible transactions. Its breakthrough innovations set it apart from other blockchain platforms.

Proof of History

Accurately recording transaction order is vital in crypto. Bitcoin structures transactions into blocks with unique timestamps, requiring each node to validate blocks through network consensus—an approach that increases validation latency. Solana instead developed Proof of History (PoH).

On Solana, all events and transactions pass through the SHA256 hash function, generating unique, unpredictable outputs. Each transaction’s result serves as the input for the next hash, embedding transaction order directly into the hash output.

This process forms a seamless chain of hashed transactions, establishing a transparent and verifiable transaction order. Validators can add transactions to blocks without conventional timestamps, and the hashing process itself provides a measure of elapsed time.

By chaining transactions in hashes, validators transmit and process less data per block. Using the latest hashed state significantly accelerates block confirmation.

Crucially, PoH is not a consensus protocol but a mechanism that shortens transaction order confirmation times. Combined with proof-of-stake, it enables faster validator selection and more efficient network operation.

Extremely Low Fees

Solana’s average transaction fee is only $0.00025, dramatically lowering barriers to Web3 adoption. In contrast, gas fees on other chains often add substantial costs to transactions.

Energy Efficiency

Solana’s design allows nodes to validate transactions quickly and with minimal resources. Unlike proof-of-work networks, Solana does not require mining, making it one of the most energy-efficient blockchains.

The Solana Foundation regularly publishes independent audits of Solana’s energy footprint, comparing it to other blockchain projects. Recent benchmarks show Solana’s per-transaction energy consumption is far lower than blockchains that rely on proof-of-work.

What Is SOL?

SOL is Solana’s native utility token, burned through a deflationary model. Users require SOL to pay transaction fees for transfers or smart contract interactions. SOL holders can act as network validators, directly participating in blockchain security and governance. Like Ethereum, Solana supports smart contracts and decentralized project development.

SOL follows the SPL protocol (Solana Program Library); SPL is Solana’s token standard, similar to Ethereum’s ERC-20. SOL’s two primary functions are:

1. Transaction Fee Payment: Users pay fees to use the network or interact with smart contracts.
2. Staking Participation: SOL holders stake tokens in the Proof of Stake consensus model and earn rewards for supporting the network.

Decentralized applications (DApps) built on Solana continually expand SOL’s utility and ecosystem through new use cases and SPL-standard tokens.

Solana Ecosystem

Since mainnet launch, Solana’s ecosystem has grown exponentially, attracting developers, projects, and users worldwide. It is now one of the most active blockchains.

Major traditional companies have integrated Solana, demonstrating rising adoption. Examples include Discord’s Solana Wallet profile linking and ASICS’s use of Solana Pay for limited-edition footwear sales.

Solana’s speed and throughput make it the go-to network for innovative Web3 applications:

NFTs: Fast transactions and low fees have built a vibrant NFT community on Solana, with millions of NFTs minted and support from top platforms. Leading Solana NFT projects include Degenerate Ape Academy, Okay Bears, and Solana Monkey Business, all widely recognized in crypto circles.

Payments: Solana Pay enables frictionless, permissionless payments that settle in seconds, attracting interest from established payment providers seeking crypto integrations.

Gaming: Solana hosts blockchain games that capitalize on speed and low fees to create seamless gaming experiences, making it a favored platform for game developers.

DeFi: Solana’s rapid transactions are ideal for decentralized finance. Its DeFi projects have secured significant funding for innovative protocol development. Notable examples include OpenBook, a community-managed order book, and Jupiter Aggregator for token swaps.

DAO: Solana’s infrastructure supports the growth of decentralized autonomous organizations, enabling transparent governance and collaborative decision-making among project participants.

Mobile: With Saga, the first smartphone powered by Solana Mobile Stack, Solana leads in developing crypto-first mobile solutions, opening new doors for widespread Web3 adoption.

Future Outlook

The Solana community and Solana Foundation have announced a range of upcoming projects and initiatives:

Firedancer: Jump Crypto is building a new open-source core Solana validator client with enhanced performance, designed to further scale the network.

Mobile Expansion: Solana-integrated devices are expected to reach the general public. Solana Mobile is also developing the Solana DApp Store, a decentralized app marketplace for Web3, streamlining user access.

Network Upgrades: Ongoing enhancements—including communication protocol improvements, upgraded quality of service, and refined fee markets—are driving Solana’s continuous evolution, with project leaders presenting a clear long-term vision.

Summary

Since inception, Solana has matured into a robust, dynamic blockchain ecosystem.
