What is Solana (SOL)? Is It the Fastest Blockchain?

What is Solana (SOL)? 

Solana is an open-source, public blockchain designed for speed and efficiency. The network supports smart contracts for various decentralized applications (dApps) and non-fungible tokens (NFTs). Since its inception, Solana’s rapid growth has positioned it as a top competitor to other leading programmable blockchains like Cardano and Ethereum.

Solana is powered by its native cryptocurrency SOL, which serves two primary functions:

• Paying for transactions on the network
• Providing network security through staking

Who Founded Solana? 

Understanding what is Solana requires knowing its beginnings. Solana was co-founded by Anatoly Yakovenko and Raj Gokal in 2017. Anatoly currently serves as the CEO of Solana Labs, while Raj Gokal holds the position of Chief Operations Officer.

Anatoly Yakovenko’s background in system design directly influenced Solana’s creation. His objective was to leverage this expertise to develop a new blockchain platform capable of significantly faster processing speeds than existing alternatives.

How Does Solana (SOL) Work? 

Solana was specifically developed to solve the persistent challenges of scalability and speed that plague many blockchains. What makes Solana unique is its hybrid protocol that combines two distinct consensus mechanisms:

1. Proof of Stake (PoS) – A consensus mechanism that selects validators based on the number of crypto tokens they’ve pledged (staked) to the blockchain. Validators earn rewards when they successfully add new transaction blocks to the blockchain.
2. Proof of History (PoH) – A unique algorithm exclusive to Solana that verifies both the order of blockchain transactions and the time between them. Transaction timestamps are embedded directly into the blockchain, eliminating the need for validator nodes to communicate to confirm transaction times.

This hybrid approach, particularly the Proof of History protocol, is the primary reason for Solana’s exceptional speed. By optimizing the transaction process and reducing validators’ workload, Solana enables significantly faster processing times compared to traditional blockchains.

According to a 2025 report by Messari Research, Solana consistently processes transactions 200-400 times faster than Ethereum, while maintaining lower transaction costs.

Key Features of Solana: What Makes It Different

Understanding what is Solana at a technical level means exploring its unique features. The Solana protocol incorporates several innovative technologies:

1. Turbine: Optimized Block Propagation

Turbine is a block propagation protocol that divides data into smaller increments, simplifying data transfer between nodes.

The blockchain nodes in Solana are segmented into small packets to facilitate easier transactions without experiencing bandwidth or validation problems. This approach enables faster transaction settlement.

2. Gulfstream: Eliminating Transaction Bottlenecks

Gulfstream is a Mempool-less transaction forwarding protocol that pushes transaction caching to the edge of the network. In simple terms, Gulfstream eliminates the need for a Mempool—a waiting area where unprocessed transactions queue.

By removing this waiting time, Solana can manage a memory pool size of 100,000. The network forwards transactions to validators before adding new ones, reducing verification time. This also enables:

• Faster leader switching
• Reduced memory pressure on validators
• No unconfirmed transactions remaining in the blockchain

Through Gulfstream, Solana achieves approximately 65,000 transactions per second (tps) as of 2025.

3. Sealevel: Parallel Smart Contract Processing

Sealevel is a hyper-parallelized transaction engine allowing different smart contracts to run simultaneously. It scales horizontally across SSDs and GPUs.

The ability to process multiple contracts concurrently makes the Solana network both cost-efficient and remarkably fast.

4. Archivers: Distributed Data Storage

Archivers are network nodes in Solana’s blockchain used by validators to delegate data storage. This offloads data from validators to the Archivers.

While not participating in consensus meetings, Archivers undergo frequent routine checks to verify they store appropriate network data. This happens by archiving small state sections, with the state’s history being erasure-coded and fragmented.

5. Pipelining: Optimized Transaction Processing

Pipelining assigns input data streams to specialized hardware components. It functions as a transaction processing unit for validation optimization.

Solana’s pipeline system uses multiple sequential steps to process data input streams, with each step assigned to dedicated hardware. Using specialized hardware for different steps accelerates transaction information validation and facilitates easy replication across network nodes.

6. Cloudbreak: Enhanced Scalability

Cloudbreak is a horizontal scaling method that increases Solana’s scalability. It organizes a database capable of accurately reading and writing transaction input while establishing connections between software and hardware.

7. Tower Byzantine Fault Tolerance Algorithm (BFT)

The BFT algorithm supports failing nodes to keep them operational—essentially acting as a safety shield for Solana. If a node experiences disruption or failure, BFT ensures other functioning nodes remain unaffected.

Tower BFT uses Proof of History as a cryptographic clock, achieving consensus without requiring communication between nodes.

Limitations of Solana (SOL): Understanding the Challenges

While Solana offers numerous advantages, it’s important to understand its weaknesses when evaluating what is Solana as an investment:

A significant concern in the Solana ecosystem is its centralization. Approximately half of the token supply is owned by insiders and venture capitalist firms. Additionally, only around 19 nodes control over one-third of the cumulative stake, meaning a third of validated transactions are processed by just 19 nodes.

The high requirements for validators—both in SOL holdings and hardware specifications—limit participation. This restriction has resulted in fewer users willing to validate transactions.

Solana has also faced criticism for network stability issues. In late 2021, the network experienced a 17-hour outage due to resource exhaustion, and smaller outages have occurred periodically since then. According to a 2025 Blockchain Reliability Report by DappRadar, Solana has improved stability but still ranks below Ethereum in terms of network uptime.

Questions about the transparency of the network regarding total circulating token supply have also emerged. The class action lawsuit filed against the network in July 2022, which alleged Solana was an unregistered security, further eroded user confidence.

Despite these challenges, developers and projects like Raydium and Solstarter continue joining the Solana network, attracted by its speed and low transaction costs.

How is Solana (SOL) Created? Understanding Token Generation

Solana is created through its unique Proof of Stake and Proof of History hybrid protocol. Selected stakers (validators) validate transactions by identifying the correct order of events and transactions on the network.

Unlike Bitcoin, which uses a Proof of Work consensus requiring competitive validation processes, Solana isn’t created through conventional mining.

Can You Mine Solana (SOL)?

Solana cannot be mined traditionally since it uses a Proof of Stake and Proof of History hybrid consensus mechanism. However, the Solana community can support the network and earn rewards in two ways:

1. Staking SOL

With staking, you can pledge Solana coins you own to a validator in exchange for rewards. A Solana validator typically offers rewards of approximately 6-8% per year for staking your coins to help confirm transactions on the network.

2. Running a Validator Node

Users can run a powered server in a data center to verify transactions on Solana. Validators earn commissions on rewards generated by individuals who stake coins with them. However, becoming a validator requires significant financial investment, limiting widespread participation.

Which Blockchain Does Solana Use?

Solana uses its own proprietary blockchain. This blockchain employs a hybrid of Proof of History and Proof of Stake consensus mechanisms, distinguishing it from early cryptocurrencies like Bitcoin that use Proof of Work algorithms to validate blocks.

How to Use Solana (SOL): Practical Applications

SOL is the native token of the Solana ecosystem and can be used in several ways:

• Transaction fees: Used to pay for transaction costs within the ecosystem, including fees for using smart contracts
• Staking rewards: SOL can be staked to earn passive income through staking rewards
• Network operation: Tokens pass to nodes within the Solana cluster in exchange for running on-chain programs and validating outputs
