What Is Solana?

Solana is one of the most-used Layer 1 blockchains, focused on high throughput, low fees, and consumer-grade application performance. It runs its own consensus, supports smart contracts directly, and is widely treated as the main scalability-first alternative to Ethereum.

The chain powers a broad mix of dApps across NFTs, DeFi, payments, and gaming, and supports a large stablecoin economy.

Solana Is a Layer 1 Blockchain

Solana is a Layer 1 blockchain: a standalone base network that handles its own transaction execution, security, and data storage. Unlike Layer 2 systems that scale by building on top of an existing chain, Solana was designed from the ground up to be fast and scalable at the base layer, with no need for separate rollups or sidechains.

• Independent network with its own consensus.
• No reliance on Ethereum or Bitcoin for security or settlement.
• Native support for smart contracts, tokens, and dApps.
• High throughput at the base layer, without needing rollups.

Solana’s chain has its own dedicated Solana network page with live metrics on Blockspot.

How Solana Works: Proof of History + Proof of Stake

Solana’s performance comes from combining two consensus ideas: Proof of History (PoH) and Proof of Stake (PoS).

Proof of History is Solana’s signature contribution. It is a cryptographic timestamping scheme that establishes the order of transactions before they reach consensus, so validators do not have to coordinate ordering from scratch. The verifiable history lets the network process transactions in parallel without losing track of sequence.

Proof of Stake handles validator selection: nodes stake SOL and are chosen to confirm transactions in proportion to their stake. Validators earn rewards for honest participation, which keeps the network secure without the energy cost of Proof of Work.

Speed, Cost, and Performance

The combined design gives Solana some of the highest throughput and lowest fees among general-purpose chains.

• Block time: Around 400 milliseconds per block.
• Live throughput: Typically 2,000 to 4,000+ transactions per second under real load.
• Theoretical ceiling: Tens of thousands of TPS in lab conditions, depending on validator hardware and network upgrades.
• Median fee: Fractions of a cent per transaction.
• Energy use: Negligible per transaction relative to Proof-of-Work chains.

The practical upshot is that Solana can support workloads that would be prohibitively expensive or slow elsewhere: micropayments, on-chain order books, real-time games, and high-frequency DeFi strategies.

The SOL Token

SOL is the native token of the Solana blockchain. It is used to pay fees, secure the network through staking, and vote on governance proposals.

• Pay fees: Every transaction and smart contract interaction is paid in SOL.
• Stake and secure: Holders delegate SOL to validators and earn a share of rewards.
• Govern: Some upgrades and parameter changes are voted on by SOL holders or stake-weighted delegates.
• Interact with apps: SOL is used directly inside DeFi, NFT, and payments apps on the network.

SOL has a disinflationary issuance schedule rather than a hard cap. New SOL is minted as staking rewards on a declining curve, while a portion of each transaction fee is burned, removing supply over time. In practice this means net supply growth is bounded and falls as the network matures, rather than being unlimited in any meaningful sense.

Solana’s Token Standard: SPL

Solana has its own token standard called SPL (Solana Program Library). It plays the same role as Ethereum’s ERC-20 for fungible tokens and ERC-721 for NFTs, but is implemented natively in the Solana runtime.

• Create and manage fungible tokens, including stablecoins and memecoins.
• Mint NFTs for art, collectibles, gaming items, and identity primitives.
• Launch new project or community tokens with minimal setup.
• Trade and swap tokens through any SPL-aware app or DEX.

Almost every asset on Solana, from USDC and USDT to memecoins, is an SPL token.

Use Cases on Solana

Solana’s speed and low fees make it usable for applications where most other Layer 1 chains struggle.

• Send value globally in seconds with near-zero fees.
• Swap tokens through DEX aggregators such as Jupiter.
• Buy and sell NFTs on marketplaces such as Magic Eden.
• Play on-chain games with real asset ownership.
• Stake SOL for yield through validators or liquid staking protocols.
• Vote in DAOs and other on-chain governance systems.
• Buy tokenised real-world assets through apps like Homebase.
• Accept USDC at checkout through Solana Pay, including in Shopify integrations.

Smart Contracts and Sealevel

Solana smart contracts are written in Rust, C, or C++ rather than Solidity, which means Ethereum contracts cannot be ported directly. The Sealevel execution engine compensates by allowing many smart contracts to execute in parallel, in contrast to Ethereum’s single-threaded EVM.

• Multiple transactions execute simultaneously when they touch different accounts.
• Apps stay responsive even when the network is under heavy load.
• Complex on-chain logic, like order books or high-frequency game state, becomes feasible.
• The execution model is fundamentally different from EVM-based chains, with its own learning curve for developers.

Real-World Metrics

Solana’s headline numbers are now anchored in real, sustained usage rather than testnet promises.

• Fee-paying accounts (all-time): Tens of millions.
• NFTs minted: Hundreds of millions.
• Median transaction fee: Roughly $0.0006.
• Active validator nodes: 2,000 to 3,000+ worldwide.
• Total transactions processed: Hundreds of billions cumulatively.

Solana Mobile: Saga and Seeker

Solana Mobile’s first device, the Saga smartphone, launched in 2023 with an integrated hardware wallet (Seed Vault), a custom dApp store free of Apple and Google restrictions, and direct support for SOL, NFTs, and Solana Pay. The Saga’s official lifecycle ended in 2025, with support wound down around October 2025.

The successor device, the Solana Seeker, is now the focus of Solana Mobile’s development effort and aims to push Web3 mobile experiences further with refined hardware and software. The Saga and Seeker together represent the longest-running attempt at a crypto-native consumer smartphone.

Decentralisation and Reliability

Solana is secured by a global set of validators that stake SOL, propose blocks, and confirm transactions. Decentralisation is lower than Ethereum’s, largely because Solana validators need more powerful hardware than a typical Ethereum node, but the validator set is geographically broad and operationally independent.

• 2,000 to 3,000+ active validator nodes worldwide.
• Validators are rewarded in newly issued SOL plus a share of transaction fees.
• Hardware requirements are a known barrier; the Solana Foundation is working to lower them.
• The chain remains censorship-resistant in practice, even if entry to running a validator is harder than on smaller chains.

Reliability has been the other long-standing critique. The network has had several full or partial outages in past years, often triggered by spam, mempool storms, or software bugs.

• A multi-hour full outage in 2022 during heavy load.
• A 5-hour outage in February 2024.
• Severe congestion during meme-coin launches in 2024 and early 2025.

Since 2024, validator clients and traffic-control tools have been substantially upgraded, and major outages have become noticeably rarer through 2025. Reliability is no longer the dominant story it once was, though it remains worth watching.

Stablecoins and Payments on Solana

Solana hosts native versions of the largest stablecoins, and is a major settlement layer for stablecoin payments.

• USDC
• USDT
• PYUSD (PayPal’s stablecoin)
• UXD

Solana Pay lets merchants accept USDC and other stablecoins at the point of sale with near-zero fees and instant settlement, including through Shopify integrations.

Developer Ecosystem

Solana has one of the most active developer communities in crypto.

• Tens of thousands of developers have participated in Solana hackathons.
• The Solana Foundation runs grants, accelerators, and educational programmes.
• Major events like Solana Breakpoint and Hacker Houses keep the community connected.
• Thousands of new on-chain programmes are deployed each month.

The combination of Rust-based development, fast execution, and low fees attracts both blockchain-native builders and experienced software engineers crossing over from traditional backends.

Solana’s strengths are clear: speed, cost, and a deep consumer-app focus. Its trade-offs in decentralisation and historical reliability remain real, but both have improved, and the chain now sits in a small group of Layer 1s that can credibly handle mainstream-scale workloads.
