How Solana works (plain English)

Proof of Stake + Proof of History (PoH): the “crypto clock”

Solana uses Proof of Stake (PoS) to select block leaders and secure the network, but it speeds up ordering with Proof of History (PoH). The current leader runs a verifiable sequence of hashes that acts like a shared clock; incoming transactions get stamped on that timeline. Because everyone can quickly verify the stamps, validators don’t need lengthy back-and-forth to agree on order. Tower BFT then finalizes blocks by voting against those PoH ticks. In practice, this drastically cuts consensus chatter and shortens time to confirmation.

Sealevel / SVM: many lanes on one highway

Most chains execute transactions one by one. Solana’s Sealevel runtime executes unrelated transactions simultaneously as long as they touch different accounts. Every transaction declares which accounts it will read/write, so the runtime can schedule non-conflicting work across CPU cores (and even GPUs for things like signature verification). Result: high throughput without splitting the chain—great for composability.

Networking for bursts: QUIC, stake-weighted QoS, Turbine, Gulf Stream

Earlier UDP-only networks were easy to flood. Solana’s node stack added QUIC (UDP-based but with flow control), plus stake-weighted QoS so well-staked peers aren’t drowned out by spam. Turbine shards blocks into small “shreds” to fan data out quickly, and Gulf Stream forwards transactions to upcoming leaders (keeping the mempool tiny and latency low).

Fees that target hot spots: priority fees & local fee markets

Solana’s fee model has a tiny base fee and an optional priority fee priced by compute. Crucially, congestion and bidding happen locally to the busy program or state range. If a hyped NFT mint is congested, priority fees rise there, your simple wallet transfer or another app remains cheap. The same can happen for hyped memecoin mints where we can see Jito fees spike in order to get transactions through quickly.

What is Solana used for?

DeFi (don’t skip this one)

Solana’s low fees and fast confirmations enable trading that feels closer to Web2. You’ll find:

• Routers/aggregators: Jupiter helps route swaps across many pools to find best execution.
  
• Liquidity & yield: Kamino and Meteora support concentrated liquidity, vaults, and automated strategies.
  
• AMMs & orderbooks: Protocols mix AMM pools with on-chain orderbooks, enabling fast swaps and more advanced strategies with minimal fee drag.
  For users, the draw is simple: more attempts per minute (edits, cancels, retries) cost pennies instead of dollars. For builders, one global state means DeFi legos compose cleanly, no cross-rollup complexity.
  

Memecoins & on-chain speculation

Memecoins produce chaotic, spiky demand, thousands of tiny buys/sells in seconds. Solana’s fast blocks, parallel runtime, and optional priority fees make that stampede survivable. You can bid a little extra (still cents) to get included faster without exploding costs chain-wide.

NFTs & creator tooling

Solana’s NFT stack led by Metaplex made mints and transfers cheap and fast. Popular drops can proceed without pricing out newcomers, and state compression lets teams issue huge collections or badges by storing most data off-chain but verifying on-chain. Cheap list/delist actions also encourage active secondary markets.

DePIN (decentralized physical infrastructure)

Projects that tie tokens to real-world activity: wireless hotspots, dashcam mapping, compute marketplaces need lots of micro-transactions. Solana’s economics (fractions of a cent per action) make device rewards and proofs practical. Networks like wireless coverage or community mapping rely on that cost profile to scale. Some examples have been parcl and get grass.

Gaming & real-time apps

Games and social apps need frequent, small state updates: inventory changes, in-match events, tipping, badging. Sub-second blocks and parallel execution keep UX snappy. Builders can combine on-chain assets (NFT items) with fast settlement for in-game markets, all on one composable L1.

Payments & commerce

With Solana Pay, merchants can accept stablecoins like USDC and settle directly to a wallet in seconds. On the user side, checkout is a scan-and-confirm flow; on the merchant side, there’s no waiting days for settlement or paying percentage fees.

Solana Fees, speed, and how to think about “priority”

• Base fee: tiny, denominated in lamports (the smallest unit of SOL).
  
• Priority fee: a small, optional tip per compute unit that improves your spot in the leader’s queue when demand spikes on a specific app.
  
• Local fee markets: that spike stays local to the busy program (e.g., a mint), while other apps remain cheap.
  Beginner tip: during a hot launch, set a modest priority fee in your wallet to improve inclusion without overpaying. You might need to set up to 0.02 sol.
  

Solana vs Ethereum

Both Solana and Ethereum are generalized smart-contract platforms, but they optimize differently.

• Scaling strategy:
  
  • Solana scales the base layer itself: one chain, parallel execution, very fast blocks, and aggressive networking optimizations.
    
  • Ethereum keeps the base layer conservative and scales via Layer-2 rollups (Optimistic and ZK). L2s inherit Ethereum security but introduce bridging and cross-rollup UX.
    
• Composability:
  
  • Solana: Everything lives on a single global state; protocols compose synchronously by default.
    
  • Ethereum: Within a single L2, composability is great; across L2s, you need bridges or shared sequencing.
    
• Fees & UX:
  
  • Solana: Fees are low on L1; priority fees are local to hotspots.
    
  • Ethereum: L1 fees fluctuate with demand; most users are expected to live on L2s for cheaper transactions.
    
• Tooling & languages:
  
  • Solana: Rust (and C/C++), Anchor framework, an accounts-first model (SVM).
    
  • Ethereum: Solidity, EVM tooling (Hardhat/Foundry), massive developer base and libraries.
    
• Decentralization profile:
  
  • Solana: Higher hardware requirements for validators and historically more stake concentration, improving over time.
    
  • Ethereum: Low barrier to run a validating node, but a significant share of validators/stake is operated via large pools and providers.
    Takeaway for beginners: If you want one chain with web-like UX and low fees for NFTs, memecoins, and fast DeFi, Solana is compelling. If you prefer EVM tooling and a modular, L2-first world, Ethereum fits well. Plenty of users and teams operate on both.
    

Staking on Solana (how it works, in short)

• What staking does: You delegate SOL to a validator to help secure the network and earn rewards. Your SOL never leaves your wallet’s control; you’re assigning vote weight, not handing over custody.
  
• How to stake: In supported wallets, pick a validator and delegate. Staked SOL activates over epochs (roughly a couple of days). You can deactivate stake to unstake; that also completes over epochs before funds are fully liquid.
  
• Rewards & commissions: Validators set a commission that’s deducted from staking rewards; choose one with strong performance and reasonable commission. Many users diversify across several validators.
  
• Risks & best practices: You’re trusting validator performance, not custody. Use reputable wallets, avoid unknown validator identities, and monitor your stake from time to time. (Advanced users can run their own validator, but hardware requirements are significant.)
  

Recent upgrades & what’s next

• QUIC & stake-weighted QoS: These live networking changes reduced packet floods, added rate limiting, and prioritized honest traffic, key ingredients behind improved reliability.
  
• Local fee markets & priority fees: Congestion is isolated to the busy app; wallets surface simple sliders so users only pay up when it matters.
  
• State compression: A technique for compressed NFTs and attestations that drastically reduces on-chain storage, useful for loyalty, tickets, and DePIN proofs.
  
• Firedancer (by Jump Crypto): A from-scratch, C/C++ validator client designed to boost throughput and, more importantly, add client diversity. If one implementation has a bug, the other can keep the network running. Firedancer’s lab demos point to significant headroom; staged mainnet roles are expected as testing completes.
  
• Runtime & developer ergonomics: Expect ongoing work on the Solana Virtual Machine (SVM) and frameworks (like Anchor) to make building easier and safer, plus incremental consensus/voting refinements that aim to cut latency further—without giving up safety.
  

Solana Risks & trade-offs (honest version)

• Past outages: 2021–2022 included several high-profile incidents tied to spam and software limits. The networking and fee-market changes above largely targeted those failure modes, and operational processes have matured since. Still, reliability is measured over years; check public status pages if you’re coordinating time-critical launches.
  
• Hardware & decentralization: High-end validator hardware raises the bar to participate and can concentrate stake among professional operators. Delegation programs and more efficient clients (like Firedancer) aim to broaden participation over time.
  
• App-layer risk: Most user losses in crypto come from app bugs, wallet compromises, or bridges, not consensus failures. Stick to reputable wallets and audited protocols; double-check addresses and approvals.
  
• Regulatory uncertainty: As with any public blockchain, token and compliance questions evolve by region. Teams often emphasize stablecoins and utility tokens to reduce friction.
  

How to get started with Solana

1. Install a wallet (e.g., Phantom, Solflare, Backpack) and back up your recovery phrase securely.
   
2. Fund a small amount of SOL for fees (even a few dollars goes a long way).
   
3. Try a simple action: send SOL to a friend, mint a low-cost NFT, or make a small swap via an aggregator.
   
4. Explore DeFi: test a swap route on Jupiter, deposit into a Kamino or Meteora pool with a tiny amount to learn the flows.
   
5. Stake SOL: delegate to one or more validators from your wallet and monitor rewards over a few epochs.
   
6. Busy day? If a mint or launch is crowded, add a modest priority fee to improve inclusion, don’t overpay.
   

Frequently asked questions

Is Solana really that fast?
Yes, sub-second block production and parallel execution make it feel “instant” in most wallets. Finality typically arrives within a few seconds.

How are fees so low and do they spike?
Base fees are tiny; during hype, priority fees rise only where demand is hot (the specific program/state), so the rest of the chain stays cheap.

Why do memecoins and NFTs gravitate to Solana?
They involve lots of small, time-sensitive transactions. Solana’s fee model, parallel runtime, and PoH-accelerated ordering keep things moving even under heavy load.

Can I use Solana for everyday payments?
Yes. With Solana-based checkouts, merchants can accept stablecoins like USDC with near-instant settlement to a wallet.

Do I need to run a node to stake?
No. Most users delegate stake from a wallet to one or more validators and can deactivate/reactivate as needed over epochs.

The bottom line

Solana’s recipe, PoH-accelerated ordering, parallel execution, smart fee markets, and hardened networking delivers a single, composable chain that feels fast enough for mainstream apps. That’s why activity spans memecoins, NFTs, DeFi (Jupiter, Kamino, Meteora), gaming, DePIN, and payments. If you’re new, start small: install a wallet, grab a little SOL, try a swap or mint, and stake. If you’re building, learn the accounts model and Sealevel patterns and you’ll see why teams say many things are “only possible on Solana.”
