Solana (SOL)
Solana is the chain built around one bet: that a blockchain can be fast and cheap enough to feel like ordinary software. Transactions settle in seconds for fractions of a cent, which is why so much of crypto's retail activity — memecoin trading, NFT mints, payments — happens here. This hub collects MEXC Learn's Solana coverage. Start with the design if you are new: how Solana differs from Ethereum, what proof of history actually does, and why fees stay low when other chains get expensive under load. From there the coverage splits three ways. Network and technology. Proof of history is a cryptographic clock, not a consensus mechanism — it lets validators agree on the order of events without waiting on each other. Articles here cover how that works, the network's history of outages and the engineering response to them, including Firedancer, an independent validator client built to remove single-software risk, and Alpenglow, the consensus overhaul approved by validators in 2025. Ecosystem. Solana hosts one of the most active on-chain economies: decentralized exchanges, liquid staking, NFTs, and the memecoin launchpads that dominate its daily transaction counts. This track explains the mechanics behind that activity. Markets and staking. SOL staking pays out to delegators without giving up custody of the stake, and US spot Solana ETFs — several of which pass staking rewards through — began trading in late 2025. Coverage here tracks both. Every guide explains the mechanism, not just the headline.
Solana (SOL) FAQ
Both run smart contracts; the difference is what each optimises for. Ethereum prioritises decentralisation and pushes scale to Layer 2 networks. Solana prioritises raw throughput on a single layer — parallel transaction processing, sub-second block times, fees under a cent — and accepts heavier hardware requirements for validators as the cost.
A cryptographic clock. Solana validators run a continuous hash chain that timestamps events, so the network can agree on the order of transactions without validators messaging each other to establish it. It is not the consensus mechanism itself — Solana still uses proof of stake — but it is the reason blocks can be produced so quickly.
It did, repeatedly — several full outages between 2021 and early 2024, mostly triggered by transaction flooding and client bugs. The record since has improved markedly, and the structural fix is client diversity: Firedancer, a second validator implementation built independently by Jump, exists so that one software bug can no longer stop the whole network.
You delegate SOL to a validator without transferring custody — the stake stays in your control and can be undelegated after a cooldown measured in days. Rewards come from the network's issuance schedule and are shared by the validator, minus its commission. Yield moves with total stake and network activity, so check live figures rather than quoted ones.
Create an account and complete KYC verification, then fund it by card, bank transfer, P2P, or a crypto deposit. Most users buy a stablecoin such as USDT first, then trade it for SOL on the SOL/USDT spot market. From there you can hold it, withdraw to your own wallet, stake it, or move it into other products.
