What Is Solana? A Beginner's Guide

Solana exists because a radio engineer got annoyed at how blockchains spend their time. Anatoly Yakovenko had put in years at Qualcomm, where a network that argues about clock time is a network that drops your call, and when he looked at crypto he found chains burning most of their effort on exactly that argument: what happened when. The whitepaper he published in November 2017 proposed a fix almost rude in its plainness: give the chain a clock.

Out of it came the blockchain that made speed its entire personality. This explainer covers the fast parts, the cheap parts, and the days it stopped dead, because there have been some. Not financial advice.

The clock, briefly

Every blockchain has to put transactions in order, and most do it by committee. Bitcoin settles the argument roughly every ten minutes, Ethereum roughly every 12 seconds, and in both cases ordering is the thing the whole network stops to agree on.

Yakovenko's proof of history runs a cryptographic stopwatch underneath instead. Each tick is a hash of the tick before it, so the sequence proves itself, and by the time validators vote (ordinary proof of stake, staked SOL, nothing exotic) the order is already settled. That one trick buys most of the speed: blocks arrive roughly every 400 milliseconds.

The word "beta" has hung off the network's name since mainnet went live on 16 March 2020, and six years on it is still there. Supporters read that as engineering humility, critics as a disclaimer with excellent lawyers.

Cheap enough to stop thinking about

The base fee is 5,000 lamports per signature. A lamport, named for the computer scientist Leslie Lamport, is a billionth of a SOL, so the arithmetic lands at 0.000005 SOL per transaction. Small change does not cover it, this is change too small to have a coin.

Throughput runs into the thousands of transactions per second in live traffic, on an ordinary day, visible on any Solana block explorer. Ethereum redesigned its fee market in August 2021 with EIP-1559 and fees there still float with demand. Solana's stay flat and tiny, with an optional tip for jumping the queue when things get busy.

Fees like that change what people bother building. Tokens here follow the SPL standard, the local equivalent of Ethereum's ERC-20, and the big dollar stablecoins issue on the chain too, which makes a five-dollar transfer costing a fraction of a cent actually make sense. It also, less grandly, made Solana the natural home of NFT mints, trading bots and wave upon wave of memecoins. When trying costs nothing, everything gets tried.

Solana Pay, a protocol for paying merchants straight from a wallet, arrived in February 2022 and has moved slower than its press releases promised. Most crypto payment schemes have, and that is worth saying plainly.

The stopped-clock days

Now the section the fan posts skip.

On 14 September 2021, bots stampeding a token launch shoved load to around 400,000 transactions per second and the network stopped producing blocks, entirely. It stayed down for roughly 17 hours while validators organised a coordinated restart, which for a chain whose whole pitch is speed is about the worst available headline.

Nor was it a one-off: halts kept coming through February 2024, the last of them costing about five hours, and every restart needed validators to patch and relaunch together. The engineering responses were real rather than cosmetic: new networking code, fee mechanics that price out spam, and a second, independently built validator client in the works. At the time of writing, there has been no full outage since that February 2024 stop.

Users mostly stayed through all of it, partly because the fixes held and partly because nothing else ran this fast at this price. Cheap and fast forgives a lot, but it should not forgive everything, so weigh the record yourself rather than taking either camp's word for it.

The FTX years

Solana's other scar has nothing to do with software. FTX and its trading arm Alameda were among SOL's biggest holders and loudest cheerleaders, so when FTX froze withdrawals on 8 November 2022 and collapsed within the week, the coin went down with the ship: from an all-time high near $260 in November 2021 to under $10 by December 2022. A fall of more than 95 per cent, driven mostly by who owned the thing rather than by anything the software did that month.

By November 2024 it traded above $200 again. Neither number tells you where the price goes next. Together they tell you how violently sentiment can swing around a coin whose technology barely changed in between, which is the actual lesson worth keeping.

Buying SOL without donating it to a dropdown

The purchase is the easy bit, handled by an on-ramp that turns ordinary money into crypto: Banxa has run that plumbing since 2014, with 100-plus payment methods across 100-plus countries, and in the markets it serves the flow is short. Pick SOL and an amount, paste your wallet address, then pay: cards run roughly 3 to 5 per cent all-in with coins typically landing within about ten minutes of approval, bank transfers cost nearer 1 per cent and dawdle. Clear KYC the first time, and the quoted price locks for roughly 3 minutes, so the rate you accept is the rate you get even if the market twitches while you type.

The mistake that actually costs people is the network menu. A Solana address is a run of 32 to 44 characters with no 0x at the front, and it is not an Ethereum address, however similar the vibes. Withdrawing SOL from anywhere means picking the Solana network, every time. Coins sent down the wrong rail usually stay lost, and no speed record helps you then.

The last call is custody: leave coins on a platform and you hold a claim on a business, move them to a wallet whose keys you hold, self-custody, and the homework becomes yours. Either way, size the purchase to survive a bad week. This chain is fast, absurdly cheap, and has shown everyone, twice, in public, exactly what its bad weeks look like.
