Solana (SOL) is a layer-1 blockchain conceived by Anatoly Yakovenko, a former Qualcomm engineer, in 2017 and launched on mainnet beta in March 2020. Its founding ambition was to solve the "blockchain trilemma"—the widely held view that no network can simultaneously achieve decentralisation, security and scalability. To do so, Solana adopted a hybrid consensus mechanism combining Proof of History (PoH) with Proof of Stake (PoS). In theory, the network can process 65,000 transactions per second at a cost of $0.002 to $0.05 per transaction. As of July 2026, SOL fluctuates in and out of the top five cryptocurrencies by market capitalisation.

Origins

Solana's beginnings were modest. Yakovenko's core insight, developed during his time at Qualcomm, was that existing blockchains were slow because every participant had to verify the sequence of transactions individually. His solution was to build what might be thought of as a giant shared clock—a mechanism that stamps every transaction with a verified timestamp the moment it occurs. This is Proof of History. The result, in theory, is a network capable of processing transactions more than 3,000 times faster than Ethereum, which handles roughly 20 per second.

When SOL launched in 2020, it traded at around $1 and attracted little attention. That changed dramatically in 2021, when the twin booms in non-fungible tokens (NFTs) and decentralised finance (DeFi) sent developers flooding onto the platform. Frustrated by Ethereum's soaring transaction fees, they found in Solana a cheaper, faster alternative. The ecosystem expanded rapidly, and SOL surged to $258 in November 2021, briefly making it the third or fourth most valuable cryptocurrency in the world. It was during this period that Solana acquired the nickname "Ethereum killer."

Then, in November 2022, came the defining catastrophe. FTX, at the time one of the world's largest cryptocurrency exchanges, collapsed into bankruptcy. Its founder, Sam Bankman-Fried, had been one of Solana's most prominent backers and investors. The fallout was devastating: projects across the Solana ecosystem imploded, and SOL tumbled to a low of $9—a fall of 96% from its peak. Many observers concluded that Solana was finished.

They were wrong. Over the course of 2023, SOL rebounded nearly tenfold. In 2024, Solana became the spiritual home of the memecoin craze—a wave of speculative, joke-themed digital tokens that proliferated on its fast, cheap network and attracted swarms of retail traders. On 18th January 2025, two days before Donald Trump's inauguration as president, he launched a Solana-based memecoin bearing his name. The frenzy that followed was extraordinary: for a single day, Solana captured 73.3% of all profits generated across the entire cryptocurrency market. SOL hit its all-time high of $295 in January 2025.

What Solana actually does

SOL is the native token of the Solana blockchain, serving three main functions: paying transaction fees, staking to help secure the network, and participating in governance decisions. The ecosystem built on top of Solana spans decentralised finance, NFTs, gaming and payments. Jupiter, a decentralised exchange (DEX), has demonstrated that real-time trading—difficult to achieve on Ethereum—is viable on Solana, and has become a flagship application for the network.

Payments infrastructure, anchored around the stablecoin USDC, has emerged as another pillar of the Solana ecosystem. In September 2023, Visa struck an agreement to settle overseas USDC payments via Solana rather than Ethereum—a significant endorsement of its potential as financial infrastructure. Google, Stripe and Discord are among the mainstream companies that have extended support to the Solana ecosystem. A spot Solana exchange-traded fund (ETF) has also been launched, marking its entry into regulated investment products.

Risks and controversies

Solana's most persistent vulnerability has been network reliability. Before 2022, it suffered multiple complete outages—a side effect of its design choice to prioritise performance over decentralisation. Running a validator node requires high-specification hardware, which raises barriers to entry and means the network is meaningfully less decentralised than Ethereum. Subsequent upgrades have substantially improved stability, but the underlying tension between speed and resilience has not disappeared.

The memecoin boom of 2024–25 proved a double-edged sword. It drove a surge in network traffic and fee revenues, but also exposed how heavily Solana's activity depended on speculative demand. As the memecoin bubble deflated, Solana entered a prolonged correction: by early 2026, SOL was trading at around $90, roughly 70% below its all-time high.

Competition from Ethereum is another variable. Ethereum's layer-2 scaling solutions have dramatically reduced transaction costs, eroding one of Solana's principal competitive advantages. The strategic question now is whether Solana can move beyond being merely a fast blockchain and establish a distinct position in payments, real-world asset tokenisation (RWA) and decentralised physical infrastructure networks (DePIN)—and whether it can do so quickly enough.

Assessment

Solana has already proved it cannot easily be killed. It survived the worst-case scenario of the FTX collapse, rebuilt its ecosystem through the memecoin era, and retains genuine advantages over Ethereum in speed and cost. Visa and Google's involvement, alongside the launch of a spot ETF, signal growing acceptance by mainstream institutions.

Yet the concerns over memecoin dependency and network stability have not been fully resolved. Institutions may route transactions through Solana, but they still tend to trust Ethereum as the primary vault for storing digital assets. Whether Solana can graduate from being a "digital playground" to genuine "digital infrastructure" will ultimately determine its long-term value.
