In April 2020, a former Qualcomm engineer named Anatoly Yakovenko launched a new blockchain called Solana. Its pitch was simple and audacious: Ethereum was too slow and too expensive, and Solana would be the alternative that scaled to millions of users with fast, cheap transactions. Where Ethereum processed about 15 transactions per second at high cost, Solana claimed to process 50,000 transactions per second at almost no cost.
The key innovation was called “Proof of History,” a novel technique that let the network agree on the order of transactions without needing to communicate about it. This removed a major bottleneck in traditional blockchains. Combined with other optimizations — parallel transaction processing, fast gossip protocols, and innovative consensus algorithms — Solana achieved unprecedented performance for a decentralized network.
Solana’s launch was well-timed. DeFi was exploding on Ethereum in 2020, and gas fees were making small transactions impossible. Users were desperate for a cheaper alternative. Solana offered it, and developers flocked to build on the new platform. Within months, Solana had its own DeFi ecosystem, NFT marketplaces, and games — all with transaction costs measured in fractions of a cent.
Solana’s SOL token exploded in value during the 2021 bull market. From launch price of about $1, SOL reached over $250 at its peak, giving Solana a market cap of over $75 billion. Early investors who had bought SOL during its 2020 IEO saw returns of 100x or more. Solana became the most credible “Ethereum killer” — a title many projects had claimed but few had delivered on.
But Solana had its problems. The network experienced several major outages during 2021-2022, sometimes going offline for hours. Critics argued that Solana had sacrificed decentralization for speed — the network had relatively few validators and required expensive hardware to run. The FTX collapse in late 2022 hit Solana especially hard because FTX had been a major SOL holder. Yet Solana survived. By 2024, it had become one of the most actively used blockchains in the world, home to a thriving NFT and DeFi ecosystem, and a serious rival to Ethereum.
