Solana: A High-Performance Blockchain Platform

Anatoly Yakovenko published the Solana whitepaper titled "Solana: A New Architecture for a High-Performance Blockchain," introducing a novel proof-of-history mechanism combined with proof-of-stake to achieve high transaction throughput without sharding. The paper proposed using a verifiable delay function to timestamp transactions before they are added to blocks.

The Solana mainnet went live with the creation of its first block. The network was launched by Solana Labs, founded by Anatoly Yakovenko and Raj Gokal in San Francisco. Solana was designed to support smart contracts and decentralized applications with a theoretical throughput of over 50,000 transactions per second, positioning it as a competitor to Ethereum.

Solana Labs sold 314 million USD worth of SOL tokens to a group of investment funds led by Andreessen Horowitz and Polychain Capital. The funding round was one of the largest in the cryptocurrency industry at the time and fueled rapid development of the Solana ecosystem, including the growth of DeFi protocols and NFT marketplaces on the platform.

The Solana blockchain went offline for approximately 17 hours after a surge of transactions caused the network to fork, with different validators holding conflicting views of the network state. The outage was the first of several significant reliability incidents that raised concerns about Solana's stability and its ability to handle high transaction volumes.

SOL reached an all-time high of approximately 259.96 USD, giving Solana a market capitalization of over 74 billion USD. The price had risen by nearly 12,000% over the course of 2021, driven by a surge in NFT activity on the Solana blockchain and the platform's reputation as a faster and cheaper alternative to Ethereum for decentralized applications.

A coordinated hack compromised 9,231 Solana wallets, with attackers stealing approximately 8 million USD in SOL and other tokens. The Solana Foundation identified the exploit as originating from the Slope Finance wallet software, which inadvertently transmitted private key material to a centralized server. The incident highlighted security risks in the Solana ecosystem.

The bankruptcy of FTX and its trading arm Alameda Research severely impacted Solana, as SOL was Alameda's second-largest holding. FTX held 982 million USD in SOL tokens. The token's price dropped 40% in a single day, and by the end of 2022, Solana had lost over 50 billion USD in market capitalization since the start of the year.

The US Securities and Exchange Commission filed a lawsuit against Coinbase, alleging that SOL and twelve other cryptocurrencies failed the Howey Test and qualified as unregistered securities. Robinhood subsequently delisted SOL and other tokens named in the SEC complaint. The Solana Foundation denied that the token is a security.

Visa announced that it had added support for the Solana blockchain to send USDC stablecoin payments to merchants through payment processors Worldpay and Nuvei. The integration marked a significant enterprise adoption milestone for Solana, demonstrating its capability for real-world payment settlement with major financial infrastructure providers.

SOL reached a new all-time high of 294 USD following the launch of US President Donald Trump's official $TRUMP memecoin on the Solana blockchain. The launch caused a surge in Solana network usage and trading volume, driving SOL prices above the previous 2021 record. The milestone underscored Solana's recovery from the FTX collapse and its role in high-profile token launches.
