What is Solana (SOL)

Solana is a high-performance Layer 1 blockchain designed to scale to thousands of transactions per second without sacrificing decentralisation through traditional techniques. Founded by Anatoly Yakovenko (a former Qualcomm engineer) and launched in March 2020, Solana introduced a novel consensus innovation called Proof of History that enables unprecedented throughput while maintaining relatively decentralised validator participation.

PROOF OF HISTORY: SOLANA'S KEY INNOVATION

Most blockchains require validators to communicate extensively to agree on the time and order of events consuming bandwidth and limiting throughput. Proof of History (PoH) is a cryptographic clock that creates a historical record proving events occurred at specific times: a sequence of SHA-256 hash operations where each output becomes the next input, creating a verifiable timeline. Validators can prove that transactions occurred in a specific order and at specific times without requiring synchronous communication enabling parallel transaction processing and dramatically higher throughput.

PERFORMANCE CHARACTERISTICS

Theoretical throughput: 65,000 TPS (real-world sustained: 2,000-4,000 TPS with recent upgrades pushing higher). Transaction finality: 400 milliseconds. Transaction fees: approximately $0.00025 per transaction. These characteristics make Solana practical for high-frequency applications, gaming, DeFi, payments, and consumer NFTs that would be economically unviable on Ethereum mainnet.

SOLANA'S ECOSYSTEM

DeFi: Jupiter (DEX aggregator, one of the highest-volume in crypto), Raydium, Orca (DEXs), Kamino, Marginfi (lending).
NFTs: Magic Eden (leading marketplace), Tensor (professional traders).
Consumer Apps: Dialect (on-chain messaging), DRiP (NFT distribution).
Memecoins: Solana became the dominant memecoin chain in 2024 (BONK, WIF, POPCAT).

THE FTX CRISIS AND RECOVERY

Solana was deeply associated with FTX and Sam Bankman-Fried FTX had invested heavily in Solana early and SBF was a prominent advocate. FTX's November 2022 collapse caused SOL to crash from $38 to under $10. Billions in FTX-held SOL were expected to flood the market. Despite widespread predictions of Solana's failure, the ecosystem rebuilt through 2023-2024, with SOL recovering to $200+ and becoming one of the most active DeFi and consumer crypto chains.

Terms in addition to the Solana (SOL)

Blockchain

A blockchain is a subset of a distributed database. The Bitcoin inventors originally prototyped the system in 2008. This modern database is made up of separate blocks that are connected together in a chronological chain. Blockchains may be used to store a wide range of data types. It has mostly been utilized as a public ledger for bitcoin transactions to date. A peer-to-peer network comprised of independent nodes uses a consensus process to ensure the blockchain's security and legitimacy. Each node in the network keeps a public and immutable copy of the data.

2 Factor Authentication (2FA)

2 Factor Authentication is a security measure with two layers. It is used by the majority of cryptocurrency exchanges. To log in, you must provide not only a password, but also a code obtained, for example, from the Google authenticator.

Airdrop

An airdrop is a method of distributing coins. End users can typically obtain coins for free or in exchange for doing a small task, such as subscribing to a newsletter, sending a tweet, or inviting others via a personal affiliate link. Cryptocurrency airdrops — the act of depositing cryptocurrency into public crypto wallets — are utilized as a marketing, liquidity creation, and network bootstrapping technique for many different types of blockchain initiatives.

Altcoin

Altcoin - "alternative coin" - is any kind of digital currency other than Bitcoin. Since the launch of Bitcoin, the world's first digital currency, many altcoins (as well as supporting blockchains) have been created. Altcoin digital currencies share many similarities to Bitcoin, but consistently and have significant differences. There are about 20,000 altcoins, and this number is expected to grow significantly in the coming years. Altcoins often develop Bitcoin features. Ethereum, currently the most widely used blockchain, supports digital contracts and separate applications where Bitcoin does not. Altcoins are also often created to cater to the needs of different users. The Litecoin blockchain, for example, can process payments quarterly for the duration of Bitcoin.

Cold Storage

Cold storage is the way to store cryptocurrency offline. The word refers to the use of offline wallets that are not connected to the internet. Cold storage is the most secure way to keep cryptocurrencies since an offline currency becomes less likely to be hacked and stolen. Paper wallets, printed renditions of private keys, and offline hardware and software wallets are all examples of cold storage.
