Which blockchain's native coin has the ticker SOL?

The blockchain whose native coin has the ticker SOL is Solana.

Solana is a public blockchain platform designed for smart contracts, decentralized applications, and high-throughput transactions. SOL is the network’s native cryptocurrency: users can use it to pay transaction fees, transfer value, and participate in the platform’s proof-of-stake consensus system. Solana Labs launched the network in March 2020.

The project was founded by Anatoly Yakovenko and Raj Gokal, and its design emphasizes speed and relatively low transaction costs. Solana became especially prominent during the 2021 boom in non-fungible tokens and decentralized applications, when developers and users sought alternatives to congested networks.

The names are easy to confuse because “Solana” identifies the blockchain and ecosystem, while “SOL” identifies the tradable asset. SOL is not the ticker for Algorand, Polkadot, or Avalanche; those networks use ALGO, DOT, and AVAX respectively. Solana uses proof of stake alongside a timing technique called proof of history, intended to help coordinate transaction ordering. The network has also experienced notable outages, a reminder that high throughput does not eliminate reliability challenges.
