What is Solana?

Solana was created as a scalable solution to run decentralized apps and facilitate the use of smart contracts. It was named after Solana Beach, California, the beach town where the founders spent time and came up with the idea for the blockchain. 

How does Solana work?

Solana operates using a combination of Proof-of-Stake and Proof-of-History consensus mechanisms. Anatoly Yakovenko, one of Solana’s founders, authored the 2017 whitepaper that first introduced the concept of Proof-of-History, which allows Solana nodes to quickly add new blocks to the blockchain. “Solana does this by inserting data into the sequence by appending the hash of the data of the previously generated states. The state, input data, and count are all published — and impossible to recreate or create alternate versions of. This sets up an upper bound on time — and because Proof of History can reference previous hashes, there is also a lower bound of time,” explains the chain’s documentation. So while this won’t give you the exact time in clock format that actions occurred, it will tell you the order in which the actions occurred.

Combined with Proof-of-Stake, which uses validators to determine a block’s validity and add it to the blockchain, Solana can minimize and better manage its energy output. The average Solana transaction uses approximately the amount of energy as a handful of Google searches, and its transaction fees can be as low as a fraction of a US cent.

Solana uses both consensus mechanisms to ensure that it can remain decentralized, scalable, and secure. Solana’s method is one approach for scaling the number of transactions processed per second. 

What are Solana’s main uses?

DApps on Solana

‍Decentralized apps (or DApps) are blockchain-integrated websites that require you to connect and approve all transactions with your wallet signature. Solana is a popular blockchain for dApps because of its speed and scalability. 

DeFi on Solana

Decentralized Finance, often shortened to “DeFi,” is the term used to describe all financial services that operate on blockchain technology. Common services include earning interest, borrowing, lending, and trading. DeFi enables trustless, permissionless, and fast transactions.  Solana's DeFi ecosystem has grown substantially since its early days, and now supports a wide range of applications.

What are Solana NFTs?

Solana NFTs are non-fungible tokens (NFTs) minted onto the Solana blockchain. NFTs are unique, digital items with blockchain-managed ownership, from digital art and collectibles to crypto domain names and ownership records for physical assets.Solana has become a popular blockchain for NFT projects because of its fast speed, low gas fees, and vibrant community.‍

What are Solana tokens? 

SOL is the native token of the Solana blockchain, and it covers the network fee for actions on Solana. Beyond SOL, the network supports a wide range of other tokens built using its token standard, from stablecoins such as USDC on Solana to tokens created by projects and communities. Using OpenSea, you can swap tokens on Solana directly in your wallet.

How do I buy and use Solana?

How do I buy SOL and Solana NFTs?

To purchase Solana, you will need a Solana-compatible wallet, like Phantom or Solflare. This wallet will be your key for purchasing, selling, or storing cryptocurrency or Solana NFTs. You can find a full explainer here. 

How do I interact with Solana NFTs and tokens?

Once you have access to your wallet, there are two things you can do using OpenSea: swap tokens on Solana, and buy and sell Solana NFTs from a selected group of collections. You can also transfer NFTs or view a collection.
