Plain English

Solana is a high-throughput blockchain that competes with Ethereum for smart-contract and DeFi activity. It is known for very fast transactions and very low fees. The native currency is SOL.

How it actually works

Solana uses a hybrid proof-of-stake plus “proof-of-history” consensus that lets validators agree on transaction order without coordinating each block. The result is thousands of transactions per second at fractions of a cent. The trade-off is a smaller, more centralized validator set than Ethereum.

What it means for you

For members who need cheap, fast transactions — consumer apps, NFT trading, active DeFi — Solana is the working alternative to Ethereum. The trade-off is structural: less decentralization, more reliance on a smaller validator set.

How ARCrypto teaches this

We teach Solana custody, staking, and the practical use cases where it makes more sense than Ethereum’s higher-fee mainnet.
