What blockchain is Star Atlas building on?

Star Atlas is built on the Solana blockchain.

Star Atlas is built on the Solana blockchain which is the protocol for building out massively multiplayer and immersive metaverse projects. The Solana protocol provides for an extensive serverless and secure gameplay experience.

NFTs (Non-Fungible Tokens) can be secured and traded within the metaverse itself, thus replicating the idea of an economy of real-world assets and ownership from Earth itself.

Currently, Solana's TPS (Transaction-Per-Second) rate is about 65,000. It might even increase as the network keeps developing. Solana allows real-time recording of multiple interactions between assets in the gameplay.
