Blockport

Blockport is a staking and infrastructure provider focused on Solana, formerly known as Zeta Node. Its core business is running high-performance validator nodes without an extra fee charged to delegators, improving realized returns through bare-metal deployment and MEV optimization; the nodes have run on mainnet since 2022, with uptime and commission published so delegators can compare before deciding.

Beyond validation it offers RPC nodes and developer-facing interfaces that wallets, trading front ends, and analytics tools can connect to, reducing the operational burden of running nodes in-house. It serves both institutions and individual delegators, and public materials list Jito, Raydium, and Edgevana as partners. The team also takes part in testing and building Solana clients and ecosystem tooling, feeding problems seen on the node side back into infrastructure improvements.
