Blocksize is a German-based DeFi infrastructure provider. We bridge the gap between the financial services industry and blockchain ecosystems. Beyond operating on Solana, our focus is contributing to the network itself: we run a validator and help keep the validator set healthy, decentralized and secure. We also authored and maintain the open-source Solana Exporter, used by validators worldwide to monitor and optimize their nodes, and we build the next layer of infrastructure — including high-performance RPC and Node Consensus Networks (NCNs) — together with the Jito Foundation, Solana Foundation and Turbin3.
