The DoubleZero Foundation has launched its mainnet beta, which is a dedicated network designed to accelerate blockchain validator communication by using private fiber routing instead of the public internet. Co-founder Austin Federa emphasized that this move can reduce latency, enhance security, and improve user experience. With support from companies like Jump Crypto and Galaxy, nearly 21% of staked SOL is connected. After the SEC issued a no-action letter, DoubleZero raised $28 million at a valuation of $400 million and accessed and rewarded using its native token 2Z on Solana. The project plans to expand to other blockchains.
