According to online reports, people familiar with the matter revealed that the startup DoubleZero Foundation has raised US$28 million at a valuation of US$400 million, led by Dragonfly and Multicoin Capital. The DoubleZero Foundation is currently looking for "strategic partners" to seek more strategic financing at a valuation of US$600 million, which has not yet ended. According to reports, DoubleZero is building a "new type of Internet" to improve blockchain performance. Its vision is to build a global network of private optical cables and then use these optical cables to enable blockchain to transmit data more efficiently than on the public Internet. The project is seen as a key technology for Solana's ambitious plan to process 1 million transactions per second. DoubleZero is opening up its licensing test network to Solana verifiers and RPC, and plans to gradually expand to other chains. Its optical cable network is connected to dedicated lines operated by Jump Crypto, RockawayX, Distributed Global, Latitude and Terraswitch and is accepting more contributors.
