DoubleZero, which coordinates a global fiber optic cable network to boost blockchain performance, raised $28M in a token round, sources say at a $400M valuation

Context & Ripple Effects
DoubleZero’s financing sits alongside a broader set of infrastructure-focused crypto fundraises in the coverage: Zerohash’s $104M round for trading and stablecoin infrastructure and Digital Asset’s reported financing for a privacy-focused public blockchain both show capital targeting the layers beneath end-user crypto products.
What distinguishes DoubleZero is its focus on the network path itself. The reported valuation gives investors a discrete benchmark for a company positioning fiber connectivity as a lever for blockchain performance, rather than building a blockchain or business-facing service directly.
First-order effects
- DoubleZero gains $28M of financing and a reported $400M valuation benchmark, strengthening its ability to pursue its fiber-network coordination strategy.
- The token-round structure places the company’s financing in the crypto-native capital market, while the report provides no detail on token terms, buyers, or use of proceeds.
Second-order effects
- Other blockchain-infrastructure companies will be compared not only on protocol features or service integrations but also on whether they can demonstrate performance advantages from underlying network infrastructure.
- The round broadens the set of infrastructure layers competing for crypto capital: alongside Zero Hash’s earlier Series D for embedded crypto services, connectivity becomes another investable bottleneck in the stack.
Third-order effects
- If such financings continue, blockchain infrastructure investment may become more vertically segmented, spanning connectivity, privacy-oriented networks, proof systems, and business-facing rails rather than concentrating only on chain developers.
- That segmentation could make performance and network access more strategic differentiators for blockchain operators, though the corpus does not establish whether DoubleZero’s approach will achieve broad adoption.
The trend: Crypto infrastructure funding is extending downward into specialized network substrate as investors seek performance gains beyond the blockchain protocol layer.
