Aztec Network, which is developing an “encrypted version of Ethereum”, raised a $100M Series B led by a16z and plans a testnet within 12 months

Context & Ripple Effects
Aztec Network's $100M Series B is the largest bet yet in a16z's running portfolio of privacy infrastructure: the firm led Nym Technologies' $13M Series A for its network-level mixnet just over a year earlier, and has repeatedly backed alternative Layer 1s, including Aptos' $200M raise built by ex-Meta Diem engineers.
The timing matters because Ethereum itself is under pressure — down more than 21% in a week amid the broader selloff, with coverage describing investor and developer interest drifting away. An encrypted version of Ethereum, funded independently of the Ethereum Foundation, positions privacy as the differentiator rather than an add-on.
First-order effects
- Aztec gains a war chest sized roughly ten times Nym's Series A to build toward its testnet within 12 months, while a16z extends its privacy-stack thesis from network-level mixing to a full encrypted smart-contract chain.
Second-order effects
- Other public chains face pressure to treat privacy as a core feature rather than a niche: the pattern later shows up in Digital Asset's $355M raise for Canton Network, a public blockchain with privacy features that included $100M from a16z crypto.
- For Ethereum, a well-funded encrypted fork cuts both ways — it validates demand for Ethereum-style programmability while giving developers defecting during the interest slump a privacy-native destination.
Third-order effects
- If the funding cadence holds, privacy shifts from optional protocol feature to table stakes for public blockchains, with a small set of repeat backers like a16z effectively deciding which privacy architectures reach production.
The trend: Venture capital is consolidating behind privacy-enabled blockchain infrastructure even through the downturn, turning encryption from an Ethereum add-on into a competing chain's headline pitch.
