Aztec, a layer-2 rollup focused on privacy, shared Thursday that its testnet has finally gone live.
The announcement comes as a wave of new privacy-focused solutions begins to capture the interests of large institutions that need confidentiality with large transaction batches.
The team behind Aztec said that they have been working on the product for over 8 years, bringing the cutting-edge technology one step closer to the mainnet.
Aztec differs from other zero-knowledge rollups because it is focused on helping applications and users preserve their private details by incorporating encryption on the protocol level.
“All of the secret information that you want to keep encrypted, it’s posted on our blockchain in an encrypted form,” said Zac Williamson, the co-founder of the Aztec Network, to CoinDesk.
Layer-2 networks have appeared en masse in the Ethereum space over the past few years, and are seen as a faster and cheaper alternative to transacting on the Ethereum protocol. But Aztec will have to give up elements of that in order to preserve its mission of being privacy-preserving as well as decentralized.
“A fully private transaction will have more data associated with it, because everything is encrypted. Which means that you’ve required more resources, therefore you cannot scale as much,” Williamson said. “And so we are fine with that. Aztec’s unique value proposition is not scaling. We do a little bit of that, [because] we are a layer 2, but we never need to be as cheap as other layer 2s.”
Institutions have long sought privacy-preserving tools since they are key to handling sensitive transaction data for public ledgers. Aztec raised $100 million in a series B in 2022, led by Paradigm, when conversations around blockchain privacy started to take off.
Recently, privacy-preserving tools are re-emerging as key to the industry as big institutions begin to come on-chain. On Tuesday, privacy solution Miden said it had raised $25 million in seed fundingfrom a16z.
