OP Labs launched a privacy-focused product on Tuesday to attract more enterprises to the Ethereum ecosystem, starting with OP Mainnet, the layer-2 scaling network it created.
The network, previously known as Optimism, stated in a release that its product now supports “privacy-enhancing” technology capable of enabling private transfers and confidential interactions with decentralized finance applications—while meeting regulatory requirements.
OP Labs stated that Privacy Boost is a software development kit and interface that enables communication and data sharing between software programs, commonly known as an API. The company added that it hopes businesses will leverage this technology to build practical applications. OP Labs also noted that Privacy Boost will expand to additional networks in the coming weeks.
Interest in digital assets such as Zcash has reignited, perhaps highlighting a renewed emphasis on privacy in the cryptocurrency space. However, Karl Floersch, co-founder and chief technology officer of OP Labs, said that for many traditional companies eager to conduct on-chain experiments, the concept of fully public transaction amounts, counterparties, and balances has always been untenable.

He said, "We explored a public blockchain vision with a payment service provider, but compliance issues ultimately killed their architecture. We couldn't get so many institutions on-chain until we found a very clear privacy solution."
OP Labs stated in its announcement that its goal is to create a privacy layer accessible to any protocol, indicating its ambitions extend beyond its associated network, which already supports leading DeFi applications such as the lending protocol Aave.
As OP Labs launches its latest product, network platforms like Canton, which limit transaction visibility to involved parties, are actively seeking the favor of existing financial institutions. For example, last month, Visa partnered with Canton, stating it had become the first major payment company to join the protocol supported by DTCC.
Privacy Boost supports self-custody through zero-knowledge proofs, according to OP Labs, which is a cryptographic method for proving something is true without directly revealing known information. This technology also relies on a Trusted Execution Environment (TEE) to enable fast and private transactions.
The company stated that the product's Trusted Execution Environment (TEE) can be customized according to "Know Your Customer" (KYC) regulations—which businesses typically must comply with—and audit requirements. Starknet, a competitor of OP Labs, has a team that promotes similar functionality to enable "private Bitcoin transactions."
Florish stated that a study by OP Labs found that privacy ranks higher than other priorities, such as fees or throughput, even within the cryptocurrency space. Bridging this gap has historically been difficult, given that Ethereum was built on the principle of transparency.
OP Labs stated that Privacy Boost is the culmination of years of engineering work. Last month, the company indicated... laying off 20 people to narrow its focus. Meanwhile, reports indicate that the price of the OP token on the OP mainnet has plummeted approximately 83% over the past year to just above $0.12. CoinGecko.
OP Labs notes that for institutions, the lack of privacy exposes their portfolio positions and trading strategies. For consumer-facing applications, spending habits and transaction records become publicly visible to anyone with internet access.
OP Labs added: "Full transparency introduces legal, competitive, and operational risks. Privacy is no longer an option—it's a prerequisite for mainstream adoption."
This perspective is not new. Last year, Danny Ryan, President of Etherealize, the institutional marketing and product division of the Ethereum ecosystem, stated: Decryption Wall Street’s demand for on-chain privacy will ultimately yield similar fruits for the average user in the cryptocurrency space.
