OP Labs launches the Privacy Boost privacy product, offering enterprise on-chain privacy solutions

According to Decrypt’s report on April 22, OP Labs rolled out its privacy product Privacy Boost on Tuesday, with the first deployment on the OP mainnet, aiming to draw enterprises into the Ethereum ecosystem. OP Labs said in an announcement that Privacy Boost is an SDK and API interface that supports businesses in making private transfers and carefully interacting with DeFi applications while meeting regulatory requirements.

Privacy Boost Product Specs and Technical Architecture

According to OP Labs’ announcement, the main technical features of Privacy Boost are as follows:

Technical foundation: Supports data self-custody through zero-knowledge proofs (ZKP) and enables fast private transactions using a trusted execution environment (TEE)

Enterprise customization: Can be configured according to a company’s KYC (know your customer) rules and auditing requirements

Product form: SDK and API interface, supporting integration with various protocols

Deployment plan: First goes live on the OP mainnet, with plans to expand to more blockchain networks in the coming weeks

OP Labs said Privacy Boost is the result of “years of engineering research and development,” aiming to build a privacy layer that any protocol can integrate with.

OP Labs CTO Karl Floersch: Compliance issues block institutions from going on-chain

In comments to Decrypt during an interview, Karl Floersch, co-founder and chief technology officer of OP Labs, said, “We once discussed their public-chain vision with a payment service provider, but ultimately, compliance issues killed their architecture. Until we find a very clear privacy solution, we can’t onboard so many institutions.”

OP Labs noted in its announcement: “Full transparency brings legal, competitive, and operational risks. Privacy is no longer optional—it’s a prerequisite for mainstream applications.” The OP mainnet currently supports leading DeFi lending protocols such as Aave.

Market backdrop: Competition from Canton Network and the company’s latest situation

According to Decrypt’s report, as OP Labs launched Privacy Boost, Canton Network (an institutional blockchain supported by DTCC) was actively seeking to attract traditional financial institutions; its competitor Starknet’s team had also previously promoted similar private-transaction functionality.

OP Labs announced last month that it would lay off 20 people to reduce its business scale. Based on CoinGecko data, the price of the OP token has fallen by about 83% over the past year and is currently slightly above $0.12.
