Tuesday marked the launch of a privacy tool by OP Labs, aimed at enticing enterprises into Ethereum’s ecosystem via the OP Mainnet, its layer-2 scaling network. The network, previously known as Optimism, now features “Privacy Boost,” described by OP Labs as a technology facilitating private transfers and confidential interactions with decentralized finance applications while meeting regulatory demands.
Privacy Boost serves as a software development kit and interface for data sharing among programs (API), according to OP Labs. It aims to enable enterprises to develop practical applications. The firm plans to expand Privacy Boost to additional networks in the near future, it noted.
As interest in privacy-focused digital assets like Zcash resurges, traditional firms are finding Ethereum’s transparency unviable for on-chain experimentation, Karl Floersch, co-founder and CTO of OP Labs, told Decrypt. “We were discussing a payments provider’s public-chain strategy, but compliance issues ultimately hindered their plans,” he remarked. “We can’t onboard institutions to our chain without a clear privacy solution.”
OP Labs aims to develop a plug-and-play privacy layer for any protocol, indicating ambitions beyond its existing network supporting prominent DeFi applications like Aave. Concurrently, networks such as Canton are attracting financial incumbents by limiting transaction visibility to relevant parties. Last month, Visa became the first significant payments company on the DTCC-backed Canton network.
Privacy Boost employs zero-knowledge proofs for self-custody, allowing proof of truth without revealing underlying data, and Trusted Execution Environments (TEEs) for fast, private transactions. It can be customized to meet KYC regulations and audit requirements. Starknet, a competitor, has noted similar capabilities in enabling private Bitcoin transactions.
A study by OP Labs found that within the crypto community, privacy is prioritized over factors like fees or throughput, despite Ethereum’s transparency-focused origins. Privacy Boost represents years of engineering effort from OP Labs. The firm recently reduced its workforce by 20 to focus efforts. Meanwhile, the price of OP Mainnet’s OP token has dropped approximately 83% to just over $0.12 in the past year, CoinGecko reports.
Institutions face exposure of portfolio positions and trading strategies due to lack of privacy, according to OP Labs. In consumer applications, spending habits and transaction histories become public. “Full transparency introduces legal, competitive, and operational risks,” added OP Labs. “Privacy is now essential for widespread adoption.” This perspective aligns with Danny Ryan’s previous comments that Wall Street’s on-chain privacy needs would benefit the broader crypto community.
