Coinbase CEO Brian Armstrong Announces Private Transactions on Base
Coinbase is integrating privacy-preserving transactions into its Base layer-2 network, supported by the Iron Fish team acquisition, amid growing interest and regulatory scrutiny of privacy coins.
Coinbase CEO Brian Armstrong stated the company is developing privacy-focused transaction capabilities for its Base layer-2 network, with more details to follow. The initiative follows Coinbase’s March 2025 acquisition of the team behind Iron Fish, known for privacy-preserving blockchain technologies, now integrated into Base’s new “privacy pod.” While Iron Fish remains an independent blockchain, its engineers are working on privacy primitives for Base. The announcement comes amid a surge in privacy coin prices, such as ZEC, XMR, and DASH, despite global regulatory crackdowns over illicit use concerns. Research shows only around 7% of privacy coin transactions link to suspected illicit activity, with just 0.14% of all crypto transactions deemed illicit.
- Base: A layer-2 blockchain network developed by Coinbase, designed to offer faster and cheaper transactions compared to Ethereum mainnet.
- Private Transactions: Blockchain transactions designed to conceal sensitive details such as sender, receiver, and amounts while maintaining network validity.
- Privacy Coins: Cryptocurrencies that use advanced cryptographic techniques to enhance transaction privacy, making it difficult to trace transaction details.
