Sometimes even tools for privacy (like blockchains) need a blockchain for secure transparent transmission of sensitive information. Yes, even blockchains need blockchains to share secrets over public blockchains.That is why NuCypher works like a password manager for blockchain users to establish trust and consensus. As an Ethereum L2, NuCypher helps send private messages on public networks. Similar to sharing private documents over the internet, NuCypher controls who has access to what data and for how long. Sending private information over public networks is an important feature for secure business communications but blockchains are often designed for transparency. NuCypher balances that transparency by enabling precision control over personal privacy.
