Whats unique about brainbow?
Great marketing 😅
Brainbow is a secure, stateless Bitcoin brainwallet app that offers a secure and private way to manage your bitcoin.
It uses a variant of the WarpWallet technique for key derivation, which is both memory and time-intensive, improving security compared to typical brainwallets.
Brainbow operates through Electrum servers (either yours or community-trusted) and exclusively communicates over Tor (with optional clearnet communication possibly added later).
It aims to provide an easy-to-use, secure solution for storing bitcoin without physical wallets, particularly useful in scenarios like border crossings where physical possessions might be searched.
Secure your credential-based keys using a standard BIP-39 12-word recovery seed phrase.
You can use the credential-based keys in a multi-sig quorum or as a fallback key for Liana.
