Extracting Monero Wallet Seeds From Addresses with a Quantum Computer

Wallet Derivation Assumputions

1. Not multisig
2. The private spend key is the seed src
3. The private view key is a hash of solely the private spend key src
4. Subaddresses are generated by adding the public spend key to a base point multiplied by a scalar hash of the private view key and a small "index" space src

This is not the exact math, but here is a simplified deriviation scheme which preserves all the relationships that we care about:

Short On-chain Memos Encrypted in Carrot Anchors in Two-out Selfsends

What

SOME CATS is a scheme to send 16-byte transaction memos in 2-out transactions using Carrot. SOME CATS memos are:

• Encrypted - Memos are encrypted to the receiver, optionally visible to the sender as well
• Indistinguishable - Transactions containing a SOME CATS memo are indistinguishable from normal Carrot transactions
• Available on-chain - The memo will always be available on-chain as long as its associated transaction is
• Receiver agnostic - The receiver doesn't need to support SOME CATS to spend funds sent in a SOME CATS transaction, so long as they support the Carrot addressing protocol

Carrot Recoverable Indistinguishable Blinded Proof Of Existence before Timestamp

What

CRIBPOET lets you prove you knew about information before some point in time by posting a Carrot transaction from your wallet to the Monero blockchain.

• Carrot - Uses the Carrot addressing protocol, so any wallet with the new Carrot key hierarchy will have the ability to support this scheme by default
• Indistinguishable - Uses steganography to look like a regular old 2-out transaction
• Blinded - The commitment to the information contains a blinding factor that makes it impossible to guess the message from the commitment
• Recoverable - The blinding factor is recoverable through normal Carrot balance recovery, which means you don't have to keep track of any ephemeral information.
