Greta’s Fury

A crowdfunded campaign to signal the end of life for common input ownership heuristics. Organized by BitcoinEnemies.

Objective

Distribute heuristic breaking txs

Work together to contaminate common input ownership heuristics used by chain analysis. Help improve Bitcoin privacy by paying mining fees to pollute the transaction graph with a 1 satoshi Stowaway payment.

Instructions

1) Find Partner

Locate a partner and follow each others PayNyms. A commit tx is not required.

2) Pollute graph

Send 1 sat using Soroban Stowaway to the Paynym of your choosing.

3) Submit signature

Sign a defaults message using the change output from your 1 sat send and submit.

4) Repeat

Get multiple entries and compete for prizes by completing the most Stowaways.

FAQ

Why send 1 satoshi?
This allows us to pollute the transaction graph with on-chain payments below the dust limit, while also reducing the incentive to steal.

What is a PayNym?
A PayNym helps generate unique unused bitcoin addreses using BIP47 payment codes. It does this without revealing prior transaction or balance history. Claim yours here.

What is Soroban?
Soroban allows you to easily collaborate online with a Cahoots peer. This eliminates the need for exchanging QR codes to construct and broadcast peer collaborated transactions.

What is Stowaway?
A Stowaway looks like an ordinary transaction. The actual amount sent is concealed. To send a Stowaway, the receiver must collaborate in the transaction.

How to sign?
Long tap wallet balance to load UTXO management screen. Select change output received from 1 sat send. Tap ‘Sign Message’ and select yes. Copy and upload to submit.bitcoinenemies.com.
