# Bitcoin Multi-Sig Transaction
Quick PoC to transact Bitcoins in a single transaction with multiple participants. Helps obscure coin flow and might even reduce transaction size _(and thus transaction costs)_.
Part of this blog post: [Bringing Obfuscation to the Bitcoin Blockchain](https://ferib.dev/blog.php?l=post/Bringing_Obfuscation_to_the_Bitcoin_Blockchain)
## Example
Alice and Bob both agreed to send exactly `0.00000600` BTC to their target of choice. The below transaction obfuscated the coin flow as you can no longer differentiate who owns which output of `0.00000600` BTC.
