Silent Payments

Receive private payments from anyone on a single static address without requiring any interaction or extra on-chain overhead.

Update: This now has a BIP and WIP implementation

Overview

The recipient generates a so-called silent payment address and makes it publicly known. The sender then takes a public key from one of their chosen inputs for the payment, and uses it to derive a shared secret that is then used to tweak the silent payment address. The recipient detects the payment by scanning every transaction in the blockchain.

Design for a CoinSwap Implementation for Massively Improving Bitcoin Privacy and Fungibility

25/5/2020

Abstract

Imagine a future where a user Alice has bitcoins and wants to send them with maximal privacy, so she creates a special kind of transaction. For anyone looking at the blockchain her transaction appears completely normal with her coins seemingly going from address A to address B. But in reality her coins end up in address Z which is entirely unconnected to either A or B.

Now imagine another user, Carol, who isn't too bothered by privacy and sends her bitcoin using a regular wallet which exists today. But because Carol's transaction looks exactly the same as Alice's, anybody analyzing the blockchain must now deal with the possibility that Carol's transaction actually sent her coins to a totally unconnected address. So Carol's privacy is improved even though she didn't change her behaviour, and perhaps had never even heard of this software.

Chris Belcher's Work Diary

I keep a diary of all the work I do on bitcoin privacy.

It may also be interesting to my collaborators and donors, and anyone who wants to follow how my projects are going (these days I'm almost exclusively working on developing CoinSwap, see https://gist.github.com/chris-belcher/9144bd57a91c194e332fb5ca371d0964).

The following files show an example of how to create subdomains for onion site hidden services. (This hasn't been tested for hidden services for anything other than HTTP/HTTPS.)

(You might also want to read our blog post about ProPublica’s Tor hidden service, including a tutorial and notes on running a hidden service: https://www.propublica.org/nerds/item/a-more-secure-and-anonymous-propublica-using-tor-hidden-services )

In general, this works (maybe just in recent Tor clients) because Tor will handle the connection to www.xxxxxxxxxxxxxxxx.onion as a connection to xxxxxxxxxxxxxxxx.onion. The encapsulated HTTP/HTTPS connection contains the subdomain in the Host: header (and in the case of HTTPS, the SNI
