Resources on Lightning privacy
- lnproxy takes a bolt 11 invoice and generates a “wrapped” invoice that can be settled if and only if the original invoice is settled. The “wrapped” invoice has the same payment hash, expiry, and description, as the invoice it wraps but adds a small routing fee to the amount. The “wrapped” invoice can be used anywhere the original invoice would be used to trustlessly hide the destination of a payment.
- use the API in your
.bashrc(available in the Raspiblitz v1.9.0 and above with a CLI shortcut as well):function lnproxy() {echoecho "Requesting a wrapped invoice from http://rdq6tvulanl7aqtupmoboyk2z3suzkdwurejwyjyjf4itr3zhxrm2lad.onion ..."echotorify curl http://rdq6tvulanl7aqtupmoboyk2z3suzkdwurejwyjyjf4itr3zhxrm2lad.onion/api/${1}} -
- use paralell private channels to hide capacity and UTXOs
- To hide public channel balances, a node may open unannounced channels in parallel to announced ones. Depending on the relation between the balances of announced and unannounced channels, the attacker may still be able to discover unannounced channel balances (e.g., if the balance of the unannounced channel exceeds the balances of announced channels). Even in that case, the standard probing technique needs to be modified
- create channels from coinjoin outputs
- private channels are not announced, use them especially if there is a public channel to the peer already
- open one channel at a time
- create no change
- avoid round amounts
- close cooperatively to an external address (eg a Joinmarket wallet running as a Maker))
- Creating a Core Lightning channel funded by JoinMarket: https://gist.github.com/BitcoinWukong/0c04d9186251b0a6497fef3737e95ceb
- syntax for LND with Balance of Satoshis:bos open PUBKEY --amount SATS --coop-close-address EXTERNAL_ADDRESS --type private --external-funding
- LDK / Sensei based
- a new node for every channel open
- fund channels with an external wallet and no change
- Payjoin to channels. The receiver of a paymant can open channels in a payjoin.
Tor support and private chain info
- OBW - Tor + Electrum server support
- optional custodial hosted channels support - payments are private from the provider
- Breez - Tor and neutrino backend
- Blixt - Neutrino block source
Traditional custodians provide no privacy from the maintainer.
- Wallet of Satoshi
- Bitcoin Beach Wallet (phone number required)
- CoinOS (Liquid compatible LN <-> Liquid gateway)
- Fedimint with LN gateways - WIP
