Bitgould: Explain wikitable category criteria

[[PayJoin]] is a privacy improvement for bitcoin. Payjoin solves the sole privacy problem left open in the [[Bitcoin whitepaper]], that transactions with multiple inputs "necessarily reveal that their inputs were owned by the same owner," because both the sender and receiver of a transfer contribute inputs to the transaction.

[[Transaction surveillance company|Transaction surveillance companies]] heavily depend on the [[Common-input-ownership heuristic|common input ownership assumption]] which is broken by PayJoin transactions. So if those transactions became even a little bit widespread they could massively decrease the reliability of blockchain surveillance. Those who adopt PayJoin would find their privacy improved from strangers analyzing the blockchain. For example a surveillance company spy would find it much harder to figure out which addresses and transactions belonged to a particular merchant that was using PayJoin, or who else transacted to them.

PayJoin transactions can be made indistinguishable from regular bitcoin transactions by design, so it's very hard to get an accurate number for how common they are.

The most widely adopted PayJoin protocol standard is [[BIP 0078]].

PayJoin adoption

2023-07-17T16:10:32Z

Bitgould: replace Draft PR with Live Draft

[[PayJoin]] is a privacy improvement for bitcoin. Payjoin solves the sole privacy problem left open in the [[Bitcoin whitepaper]], that transactions with multiple inputs "necessarily reveal that their inputs were owned by the same owner," because both the sender and receiver of a transfer contribute inputs to the transaction.

[[Transaction surveillance company|Transaction surveillance companies]] heavily depend on the [[Common-input-ownership heuristic|common input ownership assumption]] which is broken by PayJoin transactions. So if those transactions became even a little bit widespread they could massively decrease the reliability of blockchain surveillance. Those who adopt PayJoin would find their privacy improved from strangers analyzing the blockchain. For example a surveillance company spy would find it much harder to figure out which addresses and transactions belonged to a particular merchant that was using PayJoin, or who else transacted to them.

PayJoin transactions can be made indistinguishable from regular bitcoin transactions by design, so it's very hard to get an accurate number for how common they are.

The most widely adopted PayJoin protocol standard is [[BIP 0078]].

PayJoin adoption

2023-07-17T02:01:44Z

Bitgould: Update BDK-CLI Draft PR

[[PayJoin]] is a privacy improvement for bitcoin. Payjoin solves the sole privacy problem left open in the [[Bitcoin whitepaper]], that transactions with multiple inputs "necessarily reveal that their inputs were owned by the same owner," because both the sender and receiver of a transfer contribute inputs to the transaction.

[[Transaction surveillance company|Transaction surveillance companies]] heavily depend on the [[Common-input-ownership heuristic|common input ownership assumption]] which is broken by PayJoin transactions. So if those transactions became even a little bit widespread they could massively decrease the reliability of blockchain surveillance. Those who adopt PayJoin would find their privacy improved from strangers analyzing the blockchain. For example a surveillance company spy would find it much harder to figure out which addresses and transactions belonged to a particular merchant that was using PayJoin, or who else transacted to them.

PayJoin transactions can be made indistinguishable from regular bitcoin transactions by design, so it's very hard to get an accurate number for how common they are.

The most widely adopted PayJoin protocol standard is [[BIP 0078]].

PayJoin adoption

2023-07-17T01:25:15Z

Bitgould: Add Blink

[[PayJoin]] is a privacy improvement for bitcoin. Payjoin solves the sole privacy problem left open in the [[Bitcoin whitepaper]], that transactions with multiple inputs "necessarily reveal that their inputs were owned by the same owner," because both the sender and receiver of a transfer contribute inputs to the transaction.

[[Transaction surveillance company|Transaction surveillance companies]] heavily depend on the [[Common-input-ownership heuristic|common input ownership assumption]] which is broken by PayJoin transactions. So if those transactions became even a little bit widespread they could massively decrease the reliability of blockchain surveillance. Those who adopt PayJoin would find their privacy improved from strangers analyzing the blockchain. For example a surveillance company spy would find it much harder to figure out which addresses and transactions belonged to a particular merchant that was using PayJoin, or who else transacted to them.

PayJoin transactions can be made indistinguishable from regular bitcoin transactions by design, so it's very hard to get an accurate number for how common they are.

The most widely adopted PayJoin protocol standard is [[BIP 0078]].

PayJoin adoption

2023-06-28T12:56:00Z

Bitgould: Update Mutiny Send Planned

[[PayJoin]] is a privacy improvement for bitcoin. Payjoin solves the sole privacy problem left open in the [[Bitcoin whitepaper]], that transactions with multiple inputs "necessarily reveal that their inputs were owned by the same owner," because both the sender and receiver of a transfer contribute inputs to the transaction.

[[Transaction surveillance company|Transaction surveillance companies]] heavily depend on the [[Common-input-ownership heuristic|common input ownership assumption]] which is broken by PayJoin transactions. So if those transactions became even a little bit widespread they could massively decrease the reliability of blockchain surveillance. Those who adopt PayJoin would find their privacy improved from strangers analyzing the blockchain. For example a surveillance company spy would find it much harder to figure out which addresses and transactions belonged to a particular merchant that was using PayJoin, or who else transacted to them.

PayJoin transactions can be made indistinguishable from regular bitcoin transactions by design, so it's very hard to get an accurate number for how common they are.

The most widely adopted PayJoin protocol standard is [[BIP 0078]].

PayJoin adoption

2023-06-05T13:26:50Z

Bitgould: Add CLN Evaluating

[[PayJoin]] is a privacy improvement for bitcoin. Payjoin solves the sole privacy problem left open in the [[Bitcoin whitepaper]], that transactions with multiple inputs "necessarily reveal that their inputs were owned by the same owner," because both the sender and receiver of a transfer contribute inputs to the transaction.

[[Transaction surveillance company|Transaction surveillance companies]] heavily depend on the [[Common-input-ownership heuristic|common input ownership assumption]] which is broken by PayJoin transactions. So if those transactions became even a little bit widespread they could massively decrease the reliability of blockchain surveillance. Those who adopt PayJoin would find their privacy improved from strangers analyzing the blockchain. For example a surveillance company spy would find it much harder to figure out which addresses and transactions belonged to a particular merchant that was using PayJoin, or who else transacted to them.

PayJoin transactions can be made indistinguishable from regular bitcoin transactions by design, so it's very hard to get an accurate number for how common they are.

The most widely adopted PayJoin protocol standard is [[BIP 0078]].

PayJoin adoption

2023-05-20T20:41:01Z

Bitgould: Show SatSale Planned

[[PayJoin]] is a privacy improvement for bitcoin. Payjoin solves the sole privacy problem left open in the [[Bitcoin whitepaper]], that transactions with multiple inputs "necessarily reveal that their inputs were owned by the same owner," because both the sender and receiver of a transfer contribute inputs to the transaction.

[[Transaction surveillance company|Transaction surveillance companies]] heavily depend on the [[Common-input-ownership heuristic|common input ownership assumption]] which is broken by PayJoin transactions. So if those transactions became even a little bit widespread they could massively decrease the reliability of blockchain surveillance. Those who adopt PayJoin would find their privacy improved from strangers analyzing the blockchain. For example a surveillance company spy would find it much harder to figure out which addresses and transactions belonged to a particular merchant that was using PayJoin, or who else transacted to them.

PayJoin transactions can be made indistinguishable from regular bitcoin transactions by design, so it's very hard to get an accurate number for how common they are.

The most widely adopted PayJoin protocol standard is [[BIP 0078]].

[[PayJoin]] is a privacy improvement for bitcoin.

PayJoin adoption

2023-05-04T02:55:11Z

Bitgould: Specify Non-BIP78 tech being used

[[PayJoin]] is a privacy improvement for bitcoin. Payjoin solves the sole privacy problem left open in the [[Bitcoin whitepaper]], that transactions with multiple inputs "necessarily reveal that their inputs were owned by the same owner," because both the sender and receiver of a transfer contribute inputs to the transaction.

[[Transaction surveillance company|Transaction surveillance companies]] heavily depend on the [[Common-input-ownership heuristic|common input ownership assumption]] which is broken by PayJoin transactions. So if those transactions became even a little bit widespread they could massively decrease the reliability of blockchain surveillance. Those who adopt PayJoin would find their privacy improved from strangers analyzing the blockchain. For example a surveillance company spy would find it much harder to figure out which addresses and transactions belonged to a particular merchant that was using PayJoin, or who else transacted to them.

PayJoin transactions can be made indistinguishable from regular bitcoin transactions by design, so it's very hard to get an accurate number for how common they are.

The most widely adopted PayJoin protocol standard is [[BIP 0078]].

Bitgould: Track dual-funded channels (DFC) as Non-BIP78 payjoin

[[PayJoin]] is a privacy improvement for bitcoin. Payjoin solves the sole privacy problem left open in the [[Bitcoin whitepaper]], that transactions with multiple inputs "necessarily reveal that their inputs were owned by the same owner," because both the sender and receiver of a transfer contribute inputs to the transaction.

[[Transaction surveillance company|Transaction surveillance companies]] heavily depend on the [[Common-input-ownership heuristic|common input ownership assumption]] which is broken by PayJoin transactions. So if those transactions became even a little bit widespread they could massively decrease the reliability of blockchain surveillance. Those who adopt PayJoin would find their privacy improved from strangers analyzing the blockchain. For example a surveillance company spy would find it much harder to figure out which addresses and transactions belonged to a particular merchant that was using PayJoin, or who else transacted to them.

PayJoin transactions can be made indistinguishable from regular bitcoin transactions by design, so it's very hard to get an accurate number for how common they are.

The most widely adopted PayJoin protocol standard is [[BIP 0078]].

Bitgould: Show wallets evaluating payjoin integration

[[PayJoin]] is a privacy improvement for bitcoin. In the case where a customer pays a merchant, they both together co-operate to create a single bitcoin transaction which mixes both their coins and masks the payment amount.

[[Transaction surveillance company|Transaction surveillance companies]] heavily depend on the [[Common-input-ownership heuristic|common input ownership assumption]] which is broken by PayJoin transactions. So if those transactions became even a little bit widespread they could massively decrease the reliability of blockchain surveillance. Merchants and customers who adopt PayJoin would find their privacy improved from anyone analyzing the blockchain, for example a surveillance company spy would find it much harder to figure out which addresses and transactions belonged to a particular merchant that was using PayJoin, or who else transacted to them.

PayJoin transactions are indistinguishable from regular bitcoin transactions by design, so it's very hard to get an accurate number for how common they are.

The PayJoin protocol standard most likely to get adoption is [[BIP 0078]].

Like any new feature, PayJoin requires a little bit of time to first set up. But if your business suffers from being spied on (for example you're a p2p exchange or bitcoin casino, and regulated exchanges keep banning your customers) then that cost is well worth it.

PayJoin adoption

2023-04-24T13:54:24Z

Bitgould: Add bluewallet support fix

[[PayJoin]] is a privacy improvement for bitcoin. In the case where a customer pays a merchant, they both together co-operate to create a single bitcoin transaction which mixes both their coins and masks the payment amount.

[[Transaction surveillance company|Transaction surveillance companies]] heavily depend on the [[Common-input-ownership heuristic|common input ownership assumption]] which is broken by PayJoin transactions. So if those transactions became even a little bit widespread they could massively decrease the reliability of blockchain surveillance. Merchants and customers who adopt PayJoin would find their privacy improved from anyone analyzing the blockchain, for example a surveillance company spy would find it much harder to figure out which addresses and transactions belonged to a particular merchant that was using PayJoin, or who else transacted to them.

PayJoin transactions are indistinguishable from regular bitcoin transactions by design, so it's very hard to get an accurate number for how common they are.

The PayJoin protocol standard most likely to get adoption is [[BIP 0078]].

Like any new feature, PayJoin requires a little bit of time to first set up. But if your business suffers from being spied on (for example you're a p2p exchange or bitcoin casino, and regulated exchanges keep banning your customers) then that cost is well worth it.

PayJoin adoption

2023-04-05T16:09:05Z

Bitgould:

[[PayJoin]] is a privacy improvement for bitcoin. In the case where a customer pays a merchant, they both together co-operate to create a single bitcoin transaction which mixes both their coins and masks the payment amount.

[[Transaction surveillance company|Transaction surveillance companies]] heavily depend on the [[Common-input-ownership heuristic|common input ownership assumption]] which is broken by PayJoin transactions. So if those transactions became even a little bit widespread they could massively decrease the reliability of blockchain surveillance. Merchants and customers who adopt PayJoin would find their privacy improved from anyone analyzing the blockchain, for example a surveillance company spy would find it much harder to figure out which addresses and transactions belonged to a particular merchant that was using PayJoin, or who else transacted to them.

PayJoin transactions are indistinguishable from regular bitcoin transactions by design, so it's very hard to get an accurate number for how common they are.

The PayJoin protocol standard most likely to get adoption is [[BIP 0078]].

Like any new feature, PayJoin requires a little bit of time to first set up. But if your business suffers from being spied on (for example you're a p2p exchange or bitcoin casino, and regulated exchanges keep banning your customers) then that cost is well worth it.
