The following firmware launch for the Founder’s Version will likely be similar to the Batch 2 firmware.
This completes the comparisons part. Within the subsequent part, you will note methods to use choose options of the Passport.
Passport And Whirlpool
Whirlpool is a zero-link CoinJoin implementation supported by Samourai Pockets on Android cellular gadgets and by Sparrow Pockets on Linux, Mac and Home windows desktops. Zero-link CoinJoin signifies that there are not any deterministic hyperlinks between the inputs and outputs of the CoinJoin transaction. As a result of a number of entities are concerned with every CoinJoin, there can’t be any certainty as to which entity owns which transaction output. CoinJoins can be utilized as a way to achieve anonymity on a public blockchain, placing the choice to selectively reveal particulars about your self again in your arms, thus providing you with a layer of privateness separating your real-world identification from the transactions on a public ledger.
Passport helps Whirlpool accounts and this part will display methods to setu p and use this function on Bitcoin’s testnet. All of the steps are the identical for Bitcoin’s mainnet. There will likely be two wallets used on this demonstration; the primary is Sparrow Pockets, performing as the new pockets which is the pockets the place the CoinJoin transactions will originate from, and the second is Passport, performing because the chilly pockets the place the outputs from the new pockets CoinJoins will likely be deposited.
Utilizing this method presents a pair advantages. First, every deposit to the Passport will seem like each different CoinJoin output to exterior observers on chain and, subsequently, nobody aside from you’ll know that these unspent transaction outputs (UTXOs) are actually in chilly storage. So, as different CoinJoin members proceed mixing the opposite UTXOs out of your CoinJoin transactions, the forward-looking anonymity set of your UTXOs in chilly storage continues to develop.
One other profit is that the Whirlpool account on Passport was designed in such a method which you could import it to a scorching pockets at any time sooner or later and proceed mixing these UTXOs as free-riders in Whirlpool, thus saving your self from paying the coordinator charges a second time. Moreover, you will not pay any extra miners charges when importing this account to a scorching pockets sooner or later versus sweeping UTXOs. Perceive, although, that importing the Whirlpool account to a scorching pockets exposes the seed to an internet-connected machine and subsequently it’s endorsed to make use of a separate seed in your Passport for any accounts you intend on doing this with.
Scorching Pockets
This information assumes you have got already put in Sparrow Pockets in your most well-liked desktop.

Then, click on on “New or Imported Software program Pockets”:
A window will pop up, — click on on the drop-down menu within the higher right-hand nook to pick the variety of phrases you need to use in your scorching pockets’s seed phrase (also referred to as the “mnemonic phrase”):
A 12-word seed phrase was chosen for this demonstration. After you have made your choice, the corresponding variety of clean bins will seem within the pop-up window. Click on on “Generate New” and Sparrow Pockets will generate a random seed phrase:
You possibly can add a passphrase or go away that subject clean. That is type of like having a thirteenth or twenty fifth phrase added to your seed phrase that solely you understand. There isn’t a solution to get better a misplaced or forgotten passphrase and this will likely be essential to entry your bitcoin going ahead if you happen to determine to make use of it.
Ensure to write down down your seed phrase phrases so as and hold them protected. Additionally write down your passphrase if you happen to determined to make use of one. Contemplate protecting your seed phrase and passphrase separate from one another to assist stop lack of funds within the occasion that your secrets and techniques are found. Scripting this info down in a pocket book or stamping it into steel to guard it towards environmental hazards are widespread ways in which Bitcoiners hold their backups protected and safe. Anybody who positive factors entry to this info will be capable to steal your bitcoin, so be sure you hold it protected.

You’ll be offered with an inventory of accounts you may add; on the backside of that record choose “Whirlpool Accounts”:
Then choose “OK”:
You’ll discover now that a number of tabs have appeared alongside the left-hand aspect of the person interface. These are the 4 accounts used to make Whirlpool work. The primary one is the deposit account the place you’ll want to ship bitcoin that you just need to CoinJoin. From the deposit tab, you may click on on the obtain sub-tab to show a QR code for one in all your receiving addresses and you may ship bitcoin to it.
After you have made a number of deposits to your scorching pockets, you may click on on the UTXOs sub-tab to see your obtainable outputs. Choose those you need to CoinJoin or use the “Choose All” choice to make use of all of them. Simply remember the fact that deciding on all will hyperlink all of those UTXOs collectively on chain within the subsequent step, previous to them being CoinJoined. If you do not need them linked on chain, then simply combine one after the other.
After you have your choice made, click on on “Combine Chosen”:
A window will pop up and, when you have an SCODE for decreased coordinator charges, then you may enter it right here.

Then you may select the pool dimension you need to be part of. There are 4 sizes to select from, the 100,000 sat pool dimension was used on this demonstration which is able to create 20 UTXOs which might be all 100,000 sats every. The coordinator charge for that is 5,000 sats. Click on on “Preview Premix” as soon as prepared:
Then you will note a abstract of the transaction you simply constructed. This transaction is known as “tx0” and you’ll discover that the entire chosen inputs of assorted sizes and from varied addresses are consumed on this transaction and 20 like-sized outputs are created. These like-sized outputs from tx0 will likely be used as eligible inputs to Whirlpool CoinJoin transactions. There are three different outputs in a tx0 as nicely; the coordinator charge, the poisonous change and the miners’ charge. If the whole lot appears good, then click on on “Broadcast Premix Transaction”:
Then your pockets will ship your transaction to the Bitcoin community:
From the deposit tab and the transactions sub-tab, it is possible for you to to see that the bitcoin you deposited to this account has been despatched out:
Then, if you happen to click on on the premix tab and the transactions sub-tab, you will note the bitcoin out of your deposit account is now in your premix account:
As long as your pockets is linked to the web, then your obtainable like-sized outputs in your premix account will likely be registered as eligible inputs for the coordinator to make use of in CoinJoin rounds. As extra members add liquidity, extra of your premix outputs will likely be CoinJoined. After going via a CoinJoin spherical, every UTXO will seem in your post-mix account, which you’ll view from the post-mix tab and the transactions sub-tab. As long as you permit your pockets open and linked, the UTXOs in your post-mix account will stay obtainable as eligible inputs to CoinJoin rounds as free-riders, the place they get combined time and again with no added charges to you:

Chilly Pockets
Now that you’ve your scorching pockets established and a few bitcoin being CoinJoined in Whirlpool, you may arrange the chilly pockets extension in your Passport. This would be the account you might be sending your CoinJoined outputs to for long-term chilly storage. Utilizing a separate seed out of your major chilly storage seed for this course of is really useful. If you wish to import it to a scorching pockets at any time sooner or later and proceed mixing these UTXOs as free-riders, it’ll expose the seed to an web linked machine.
