The Boltzmann Calculator – RoninDojo.


The Boltzmann calculator is a brilliantly crafted python script built into the CLI toolkit of your RoninDojo bitcoin node.

Boltzmann provides users with an elegant solution for calculating the linkability of a given transaction’s inputs & outputs, as well as the transaction’s entropy. It’s also effortless to use. Let’s take a look.

There are plans to integrate Boltzmann into RoninUI; however, for now, to access it, we will need to login into RoninCLI. Open a terminal, or if using Windows install PuTTY.

Now, login to the CLI menu using your Dojo’s IP address, your username (usually “ronindojo”) & the password you created during your node setup. A typical Linux command will look something like this;

ssh [email protected]

RoninDojo’s CLI menu.

From the CLI menu, select option 5, Samourai Toolkit; then, on the following menu, choose option 2, Boltzmann Calculator. You will once again need to supply your password.

As shown in the examples, Boltzmann allows you to enter either a single TXID or multiple comma-separated TXIDs. Enter a TXID into the terminal & You will see details of the inputs/outputs of the transaction, deterministic links, efficiency, entropy & fees.

The example TX above is a typical, single 5×5 Whirlpool Coinjoin, resulting in 1496 different interpretations, 0 deterministic links, a wallet efficiency of 100%, & a total entropy of 10.546 bits & density of 1.054 bits per UTXO.

Now let us look at a typical transaction using poor wallet management. Boltzmann results show no entropy & only a single interpretation. We can also see an example of address reuse, as this same address appears in both the input & output fields of the TX.

Once finished, you can exit Boltzmann by typing “quit”. You’ll be returned to the command prompt & can get back into RoninCLI by simply typing “ronin”.

Your Dojo handles all queries, so there’s no risk of exposing TXIDs or IP addresses on external servers.
