[bug] deadlock on add_validation_token

* Device is an unlogged user that is just able to scan incoming
  transactions
* There's always a Device defined either we load one from indexedDB or
  create one
* Logged users have a defined SPENDING_CLIENT that can sign transactions
* The pairing phase is when a new Device is created, we need another
  Device to send it it's own spending key via normal 4nk messaging
* The new Device then encrypt it and send it back
* In another transaction, the first Device does the exact same thing
  (probably possible to optimize)
* The logging phase is sending a 4nk message with the encrypted spending
  key and getting the clear key back, basically logging with one device
of a pair is the same operation than pairing but in reverse
* Revokation output is an unique output for both devices, the validity
  of the pair depends of it being unspent
* Revokation output is locked with some random key that both devices
  will need to keep
* Todo: 1. implement the revokation scheme
2. optimize the pairing/logging flow

-# Editing this README
-
-When you're ready to make this README your own, just edit this file and use the handy template below (or feel free to structure it however you want - this is just a starting point!). Thanks to [makeareadme.com](https://www.makeareadme.com/) for this template.
-
-## Suggestions for a good README
-
-Every project is different, so consider which of these sections apply to yours. The sections used in the template are suggestions for most open source projects. Also keep in mind that while a README can be too long and detailed, too long is better than too short. If you think your README is too long, consider utilizing another form of documentation rather than cutting out information.
-
-## Name
-Choose a self-explaining name for your project.
-
-## Description
-Let people know what your project can do specifically. Provide context and add a link to any reference visitors might be unfamiliar with. A list of Features or a Background subsection can also be added here. If there are alternatives to your project, this is a good place to list differentiating factors.
-
-## Badges
-On some READMEs, you may see small images that convey metadata, such as whether or not all the tests are passing for the project. You can use Shields to add some to your README. Many services also have instructions for adding a badge.
-
-## Visuals
-Depending on what you are making, it can be a good idea to include screenshots or even a video (you'll frequently see GIFs rather than actual videos). Tools like ttygif can help, but check out Asciinema for a more sophisticated method.
-
-## Installation
-Within a particular ecosystem, there may be a common way of installing things, such as using Yarn, NuGet, or Homebrew. However, consider the possibility that whoever is reading your README is a novice and would like more guidance. Listing specific steps helps remove ambiguity and gets people to using your project as quickly as possible. If it only runs in a specific context like a particular programming language version or operating system or has dependencies that have to be installed manually, also add a Requirements subsection.
-
-## Usage
-Use examples liberally, and show the expected output if you can. It's helpful to have inline the smallest example of usage that you can demonstrate, while providing links to more sophisticated examples if they are too long to reasonably include in the README.
-
-## Support
-Tell people where they can go to for help. It can be any combination of an issue tracker, a chat room, an email address, etc.
-
-## Roadmap
-If you have ideas for releases in the future, it is a good idea to list them in the README.
-
-## Contributing
-State if you are open to contributions and what your requirements are for accepting them.
-
-For people who want to make changes to your project, it's helpful to have some documentation on how to get started. Perhaps there is a script that they should run or some environment variables that they need to set. Make these steps explicit. These instructions could also be useful to your future self.
-
-You can also document commands to lint the code or run tests. These steps help to ensure high code quality and reduce the likelihood that the changes inadvertently break something. Having instructions for running tests is especially helpful if it requires external setup, such as starting a Selenium server for testing in a browser.
-
-## Authors and acknowledgment
-Show your appreciation to those who have contributed to the project.
-
-## License
-For open source projects, say how it is licensed.
-
-## Project status
-If you have run out of energy or time for your project, put a note at the top of the README saying that development has slowed down or stopped completely. Someone may choose to fork your project or volunteer to step in as a maintainer or owner, allowing your project to keep going. You can also make an explicit request for maintainers.

+#[wasm_bindgen_test]
+/// Tests the connection process between two devices, Alice and Bob, by executing a secure
+/// transaction to establish a shared secret for encrypted communication.
+/// 
+/// The basics are that one device will initiate the process by sending a transaction that pays another device.
+/// The recipient of the transaction as soon as it finds it, can extract a shared secret and send an encrypted 
+/// message back. Upon receiving this message, the initiator answers with a similar message similarly encrypted.
+/// Upon receiving this message, the recipient can be assured that the communication is safe, and start using
+/// the secret to communicate.
+/// 
+/// The security of the shared secret rest on the soundness of the silent payment protocol for Bitcoin.
+/// In its encrypted response, the initiator adds a signature that is proof that it indeed controls the 
+/// private key for the silent payment address it announced, so recipient knows there's no mitm or impostor.
+///
+/// # Detailed Process
+///
+/// ## Alice sends a transaction that pays Bob:
+/// - Alice initializes her device from an `sp_wallet` object and sets it as the local device.
+/// - She retrieves her own address and obtains Bob’s address.
+/// - Alice creates a new member using Bob’s device address (this is mainly for testing purpose, 
+///   because `create_connection_transaction` would take members as argument).
+/// - She generates a connection transaction (`connect_tx`) targeting Bob's device.
+/// - Alice processes her own transaction and stores the derived shared secrets in `alice_secrets_store`,
+///   associating the shared secret with Bob's addresses.
+///
+/// ## Bob parses the transaction:
+/// - Bob initializes his device from his own `sp_wallet`.
+/// - He parses Alice’s connection transaction to retrieve the shared secret Alice created for him.
+/// - Bob saves these derived shared secrets in `bob_secrets_store` but can't index it with Alice's address yet.
+///
+/// ## Prd Connect exchange
+/// - Bob then responds by sending a prd connect back to Alice encrypted with the shared secret.
+///   This prd is very simple and basically contains the following:
+///     * All Bob's devices addresses
+///     * a commitment to the shared secret
+///     * a proof signed with Bob's device spend key
+/// - Alice receives and decrypts the message from Bob.
+/// - She replies to Bob by encrypting another prd connect which is basically the same, but keeping Bob's proof and adding her own.
+/// - **Bob’s Confirmation**: Bob receives Alice’s confirmation message, decrypts it, and updates his secret in `bob_secrets_store`.
+///
+/// ## Verification:
+/// - Finally, the function asserts that Alice and Bob now share the same secrets, confirming successful
+///   connection and mutual authentication between the devices.

+/// # Pairing Process Documentation between Alice and Bob
+///
+/// This test describes the secure pairing process between two devices, Alice and Bob. 
+/// 
+/// ## What's pairing?
+/// Pairing is a process, and abide by the same rules than any other process. The goal of pairing 
+/// is to define an identity on the network as a set of devices (defined by their sp_address).
+/// Being a process it is public and can be audited by anyone, and be used as one's proof of identity.
+/// It also contains a session keypair that is updated as necessary. Since all devices are needed to
+/// update the key in the process it can then be used to sign a proof that someone was indeed in control
+/// of all the devices for some amount of time in a MFA setup. 
+/// It contains the following mandatory fields:
+/// * `roles`: multiple devices represented as sp adresses linked together in the same member. It is recommended 
+///   to have one `owner` role with one member which is the actual identity and whose signatures are all 
+///   needed to modify anything in the process.
+/// * `session_privkey`: a private key visible by all devices of the member defined in the process, but 
+///   not by other members. It *must* be changed at every update of the process. This key will be used
+///   to sign documents and validate actions for other processes. It's valid as soon as the commitment
+///   transaction for the process udpate is seen and it stays valid for _n_ blocks after the update being mined.
+/// * `session_pubkey`: the x-only public key derived from the session private key. It's visible by everyone and 
+///   used for validation by any third party. Obviously it changes with the private key at any update.
+/// * `parity`: the parity of the session_pubkey. We could use 33 bytes compressed public key format 
+///   but using 32 bytes publick key + parity allows for more standard serialization.
+/// 
+/// ## Detailed protocol
+///    (Here Alice and Bob are used as a convention, but keep in mind they're not 2 different users, but 
+///    2 devices belonging to the same user)
+/// ## Step 0 - Preliminary step
+/// 1. **Establishing a Shared Secret**: A shared secret is established to secure
+///    communication between Alice and Bob (see `connect.rs`).
+/// ## Step 1 - Pairing Preparation by Alice
+/// 1. **Pairing Status Check**: Alice verifies that it's not already paired.
+/// 2. **Adding Bob's Address**: Alice adds Bob’s address to her own, setting the base for creating
+///    a new `Member` object.
+/// 3. **Creation of the pairing process**: Alice initializes pairing by creating a prd update that contains 
+///    both its address and Bob's, and send it to Bob.
+///
+/// ## Step 2 - Receiving and Confirming the `prd` by Bob
+/// 1. **Receiving and Verifying**: Bob receives and decrypts the update `prd` message sent by Alice.
+/// 2. **Updating Process State**: Bob identifies the new process and store it, but it doesn't have access 
+///    to the actual data for now.
+/// 3. **Creating and Sending `Prd Confirm`**: Bob creates a confirmation `prd`, which he then
+///    sends to Alice to get the pcd containing the state for this new process.
+///
+/// ## Step 3 - Alice gets confirmation and answers with a pcd
+/// 1. **Receiving and Verifying**: Alice receives the `Prd Confirm` sent by Bob.
+/// 2. **Sending PCD**: Alice having confirmation that Bob got the update proposal,
+///    it now sends the actual data in a pcd.
+/// 3. **User confirmation**: At this step we must get the approval of the user. If user confirms 
+///    the pairing we create a prd response with a valid signature from Alice spend key and send 
+///    it to Bob.
+/// 
+/// ## Step 4 - Finalizing Pairing by Bob
+/// 1. **Receiving and Verifying `pcd`**: Bob received the `pcd` and only now can tell what's the 
+///    process was about. 
+/// 2. **Validating Pairing State**: Bob retrieves the latest process state and the state change
+///    request, in this case, the pairing. User is prompted for validation, and if confirmed a prd response
+///    is created and sent(see the **User confirmation** step for Alice).
+///
+/// ## Commiting the process state
+/// 1. **Creating the `commit_msg`**: The first device that got both validations creates the commit_msg that
+///    contains a transaction paying a relay to generate the first outpoint to commit the state of the process,
+///    the hash of the encrypted state of the process (relay must have access to roles though, either it is clear
+///    all along or it was provided with the encryption keys) and the proofs that all devices validated this state.
+/// 2. **Actual commitment**: As soon as the relay validated the proofs it spends the outpoint and puts the hash of 
+///    the whole prd response (including pcd hash and all the proofs) in an OP_RETURN output. The process is now
+///    public and can be used to prove identity for other processes.
