-This is a prototype web service that monitors the [P2WDB](https://github.com/Permissionless-Software-Foundation/ipfs-p2wdb-service) for trading signals, to trade BCH and SLP tokens. It's inspired by the [SWaP Prototype](https://github.com/vinarmani/swap-protocol/blob/master/swap-protocol-spec.md).
+`bch-dex` is a decentralized exchange for permissionless trading of [SLP tokens](https://github.com/simpleledger/slp-specifications/blob/master/slp-token-type-1.md) and [NFTs](https://github.com/simpleledger/slp-specifications/blob/master/slp-nft-1.md). Trading fees are incredibly small, compared to other DEX platforms. The software is based entirely on open protocols and open source software. It's not a '.com' website that you visit, but software you run on your own computer, in the confort of your own home. So long as you have an internet connection and the technical knowledge to run this software, no one can stop you from trading tokens. `bch-dex` software is maintained by the [Permissionless Software Foundation](https://psfoundation.cash/).

-## Development Notes
+This is a prototype web service that monitors the [P2WDB](https://github.com/Permissionless-Software-Foundation/ipfs-p2wdb-service) for trading signals, to trade BCH and SLP tokens. It's inspired by the [SWaP Protocol](https://github.com/vinarmani/swap-protocol/blob/master/swap-protocol-spec.md).
+
+This repository contains the back end code. The user interface is contained in the [bch-dex-ui](https://github.com/Permissionless-Software-Foundation/bch-dex-ui) repository.

 **Warning**: This repository is under active development. Things will be constantly changing and breaking.

+- [Developer walk-through for installing and hacking on bch-dex](https://youtu.be/T5XI43-SWJo) (Video)
+  - This video is out of date. Follow the instructions below.

- Phase 1: MVP (single user)
-  - Move tokens or BCH for sale to temporary address.
-  - Accept input from user:
-    - Submit Signal message to P2WDB for new buy/sell order.
-    - Check UTXO status before submitting Payment message.
-  - React to webhook when new Offers come in.
-    - Add and track new Offers in MongoDB.
-    - Process Payment signals:
-      - Checking transaction for compatibility
-      - Broadcast/close trades managed by this app.
- Phase 2: Build single-user web app
-  - _Make_ buy or sell orders.
-  - Browse Offers on the market.
-  - _Take_ buy or sell orders.
- Phase 3: Multi-user
-  - Configure REST API as an IPFS Service that can offer services to multiple users.
-  - Update web app to display and select available SWaP services over IPFS.
+## Participate
+This is an open source project, and we encourage other JavaScript developers to participate in its creation and maintenance. We have two chat rooms for the community:
+- [Telegram Channel](https://t.me/psf_dex_dev)
+- [Gitter Channel](https://gitter.im/Permissionless-Software-Foundation/psf-dex-dev)
+
+## Installation
+Running the DEX requires composition of these different software packages:
+- bch-dex - This repository is the back end software that tracks trade data on the network, generates [Offers and Counter Offers](https://github.com/Permissionless-Software-Foundation/bch-dex/tree/ct-unstable/dev-docs#definitions), and finalizes trades by accepting Counter Offers.
+- [bch-dex-ui](https://github.com/Permissionless-Software-Foundation/bch-dex-ui) is a [Gatsby](https://www.gatsbyjs.com/) web app and user interface (UI) for bch-dex.
+- [P2WDB](https://github.com/Permissionless-Software-Foundation/ipfs-p2wdb-service) is a censorship-resistant database used to communicate trade data between peers running bch-dex.
+- [IPFS](https://ipfs.io/) is a censorship-resistant network for communicating data over the internet.
+- [MongoDB](https://www.mongodb.com/) is a database used by both P2WDB and bch-dex to store and manage local data.
+
+The above software is orchestrated using [Docker](https://www.docker.com/) and Docker Compose. The target operating system is Ubuntu 20+, and the target hardware is amd64 (normal desktop PCs) and the arm64 (Raspberry Pi 4). Trying to operate this software on other operating systems or hardware is possible, but not supported.
+
+The Raspberry Pi 4 is the primary hardware target, because this software functions best when it is always running. The Pi 4 makes a great appliance for monitoring trade signals and finalizing trades.
+
+Instructions for setting up Node.js, Docker, and Docker Compose can be found in [this Gist](https://gist.github.com/christroutner/a39f656850dc022b60f25c9663dd1cdd). Walk-through videos can also be found on the [PSF Videos page](https://psfoundation.cash/video/).
+
+Here are the steps involved in setting up bch-dex:
+
+1. Follow the direction in [this Gist](https://gist.github.com/christroutner/a39f656850dc022b60f25c9663dd1cdd) to install Node.js, Docker, and Docker Compose.
+1. Clone the repository with `git clone https://github.com/Permissionless-Software-Foundation/bch-dex` and enter it with `cd bch-dex`.
+1. Install dependencies by running `npm install`
+1. Create a wallet:
+  - `cd production/scripts`
+  - `node create-wallet.js`
+1. Change directory to the `production/docker` or `production/rpi-docker` folder depending on your hardware target.
+1. Pull the Docker images down from Docker Hub: `docker-compose pull`
+1. Start the Docker containers with `docker-compose up -d`
+1. Wait for the P2WDB to sync and populate bch-dex with trade data. You can monitor it with `docker logs --tail 20 -f p2wdb`.
+1. Open a web browser and navigate the `http://localhost:4500`. You'll be able to see new Offers as they come in and are detected by bch-dex.
+1. To take the other side of the trade, click the `Take` button in the UI.
+1. You can add the 12-word mnemonic from the `wallet.json` file to the the web wallet, which will mirror your wallet in the UI, and allow you to perform basic wallet functions (send and receive BCH and tokens).
+
+## Blockchain Infrastructure
+
+The P2WDB and bch-dex containers requires a 'Global Back End' (as described in [CashStack.info](https://cashstack.info)) in order to connect to the blockchain. By default, the Docker containers connect to [free-bch.fullstack.cash](https://free-bch.fullstack.cash/). Several community-provided Global Back End servers are provided and can be [viewed here](https://gist.github.com/christroutner/63c5513782181f8b8ea3eb89f7cadeb6). The back end can be changed by setting the `CONSUMER_URL` environment variable in the `docker-compose.yml` file.
+
+### Applying Software Updates
+As this is an active project, software updates will happen frequently. To apply a software update, perform these steps.
+
+
+1. Enter the `docker` or `rpi-docker` folder, depending on your hardware target.
+1. Bring down the Docker containers with `docker-compose down`.
+1. Pull in the software updates with `git pull`
+1. Update dependencies with `npm install`
+1. Pull new Docker images with `docker-compose pull`
+1. Clean up disk space by deleting old Docker images with `./cleanup-images.sh`
+1. Start the Docker containers with `docker-compose up -d`
+
+
+Sometimes it may be necessary to delete the databases before applying a software update. This can be done by stopping the Docker containers and deleting the `production/data` directory. When the Docker containers are restarted, they will recreate that directory. The P2WDB will re-sync and bch-dex will be populated with fresh trade data.

- _Client_ could be a web browser, or a command-line client like [psf-bch-wallet](https://github.com/Permissionless-Software-Foundation/psf-bch-wallet) or [psf-avax-wallet](https://github.com/Permissionless-Software-Foundation/psf-avax-wallet).
- [ipfs-swap-service](https://github.com/christroutner/ipfs-swap-service) is the back end REST API that maintains a local database of information that the client reads from.
+- _Client_ could be a web browser like [wallet.fullstack.cash](https://bchn-wallet.fullstack.cash), or a command-line client like [psf-bch-wallet](https://github.com/Permissionless-Software-Foundation/psf-bch-wallet) or [psf-avax-wallet](https://github.com/Permissionless-Software-Foundation/psf-avax-wallet).
+- [bch-dex](https://github.com/Permissionless-Software-Foundation/bch-dex) is the back end REST API that maintains a local database of information that the client reads from.
 - [P2WDB](https://github.com/Permissionless-Software-Foundation/ipfs-p2wdb-service) is the pay-to-write global database with a REST API for interfacing with the other two pieces of software.

 The arrows in the image represent the information flow between the three pieces of software:

- The _Client_ displays information about orders. It _reads_ this information from ipfs-swap-service.
- The _Client_ is also a wallet. It can generate the needed transactions to _write_ information to the P2WDB.
- `ipfs-swap-service` imports data from the global P2WDB database into its local database, using a [webhook](https://en.wikipedia.org/wiki/Webhook) (dashed line). It can also custody funds by creating an _Offer_ and submitting the data to the P2WDB to generate an _Order_ (solid line).
+- The _Client_ is essentially a 'dummy terminal' with a bidirectional interface to bch-dex. bch-dex does the heavy lifting, and the _Client_ is a 'thin' UI wrapper.

-This architecture keeps the global database highly censorship resistant, while allowing local installations to maintain tight control over the user experience. The goal is to have many redundant copies of `ipfs-swap-service` on the network, and to empower individual traders to run their own, private copy.

+
+# Definitions
+
+The workflow of a token trade has three parts:
+1. **Make** - An *Offer* to buy or sell tokens is generated by a user, known as the *Maker*.
+2. **Take** - A second user, known as a *Taker*, will *take* the *Offer* by issuing a *Counter Offer*
+3. **Accept** - The original *Maker* checks the *Counter Offer* and *Accepts* it by signing and then broadcasting the transaction.
+
+Trades done in this way are both *trustless* and *atomic*:
+- **Trustless** - This means that neither party needs to trust the other. The *Maker* gets to review the *Counter Offer* before broadcasting it. The *Maker* can not alter the *Counter Offer* after the *Taker* has signed it.
+- **Atomic** - The trade happens in a single transaction. There is no middle-state where the trade can get stuck. It either happens or doesn't, it's state is binary and atomic.
+
+Specific *Entities* are defined in the [specification](./specification.md), but here is a brief summary:
+- **Order** represents the *Maker* side of the trade. This entity is internal to `bch-dex`. It is used to track tokens set aside for sale and managed by the wallet controlled by `bch-dex`.
+- **Offer** contains most of the same information as an **Order**, but is external to `bch-dex`. This is data submitted to the P2WDB and visible to all users on the network.
+- **Counter Offer** is generated by a *Taker*, in order to take the other side of the trade. It contains a partially-signed transaction, ready for review by the *Maker*.

-## Writing to the Global Database
+## Reading from the Local Database

-Adding data to the global P2WDB is a result of the interaction between the _Client_ and the P2WDB. Ideally, `ipfs-swap-service` is not involved. The [p2wdb npm library](https://www.npmjs.com/package/p2wdb) can be leveraged for easy reading and writing to the P2WDB.
+The *Client* reads data from the local database stored by `bch-dex`, and does not read the P2WDB global database directly. This gives `bch-dex` the opportunity to filter and modify the data locally, for a more controlled user experience.

-During development, `ipfs-swap-service` is being used to submit Offers to the P2WDB and custody funds. When the project reaches maturity, these functions may be removed, and they should be handled by the Client, so that legal issues around custody of funds are not a problem.
+## Making an Offer
+
+Adding data to the global P2WDB is triggered by the _Client_ calling a REST API endpoint on `bch-dex`. The [p2wdb npm library](https://www.npmjs.com/package/p2wdb) can be leveraged for easy reading and writing to the P2WDB.

 Writing data follows these steps:

- A user submits data to the POST `/offer` REST API endpoint. This will move the funds a segregated UTXO and submit the data to the P2WDB to convert the Offer to an Order. Offers are tracked by the local instance of `ipfs-swap-service`, but Orders are tracked by all instances of `ipfs-swap-service`.
- The P2WDB REST API will then evaluate the data and attempt to update the p2p database using the TXID.
- Each peer on the network will independently validate the new database entry.
- `ipfs-swap-service` will receive a webhook call to its POST `/order` endpoint. This event will trigger the import of the new data into the apps local Mongo database, and generate a new Order model.
+- Tokens and BCH are held by a wallet which is under the controlled of `bch-dex`.
+- The _Client_ submits data to the POST `/order` REST API endpoint to create a new Order.
+- `bch-dex` will move the funds into a segregated UTXO, and will use that UTXO to create an Order. The Order data is written to the P2WDB. The Order data is also saved to the local MongoDB.
+- After submitting the data to the P2WDB, `bch-dex` will receive a webhook call to its POST `/p2wdb` endpoint by the P2WDB. This event will trigger the import of the new data into the apps local Mongo database, and generate a new Offer model.
+- This webhook event is mirrored by every instance of `bch-dex` on the network. Each P2WDB peer on the network will independently validate the new database entry and create a new Offer model.

-## Reading from the Local Database
+## Taking an Offer

-The Client reads data from the local database stored by `ipfs-swap-service`, and does not read the global database directly. This gives `ipfs-swap-service` the opportunity to filter and modify the data locally for a more controlled user experience.
+Users can browse the Offers tracked by a local `bch-dex` by using a *Client*. When they find an Offer they want to to take, they'll use some UI element that will send data to the POST `/offer/take` REST API endpoint. These series of steps happen:
+
+- The `bch-dex` checks to see if the wallet it controls has enough BCH to take the other side of the Offer. If it does, the funds for the offer are moved to a segregated UTXO.
+- The new UTXO is used to generate a *Counter Offer*, which contains a partially signed transaction saved as a hex string.
+- The *Counter Offer* is uploaded to the P2WDB. This triggers a webhook event in every running instance of `bch-dex` on the network.
+- When the webhook is triggered, `bch-dex` will check to see if the *Counter Offer* matches an *Order* under its control. If a match is found, it will trigger an *Accept* event.
+
+## Accepting a Counter Offer
+
+This part of the process is automated and does not require input from the user.
+
+- When a *Counter Offer* is received that matches an *Order* tracked by the local copy of `bch-dex`, it will trigger the *Acceptance* phase.
+- In the *Acceptance* phase, the transaction will be checked to see if it matches the conditions in the original *Order*. If all checks pass, `bch-dex` will sign the transaction and broadcast it, completing the trade.
+- A 'garbage collection' function that runs periodically will delete Orders and Offers in bch-dex that have had their UTXO spent, automatically cleaning up stale trade data that is no longer valid.
+
+## Maintenance
+
+Occasional maintenance functions will be called by an interval timer. The primary purpose of these functions is to check the UTXOs in the Order, Offer, and Counter Offer entities. If any of these UTXOs are spent, the entity is deleted from the local Mongo database.

+  - _p2wdbHash_ - The CID used to identify the order entry in the P2WDB.
+  - _offerStatus_ - The state of the offer. When the data is added to the P2WDB, it gets a value of 'posted', but the database model internal to bch-dex can have the following properties:
+    - *posted* - The offer is posted and can be countered by a taker.
+    - *taken* - The offer was countered and accepted.
+    - *dead* - The UTXO was spent outside the trade, which automatically makes the offer dead.

+- Added properties to P2WDB data:
+  - *dataType* - Has a value of 'offer'. This is used to route the data correctly when the P2WDB webhook passes the data to `bch-dex`.
+
+### Counter Offer
+
+A Counter Offer is the other side of the trade, a mirror image to an Offer. It contains a partially signed transaction, created by the Taker. The Maker will review the Counter Offer before accepting and finalizing the trade.
+
+Counter Offers are not tracked via database models like Offers and Orders are. They are processed by `bch-dex` as soon as they are received. A garbage collection function will be called periodically, to sweep the segregated UTXOs used to generate a Counter Offer back into the root address of the wallet, if it is not accepted after a period of time.
+
+To generate a Counter Offer, a segregated UTXO is created that matches the requirements in the Offer. A partially signed transaction is created that includes the Offer UTXO and the Counter Offer UTXO. The Taker signs the input consuming the Counter Offer UTXO. The partially signed transaction and other trade data is uploaded to P2WDB.
+
+When the Counter Offer data is uploaded to the P2WDB, the data must have the following properties:
+
+- *partialTxHex* - A hexidecimal representation of the partially-signed transaction, which includes the UTXO in the Offer and a second UTXO for that matches the conditions in the Offer.
+- *dataType* - Must have a value of `counter-offer`

-1 An instance of go-ipfs.
-2 An instance of MongoDB.
-3 The JavaScript software in this repository.

-The software in this repository depends on the first two containers, so if they aren't running correctly, the application won't run correctly either.

-## IPFS
-
-IPFS can be a little tricky to set up. By default, the container uses the following ports:
-
- 4001 for TCP connections, exposed publicly.
- 5001 for control by the application, exposed privately.
- 8080 for an IPFS gateway, consumed by the application, exposed privately.
-
-If you already have an IPFS node running on a the computer, you will need to change the ports to avaid a conflict. To change the ports from the default, you'll need to perform a series of steps, and the order of the steps matter.

-1. Edit the `docker-compose.yml` file and change the ports. Then save the file. Here is an example:
-
-```
-ports:
-  - 4101:4101
-  - 172.17.0.1:5101:5101
-  - 172.17.0.1:8180:8180
-```
-
-2. Bring the Docker containers up, and then back down. This will allow the IPFS container to create the config file that you'll need to edit.
-
- `docker-compose up -d`
- Wait a few seconds.
- `docker-compose down`
-
-3. Update the generated config file at `../data/go-ipfs/data/config`, to update the ports in the config file, like this:
-
-```
-"Addresses": {
-    "API": "/ip4/0.0.0.0/tcp/5101",
-    "Announce": [],
-    "AppendAnnounce": [],
-    "Gateway": "/ip4/0.0.0.0/tcp/8180",
-    "NoAnnounce": [],
-    "Swarm": [
-      "/ip4/0.0.0.0/tcp/4101",
-      "/ip6/::/tcp/4101",
-      "/ip4/0.0.0.0/udp/4101/quic",
-      "/ip6/::/udp/4101/quic"
-    ]
-  },
-
-```
-
-4. Update the port changes in the `start-production.sh` shell script. This tells the application which ports to use, in order to control the IPFS node, are are used when signaling other nodes.
-
-5. Quickly rebuild the containers, to add the modified `start-production.sh` shell script to the application Docker container:
-
- `docker-compose build`
-
-6. Now start the containers, and the port changes to IPFS should be complete.
