-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+  - This video is out of date.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.

+- *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`

-Details TBD.

 ## Use Cases

 Use cases are verbs or actions that is done _to_ an Entity or _between_ Entities.

-### Offer
-
- **`createOffer()`** - This method is triggered by a webhook from the P2WDB. It will take the data provided by the P2WDB and create a new Order entity in the local database.
-
 ### Order

+- **`createOrder()`** - A macro command that leverages the other functions in this library to create a new Order and submit it to the P2WDB.
 - **`ensureFunds()`** - Ensure that the wallet has enough BCH and tokens to complete the requested trade.
- **`moveTokens()`** - Move the tokens indicated in the order to a temporary holding address. This will generate the UTXO used in the webhook message. This function moves the funds and returns the UTXO information.
- **`createOrder()`** - A macro command that leverages `ensureFunds()` and `moveTokens()`, to create a new Order and submit it to the P2WDB.
+- **`findOrderByHash()`** - Given a P2WDB CID 'hash', this function will return the corresponding Order model associated with that CID.

-### Counter Offer
+### Offer

-TBD
+- **`createOffer()`** - This method is triggered by a webhook from the P2WDB. It will take the data provided by the P2WDB and create a new Offer entity in the local database.
+- **`listOffers()`** - Returns a list of all the active Offers tracked by `bch-dex`.
+- **`takeOffer()`** - Generate a segregated UTXO and partially signed transaction, then upload the Counter Offer data to the P2WDB.
+- **`ensureFunds()`** - Ensure the wallet has enough BCH and tokens to make a Counter Offer.
+- **`findOfferByHash()`** - Given a P2WDB CID 'hash', this function will return the corresponding Offer model associated with that CID.
+- **`acceptCounterOffer()`** - This function is triggered by the P2WDB webhook REST API handler. When a Counter Offer is passed to `bch-dex` by the P2WDB, the data is then passed to this function. It does due diligence on the Counter Offer, then signs and broadcasts the transaction to accept the Counter Offer.

 ## Controllers

 Controllers are inputs to the system. When a controller is activated, it causes the system to react in some way.

-### Offers
-
- **POST /offer** - This POST REST API endpoint will be triggered by a webhook generated from P2WDB. This will notify the `bch-dex` that a new entry has been added to the P2WDB that matches the `appId` of `swap-<chain>`, where `<chain>` has a value of `avax`, `bch`, or `ecash`. It's a new entry that should be evaluated for inclusion in the `ipfs-swap-service` local database.
-
 ### Orders

- **POST /order** - This POST REST API endpoint can be triggered by the Client or a simple curl call. It passes in the data needed for `bch-dex` to generate and track a new Order, then submit the data to the P2WDB to generate an Offer that is tracked by all other instances of `bch-dex`.
+- **POST /order** - This POST REST API endpoint can be triggered by the Client or a simple curl call. It passes in the data needed for `bch-dex` to generate and track a new Order, then submits the data to the P2WDB to generate an Offer that is tracked by all other instances of `bch-dex` on the network.
+
+### Offers
+
+- **GET /offer/list** - Returns an array of objects, where each object represents an active Offer.
+
+- **POST /offer/take** - Given the P2WDB CID of an Offer, calling this endpoint will attempt to generate a Counter Offer and upload it to the P2WDB.
+
+### P2WDB
+
+- **POST /p2wdb** - This POST REST API endpoint will be called by a webhook generated from the P2WDB. This will notify the `bch-dex` that a new entry has been added to the P2WDB that matches the `appId` of `swap-<chain>`, where `<chain>` has a value of `avax`, `bch`, or `ecash`. It's a new entry that should be evaluated for inclusion in the `bch-dex` local database. Based on the `dataType` property, the data is routed to either create a new Offer or to process a new Counter Offer.

 ## Adapters

-Adapters are output libraries so that the business logic doesn't need to know any specific information about the I/O. They are essentially the output of the application.
+Adapters are outputs. These libraries exist so that the business logic doesn't need to know any specific information about the I/O. They handle the low-level mechanics of the various subsystems.

 - **localdb** - An adapter for the local database (MongoDB).
 - **ipfs** - An adapter for IPFS and the ipfs-coord library. It allows the app to use the JSON-RPC over IPFS.
+- **wallet** - Handles low-level wallet tasks.
+  - **`moveTokens()`** - Move the tokens indicated in the order to a temporary holding address. This will generate the segregated UTXOs used in the trade. This function moves the funds and returns the UTXO information.
+  - **`moveBCH()`** - Same idea as `moveTokens()`, but creates a non-SLP segregated UTXO, used when generating a Counter Offer.
+  - **`openWallet()`** - Opens the JSON file containing the wallet data for the app.
+  - **`instanceWallet()`** - Given the wallet data returned by `openWallet()`, it generates an instance of the [minimal-slp-wallet](https://www.npmjs.com/package/minimal-slp-wallet) for generating UTXOs and interacting with the blockchain.
+  - **`incrementNextAddress()`** - Increments the index of the [HD wallet](https://github.com/bitcoinbook/bitcoinbook/blob/develop/ch05.asciidoc#hd_wallets) used to generate keypairs for storing segregated UTXOs.
+  - **`getKeyPair()`** - Generates a keypair from the HD wallet.
+  - **`generateSignature()`** - Generate a cryptographic signature.
+  - **`generatePartialTx()`** - Create a partial transaction as part of a Counter Offer.
+  - **`deseralizeTx()`** - Used only for debugging purposes. Expands a hex transaction into a JSON object.
+  - **`completeTx()`** - Complete the partially signed transaction by signing the first input, then broadcasting the transaction to the network.

-# Docker Containers
-
-The 'production' environment is assumed to be a set of Docker containers orchestrated with Docker Compose. The files in this directory will stand up three Docker containers:
-
-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.
