-
-<br/>
-
-This repository is a Java skeleton with Spring & PostgreSQL designed for quickly getting started developing an API.
-Check the [Getting Started](#getting-started) for full details.
-
-## Technologies
-
-* [Java 18](https://openjdk.java.net/projects/jdk/18/)
-* [Gradle 7](https://docs.gradle.org/7.0/release-notes.html)
-* [Spring boot](https://spring.io/projects/spring-boot)
-* [Lombok](https://projectlombok.org/)
-* [Junit](https://junit.org/junit5/)
-* [JaCoCo](https://docs.gradle.org/current/userguide/jacoco_plugin.html)
-* [Docker](https://www.docker.com/)
-* [Make](https://www.gnu.org/software/make/manual/make.html)
-
-## Getting Started
-
-Within the [Makefile](Makefile) you can handle the entire flow to get everything up & running:
-
-1. Install `make` on your computer, if you do not already have it.
-2. Start the application: `make up`
-3. Run the application tests: `make test`
-
-As you could see on the [Makefile](Makefile) script and the [Docker-Compose File](docker-compose.yml), the whole API
-is containerized with Docker and the API is using the internal DNS to connect with the PostgreSQL instance.
-
-Go to `http://127.0.0.1:8080/ping` to see that everything is up & running!
-
-## Overview
-
-This skeleton is based on
-a [Clean Architecture](https://blog.cleancoder.com/uncle-bob/2012/08/13/the-clean-architecture.html) approach, so you
-could find the first basic layers:
-
-> You could find here two amazing articles ([here](https://www.educative.io/blog/clean-architecture-tutorial)
-> and [here](https://www.freecodecamp.org/news/modern-clean-architecture/)) explaining the Clean Architecture with Java!
-> (credits to [@bertilMuth](https://twitter.com/BertilMuth) and [@ryanthelin](https://dev.to/ryanthelin)).
-
-### Infrastructure
-
-Here you will find the different files to interact with the outside. In this folder you there are two different folders:
-
-* `controllers`: Here you will have the classes that handle the REST endpoints and the Request/Response
-* `persistence`: Here it is the persistence layer, which interact with the PostgreSQL database, decoupling the rest of
-  the application
-
-You can use this as a starting point to continue with this architecture, or adapt it to your preferences.
-
-### Domain
-
-Any of your domain Entities, or Services, that models your business logic. These classes should be completely isolated
-of any external dependency or framework, but interact with them. This layer should follow the Dependency Inversion
-principle.
-
-## Support
-
-If you are having problems or need anything else, please let us know by
-[raising a new issue](https://github.com/Rviewer-Challenges/skeleton-java-spring-rest/issues/new/choose).

+# CartChain
+
+Proof of concept for an e-commerce API implementing blockchain technology by using a simple private chain (no mining)
+
+## How it works?
+
+The aim of this API is to manage a shopping cart of an ecommerce website. So, through it, the client will be
+able to request and create, update or delete any item in the current cart.
+
+Every action of the API will generate a new _Block_ on the _Blockchain_ in order to create a history and persist the
+information, so we can retrieve it later, but also keeps a history of which items have the user added to the cart.
+
+### Workflow
+
+The workflow of this API is as follows:
+
+* Create
+
+1. Create request is received
+2. Check if the `id` for a Cart is not already used
+    1. If it has been used we return error
+    2. If it has not been used, we create the cart with the given item and generates a new Block to add to the
+       Blockchain
+3. Add the new _Block_ to the _Blockchain_ with the current information of this Cart
+
+* Update
+
+1. Update request is received
+2. Check if the `id` for a Cart exists
+    1. If not exists return error
+    2. If exist retrieve it
+3. Update the items in the cart and generate a new Block with the information
+4. Add the new _Block_ to the _Blockchain_
+
+* Delete
+
+1. Delete request is received
+2. Check if the `id` for a Cart exists
+    1. If not exists return error
+    2. If exist retrieve it
+3. Remove cart information and create a new _Block_
+4. Add the new _Block_ to the _Blockchain_
+
+## Technical Considerations
+
+### Stack
+* [Java 17](https://openjdk.java.net/projects/jdk/17/)
+* [Gradle 7](https://docs.gradle.org/7.0/release-notes.html)
+* [Spring boot](https://spring.io/projects/spring-boot)
+* [Lombok](https://projectlombok.org/)

+* [Make](https://www.gnu.org/software/make/manual/make.html)
+
+### Architecture
+
+This app is implemented using hexagonal architecture (ports & adapters) and DDD approach.
+
+The architecture helps to have a decoupled code and being easy to modify or extend it. Following diagram hints how this is achieved:

+3. Run the application tests: `make test`
+
+Go to [localhost:8080/swagger-ui/index.html](http://localhost:8080/swagger-ui/index.html) to see the API description.
+
+As you can see on the [Makefile](Makefile) script and the [docker-Compose File](docker-compose.yml), the whole API
+is containerized with docker and the API is using the internal DNS to connect with the PostgreSQL instance.

-#   Gradle start up script for POSIX generated by Gradle.
-#
-#   Important for running:
-#
-#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
-#       noncompliant, but you have some other compliant shell such as ksh or
-#       bash, then to run this script, type that shell name before the whole
-#       command line, like:
-#
-#           ksh Gradle
-#
-#       Busybox and similar reduced shells will NOT work, because this script
-#       requires all of these POSIX shell features:
-#         * functions;
-#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
-#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
-#         * compound commands having a testable exit status, especially «case»;
-#         * various built-in commands including «command», «set», and «ulimit».
-#
-#   Important for patching:
-#
-#   (2) This script targets any POSIX shell, so it avoids extensions provided
-#       by Bash, Ksh, etc; in particular arrays are avoided.
-#
-#       The "traditional" practice of packing multiple parameters into a
-#       space-separated string is a well documented source of bugs and security
-#       problems, so this is (mostly) avoided, by progressively accumulating
-#       options in "$@", and eventually passing that to Java.
-#
-#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
-#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
-#       see the in-line comments for details.
-#
-#       There are tweaks for specific operating systems such as AIX, CygWin,
-#       Darwin, MinGW, and NonStop.
-#
-#   (3) This script is generated from the Groovy template
-#       https://github.com/gradle/gradle/blob/master/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
-#       within the Gradle project.

-# Cartfidential
-
-Within the current landscape of digital commerce, there is no such progress and there are still the same problems of
-scalability and performance with high traffic than some years ago. For this reason, we have decided to implement a new
-type of ecommerce based on the [Blockchain](https://builtin.com/blockchain) technology, creating a decentralized network
-to execute and store, in a decentralized way, the different processes of an ecommerce.
-
-That's why you will be in charge of creating a very important part of it, the shopping cart.
-
-## How it works?
-
-The aim of this API is to manage a shopping cart of our ecommerce website. So, through it, the Frontend Team will be
-able to request and create, update or delete any item in the current cart.
-
-Every action of the API will generate a new _Block_ on the _Blockchain_ in order to create a history and persist the
-information, so we can retrieve it later, but also keeps a history of which items have the user added to the cart.
-
-You could find the API description on the OpenAPI description file.
-
-### Workflow
-
-The workflow of this API is as follows:
-
-* Create
-
-1. Create request is received
-2. Check if the `id` for a Cart is not already used
-    1. If it has been used we return error
-    2. If it has not been used, we create the cart with the given item and generates a new Block to add to the
-       Blockchain
-3. Add the new _Block_ to the _Blockchain_ with the current information of this Cart
-
-* Update
-
-1. Update request is received
-2. Check if the `id` for a Cart exists
-    1. If not exists return error
-    2. If exist retrieve it
-3. Update the items in the cart and generate a new Block with the information
-4. Add the new _Block_ to the _Blockchain_
-
-* Delete
-
-1. Delete request is received
-2. Check if the `id` for a Cart exists
-    1. If not exists return error
-    2. If exist retrieve it
-3. Remove cart information and create a new _Block_
-4. Add the new _Block_ to the _Blockchain_
-
-## Technical Considerations
-
-Keep in mind the following:
-
-1. Related with the Blockchain:
-    1. The blockchain have a first block called 'genesis block', these block doesn't contain a reference of the previous
-       block, usually is hardcoded on the software
-    2. Every Block has multiple properties:
-        1. timestamp: the timestamp for the moment when the block was created
-        2. lastHash: hash of the previous block on the _blockchain_
-        3. data: information we want to store in the block (in our case the votes)
-        4. nonce: a unique number
-        5. hash: a SHA256 string for the block, calculated concatenating the timestamp, lastHash, data and nonce.
-    3. The implementation of the Blockchain must follow these contract:
-        ```
-         Blockchain
-           /** Adds new block to blockchain */
-           addBlock(block: Block): Block
-           /** The new blockchain that is a candidate for replacing the current blockchain */
-           replace(blockchain: Blockchain): boolean
-           /**
-            * Validates the chain by checking if:
-            * - Genesis Block hash match given blockchain genesis block hash
-            * - every element's last hash value matches previous block's hash
-            * - data hasn't been tampered (which will produce a different hash value)
-            */
-           isValid(blockchain: Blockchain): boolean
-      
-         Block
-           /** Generate the first block for the chain */
-           static getGenesisBlock(): Block
-           /** Generate the hash for the given block */
-           static generateHashFromBlock(block: Block): string
-         ```
-
-## Technical requirements
-
-* Create a **clean**, **maintainable** and **well-designed** code. We expect to see a good and clear architecture that
-  allows to add or modify the solution without so much troubles.
-* **Test** your code until you are comfortable with it. We don't expect a 100% of Code Coverage but some tests that
-  helps to have a more stable and confident base code.
-
-To understand how you take decisions during the implementation, **please write a COMMENTS.md** file explaining some of
-the most important parts of the application. You would also be able to defend your code through
-[Rviewer](https://rviewer.io), once you submit your solution.
-
----
-
-## How to submit your solution
-
-* Push your code to the `devel` branch - we encourage you to commit regularly to show your thinking process was.
-* **Create a new Pull Request** to `main` branch & **merge it**.
-
-Once merged you **won't be able to change or add** anything to your solution, so double-check that everything is as
-you expected!
-
-Remember that **there is no countdown**, so take your time and implement a solution that you are proud!
