*Introduction*
These days, every single living being has heard of Bitcoin. Some of those know that Bitcoin is a cryptocurrency (crypto for short) and, within those, a few know that it runs on top of a technology called Blockchain. This technology has boomed just alongside Bitcoin since the year 2008, and it is being used in many different sectors of society (having numerous examples worldwide): finance, industry, healthcare, government. It has existed for some years now, and there are many different blockchains. For crypto, their role is to provide a *descentralized* framework upon which one can execute monetary transactions in a *verifiable*, *irreversible* manner. But some of those blockchains provide extra funcionality: something known as a *smart contract*. Basically, a smart contract is some computer code that runs on top of a blockchain (thus, it has cryptography-enabled *credibility*) that enforces some rules to be obeyed by the involved parties. The first blockchain smart contracts were introduced by Ethereum platform. As stated in their website <https://www.ethereum.org/>: *Ethereum is a decentralized platform that runs smart contracts: applications that run exactly as programmed without any possibility of downtime, censorship, fraud or third-party interference. * *These apps run on a custom built blockchain, an enormously powerful shared global infrastructure that can move value around and represent the ownership of property.* In other words, blockchain is a protocol for users to build systems which need to agree on something. And this thing may be just as simple as a monetary transaction, or as complex as a government. *So, having a way to easily interact with this technology can enable a whole new set of applications.* *My proposal is...* to develop a library to supplement or support the development of django applications with blockchain integration. My success indicator is whether I have made it easy for anyone to store and retrieve information on the blockchain inside their Django code. *Prototype* I already have a working prototype <https://github.com/diego-lima/recepcao_django>. It consists of a simple RESTFul API, and it is part of a side project I was working on: a generic architecture where the users can channel some input to a fast or robust machine to do some processing. The RESTful API was right in the middle, connecting the user device and the robust machine. The example I have built goes like this: 1. The user generates a drawn numerical digit through an android/iOS application, and sends it to the Django API along with his/her ethereum wallet address. 2. The Django API verifies whether the user has paid a small fee. This verification is done by checking if the user has sent a certain ETH amount to a smart contract I have designed and launched (in a private network). 3. The users who have paid this fee have their input processed by my machine. I have set up a convolutional neural network which will recognize single handwritten digits in images. The user then receives the processing result. The idea for this architecture is to be modular and easily extendable for any purpose: signal processing, image processing, data crunching... If my proposal is accepted, I will be open to work on it and do my best, and I expect to learn a lot with my mentor. I also expect to hear suggestions on how to lead this proposal to the most useful functionality. *Schedule* Since I already have a working propotype, a good week can be spent on discussing the existing work, the general implementation design and scope. The following weeks will be spent building, writing tests and documenting. The last week should be spent building some working demo. *About me* I'm a computer engineering student in Brazil, and I have 3 (soon to be 4) years of experience working with Django. Some big projects I have worked on are PMAQ <http://pmaq3.lais.ufrn.br/ab/> and SMART <http://smart.telessaude.ufrn.br/>, which are related to health quality data collection (all over the country) and business intelligence. -- You received this message because you are subscribed to the Google Groups "Django developers (Contributions to Django itself)" group.
