2018 in review – Focus on Xamarin, RIP UniShare, the rise of crypto and blockchain

This year, I had some rough time to keep me motivated on writing blog posts. In the early months, I was keeping my target to write about Xamarin Forms and my implementations, but I slowly lost pace around the summer.

Xamarin posts

Within the first half of the year, I was keeping a pretty constant 2 week frame for new blog posts, targeting Xamarin and Xamarin Forms. I touched several topics (some of which may be obsolete since Xamarin Forms 3.x). Here is a short recap:

The rise of crypto and blockchain

Since 2017, I was loosely following the area of crypto currencies and blockchain. This year, however, marks the beginning of a deeper dive into the blockchain area – and of course also into crypto currencies. I am not advising anyone to invest any money into crypto currencies, but there are certain projects out there that are really interesting. Two of them are social networks, similar to Tumblr: Steemit and Trybe. While Steemit is running on its own blockchain, Trybe is utilizing the EOS blockchain. Sadly, the .NET world seems to be widely ignored, so I stepped down a bit from posting on those two. I also tested several other networks running on or with blockchain, but none of them took me like the two mentioned above. If you want to learn more about the crypto currencies/projects I am interested in, just head over to my crypto page.

Open Source

Even if I did not made a lot of sound around it, I have worked on some libraries this year. I am not going into detail on every one, just head over to my Github:

I am currently working on another library (targetting crypto payments) – I will write about it once it is ready to be used in your projects.

RIP UniShare

One of the sadest moments this year was the death of UniShare, my most popular Windows (Phone) app. Long story short, due to some changes Facebook made to their API, I had to take UniShare to its funeral at the end of October. Read more about it here.

Looking forward to 2019

In 2019, I will continue my journey within the crypto/blockchain world. Like I wrote above, I am working on a crypto related project at the moment, which I hope to have ready in the early weeks of 2019. One of my other projects, WindowsUnited, will be taken over by another developer in 2019 (because he can invest more time into their official apps and work form them more ore less exclusively). This will free up some recsources, which I am trying to invest in my other projects and the rise of my blogging pace (again).

Thanks to all of you for reading my posts this year. I hope you’ll be with me in 2019 as well. I wish all of you a good arrival in 2019 and a happy new year once it arrives.

Until the next post, happy coding, everyone!

Introducing Coinpaprika and announcing C# API Client

Introducing Coinpaprika and announcing C# API Client

As I am diving deeper and deeper into the world of cryptocurrencies, I am exploring quite some interesting products. One of them is Coinpaprika, a market research site with some extensive information on every coin they have listed.

What is Coinpaprika?

In the world of cryptocurrencies, there are several things one needs to discover before investing. Starting with information on the project and its digital currencies, the persons behind a project as well as their current value and its price, there is a lot of data to walk through before investing. Several sites out there are providing aggregated information, and even provide APIs for us developers. However, most of them are

  •  extremely rate limited
  •  freemium with a complex pricing model
  •  slow

Why Coinpaprika?

A lot of services that provide aggregated data rely on data of the big players like CoinMarketCap. Coinpaprika, however, has a different strategy. They are pulling their data from a whopping number of 176 exchanges into their own databases, without any proxy. They have their own valuation system and a very fast refreshing rate (16 000 price updates per minute). If you have some time and want to compare how prices match up with their competition, Coinpaprika even implemented a metrics page for you. In my personal experience, their data is more reliable average to those values I see on those exchanges I deal with (Binance, Coinbase, BitPanda, Changelly, Shapeshift).

Coinpaprika API and Clients

Early last week, I discovered Coinpaprika on Steemit. They announced their API is now available to the general public along with clients for PHP, GO, Swift and NodeJS. Coinpaprika has also a WordPress plugin and an embeddable widget (on a coin’s detail page) that allows you to easily show price information on your website. After discovering their site, I got in contact with them to discuss a possible C# implementation for several reasons:

  •  very generous rate limits (25 920 00 requests per month, others are around 6 000 to 10 000), which enables very different implementation scenarios
  •  their API is fast like hell
  •  their independence from third parties besides exchanges
  •  their very catchy name (just being honest)

A few days later, I was able to discuss the publication of the C# API client implementation I wrote with them. I am happy to announce that you can now download the C# API Client from Nuget or fork it from my Github repository. They will also link to it from their official API repository soon. The readme-file on Github serves as documentation as well and shows how to easily integrate their data into your .NET apps. The library itself is written in .NET Standard 2.0. If there is the need to target lower versions, feel free to open a pull request on Github. The Github repo contains also a console tester application.

Conclusion

If you need reliable market data and information on the different projects behind all those cryptocurrencies, you should evaluate Coinpaprika. They aggregate their data without any third party involved and provide an easy to use and blazing fast API. I hope my contribution in form of the C# API client will be helpful for some of you out there.

If you like their product as much as I do, follow them:
