Tech-ECHO KW37 – Lightweight Lightning Client, Mimblewimble and Stablecoins

In addition to a Light Client for the Lightning Network, the calendar week 37 was mainly characterized by innovations in the Ethereum network and various stable coins. But also other topics like a patent dispute between Bitmain and Whatsminer or Mimblewimble shaped the week.

In the Bitcoin and Bitcoin Cash environment, all eyes were on the debates between Roger Ver, Jimmy Song and Tone Vays last week. In the Ethereum ecosystem a lot has happened with sharding, a new testnet and token standard. Also with other crypto currencies time did not stand still.

In the IOTA environment the team worked on a solution for the volatility problem, various stable coins came into the limelight and Beam is a new crypto currency with MimbleWimble focused on anonymity. Generally there were patent disputes in the blockchain area and with ASIC Boost a ghost from the past came into the Bitcoin system again.

A Lightning Client for Bitcoin code

This week the development front around Bitcoin code remained relatively quiet, but Lightning Labs was able to reach a milestone: On September 10th Tankred Hase presented the new version of the Lightning App. The special thing about it: The app should run as a light client – even on smartphones. With this app it is no longer necessary to run your own Lightning Full Node. The app is currently connected to the test network. Those who are „in it for the technology“ can download the app and transfer some „play money“ to the Light Client via a faucet (also available for Bitcoin thanks to Lightning).

Bitcoin code: New Milestone in Sharding and the Görli-Testnet

Vlad Zamfir has written a proof of concept for Bitcoin code together with Steve Marx and others. Sharding is a scaling solution for the Ethereum network. Simply put, the approach is that not every node needs to know the entire blockchain, but only a shard:

One can imagine that a secure solution is complicated. The risk of a so-called cross-shart atomicity failure must be excluded. One can imagine this error in such a way that someone sends a payment in one shard but the reception is not registered in another. Such contradictions must not occur in the network and Vlad Zamfir believes that his solution will avoid this error.

Afri Schoedon of Parity is convinced that a new type of Ethereum test net is needed. In the linked article he describes what there are for different publicly accessible test networks – that alone is an interesting overview. What he thinks is missing is a network that allows different clients and is not proof of work.

The Görli-Testnet-Proposal contains three points: First, it invites to elaborate a proof-of-authority mechanism in the form of an Ethereum Improvement Proposal. Proof of Authority is a consensus mechanism in which an authority is trusted to generate the blocks.

Especially for test nets, such a consensus mechanism can be useful for possible troubleshooting, since the identity of the validators is formally verified at least via dApps. Secondly, such mechanisms should be implemented in clients like Geth or Parity Ethereum. Finally, Afri Schoedon wants to set up a complete proof-of-authority testnet with Görli. Ultimately, the ultimate goal is to have a test net in which the various innovations affecting Casper can be tried out in more detail.

Does this mean that your app is not a dApp and does not need any crypto reference?

In my opinion the currently available blockchains are all either too unstable, slow or too expensive to consistently develop FitLeap as a dApp right from the start. That’s why we decided to first build a native iOS and Android app and cover the handling and checking of the health and activity data with the blockchain technology. As described in the introduction, our goal is to establish mass blockchain applications. This requires, for example, that my brother can also use FitLeap. He has no connection to the crypto world. But he goes to the gym three times a week and tracks his data.

If you ask me, this is exactly one of the biggest problems of the scene – no existing mass suitability! That’s why we separate the crypto reference between users and investors.

So what does your business model look like and how do you make Bitcoin profit?

Our Bitcoin profit business model is divided into three areas – the app, the marketplace and B2B. The last two points are exciting. We are developing a marketplace in which FitLeap users can get their favourite products such as sportswear, supplements, etc. at a much lower price than in regular shops based on their activity. I myself have been working in the eCommerce industry for many years and can contribute my full know-how here. But the biggest and at the same time most exciting Bitcoin profit area is B2B. Let’s take the health insurance companies as an example. They are obliged to invest millions every year in prevention, have massive pressure to innovate and spend an average of over 1,000 euros on a new customer.

„Unfortunately“ (or fortunately) they cannot buy health data from other providers due to regulations. But what if every user has his data through FitLeap and can decide for himself whether he wants to make it available for a discount on his monthly health insurance contributions or not?

At this point we only connect the end user with the B2B partner and have no access to the health data at any time. This distinguishes us considerably from established fitness apps.

What makes you so sure that the rather cumbersome and not exactly known for digitization health insurance companies will jump at such innovative solutions?

The public’s impression is perhaps a little deceptive. Not all health insurance companies are cumbersome. Some of them, such as AOK Nordost, have already done amazing pioneering work here. For our so-called Product Market Fit, we have been holding talks with experts and decision-makers from the healthcare industry for hours now as supporters of the lean start-up mindsets. No matter whether it is the private or statutory health insurance, the life insurance or the regulatory side, i.e. the legislation. Our founding team and especially our consultants are extremely well networked here.

What will the next Bitcoin profit steps look like, what will be next at FitLeap?

We are currently working with our team at MVP, with an emphasis on Bitcoin profit. Furthermore, we are currently clarifying the last legal issues around our security token, which we are selling to investors in a seed round. In the coming weeks, our followers will be able to see and admire a lot here. We have set up a group on Facebook to document the development process of FitLeap transparently with weekly live streams.

Master thesis at the RFH Cologne: Success factors of crypto currencies

Alina Ley successfully completed her Master in Business Administration at the Rheinische Fachhochschule Köln with her Master thesis: „Success Factors of Crypto Currencies“. Alina was so kind as to provide us with her most important research results, which are listed in the following in a highly abbreviated form. The team of BTC-ECHO congratulates to the outstanding master thesis (note 1,0) and wishes further success.

Recommendations for action for Bitcoin formula companies

Problem: In 2009 the crypto currency Bitcoin formula revolutionized the existing payment options. There are now well over 500 different crypto currencies.

However, many companies are still sceptical about this topic. Accordingly, companies need to analyse the extent to which they need to take action and the opportunities and risks arising from the use of crypto currencies.

The objective of the Master Thesis is to work out and analyze the success factors of crypto currencies and on this basis to derive recommendations for action for companies.

Research question
Which success factors of crypto currencies can be identified and which possibilities for increasing efficiency with regard to processes, risks and costs result from this for companies?

How to proceed
The central research question and the questions derived from it are examined on the basis of an empirical survey (expert survey). The semi-standardised questionnaire contains 23 questions. The research results obtained are then verified in more detail and linked to existing theoretical knowledge.

The most important Bitcoin trader results

As success factors of Bitcoin trader crypto currencies costs, time, security, decentralization, anonymity, transparency and different application areas can be derived like this:

Crypto currencies are basically suitable for use in different industries and company areas. However, there are differences between acceptance and use in the individual industries. Sectors with a high degree of personal contact as well as public and state institutions are only suitable for successful implementation to a limited extent compared to the financial or insurance sector.

At present, the distribution and acceptance of digital currencies only amounts to a small circle of users. However, more and more companies are dealing with this topic, so that the importance of crypto currencies will continue to increase in the coming years. Companies that recognize the potential of crypto currencies early on have the opportunity to gain advantages over their competitors.

The use of digital currencies can create opportunities to increase efficiency. Faster and more cost-effective transactions make such an increase in efficiency possible. In addition, processes can be automated and administrative costs saved. This enables processes to be optimized and efficiency to be increased at the same time.

The following risks can be reduced by using crypto currencies: Payment default risks, exchange rate risks, 3rd party risks and, depending on the country, currency-specific risks.

Security can be increased by reducing fraud, manipulation and theft. Data security, data protection and protection against counterfeiting can be increased.

However, the technology is still in its infancy and therefore risks can arise. These include in particular the risks due to technical problems and legal certainty. Technical problems can be reduced by continuous improvements to the system. The legal perspective, on the other hand, is far more complex, as it is still unclear at this point how decentralized crypto currencies will be controlled by government institutions in the future and what effects this will have on companies.

In the first step, companies should check their existing business models for validity. The resulting decision provides the basis for the next steps in action.

The implementation of crypto currencies should be more strongly addressed and promoted in the digitization/innovation departments. However, it is rather a strategic core topic, which should also be prioritised as such. At the beginning, comprehensive strategies must be developed in order to be able to implement them afterwards.

Above all, companies should recognize the importance of blockchain technology for themselves. It is the innovative driver behind the crypto currencies and holds a high future potential. Through the use of e.g. Smart Contracts, the company can w

The long-term development of the share price

We see that between May 09th and May 17th the price was in a slight upward channel. This was finally breached upwards. It is good that the MACD is still positive. But beware, the MACD line is still above the signal, but a bearish crossing is imminent. However, the RSI is bullish with 65. Overall, the 240min chart is cautiously optimistic.

Let’s take a closer look at the 1D chart

This shows the upward channel that was mentioned last week. We see that the price has been in this upward channel since March. From time to time the support described by the EMA31 was tested, but it could always hold. According to this Upward Channel the price can fall now if necessary; the resistance of the channel has been tested.

The MACD is positive, additionally the MACD line is above the signal. The RSI is currently at 62 and is therefore bullish as well.

The long-term forecast is bullish according to price, trend and MACD. It will therefore have to be shown more precisely how the price on the EMA24 on the 60min chart behaves. It is also important to see whether the resistance described by the Upward Channel continues to hold.
