UMI-based card game: proudly presenting our first GameFi product!

Fellow blockchain enthusiasts, please welcome a truly unique product in our DeFi universe — the UMI Jack card game. It uses the same principle as the world-famous Blackjack, but players are paired not with a dealer but with other players, like in the also-popular Twenty-One.

UMI Jack functions on top of the UMI decentralized blockchain, which enables the following advantages for the players:

Complete transparency and security. All the game operations are transactions in the UMI blockchain. This means that any player can easily check that all the game rules are strictly followed by monitoring the respective blockchain operations thanks to the transparency of UMI.

Fairness. The inherent transparency also lets anyone see which cards any of the players had when the game ends. The algorithm allows these data to be published openly.

High performance. The ultra-high throughput of UMI and complete absence of fees have made it possible to create a genuinely innovative blockchain-based product. Moreover, the UMI OneApp platform itself does not impose any fees as well.

A new way to obtain UMI. Since UMI Jack is based on the UMI blockchain, the UMI coin is organically used as the in-game currency. Play, win, and get your prizes in UMI!

As UMI Jack becomes more and more popular, the demand for UMI will also grow since the beginners wishing to try their luck in it will need to buy the coin.

Make sure to be one of the first to play, challenge your friends, choose your opponents, and start winning to get your UMI prizes! Get to the top of the leaderboard!

UMI Jack (based on the UMI blockchain) — https://app.umi.top/gamefi/umi-jack.

P.S. This is just the first release: the development of UMI Jack will continue, so the game will continuously improve and new features will be added. Best of luck!

New answers to your questions

We greatly respect our community; therefore, we want to answer the questions you are most concerned about right now. We have compiled a list of questions from the chats and, idle talk aside, here are the answers.

1. You used to say that UMI bought from the wall return to the wall again. Why then is the wall shrinking?

To keep the wall from shrinking, we need to sell UMI bought from the wall for bitcoins, and return the received BTC back to the wall. That is, the procedure should be as follows:

- A UMI buy wall is created — and users use it to sell coins;
- The UMI coins bought by the wall holders are sold for BTC at a higher price;
- The received BTC are returned to the UMI buy wall at the wall price.

This is exactly what we did before when we set up the first buy wall in the first year of UMI development.

But the wall that exists now is completely different — it’s the second wall which we have nothing to do with. Last summer, during the panic sale, our former partners bought the entire wall from us. That is, they sold their UMI and received all BTC from this wall. Not to push the price down, we did not offer all the UMI coins we bought for sale at a higher price.

After the situation stabilized, our former partners set up the second UMI buy wall using these bitcoins at on SIGEN.pro where UMI is now sold at 0.00000035 BTC per coin. As far as we know, the price was calculated in such a way that all UMI in circulation could be bought. After that, our former partners closed down and left the market. Even though they did not take away the bitcoins from the wall on SIGEN.pro, they also stopped managing the wall, according to their news about the closure. As far as we know, when selling UMI to the wall, they can easily withdraw these bitcoins from the exchange. It means that the wall is real, but we have nothing to do with it. It shrinks for a simple reason — users sell UMI using the wall and take bitcoins for themselves.

2. Will the wall keep UMI from falling below 1 ruble?

UMI is an international project that has nothing to do with rubles or any other national currency. In the previous answer, we already mentioned that the UMI buy wall was set up by our former partners so that all UMI coins in circulation could be bought for BTC. And the UMI team has nothing to do with this wall.

3. Why don’t developers launch a service to exchange fiat money for stablecoins linked to fiat currencies or gold? Stablecoins can be launched on the UMI network. For example, UMIG is a gold-bound stablecoin, UMIT is a dollar-bound asset.

Since these are two separate questions, we will answer each of them.

We plan to launch a service for exchanging fiat currencies for crypto assets within UMI OneApp. In our Manifest, we told you about U-DEXP2P — a decentralized peer-to-peer platform for exchanging cryptocurrencies and tokens for fiat currencies and vice versa. It will use a smart contract to protect the interests of both the buyer and the seller.

Read more about this service in our Manifest —https://umi.top/OneApp_en.pdf

As for the stablecoins in the UMI network, we also plan to launch them. But we’re still working on the implementation options. Stablecoins can be different. For example, we can create backed stablecoins (such as USDT or USDC) or algorithmic stablecoins (for example, UST). If we create backed stablecoins, then we need to work out the issue of storing stablecoins backing. For example, to create UMIG, we first need to resolve the issue of purchasing and storing gold. Since we support the idea of full decentralization, it is not so easy to do this.

There are also options to issue tokens of other stablecoins in the UMI network. For example, USDT or UST. We can create bridges to transfer them between different networks. Thus, in the UMI network, it will be possible to tokenize any crypto asset from other networks, including stablecoins, to then transfer it within the UMI network at instant speed with zero transaction commissions. If necessary, this asset can be transferred back from the UMI network to another network.

In general, the issue of adding stablecoins to the UMI network and UMI OneApp is an interesting one and we’re actively working it out. As UMI OneApp develops, we will definitely develop this area. Follow our social media accounts to learn news firsthand.

4. After UMI OneApp is released, will the platform somehow develop to contribute to the growth of the UMI price?

Of course! We are making every effort to further develop the UMI OneApp DeFi platform. After the release of the first beta version, we have already presented:

- End-to-end authorization for UMI Wallet and UMI OneApp for more convenient and secure interaction with the DeFi ecosystem;
- UMI Wallet browser wallet in Google Chrome for quick connection to UMI OneApp via browser;
- The UMI Jack card game based on the UMI blockchain.

We are also nearing the finish line for the launch of NFT in the UMI network.

All this attracts users to the DeFi platform and creates demand for UMI. In the future, there will be a lot more awesome DeFi products; in some, UMI purchase, storage or burning will be mandatory. This may have a positive impact on UMI pricing and shortage. We believe that our qualitative development will allow us to achieve a positive change in the value of our coin.

We would also like to note that after new UMI OneApp updates are released and the DeFi platform is improved, we plan to launch a large-scale advertising campaign to attract a larger audience of crypto users from around the world.

So the large-scale development of UMI and UMI OneApp is still ahead of us!

5. Will UMI be listed on well-known and large exchanges if UMI OneApp has a positive impact on the coin?

Listing on new exchanges, including large ones, has been planned and included in our strategic development concept. The development of UMI OneApp will help us because the coin can become more well-known and popular.

At the same time, we are now more focused on the development of various DeFi areas (including DEX) because they ensure true decentralization and independence from various centralized structures. We can see how the entire crypto world is moving in the same direction, and we fully support it.

6. Will there be a possibility to shorten addresses in the UMI network in the future? For example, could there be something like a umi-nickname instead of a long and hard-to-remember address?

Yes. We have planned to develop the alias functionality, as we indicated in the Manifest. This solution will be presented in our DeFi universe within U-SideChain — the second layer on top of the main UMI blockchain (sidechain) for the integration of aliases, comments on transactions and other features. More specifically, alias is a short, easy-to-remember unique name that can be specified instead of a long and complex public address. For example, you can use your e-mail as an alias and actually receive cryptocurrency transfers “by email”.

That’s all for today. If you have some urgent question and you haven’t received an answer to it, don’t worry. We monitor what happens in our community and will definitely cover the most important issues that concern our audience.

Since comments in our Telegram channel are now open, as in many other social networks, you can safely ask new questions right there. We will select the most frequent, urgent and interesting questions to answer them in one of our future articles.

Love, UMI Team!

What challenges do UMI developers face?

“If a user has to click more than one button to start working with a product, they won’t want to do it”

Dear friends, we have always tried and continue to try to create products that will be the most high-tech, easy-to-understand, secure and user-friendly for any user. In today’s article, we want to share with you the problems that we, UMI developers, face, as well as solutions we find. After all, you only see the final product — an app that is convenient to interact with on a smartphone or computer. However, “under the hood”, this app has a complex infrastructure with a range of solutions.

Today, we will tell you about the path the ready-to-use program code has to go before our users can start using it. It seems obvious that a nice and operating code is not enough to create a convenient product. We need to assemble and package the program in such a way that it is convenient for the user to work with.

A variety of operating systems and architectural platforms

There are a huge number of operating systems based on various architectural platforms, but it does not make any sense to try and create solutions for all of them at once. It would be more logical to target the most popular systems when creating an app.

Historically, three operating systems have become the most popular: Windows, Linux and macOS. However, they can be run on different hardware which is why a new variable appears — the processor architecture.

Previously, the mostly used processors included i386 (IA-32, 32-bit) and AMD64 (x86-64, 64-bit). However, as various mobile devices became more popular, active development of the ARM architecture platforms began, which also took the path of improvement from 32-bit to 64-bit version.

For the user, there’s just one difference between the 32-bit and 64-bit versions — the latter allows for the use of more than 4 GB of RAM with no particular difficulties. Since we knew that the UMI network could process a huge amount of transactions, we realized that network nodes would consume more memory. Accordingly, running a node with a small amount of addressable memory makes no sense in the long term.

Based on the above, we decided to support 64-bit architectures only. In practice, this means supporting four operating systems and corresponding processor architectures:

- Windows OS and AMD64 processor architecture;
- Linux OS and ARM64 processor architecture;
- Linux OS and AMD64;
- Two options for Apple devices that can be combined into one: Darwin operating system and ARM64 processor architecture (for M1 processors) or AMD64 processor architecture (for Intel processors).

We have managed to get rid of external dependencies which streamlines the assembly of the software core — the Go (golang) compiler is all we need.

However, the difficulties are still there because we need to pack the app into a package. Let’s consider a solution to this problem using Linux OS as an example.

There are a huge number of Linux distribution kits. They mainly differ by the set of libraries included in the distribution kit. This is where difficulties arise. For example, if you build an app with dependencies for CentOS 5, it may not work on a more recent release due to the different version of the libraries the app depends on.

Therefore, we are building the UMI app with no dynamic dependencies, that is, it does not depend on the environment it is launched in, at all.

It may seem it has solved our problem — we just need to download or compile a binary UMI file from the source files and run it. But it’s actually a little more complicated than that. In fact, our entire architecture was initially built around the Kubernetes open source software. Therefore, we used Docker as a packaging tool. We assembled Docker images for the AMD64 platform, and it all worked just fine. Docker was also good in a local environment.

However, a different Docker version for the new Apple M1 platform has recently been released, so we had to assemble two versions of the package — for AMD64 and ARM64. At first, it went smoothly thanks to buildx, an experimental Docker functionality. But following transition to the binary blockchain, we had to abandon Kubernetes because we had new requirements for the speed of the disk subsystem. Since we use Amazon Linux 2 based on the RHEL distribution kit to run virtual machines in the Amazon cloud, we decided to try using Advanced Packaging Tool (APT), a regular package manager, and RPM.

Initially, we had no problems with assembling RPM packages using Docker for the AMD64 platform. Later, while optimizing the server architecture cost, we tried using AWS instances on the ARM64 platform. To do this, we had to assemble RPM packages for the ARM64 architecture. Buildx handled the task perfectly well.

At around the same time, the UMI community asked us to add support for the Yum package manager used in Debian and Ubuntu. We delivered. As a result, we now have our own package repository — https://pkg.umi.top/.

So, while preparing each release, we assembled three versions of Linux packages — each package designed for two architectures. In total, it means six stages of development, if we leave out the pipelines for updates and repositories synchronization.

Later we ran into some issues:

- After each update of macOS (used by our developers as the main OS), the programs we used worked worse and worse.
- After another Android Studio update, the network stopped working in the Android emulator;
- We had some problems with network operation in VirtualBox which we actively used to test network interaction.

Working in such conditions became more and more difficult — we had to spend more and more time on repairing the tools rather than on the work itself. When we say ‘tools’, we mean compilers (packagers) we use to prepare products for release.

We decided to try the option with a test environment based on Google Cloud and created a new account to do this. In practice, however, it turned out that this has no major advantages, so we abandoned this idea.

Step by step, we came to the option with an ESXi hypervisor running on a local computer. We liked this option the most, so we just settled on it. But then, we still had the problem of assembling packages for different architectures. The most logical option would be to run separate servers to assemble packages for the target architecture. This would mean maximum efficiency with a relatively small increase in infrastructure costs.

But the recent instability in the world has forced us to reconsider the idea of using “foreign” servers for critical services. Therefore, we started looking for a solution that would allow us to solve the problems with assembling all the necessary packages and updating repositories within one local server. This solution would have to be easily reproducible in the event we need to move all the components to another environment.

As a result, GoReleaser became the solution of our choice. The first impression was quite good. We are now gradually transferring assembly lines to this tool. As we work, we carefully review and test everything; we also have to tackle with multiple peculiar things. It takes a lot of time, but so far this approach seems the most rewarding.

Dear friends, as you can see, the development of complex blockchain products is a time-consuming process most users don’t even notice. We are constantly facing new challenges and sometimes we spend a lot of resources and creative energy on solving the emerging problems. However, it’s definitely worth it as we want to create the best-of-class product that would be accessible to as many users as possible.

In the future, we will continue to be in close touch with you and publish technical articles to share our experience. We hope it’s been interesting.

Love, UMI Team!

UMI wall: where did it go and what happens next?

Dear friends, the “UMI wall” on SIGEN.pro disappeared this morning, and we’re now receiving questions regarding this. We have no idea where the wall went, what happened and why because we had no control over it (which we mentioned more than once).

The UMI price is currently free floating and the actual demand and supply will demonstrate what the coin is worth now. We’re sure that panic mongers and haters will sell the coin for nothing while true UMI believers will, on the contrary, buy as many coins as possible. We do not know what will happen to the coin price next. But we do know that nothing can stop us on our path to reaching our goals.

Our team will continue developing UMI OneApp. We have a great potential in the development of a DeFi ecosystem, decentralized NFT’s and the GameFi sector. We will soon offer you new games, tournaments and a lot more. Blockchain games + NFT = future, especially considering that it’s a super-fast blockchain with zero commissions.

In near future, you can expect a series of reports on NFT and new interesting products. If you believe in us — stay with us. We believe that the demand for UMI will grow in the future thanks to the products we develop, and it will be based on the genuine interest rather than a speculative wall.

Love, UMI Team!
