Blockchain smartphones: phones with support for cryptocurrencies and blockchain applications



September 10, it became known that the Korean company LG is working on the launch of a smartphone with support for blockchain technology. How many days before this, its main competitor, Samsung, announced the release of its second blockchain phone from the Galaxy line. By the end of this year, several releases of such devices are planned at once, and, the competition involved a variety of companies – from leading manufacturers to startups and even crypto exchanges . What phones can already be bought and which will soon be on sale, understood.

In the mobile device industry, competition for users of decentralized applications and cryptocurrencies is intensifying.

According to the Korean portal Chosun, LG has approved a plan to release a smartphone with support for blockchain functions. The publication added that LG had already conducted market research, and also met with local developers of decentralized applications. And in February this year, the company filed an application with the US Patent Office for the registration of the ThinQ Wallet trademark. Judging by the description, this will be called the future native cryptocurrency wallet from LG with the function of transfers and payments.

LG is no longer new to the crypto industry. Last year, the corporation launched the Monachain blockchain platform. And in July this year, it became known that Monachain will be used to track the supply of meals to South Korean schools. The whole cycle will be monitored – starting from the source of origin of the raw materials and ending with the consumption of products in the educational institution.

LG KlaytnPhone rival: Samsung and Kakao blockchain smartphone

South Korea regularly gets into news feeds, as in this country both business, society and the authorities are actively developing the blockchain industry. The LG initiative is a response to the actions of competitors from among Korean companies, namely, the speedy release of the KlaytnPhone blockchain smartphone. Under this name is the Galaxy Note 10 (in the version with 5G), but with a Keystore wallet and support for BApp (blockchain apps). KlaytnPhone is a joint project of two other Korean corporations – Samsung and Kakao. Both companies have many DLT initiatives. The price of the phone starts at $ 1000.

Samsung is actively investing in startups, building a corporate blockchain platform, the company's blockchain solutions are used in the public sphere. But the company's biggest application is the integration of its own Keystore cryptocurrency wallet in the new Galaxy S10 phone, which sales began in February this year. Samsung was the first leading smartphone manufacturer to introduce cryptocurrencies into its devices.

Recently in Keystore, along with ERC20 standard tokens , bitcoin support has finally been added. Now Samsung is releasing the second blockchain smartphone, and a company representative said that support for cryptocurrencies will be transferred to other, more budget models from the Galaxy line.

Kakao is more focused on software development. The company's flagship business is the most popular KakaoTalk messenger in South Korea. In May, Kakao launched its own blockchain platform, Klaytn. In addition, the company plans to introduce a cryptocurrency wallet and a cryptocurrency transfer service in its messenger, similar to Calibra from Facebook.

HTC and Exodus

Taiwanese HTC was the first company to launch a specialized phone for cryptocurrency holders on the market – HTC Exodus 1 was released at the end of October 2018.

The smartphone with a Qualcomm Snapdragon 845 processor runs on Android Oreo OS, has a 6-inch display and two dual cameras. A feature of the phone is the presence of the Secure Enclave security coprocessor, which allows you to hide personal data from the Android OS.

In addition, Exodus provides a mechanism for recovering private keys from crypto-wallets with the help of a seed phrase shared between several authorized users of the user. If a device is stolen, access to wallets can be restored through the combination of phrases. For private keys, storage and cryptocurrency transactions in Exodus, the Zion application is responsible. User keys are stored in the hardware of the phone for greater security.

Following the release, HTC released several updates for its blockchain phone. So, in the spring, Zion added the function of atomic swaps for currencies of the ERC20 standard stored in the wallet. And on September 16, HTC announced the introduction of the Bitcoin․com crypto wallet with support for Bitcoin Cash .

However, HTC decided not to stop on one blockchain phone and intends to introduce Exodus 1S by the end of the third quarter of this year. It is known that the new device will be noticeably cheaper than its predecessor – its price will be $ 250− $ 300.

In addition, a full node of the Bitcoin network can be installed on the smartphone. As planned by the manufacturer, this will enable users, if they wish, to verify the blockchain data themselves. At the same time, this possibility imposes certain technical requirements for the future smartphone – it should have enough memory for a node with a size of 200 GB, which grows annually by 50-60 GB. And this is not counting the space required for the system and programs.

“We think this is a fundamental [principle] for a decentralized Internet,” said Phil Chen, head of HTC blockchain, “if you don’t own your own keys, you don’t own bitcoins, you don’t own your cryptocurrency.”

Sirin Labs

The Finney device also claims to be the first blockchain phone. This smartphone is the development of startup Sirin Labs. In 2017, he raised about $ 157 million in ICOs for Finney, and device sales began late last year.

The device has a 6-inch screen with a resolution of 2160 × 1080, a 12 MP main camera, 128 GB of internal memory and an SD card slot. For the operation of the device, as in Exodus 1, the Qualcomm Snapdragon 845 processor is responsible. The phone’s feature is a built-in hardware wallet with a separate screen and support for dApps.

The device runs on Sirin OS (Android platform). Finney is sold through the official website for as low as $ 990 (purchase is available with Sirin Labs native tokens). The company also has branded stores in several countries, including the United States, Britain, Thailand and Japan.

In general, Sirin Labs business is developing: in March, the company announced the addition of the popular Ethereum wallet MyEtherWallet to the phone , and just a few days ago it confirmed its intention to open an offline store in Bangladesh. However, in April, Sirin Labs laid off a quarter of its employees because of the “difficult market situation” and announced that it would further focus on research and software development.

BOB: blockchain phone with modules

Another unusual device with blockchain functions was developed by Pundi X, which develops a platform for payments via blockchain . In the winter of 2018, the startup began selling corporate customers its own POS terminal compatible with cryptocurrencies, and according to official figures , it has already sold more than 100,000 units of payment devices. In the autumn of the same year, Pundi X first announced plans to sell its own smartphone and showed its appearance:

The phone has been in development for more than a year, and on September 11, Pundi X introduced new details.

  • Firstly, the final name of the device is BOB (Blok on Blok).
  • Secondly, Pundi X positions BOB as the first smartphone capable of working completely on the blockchain. This will be implemented as follows: the phone will have two modes – in the usual it is just an Android smartphone, and in another mode, the special Function X blockchain will be used. It provides complete privacy, preventing applications from sending user data to third parties. For example, users of two BOBs will be able to send messages to each other through nodes with full encryption of the content.
  • Thirdly, BOB will cost $ 600, crowdfunding campaigners on Kickstarter will be able to get the device, and the initial batch will be only 5,000 phones.

It is curious that it will be possible to attach “modules” to the BOB (included). Apparently, they will only change the appearance without changing the functionality. After attaching all the modules, the BOB will look like this:

It is also known that BOB will run on a Qualcomm Snapdragon 660 processor, and also have a minimum of 6 GB of RAM and 64 GB of physical.

Huobi and Acute Angle

Another newcomer to this segment is the Acute Angle phone, which was created by the Whole Network startup, acquired by the Huobi cryptocurrency exchange . This blockchain phone is perhaps the cheapest among competitors. The retail price of the device will be about $ 515, but it can be significantly reduced if you buy a smartphone for Huobi HT exchange tokens.

It is curious that Huobi is hoping for its community of traders, because it chose a model for distributing the phone through its Prime IEO platform. Those who want to buy a phone will need to take part in a crowdfunding company. Huobi plans to sell no more than 10,000 phones.

Little is known about Acute Angle itself: a 6.7-inch screen, at least 6 GB of RAM and 128 GB of physical memory. In addition, the Huobi trading ecosystem and a certain NODE native loyalty token will be integrated into the phone, which will be used as a reward for certain user actions. In addition, you can separately order a cold NODE wallet, which can be attached to the phone.

Acute Angle sales should begin this week, but so far only in China. In the fourth quarter of this year, the smartphone will be available for purchase in the countries of Southeast Asia, in terms of delivery to the United States and Europe.

Review Summary

Smartphones are the most common type of digital device, so it is not surprising that the blockchain penetrates not only mobile platforms, but also becomes an integral part of the devices themselves. At the very least, phone makers are beginning to take into account the innovations of this technology to increase the security of devices and personal data.

Houbi Global CEO Livio Wang predicts a great future for blockchain phones:

“We think that blockchain phones are a promising area of the crypto industry. As the industry evolves, and innovations such as 5G integrate into our telecommunication systems, we think that the entire crypto community will trade and transfer cryptocurrencies from mobile devices more and more. ”

The possibilities provided by the introduction of the blockchain can be much more than just storing private keys and encrypting personal data. So, the former Coinbase technical director, Balaji Srinivasan, is confident that the deep integration of the blockchain into smartphones will allow to fight against “fraud of the future”, for example, fake calls with requests for transfers when the caller’s voice is generated by the program using AI. Such cases are already happening. To prevent “dipfeyki”, Srinivasan proposed using a two-factor caller identification system, which would use voice recognition technology and cryptographic signature recognition.

Staking and cryptocrediting – which is more profitable than stablecoins or PoS cryptocurrencies?



In this article, we will consider the prospects of cryptocurrency staking as a new way of passive earnings, about the differences between staking and cryptocrediting, as well as about the main platforms designed for this.

If you have not been interested in staking before, then a variety of coins and platforms that support this type of passive income can make you dizzy. And with the advent of stablecoins, the choice has become even wider. What type of coins is better in terms of profit and risk?

Cryptocurrency Staking in 2020

A year ago, cryptocurrency staking was much simpler than now. The cryptocurrency market was attended by only a few specialized platforms, a pair of popular cryptocurrencies and approximately the same rate of return.

But these times have passed: in 2020, staking has grown into a serious segment of the crypto industry for several reasons.

  • Firstly, the market now has more than 30 PoS coins that support the possibility of staking.
  • Secondly, many kriptobirzh now there own PoS-nodes – an interesting alternative to special steykingovym platforms.

Moreover, now investors are provided with staking and deposit accounts in stablecoins, which allow minimizing risk and getting profitability at the level of PoS-coins or even higher. What to choose?

To find out, you need to compare the two main options on the market (PoS coins and stablecoins), according to a number of clear criteria. However, an important reservation must first be made about the nature of staking.

Staking and cryptocrediting are not the same thing

Coins that use the Proof-of-Stake (PoS) consensus algorithm – Tezos, Cosmos, BIP, and LOOM – initially support staking. While the value of stablecoins is tied to a specific asset – for example, to the US dollar.

Stablecoins are not available for styling, but loans – coins are issued as a loan to another user who pays a deposit in response. However, for investors there is no particular practical difference between staking and lending. That is why one can hear on the cryptocurrency market, for example, about “USDC staking”.

Real ROI and Volatility

Let us compare the return on investment in PoS coins and stablecoins and how this indicator is affected by the volatility inherent in the crypto market.

  • PoS coins . Each coin has its own nominal rate of return built into the algorithm. For example, for Cosmos (ATOM) it is 8.35%. However, a really important value is the real profitability, which is calculated on the basis of price changes for any period. For example, if you invested $ 10,000 in the stake of ATOM coins on January 1 of this year, then by June 1 you would have received a nominal income of about 3.5%. Instead of 2309 coins, you would have 2390. However, over the same period of five months, the price of a coin fell by more than 30%: from $ 4.33 to $ 2.96. The cost of the steak, along with interest, would be only $ 7075, and the real ROI would drop to -30%.
  • Stablecoins . Everything is simple with them: what rate is declared, the investor receives such ROI, minus the platform commissions. On cryptocrediting platforms, the rates are quite stable and allow you to predict income: for example, if you pay 1.94% per annum for USDC deposits on Fulcrum platform, then your profit in dollar terms will also be 1.94%, unless something out of the ordinary happens the USDC coin will not lose its peg to the US dollar.

Verdict: on average, the real ROI of stablecoins is higher and more predictable, as there is almost no volatility. A PoS coin can suddenly increase in price and bring profitability of 20% or more, but it can also lose half its value.

Number of platforms available and conditions

Next, we compare the number of available platforms for staking PoS coins and stablecoins and the conditions that they offer to holders.

PoS Coins

Dozens of platforms offer staking popular coins like Tezos and Cosmos. These sites can be divided into two categories:

  • Specialized sites are Staked, Staking Lab and Dokia Capital, among others.
  • Crypto exchanges – Bitfinex, Kraken, and KuCoin are among the smaller platforms.

Of course, platform competition is good for investors, but such a wide choice also means that you have to spend more time searching for information.

Having chosen a coin, it will be necessary to study the rates of return taking into account the commission at different sites, as well as assess the risks of each of them. Moreover, commission rates on different platforms can vary greatly, which affects the investor’s income. For example, for the ATOM coin, the Binance exchange promises a yield of 6–9% per annum, while on Stakin this figure will be 9.1%, and on – only 6.1%.


This type of digital asset can be deposited on various lending platforms:

  • Centralized – BlockFi, CoinLoan, Nexo, as well as a number of exchanges – Binance , Bitfinex, Poloniex.
  • Decentralized – Compound, Nuo, dYdX, Aave and others.

It should be borne in mind that different lending platforms can offer completely different rates for the same coin. For example, deposit income in USDC ranges from 1.25% to 8.6%.

Verdict: by the number of platforms, ordinary staking coins win. However, in the case of staking or lending in stablecoins, choosing a platform is easier: you do not have to compare so many options.

Risks: interest in the project

We have already mentioned volatility as a key risk factor. When staking stablecoins, the investor receives a reward in cryptocurrency , which can often be exchanged for fiat. But staking PoS-coins can lead to losses due to volatility. Another factor by which it is worth evaluating the profitability of investing in a PoS coin is the level of interest in a particular coin.

Stablecoins have a significant advantage: they were originally created as a reliable way to store and transfer funds between participants in a transaction. In the current crisis, investor interest in stablecoins can only grow. On the other hand, each PoS coin is a cryptocurrency of some kind of blockchain project , which can both succeed and fail. If the founders do not launch the product, then the price of the token may fall.

Another risk factor is the platform on which staking takes place. Both for stablecoins and for PoS-coins, both centralized (custodial) and decentralized (non-custodian) platforms are available. A cryptocurrency exchange like Binance is a classic example of a custodial solution: you transfer coins to the exchange for storage. If she is attacked by hackers, your steak may disappear.

In the case of non-custodian platforms, the risk of theft or fraud is quite low. It doesn’t matter which asset to use when staking or depositing and where: USDC – on Compound, USDN – on Waves․Exchange, XTZ – on P2PValidator.

And vice versa: on custodian platforms, the risks are higher, both in the case of providing stablecoins on credit, and in the case of PoS-coins staking. And since the bulk of PoS staking passes through exchanges such as Bitfinex and Binance, we can conclude that, on average, the risks of owners of PoS assets are more serious.

Verdict: PoS coins are more risky, because their price is highly dependent on both interest in the blockchain project itself and market sentiment. It is safer to choose non-custodian platforms for both types of coins.


Nominal rates of return for PoS coins are often very attractive, but price fluctuations can lead to negative profitability. In the case of stablecoins, a positive result is almost guaranteed. At the same time, you should not expect earnings on stablecoin more than 15-17%, although it is possible with a PoS asset.

Ultimately, the choice should depend on your personal attitude to risk. Investors who are willing to take risks in the hope of earning super-high returns should invest in a classic PoS coin – for example, Tezos .

If it is important for you to keep the investment (especially in the case of large amounts), then stablecoins are definitely preferable due to the better risk-to-ROI ratio.

As the global economic crisis deepens, more and more investors will acquire crypto assets. This will undoubtedly change the market balance in the segments of staking and cryptocredit. How exactly? We will find out soon.

TRON (TRX) cryptocurrency review – forecasts and prospects, current rate



5/5 (1 vote)

Cryptocurrency TRON (TRX) is a decentralized protocol based on blockchain technology designed to create a global entertainment network with free content.

In simple terms, TRON is a service similar to all well-known social networks and platforms where users have the opportunity to publish, view and use any available content for entertainment, for example, online games.

The TRON project is currently developing the idea of joint consumption, which is that on a single global platform, users will be able to share entertainment content.

Official TRON cryptocurrency website:

Analysts call this platform the broadcast of the modern entertainment industry. In general, the functioning of this system is as follows:

  1. The author or copyright holder publishes the result of his intellectual work on the official website. You can download anything from literary novels to an author’s song or art on a specific topic. Next, the participant uploads information about how his creation can be used (as an accompaniment to another work or as an independent product). Nearby, he indicates the price of his work.
  2. Another user who is interested in this work acquires it for the local currency Tron (TRX). However, users should remember that it is impossible to purchase this or that product on this resource using fiat money (dollar, euro, rubles, etc.). The system has its own cryptocurrency , which must be purchased at exchangers or exchanges in order to complete a transaction.
  3. As soon as the interested user has acquired the result of intellectual work, the amount indicated by him is transferred to the author’s account. The author can use the tokens at his discretion – purchase a work from another author, simply save money in his account, or exchange it for another cryptocurrency or fiat funds.

About what TRX is, initially interested in all users who are just starting their activities on the site. This resource uses several types of tokens for different purposes:

  • Tron (TRX) . This is the main currency of the system. For this currency you can buy or sell the results of your intellectual work. If necessary, the owner of a certain amount in this currency can exchange it for fiat money or other cryptocurrency.
  • Tron Power It is impossible to purchase or exchange other money for a given currency. The only way to get them is to secure the TRX currency on the site platform. In this case, they are converted to TR. The presence of such tokens gives advantages to their owner. For example, the holder of a TR has the right to vote for one or another change in the system, or to oppose them.
  • TRON 20 . Coins owned by developers. With the help of them, they create new full-fledged blockchains with new tokens.

The TRON cryptocurrency issue is limited, 100 billion coins have been issued at present. However, it is worth considering another point – starting in 2018, tokens begin to be burned (they are meant to be forwarded to an address known only to developers). The last major burn was in June last year, but how often such procedures will be carried out is currently unknown.

project team

The team of this project has on its side professionals working in various fields. The founder of the platform and the creator of TRX Coin is Justin Sun , who also created a social network with an audience of 10 million people. In 2017, Forbes magazine included Justin on his list as one of the most successful entrepreneurs, who was not yet 30 years old.

The technical director of the project is Lucien Chen , who has extensive experience in working for large Internet companies. He is perfectly versed in blockchains and the principles of functioning of cryptocurrencies.

Deus Yu , responsible for quality control, has been working in the computer games industry for a long time. According to Justin Sun, the experience of Deus will come in handy a little later, when the platform gains even greater popularity.

Charles Zhang , an adviser who is well versed in a business not related to cryptocurrencies and blockchains. He has repeatedly lectured on the basics of entrepreneurship, with which he was invited to many universities. Charles made a huge contribution to the promotion of the platform at the initial stage.

Blockchain Browser

Block Explorer is a search tool that allows you to view the addresses of wallets involved in the system, blocks, as well as data of transactions completed or committed. It can be compared with standard browsers, with the help of which an ordinary user searches for the information he needs on the Internet.

For each cryptocurrency, a personal Block Explorer is created that shows the network status for a given period of time. For the Tron cryptocurrency, such a Block Explorer is called TRONSCAN , where users can get all the information they need ( ).

How to mine Tron?

The developers of the platform did not provide for mining the Tron cryptocurrency , since they had already created all the necessary coins. In addition, the creators talked about the scheme according to which their cryptocurrency will work:

  1. 40% of the total number of coins will go on sale to enable the project to develop further.
  2. 15% of the remaining amount is allocated for acquisition by investors. Investors are players who, after the main sale of coins, will be ready to purchase tokens further.
  3. The remaining funds are “frozen” and remain in the accounts of the company owners.

Justin Sun explained that perhaps mining will be provided in the future when the company gains the necessary popularity.

TRX Token Wallets

The user can choose one of two options for storing Tron coins (TRX):

  • Storage of tokens on the exchange;
  • Creating your own crypto wallet.

With proper use, wallets provide a higher level of security. All types of wallets for Tron (TRX) are described in detail in this review .

Buying and selling TRX coins

You can buy a Tron on popular crypto exchanges , we recommend that you use the first 15 exchanges, and do not forget to install additional account protection. On the selected exchange, you must go through the registration procedure, after which you will be given a personal wallet, as well as its address.

The most popular and safe exchangers where you can buy and sell Tron:

The exchange rate of the Tron cryptocurrency against the ruble as of October 28, 2019 is 1.29 rubles per 1 coin. For a detailed analysis of the course and chart of coins, we recommend that you look at the Coinmarketcap website.

Development Perspectives and Company Roadmap

A distinctive feature of the project is its roadmap, which is scheduled until 2027. It is divided into several stages:

  1. Exodus It lasts from 2017 to 2018 and is considered officially completed. During this period, information about the project was actively disseminated, as well as developers were engaged in improving tools for using the site.
  2. Odyssey . Accounted for 2019-2020. During this time, developers will pay special attention to the economic development of the platform.
  3. Great Voyage . Captures July 2020 and ends in July 2021. Implementation of a personal ICO system, and third-party developers will have the opportunity to launch their own ICOs.
  4. Apollo It lasts from March 2021 to March 2023. Creating a decentralized exchange platform.
  5. Star Trek . It begins in April 2023 and ends in September 2025. Creation of a decentralized platform for the development of any computer games.
  6. Eternity . It starts in September 2025 and ends in September 2027. Platform users will have the opportunity to create their own playgrounds.

The developers mentioned that if these plans are implemented, a new roadmap will be created in the future, which will begin in 2028.

When analyzing the active nodes of the Tron cryptocurrency, you can notice the scale of the development of the project, where the majority of servers are located in the USA, China and Germany.

The forecast for Tron cryptocurrency from leading analysts suggests that, taking into account the current features of the crypto asset, in the future the project can absorb the entertainment market. And this means that in 2020 the value of one coin is able to stand on one level with the dollar.

Main competitors Tron

The project has two main competitors – Qtum and Ethereum . Each competing company has its own advantages, for example, the first has a more advanced platform in terms of technology, and the second wins due to smart contracts and fame.

Analysts are confident that the Tron platform will still have to fight for its users, since the developers are aimed at a specific audience. However, the Throne does not have special advantages that would distinguish the project from its competitors, which could become a serious problem in the future.


Tronix cryptocurrency has good prospects for further development, since the project itself is one of the most ambitious among others. However, at present it is not in demand. Investing in such a project will bring quite large risks, however, long-term investments can bring the investor good profit.
