hello,
are there any news about this project?
would be interesting to know how far you got into the mission of achieving a stable crypto coin...
what are the developments on the last 2-3 months?
thanks

Hello! Thank you for your interest. The general cryptomarket falling has tightened the process of stabilization of XPO at the GAV level. But the crypto-currency wallet, the XRSS stabilization system and the bots are debugged and work.
Recently, we have focused on developing GLOBULA game - the next step of our project. The release of it will ensure a constant demand for coins at the GAW target price. The expected period of stabilization is the beginning of 2019.
As for GLOBULA, at present, MVP is ready, we continue the development.

thank you for your quick reply
These are good news Smiley
I just think you should invest a bit in marketing otherwise there is the risk of not getting enough participants in the game...
this is a good idea and an on-going project, just seem to need more attention...  Grin
cheers
Yes, you are absolutely right. And  we are looking for a strategic partner right now for a broad marketing campaign.

Re: Any good ICO there?

There is some altcoins that doesent require any mining. Please, check out our project:XRONOS. We finished tests of our algorithms (for a year our system worked with dublicates of real market data, but without huge amounts of money), and already have done presale about a week ago. The main idea is a backing of our coins with other coins in different proportions, depending on their share on the market and their prices fluctuations. So it's a sort of an investment stabilization and insurance which will help avoid some separate coins' collapses, and as a whole it follows the general trend of the market (meaning a growth in a long-term, and smaller possible losses in a short-term). Collected data is open and available at stats.xronos.space.

Presale results: step 1 is finished, 3 more to go.
One month ago we started a presale. There was an announcements, pros and cons, risks, perspectives — all info was open for any user, that interested in this theme. Some people liked our project, other were critical. Now month passed, it's time to sum up.

October 21st presale was finished. Total emission equals 36435,632 XPO at a price of $ 2.15 each. At the end of presale we acquired 17.61 BTC. There is 106 unique backers, that believed in XRONOS. We want to thank the participants for supporting the idea.

The XRSS has confirmed its efficiency: at the end of the presale the backing of each XPO coin increased from $ 1.79 (80% of selling price) to $ 2.46. This is entirely the merit of the XRSS, which allows XRONOS gradually increase the price of coins through supporting orders

During the presale we received a lot of feedback: both positive and negative. We will listen the reasonable voices of the crypto community (which not only hung labels, but also argued their point of view), and we will correct the development strategy and product positioning. We want to make uniquely XRONOS perception by users, and that support of community was invaluable. Thanks to everyone who supported us with criticism or bitcoin: with you we will become stronger and now we can achieve our goal faster than before.

Project news
There are two releases of the Xronos Wallet application is planned this week: the version for iOS and the updated web client with the introduced two-factor authorization.

The work on the XRONOS software core was continued; within a month before the ICO we will continuously test and release updates of system soft. In particular, we want to expand the functionality of the personal cabinet for better user experience.

New exchanges and our plans for ICO
During November, everyone will be able to use the XPO / BTC cryptocurrency pair on a decentralized exchange. At the presale there was only one exchange avilable for trades, but now we are negotiating with new exchanges about the establishment of partnership. At the time of the Xronos release in exchange trades, speculative growth of its price is expected to be approximately 20-30%. It will be achieved through a constant wall of buy orders, thanks to which the liquidity of the coin itself is ensured.

The next step of the coin sale (ICO) will take place on the planned dates: from November 21th to December 21th, 2017.

Thank you for your trust.
Sincerely, The Xronos Team.

Итоги presale

Месяц назад мы объявляли о начале Presale: рассказывали об условиях, о достоинствах и рисках финансовой модели, о возможностях для новых пользователей. Некоторым проект понравился, другие его критиковали — но вот прошёл месяц и настало время подводить итоги.

21 октября завершилась первая тестовая распродажа криптовалюты XRONOS. Всего было продано 36 445,105 XPO по цене $2,15 за единицу. На момент завершения presale было собрано 17,61 BTC. В проект поверило 106 уникальных пользователей.

Благодаря работе XRSS удалось довести обеспечение каждой монеты XPO с $1.79 (80% от закупочной цены) до $2,46. То есть алгоритм работает не только на тестовых данных, но и на вполне реальных деньгах, и мы рассчитываем на аналогичную динамику в ноябре. Именно XRSS позволяет постепенно увеличивать цену монет через стену поддерживающих ордеров.

В процессе распродажи мы получили множество отзывов: как позитивных, так и негативных. К разумным голосам криптосообщества (которые не только навешивали ярлыки, но и аргументировали свою точку зрения) мы прислушаемся, поправим стратегию развития и позиционирование продукта так, чтобы устранить неоднозначность восприятия XRONOS пользователями. Спасибо всем, кто поддержал нас критикой или биткоином: с вами мы станем сильнее и быстрее добьёмся своей цели.

Новости проекта

На этой неделе запланирован выход нового приложения мобильного кошелька: мы наконец завершили разработку и прошли модерацию в магазин для iOS. Веб-версия XRONOS WALLET получит прошедшую тестирование двухфакторную авторизацию.
 
Не останавливалась работа и над программным ядром XRONOS, в течение месяца перед ICO мы планомерно будем тестировать и выпускать обновления в релиз. В частности, пользователей ждёт расширение функциональности личного кабинета.

Новые биржи и рост курса на ICO

Мы продолжаем развивать проект в сторону децентрализации и договорились с новыми биржевыми площадками о партнёрских отношениях и торговле парой BTC/XPO в преддверии второго этапа распродажи монет, который пройдет с 21 ноября до 21 декабря 2017 года.
С выходом XPO на открытые торги на биржах ожидается спекулятивный рост цены монет приблизительно на 20-30%.

Re: [ANN][XPO] XRONOS: an aggregator of cryptocurrency and blockchain-technologies

The time has come! XRONOS, the first aggregator of cryptocurrency, is 100% ready to work. XRSS is on alert. The website is launched. Technical documents are designed and imposed. We can begin. Presale of XPO coins will last till 21 October, 2017.

Elevator pitch
To someone who missed our previous posts, XRONOS is the first aggregator of cryptocurrency and blockchain-technologies. The main goal of the project is to create so-called Stable Coin: cryptocurrency which is stable in relation to fiat money. Consider it something like “Bretton Woods” system in digital performance, but instead of tangible and finite gold, other cryptocurrencies and their increasing capitalization are used as its backing.

What’s inside?
The system consists of three products (own blockchain, Wallet app and XRSS program). Together they form XRONOS cryptocurrency, stable to fiat money. Each of the products has its own unique features. All of these features make the project a breakthrough.
Blockchain XRONOS operates on the highest speed, it is self-optimizing and linearly scalable.
XRSS - XRONOS Real-time Stabilization System - works by transparent rules, its operation is based on fully open sources, which allows everyone to predict ts behavior and to stay confident in the system’s reliability. You can learn more about it, following this link.
XRONOS Wallet differs from classical crypto-wallets, because of its lightness and the fact that the user does not need much space on his device, and open API allows to expand its functionality in a snap.
All of the three products are fully completed and ready to be tested by the first users, who will take part in the Presale of the new cryptocurrency from 21 September to 21 October, 2017.  

Planned results and global goals?
As we’ve already said, the closest and tangible goal is to create Stable Coin, which is cryptocurrency not attached to any fiat currency, but stable to them.

Globally, we want to create such a crypto circulating medium, which will enable cryptocurrency to enter the real sector of economy, to push outdated banking system and to ‘let the genie out of the bottle’ - to start a process of forming p2p-economy. To make it happen, our crypto must be truly decentralized, stable and, what is more important, mass-applied. This is what we aim for.

4 Stages of exchange rate stabilization
For active growth of user database at the beginning and its further development, XRONOS has a planned period of speculative growth, divided into 4 parts. Each one of the stages is connected with the sale of extra XPO coins and guaranteed rise in price of the coins at the next stage. This way the functionality of the system can be gradually updated, tested and expanded without any security risks, while the capitalization of the new cryptocurrency will be increasing by degrees.

The uniqueness of the project Presales and ICOs is in allocation of the funds: just 20% of the gathered funds at each stage will be spent on development of the cryptocurrency and its services, while the remaining 80% will guarantee the financial capacity of the coin. This will back its liquidity, refund guarantee and lower the risks for the first users of the system.

Period of exchange rate growth is divided into 4 so-called “Stabilization stages”:
Presale XPO, $2.15 per coin will last from 21 september to 21 october 2017;
ICO XPO, $3.50 per coin will last from 21 november to 21 december 2017;
Presale Globula, $10.75 per coin will held in march of 2018;
ICO Globula, $16.15 per coin will held in june of 2018.

What’s next?
After the emission of 21 million coins, XPO transforms into stable rate. Its arithmetically predicted cost equals $21.53 for 1 XPO, but in August 2018 it may be slightly corrected, as XRONOS is based on GAW and SDR indexes. Once the target values are reached (emission> 21,000,000 coins and a stable XPO rate), the percentages of the emission earnings distribution will change: 98% will go to the cryptocurrency basket, and only 2% will be spent in the Vertex Capital Management LTD favour, so the work on XRONOS and its motivating services can be continued.

How to take part?
The starting point of the work with XRONOS is Bitcoin-wallet with some funds charged to it. Via your wallet you will be able to buy XPO coins. To work with the system you will need a personal account, which you can create here or using your mobile app. And your further actions are simple: enter official website and buy yourself a piece of your bright future. Smiley

Next week we will start doing detailed reviews of each element of the system, and by the Presale mid-point you will understand the way the project is organized just as good as we are. Have a good weekend!

How will XRSS work and how will it back the rate stability?

XRSS — XRONOS real-time stabilization system — is a complicated technology, lying in the base of XRONOS aggregator, making it unique. XRSS is the one responsible for XPO exchange rate control and transferring the funds into / out of the system. Operation options are not pulled out of the hat, but, of course, logically constructed.

Let’s mentally teleport to the nearest future, when Presale and ICO are over, and XRONOS becomes a Stable Coin. How the system works in field conditions? Where the exchange rate comes from? How it is controlled by the system? First things first.

The price of 1 XPO is attached to GAW value and it is denominated in SDR. What these abbreviations stand for? GAW is a worldwide average index, expressing the cost of a working hour on the planet. Its calculation is based on the open data, officially provided by OECD member countries. These countries take the data from revenue services and other institutions doing statistics.

SDR is the index used by IMF for internal calculations between member states of the fund. It consists of five largest and strongest currencies in proportion to their volume in the global economy. It is like a powerful cryptocurrency basket, which is so heavy, that it stays stable, especially comparing it to the prices storm at the currency exchanges.

That means that the price of 1 XPO is bound to two average indexes of global economy, which are stable and secure enough to rely on. Backing and liquidity are the only things that left to sort out.

How to hold the exchange rate in leash?
Firstly, the correct price of the coin must be calculated. All the computations on the planned XPO price are conducted by so called XBA, analytical xronobot. It is also responsible for other tools’ operations, which are two other xronobots (XBE and XBG), and for strategy of “digital gold and currency reserve”, meaning cryptocurrency basket. To make it happen, the bot gathers the statistics on cryptocurrency and market conditions, information about GAW and SDR, analyzes the data and acts basing on the results. It constructs a plan for rates of purchase and emission of XPO during next 24 hours.

XBE - emitting xronobot
Since XRONOS doesn’t use mining as new tokens resource, new coins emission is conducted only through its purchase at the market. Income is directed to the guarantee xronobot.
The intensity of emission depends directly on its demand. Tons of crypto needed ASAP? Then xronobot emits coins at the price of GAW +1%. Supply at the market is much higher than demand? Then emission won’t be conducted at all, users buy out all of the other users’ coins, who needed conversion into crypt or fiat money.

XBG - guaranteeing xronobot
XBG is a distributor of “digital central bank”, which manages the gathers cryptoassets. Approximately 40% stay in the cold storage, others are used at the exchanges as the cryptocurrency basket. It also conducts demission of the funds, or in simple terms, its conversion into fiat money. If the XPO supply is higher than the demand, the coins are bought out by the bot at the price of GAW-1%. It takes money for withdrawal from selling the gathers goods.

Cryptocurrency basket
In fact, this is a diversified storage for cryptoassets. Based on the data of the bot-analyst, XBG purchases a package of "crypts" in accordance to the market situation: preference is given to the most actively traded and stable coins. Their total capitalization equals 90-98% of the cryptocurrency market.
The information about current state of the cryptocurrency basket managed by xronobots is open and available on the official website. It’s updated once a day.

Common logic
In sum, XRSS works with a pretty trivial logic. Someone needs new coins - he just buys them on the exchange from other users or from chronobot. The rate is calculated by the bot-analyst and is controlled by two systems: emission and demission. The first sells coins at a price higher than the planned one, the second one is buying them at a price below the target. So users can only have a narrow 2% corridor of exchange rate fluctuations. If the price is out of it, it is more profitable to use xronobots.

Withdrawal guarantee
The funds withdrawal is fully guaranteed by the accumulated crypto-assets. The fact is that XPO is bought in the crypto, and the price equals the rate of fiat money for a certain day. In the long term, the "crypt" will only rise in price, so 0.01 BTC invested once will increase its dollar / euro value. As a result, for the return of funds from the system it will be necessary to spend less "bitcoins" or other crypto currencies, so that all XPO can be safely bought and sold: this will practically affect neither the exchange rate of the cryptocurrency nor the stability of the market.

Balance of forces
In the end, we have a simple and harmonious picture. Analytical bot calculates the standard price of one XPO coin and the composition of the cryptocurrency basket. Emitting bot sells new coins at the price that is 1% higher than the standard, and it also transfers income into cryptocurrency basket. Guarantee bot buys up unnecessary coins for 1% cheaper than the standard, meaning, it provides a guaranteed fast and safe withdrawal of funds. Speculators have no chance.

Today
It is the right time to come back from elegant theories to harsh reality. Crypto-market is very speculative, and it is really hard to bring attention to the currency, which won’t rise in price. That is the exact reason why we conduct 4 steps of stabilization (2 Presales and 2 ICOs), during which the rate will be gradually rising up from 1/10 of the price to the planned number.

It is an instrument for gaining popularity for us. For you it is, firstly, a test-drive of the system with transparent risks and, secondly, an opportunity to gain some funds on your trust towards the project.

XRONOS

Current situation of the market of crypto-investments

Most people want to invest not in hundreds of different cryptocurrencies and ICOs, but in a more complex technology - Blockchain. The question is simple, do people believe in this technology or not? For those who believe - XRONOS provides a perfect option for expedient investment. XRONOS is backed by ~ 95% dynamic portfolio of foremost crypto assets, which means that XRONOS ensuring reflects the movement of the entire crypto-market. From this point of view, XRONOS is a set of capitalizations of all the coins that make up the backing portfolio. But this is how it just begins…

About XRONOS in a nutshell

XRONOS — is an absolutely new stable cryptocurrency backed by dynamic portfolio of crypto-assets and supported by markets of application. The cost of one coin is attached to the average man-hour expressed in SDR.

Specification

Hashing / encryption algorithms: AES, DES, RSA, Blowfish, SHA-160, SHA-256, SHA-512
Block Time: Immediately
Consensus: Own algorithm. The development uses the principles and technologies underlying the well-known algorithms and protocols: CryptoNight, Zero-knowledge proof and Proof-of-Stake.
Protocol: Custom format. The protocol is based on a "ring signature" (similar to the CryptoNote protocol).
Fork: Xronos is not a fork, it's 100% new code
Multi-Signature: Yes
Opensource: It is planned to be opened after a number of external audits, and after reaching the last stage of stabilization
Official ticker: XPO
The target price of XPO: GAW (currently $21.53 or 15.215 SDR)
Starting XPO price: 1/10 GAW


Primary goal

The goal of XRONOS is to create the first truly stable cryptocurrency.

Secondary goal

Creation of a user environment which allows the most efficient allocation of economic and other useful resources through the use of Smart Human Relations contracts, the fulfillment of which is guaranteed via geolocation arbitrage.

Mission

Short:
Our mission is to create a truly decentralized, stable, massively applied crypto payment instrument that will accelerate the process of fiat money transformation into cryptocurrency and help move from an outdated banking system to a new stage of the world economy evolution.
Mission in details

Emission mechanism

Minting - emission is based on the sale of XPO by an emission robot on a decentralized exchanges at a fixed price.

Nodes owners rewarding

Masternodes are required to have 1000 XPO collateral, a dedicated IP address, and be able to run 24 hours a day. Masternodes get paid from network TX-fees, in which it participates.
The appearance of new nodes occurs dynamically when the network reaches a certain number of transactions for a certain period. TX-fee for each transaction is constant and equals 0.001 XPO.

Key advantages

- Unique stack of reliable technologies. 100% new code
- Off-Chain transactions - disconnection of the recipient-sender chain due to the bonds functioning
- Unique combination of PoW and PoS technologies, so as CryptoNight and Zero-knowledge proof algorithms
- Instant transactions - at the moment 96 TPS with a load of 2000 threads, but this is clearly not the limit.
- Network elasticity, expandability and scalability
- XRSS - system of rate stabilization based on adaptation of collective decisions by ring signature and ZKP
- Self-optimizing blockchain
- The technology enabling reformation of labor markets and world legal system
- Simplicity of use and integration
- The mechanism of virtual (or game) objects tokenization.
- GLOBULA – innovative tool for demand stimulation


What is GLOBULA - extremely short description

GLOBULA is a geolocation game of a new genre, we call it MGMOGRCE (Massively Geolocation Multiplayer Online Game with Real Crypto Economy).

XRONOS is the only currency applied in the GLOBULA world. The game itself creates a monopoly market for the circulation of cryptocurrency: a large number of different items and resources. In addition, the game has a geolocation quests constructor, which allows you to create a variety of user-generated content.

This constructor is actually the progenitor and the test lab of a more complex system of interhuman interactions based on the eventive language SHRL, which is the basis of the future Work.space product.

We believe that the most effective way of integration of certain innovative technologies is to implement them into a global game. Therefore, Globula is not just a side product of Xronos, but it is one of the key tools for full-fledged application of Xronos into everyday life.

You can read more details in our Whitebook. The information solely about the game is available at www.globula.space.

ICO and Presale

Presale XRONOS: 1 000 000 XPO have been offered at the rate $2.15/XPO. Presale took place from September 21 to October 21, 2017.
ICO XRONOS: 9 000 000 XPO - The price for XPO is to be established in accordance with the formula BUY ORDERS WALL*20%, but not lower than $3.50 for XPO.
ICO will take place from November 21 to December 21, 2017

Further minting will be available at the rate of GAW + 1% (at the moment it is $21.74)
