Uservice is a Global Decentralized Blockchain Platform for the Auto Industry 325

Global blockchain ecosystem Uservice token pre-sale had launched. The aim of the project is to unite and optimize all processes related to the purchasing, operation and maintenance of the car. Today there is a huge number of car platforms. Each of them has certain functions – some sell cars, others check if the car was ever in an accident, others offer assistance in repairs, etc. This separation is not convenient for the car owner. We took this into account and created a unique interactive blockchain ecosystem called Uservice. This separation is not convenient for the car owner. We took this into account and create a unique interactive block system for the Uservice ecosystem. Combining a large number of dealers, car service providers, insurance companies, suppliers of spare parts, and many other platforms of the auto industry, we will achieve the most effective interaction of individual links, combining them into one single chain.

Uservice project is a decentralized online platform based on the Ethereum blockchain, in which the smart-contract system will be used. Ethereum technology makes it possible to register any transactions and operations with cars based on a distributed base of contracts such as blockchain, without using traditional legal procedures. All operations with the car will be transparent, controlled and safe.

Connecting to Uservice platform of car owners, car service centers, insurance companies, banks, state regulators and car manufacturers, we will become a collective market of the “full life cycle of the car”.

By introducing an internal UST token into our ecosystem, we create a mechanism of interaction for the ecosystem participants within a single platform. UST tokens are released in a limited quantity and will be a part of all interactions within the project. We expect that the number of participants of our platform will increase, which means that the cost of the UST token will grow.

uefa launches a blockchain app

The UEFA wants the fans to have the smoothest experience ever. Right now, buying tickets for football matches is one of the most problematic areas: tickets are often falsified and stolen, moreover they are very hard to get. That’s why the organization is researching new technologies to fix the problem.

UEFA has recently announced about the testing of blockchain for developing a ticketing app. The app works via bluetooth on electronic devices and will be used when entering the stadiums.

The report said: “Fine-tuning and improvements took place at several test events, and the system was first used for 50% of the tickets distributed to the general public for the 2018 UEFA Europa League final between Atlético and Marseille in Lyon.

The Association will keep on developing its blockchain-based app, and, hopefully, football fans will soon have an opportunity to use it.

Forbes Published 5 Main Blockchain Tendencies for 2018 782

blockchain trends

Blockchain is one of the most rapidly developing technologies of all times. Its main features (speed and transparency) earned recognition and approval from businesses and companies from all over the world.

Forbes has conducted a research and established 5 major paths that the blockchain is likely to follow this year.

1. Companies actively implement blockchain. For example, we have recently reported about the pilot version of election in Ukraine conducted on blockchain.

2. Implementation of this technology follows a thorough research. With blockchain being fairly new, the more conventional fields that are not related to digital technologies or computer sciences treat it very carefully. For example, the Stanford University created a research center for possible introduction of blockchain in the future.

3. The hype is going to fade. Blockchain has been marketed as a panacea for quite a while. Many people were sure it would help to solve major world problems. However, the results coming from this technology, though being mostly beneficial, are not as phenomenal as everyone thought they would be.

4. New and smaller projects are more likely to implement blockchain since they are more adaptable to changes and upgrades. Huge companies like Amazon find it way more difficult.

5. The personal information on people and other important data will be secured a lot better with the help of blockchain. Scammers never rest, however, blockchain will ensure that they have the hardest time ever hacking and stealing.

Thus, we can definitely see a lot of potential for blockchain. More and more companies choose to implement it. Hopefully, this technology will keep flourishing and bring benefits to those using it.

How to Cancel A Bitcoin Transaction? What to Do if a Transaction Froze? 975

how to cancel a btc transaction

The user database of the Bitcoin network is growing every year. The novelty of the industry implies the presence on the market of a large number of non-professional investors. They, because of lack of experience or by trivial inattention, can voluntarily lose their digital assets, simply by sending them to the wrong wallet. In this article we’ll talk about why you cannot just cancel a BTC transaction and what to do if it froze.

Contents:
(please, click the topic to scroll down to it)

  1. Is it possible to cancel a BTC transaction?
  2. Why is it impossible to return Bitcoins?
  3. The transaction isn’t responding, what should I do?
  4. Conclusion

1. Is it possible to cancel a BTC transaction?

As already mentioned above, unfortunately, it is not possible to cancel the transaction in the Bitcoin network technically and physically. In the history of the coin, many users, on their own bitter experience, were convinced of this feature of digital currencies. At first glance, this may seem to be a developer’s fault, but if you recall the blockchain technology, which underlies cryptocurrencies, then everything falls into place. The fact is that Bitcoin is a decentralized system, that is, it does not have a single center from which it would be possible to correct the direction of transactions. It is worth noting that cryptocurrencies gained their popularity precisely for the opportunity to exchange coins without the control of intermediaries.

You can see the transaction queue, but you cannot return the funds. Transactions in digital currencies are different from traditional electronic systems. The process of conducting transactions consists in rewriting the balances of two wallets (the sender’s and the receiver’s). Data about this operation is written to the registry, after which it is no longer possible to change it.

2. Why is it impossible to return Bitcoins?

Due to the peculiarities of the technology, it is not possible to reverse the transaction. If You, for example, bought something on the Internet and paid bitcoin, but want to make a return of the goods, then You need to contact the seller to make a new transaction to Your wallet. Since the data on Your payment has already been successfully entered in the register and nothing can be done about it.

But what to do if You accidentally sent money to the wrong wallet? Let’s be honest, unfortunately, you have to put up with it, since most likely you will not get it back. Although the Bitcoin address, to which the transaction was made, is in the public register, there is no possibility to find a person by name or surname. Therefore, You cannot 100% know of whom you have sent your digital assets.

3. The transaction isn’t responding, what should I do?

A long time of confirmation of transactions in the Bitcoin network is the weak point of this payment system. The BTC algorithm is designed in such a way that it can handle only 7 operations per second, so sometimes users have to wait for the transaction to complete for several hours or even days. But it happens that they hang for a very long time, for what reasons can this happen?

  • a sudden break in the Internet signal;
  • setting a too small commission fee.

What should you do in this case?

  1. First, you need to make sure whether the operation is actually suspended or whether the queue has just not yet arrived. Open Block Explorer, it will be indicated there.
  2. Next, go to the debugging console (Help-Window-Debug-Console);
  3. Get a private key from your wallet.
  4. Export private access keys to all bitcoin addresses, on which there are funds.
  5. After that, close the application and delete the wallet.
  6. Again run the client of the wallet program, create a new wallet and import private keys. Prepare that this process will take a sufficient amount of time.
  7. Done. In the new wallet, access to blocked funds will be resumed. In this way, you can undo an unconfirmed Bitcoin transaction.

It is important to understand that this instruction does not apply to cloud wallets.

4. Conclusion

Performing transactions on the Bitcoin network one should be extremely careful, since they cannot be reversed. This is both the main feature and the lack of the system.
