blockchain startups

Thanks to Bitcoin and all the related cryptocurrencies, blockchain startups no more a mystery. All those who are somehow related to the crypto market know that the blockchain technology is infact a decentralized technology that keeps the record of digital transaction and has so far its use been specific for the crypto transactions. To be more precise and accurate we can state that a global network of computers uses blockchain technology to jointly manage the database that records Bitcoin transactions. Blockchain is considered to be invincible because it can continuously replicate itself on multiple computers and databases.

So far Blockchain had been used in case of cryptocurrency transactions only but with the passage of time its use expanded for example in determining identity of digital assets, smart contracts, digital voting and distributed storage etc. Porsche can be considered a pioneer who for the first time decided to utilize Blockchain technology in car manufacturing. Let us see how they did it.

First Use of Blockchain in Automobile industry

With the help of  Berlin-based XAIN, Porsche has become the very first automobile manufacturer to successfully test blockchain in its cars. Blockchain technology based digital processes are both secure and super fast than anything that has come before. Test which was carried by the manufacturer of Porsche included locking and unlocking of the vehicle via an app, access authorisations and encrypted data logging. It is a part of further planning to improve autonomous driving functions of Porsche with the help of Blockchain technology.

What is the Plan of Audi?

For the time being Audi is planning to use Blockchain technology for its physical and financial distribution processing. In short Audi is just making an innovative effort to make its global supply chain more transparent and foolproof. For this purpose the car manufacturer also released a Proof-of-Concept (PoC) of its Blockchain system last year. As a result of positive feedback the manufacturer has now decided to advance the project beyond the PoC stage.

Moreover, the management of Audi is further researching on Blockchain in order to improve the process of data transfer and make it more safe and effective.

Interest Shown by other Car Manufacturers

Like Porsche other German car manufacturers such as BMW and Mercedes have also hit the news with announcements of their interest and expected experiments with Blockchain technology. According to authentic reports, BMW is planning to expand its portfolio by partnering with a Blockchain startup. Mercedes Benz has even took a step forward and has announced that it may issue its own cryptocurrency by the name of MobiCoin. According to the initial announcements Mobican will be used to reward drivers for their environmentally cautious driving.

Guide About Bitcoin Wallet

A Bitcoin wallet address is equivalent to a bank account for tangible cash. In bank accounts the money is deposited, withdrawn and transferred to other users. Same is the case with bitcoin wallets. These wallets are used to store/withdraw bitcoins and transfer them to other users. There are three major types of bitcoin wallets: web wallets, software wallets, and mobile wallets.

Web Wallets:

Also known as “eWallets” or “browser-based wallets”; web wallets are the easiest to protect and give you complete freedom to use/obtain bitcoins.

Some of the examples of web wallets are:

  • BitGo

Software wallets are installed on your PC. The users have complete control over Software Wallets and are responsible for bitcoins’ protection and backups.

Mobile Wallets:

The users with Mobile Wallets have the freedom to store bitcoins on mobile devices. Mobile Wallets are simple and easy to use while transferring coins. All a user has to do is to scan the QR code using “tap to pay”.

How Do Wallets Work?

Each Bitcoin wallet comes with a private key. The key allows a user to spend the coins. It’s usually the owner only who knows about the key. However, if you are not careful enough with protecting the key, there is a huge chance that someone else will be able to figure it out and spend your coins.

Multifactor Authentication:

Multifactor Authentication is an additional security authentication to your password. This could be something like a favorite quote, secret question or a captcha.

Private Key Encryption:

Encrypt your private keys. A private key in plain text is easy to guess and easy to access. So, make sure your key is encrypted.
