On 22nd March, a cyber-attack was discovered in the US city of Atlanta. In the attack, hackers shut down the main computer systems and demanded $51,000 in Bitcoin for re-enabling the affected systems. It was noted that this disruption was affecting systems through which some consumers used to pay bills and access information related to court. Computer hacking isn’t something new to hackers as cryptocurrency related hack has been attempted by them many times before.

According to some reports, the officials of the city are working with the US Department of Homeland Security FBI, and Microsoft to discover the extent of this violation and to find ways to resolve it. City officials invigorated citizens on 23rd March, in order to check their personal accounts and information, if any of them think that their personal information could be conceded in the hack.

Public Announcement of The Attack

The attack was announced by the mayor of Atlanta, Keisha Lance Bottoms, in a press conference on 22nd March. The members of the press were told by her that the officials still don’t have any idea about the extent of the attack or if bank accounts or personal data of anyone will be compromised as she stated:

“All of us are subject to this attack.”

Is there anything done to resolve the situation?

However, the situation still needs to be resolved. The price of Bitcoin is trading at $8,469 at this very moment, which shows that the demanded ransom is going to cost the city around 6 bitcoins as this is not the very first attempt of hackers to hold municipal computer systems as a hostage in exchange for the cryptocurrencies.

Former Attacks Linked to Bitcoin

Back in November 2017, Sacramento Regional Transit system was attacked by a hacker for a ransom of 1 bitcoin demand, and bitcoin had the worth of $8,000 at that time. Another malicious example of ransom for Bitcoin is from December 2017, when a parcel bomber in Germany demanded a €10 million ransom to be paid in the form of Bitcoin as he sent this in a message to a Potsdam Christmas market. However, the package failed to explode and had a QR-code for depositing bitcoins, as well as explosive material that was derived from nails and fireworks.

Want create site? Find Free WordPress Themes and plugins.

Reasons to Use Bitcoin

Bitcoin is cryptocurrency that came into circulation just a few years ago. Some critics call Bitcoin unsafe to trade form of currency due to the facts that it has no authentic value, can be used to make illegal transactions and there is no regulatory authority to keep it under control.

Despite above-mentioned concerns, the interest in bitcoin from different corporations keeps growing each day. Let’s take a look at some of the good reason as to why using Bitcoin value is a good idea.

GOOD REASONS TO USE BITCOIN:

How to use Bitcoin?

Payments Are Quick:

The transactions made through banks or wire transfer are often slow and take several days to complete. On the other hand, Bitcoin transactions are instantaneous and take seconds to a few minutes to complete.

Usually, Bitcoin transactions are categorized into two types: zero confirmation and the transaction in which the merchant needs approval.

Zero confirmation transactions complete within a few seconds. However, the transaction with merchant’s approval may take up to 10-15 minutes to complete; which is still pretty quick compared to traditional transactions.

Inexpensive:

When it comes to making quick transactions, one might say “credit/debit card transactions are also quick, so why use Bitcoin?”

The answer is that to buy bitcoins with credit/debit card charge a certain fee for using this service. On the other hand, Bitcoin transactions are quick and charges involved are extremely low.

No Chargeback Frauds:

With bitcoins, the sender cannot reclaim the coins without the consent of recipient which ultimately eliminates the chargeback fraud – a fraud which is pretty common for credit/debit card users.

What happens in this fraud is that people purchase an item and if it turns out to be defective, they get in touch with credit card agency and ask for a chargeback, which effectively reverses the transaction.

Personal Details Safety:

Credit card numbers are always at the risk of getting stolen during an online transaction. On the other hand, Bitcoin transitions are theft-proof. All that is needed to complete a transaction is to match Bitcoin key with your private key and you are good to go.

Bitcoin Is Not Inflationary:

Whenever the economy is sputtering, the government prints new currency and injects it into the economy to strengthen it. The approach results in inflation. However, such is not the case with Bitcoin. The currency is finite and designed to reach no more than 21 million coins before the year 2140.

This means the more people use this currency, the more it appreciates in value.

These are some major reasons as to why you should use bitcoins value 2017 instead of credit/debit card to trade. Some more reasons to justify the bitcoin usage are:

  • All transactions are stored in a ledger called “Blockchain”. The ledger can be accessed by anyone, keeping the transactions transparent.
  • Micropayment like 22 cents are free
  • Numerous major corporations like Reddit, Pizza Chains, Bank of England and Fed, WordPress, etc. are now accepting bitcoin payments.

In conclusion, bitcoin is extremely secure compared to traditional currency. The use of Bitcoin is increasing each day and it’s pretty safe to say that future belongs to Bitcoin – the most popular digital currency out there.

A Violent Shock For JPMorgan Chase As the Lead Quits

Want create site? Find Free WordPress Themes and plugins.

JPMorgan Chase & Co is a well known financial services company which operates around the globe. Along with blockchain projects its financial operations include:

  • Corporate & Investment Bank,
  • Consumer & Community Banking,
  • Asset & Wealth Management,
  • Commercial Banking.

blockchain startups

Founded in 1799, JPMorgan Chase & Co. has its headquartered in New York and is thought to be one of the most dependable financial services company. All was going on very well for the company until Amber Baldet, an executive leader of JPMorgan’s blockchain, decided to quit the company in order to head for her own new Blockchain initiative.

Who In Fact Is Amber Baldet?

Amber Baldet was one of the main executive leaders of JPMorgan’s blockchain business. She was head of the development of JPMorgan’s authorized Blockchain platform. She had been acting as the lead for project development of Quorum as well as working on the firm’s overall Blockchain technologies strategy. In true words she was the architect of JPMorgan’s blockchain startups, securing a critical position at JPMorgan’s Blockchain Center of Excellence. She has done so in order to launch her own blockchain firm. Quorum is JPMorgan’s Blockchain and smart contracts platform.

 

Amber Baldet was nominated as one of the most influential people in the history of Blockchain by BlockDesk in 2017. She was heading the JPMorgan’s Blockchain Center of Excellence since it was founded in 2015. She was considered to be the most precious assets of JP Morgan in terms of blockchain endeavours.

Who Will Take Over Amber Baldet’s Position?

It took a very short time for JPMorgan’s executive committee to name Baldet’s successor. Christine Moy has been appointed as the new executive leader in place of Amber Baldet. She was the senior product manager working under the supervision of Amber Baldet and by chance was also appointed by her. In fact she had been working with Amber Baldet since the very beginning of the blockchain project. Later on the company admitted in a statement that Amber Baldet was no doubt extremely committed and helpful for JPMorgan to build an outstanding team. Christine Moy  was one of the team members who was groomed and trained by Amber Baldet herself.

 

Baldet’s departure from the company was after all on good terms, as was exclaimed by JPMorgan spokesperson in an interview with Reuters, he stated that the company had a respect and best wishes for her as well as her desire to start her new venture.

 

As far as the case of smart contract platform Quorum is concerned JPMorgan considers it to be the “enterprise-focused version of Ethereum.” It is basically meant for the clearing of interbank payments with the help of blockchain.
