Bank of America Fears for Its Business Model Due to Cryptocurrency 995

The annual report filed by the Bank of America with the SEC (Securities and Exchange Commission) contains a number of economic, geopolitical and operational risks that the bank sees for its activities in the new financial year. For the first time for all the activities of the bank, there were cryptocurrencies in the report.

“Widespread adoption of new technologies in financial services, including cryptocurrencies, could require substantial expenditures in order to adapt to evolving industry standards and consumer preferences”  the document says.

The current demand for cryptocurrencies that have covered virtually all kinds of human activity appears to affect the Bank of America in a bad way, since he has banned any purchases of cryptocurrency for bank card holders since the beginning of this month, even taking into account the risk of losing a certain part of his customers.

“Clients may choose to conduct business with other market participants who engage in business or offer products in areas we deem speculative or risky, such as cryptocurrencies,” the bank said. Such increased competition may “negatively affect our earnings” or affect “the willingness of our clients to do business with us”, the bank said in a statement.

Nevertheless, Bank of America is actively studying blockchain technology, which is the basis of any cryptocurrency, and has the largest number of patents in this area, namely 45.

Among other risks for banking activities, which cryptocurrency promises, the report also says that such new technologies may limit the ability to comply with the rules of combating money laundering.

The Co-Founder of Apple Announced the Launch of His Own Blockchain-Based Project 213

interview with steve wozniak

Steve Wozniak, the co-founder of Apple, took part in an exclusive interview at the conference ChainXchange and talked about his attitude towards Bitcoin and cryptocurrencies in general and also shared his plans for the blockchain technology:

I like to keep up with things… Bitcoin caught my attention. It had so many unusual aspects for any technology I had ever heard of. Nobody is really known to be the creator. It doesn’t have any centralized [component]. It’s based on mathematics. There’s a certain number of Bitcoin that can ever exist… Mathematics to me is like nature. It’s much better than human beings… I trust those things of nature more than what man makes up. Man makes up currencies, controls them, issues new US dollars every year; Bitcoin was immune to that.

We want to point out that the famous American inventor, electronic engineer and programmer was not particularly interested in the subject of cryptocurrency in the fall of 2017 and even sold all his Bitcoins. Back then he found that cryptocurrencies only brought “anxiety”, but now, he seems to have learnt more things about the advantage of the blockchain technology:

At first I kept hearing [about blockchain], and I didn’t understand it. It’s not something you understand in a day. You think about it, read more about it and how it works, and then you see how people actually start to use it, through the mining process and also the verification and, aha! It all adds up!” said Wozniak.

After that, the co-founder of Apple made a sensational statement: he himself is going to start working with blockchain. According to him, this will happen “very soon”, the project is likely to be launched in Malta:

I’m involved with, very soon, my first time being involved in a blockchain company. [It’s] called Equi… Our approach is not like a new currency, or something phony where an event will make it go up in value. It’s a share of stock, in a company. This company is doing investment by investors with huge track records in good investments in things like apartment buildings in Dubai. We have one person in our group who has listed out a whole apartment building for Bitcoin… We might be starting up in Malta around the time of their blockchain conference. Some countries are very positive about [blockchain]the same way they were about electric vehicles.

Ripple Wonders Why The SEC Has Not Come Up with Cryptocurrency Status Yet 329

crypto status

We all remember the loud statement of the Securities and Exchange Commission which clearly said that the world’s two most popular digital coins (Bitcoin and Ethereum) do not comply with the definition of a security. What about other altcoins?

The representative of Ripple contacted the SEC not so long ago, asking why they have not yet determined the official status of cryptocurrencies. In response, the Commission’s spokesperson stated:

The SEC has not made a determination as to whether any specific cryptocurrency may be deemed a ‘security’ under the federal securities laws.

This answer is not quite informative, thus, we only have to wait upon the decision of the SEC.

We remind you that the SEC will take the decision concerning Bitcoin ETF in September of this year.

What Does John McAfee Have to Say About Bitfi, His Future Projects and Crypto in General? 514

interview with john mcafee

John McAfee is a very eccentric but still popular crypto personality. His every action and word instantly draws attention. Thus, we absolutely could not miss an interview that he gave to ETHNews discussing a couple of important issues.

Firstly, McAfee addressed the infamous story with Bitfi which we have thoroughly covered on our news portal. Many people were confused by McAfee’s behavior, thinking that he lied to all of his followers and customers. However, the “accused one” had an explanation for that:

My job is to market this thing [Bitfi]. How better to market it than to create a controversy?

Basically, McAfee admitted that he intentionally started all this drama with Bitfi to attract more attention to his wallet.

The crypto enthusiast also talked about a new big project – his own version of the CoinMarketCap, called McAfee Market Cap, and the further development of a decentralized crypto exchange. Though the program was launched, the developers had to take it down to introduce some upgrades and improvements.

Of course, the topic of possible running for presidency was not left out of the conversation. Here McAfee claimed that he is not interested in being the US President, he only intends to run for the post. According to him:

The act of finding and creating the president – that’s what changes America. So I want to be involved in that.

Overall, McAfee is very satisfied with everything he’s currently doing and the influence that he has on the financial world. He even modestly called himself “one of the premier technologists of this world”. However, only the time will show whether his ambitious plans will come true.

A Crypto Movie with Kurt Russell Will Soon Come Out 488

crypto movie

As we reported earlier, Hollywood started working on a film directly involving the topic of cryptocurrency. The producers have recently disclosed a couple of interesting details about this movie, besides its star-studded cast.

The plot of this thriller will wheel around the complicated world of money laundering, fraudulence and scams involving digital currencies. The main character, played by Beau Knapp, is going to unravel the dark secrets of this world.

The producers admit that they don’t have enough knowledge about crypto and trust specialists to handle the technical part, however, they have overall positive comments about it:

We hope it lasts for a long time…That’s one of the reasons why we wanted to do the film. We’re not into fads. We hope it stays around for a long time.

The official release of the movie is scheduled for 2019.

Blockchain Transactions: How Do They Work and How to Track Them? 832

blockchain transactions

Satoshi Nakamoto, the creator of Bitcoin, published an article “Bitcoin: A Peer-to-Peer Electronic Cash System” in 2008 and introduced a fundamentally new way of exchanging money. From that moment on, the need for a third party, like a bank or other financial institution, simply disappeared. In fact, this has become a new financial revolution.

Today we will talk how blockchain transactions are conducted from a technical point of view, how reliable they are, what features they have and how they can be tracked.

  2. How are transactions organized?
  3. What features do blockchain transactions have?
  4. How to test a blockchain transaction?
  5. The reasons why transactions can freeze
  6. Conclusion

1. How does blockchain work in general?

We should start with the fact that Bitcoin is the first ever completely digital currency. Unlike electronic money, it does not exist even as a digital file. It is a huge stream of data about all the transactions that have ever been conducted. Blockchain is presented in the form of a giant accounting book, which is available to all network participants.

Each transaction is not stored separately, the information is placed in the blocks. Different networks have different block sizes, for example, until recently one block in the network of Bitcoin “weighed” 1 MB. But the BitMEX report says that after the introduction of the new SegWit protocol, the average size of one block has increased to 1.06 MB, and some have reached 2 MB.

In order to obtain a new block, there are different mechanisms for consensus. The most widespread ones are:

  • PoW (proof of work). Here, the miners need to solve a complex cryptographic equation. After that, a new block is added, for which the system rewards the finder with a certain number of coins.
  • PoS (proof of stake). This mechanism involves adding a new block to a user who has a certain number of coins. The more coins a user has, the more likely he/she will generate a new block.

Each subsequent block stores information about the previous one. Another important feature of blockchain is its decentralization, since information is simultaneously stored by all participants of the system (miners, master nodes). Thus, after the block is added to blockchain, it can not be changed or deleted.

2. How are blockchain transactions organized?

As it was mentioned above, transactions that are carried out in the network of blockchain do not require the participation of a third party. Let’s see how this happens in practice.

Let’s say you want to transfer 0.5 BTC to another person. Before the system recalculates the wallets’ balances (not transfer, namely, the recalculation), this transaction will fall into the so-called Memory Pool – the operational memory of all the miners connected to the network. After this, the blockchain transaction must be confirmed by at least 6 different miners. They (miners) should check the correctness of the transaction:

  • the amount of commission for each byte of information;
  • the physical possibility of adding a transaction to an existing block (if there is too little space left in the block, the transaction is transferred to the next one that still needs to be found).

After these actions, the data on the operation are permanently entered in the blockchain, and the coins are credited to the wallet of the recipient.

3. What features do blockchain transactions have?

Based on the abovementioned information, it is worth highlighting a number of features that are typical for blockchain transactions:

  • Irreversibility. Since the blockchain system is a decentralized system, it is not possible to affect the data that has already been entered in the register. Therefore, it is impossible to mark the already completed operation.
  • Lack of regulation. Due to the absence of the center from which the system is managed, it is impossible to completely prohibit and shut down cryptocurrencies. To do this, you must destroy all the computers of miners.
  • Anonymity. Each blockchain has its own level of anonymity, but in any case, even in pseudonymous anonymous networks, such as Bitcoin, for example, the names and surnames of users are never used for transactions.
  • Reliability. The network algorithm fixes the balance of all the wallets at the same time, but only a user who has a private key can make a transaction from a particular wallet. Subject to observance of elementary security rules, it is not possible to crack the wallet. You can lose your coins only because of your own fault. For example, if you send them to the wrong wallet, infect your computer or smartphone with a virus or somehow let scammers get private keys.

4. How to test a blockchain transaction?

Transactions in the Bitcoin network can be tracked on the site www.blockchain.info. In order to see information about a particular transaction, you need to go to this site and enter a unique transaction hash in the search bar. Then the system displays the actual information.

In this service you can also see information about a particular wallet:

  • transactions in the history (by dates);
  • the total number of coins that passed through the wallet;
  • the list of all addresses which there have ever been interactions with (incoming or outgoing operations);
  • current balance.

5. The reasons why transactions can freeze

The main problem of Bitcoin and many other coins is the speed of blockchain transactions. As for  BTC, this indicator reaches a mark of 7 operations per second. Previously, when the total number of users was small, this was enough. But now, with the growing popularity of the industry, the “line” for the transaction can turn into tens and even hundreds of thousands of unconfirmed operations. You can view the current list, which is updated in real time, on this service.

Some transactions may even freeze in the Memory Pool for a long period of time (up to 72 hours). What factors affect the speed of transaction confirmation?

  • Total pool load.
  • A very small commission. Miners confirm transactions with a larger commission in the first place.
  • The transaction weight is too big, and it simply does not fit into the almost completely filled block. In this case, it will be automatically transferred to the next one.

6. Conclusion

Cryptocurrencies have made a real revolution in the financial sector, on a scale that we still can not comprehend. The number of blockchain transactions is growing every year. In order for everyone to be able to use Bitcoin at the same time (like Visa, for example), it is necessary to solve the problem with bandwidth.

Blockchain transactions have both their advantages: the absence of intermediaries, small commissions, anonymity, security, and their shortcomings: irreversibility, low throughput.
