Black Hat Hackers vs. White Hat Hackers</h2>\n<p>Black and <a href=https://www.bitdegree.org/"/crypto/learn/crypto-terms/what-is-white-hat-computer-hacker/">white hat hackers</strong></a> derive their names from the Spaghetti Western tropes. In these movies, good characters usually wore white hats, while the bad guys wore black ones. Therefore, the hat colors represent the intent of the hackers.</p>\n<p>Black hat hackers commit their attacks with the intent to steal data, assets, or otherwise cause harm to computer systems. They can jeopardize network security by directly altering data or removing it altogether. Black hat hacking is committed with criminal intent.</p>\n<p>White hat hackers are otherwise known as <strong>ethical hackers</strong>. They are computer experts hired by organizations to run checks on their systems by hacking into them, and expose vulnerabilities when they come across any.</p>\n<p>White hat hackers may test the penetrability of the computer system and install protective measures to reinforce network security. White hat hackers aim to get ahead of malicious actors like black hat hackers and patch any system issues before they are taken advantage of.</p>\n<h2>Other Hat Hackers</h2>\n<p>In addition to black and white hats, there are more colors on the hacking spectrum. As technologies advance, new hacker categories are established at varying levels of proficiency and driven by different intent.</p>\n<h3>Gray Hat Hackers</h3>\n<p>As the name suggests, gray hat hackers lie somewhere in the middle between black and white hats. Their intent may be murky. Gray hat hackers typically don&rsquo;t aim to make a profit from their attacks. Their actions may simply be driven by curiosity and wanting to explore the gaps in computer systems.</p>\n<p>However, gray hat hackers are not necessarily driven by ethical intent either. They may not report their discoveries of system gaps to the organization, thus leaving the opportunity for black hat hackers to break into the network. They do not feel the need to help people or organizations. Therefore, they are in the &ldquo;gray area&rdquo; of cybercrime.</p>\n<h3>Green Hat Hackers</h3>\n<p>Green hat hackers are referred to as such because they are still new to the field. They do not have the advanced skills and experience of black hat hackers, which makes them green in comparison.</p>\n<p>They are generally enthusiastic about developing their skills and improving their hacking abilities. They may seek out more experienced hackers as mentors. Whether they end up becoming black, white, or gray hat hackers depends on their personal intent.</p>\n<h3>Blue Hat Hackers</h3>\n<p>There are two definitions of blue hat hackers. Some define them as hackers who are seeking revenge from a particular company or an individual. The more common profile of a blue hat hacker is someone who does not have advanced hacking abilities. However, unlike green hats, they aren&rsquo;t interested in developing their skills further.</p>\n<p>Blue hat hackers may only develop enough knowledge to commit the attack on their target of vengeance and not commit any further cybercrime in the future.</p>\n<h3>Red Hat Hackers</h3>\n<p>Red hat hackers are sometimes described as <strong>vigilantes</strong>. Similar to white hats, red hat hackers aim to disarm black hats. However, red hats do not simply want to prevent a black hat from breaching a system. Their goal is to cause as much harm to black hats in the process as possible.</p>\n<p>Red hats may launch counter-attacks aimed at the systems used by black hat hackers. They attempt to destroy the software used by black hats and are often considered to be the most sophisticated category of hackers.</p>\n<h2>Other Hacker Types</h2>\n<p>Black hat hacking is only one form of hacking that is common in the digital world. Different types of hacking are distinguished based on their methodology and the aim of the hacker.</p>\n<p>Acquiring sensitive data and metadata, stealing financial assets, and spying on individuals or governmental organizations are a few of the common motives for hackers. White hat hackers are typically hired by organizations to expose system vulnerabilities or bugs.</p>\n<p>Some hackers are organized into groups and perform their attacks with political intent. These hackers are typically known as hacktivists. Organizations like Anonymous are known as hacktivist movements.</p>","level":"hard","meta_title":"What is Black Hat Hacker?

That&rsquo;s because it has a negative impact on investments and the market in general.</p>\n<p>The phrase Black Swan Event could have come from a Latin phrase said by Juvenal, the Roman poet, in the 2nd century. The Latin phrase he said means &ldquo;an unusual bird in the lands that looks a lot like a black swan&rdquo;. For a long time, it was thought that black swans do not exist. Later on, the name of these birds was used when talking about something that comes as a surprise.</p>\n<p>The term was first used by a writer and finance professor, as well as the former Wall Street trader, Nassim Nicholas Taleb. To be precise, the writer talked about the term in his book. The book was written in 2007. He emphasized the importance of preparing for anything unpredictable to happen and planning ahead.</p>\n<p>The probability of its occurrence is unknown. However, when it happens it has a big negative impact. Those who observe the event and the aftermath, are known to be speculating as to what could have prevented it and how it could have been predicted. Moreover, the event can be explained only in retrospect.</p>\n<p><em>When a black swan event happens in the field of finances and cryptocurrency it results in huge misery and destruction.</em></p>\n<p>As an example, consider <strong>the 2001 dotcom bubble</strong>. This occurred during a period of rapid economic expansion in the United States, as well as a surge in private wealth before everything spectacularly crashed. At the time, investment funds were pouring money into technology firms with exorbitant valuations and no market traction.</p>\n<p>Then these firms went bankrupt, and the negative risk was transferred to the investors.</p>\n<p>A similar situation happened in 2008, amid a financial crisis when the housing market in the United States collapsed. The repercussions were massive and far-reaching. People with poor or no credit were approved for mortgages on homes that were much beyond their financial limits.</p>\n<p>At the same time as payment deadlines passed and mortgages began to default in droves, the lending powerhouses began to fail.</p>\n<p>The U.S. government then approved the TARP (Troubled Asset Relief Program). To be more specific, approximately <strong>$1 trillion</strong> was invested to assist large banks and reestablish liquidity in the economy. Furthermore, the regulations were modified in the hopes that this black swan incident would not occur again.</p>\n<p>The most recent example is the COVID-19, which hit the world without warning. There was no one prepared or equipped to deal with the epidemic. Therefore, it had a significant influence on stock market crashes, unemployment rates, business failures, and so on.</p>\n<p>To be fair, COVID-19 fulfilles all of the criteria for a black swan occurrence.</p>","level":"medium","meta_title":"What is Black Swan Event?

Let's find out Block Explorer meaning, definition in crypto, what is Block Explorer, and all other detailed facts.

A blockchain browser is another name for a block explorer. Each unique block offers information about a specific blockchain.

Bitaps, Blockstream, Multihash, Blockchain Info, and Bitupper Explorer are a few of the most well-known block explorers that can be found online. These explorers aim at the last blocks that are about to be added.

Moreover, users can’t gain data about Ethereum and Bitcoin by using one explorer, since each blockchain needs a separate one.

Block explorers are considered to be a valuable tool for making cryptocurrencies coherent and decentralized. It’s because it assists in making all transaction information visible.

Because of its potential value, the search software is advantageous to miners, validators, and enterprises. When purchasing or selling cryptocurrency, the explorer may be used to verify the status of transactions.

Additionally, it’s a great tool for miners for checking if they’ve successfully mined a block.

The information that users get includes the block height, the block reward, the age of the block, the TX indicating the number of transactions in the block, the user's identity, and the status.

To utilize a block explorer to look for information about a specific block, enter the transaction hash or ID into the search field. The explorer will next determine whether or not your transaction has been verified.
