hashes that act as references to the previous block in the chain. The first block in a blockchain is called the <a href=https://www.bitdegree.org/"/crypto/learn/crypto-terms/what-is-genesis-block/">genesis block</strong></a>.</p>\n<p>Hashes act as a blockchain security feature. It is practically impossible to falsify the data recorded on the blockchain because it cannot be altered. Since <strong>each block holds a reference to the previous block</strong>, every single block would have to be altered to successfully falsify information.</p>\n<p>Any attempts to alter the information contained in a block are further complicated because blockchains are decentralized by design. This means that the <strong>blocks are not stored in a single location</strong>. Instead, the computer of each blockchain user acts as an individual <a href=https://www.bitdegree.org/"/crypto/learn/crypto-terms/what-is-node/">node of the overall network.</p>\n<p>The core information stored in a block is the transaction record, a timestamp, the hash, and an answer to a cryptographic puzzle. In order to add a new block to the chain, the puzzle must be solved first.</p>\n<p>The process of solving the block puzzle is referred to as <a href=https://www.bitdegree.org/"/crypto/learn/crypto-terms/what-is-mining/">mining. <strong>Mining a block typically grants the solver a reward</strong>. A typical example of a reward is miners receiving <a href=https://www.bitdegree.org/"https://www.bitdegree.org/crypto/buy-bitcoin-btc/">Bitcoin (BTC)</strong></strong></a> for solving a block on the Bitcoin blockchain. The transaction information and the addresses that claim the reward are the first data recorded in a new block.</p>\n<p>On the Bitcoin blockchain, the difficulty of solving each block puzzle is not even across the board. Every 2016 blocks, the network consensus adjusts the difficulty. It changes on a sliding scale, becoming either more or less complicated, to keep the mining system fair.</p>\n<p>&nbsp;</p>","level":"easy","meta_title":"What is Block?

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?

What is Block?

Block MEANING:
Block - a structural unit of a blockchain that contains information about a transaction.
Easy

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

A block is the most essential feature of a blockchain. New blocks are added to the end of the chain in sequential order. The blocks contain hashes that act as references to the previous block in the chain. The first block in a blockchain is called the genesis block.

Hashes act as a blockchain security feature. It is practically impossible to falsify the data recorded on the blockchain because it cannot be altered. Since each block holds a reference to the previous block, every single block would have to be altered to successfully falsify information.

Any attempts to alter the information contained in a block are further complicated because blockchains are decentralized by design. This means that the blocks are not stored in a single location. Instead, the computer of each blockchain user acts as an individual node of the overall network.

The core information stored in a block is the transaction record, a timestamp, the hash, and an answer to a cryptographic puzzle. In order to add a new block to the chain, the puzzle must be solved first.

The process of solving the block puzzle is referred to as mining. Mining a block typically grants the solver a reward. A typical example of a reward is miners receiving Bitcoin (BTC) for solving a block on the Bitcoin blockchain. The transaction information and the addresses that claim the reward are the first data recorded in a new block.

On the Bitcoin blockchain, the difficulty of solving each block puzzle is not even across the board. Every 2016 blocks, the network consensus adjusts the difficulty. It changes on a sliding scale, becoming either more or less complicated, to keep the mining system fair.
