Cardano_(blockchain_platform)/" target=\"_blank\" rel=\"nofollow noindex noopener\"><strong>Cardano</strong></a>&nbsp;ecosystem to combine protocols after a <a href=https://www.bitdegree.org/"/crypto/learn/crypto-terms/what-is-hard-fork-blockchain/">hard fork</strong></a> event.</p>\n<p>A hard fork splits one <a href=https://www.bitdegree.org/"/crypto/learn/crypto-terms/what-is-blockchain/">blockchain into two distinguishable protocols which run parallel to each other. The new blockchain branch loses the history of the prior blockchain. A hard fork occurs when new upgrades are implemented into the blockchain. It can modify some of the protocol parameters.</p>\n<p>Hard forks may also occur <strong>on the live blockchain</strong>, which can compromise the integrity of the network. In 2017, a hard fork occurred on the <a href=https://www.bitdegree.org/"https://www.bitdegree.org/crypto/buy-bitcoin-btc/">Bitcoin blockchain</strong></a>, leading to the <strong>chain split</strong>. The event had a significant impact on the interests of Bitcoin investors and caused the formation of Bitcoin Cash (BCH).</p>\n<p>Hard forks often cause downtime in the blockchain ecosystem which can negatively impact the user experience and disrupt any <strong>ongoing</strong> transactions. If a hard fork occurs, the <a href=https://www.bitdegree.org/"/crypto/learn/crypto-terms/what-is-node/">network nodes</strong></a> are unable to update to the newly set parameters and <a href=https://www.bitdegree.org/"/crypto/learn/crypto-terms/what-is-block-header/">block headers</strong></strong></a> simultaneously, without experiencing system interruptions. The blockchain then has to be taken into downtime.</p>\n<p>Although a hard fork may occur on any blockchain, <a href=https://www.bitdegree.org/"/crypto/learn/crypto-terms/what-is-input-output-hong-kong-iohk/">IOHK developed the hard fork combinator as a solution specifically for the <strong>Cardano ecosystem</strong>. The hard fork combinator merges both the pre and post-upgrade protocols together to eliminate the possible interruption or restart issues.</p>\n<p>With the hard fork combinator, several protocols can appear as a single <a href=https://www.bitdegree.org/"/crypto/learn/crypto-terms/what-is-ledger/">ledger. This <strong>prevents the network nodes from having to update</strong> to the new blockchain simultaneously.</p>\n<p>In July 2020, Cardano received upgrades, moving from the wallet-only Byron protocols to proof-of-stake-supported Shelley protocols. During the upgrade, the utility of the blockchain was altered by the hard fork.</p>\n<p>This was a <strong>risky procedure</strong>, as Cardano contained over 1 million <a href=https://www.bitdegree.org/"/crypto/learn/crypto-terms/what-is-wallet/">wallets at the time. Any issues with the hard fork execution could have been detrimental to the Cardano ecosystem as a whole.</p>\n<p>The <strong>Byron-to-Shelley transition was successfully completed</strong> on 29 July 2020, at 21:45 UTC. Users received notice about the ongoing upgrade. However, the use of the Cardano function was not restricted and the hard fork processes were completed in the background. This allowed the network nodes to transition between protocols sequentially.</p>\n<p>Thanks to the <strong>hard fork combinator</strong>, the Cardano blockchain has been able to maintain both Byron and Shelley blocks. The tool will be implemented in future upgrades to support the transitional process.</p>","level":"medium","meta_title":"What is Hard Fork Combinator?

Cold wallets store private keys natively, offering reinforced security from malicious code. Private keys are used to identify the owner of the assets stored in the wallet. They also allow holders to transfer their crypto assets to and from the wallet.</p>\n<p>Hardware wallets come with two key security features &ndash; <strong>a secure PIN code and a <a href=https://www.bitdegree.org/"/crypto/learn/crypto-terms/what-is-seed-phrase/">seed phrase</a></strong>.</p>\n<p><strong>The seed phrase</strong> is required to access the wallet if the user has lost their PIN. Even if a wallet is stolen, it's nearly unhackable, as most models will reset and burn any stored assets if the seed phrase is entered incorrectly multiple times.</p>\n<p><strong>The PIN</strong> is the most frequently used security measure as the user must enter it to access the contents of the wallet. Furthermore, users should keep their physical wallets in a secure place to avoid losing them or having them stolen.</p>\n<p>Cold wallets can be used to sign any outgoing transactions. While the security measures are nearly fool-proof, the wallets themselves are easy-to-use for new investors or people who are not as tech-savvy.

It can be grounded for ideological reasons or personal gain. Hackers may use different strategies and technologies to achieve their goals.</p>\n<h3>Brute Force Attack</h3>\n<p>A <a href=https://www.bitdegree.org/"/crypto/learn/crypto-terms/what-is-brute-force-attack-bfa/">brute force attack</strong></a> is a method of trying to crack a password or any encrypted information via automated guessing. Hackers employ <a href=https://www.bitdegree.org/"/crypto/learn/crypto-terms/what-are-bots/">bots that attempt to guess as many combinations of passwords as possible.</p>\n<p>The simpler the password is, the shorter the brute force attack lasts. Short passwords that contain only letters are considered weak, and it is recommended to add more characters to reinforce their security. Long passwords containing both <a href=https://www.bitdegree.org/"/crypto/learn/crypto-terms/what-does-alphanumeric-mean/">alphanumerics and special symbols are much more robust and sometimes may take millions of years to crack.</p>\n<h3>Cryptomining malware</h3>\n<p>Cryptomining malware is a relatively new method of hacking. If a user&rsquo;s computer is infected with this type of <a href=https://www.bitdegree.org/"/crypto/learn/crypto-terms/what-is-malware/">malware, it unwillingly becomes part of a crypto mining network. This can disrupt processes, cause internet speeds to slow down, and may lead to the hardware deteriorating faster.</p>\n<p>Cryptomining malware can be caught by downloading infected files or visiting suspicious websites. The process is also known as <a href=https://www.bitdegree.org/"/crypto/learn/crypto-terms/what-is-cryptojacking/">cryptojacking.

/n

Distributed Denial of Service (DDoS)</h3>\n<p><a href=https://www.bitdegree.org/"/crypto/learn/crypto-terms/what-is-distributed-denial-of-service-ddos-attack/">Distributed denial of service (DDoS)</strong></a> attacks are used to prevent users from accessing certain websites. Unlike some of the other methods listed here, DDoS attacks have to be coordinated and performed <strong>by a large number of participants</strong>.</p>\n<p>DDoS attacks are often done on a political basis. They may be used to cover information or prevent users from accessing websites of high importance. DDoS attacks are often coordinated against cryptocurrency platforms to destabilize them.</p>\n<h3>Keylogging</h3>\n<p><a href=https://www.bitdegree.org/"/crypto/learn/crypto-terms/what-is-keylogger/">Keylogging is a <a href=https://www.bitdegree.org/"/crypto/learn/crypto-terms/what-is-spyware/">spyware method. If a user&rsquo;s computer is infected with keylogging software, the hacker is able to see every character that the <strong>user types on their keyboard</strong>. This can reveal passwords, private messages, and other sensitive information.</p>\n<p>Keylogging can also affect mobile devices. Some apps that provide additional emojis or keyboard themes for the device have been proven to be keylogging spyware. Third-party text editing apps sometimes may also log the keyboard presses for unclear intents.</p>\n<h3>Phishing</h3>\n<p><a href=https://www.bitdegree.org/"/crypto/learn/crypto-terms/what-is-phishing/">Phishing involves a hacker setting up a fraudulent malware-infected website that appears legitimate. A user is tricked into clicking the link as logging into the website, which leads to the computer getting infected. The hacker can then access the files on the victim&rsquo;s computer, including login details and any other sensitive information.</p>\n<p>Phishing attacks are commonly used in the crypto world. In January 2022, the online platform Crypto.com admitted that <a href=https://www.bitdegree.org/"https://www.vice.com/en/article/g5qj9j/cryptocom-says-incident-was-actually-dollar30-million-hack/" target=\"_blank\" rel=\"nofollow noindex noopener\"><strong>$30 million worth of cryptocurrency was lost in a phishing attack</strong></a>.</p>\n<h3>Ransomware</h3>\n<p>As the name implies,&nbsp;<a href=https://www.bitdegree.org/"/crypto/learn/crypto-terms/what-is-ransomware/">ransomware involves <strong>extortion</strong> and is used for financial gains. The files on an infected computer are <a href=https://www.bitdegree.org/"/crypto/learn/crypto-terms/what-is-encryption/">encrypted. Hackers demand victims to pay a ransom for the files to be <a href=https://www.bitdegree.org/"/crypto/learn/crypto-terms/what-is-decryption/">decrypted and accessible.</p>\n<p>Ransomware can be caught by downloading suspicious files or software. However, this method of hacking is on the decline as many hackers have moved onto using cryptomining malware.</p>\n<h2>Black Hat vs White Hat Hacking</h2>\n<p>Hacking is most commonly done with malicious intent, such as terrorism, money laundering, or means to illegally sell data. However, in some cases, hacking may be done for a good cause. This disparity has led to the concept of black hat and white hat hackers.</p>\n<p><a href=https://www.bitdegree.org/"/crypto/learn/crypto-terms/what-is-black-hat-hacker/">Black hat hackers</strong></a> attack systems maliciously. Their goal is to disrupt the network for personal, usually financial gain. They are known as highly skilled computer experts that can cause severe damage to computer systems.</p>\n<p><a href=https://www.bitdegree.org/"/crypto/learn/crypto-terms/what-is-white-hat-computer-hacker/">White hat hackers</strong></strong></a> are also known for their excellent skillset. However, they perform hacks with good intentions. They are often hired by companies to find if there are any exploits in their systems. They work on discovering bugs or any entrance points that black hat hackers may find and patch them before the systems are breached.</p>\n<h2>Hacking in the Crypto Industry</h2>\n<p>Hacking is an ever-growing issue in the crypto industry. Hackers target blockchain-based systems due to the possibilities of exploitation. Some <strong>cryptocurrencies</strong>, like <a href=https://www.bitdegree.org/"https://www.bitdegree.org/crypto/buy-bitcoin-btc/">Bitcoin (BTC)</strong></a> or <a href=https://www.bitdegree.org/"https://www.bitdegree.org/crypto/buy-ethereum-eth/">Ethereum (ETH)</strong></a>, are valued at thousands of dollars for a single coin, making them a lucrative catch for malicious actors.</p>\n<p><a href=https://www.bitdegree.org/"/crypto/learn/crypto-terms/what-is-hot-wallet/">Hot wallets</strong></a> are a particularly common target. Since hot wallets require an internet connection to access the crypto assets, hackers may employ methods such as keylogging or phishing to gain access to users&rsquo; wallet addresses and claim the funds for themselves.</p>","level":"hard","meta_title":"What is Hacking?

What is Hard Fork Combinator?

Hard Fork Combinator MEANING:
Hard Fork Combinator - a tool used to combine protocols on the Cardano blockchain if a hard fork has occurred.

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

A Hard Fork Combinator is a tool used in the Cardano ecosystem to combine protocols after a hard fork event.

A hard fork splits one blockchain into two distinguishable protocols which run parallel to each other. The new blockchain branch loses the history of the prior blockchain. A hard fork occurs when new upgrades are implemented into the blockchain. It can modify some of the protocol parameters.

Hard forks may also occur on the live blockchain, which can compromise the integrity of the network. In 2017, a hard fork occurred on the Bitcoin blockchain, leading to the chain split. The event had a significant impact on the interests of Bitcoin investors and caused the formation of Bitcoin Cash (BCH).

Hard forks often cause downtime in the blockchain ecosystem which can negatively impact the user experience and disrupt any ongoing transactions. If a hard fork occurs, the network nodes are unable to update to the newly set parameters and block headers simultaneously, without experiencing system interruptions. The blockchain then has to be taken into downtime.

Although a hard fork may occur on any blockchain, IOHK developed the hard fork combinator as a solution specifically for the Cardano ecosystem. The hard fork combinator merges both the pre and post-upgrade protocols together to eliminate the possible interruption or restart issues.

With the hard fork combinator, several protocols can appear as a single ledger. This prevents the network nodes from having to update to the new blockchain simultaneously.

In July 2020, Cardano received upgrades, moving from the wallet-only Byron protocols to proof-of-stake-supported Shelley protocols. During the upgrade, the utility of the blockchain was altered by the hard fork.

This was a risky procedure, as Cardano contained over 1 million wallets at the time. Any issues with the hard fork execution could have been detrimental to the Cardano ecosystem as a whole.

The Byron-to-Shelley transition was successfully completed on 29 July 2020, at 21:45 UTC. Users received notice about the ongoing upgrade. However, the use of the Cardano function was not restricted and the hard fork processes were completed in the background. This allowed the network nodes to transition between protocols sequentially.

Thanks to the hard fork combinator, the Cardano blockchain has been able to maintain both Byron and Shelley blocks. The tool will be implemented in future upgrades to support the transitional process.
