Hard Fork: What It Is in Blockchain, How It Works, and Why It Happens

As the digital ledger is held by all nodes, it makes it very difficult to tamper with the blockchain and even harder to go back. Each one of these users, called a node, stores a copy of the blockchain database (also called a digital ledger). Any new entries to this digital ledger must be first agreed upon before being added to the blockchain.

• Additionally, faster blockchains are thought to be more appealing to users because they reduce the network lag between transactions, validation, and receiving funds.
• In 6 months the asset has lost about 60% of its value, dropping from 0.8 dollars per token to the current price of 0.32 dollars.
• Since a hard fork rejects any block that still uses the old rules, a hard fork effectively creates a new blockchain, network, and cryptocurrency.
• Although they are most politicized and talked about in contentious issues, hard forks are a fundamental aspect of updating a blockchain.
• It is not always an adverse event; in fact, many blockchains have undergone hard forks to implement necessary changes.
• ADA in turn could benefit from the increase in popularity of decentralized finance on the chain, and support an increase in demand in the market.

A Short Guide to Bitcoin Forks

In the latter instance, hard forks essentially reset the blockchain ledger by creating a new ledger that starts at a point in time before the hack happened. With that said, 2 of the most successful forks still in existence are Bitcoin Cash (trading under $BCH) and Bitcoin Gold (trading under $BTG). Bitcoin Cash aims to become a faster, more efficient version of Bitcoin through larger block sizes. Bitcoin Gold runs on a modified proof-of-work system with the goal of becoming even more decentralized than Bitcoin. Although they are most politicized and talked about in contentious issues, hard forks are a fundamental aspect of updating a blockchain.

This article will help you navigate all these various chains listed, and how they came to be. Hopefully, you have read it all and now you should have a really good understanding of what a fork is and the reasons why they happen. Before I continue, I want to mention a few important things that you should consider if you are holding Bitcoin and expecting some free coins from any upcoming Bitcoin forks. Although each movement of funds is still posted to the public ledger, both the sender and the receiver remain private. This is slightly different from the original Bitcoin, as although the real-world identity of the sender and receiver are not revealed, it is possible to find out how much a certain Bitcoin address has. Not only that, but you can also see how much a particular address has sent and received in the past.

As tensions rose, developers and miners within the BCH community increasingly moved toward supporting one or the other of two prominent personalities involved in Bitcoin Cash, Roger Ver and Craig Wright. Ver and Wright were both known as strong supporters of digital currencies, but they were unable to reach an agreement about how to proceed. Through the process of hard forking, the original cryptocurrency, Bitcoin Cash, remained in place and continued to follow its previous protocols. SV stands for “Satoshi’s Vision,” a reference to Bitcoin developer Satoshi Nakamoto.

They may also be created by a faction of the crypto community that wants to take a different direction with the blockchain. If you have read this Bitcoin Fork guide up to this point, you now have a bitcoin hard fork good idea of the most popular forks that have happened so far. Before we move on, take a look at the below comparison chart, which compares the main features of the different forked blockchains.

Other Famous Forks

However, most people use the term hard fork to describe a blockchain, cryptocurrency, developers, participants, and users that separate themselves from the original blockchain and network while using the altered version. The hard fork to create Bitcoin SV was motivated by the desire to increase the block size limit from 32 MB to 128 MB. Block size limits are important because the size dictates how much information can be packed into a block. Blocks can be thought of as cells in a spreadsheet that can only contain a certain number of characters.

BIP 101 proposed a block size increase from 1 – 8 MB, and then steadily increase thereafter to 24 tx/s. This change needed 75% of the network’s support for ~1000 blocks at the beginning of 2016. Understandably, it did not achieve this, and the change was not implemented. Hard forks are a change in programming that results in a blockchain split. Sometimes, hard forks are controversial in the community involved in a blockchain; at other times, they are necessary for a blockchain to progress.
