Hard Forks Overview, How It Works, History

what is a hard fork

The blockchain network then abandons the blocks that are in the shorter chain, referred to as orphaned blocks. The miner that mined the orphaned block loses the mining reward and transaction fees but no transactions would be affected as both blocks would have contained the same transactions. The proposal for a hard fork did not exactly unwind the network’s transaction history. Rather, it relocated the funds tied to the DAO to a newly created smart contract with the single purpose of letting the original owners withdraw their funds. As the graphic below displays, nodes that are not upgraded reject the new rules, which creates a divergence, or hard fork, in the blockchain.

Is Bitcoin Cash a Hard Fork?

Since the new cryptocurrency doesn’t have any of the value of the old one, the new cryptocurrency would start at a value of zero on until demand outstrips supply and moves the price up, if at all.

However, it differs in terms of the proof-of-work (PoW) algorithm it requires of miners.

Which Crypto Is a Hard Fork From Bitcoin?

Ethereum Classic (ETC) emerged as a result of the hard fork that occurred after the DAO hack in 2016. While the majority of the Ethereum community supported the hard fork to reverse the unauthorized transactions, a minority chose to remain on the original blockchain, which became Ethereum Classic. Sometimes, a hard fork can have a profound impact on a blockchain and cryptocurrency. It depends on the circumstances surrounding the fork and the sentiments of the community and developers. The simplest way to conceptualize a fork in a cryptocurrency’s blockchain is to imagine that the fork introduces a new set of rules for Bitcoin to follow. After a new rule is introduced, the users mining that particular blockchain can elect to follow one set of rules or another.

What is a Fork?

The impact here is clearly much larger and can require quite a bit of development from wallet providers. Hard forks are significant events that are widely publicized in the world of cryptocurrency and blockchain technology. During a hard fork, fully depreciated asset definition developers propose changes to the existing blockchain protocol. These changes can include modifications to the consensus mechanism, block size limits, transaction validation rules, or any other aspect of the blockchain’s functionality.

Hence after a hard fork, the original holders don’t lose any of their existing digital coin but instead will get a unit of the new crypto as well. Owners of DAO tokens were able to withdraw ETH at a ratio of around 1 ETH for every 100 DAO. To offer “failsafe protection” for the organization, the DAO curators withdrew and distributed any additional token balance and ether that existed after the hard fork. Bitcoin Cash forked from Bitcoin in 2017 after developers and the Bitcoin community disagreed on which direction Bitcoin changes should take the blockchain. Wright, who has claimed to be the pseudonymous Satoshi Nakamoto on numerous occasions, believed that the BCH software should expand the maximum block size from 32MB (megabytes) to 128MB. Wright argued that this change would be more in keeping with Satoshi’s original idea for Bitcoin; thus, the nickname “Satoshi’s Vision” was born.

  1. A hard fork is when nodes of the newest version of a blockchain no longer accept the older version(s) of the blockchain; which creates a permanent divergence from the previous version of the blockchain.
  2. Forks may be initiated by developers or members of a crypto community who grow dissatisfied with functionalities offered by existing blockchain implementations.
  3. Because the developers and community could not agree on whether increasing block size limits was worthwhile, one side created a fork, and the other continued operating as it had.

On the opposing side, small block proponents like Blockstream advocated for smaller blocks, with small transactions handled in off-chain solutions like the Lightning Network. Since the two sides could not agree, the large-block side used a hard fork to create a separate version of Bitcoin, although they failed to attract a majority of the original network’s nodes or miners. Hard forks necessitate a majority of the network’s hash power to adopt the new protocol, while soft forks only require a majority of the hash power to validate blocks according to the new rules. Accidental forks happen when two or more blocks are found at the same time, and it is resolved when subsequent blocks are added, and one of the chains end up being longer than the other.

Put simply, a hard fork is a change to the software protocol that makes previously invalid blocks/transactions valid, or vice-versa. It requires all nodes or users to upgrade to the latest version of the protocol software. As the cryptocurrency ecosystem continues to evolve, it is crucial to stay informed and adapt to changes. Whether you are a trader, investor, or enthusiast, keeping up with the latest developments in hard forks and other blockchain events can help you navigate the ever-changing landscape of cryptocurrencies. Since soft forks are less disruptive that a hard fork, soft forks are generally much preferred. In cases where there a fundamental change or a disagreement occurs, a hard fork is potentially messier as the network may become less secure and more vulnerable to attacks.
