These divisions can result in debates, disagreements, and the formation of separate communities with different visions and objectives. Another notable hard fork event occurred in 2016, involving the Ethereum network. The Decentralized Autonomous Organization (DAO), a smart contract-based investment fund built on the Ethereum blockchain, was hacked, resulting in the theft of millions of Ether (ETH). Hard forks can be initiated by developers or members of a cryptocurrency community dissatisfied with the existing functionalities provided by current blockchain implementations. They can also crowdsource funding for new technology projects or cryptocurrency offerings. This was before the SegWit soft fork (more on that shortly), so nodes would only accept blocks smaller than 1MB.
- However, a blockchain hard fork usually results in two distinct ledgers and transaction networks—effectively creating a new cryptocurrency.
- The implementation of a hard fork can have significant implications for the blockchain.
- They may also emerge as a way to crowdsource funding for new technology projects or cryptocurrency offerings.
- They can have a significant impact on the market, causing price volatility and community divisions.
- In fact, many of what we consider to be cryptocurrency users don’t take on any of these roles.
One common reason is to add new functionality or improve the performance of the blockchain. Developers might introduce a hard fork to address security issues, adjust the protocol rules, or scale the network. Sometimes, when the community can’t reach a consensus on a proposed upgrade, it may lead to a split, with one part of the network adhering to the old rules and the other adopting the new ones. Hard forks are a fascinating aspect of the cryptocurrency world, enabling the creation of new blockchains and cryptocurrencies. They can have a significant impact on the market, causing price volatility and community divisions. Understanding the mechanics and implications of hard forks is essential for anyone interested in cryptocurrencies.
What reasons can trigger a Hard Fork?
This created a huge amount embarrassment for the fledgling Ethereum, but the hard fork changed the perception that cryptocurrencies were immutable. 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. Some bitcoin forks, including Bitcoin Gold, have attempted to make bitcoin more accessible by changing the hardware necessary to establish a network connection. Bitcoin Gold was a hard fork that followed shortly after bitcoin cash, in October 2017. The creators of this hard fork aimed to restore the mining functionality with basic graphics processing units (GPU), as they felt that mining had become too specialized in terms of equipment and hardware required. Hard forks often have a significant impact on the price volatility of cryptocurrencies.
While this cannot be altered, the rules which a specific blockchain operates by can to an extent. These updates, known as blockchain forks, can play an important role moving forward. Hard forks and soft forks are essentially the same in the sense that when a cryptocurrency platform’s existing code is changed, an old version remains on the network while the new version is created. It is through this forking process that various digital currencies with names similar to bitcoin have been created. For the casual cryptocurrency investor, it can be difficult to tell the difference between these cryptocurrencies and to map the various forks onto a timeline.

In 2016, about a year after the Ethereum network was launched by Vitalik Buterin, an organization launched an investor-directed venture capital fund on the Ethereum network. This organization was called “The DAO” and was the first “Decentralized Autonomous Organization”, so it is also known as the Genesis DAO.
Nodes that have adopted the new protocol continue to validate and propagate transactions according to the updated rules, while nodes that have not upgraded remain on the old protocol. A https://www.tokenexus.com/ in the crypto space refers to a situation where the existing blockchain protocol undergoes a significant upgrade or modification, leading to the creation of a new and separate blockchain. This upgrade can be the result of various factors, such as improving network speed, addressing security vulnerabilities, or introducing new features to enhance functionality.
Hard forks vs. soft forks – which is better?
Despite all the benefits that the SegWit proposal offered, not everyone was happy when BIP 91 was implemented in on block 477,120 in a soft-fork. While it might seem like you’ve just been given a new cryptocurrency for free, this does come at a cost. It might come with a decrease in network stability – thus security – since the network becomes smaller due to the split. DAO token holders could withdraw ETH at a rate of approximately 1 ETH to 100 DAO. The extra balance of tokens and any ether that remained as a result of the hard fork was withdrawn and distributed by the DAO curators to provide “failsafe protection” for the organization.
In the years following the genesis block, there have been several hard forks. In 2009, shortly after releasing bitcoin, Satoshi mined the first block on the bitcoin blockchain. This has come to be referred to as the Genesis Block, as it represented the founding of the cryptocurrency as we know it. Satoshi was able to make numerous changes to the bitcoin network early on in this process; this has become increasingly difficult and bitcoin’s user base has grown by a tremendous margin. Bitcoin Cash (BCH) is a prominent example of a hard fork that occurred within the Bitcoin network. It was created in 2017 to address scalability issues and increase the block size limit from 1MB to 8MB.
