The fork was a technical response to a critical vulnerability and a test of the community’s values, influencing Ethereum’s governance and future direction. The DAO Fork is the most significant hard fork in the early years of Ethereum. It was executed on July 20, 2016, due to a DAO (Decentralized Autonomous Organization) attack, which led to the loss of 3.6 million ETH. The world of cryptocurrencies is constantly finding new and different ways to develop and advance, whether it be from a technological perspective or information-wise.

This results in significantly lower transaction fees for users of layer 2 rollups. While we can’t say for sure, the deflationary mechanisms could raise the price of ETH. Such expectation could be related to the fact that, after the update, Ethereum has begun burning the ETH base fee of all blockchain transactions. If a block becomes more than 50% full with transactions, the base fee increases and vice versa.

It also creates the risk of double spending in what is called a “Replay Attack”, where a bad actor can intercept a transaction one fork and repeat it on the other chain, making them both valid. If you are using an Ethereum client that is not updated for the upcoming hard fork, your client will sync to the pre-fork blockchain once the fork occurs. You will be stuck on an incompatible chain following the old rules and you will be unable to send ether or operate on the post-fork Ethereum network. Now, however, the Ethereum Network is about to get another two important upgrades. Within the coming months, the Ethereum Network will introduce both the Ethereum Berlin Hard Fork and the London Hard Fork.

There will suddenly be thousands and thousands of mining rigs, GPUs, ASICs, and other cryptocurrency mining-related devices that will no longer serve a use. Byzantium was a phase which aimed to make the Ethereum platform more secure and better optimized. This was done one step at a time, but the initial goal was to make the network safer and more fluid to use. It’s not as extreme as Ethereum Classic – this one is aimed towards improvement rather than a revolution. The main reason why we’re specifically talking about Ethereum HARD forks is that they are so detrimental and significant to Ethereum’s well-being, that it becomes impossible to ignore. Some miners refused to fork because the DAO incident wasn’t a defect in the protocol.
- The Istanbul hard fork, activated on December 8, 2019, at block 9,069,000, aimed at increasing the network’s compatibility with other protocols.
- It was eventually followed by other notable updates during 2020, like that of the Ethereum Muir Glacier upgrade, the launch of the Medalla testnet, and the Ethereum 2.0 Beacon Chain.
- It introduced the “difficulty bomb,” which one year later, would ease a transition from Proof-of-Work (PoW) to Proof-of-Stake (PoS).
- Without this, there could be a chance that miners continue using Ethereum 1.0, similar to the split seen with Ethereum and Ethereum Classic.
Interestingly, some have speculated that this hard fork might not focus as much on features in the same way that the Berlin and London fork will. Instead, the Shanghai fork might revolve around the Ethereum 2.0 merge. To understand EIP-3238, we first need to understand what the Ethereum ”Difficulty Bomb” is. The Ethereum Difficulty Bomb is a part of Ethereum that raises the difficulty level of Ethereum Proof of Work puzzles. As such, this would result in longer-than-normal block times, effectively cutting the current rate of ETH rewards for Ethereum miners. Ethereum’s Berlin Hard Fork is the next upcoming update to the Ethereum Network.
While the change didn’t address transaction costs and speed issues, Ethereum made a significant leap toward network sustainability, security, and scalability. By introducing the Beacon Chain, Ethereum showed commitment to the shift from energy-intensive mining to staking. In this system, validators lock up ETH to participate in block validation, enhancing security and decentralization.
- This makes sense because there are usually no legitimate reasons to implement a hard fork in a normally functioning cryptocurrency.
- Increases in block difficulty of the proof-of-work consensus mechanism threatened to degrade the usability of Ethereum by increasing wait times for sending transactions and using dapps.
- 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.
- Now, the likelihood of a decrease in transaction prices and times is much more likely, but still not guaranteed.
- It added support for “sync committees”—enabling light clients, and increased validator inactivity and slashing penalties as development progressed towards The Merge.
- The Deneb upgrade contains a set of improvements to Ethereum’s consensus aimed towards improving scalability.

It’s often omitted for the second phase, as Bellatrix was just a preparation upgrade. It includes changes in the validator penalty values, expanded settings for the transition, and Merge instructions for ETH developers. Ethereum implemented https://www.tokenexus.com/ staking after block 11,052,984 and October 14th of 2020. It was a quick yet essential update to speed up the upcoming Beacon Chain (ETH2). Users could send amounts to this contract and start staking as soon as the new chain launched.
Hard Forks vs. Soft Forks
Back then, Ethereum was working on a future “merge,” as it was still using PoW and PoS at once. The difficulty bomb would ease the transition to PoS, and Altair was the last big update needed to set an official Merge date. On October 18th of 2016, Tangerine Whistle came in response to the previous month’s DoS spam attacks. Proposals EIP-150 and EIP-158 led to this hard fork, effective from block 2,463,000. At that time, Ethereum averaged $12 and crossed 84M in circulating supply.
Shiba Inu’s [SHIB] Shibarium recently underwent a hard fork that was aimed at improving the overall ecosystem. In fact, the latest upgrade was an effort to further strengthen the ecosystem’s deflationary characteristics too. Ethereum developers set a target date of April 12 Ethereum Hard Fork for its long-awaited Shanghai hard fork during the All Core Developers Execution Layer #157 call Thursday. Bellatrix took place on September 6th of 2022 after epoch 144,896 (around block 15,485,000). It was the second Beacon Chain upgrade and the first phase of the Merge.
