These forks become temporary ones – some miners may choose to use them, while others can just reject the change and continue mining the older versions of the coin. Also, before moving further, you should be aware of the fact that cryptocurrencies must be stored in a safe place at all times. So, always choose the most secure and reliable crypto wallets, or, alternatively, top-rated exchanges, such as Binance, Coinbase, and Kraken. The community seems unanimous—according to Ethereum’s publicly available Github code, a hard fork is tentatively scheduled for July 20.

Soft forks are typically minor changes or patches that don’t drastically impact the network and its users. Hard forks are more significant changes that create a new version of the blockchain. With soft forks, a change is made to the software protocol that doesn’t clash with the code and old nodes might accept data that appears invalid to the new nodes without the user noticing.
- Byzantium’s changes paved the way for future scaling solutions, diminished ETH inflation, and introduced new functionalities enabling more complex smart contracts and DApps to be built on Ethereum.
- With the introduction of blobs, gas fees could be reduced by up to 90%, making transactions much more affordable for users.
- Under Ethereum’s proof-of-stake consensus mechanism, implemented in September 2022, ommer blocks are no longer an issue because only one block is proposed at a time.
- Ethereum Classic, EtherZero and Metropolis – these are the main three Ethereum hard forks, and we’ll talk about each of them to an extent.
- Ultimately, Ethereum’s developers followed through with their decision to implement the hard fork.
- After that, we’ll focus on the Ethereum forks – you’ll find out when they happened, what they changed and what the future holds.
Plus: The risks and rewards of Ethereum Improvement Proposal (EIP) 1559.
The Byzantium fork, executed on October 16, 2017, at block 4,370,000, was part of Ethereum’s two-stage network upgrade, Metropolis. The Homestead upgrade, which took place on March 14, 2016, https://www.tokenexus.com/ was the first planned hard fork on the network. It introduced several protocol improvements to enhance the system’s robustness, marking the departure from the beta phase of Ethereum.
Understanding Hard Forks
This hard fork is really not a hard fork in the traditional sense, Teku client project manager Ben Edgington pointed out. Rather, it’s a warmup before sharding and a merge of the Eth 1.x and Beacon Chain. 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. Previously, ommer blocks were not accounted for when the difficulty was adjusted.
Understanding Forks
The frontier thawing fork lifted the 5,000 gas limit per block and set the default gas price to 51 gwei. The difficulty bomb was introduced to ensure a future hard-fork to proof-of-stake. The London upgrade came as a recommendation of EIP-1559 and was aimed at changing the transaction fee model of the network. Before the update, smart contracts could throw an error, and the initiator would still be charged the gas fees for the entire transaction. Gas fees for smart contracts can be costly, so this update kept contract creators from losing gwei—the small ether denomination used to pay for transactions—for a contract that didn’t fully execute. Once enacted, miners will no longer receive income from transaction fees — instead, it’ll go straight to the network in order to be burned.
Risks of EIP 1559
The majority of the people that didn’t agree with the split ended up sticking to the old version of Ethereum, which is now known as Ethereum classic. We will cover the definitions of forks in general (what they are, why they happen and so on). After that, we’ll focus on the Ethereum forks – you’ll find out when they happened, what they changed and what the future holds. Ethereum Metropolis, Classic & EtherZero described in complete Ethereum fork guide. “The Hard Fork is a delicate topic and the way we see it, no decision is the right one.
What Is the London Hard Fork?
Before making financial investment decisions, do consult your financial advisor. As soon as Ethereum Serenity kicks into play, no one knows what will happen to the economy. 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. 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.
What does the community think?
Soft-forks are therefore, backwards-compatible and after the soft fork, still only one blockchain exists as both upgraded and non-upgraded nodes work on the same chain. So it’s more like a software upgrade where you can still read and use older versions of files created by the program. A hard fork essentially creates an entirely new currency as it is a permanent divergence from the previous version of the blockchain. One path will follow the new, upgraded blockchain and the other one follows the old path. The users of that particular blockchain can elect to upgrade and follow one path or not upgrade and stay with the other.
