Legal Experts Examine The Dao Attack And Ethereum Fork

Ethereum Hard Forks

This sort of undesirable situation which occurs when a device or system attempts to perform two or more operations at the same time is known as a race condition. In hindsight, this could have been prevented by structuring the contract to update first and then issue the reward, noted Antonopoulos. The Abu Dhabi National Oil Company announced on December 9 its collaboration with US tech giant IBM. According to the ADNOC’s press release, blockchain “will reduce the time it takes to execute transactions between ADNOC’s operating companies and significantly increase operational efficiencies across its full value chain”. Additionally, the company declares this technology will improve the reliability of production data providing better transparency.

  • We then propose an implementable, ethical framework for blockchain protocol designers to decide which aspects of their protocol are immutable and which are not.
  • One of the most immediate outcomes of this otherwise impressive upgrade will be an expected “soar” throughout 2019.
  • Enforcement can be voluntary if the Regulation Condition is designed to focus on financial incentives.
  • The ether that would otherwise go to the miner is now “burned”, permanently destroying some of the digital currency that would otherwise be put back into circulation.
  • Bootstrapping a new supply distribution would require years of high inflation, making the asset unattractive to hold.
  • We mention this only for the sake of completeness because in many other blockchains, upgrades face an inherent uphill battle.

But if miners did implement a MASF, it would be an unprecedented and self-destructive attack on Ethereum and hence their own investment. But on further reflection, this approach is also loaded with problems, and the issue is around supply distribution. Having established this basic relationship between miners and users, we will apply the framework to various scenarios of how the EIP-1559 activation could play out. To understand the power dynamic in Ethereum, it is important to understand that all three sources of revenue stem from users and the applications and businesses that serve them. Then, earlier today, Popular cryptocurrency analyst Michaël van de Poppe expressed his bullishness in ETH by saying that he believe that ETH will eventually flip BTC (i.e. its market cap will eventually exceed that of BTC).

Despite the London upgrade being hailed as a major shift for the Ehtereum network, it is not the last fundamental change for the blockchain in the diary. Burning some Ethereum as part of every transaction could also make the crypto more effective as a wealth storage asset, which some believe it could encourage more institutional investment in Ethereum in the long term. The EIP-1559 upgrade aims to remedy this by introducing a ‘base fee’ that is set automatically by a user’s crypto wallet, while also offering the option to ‘tip’ miners to speed up the transaction. Suppose that a group of coin users announces that its proposed change meets the Utility-Maximization and Generalization Conditions, and the group discloses its reasoning processes for the two conditions, which meets the Publicity Condition. Imagine that a different group believes that the proposed change does not meet the Utility-Maximization condition or the Generalization Condition.

In the first EIP rolled out, the guidelines for the following EIPs were set. According to EIP-1, each upgrade must bring details on its technical specifications and its rationale. CYBAVO customers don’t fret- as usual you won’t need to take any steps to upgrade to the latest Ethereum protocol, as it will all be done by our technical team. The difficulty bomb is a mechanism that would prepare network validators to switch from the current proof-of-work to a proof-of-stake consensus model in anticipation of the shift towards Ethereum 2.0. Several exchanges, including Binance, have announced a short-term pause on the buying and selling of ethereum due to the fork. If this happens, the next key level to watch will be the resistance at $60.

The difficulty time bomb is the concept that explains the difficulty behind ether’s mining algorithms. The difficulty bomb means puzzles get more complicated over time, which in turn make it much harder for miners to solve them. So as more miners enter, both the computing power and energy required to compute transactions increase, but the rewards fall, making mining economically unviable. The final hard fork release date follows the successful implementation of the Ropsten and Goerli testnets, important steps in the roadmap to implement Ethereum 2.0. Testnets are the name given to the process of making any changes to Ethereum’s network before a project goes live.

Is MetaMask secure?

Metamask, supported by leading web browsers, is a secure, industry-standard wallet for interaction with Ethereum contracts. MetaMask is trusted by more than a million users worldwide, making one of the most popular Ethereum wallets.

The only limitation to these hard forks is whether there would be a consensus among network users to adopt such changes. The London hard fork went live on 4 August 2021, featuring five Ethereum Improvement Proposal including the highly anticipated EIP-1559. A key element that the fork aims to fix is transaction fees, which have been so high on recent occasions that the network has become largely unusable. With EIP-1559, there is now a base fee added to every transaction, giving users a better idea of what they will pay and, hopefully, lowering overall fees in the long term. However, the blockchain protocol also admits “hard forks,” where network developers introduce software upgrades to the protocol. Essentially every aspect of a specific blockchain protocol may be changed through a software upgrade.

How Does It Affect The Price Of Ethereum?

Upgrades to cryptocurrency platforms are called forks because they’re similar to a fork in the road, where a single chain of blocks gets separated into two chains. Currently, network users need to bid on each other for miners to handle transactions. This means that when the network is busy, the charges are much higher than when it is quiet. The goal of EIP-1559 is to allow users to predict Ethereum transaction fees. A major Ethereum network upgrade is underway and many investors are very excited.

However, this proposal is also likely to deal a heavy blow to miners, which is why EIP-3554 will also be implemented to help ease the increasing mining difficulty. Ethereum’s current gas fee model, which lets users bid on who gets to be added to the next block first, will be replaced by a new model that implements a base fee that is burned instead of being used to pay miners. Users will now pay a base fee, algorithmically determined by network use, but could pay miners a ‘tip’ to have it transacted faster. This change means the fee will now be more stable, with users able to wait for a potentially lower price at a later time. Currently, when a user makes a transaction on the Ethereum network, they pay a fee, known as a ‘gas’ fee, to the Ethereum miner that validates the transaction.

While not getting the same attention as EIP-1559, EIP-3554 is still one of the EIPs in the London fork, and its importance cannot be underestimated. This code change paves the way for ethereum 2.0, an upgrade and total overhaul of the system, which has been years in the making. Hougan argues that because miners are organically linked to the total value of ethereum, the hope is that they will eventually make up for these losses if the price of ethereum rises thanks to these protocol changes. Some have argued that the EIP-1559 upgrade will create some sort of deflationary pressure on ethereum as less supply could lead to a price hike.

That’s “unlike, for example, the meeting, where slight nuances with regards to language used may have a more pronounced impact on reaction by different asset classes,” Vinokourov said. It will take a while, possibly even weeks, to see any real impact from the upgrade. Ether prices also rose by 9,000% in 2017, and made only modest gains thereafter. Also as Marie Tatibouet, chief marketing officer of cryptocurrency exchange Gate points out on, miners can still accept tips, which may cause a “fees war”. The London protocol update introduces five Ethereum Improvement Proposals . Many bitcoin holders cite bitcoin’s ability to stand up against inflation as a key reason to buy it.

And the move to proof-of-stake also means shifting responsibilities to validators, and expensive equipment that miners own will serve no purpose. The long awaited now Constantinople upgrade package will be released atblock number 7,080,000, which has been achieved already.The countdown has stopped and the upgrade is scheduled to go live on Thursday 17. Constantinople will provide several key upgrades to the Ethereum network addressing performance, cost efficiency, and further preparation for an eventual switch to proof of stake consensus. FiveEthereum Improvement Proposals in total will be implemented during the upgrade. EIP-1559 has overwhelming community support and is technically ready to be included in the hard fork after Berlin, pending the usual core developer evaluation process.

Ethereum Hard Forks

If you are the only person who can use X, will your using X increase the total amount of utility of all involved parties including people outside the community? If however this innovation is a way to simply redistribute the financial gains from current mining without reducing the energy costs—as in many arms races—then the innovation would fail the utility test. With a plurality of mining power, a single market participant would threaten the security and validity of the Ethereum blockchain. In response, many Ethereum users (and GPU-dependent miners) proposed adopting a change in the Ethereum network protocol that would render the rumored ASIC miners obsolete.


This comments come as the second largest cryptocurrency has secured an impressive rally over the last month and it is about the make important changes to its network. The technical oversight exploited in the DAO code was a function to issue rewards cryptocurrency in ether when someone created a split proposal. A loop was instantiated whereby the child DAO was continually rewarded by repeated calls. This exploited weakness prevented the code ever reaching the point where it could update the balance.

“It is expected that most users will not have to manually adjust gas fees, even in periods of high network activity. For most users the base fee will be estimated by their wallet and a small priority fee, which compensates miners taking on orphan risk (e.g. 1 nanoeth), will be automatically cryptocurrency for beginners set. Users can also manually set the transaction max fee to bound their total costs. If implemented, miners will no longer receive transaction fees as they will go to the network to be burned. Miners are afraid that they are going to lose a critical source of revenue.

If the miner solves the cryptographic puzzle first, then the miner broadcasts the new block across the Ethereum network and is rewarded with newly minted Ether. Someone claiming to be the attacker of the DAO has added insult to injury by stating that they have taken legal advice and that they are legally entitled to the rewards under the terms of the contract i.e. its code. Miners can already form such a cartel today to e.g. drive up fees by restricting the gas limit, charge higher fees from larger transactions, or set a price floor. All of these strategies seem more profitable at first, but there is good reason miners don’t attempt to implement them. Imagine that instead of 5%, 60% of miners would agree to implement this strategy. The outcome would be the same, since for every half-full block the 60% cartel mines, the other 40% would get to mine full blocks, and get all that extra revenue from congestion fees and MEV, and basefee would still increase over time.

While the Antminer chip requires roughly the same energy consumption as typical GPU-based setups , its speed allows it to more efficiently mine blocks of Ethereum than standard, GPU-based setups3. Miners will only receive the tip, not the base fee – that will be destroyed, or “burned”, and this is what is getting investors so excited. The upgrade is technically called Ethereum Improvement Protocol 1559, or EIP-1559, but has also been dubbed the “London hard fork”. The cryptocurrency market has begun another week with losses, but the scale of them could be described as moderate compared to previous days. Bitcoin has lost nearly a 1%, Ripple has declined around 2.5%, and Ethereum has experienced over a 1.5% drop.

This can be compared to past Bitcoin halvings – where the block reward to miners is cut in half – and has boosted its price previously. These fees also won’t be going to the miners anymore, but to the network itself, meaning they’re effectively burnt and removed from circulation. As well as being used as a cryptocurrency, developers can also build applications and run smart contracts on Ethereum. He said he can’t see a definite trend in the short term, but a relative value trade could be implemented between ether and bitcoin.

As a consequence, remaining Defi apps on the fork chain that rely on collateral would also unwind, for example the collateral-backed stablecoin DAI or any form of AMM pool. In short, everything other than ETH, including important off-chain infrastructure like oracles, liquidation bots, etc. would blow up and it would create Ethereum Hard Forks a huge mess on the fork chain. Ultimately, the power dynamic between users and miners can be explained with replaceability. It is near impossible for miners to replace the current Ethereum users as their main source of revenue. But it is very possible for users to replace some or even most of the current Ethereum miners.

Scenario 1: Miners Maintain The Old Chain Without Eip

We expect no chain splitting to occur as a result of the Constantinople hard fork, which means that no new cryptocurrency will emerge. Ethereum developers plan to completely overhaul the coin network next year, which is expected to have a further impact on its price. Some have used last years Bitcoin halving as a means of comparison to the Ethereum upgrade, when Bitcoin’s block reward was halved from 12.5 to 6.25 bitcoin in May 2020 and resulted in a supply shock that sent the price rocketing.

Will Ethereum go up in 2021?

Ether has already climbed more than 400% in 2021, and some experts say it could be headed toward $4,000 as it benefits from increased transactions and a spike in NFT purchases on the Ethereum blockchain.

Ether prices rose in digital-asset markets on Thursday after the Ethereum blockchain’s “London hard fork” went live, and cryptocurrency analysts are now weighing in on the impact of the network upgrade. Ethereum is the world’s second-biggest cryptocurrency and is the largest blockchain for supporting a multitude of decentralised financial applications. The world’s second-biggest cryptocurrency is getting a revamp that should increase the speed of transactions on the Ethereum blockchain and lower their cost. The new update promises to lead Ethereum away from the energy-intensive ‘proof of work’ mechanism for validating transactions and to the more environmentally friendly ‘proof of stake’. We illustrate the consequences of permitting any changes to a blockchain protocol by examining proposed changes to the Ethereum protocol that arose in April 2018. Other cases of Ethereum hard forks have occurred since 2015, such as Constantinople, and Byzantium.

They would only mine blocks that are half-full or smaller, even if demand far exceeds that level. Meanwhile, the other 95% of hashpower would mine larger blocks, make more revenue from fees, and the basefee would increase anyway. The 5% mining pool quickly would realize it is bleeding money and give up or lose all of its hashpower. This shows that self-interested miners want to include as many transactions as possible, as long as there is competition between them. This opportunity cost is no joke, since—as we previously established—in order to pay miners any revenue, a blockchain first needs to create value for users for there to be a valuable block subsidy, congestion fees and MEV.

If so, then the miner has successfully mined the block of Ethereum; if not, the miner must repeat the process with a new nonce. Ethereum’s mining process is in many ways similar to Bitcoin’s proof-of-work protocol. Miners listen for broadcasts of transactions that should be added to the Ethereum blockchain. Miners aggregate these broadcasts into a block of transactions and then compete to solve a complicated cryptographic puzzle.
