It will be a trusted system with far fewer scalability issues and a much larger feature set than its primary competitors. Only time will tell if the launch of the upgrade will be the signal of a new blockchain era, but the one certainty is that a new day is dawning for Ethereum – and for the cryptocurrency space as a whole. It will help by splitting up the load created by large amounts of data needed by Layer-2 networks operating on Ethereum. Sharding becomes possible after the Merge and is expected to become available sometime in 2023. This is something a lot like replacing an airplane engine while it’s still flying, an event that, if it goes off without a hitch, will go down in blockchain history. Every twelve seconds, the Beacon Chain will randomly select a group of validators and designate roles.
- Now that The Merge is complete, miners are out and validators are in.
- We may, but are not obligated to, update any outdated, incomplete, or inaccurate information.
- This carrot and stick approach is designed to incentivize participants to contribute to validating and ordering transactions in blocks in accordance with the rules of the protocol.
- Once a block is finalized, reverting that block requires at least 1/3 of all validators to burn their deposits, which is estimated to cost over 3 million ETH.
- To address this, Ethereum 2.0 will begin the use of web assembly language, in a system they’re calling eWASM.
- “At the end of this road map, Ethereum will be a much more scalable system…By the end, Ethereum will be able to process 100,000 transactions per second,” Buterin said.
- Economic penalties for misbehavior in the form of “slashing” make it exponentially more costly for bad actors to attempt attacks as compared to proof of work.
Under PoW, block building and mining (i.e.proposing and confirming a block) were all handled by the same network actor. Because mining requires specialized tools and knowledge, only a small set of mining pool operators ended up being responsible for the vast majority of block construction – making this both opaque and centralized. A newer sharding design, called Danksharding, is gaining traction in the Ethereum community. Danksharding introduces significant simplifications to previous sharding designs and introduces the concept of Proposer/Builder Separation .
Will The Merge Lower The Gas Fees Everyone Complains About?
Ahead of the Merge, many crypto advocates within and outside the Ethereum ecosystem have raised concerns about the network’s ability to evade censorship in light of the U.S. It’s feared that a Proof-of-Stake Ethereum would be easier to censor than a Proof-of-Work network since many big network validators such as Coinbase are based in the U.S. In order to uphold Ethereum’s decentralization, these validators would need to process all transactions assigned to them, even if they do not comply with the Treasury’s sanctions.
People who stake their ETH to provide security to the network receive all the block rewards and transaction fees generated by the network (excluding all fees burned by the network due to EIP-1559). It is shared equally among the pool of stakers – it doesn’t matter if you were in a chosen group of participants, you still get rewards. The landmark update will bring major changes to the Ethereum network, including a 99.95% reduction in energy Ethereum Proof of Stake Model consumption and a 90% cut in ETH issuance. In addition to the transition to Proof-of-Stake, The Merge included multiple upgrades to how the Ethereum network operates, as covered by this blog. Many of these upgrades make pre-chain data more important than ever when navigating a post-Merge world to ensure your users can transact with confidence. In turn, the block proposer will receive a reward for slashing the malicious validator.
While people doubt, Ethereum developers will make the merge proof-of-stake happen. While Proof of Work has been battle-tested for over a decade in Bitcoin and since 2015 in Ethereum, Proof of Stake has less of a track record. Although Proof of Stake has been used in a number of public blockchains without incident, the relatively high complexity of its implementation in Ethereum means there may be as-yet unknown attack vectors or vulnerabilities. After the Merge, this consumption should drop by almost 99.95%, which would make its total energy expenditure below 0.01 terawatt-hours a year.
A vast amount of capital is being allocated toward researching and discovering how fixed block times will impact gas fees. We at Blocknative believe that we will see a new phenomenon, post-Merge, that will affect the entire network and the nature of the gas marketplace. Although EVM is widely used, it remains something of an enigma – even for people with a high degree of programming skill. To address this, Ethereum 2.0 will begin the use of web assembly language, in a system they’re calling eWASM. That would make it possible to execute Ethereum app code right in today’s web browsers, which is a massive improvement over the EVM. Also, it will allow programmers to choose from several languages like Rust, C, and C++ to write code to run on the blockchain.
The total security of any given PoW public blockchain network is measured in hash power, or the total amount of computation devoted to securing the network. Because mining requires specialized equipment and skills, the majority of hash power on Ethereum was previously controlled by a small number of privately operated mining pools. Improved capacity to scale by supporting ‘shard chains.’ Shard chains increase transaction throughput by allowing a network to create multiple blocks simultaneously.
But even though this project sounds like ETH, and somewhat includes Ethereum in its name, it is not correlated with Ethereum, and will have its own token and applications if it succeeds. Developers have conducted as well 10 mainnet “shadow forks” where they ran through the merge using a small number of nodes. This proved helpful since the shadow fork process is minimal enough to not disrupt the mainnet, but useful enough to assess any potential issues prior to the big mainnet merge. As developers continue to prepare for the merge, they’re planning still more shadow forks. Prior to the upcoming merge, testnets Kiln, Ropsten, Sepolia, and, most recently, Goerli all underwent the transition to proof of stake as dress rehearsals for the real event. This is unsurprising since, during the busiest periods on Ethereum, gas fees can reach hundreds of dollars, making the network unviable for many.
Whats Next For Ethereum?
In 2021 and more recently, Ethereum NFTs received fierce criticism in the mainstream world, but the environmental arguments detractors made are all but redundant now that the network uses Proof-of-Stake. If the public gets used to the idea of an energy efficient Ethereum, that will undoubtedly raise questions about Bitcoin and its reliance on Proof-of-Work. Besides the macro picture, crypto has endured a slump for almost a year now, seeing its market capitalization plummet from $3 trillion to around $1 trillion. Even if the Fed turns dovish next week, retail interest in digital assets has taken a hit relative to this time last year, and crypto has few if any catalysts left beyond the Merge.
Namely, critics say proof of stake will make Ethereum more centralized and less secure, and point to the dominance of a few entities holding staked Ether . As data firm Messari has pointed out, Lido Finance controls a whopping 31.2% of all staked Ether on the Beacon Chain, while Coinbase controls 14.7% and Kraken 8.5%. Also on Ethereum’s road map are four other phases happening in parallel that developers are calling the “surge, verge, purge, and splurge”—all of which aim to make Ethereum much faster, safer, and more decentralized. “At the end of this road map, Ethereum will be a much more scalable system…By the end, Ethereum will be able to process 100,000 transactions per second,” Buterin said. In his latest newsletter, Outumuro predicts that because the cryptocurrency will no longer be awarded to miners, the amount of new Ether issued will drop by approximately 87%.
With substantially less energy and less expensive hardware, stakers will not require as much ETH to be incentivized to participate in securing the network. This combined with the ETH being burned since EIP-1559 can make the Ethereum asset deflationary. Despite the clear arguments for a bearish ETH and the broader crypto space today, the Merge is arguably the biggest catalyst for a rally that Ethereum has ever seen. According to ultrasound.money data, ETH’s supply will peak at 120.5 million and decrease by about 1 million coins a year. Starting it all, an upgrade called Bellatrix—named after a star and not the villain from Harry Potter—happened on Sept. 6 and set things into motion. Next, the network will need to reach a final Terminal Total Difficulty value, which represents the potential difficulty level for mining, once the Bellatrix upgrade is complete.
Pos Is More Efficient, Using ~99% Less Energy Than Pow
Instead of settling all operations on one single blockchain, these shard chains spread operations across 64 new chains. Sharding is planned to begin in 2023 and should enable giant leaps in scalability for the network. A “beacon chain” was established to store the registry of validators and run in parallel to Ethereum mainnet, but during the Beacon Chain phase, Ethereum continues to rely on the Proof-of-Work consensus mechanism. Ethereum 2.0, sometimes called Eth2 or Serenity, is an upgrade to the Ethereum blockchain. It aims to increase the speed, efficiency, and scalability of the Ethereum network while not compromising its security or decentralization.
Likewise, a validator could be slashed as a result of completely accidental actions including not having slashing protection up to date on failover servers or using duplicate keys. There was an immense amount of anticipation and speculation regarding the changing dynamics that would come with Ethereum’s Merge. Years of planning went into ensuring that most network participants would notice minimal changes on Day 1. But there are still some misconceptions around exactly what The Merge accomplished. ConsenSys R&D Launches an Updated and Expanded zk-EVM VersionUsing our design, developers can deploy any smart contract, use any tool, and develop exactly as if they were building on L1.
This is because being a whistleblower is intended to be an altruistic action and not meant to be profitable. For staking more coins, all users have a higher probability to validate transactions in the network and earn more coins or rewards. In the proof-of-work, miners must complete complicated puzzles to validate financial transactions on the blockchain. The blockchain will see its first divisions of processing, enabling parallel transaction validation for the first time.
That allows the whole blockchain to make use of parallel processing, which could increase overall capacity several times over. Between this added technique and the switch to proof-of-stake, the new Ethereum blockchain should be far faster and more efficient than its predecessor. Sharding is the process of splitting one blockchain into multiple blockchains known as shards. Because validation of the blocks on each shard is done independently, when taken as a whole, the network is able to process a greater number of transactions.

Validators propose new blocks, submit attestations , and monitor for any slashable offenses . Because the Execution Layer relies on current Ethereum clients, maintaining it allowed for a smoother transition for dapp developers during the network’s move to proof-of-stake as no migration was necessary on their end. The Proof of Work consensus mechanism is not sustainable and not scalable long-term.
The Future For Developers After The Merge
In one fell swoop, eWASM will increase the number of potential programmers for the ecosystem, because it will open the doors to users with no need to learn a native Ethereum-only language. One of the features that have made Ethereum such a viable https://xcritical.com/ platform and a worthy challenger to Bitcoin’s dominance is its implementation of what’s known as the Ethereum Virtual Machine . The EVM is an execution environment that runs on all network nodes that facilitates the use of smart contracts.
It allows validators to sell blockspace to so-called block builders and outsource block production to maximize their reward—effectively subcontracting some of their validating duties. But while the merge is bad news for miners, the vast majority of the Ethereum community and beyond see the end of mining as a good thing—helping both the planet and Ethereum’s reputation. “The switch from proof of work to proof of stake reduce overall energy consumption of Ethereum by 99.9% or more,” Ethereum core developer Preston Van Loon told Fortune. Accurate gas fee estimation will help your users make it on-chain without anxiety.

To Ethereum core developer Tim Beiko, the biggest misconception about the merge is that you need 32 Ether to run a node, he told Fortune. “Thirty-two Ether is only needed to run a validator,” as mentioned earlier. Buterin himself doesn’t see a 51% attack as “fatal,” and the Ethereum community has likewise downplayed the concern, reminding others of the ability to slash a validator’s stake, among other things.
The one notable exception is Ethereum, which has long been the lone, large-scale competitor to Bitcoin. For its part, though more advanced than Bitcoin, Ethereum also suffers from some issues that it would need to overcome to achieve market dominance. That’s exactly what the developers behind Ethereum hope to accomplish with their upcoming upgrade of the underlying blockchain, which they’re calling Ethereum 2.0.
The Merge also sets up Ethereum for bigger upgrades in the future that will increase its transaction speeds up to more than 100,000 per second, which will make it faster and cheaper to use. This increased scalability will open up Ethereum for a whole new wave of applications and opportunities. The merge does set the stage for sharding, which will increase block space and thereby decrease gas fees.
The reason for this misconception is that at one point “The Merge” was going to include sharding but this has been separated into its own upgrade. In proof of stake all the nodes are playing a coordination game instead of a competitive one. This unlocks new ways to scale with the building blocks in place for sharding. With the Beacon Chain coordinating between all the validators, it is a small adjustment to start coordinating consensus on multiple shards of the network. Without the need for specialized hardware, anyone can become a staker. The more people that participate in security, the more robust a chain becomes.
This includes new changes to block finality , new MEV-related transactional risks, and new economic incentives that could result in your wallet ultimately paying you to use it. In another bid to improve Ethereum’s efficiency and ability to scale, the coming changes will also introduce a processing technique known as sharding. In the current blockchain version, all data that is added to the chain has to undergo verification by all participating nodes. That means that the processing speed of the entire system is limited by the speed of its slowest participant. It creates a bottleneck that increases transaction costs and decreases throughput. One of the reasons that early blockchain implementations suffered from performance issues was the fact that they rely on a processing-power-intensive process known as proof of work to validate and record transactions.
