***TLDR — “***The Merge” is the most significant upgrade in Ethereum’s history. Ethereum will transition from proof-of-work to proof-of-stake consensus. This upgrade will drastically reduce Ethereum’s carbon footprint, enable scalability solutions like sharding, and change the ETH issuance rate. Ethereum users do not need to do anything for the merge.

It’s not an exaggeration to say this is the biggest upgrade in Ethereum’s history. Frankly, it’s the biggest upgrade in any blockchain’s history when you consider no other public network at the same scale has changed its consensus mechanism live.

Before diving into the deep end, it’s important you know that you do not need to do anything to prepare for the merge. There will be no new token to claim, there is no sign-up process, and you will not have to upgrade anything or use a new site for the dapps you use today. Be cautious of anyone suggesting otherwise because they are probably trying to scam you. See Ethereum’s official site for more details on this.

Now to dive right in, the upcoming merge will transition the network from a proof-of-work consensus mechanism to a proof-of-stake consensus mechanism. This has a cascading set of ramifications that will impact Ethereum’s ETH issuance rate, its carbon footprint, and how the chain operates at large.

Moving to proof-of-stake was part of Ethereum’s original roadmap and research started before the network first launched. The transition has been separated into two phases to reduce the risk of failure.

Phase 1: Beacon Chain Deployment

Phase 2: The Merge

The Beacon chain was launched on December 1, 2020 in preparation for the merge and has been running separately since then. The Beacon chain is the network that is currently running proof-of-stake consensus. It’s pre-merge iteration doesn’t handle mainnet transactions, but after the merge it will and the previous proof-of-work chain will be shut off.

While this is a major change for the network, Ethereum users won’t have to do anything to prepare and may not even notice a difference. All the transaction history from the current network will exist on the the proof-of-stake version. This means all your bags will be safe and available after the merge, which has a soft deadline of September 15, 2022 at the time of writing.

The motivations for the upgrade can be broken down into three key reasons:

• Network efficiency & scalability

• Reduce ETH issuance

• More security & consensus participation

The foremost reason is to make Ethereum more energy efficient and scalable. Switching to proof-of-stake will reduce the energy consumption of the network by 99.95%, which removes any concerns about the ecological impact Ethereum has moving forward. This is because the hardware and electricity used in proof-of-work will not be necessary in proof-of-stake.

The merge also lays important ground work to implement sharding, a key component to make Ethereum significantly more scalable.

The ultra sound money thesis will also be realized as a result of the upgrade because ETH the asset will no longer be inflationary in nature. The merge achieves this by drastically decreasing the amount of new ETH created per block while maintaining the existing burn rate, which is the amount of ETH removed from circulation.

Ethereum pre-merge runs on proof-of-work, which rewards miners for every valid block added to the chain and creates roughly 13,000 new ETH per day. Post-merge, Ethereum will run on proof-of-stake and reward validators for every valid block, creating roughly 1,600 ETH per day.

This itself significantly reduces issuance but in combination with Ethereum’s burn rate inflation goes to zero or less. Since August 2021, every transaction on Ethereum burns a percentage of ETH used to cover gas costs. About 1,600 ETH is burned at an average gas price of at least 16 gwei. Even more is burned at higher costs, which happens when the network has a lot of activity. This results in more ETH being burned than created as it gets more usage, making it deflationary instead of inflationary.

Finally, migrating to a proof-of-stake system will allow more people to participate in Ethereum’s consensus mechanism than proof-of-work, which makes the network more decentralized and secure. This final point has some caveats but at the time of writing it’s more accessible to become a validator than a miner on Ethereum.

You need to have 32 ETH staked in order to become a validator and earn ETH as a reward for successfully validating blocks. However, this is still much cheaper and easier than profitably running your own mining hardware. The competition and high cost in mining means it’s dominated by institutions and sophisticated miner groups.

To be a miner, you need

• optimal hardware to be competitive, often multiple mining rigs

• space to store them

• the electricity to power them

There’s also the cost of buying more or newer, faster rigs if the hashrate goes up to stay competitive and profitable.

This can easily costs thousands of dollars in recurring expenses. Miners also have to be aware of drastic price movement because they make their money in ETH, so it may suddenly be unprofitable to keep their rigs running if the price drops.

Becoming a validator is still a high cost though, 32 ETH at the time of writing is worth about $49,410. But this is a one time cost unlike mining and does not require any specialized equipment. Additionally, services like Rocket Pool, a decentralized staking protocol, allow you to operate a node and earn rewards with only 16 ETH.

You can even earn staking rewards without putting in the majority share to run a node and just make up some of the difference. It’s reasonable to expect more services like this with more competitive rates or greater rewards will become available as Ethereum gets more usage, lowering the amount to participate even more for new stakers.

That’s a high-level overview of Ethereum’s upcoming merge. The merge is Ethereum’s long-awaited transition from a proof-of-work consensus mechanism to a proof-of-stake consensus mechanism.

Miners will be replaced by validators in this new paradigm, which will reduce Ethereum’s energy consumption by 99.95% because electricity and hardware will no longer be required for the chain to function.

The transition will allow Ethereum to become more scalable with later upgrades like sharding. And ETH issuance will be reduced so much that the rate of inflation will be zero or even negative, making it deflationary in nature instead.

Participation in network security will also be more accessible because you will no longer need hardware, storage space, and recurring overhead costs like electricity to participate.

As a result, network security will arguably be more decentralized and secure because participation simply requires you to stake ETH making the barrier to entry much lower. While this is still a high cost, it’s less than maintaining profitable mining rigs and this barrier will likely continue to lower as more decentralized staking services arise.

Finally, Ethereum will behave the same as it did before the merge, so you won’t need to do anything to prepare for it unless you’re running a node or staking. You can continue to ape into the next big NFT project or be the DeFi degen you’ve been for the past year without skipping a beat.

When is the Ethereum Merge?

The Ethereum merge date is set for September 15, 2022. This is subject to change if there are any unexpected complications.

Will the Ethereum merge reduce gas fees?

No. Gas fees are a result of network usage. The more demand to use the network, the higher the gas fees. The merge doesn’t directly affect this in any meaningful way.

Will Ethereum transactions be faster after the merge?

No. Some slight changes still exist, but transaction speed will mostly remain the same until scaling solutions like sharding are implemented.

Will there be a token drop after the merge?

No. There will be no token drops or claims for the merge.

PSA: Be aware of scams that will try to convince you otherwise!

Can I withdraw staked ETH after the merge?

No. Staking withdrawals will not be included as part of the merge in order to simplify the transition. Staking withdrawals will be enabled in the Shanghai upgrade, which is slated to come 6–12 months following the merge.

Will stakers all exit when withdrawals are enabled?

No. There are rate limits set for validators who exit to prevent this for security reasons.

Is Ethereum and Ethereum 2.0 the same?

Yes and no.

Yes because for a typical Ethereum user nothing will change and Ethereum will behave the exact same.

No because the consensus mechanism under the hood is completely different and introduces the option for you to stake ETH to participate in network security and earn ETH.

Additionally, the term “Ethereum 2.0” will no longer be used and the network will continue to be known as “Ethereum”, so it will feel like the same Ethereum you’ve been using for the past year if you are not staking.

What happens to ETH when ETH2 comes out?

There will be no “ETH2”. After the merge, your ETH balances will remain the same. There will be no other version of ETH and the phrases “ETH2” & “Ethereum 2.0” will no longer be used to avoid confusion.

If you have been staking and earning ETH on the Beacon chain, your staked ETH and rewards from newly issued ETH will continue to be locked until the Shanghai upgrade. You will, however, earn ETH used to pay for transactions. This is because the tip that used to go to miners will instead go to validators after the merge.

Will the Ethereum network go down for the merge?

No. Ethereum is expected to have zero downtime during this transition.

Will Ethereum go up after the Merge?

Ethereum will go up and down after the merge and not necessarily in that order, just like it always has.
