The Ethereum Merge marks one of the most significant upgrades in blockchain history. As Ethereum transitions from a Proof-of-Work (PoW) to a Proof-of-Stake (PoS) consensus mechanism, users, stakers, and developers alike are seeking clarity on what this change means for the network, staking rewards, tokenomics, and long-term sustainability.
Below is a comprehensive guide addressing the most frequently asked questions about the Merge—designed to help you understand its implications, prepare accordingly, and stay informed about the future of Ethereum.
What Is the Merge?
The Merge refers to the pivotal moment when Ethereum fully transitions from energy-intensive Proof-of-Work (PoW) mining to an environmentally sustainable Proof-of-Stake (PoS) validation system. This upgrade integrates the existing Ethereum mainnet with the Beacon Chain, which has been running parallel since December 2020 as the PoS backbone of the network.
This shift eliminates mining as a method for securing the network and instead relies on validators who stake ETH to propose and attest to new blocks. The transition is expected to reduce Ethereum’s energy consumption by over 99.95%, making it one of the greenest major blockchains in operation.

When Will the Merge Happen?
The Merge was scheduled to occur around September 15, 2022, triggered by reaching a specific Total Terminal Difficulty (TTD) threshold of 58,750,000,000,000,000,000,000. While exact timing depends on network conditions, all major testnets successfully executed the transition prior to the mainnet upgrade.
Although the original date has passed, the technical details remain relevant for understanding Ethereum’s evolution. You can track historical progress and network metrics via public tools designed to monitor consensus changes.
Is It Safe to Stake During the Merge?
Yes, staking during the Merge is safe. For users leveraging liquid staking solutions like Lido, there is no disruption to service or reward accrual. Stakers continue earning daily returns on their positions throughout the transition.
While the network remains fully operational during the Merge, there may be brief periods of reduced participation or minor instability immediately surrounding the event. These are expected to be short-lived and do not pose significant risk to staked assets.
Validators who are actively participating will see uninterrupted operations post-upgrade, with enhanced economic incentives under PoS.
What Happens After the Merge?
After the Merge, Ethereum operates entirely under Proof-of-Stake. Key outcomes include:
- End of mining: No more miners; blocks are produced exclusively by stakers.
- Dramatic energy savings: Estimated reduction of 99.95% in electricity usage.
- Improved security model: Economic finality and slashing mechanisms deter malicious behavior.
- Continuity of decentralized applications (dApps): All smart contracts and user balances remain unchanged.
Importantly, while the consensus mechanism changes, core user experiences—such as sending transactions or interacting with DeFi platforms—remain unaffected.
How Does the Merge Affect stETH?
stETH, or staked ETH, represents a liquid tokenized form of ETH staked through services like Lido. The Merge does not unlock staked ETH—withdrawals were not enabled until a later upgrade (Shanghai). However, stETH continues to function normally:
- Accrues staking rewards in real time
- Remains tradable on decentralized exchanges like Curve and Uniswap
- Maintains interoperability across DeFi protocols
In essence, stETH becomes even more valuable post-Merge as it provides liquidity and composability within a fully staked ecosystem.
Will My Staking Rewards Increase After the Merge?
Yes—staking rewards are expected to rise slightly after the Merge due to additional revenue streams now available to validators:
- Priority fees (tips paid by users for faster transaction inclusion)
- Maximal Extractable Value (MEV) rewards from efficient block ordering
Liquid staking providers like Lido capture and re-stake these earnings, increasing the overall yield for stakers. This leads to a higher effective APR on staked ETH compared to pre-Merge levels.

Can I Withdraw My Staked ETH After the Merge?
No. Direct withdrawals of staked ETH were not enabled at the time of the Merge. Full unstaking functionality was introduced later via the Shanghai upgrade, which launched in April 2023.
Until that point, users could only access liquidity by trading stETH on secondary markets. Now that withdrawals are live, users can request withdrawals directly through the consensus layer or via liquid staking platforms that support them.
What Should ETH Holders Do?
ETH holders need to take no action. The Merge does not affect token balances, private keys, or wallet addresses. Your ETH remains secure and fully functional across wallets and dApps.
However, if you're involved in lending or borrowing ETH (e.g., through Aave or MakerDAO), be aware that volatility around major upgrades can temporarily impact interest rates or collateral ratios.
What Should Stakers Do?
Stakers also require no intervention. Whether you're using solo staking or a liquid staking service:
- Rewards continue accruing daily
- stETH remains exchangeable
- No migration or manual upgrade is needed
If you're using leveraged staking strategies in DeFi, exercise caution during high-volatility periods surrounding protocol upgrades.
How Does the Merge Impact Lido?
Lido remains a key player in Ethereum’s PoS ecosystem. As a leading liquid staking protocol, Lido enhances accessibility by allowing users to stake any amount of ETH without managing validator infrastructure.
Post-Merge benefits for Lido include:
- Increased demand for liquid staking derivatives
- Higher APR due to inclusion of MEV and priority fees
- Continued integration across Layer 2s and DeFi platforms
Lido is built specifically for PoS Ethereum and has no plans to support alternative forks such as ETHPoW.
Will Lido Support ETHPoW?
No. Lido is designed exclusively for Proof-of-Stake Ethereum. There are no governance proposals—and no intention—to distribute tokens from any potential PoW fork (e.g., ETHPoW) to stETH holders.
Users should be cautious of misleading claims or third-party airdrops associated with non-official chains.
How Does the Merge Affect ETH Tokenomics?
The Merge significantly improves Ethereum’s economic model when combined with EIP-1559, which introduced fee burning:
- Lower issuance rate: PoS requires far less new ETH issuance than PoW
- Fee burning: Base transaction fees are destroyed, removing ETH from circulation
- Potential deflationary pressure: Under high usage, more ETH may be burned than issued
This dynamic creates conditions where ETH could become net deflationary, enhancing its scarcity and long-term value proposition—especially as adoption grows.
What Are the Risks Post-Merge?
While PoS offers efficiency and sustainability, it introduces new considerations:
- Centralization concerns: Large staking pools may accumulate disproportionate influence
- Slashing risks: Validators can lose funds for malicious or negligent behavior
- New attack vectors: Long-range attacks or stake-bribery scenarios require ongoing monitoring
However, Ethereum’s design includes robust countermeasures such as slashing penalties, minimum slashing epochs, and decentralization incentives to mitigate these risks.
Does the Merge Improve Scalability or Lower Gas Fees?
No. The Merge itself does not reduce gas fees or increase transaction throughput. Users should expect similar fee levels post-transition.
Scalability improvements come from future upgrades like:
- Proto-danksharding
- Danksharding
- Rollups and Layer 2 solutions
These innovations will build on top of the PoS foundation laid by the Merge.
Does Ethereum Become Faster After the Merge?
Block production becomes slightly more consistent—every 12 seconds under PoS versus an average of 13–14 seconds under PoW—but this minor improvement does not translate into noticeable performance gains for end users.
True speed and scalability enhancements will come from Layer 2 rollups and sharding upgrades down the line.
How Much Does the Merge Reduce Energy Consumption?
According to estimates from the Ethereum Foundation, transitioning to PoS reduces energy consumption by approximately 99.95%. This makes Ethereum vastly more sustainable than PoW blockchains like Bitcoin.
This dramatic reduction positions Ethereum as an environmentally responsible platform capable of supporting global-scale applications without ecological harm.
