The Ethereum network’s long-anticipated transition to Proof-of-Stake (PoS), commonly known as "The Merge," has sparked widespread discussion, speculation, and confusion. With multiple dates circulating—such as September 6 and September 15—many are left wondering: When exactly will the PoS Merge happen? And more importantly, what does it actually mean for ETH holders, validators, and the broader ecosystem?
To stay updated in real time, you can monitor the progress via merge tracking tools like merge countdown platforms. But beyond dates and dashboards, understanding the technical phases, dispelling myths, and grasping the real-world implications of this upgrade is essential.
Let’s break it down step by step.
🔍 How The Merge Affects Ethereum’s Supply
One of the most significant economic shifts brought by The Merge is its impact on ETH issuance.
Before The Merge:
- Daily ETH issuance: ~13,000 ETH
- Annual inflation rate: ~4.62%
After The Merge:
- Daily ETH issuance drops to ~1,600 ETH
- Annual inflation rate falls to approximately 0.5%
- Supply reduction of nearly 90%
This dramatic cut comes from eliminating energy-intensive mining rewards. However, one thing remains unchanged: EIP-1559’s fee-burning mechanism. Transaction fees continue to be burned based on network activity, meaning high usage = more ETH burned. In periods of strong demand, Ethereum could even become deflationary.

❌ Debunking 8 Common Misconceptions About The Merge
Despite extensive documentation, many misunderstandings persist. Let’s clarify them with facts.
Misconception 1: “After The Merge, I Can Immediately Withdraw My Staked ETH”
Reality: No. The Merge only transitions consensus from PoW to PoS. Withdrawals are not enabled until the Shanghai upgrade, which follows months later. Until then, staked ETH remains locked.
Misconception 2: “Validators Won’t Receive Any Usable Rewards Until Withdrawals Are Live”
Reality: False. While principal staking balances can’t be withdrawn yet, MEV (Maximal Extractable Value) and transaction fee rewards are already claimable post-Merge. These rewards go directly to the validator’s linked withdrawal address and are immediately spendable.
Misconception 3: “Once Withdrawals Launch, I Can Instantly Exit My Stake”
Reality: Exit speeds are rate-limited for security reasons. Validators must queue for exit processing—only a limited number can withdraw per epoch (~6 validators per slot). This prevents mass exodus scenarios that could destabilize the network.
Misconception 4: “APY Will Triple to 12% Overnight After The Merge”
Reality: While staking rewards increase due to inclusion of gas fees and MEV, estimates suggest post-Merge APR will be around 7%, not 12%. This depends heavily on network utilization and total staked supply.
Misconception 5: “Gas Fees Will Drop Significantly After The Merge”
Reality: The Merge changes consensus, not scalability. It doesn’t increase block size or throughput. Therefore, gas fees remain largely unaffected. Scalability improvements come later via rollups and Ethereum’s Surge roadmap.
Misconception 6: “Transaction Speed Will Improve Dramatically”
Reality: Block times become more consistent—averaging exactly 12 seconds—but this doesn’t equate to faster transactions for users. Finality improves slightly, but user experience stays similar to pre-Merge conditions.
Misconception 7: “You Need 32 ETH to Run an Ethereum Node”
Reality: Anyone can run a full node without staking. The 32 ETH requirement applies only to becoming a validator who proposes and attests to blocks. Regular nodes help with decentralization and data availability but don’t earn staking rewards.
Misconception 8: “The Network Will Go Down During The Merge”
Reality: The Merge is designed as a seamless, non-disruptive upgrade. There is no scheduled downtime. Users and dApps continue operating normally throughout the transition.
🧩 What Exactly Is The Merge?
Currently, Ethereum operates two parallel chains:
- Execution Layer (Eth1): The current mainnet handling transactions and smart contracts under Proof-of-Work (PoW).
- Consensus Layer (Eth2 / Beacon Chain): Running since December 2020, this PoS chain manages validator coordination and finality.
The Merge unifies these layers:
Post-Merge Ethereum = Execution Layer (Eth1) + Consensus Layer (Eth2)
- Execution Layer: Handles all user activity—transactions, contract executions, account balances.
- Consensus Layer: Validates and finalizes blocks using staked ETH instead of computational work.
This integration marks the end of energy-intensive mining and ushers in a more sustainable, secure, and economically efficient blockchain.
⏳ Three Critical Stages of The Merge
The transition unfolds in three coordinated phases:
Step 1: Bellatrix Upgrade (Consensus Layer Preparation)
- Time: September 6, 2025, at 19:34 UTC (Epoch 144896)
- Purpose: Prepares the Beacon Chain for execution payload integration.
- Key Change: Instructs consensus clients to start accepting execution-layer data after Total Terminal Difficulty (TTD) is reached.
- Note: This step has no immediate effect on the PoW mainnet.

Step 2: Reaching Total Terminal Difficulty (TTD)
- Estimated Time: Around September 15, 2025
- TTD Value: 58,750,000,000,000,000,000,000
- What Is TTD? A cumulative measure of mining difficulty used as a deterministic trigger point.
- Why Use TTD? To avoid predictable timing attacks or forks. Since hash power fluctuates, TTD ensures the switch happens at a specific difficulty milestone—not a fixed date or block number.
Once TTD is hit, the final phase begins automatically.
Step 3: Paris Upgrade (Execution Layer Transition)
- Trigger: Upon reaching TTD
Core EIPs Implemented:
- EIP-3675: Disables Ethash (PoW algorithm) and hands block production to the Beacon Chain.
- EIP-4399: Enhances on-chain randomness generation for fair validator selection.
When Paris activates, PoW mining ceases, and Ethereum becomes fully secured by stakers.
From this moment forward:
Ethereum is a Proof-of-Stake blockchain.
🤔 Frequently Asked Questions (FAQ)
Q: Does The Merge make Ethereum fully scalable?
A: No. Scalability comes later through layer-2 solutions like rollups and future upgrades such as danksharding (part of "The Surge"). The Merge focuses solely on consensus efficiency and sustainability.
Q: Will my existing ETH change or require action?
A: No action is needed. Your ETH remains safe and usable. Wallets, exchanges, and dApps function as usual. No token swap occurs.
Q: Can I start staking after The Merge?
A: Yes—but you still need 32 ETH to run your own validator. Alternatively, use liquid staking protocols (e.g., Lido) to stake smaller amounts and receive staked ETH derivatives (like stETH).
Q: Is Ethereum now completely secure without miners?
A: Yes. PoS introduces stronger cryptographic guarantees. Attackers would need to control over 1/3 of all staked ETH—making attacks extremely costly and detectable.
Q: How does The Merge affect decentralization?
A: It enhances long-term decentralization by lowering hardware barriers (no need for ASICs), though concerns about validator centralization remain. Ongoing efforts focus on improving client diversity and distributed staking pools.
Q: What comes after The Merge?
A: Ethereum’s roadmap continues with:
- The Surge: Scaling via rollups and sharding
- The Verge: Statelessness with Verkle trees
- The Purge: Reducing storage burden
- The Splurge: Further optimizations
Final Thoughts
The Ethereum PoS Merge isn't just a technical upgrade—it's a foundational shift toward a greener, more secure, and economically sound blockchain. While it won’t fix high gas fees or speed up transactions overnight, it sets the stage for everything that follows.
