The successful merge of the Ethereum Ropsten testnet marks a pivotal milestone in the evolution of one of the world’s most influential blockchain platforms. This event, completed on June 8, signals that Ethereum is entering the final phase of its long-anticipated transition from proof-of-work (PoW) to proof-of-stake (PoS). While the mainnet merge date remains unconfirmed, the Ropsten success paves the way for upcoming transitions on the Goerli and Sepolia testnets—critical steps before full deployment on Ethereum’s main network.
This shift isn’t just a technical upgrade; it represents a fundamental transformation in how Ethereum operates, with profound implications for energy efficiency, network security, and economic dynamics. As we approach this historic moment, understanding the significance of the Ropsten merge helps clarify what’s at stake—and why it matters to developers, investors, and users alike.
Final Stages of Ethereum’s Merge Preparation
For months, developers have rigorously tested merge functionality across various shadow forks such as Kintsugi and Kiln. Shadow forks are specialized test environments created by forking a small number of nodes from the existing network. These forks mirror the main chain’s state, history, and chain ID, enabling realistic simulations of post-merge conditions.
Transactions from the main chain can be replayed on these forks, allowing engineers to observe how client software behaves under real-world load. Multiple successful tests across these environments have confirmed core functionalities—paving the way for live testnet deployments.

To prepare Ropsten for the merge, a new Ropsten Beacon Chain was launched on May 30, providing the consensus backbone necessary for PoS operation. This marked the beginning of the final testing phase before broader implementation.
How the Merge Unfolded on Ropsten
The merge process occurred in two coordinated stages across consensus and execution layers:
- Consensus Layer Upgrade (Bellatrix)
On June 2, at slot height 24,000, the consensus layer activated Bellatrix—a protocol upgrade that prepared validators for the upcoming execution layer transition. - Execution Layer Trigger (Terminal Total Difficulty - TTD)
On June 3, the Terminal Total Difficulty (TTD) was set to50000000000000. Once the PoW chain reached this cumulative difficulty threshold, mining ceased, and block production shifted entirely to the Beacon Chain validators.
When the first post-TTD block was produced by stakers instead of miners, the merge was officially complete. This seamless handoff demonstrated that Ethereum’s dual-chain architecture could converge without disruption—a crucial validation ahead of mainnet deployment.
Following Ropsten, the Goerli and Sepolia testnets are scheduled to undergo similar transitions in the coming weeks. Their successful stabilization will trigger the next major step: setting a Bellatrix activation slot and TTD value for the Ethereum mainnet.
Once these parameters are finalized, client teams will release versions enabling the mainnet merge—bringing Ethereum fully into the PoS era.
The Environmental and Economic Impact of Proof-of-Stake
The transition to PoS is more than a consensus mechanism change—it’s a sustainability revolution. Estimates indicate that PoS will reduce Ethereum’s energy consumption by 99.5%, eliminating the need for power-intensive mining hardware and making the network vastly more eco-friendly.
But beyond environmental benefits, the merge brings dramatic shifts in Ethereum’s economic model—particularly in supply issuance and market dynamics.

ETH Supply and Demand Dynamics After the Merge
One of the most significant consequences of the merge is its impact on ETH’s supply-demand balance. Let’s break down the structural forces at play.
Current State (Pre-Merge – Proof-of-Work)
Daily ETH Issuance: ~14,790 ETH
- Miners receive ~13,200 ETH/day
- Stakers receive ~1,590 ETH/day
- Annual Issuance Rate: ~4.5%
- Transaction Fee Revenue: ~$10M/day (7-day average)
- Fees Burned via EIP-1559: ~85% of total fees (~$8.5M/day)
Under PoW, miners bear high operational costs (electricity, hardware, cooling), leading them to sell a large portion of their rewards—estimated at 80%—to cover expenses. This creates consistent selling pressure.
Stakers, in contrast, have minimal costs and are incentivized to hold or reinvest. They’re estimated to sell only ~10% of their rewards.

Post-Merge (Proof-of-Stake)
With mining eliminated:
- Daily issuance drops from ~14,790 ETH to ~1,590 ETH — a 90% reduction
- Equivalent to three Bitcoin halvings
- Miner sell-off disappears
- Only staker distributions remain
Let’s compare structural supply and demand:
| Scenario | Daily Sell Pressure | Daily Buy Pressure (Burn) | Net Flow |
|---|---|---|---|
| PoW | $19M | $8.5M | -$10.5M |
| PoS | $0.3M | $8.5M | +$8.2M |
Even if stakers sold 100% of their rewards, net buy pressure would still exist due to fee burning.
Why Fee Burning Equals Structural Demand
EIP-1559 introduced a deflationary mechanism: every transaction burns a portion of ETH. Unlike payments to miners (which re-enter circulation when sold), burned ETH is permanently removed from supply.
This creates genuine structural demand—users must continually repurchase ETH to participate in the network. Over time, sustained usage leads to net deflation when burn exceeds issuance.
Frequently Asked Questions (FAQ)
Q: What is the Ropsten testnet?
A: Ropsten is one of Ethereum’s oldest public testnets, used to simulate mainnet conditions and test major upgrades like the merge before live deployment.
Q: Does the Ropsten merge guarantee a smooth mainnet transition?
A: While not a guarantee, it significantly increases confidence. Successful testnet merges allow developers to identify and fix issues in a risk-free environment.
Q: Will ETH become deflationary after the merge?
A: It depends on network activity. When daily fee burns exceed new issuance (~1,590 ETH/day), ETH supply contracts—making it deflationary during periods of high usage.
Q: How does EIP-1559 contribute to ETH’s value?
A: By burning transaction fees, EIP-1559 transforms user spending into permanent demand, reducing circulating supply and increasing scarcity over time.
Q: Is there any risk to my ETH during the merge?
A: No action is required from regular users. The merge is a backend upgrade; your funds remain safe in wallets or exchanges.
Q: What comes after the Goerli and Sepolia merges?
A: Once all testnets successfully transition and stabilize, developers will set a TTD for mainnet, followed by client releases enabling the final switch to PoS.

Conclusion: A New Era for Ethereum
The Ropsten testnet merge is more than a technical checkpoint—it’s a preview of Ethereum’s sustainable, scalable future. With energy consumption slashed by over 99%, issuance reduced by 90%, and structural buy pressure replacing constant sell pressure, Ethereum is undergoing a fundamental economic transformation.
While narratives often drive short-term price movements, structural demand driven by real usage and tokenomics provides long-term support. Every transaction on Ethereum now contributes to scarcity through fee burning—a powerful engine for value accrual.
As Goerli and Sepolia prepare for their own merges, momentum builds toward the ultimate goal: a fully upgraded, secure, and environmentally responsible Ethereum mainnet. The path forward is clear—the merge is no longer a question of if, but when.
