What You Need to Know About the Ethereum Merge Update

What is the Ethereum Merge and Why is it So Important?

Since the creation of Ethereum, Vitalik Buterin has stated that the current protocol is an intermediate version and will be upgraded to version 2.0. This upgrade has been in development since the early days of Ethereum's existence. However, we truly witnessed the birth of Ethereum 2.0 with the launch of the Beacon Chain in late 2020. The Beacon Chain was designed as a network to manage Ethereum during its transition to Proof-of-Stake (PoS). Since late 2020, users have been able to send 32 ETH through a smart contract to become validators in the PoS version of the Ethereum network. Today, the Beacon Chain operates in parallel with the Ethereum mainnet, which uses the Proof-of-Work (PoW) version to secure the network.

However, starting with The Merge update, the Beacon Chain will validate blocks on the ETH network, and consequently, this is the version from which Ethereum will transition to Proof-of-Stake. Even after this implementation, additional steps will be necessary before the final version of ETH 2.0 emerges. Nevertheless, The Merge represents significant progress as it marks the end of the Proof-of-Work protocol that Ethereum has used since its inception. This transition is crucial because it addresses several key challenges, including energy efficiency, scalability, and network security. The move from PoW to PoS is expected to reduce Ethereum's energy consumption by approximately 99.95%, making it a more environmentally sustainable blockchain platform.

When Will the Ethereum Merge Update Take Effect?

The Ethereum Merge has been a highly anticipated event in the blockchain community. Following the development timeline, key figures from the Ethereum Foundation, such as Tim Beiko, one of the main ETH developers, expressed approval for the creation of the Kintsugi testnet version. Danny Ryan also confirmed the progress on social media platforms, stating that the implementation was proceeding as planned. Additionally, Joe Lubin, one of the co-founders of Ethereum, indicated in his statements that the transition would occur within a specific timeframe, though exact dates were subject to final testing and validation.

The development team conducted extensive testing to ensure a smooth transition. The final major test took place on the Ropsten testnet, which merged with the new Proof-of-Stake network. This comprehensive testing phase was critical to identify and resolve any potential issues before the mainnet merge. The transition of Ethereum to a new consensus algorithm is a technically complex task, especially for a network that processes such a large volume of transactions. Furthermore, the network faces intense competition from other blockchains often referred to as "Ethereum killers," such as Solana and Avalanche. There is no room for error in this critical upgrade.

What Will Happen to the ETH Staked in the Beacon Chain Smart Contract?

Since late 2020, these Ethereum tokens have remained locked, as Vitalik Buterin clarified that the 32 ETH sent serves to secure the Beacon Chain and will only be unlocked after The Merge update. Thus, the earliest stakers whose tokens have been staked since late 2020 faced a situation where, at that time, 1 ETH was valued at less than $1,000. Currently, they stand to gain significant profits, and it can be expected that some of them will cash out their ETH and take their profits.

However, this scenario was anticipated by Vitalik, who planned and configured a mechanism to avoid such selling pressure. Every 6.4 minutes, only 4 validators will be able to unlock their 32 ETH (throughout the entire period). This amounts to approximately 900 validators per day. On average, 28,800 ETH can be withdrawn from staking per day. Currently, the daily trading volume of ETH is around 10,000,000 ETH, and the maximum supply is approximately 116 million ETH. The amount of ETH that can be withdrawn from staking per day represents 0.29% of the daily trading volume and 0.02% of the total supply.

This is a relatively small amount, as these figures assume that validators will sell 100% of the ETH they withdraw from staking. This is not the most likely scenario, as among validators, there will be those who want to exit staking but do not want to sell all their ETH. Additionally, this situation would mean that only exits from staking are occurring, without new participants entering. Many participants may become involved in the staking process, as up to this point, many institutions have avoided participating in validation due to concerns related to the "lock-up period." They did not risk depositing assets into staking without the ability to redeem them at any time. All miners or a portion of them who mine ETH through PoW may also want to participate in validation through staking.

The difficulty bomb is a mechanism in Ethereum designed to gradually increase the difficulty of mining new ethers, which should incentivize miners to leave the network or transition to the new version of the network. If developers manage to complete The Merge according to schedule, they will not need to postpone the creation of the bomb mechanism, which will soon make the task more difficult for ETH miners. This mechanism serves as an additional incentive to ensure a smooth transition to the Proof-of-Stake consensus model.

Conclusion

What does this mean for crypto investors? There are potentially many users who will want to sell ETH after The Merge update; however, there are also many new potential participants. Moreover, currently, the staking reward in the ETH 2.0 version is approximately 4.5-5.1% annually. However, after the successful completion of The Merge, validators will not only receive income from ETH inflation but will also earn from transaction fees. This means we are moving toward potentially higher yields than we have today.

It is important to note that after the merge, the inflation rate of ETH may even become negative. Currently, ETH inflation stands at 4.1%. Since the deployment of the new ETH version, which facilitated the burning of ETH through the London hard fork, we have seen inflation of only 1.4%. ETH inflation is likely to be significantly lower after the merge. Consequently, there is a probability that the price of Ethereum will increase after the merge, especially considering that the deflationary nature has become a key value factor for BTC.

Layer 2 solutions serve as a bridge until The Merge update. They will likely remain useful even after the implementation of the new ETH version. These scaling solutions will continue to play a crucial role in enhancing transaction throughput and reducing gas fees, complementing the improvements brought by the Proof-of-Stake transition.

In conclusion, ETH may find increasing applications after the completion of The Merge update. The combination of improved energy efficiency, enhanced security through staking mechanisms, and potential deflationary tokenomics positions Ethereum favorably for future growth and adoption. The successful implementation of The Merge represents a significant milestone in blockchain technology and demonstrates Ethereum's commitment to continuous improvement and innovation in the decentralized ecosystem.
