Ethereum's merger has over. That's Important, Here's Why?


Proof of stake was formally adopted by Ethereum on Wednesday night just before midnight. Over 99% of the carbon footprint is anticipated to be reduced.

The Ethereum blockchain consumed about the same amount of electricity on Tuesday morning as the entire country of Chile. The blockchain's energy consumption significantly decreased just before midnight Pacific Time. After eight years of planning, Ethereum finally switched to a proof-of-work model, which means that the energy-guzzling process of creating ether cryptocurrency tokens is no longer used.

That action, referred to as "the Merge," has major ramifications. Coins like bitcoin and ether, according to cryptocurrency naysayers, are useless and demand a ton of electricity. The second is without a doubt factual, while the first is divisive and subjective. The carbon emissions of bitcoin and ethereum are too obvious to ignore in a time when more people than ever believe that societal climate change prevention should be our top concern.

Since 2014, before the blockchain was formally deployed, Ethereum has been planning to migrate to proof of stake. It has been postponed several times because to the technical difficulty and growing amount of money at stake. The Merge is a component of the modifications known as "ether 2.0," which transform the

After the Merge was finished, Ethereum's creator Vitalik Buterin said on a YouTube livestream, "This is the first step in ethereum's enormous path toward being a highly mature system, and there's still steps to go." We still need to scale, fix privacy issues, and make the system secure for everyday users. We must all put in a lot of effort and do our role.


"The difference between early stage ethereum and the ethereum we've always wanted," Buterin said of the Merge.

What makes cryptocurrency hazardous for the environment?

Understanding the function of cryptocurrency miners is a prerequisite for comprehending the Merge.



Imagine that you desired to mine cryptocurrency. To run software that tries to solve challenging cryptographic challenges, you would set up a powerful computer, or "mining rig." Thousands of mining rigs from all around the world are in competition with yours as you attempt to solve the same challenge. You gain the privilege to "verify" a block, or to add new information to the blockchain, if your computer decrypts the cryptography first. You receive a prize by doing so: Ethereum miners receive 2 ether ($2,400) plus gas, which are the fees users pay on each transaction (which can be as little as 0.001 ether), while Bitcoin miners receive 6.25 bitcoin ($129,000) for each block they validate.

People generally set up warehouses full of rigs for this purpose because it needs a strong computer to have a chance in this race. This approach is known as "proof of work" because computers are required to demonstrate their energy usage by solving an energy-demanding puzzle. It's how ethereum functions and how Bitcoin functioned up until Tuesday night.


According to Jon Charbonneau, an analyst at Delphi Digital, "it's what's known as the Sybil resistance mechanism." According to Charbonneau, each blockchain must be powered by a limited resource that is impossible for malicious parties to control. Power, in the form of the electricity needed to conduct a mining operation, is the resource for proof-of-work blockchains.

A bad actor would need to have 51% of the network's power in order to take over a proof-of-work blockchain like bitcoin. Since there are hundreds of thousands of computers in the network, the bad guys would need to possess 51% of the computing power in this massive mining pool. It would be quite expensive to do so.


The network is safe. Despite the prevalence of scams and hacks in the cryptocurrency industry, neither the bitcoin nor ethereum blockchains have ever been compromised. However, the drawback is clear. Energy usage increases as cryptographic puzzles get more difficult and more miners try to solve them.

Why is it known as "the Merge"?

By combining two blockchains, Ethereum changed from proof of work to proof of stake.



In contrast to other "testnet" blockchains used primarily by developers, the Ethereum blockchain that users use is referred to as "mainnet." The "beacon chain" is a brand-new network that was developed by Ethereum developers in December 2020. In essence, the beacon chain is the new ethereum.




A proof-of-stake chain called the beacon has been operating alone since it was founded 19 months ago. Blocks added to the chain by validators have contained neither data nor transactions. Like a bus doing empty routes to ensure the engine is functioning properly

The data stored on the Ethereum mainnet was transferred to the beacon chain as a result of The Merge, and this blockchain is now the main one on the Ethereum network. Using the bus as an example, it would be as if all of the commuters from the older, less effective buses were being transferred to the newer buses with more energy-efficient engines.

How does the Merge help?

In favor of proof of stake, Ethereum will totally abandon proof of work, the system that consumes a lot of energy now.



Staking is the term used in the cryptosphere to describe adding bitcoin to a protocol. Sometimes doing so can result in interest. For instance, the terraUSD stablecoin's developers promised consumers 19.5% interest on staked TerraUSD, allowing you to deposit $10,000 and withdraw $11,900 after a year (until it imploded).




Sometimes staked coin aids with protocol security, like in the case of a proof-of-stake blockchain. The more ether is staked, as we'll see momentarily, the more secure the blockchain will be following the Merge.

With the adoption of proof of stake, miners won't need to use a lot of energy to solve cryptographic puzzles in order to validate new blocks. As an alternative, they will add ether tokens to a pool. Assume that each of these tokens represents a lottery ticket: If your token number is called, you are given the opportunity to validate the following block and receive the associated prizes.

The business is still costly. A minimum of 32 ether ($52,000) must be staked in order to qualify as a prospective block verifier (who will be referred to as "validators" instead than "miners") Participants in this system validate blocks by putting up cash rather than electricity. In contrast to a proof-of-work system, which requires 51% of the network's electricity to be used maliciously, a proof-of-stake system requires 51% of all ether that has been staked. As the cost of achieving 51% of the network's capital rises, the network becomes safer the more total ether is staked.


The Ethereum Foundation estimates that electricity consumption will decrease by 99.65% because cryptographic puzzles won't be used in the system any longer.

Exist any hazards?

Absolutely. The integration has been compared to changing an airplane's engine in the middle of a passenger flight by ethereum critics, who are frequently bitcoin aficionados. The $188 billion worth of ether in circulation is also at risk in addition to the plane.

The new blockchain may contain numerous unanticipated flaws on a technological level. The security of proof of stake is a concern for critics as well. According to Charbonneau, it might be safer because of a feature known as "slashing," which essentially allows validators to have their staked ether burnt and their network access canceled if they are discovered to have acted maliciously. Unlike proof of labor, wherein if someone succeeds to hold 51% of the power, that power cannot be taken away from them, this system allows for the transfer of power.

Charbonneau remarked, "Say someone attacks bitcoin today with 51%, you can't really do much." "They could just keep attacking you since they have all the miners at their disposal. It's quite simple with proof of stake. Your money will be lost if you assault the network because it can be proven that you did so."


"You only get one bullet before that. So you can't do it once more."
