If you have any interest in cryptocurrencies and the blockchain, you’ve probably heard of Ethereum. Ethereum is a programmable blockchain. The native cryptocurrency of Ethereum is called Ether (ETH). Ether is the second largest cryptocurrency by market capitalization next to Bitcoin.
The Ethereum Merge upgrade is “the most significant upgrade in the history of Ethereum1.” It’s an upgrade to a more sustainable consensus mechanism that is seven years in the making. Ethereum’s current consensus mechanism is called Proof-of-work. It relies on a computationally intensive activity known as mining to process and verify transactions on the blockchain.
At this time, the Merge is nearing its final stages of testing and development and is set for activation in Q3 or Q4 of 2022, assuming no further delays1. The Merge will replace the current PoW mechanism with an alternative protocol called proof-of-stake (PoS) – a different more eco-friendly model for securing public blockchains.
The switching of consensus protocols can be a complicated concept to try and understand. To help, the Ethereum website offers a useful analogy.
“Imagine Ethereum is a spaceship that isn’t quite ready for an interstellar voyage…The community has built a new engine and a hardened hall. After significant testing, it’s almost time to hot-swap the new engine for the old mid-flight. This will merge the new, more efficient engine into the existing ship, ready to put in some serious lightyears and take on the universe1.”
The transfer from PoW to PoS
With PoW, network stakeholders known as miners use specialized hardware to solve complex math problems. This computational work is expended in order to append new blocks to the blockchain. In exchange for their work, they are rewarded with ETH.
Under the new PoS consensus protocol, the process is different. Those who have a minimum balance of 32 ETH can stake their coins to become validators. Under PoS, validators instead of miners are the network stakeholders that add blocks to the blockchain.
The central motivation for moving away from PoW as a consensus protocol is to reduce the energy usage of Ethereum. Proof-of-stake consumes less energy. Developers anticipate Ethereum’s electricity consumption as a network will drop by more than 99.9%, and mining is expected to become obsolete on Ethereum2.
How will The Merge impact the supply of Ether?
After the Merge, the supply of ETH is expected to decrease over time, making it a deflationary cryptocurrency.
Due to a code change activated back in August 2021, each time a transaction is completed, part of the transaction fee is burned and removed from circulation forever. If we assume demand for ETH remains consistent, this means the price of every coin should rise.
How are validators rewarded?
With PoS, there is no longer a need to purchase expensive computer equipment to become a validator. Instead, only 32 ETH is required. With The Merge, validators will be rewarded for their participation by receiving interest on their staked coins allowing them to earn a passive form of income.
As the total amount of ETH staked grows, and there are more validators actively participating in securing network consensus, the returns for running an Ethereum validator will decline. In other words, the network will pay each validator less in interest for their work because there are more people participating and raising the level of security on Ethereum.
If the total amount of ETH staked decreases and there are fewer validators participating, returns will then increase to encourage additional participation.
What is developer Merge testing?
The Merge is not a simple process and there is potential for things to go wrong. So, developers and users have been testing The Merge upgrade to work through any bugs. A series of tests have been completed to ensure The Merge code is ready to go before it is fully activated. Once testing is complete, it’s a matter of patiently waiting for The Merge to be successfully activated.
