The Ethereum Merge Explained!
4 min read
Ethereum is at the heart of the blockchain revolution it has a vast community of developers and projects on top of it and plans to improve it are underway to increase transactions, reduce gas fees etc.
Both Bitcoin and Ethereum participants are required to use powerful and energy-hungry GPUs to solve a complex mathematical problem to produce a block on the network and this is called
In this article, we shall look at all the key terms in regards to this
🔹 The London Hard Fork
It was launched in August 2021. EIP-1559 has changed Ethereum’s market mechanisms to pay for transaction fees.
The London Hard Fork was a set of five Ethereum improvement proposals (EIPs). EIP-1559, included in the London Hard Fork, aimed to change the speed and incentivisation of Ethereum mining.
Ethereum Gas fees were indeed a pain for us (especially developers) and this fork helped minimize and optimise these fees but they are still high.
🔹 The Mainnet
Mainnet is the primary public Ethereum production blockchain, where actual-value transactions occur on the distributed ledger and is used in contrast with
Mainnet, those other networks are used for testing purposes and some are private networks.
There is only one public Ethereum Mainnet. Ethereum relies on proof-of-work. In the
proof-of-work, miners must complete complicated puzzles to validate financial transactions on the blockchain.
🔹 The Beacon Chain
Beacon Chain was one of the blockchains launched on the Ethereum network with the goal of accelerating the adoption of blockchain technology at the enterprise level.
It went live in December 2020 aiming at increasing scalability and capacity across the network.
It will introduce
proof-of-stake to Ethereum. This is a new way for you to help keep Ethereum secure. Think of it like a public good that will make Ethereum healthier and earn you more
ETH in the process.
In practice, it will involve you staking
ETH in order to activate validator software. As a validator, you'll process transactions and create new blocks in the chain.
🔹The Merge | Docking.
The current Ethereum Mainnet will "merge" with the Beacon chain proof-of-stake system.
This will mark the end of
proof-of-work for Ethereum and the full transition to
The Merge was originally referred to as
Sharding is the process of splitting a database horizontally to spread the load – it's a common concept in computer science. In an Ethereum context, sharding will reduce network congestion and increase transactions per second by creating new chains, known as
🔹 Miners Vs Validators
Staking and becoming a validator is easier than mining (how the network is currently secured). And it's hoped this will help make Ethereum more secure in the long run. The more people that participate in the network, the more decentralized and safe from attack it will become.
So this merge will see miners become validators in the new Ethereum and no more usage of high intensive CPUs and GPUs hence energy friendly.
The Ethereum community is pushing for all efforts to be focused on the switch to
proof-of-stake (PoS). The Ethereum PoS chain is currently running and underwent its first hard fork (Codenamed
Altair) in October 2021.
We are expecting it to be shipped in this second quarter of the year!

🔹 ETH Effects
ETH on the Ethereum network under the current
proof-of-work (PoW) consensus engine will be unaffected by the switch to the proof-of-stake (PoS) consensus engine once
The Merge occurs.
ETH 2.0 will not be a new coin. It's just the underlying consensus mechanism changing.
