Ethereum 2.0 has three enhancements that will improve scalability, security, and sustainability.
Ethereum originated in 2013 as a spark in co-founder Vitalik Buterin's eye. That's when he published the project's whitepaper, albeit the Ethereum network wouldn't go live until 2015.
In the meantime, there was the Ether sale in 2014, when early purchasers could purchase part of the now-second-largest cryptocurrency using bitcoin. Back then, Ether powered the Ethereum network as a payment mechanism for network transactions, and it still does so today.
From PoW to PoS
Ethereum, like Bitcoin, was founded on the proof-of-work (PoW) consensus system. The PoW data serves two purposes:
The PoW algorithm, on the other hand, is not flawless, and the shortcomings — such as long transaction times and high gas costs — were too significant to ignore. A notable example is the rise of the Ethereum-based CryptoKitties game. The game, which used an early form of non-fungible tokens (NFTs), became so popular that it clogged the Ethereum network, slowing transactions and driving up costs.
Another use case that has highlighted the significance of an efficient network is the advent of decentralized finance, or DeFi. While the DeFi market's total-value-locked (TVL) has skyrocketed since exploding in 2020, its expansion has been limited in several respects. Some engineers have moved on to other blockchains, while institutions have mostly stayed out of the way until the problems are ironed out. Ethereum's increased scalability and more predictable fees are anticipated to further upset conventional banking.
This is where Ethereum 2.0 enters the picture. Ethereum 2.0 is being built in order for developers to avoid shooting themselves in the foot with their own ingenuity. This is a significant update of the old network to one that is more scalable, which might speed the general adoption of blockchain.
Among the most significant modifications is a shift in the consensus procedure from PoW to proof-of-stake (PoS). Staking will increase involvement in protecting the Ethereum network, resulting in a more decentralized blockchain.
What Were the Original Ethereum Protocol's Flaws?
The version of Ethereum published in 2015 was revolutionary, but extraordinary demand for the network uncovered certain flaws. These issues may be divided into three categories:
A network that is congested: The blockchain has become overcrowded, which is not desirable for attempting to achieve worldwide acceptance. To ensure security, each computer node on the blockchain must validate transactions, which delays transaction speeds.
Inadequate disk space: As the Ethereum network increased in popularity, running software known as nodes became more challenging. The trick is to find a way to expand Ethereum's size and power without jeopardizing its decentralization.
High energy consumption: Ethereum's usage of electricity to maintain the PoW consensus mechanism for network security is not long-term sustainable.
The Ethereum team aimed to resolve these challenges while preserving the network's most crucial feature: decentralization. Though it is far from straightforward, Eth2 is the way to obtain better scalability and security without becoming a centralized network.
Now that we've established how far Ethereum has progressed, let's look at where it's going. Ethereum 2.0, also known as Eth2 and Serenity, is a significant update to the blockchain network. While not the first update, it is the one that is intended to propel Ethereum to total-value-locked (TVL) bubble status.
It is a major project on the part of the developers that will not be completed overnight. Instead, Ethereum 2.0 is unfolding in stages, the first of which happened in 2020 with Phase 0, often known as the Beacon Chain.
The Beacon Chain is a PoS implementation that runs alongside the PoW network and is currently being battle-tested. In August 2021, Ethereum executed the London hard fork, which increased the stability of gas costs on the Ethereum network and added a deflationary approach to the protocol's monetary policy. With each step comes greater features and improved performance, eventually leading to the destination of Ethereum 2.0, a PoS network.
What Are Ethereum 2.0's Advantages?
Ethereum 2.0 will provide a slew of new features that are sure to entice even more developers to join the network. The three major enhancements are as follows:
Greater scalability: Ethereum must be able to accommodate thousands of transactions per second (TPS) in order for applications created on the network to run faster and with lower costs. The combination of sharding and a PoS algorithm is projected to increase scalability by adding more nodes, resulting in higher TPS without consuming more power.
Greater security: Ethereum must be as safe as possible in order to resist assaults and give users, particularly institutions, confidence in its usage. The previously stated Beacon Chain is intended to aid with network security.
Greater sustainability: Reducing one's carbon impact has emerged as a key subject in the cryptocurrency sector. The PoW consensus algorithm uses a lot of energy. Because there will be no more mining, Ethereum 2.0 will be better for the environment. According to Ethereum Co-Founder Vitalik Buterin, whose vision for Ethereum is illustrated in the picture below, PoS would reduce Ethereum's energy usage "by a factor of more than 1,000."
What's the hold-up?
Ethereum 2.0 consists of three distinct improvements, each of which is a mammoth job in and of itself.
Beacon Chain: Introduced in 2020, this technology added staking to the network and laid the path for future improvements. While the Beacon Chain is still in testing mode, it is operational and will ultimately become the foundation of Eth2.
Merge: The Ethereum merger is likely to take place in late 2021 or early 2022. The Beacon Chain will be linked with Ethereum's mainnet at this point, allowing for staking on the Ethereum blockchain while putting a stop to mining.
Shard Chains: This depicts the breaking of the Ethereum network into stages, which will result in increased capacity for processing transactions and storing data. Sharding chains are scheduled to be installed in 2022.
Ethereum is one of the most popular cryptocurrencies, second only to bitcoin in terms of market capitalization. The transition to Eth2 is a significant set of events that will resolve the network's difficulties and may lead to widespread acceptance of the blockchain while perhaps boosting the Ether price in the meantime.
