The new Ethereum 2.0 blockchain will use a proof-of-stake consensus mechanism to validate transactions through staking. The proof of work paradigm, in which cryptocurrency miners employ powerful computers to accomplish intricate mathematical operations known as hashes, will be replaced with Ethereum 2.0’s staking mechanism. Ethereum transactions are certified by miners before being included in the public blockchain, which consumes a higher amount of electricity.
Systems using proof of work consume a lot of electricity. For instance, the annualized electricity use of bitcoin mining is currently 127 terawatt-hours (TWh). That presently consumes more energy than the entire nation of Norway.
ETH presently uses about as much energy annually as Finland and produces carbon emissions comparable to Switzerland. Thankfully, the merger is anticipated to cut Ethereum’s carbon footprint by up to 99.95%, resolving one of the cryptocurrency’s primary objections.
Since its introduction in 2015, the Ethereum blockchain has developed into the most popular decentralized network for value exchange, Dapp development, and the development of other open permissionless systems. The capacity of Ethereum has been exceeded by this heightened interest. The network’s architecture needed to be rethought and redesigned in light of the anticipated rise in demand for it to fully realize its promise for serving all of humanity.
How does it boom?
Sharding is a technique that Ethereum 2.0 proposes to use to increase its capacity. Many of the more recent Proof-of-Stake (PoS) cryptocurrencies use this method because it enables them to scale without making significant compromises to security and decentralization.
A database can be divided into smaller, more manageable chunks using sharding. The majority of nodes, or computers, in a PoW blockchain have a complete copy of the transaction history. Especially with older cryptocurrencies that have a lot of transaction history, this entire history might consume a lot of storage space.
Instead of needing to store all of the data on the chain, sharding divides the blockchain into parallel pieces that nodes are assigned to. Throughput and transaction speed are considerably increased since more transactions can be completed concurrently.
What Are the Benefits of Ethereum 2.0?
Greater scalability
For applications created on the network with faster speeds and lower fees, Ethereum must be able to accommodate thousands of transactions per second (TPS). With the addition of extra nodes, the one-two punch of sharding and a PoS algorithm is anticipated to increase scale and result in higher TPS without requiring more electricity.
Increased safety
To prevent assaults, Ethereum needs to be as safe as it can be so that users, especially institutions, feel confident using it. The Beacon Chain stated earlier is made to aid with network security.
Improved sustainability
The bitcoin business has developed a strong focus on reducing its carbon impact. Energy usage for the PoW consensus algorithm is high. Since there won’t be any mining, Ethereum 2.0 will be better for the environment. PoS will reduce Ethereum’s energy consumption “by a factor of more than 1,000,” according to Ethereum Co-Founder Vitalik Buterin, whose vision for Ethereum is depicted in the picture below.
Future of Ethereum 2.0
The first version of the Ethereum network, known as Ethereum 1.0, was developed by Vitalik Buterin. The Beacon Chain was initially introduced in December 2020, marking the beginning of crypto Phase 0. The registration of every validator on the network is located in the beacon chain. However, the full release of Ethereum 2.0 won’t happen until the conclusion of phase 2, which means it won’t be available until 2022 or maybe longer. This makes Ethereum 2.0 different from Bitcoin in that it supports smart contracts as part of every transaction. The initial Ethereum PoW chain is known as ETH1.0.
The scalability and enhancements that Ethereum 2.0 offers will make transactions and Dapps substantially faster. Fees ought to be reduced so that both users and developers can innovate more and pay less for it. The throughputs of conventional centralized financial systems will be met and even surpassed by DeFi apps thanks to their ability to scale.
The Ethereum roadmap included long-term planning that produced ETH 2.0, which enables the network to execute more transactions while boosting security and decentralization. It will need a lot of creativity and adjustment to come up with new, user-beneficial solutions for this enormous task.
