The Ether blockchain has been upgraded to Ethereum 2.0, often known as ETH2 or “Serenity.” The upgrade intends to improve the ETH network’s speed, efficiency, and scalability so that it can handle more transactions and alleviate bottlenecks.
What is the difference between Ethereum 2.0 and Ethereum Classic?
Don’t worry if you already own ETH; there’s nothing you need to do; the ETH 2.0 update is taking place behind the scenes, and holders should not notice the change.
Bottlenecks have been observed by Eth-1.0 users, and there is still a need to improve the number of potential transactions per second (currently 15 to 45). The following are the two key structural changes in ETH2:
early polling suggests possible support for a 2021 minimum viable merge target
the merge comes after EIP-1559, itself slated for the London hardfork in July/August

Instead of Ethereum Proof of Work miners looking at active transactions, validators on the ETH blockchain use a consensus process called Proof of Stake. Validators are required to post a 32ETH bond in order to prevent fraud.
The dividing of a blockchain into shards is known as sharding (multiple blockchains.) Sharding increases efficiency by allowing validators to keep track of their own Shard’s information. To avoid manipulation and increase security, validators will be swapped across shards, with communication between shards via the Beacon Chain.
Beacon Chain — ETH2.0’s increased network of shards and stakers is coordinated by this system. The umbrella that connects the shards.
What Is the Distinction Between ETH1 and ETH2?
The main distinction is the “consensus mechanism” employed (confirming a transaction). Proof of work (PoW) is used in Ethereum, whereas proof of stake will be used in Ethereum 2.0. (PoS).
What is the difference between proof of stake and proof of work?
There is a need for decentralized transaction validation using blockchains like Ethereum. Ethereum, like other cryptocurrencies like Bitcoin, is currently based on the proof of work consensus process.
Miners employ the computing capacity of a machine to solve complicated mathematical puzzles and validate new transactions in this system. The first miner to solve a challenge adds a new transaction to the blockchain’s record of all transactions. They are then given the network’s native coin as a reward. This technique, however, can be quite energy-intensive.
The Work’s Proof In its current incarnation, the PoW mechanism is a computationally and energy-intensive procedure that involves solving a hard mathematical puzzle that is being employed by Ethereum miners for transaction validation.
The miner who solves the riddle the fastest wins a prize. The PoW approach is expected to encourage innovation in the renewable energy sector.
Because securing a blockchain with PoS utilizes far less computational power for block creation, it is more energy-efficient than PoW. According to the Ethereum Foundation, ETH 2.0 will use 99.95% less energy than ETH 1.0.
Proof of stake differs from mining in that users can stake a network’s native cryptocurrency and become validators instead of miners. Validators, like miners, validate transactions and ensure that the network is not executing false transactions.
These validators are chosen to propose a block based on the amount of cryptocurrency they have staked and the length of time they have staked it.
Other validators can then confirm that a block has been seen. A block can be added to the blockchain once there are enough attestations. The successful block proposition is then awarded to the validators. “Forging” or “minting” is the term for this process.
The main advantage of PoS over PoW is that it decouples energy-intensive computer processing from the consensus algorithm, making it far more energy-efficient. It also means that securing the blockchain does not necessitate a large amount of computing power.
The Ethereum mining business, which uses PoW, is extremely competitive, requiring significant investment in mining hardware and energy consumption; however, this will change with the transition to Eth 2.0, making participation easier.
The Future of ETH2
ETH2 is being released in stages, with the first, known as the Beacon Chain, going live on December 1, 2020.
The Beacon Chain adds native staking to the Ethereum blockchain, which is an important part of the network’s transition to a PoS consensus mechanism. It’s a separate blockchain from the Ethereum mainnet, as the name implies.
The Merge, the second phase, will merge the Beacon Chain with the Ethereum mainnet and is expected in the first or second quarter of 2022.
Shard Chains, the final step, will be critical in scaling the Ethereum network. Instead of settling all transactions on a single blockchain, shard chains distribute them across 64 different chains.
This also means that running an Ethereum node is significantly easier in terms of hardware because there is far less data that needs to be saved on a machine.
Shard Chains aren’t expected until 2022, but the exact date is unknown.
Even second-generation cryptocurrencies, such as Ethereum, have throughput and scalability limits.
The Bitcoin network can presently only process seven transactions per second and guarantees only 4.6, whereas ETH can handle anything from 15 to 45, which can be a bottleneck if usage surpasses this, which it does on occasion.
The ETH 2.0 network has the ability to scale to 100,000 transactions per second; by comparison, VISA averages 1700 transactions per second and claims to be capable of 24,000.
What Will the Impact of ETH 2.0 Be?
Users of the Ethereum network will be pleased since ETH will change its pricing structure, resulting in lower transaction fees.
This means that current miners will earn less per transaction for the new inclusion fee than for Ethereum’s auction-style free market, but it is expected that their cost per transaction will decrease due to PoS’s increased energy efficiency, and the number of transactions will increase as a result of the lower cost benefiting both the user and the Validator.
The lower prices and faster performance of ETH 2.0 will enable more sorts of Defi transactions, as well as new and different types of Security Tokens, NFTs, and other Distributed Finance applications that were not feasible with ETH 1.0.
With zero-knowledge rollups and optimistic rollups, ETH 2.0 will enable more complicated and less expensive smart contracts. Rollups combine all transaction data and make it available on Ethereum at a lower cost than ordinary blockchain-based transactions would.
Rollups’ associated compute load is handled off-chain, resulting in increased throughput and transactional cost-efficiency.
Sharding will democratize the Network, allowing ordinary people to utilize Ethereum on their personal devices in the future. The blockchain will become even more decentralized as the number of network participants grows.
ETH issuance will also be reduced; ETH co-founder Vitalik Buterin has stated that new token issuance under ETH 2.0 should be between 100,000 and 2 million per year, down from the current 4.7 million per year, potentially raising coin demand.
