Ethereum and Ethereum 2.0 is a decentralized platform that runs smart contracts. Smart contracts, also called self-executing contracts, are blockchain-based programs that can be deployed in the system to carry out transactions when certain conditions specified in the contract are met. Ethereum 2 will introduce a major shift from Proof-of-Work to Proof-of-Stake consensus and drastically improve network’s scalability, speed and effectiveness
Ethereum was created in late 2013 by Vitalik Buterin, a Russian-Canadian programmer and writer, who co-founded Bitcoin Magazine in 2011 and published the Bitcoin White Paper in 2008.
The Ethereum Foundation was registered as a Swiss non-profit foundation with headquarters in Zug, Switzerland in July 2014. In June 2016, the result of an effort by Vitalik Buterin to generalize his previous efforts brought about a DAO hack. An anonymous attacker took advantage of the vulnerability and drained 50 million USD in Ether from the smart contract (approximately 15% of all Ether at the time), emptying it into a child DAO under their control. Finally, the Ethereum network performed a “hard fork” to repay the funds people had invested in The DAO.
This was achieved through the use of a block that transferred all Ether from The DAO and child DAO accounts into a “refund contract” account that only permitted impacted customers to withdraw their initial investment. As a result of the DAO breach, the blockchain was altered through a hard fork in order to repay those accounts whose funds were stolen. However, the blockchain is designed to be immutable, and smart contracts are self-enforcing. As a result, this decision sparked intense debate among the Ethereum community.
As a result, the Ethereum blockchain was divided into two parts: Ethereum and Ethereum Classic. The Ethereum blockchain utilized a modified blockchain that restored all stolen cash to its original accounts, whilst the Ethereum Classic network used the original blockchain, which included the DAO breach. This split was unintentional on the part of the Ethereum developers, and it developed as a result of a clash between justice (returning stolen Ether to its rightful owners) and blockchain principles (decentralization and the immutability of the blockchain). Since then, the two blockchains have stayed divergent, and they are basically two separate cryptocurrencies with the identical origins.
Ethereum 2.0 is the next version of Ethereum. It will be a proof-of-stake network like Ark, Cardano, and Dash. With proof-of-stake the miners are replaced with validators. The new system will be much faster and more secure than the current one. Ethereum 2.0 was expected to be rolled out in 2020 but due to the covid-19 pandemic and other unforeseen circumstances. It is still being developed.
The shift from Proof of Work to Proof of Stake is an ideology shift in what makes up a blockchain network’s security model. The change from Proof-of-Work (POW) to Proof-of-Stake (POS) consensus and eliminate its scalability issues and speed of transactions.
Ethereum 2.0 is one of the most ambitious projects in cryptocurrency history.
The team behind Ethereum 2.0 goals to solve scalability, speed and security issues that arise with the current blockchain architecture that governs Ethereum 1.0.
The upgrade
The change will happen in three phases:
Phase 1: Casper FFG – Friendly Finality Gadget
Phase 2: Casper CBC – Casper Corrected at Fork
Phase 3: ETH2.0 – Ethereum 2.0
The transition will happen with a “hard fork” called Serenity that will be implemented after the Constantinople upgrade.
The Ethereum 2.0 will introduce a new way of reaching consensus in its transactions by switching from Proof-of-Work to a Proof-of-Stake algorithm called Casper, which will help achieve scalability and speed boosts for the network while also making it more effective.
The current version of Ethereum uses a Proof-of-Work (PoW) consensus algorithm which requires miners to spend time and energy in solving complex mathematical equations (and wastes related) for each block to be created and added to the blockchain. Miners compete with others through mining to solve those equations first and get rewarded proportionally as well as rewarded with Ether for doing so.
Ethereum 2.0 as the next iteration of the Ethereum platform will also be adding a number of new improvements to its smart contract language.
Ethereum 2.0 will introduce a major shift from Proof-of-work to Proof-of-Stake consensus and it will drastically improve network’s scalability, speed and effectiveness. Ethereum is based on a protocol called “Turing complete” which means that any algorithm can be run on it, so long as it does not require more processing power than the system provides.

Scalability and effectiveness
Proof of stake has higher scalability than proof of work because it only requires that you stake your coins–it doesn’t require that you put anything into mining them.
It also results in faster transactions because there are fewer validators to verify the transactions
Ethereum 2.0 is a next-generation version of the Ethereum blockchain that makes a major transition from using Proof-of-Work consensus to a new hybrid protocol called Proof-of-Stake.
The transition from Proof-of-Work to Proof-of-Stake will be done in phases, starting with the release of Ethereum 2.1 in late 2020 or early 2021. Every stakeholder in the network will have an opportunity to test this new blockchain and provide feedback before Ethereum 2.0 is launched in 2024 with its fully implemented Proof-of-Stake consensus algorithm.
Ethereum 2.0 is a proposed upgrade to the Ethereum blockchain that will be accomplished by a hard fork.
The Ethereum 2.0 network has been designed to offer more scalability and speed, as well as an upgraded consensus protocol that removes the need for mining. It will also offer more effective governance through the use of Casper-based PoS protocol which can vastly reduce transaction times and gas fees.
Ethereum 2.0 will also improve network’s scalability and speed by making it much easier for nodes to process transactions and update the state of the blockchain. The update will make Ethereum much more effective and efficient.
Furthermore, Ethereum is more of a utility platform, similar to the Apple app ecosystem, because many other products are being built in the Ethereum environment.
Still, the blockchain’s capacity to process all transactions is struggling to keep up with demand, so all of the scalability and proof-of-stake work that Ethereum’s team is undertaking on the technological side is critical. In comparison to the previous proof-of-work paradigm, proof-of-stake enables speedier transactions and lower costs. The proof-of-stake technique enables Ethereum investors to “stake” their assets in “stake pools” to collect rewards and gradually increase their holdings.
Buterin stated in May at the StartmeupHK Festival 2021’s Virtual Fintech Forum that Ethereum construction was taking longer than projected. He added that the Ethereum team predicted that proof-of-stake would take one year, but it really took six years.
Because of the possible hazards, Buterin underlined the need of having Ethereum’s “most promising option” for long-term scalability as an unique upgrade from the others. Sharding is the name given to this long-awaited function. Sharding is the technique of splitting a database horizontally in order to disperse load, minimize network congestion, and increase transactions per second. The shard chains are intended to boost Ethereum’s data storage and access capabilities.
The big change to the new network, on the other hand, suggests a unilateral shift away from decentralized planning by miners and devs and toward Vitalik Buterin and his colleagues. It also changes buyers’ expectations of earning dividends proportionate to their network ownership rank. As a consequence, Ether will mimic an investment security rather than decentralized network currency.
With an eye for detail and understanding of this exciting industry. My experience has given me an understanding of crypto trends and how to effectively break them down. I have a soft spot for NFTs and the Metaverse.
