What is Ethereum?

Ethereum is a decentralized blockchain platform that has developed and issued its own cryptocurrency called Ether (ETH). Blockchain technology enables the Ethereum network to provide security for digital transactions.

Compared to Bitcoin, the two cryptocurrencies share similarities as well as differences, each with their own advantages and limitations. Ethereum, however, uses a Proof-of-Stake mechanism to validate transactions and also serves as the foundation for many emerging technologies that originated from blockchain.

Differences Between Ethereum and Bitcoin

In reality, Ethereum and Bitcoin share several similarities, but at the same time, there are also notable differences that attract attention from both investors and developers.

When it comes to the positioning of the networks and their tokens, the founders of Ethereum envisioned their network as a “global programmable blockchain platform.” In other words, they see Ethereum as a network where developers can build applications using its available resources. Bitcoin, on the other hand, was designed primarily as an alternative medium of exchange, separate from traditional financial institutions.

Another key difference lies in the supply. Bitcoin has a capped supply of 21 million coins, whereas Ethereum has no maximum limit on the number of tokens that can be created.

Most importantly, transaction fees between the two networks differ significantly. On Ethereum, gas fees are paid by participants who perform transactions, and part of those fees are burned by the network. In contrast, on the Bitcoin network, miners receive and cover transaction fees.

What is Ethereum 2.0 

Ethereum 2.0 is the next upgraded version of the Ethereum network, representing a transition from the Proof-of-Work mechanism to Proof-of-Stake. The goal of Ethereum 2.0 is to enhance the network in terms of adaptability, accessibility, and smoother transaction processing.

However, Ethereum 2.0 still requires multiple upgrade phases before reaching its complete version. Once fully implemented, it is expected to significantly boost the network’s capacity, enabling it to handle over 100,000 transactions per second.

The Technology Behind Ethereum

In fact, the Ethereum network incorporates several technologies into its system, as follows:

• Smart Contracts 

Smart Contracts are programs deployed and executed on the Ethereum blockchain. They consist of data and code stored at a specific network address and play a key role in managing transactional information. Smart Contracts operate according to the pre-programmed instructions without the need for human intervention or control. Additionally, they help define rules and enforce them automatically through code, making the data immutable and unalterable.

• dApps (Decentralized Applications)

dApps aim to focus on creating financial services using cryptocurrencies, enabling users to lend, borrow, speculate, and make payments without the need to share personal information.

• Ethereum Virtual Machine (EVM)

Ethereum Virtual Machine (EVM) is a program that enables a decentralized financial ecosystem. It operates by executing code across various nodes in the Ethereum network. Nodes call upon the EVM, which then processes Smart Contracts. The unit of work, called “gas,” measures computational efficiency for different operations, helping allocate resources and maintain network security.

Real-World Applications of Ethereum

When it comes to practical use, Ethereum has been applied widely in various ways, as follows:

• Ethereum and Gaming

Ethereum has been applied to virtual world gaming, with Decentraland being the most notable example. This blockchain-based game, which involves buying and selling virtual land, uses the Ethereum network to secure in-game items. Additionally, avatars, outfits, buildings, and environmental elements in the game are tokenized, serving as a medium to represent ownership.

• Ethereum and NFTs 

NFTs use tokens to represent digital items, and these tokens are created on the Ethereum network. Each token corresponds to a digital item and comes with a private key, giving the NFT owner exclusive rights to hold it. NFTs can be sold or traded, with transactions conducted on the blockchain. Once the network verifies and confirms a transaction, ownership is properly transferred to the new party.

NFTs have been applied across various industries, ranging from sports trading cards to video content.

• The Development of DAOs

Decentralized Autonomous Organizations (DAOs) are a method for collective decision-making across a network. The purpose of creating DAOs is to achieve various goals, such as developing Web3, building games, or making investments. DAOs utilize Smart Contracts and applications to tally votes from members, invest in ventures according to majority decisions, and verify actions, all without relying on third-party intermediaries.
