What is Ethereum and how does it differ from Bitcoin?

What is Ethereum?

Ethereum is a decentralized, open-source blockchain platform that enables the creation and execution of smart contracts. It was proposed by Vitalik Buterin, a young Russian-Canadian programmer, in late 2013, and the network went live on July 30, 2015. Ethereum's native cryptocurrency is called Ether (ETH), and it is used to facilitate transactions and incentivize participants to contribute computational power to the network.

How Does Ethereum Work?

Ethereum operates on a blockchain, similar to Bitcoin, but it has its own unique features and capabilities. The Ethereum blockchain is a distributed global network of computers, known as nodes, which work together to maintain the network and validate transactions. The nodes store a copy of the entire blockchain, ensuring transparency and security.

While Bitcoin's primary purpose is to serve as a peer-to-peer digital currency, Ethereum's main goal is to enable the development and execution of decentralized applications (dapps) and smart contracts. Smart contracts are self-executing contracts with the terms of the agreement directly written into code. They automatically execute when specific conditions are met, eliminating the need for intermediaries.

Key Differences Between Ethereum and Bitcoin

Although Ethereum and Bitcoin are both blockchain-based platforms, there are several crucial differences between the two:

1. Purpose and Functionality

Bitcoin was created as a decentralized digital currency to enable secure and borderless transactions. Ethereum, on the other hand, was designed as a platform to facilitate the development of decentralized applications and smart contracts. While Bitcoin focuses on financial transactions, Ethereum offers a more versatile infrastructure for various applications beyond currency.

2. Blockchain Design

Bitcoin and Ethereum have different blockchain designs. Bitcoin's blockchain primarily functions as a ledger to record transactions, whereas Ethereum's blockchain operates as a decentralized computer capable of executing smart contracts. Ethereum's blockchain is Turing-complete, meaning it can solve any computational problem, while Bitcoin's blockchain has a more limited scripting language.

3. Consensus Mechanism

Bitcoin uses a consensus mechanism called Proof-of-Work (PoW), where miners compete to solve complex mathematical problems to validate transactions and add them to the blockchain. Ethereum initially used PoW but has been transitioning to Proof-of-Stake (PoS) with the introduction of Ethereum 2.0. PoS relies on validators who hold and "stake" their Ether to secure the network, reducing energy consumption and increasing scalability.

4. Supply and Inflation

Bitcoin has a capped supply of 21 million coins, ensuring scarcity and introducing deflationary properties. In contrast, Ethereum does not have a maximum supply limit. However, there is an issuance limit of 18 million Ether per year to control inflation. Ethereum's issuance rate is expected to decrease significantly with the transition to PoS and Ethereum 2.0.

5. Development Community

Bitcoin and Ethereum have their own distinct development communities. Bitcoin's community is more focused on financial applications and has a strong emphasis on decentralization and censorship resistance. Ethereum's community is broader, attracting developers interested in building decentralized applications, conducting token sales (ICOs), and exploring new use cases beyond finance.


Ethereum and Bitcoin are both significant players in the cryptocurrency and blockchain space, but they have different goals and functionalities. While Bitcoin revolutionized digital currency, Ethereum expanded the possibilities of blockchain technology by enabling the development and execution of smart contracts and decentralized applications. Understanding these key differences is essential for anyone interested in the potential of blockchain technology and its impact on various industries.
