What is the difference between Bitcoin and Ethereum

Bitcoin and Ethereum are two leading cryptocurrencies that dominate the digital asset market. Both use blockchain technology to ensure security and transparency of transactions, but their goals, technical characteristics, and areas of application differ significantly. In this article, we will analyse the differences between Bitcoin and Ethereum in detail so that you can understand their unique features and choose the right asset for your needs. The difference between Bitcoin and Ethereum lies not only in their functionality, but also in their approaches to development, scalability, and market role.

History and creation

Bitcoin was created in 2009 by a mysterious developer or group of developers under the pseudonym Satoshi Nakamoto. Its goal is to offer a decentralized digital currency that operates without the involvement of central banks or governments. Bitcoin became the pioneer of cryptocurrencies, laying the foundation for the entire industry.

Ethereum, on the other hand, was born later, in 2015, thanks to an idea by Vitalik Buterin. It was conceived as a platform for creating smart contracts and dApps (decentralized applications), which expanded the capabilities of the blockchain beyond simple financial transactions. Ether, Ethereum's native currency, is used to pay transaction fees and support the network.

Purpose and functionality

The main difference between Bitcoin and Ethereum is their purpose. Bitcoin (BTC) was created as a digital currency, an alternative to traditional money. It is often called "digital gold" due to its limited supply and ability to store value. Bitcoin is focused on conducting secure transactions and storing value.

Ethereum, in turn, is not only a cryptocurrency, but also a platform for developing and executing smart contracts that automate processes without intermediaries. For example, smart contracts are used in DeFi to automate loans or in NFTs to confirm ownership of digital assets. Ether (ETH) serves as the "fuel" for these operations, paying so-called "gas" fees.

Consensus Mechanisms

One of the key technical features that highlights the difference between Bitcoin and Ethereum is their consensus mechanisms. Bitcoin uses Proof of Work (PoW), where miners solve complex mathematical problems to add new blocks to the blockchain. This process requires significant computing power and electricity, making Bitcoin energy-intensive.

Ethereum also initially used PoW, but switched to Proof of Stake (PoS) in September 2022 in an upgrade known as “The Merge.” In PoS, validators lock up (or “stake”) their ETH to confirm transactions, reducing energy consumption by 99.9% compared to PoW, as you can read more about on the WhiteBIT Blog.

Offer and Issue

Bitcoin has a fixed supply of 21 million coins, making it a deflationary asset. New coins are created through mining, and their supply is reduced approximately every four years in an event called a halving. For example, in 2024, the block reward dropped to 3.125 BTC.

Ethereum does not have a hard supply limit. However, with the introduction of the EIP-1559 update in 2021, a portion of transaction fees are burned, which can create deflationary pressure depending on network activity. This makes the issuance policy of this cryptocurrency more flexible, but less predictable.

Transaction Speed ​​and Scalability

Transaction processing speed is another area where Bitcoin and Ethereum differ. Bitcoin adds new blocks roughly every 10 minutes, which limits its throughput to 7 transactions per second. This makes the network slower and more expensive when demand is high.

Ethereum processes blocks every 12-15 seconds, allowing for about 30 transactions per second. It also works hard on scalability through upgrades like Danksharding to increase network capacity.

Smart contracts and applications

Bitcoin vs. Ethereum is particularly clear in its support for smart contracts. Bitcoin was not originally designed for complex software operations. While the Taproot update in 2021 added limited capabilities for smart contracts, their functionality remains minimal.

Ethereum, on the other hand, was originally created as a platform for smart contracts, which are self-executing programs with pre-defined conditions. This allows for the creation of complex applications such as decentralized exchanges (Uniswap), NFT platforms, and DAOs (decentralized autonomous organizations). For example, the ERC-20 standard is used to create tokens based on Ethereum.

Community and Development

Bitcoin has a large community, but its development is slow and conservative, with an emphasis on security and stability. Updates like the Lightning Network aim to improve scalability, but are being implemented gradually.

Ethereum has an active developer community that is constantly working on improvements. Updates like the move to PoS and sharding plans demonstrate the network's commitment to innovation and adapting to market needs.

Market Position and Adoption

Bitcoin remains the leader in terms of market capitalization, accounting for about 64% of the cryptocurrency market as of June 2025, and you can learn more about it on Investopedia. It is widely accepted as a means of payment and an investment asset.

Ethereum is the second-largest blockchain project and is the foundation for many blockchain projects. Its ecosystem supports innovation in DeFi, NFTs, and other areas, making it attractive to developers and investors.

Future Development

Bitcoin continues to develop scalability solutions like the Lightning Network to speed up transactions and reduce fees. Ethereum, for its part, is working on improvements like Danksharding to increase throughput and support the growth of the dApps ecosystem.

Conclusion

What is the difference between Ethereum and Bitcoin? Bitcoin is a secure digital currency focused on stability and value preservation, while Ethereum is a flexible platform for blockchain innovation. Both cryptocurrencies play an important role in the digital asset ecosystem, and the choice between them depends on your goals: Bitcoin is suitable for long-term investments, and Ethereum is for participating in new technology projects.
