What is the difference between Bitcoin and Ethereum?
Bitcoin vs Ethereum: Unraveling the Key Differences in 2024
Bitcoin and Ethereum are the two most popular and influential cryptocurrencies in the world, with a combined market capitalization of over $2 trillion as of October 2023. Both of them operate on blockchain technology, a type of distributed database that stores data in blocks that are securely linked together using cryptography. However, they have different goals and features that make them unique and suitable for different use cases. In this web page, we will explain the main differences between Bitcoin and Ethereum, and how they compare in terms of purpose, functionality, scalability, consensus, and more.
Purpose
The first and most obvious difference between Bitcoin and Ethereum is their purpose. Bitcoin was created in 2009 by an anonymous person or group using the pseudonym Satoshi Nakamoto, who published a white paper describing Bitcoin as a peer-to-peer electronic cash system. The main goal of Bitcoin was to provide a decentralized alternative to traditional money, that could be used for online payments, remittances, and store of value, without the need for any central authority or intermediary. Bitcoin is sometimes referred to as "digital gold" or "sound money", as it has a limited supply of 21 million coins, and its value tends to increase over time due to its scarcity and deflationary nature.
Ethereum was created in 2015 by Vitalik Buterin, a Russian-Canadian programmer and co-founder of Bitcoin Magazine, along with other developers and enthusiasts. Ethereum was inspired by Bitcoin, but it aimed to go beyond being just a digital currency, and to provide a platform for decentralized applications (DApps) that could perform various functions, such as smart contracts, decentralized finance (DeFi), non-fungible tokens (NFTs), gaming, social media, and more. Ethereum is sometimes referred to as a "world computer" or a "global supercomputer", as it can execute any code that is written on it, as long as there is enough computing power and gas (a unit of fee) to run it. Ethereum is also a platform for innovation and experimentation, as it supports various protocols, standards, and projects that aim to improve and expand the functionality and usability of the network.
Functionality
The second difference between Bitcoin and Ethereum is their functionality. Bitcoin has a limited and predefined functionality, as it can only process transactions that involve the transfer of bitcoins. Bitcoin transactions are simple and straightforward, as they only require the sender's address, the receiver's address, and the amount of bitcoins to be transferred. Bitcoin transactions are also irreversible, as they cannot be modified or canceled once they are confirmed on the blockchain. Bitcoin transactions are secured by cryptography, which makes them virtually impossible to counterfeit or reverse.
Ethereum has a flexible and programmable functionality, as it can process transactions that involve the execution of any code that is written on the network. Ethereum transactions are complex and dynamic, as they can involve multiple parties, conditions, and outcomes. Ethereum transactions can also be reversible, as they can be modified or canceled by the sender or the receiver, depending on the logic and rules of the code. Ethereum transactions are also secured by cryptography, but they can also be linked to smart contracts, which are self-executing agreements that can perform various functions, such as transferring funds, issuing tokens, verifying identities, and more.
Scalability
The third difference between Bitcoin and Ethereum is their scalability. Scalability refers to the ability of a network to handle a large number of transactions and users, without compromising its speed, security, or cost. Bitcoin has a low scalability, as it can only process about 7 transactions per second (TPS), due to its limited block size of 1 megabyte (MB) and block time of 10 minutes. This means that Bitcoin transactions can take a long time to be confirmed, and can incur high fees, especially during periods of high network congestion. Bitcoin is working on improving its scalability, by implementing layer-2 solutions, such as the Lightning Network, which can enable faster and cheaper transactions, without compromising the security and decentralization of the network.
Ethereum has a higher scalability, as it can process about 15 TPS, due to its faster block time of 15 seconds and variable gas limit. This means that Ethereum transactions can be confirmed faster and cheaper, compared to Bitcoin transactions. However, Ethereum still faces scalability challenges, as its network can also become congested and expensive, especially during periods of high demand and activity. Ethereum is also working on improving its scalability, by upgrading its protocol to Ethereum 2.0, which will transition the network from a proof-of-work (PoW) consensus mechanism to a proof-of-stake (PoS) consensus mechanism, which can enable more energy-efficient and faster processing, without compromising the security and decentralization of the network.
Consensus
The fourth difference between Bitcoin and Ethereum is their consensus. Consensus refers to the mechanism that allows the nodes, which are computers that run the network software and validate transactions, to agree on the state of the ledger. Bitcoin uses a PoW consensus mechanism, which requires the nodes to solve complex mathematical problems, called mining, to validate transactions and create new blocks. This process is energy-intensive and time-consuming, but it ensures the security and decentralization of the network, as it makes it difficult for anyone to manipulate or attack the network. Bitcoin miners are rewarded with newly created bitcoins and transaction fees for their work.
Ethereum currently uses a PoW consensus mechanism, but it is in the process of transitioning to a PoS consensus mechanism, which requires the nodes to stake their ether, which is the native cryptocurrency of the network, to validate transactions and create new blocks. This process is more energy-efficient and faster, but it may pose some challenges in terms of security and decentralization, as it may favor the nodes that have more ether and influence on the network. Ethereum validators are rewarded with newly created ether and transaction fees for their work.
Conclusion
Bitcoin and Ethereum are the two most popular and influential cryptocurrencies in the world, with a combined market capitalization of over $2 trillion as of October 2023. Both of them operate on blockchain technology, a type of distributed database that stores data in blocks that are securely linked together using cryptography. However, they have different goals and features that make them unique and suitable for different use cases. Bitcoin is primarily designed to be a digital currency that can be used as a medium of exchange or a store of value. Ethereum is designed to be a platform for decentralized applications that can perform various functions, such as smart contracts, DeFi, NFTs, and more. Bitcoin has a limited and predefined functionality, as it can only process transactions that involve the transfer of bitcoins. Ethereum has a flexible and programmable functionality, as it can process transactions that involve the execution of any code that is written on the network. Bitcoin has a low scalability, as it can only process about 7 transactions per second, due to its limited block size and block time. Ethereum has a higher scalability, as it can process about 15 transactions per second, due to its faster block time and variable gas limit. However, both platforms are working on improving their scalability, such as by implementing layer-2 solutions or upgrading their protocols. Bitcoin uses a proof-of-work consensus mechanism, which requires the nodes to solve complex mathematical problems to validate transactions and create new blocks. This process is energy-intensive and time-consuming, but it ensures the security and decentralization of the network. Ethereum currently uses a proof-of-work consensus mechanism, but it is in the process of transitioning to a proof-of-stake consensus mechanism, which requires the nodes to stake their ether to validate transactions and create new blocks.
