Bitcoin and Ethereum are the two names most often compared in the crypto market. They are both public blockchains, and each has its own native coin, but their design goals, issuance rules, and use cases differ greatly. This article compares them across several dimensions.
$BTC and $ETH are the native coins of Bitcoin and Ethereum, respectively, but they serve different purposes. Currently 77,664.3 (24h +0.42%).
Origins and positioning:
Bitcoin launched in 2009, and the title of its white paper was “A Peer-to-Peer Electronic Cash System.” Bitcoin’s scripting functionality was deliberately designed to be very limited. Its core purpose is to securely record who owns how much bitcoin and facilitate the transfer of value.
The Ethereum white paper was published by Vitalik Buterin in 2013, and the mainnet launched in July 2015. Ethereum aims to be a platform that can run general-purpose smart contracts, allowing applications such as tokens, DeFi, and NFTs to be built on it using contracts.
Their issuance rules differ:
Bitcoin has a total supply cap of about 21 million coins. The block reward is halved once every 210,000 blocks. After the fourth halving in April 2024, the reward dropped to 3.125 coins per block.
Ethereum has no fixed cap on its total supply. New ETH is issued as staking rewards to validators; at the same time, since the London upgrade (EIP-1559) in 2021, the base fee for each transaction has been burned. Whether the supply increases or decreases depends on which of these two sides outweighs the other.
Consensus and accounting methods:
Bitcoin has always used proof of work (PoW), with miners competing to produce blocks using computing power. On average, a block is produced every 10 minutes. In September 2022, Ethereum switched to proof of stake (PoS) through “The Merge.” Validators who stake ETH participate in producing blocks, with blocks scheduled at 12-second intervals.
Their accounting methods are also different: Bitcoin uses the UTXO model, a bit like having “change” in different denominations in your wallet. Ethereum uses the account model, more like a balance in a bank account.
How to understand the differences:
Bitcoin upgrades very conservatively, prioritizing simple rules and network stability, which is why it is often compared to “digital gold.” Ethereum upgrades more frequently, prioritizing programmability and ecosystem growth, and is often called the “world computer.”
These comparisons are just ways to help explain what each one is designed for; they don’t represent a view on their prices. Also, when using various applications on Ethereum, in addition to price volatility, you should pay extra attention to the risks inherent in smart contracts.
My take:
Understanding the design differences between the two won’t tell you which one to choose, but it can help you make sense of news and discussions about upgrades, issuance, and transaction fees. Understanding the fundamentals can help you avoid some pitfalls, but it can’t replace risk management.
