What are the advantages of using Ethereum over Bitcoin? (与比特币相比，使用以太坊有哪些优势?)
Bitcoin and Ethereum are both cryptocurrencies, which means they are digital currencies that use cryptography to secure transactions and control the creation of new units. However, there are several key differences between them.
Firstly, Bitcoin was the first cryptocurrency and remains the most well-known and widely used. Its primary purpose is as a decentralized digital currency, which means that it is not controlled by any government or financial institution. Bitcoin transactions are verified through a system called proof-of-work, which involves users solving complex mathematical problems to validate transactions and earn new bitcoins.
On the other hand, Ethereum was designed to be more than just a cryptocurrency. It is a decentralized platform that enables the development of decentralized applications (dapps) using smart contracts. These are self-executing contracts with the terms of the agreement between buyer and seller directly written into code. Ethereum uses a proof-of-stake system to validate transactions, which is less energy-intensive than Bitcoin's proof-of-work system.
Another key difference between the two is the block time – the time it takes for new blocks to be added to the blockchain. Bitcoin has a block time of around 10 minutes, while Ethereum's block time is around 15 seconds. This means that Ethereum transactions can be processed more quickly.
In summary, while both Bitcoin and Ethereum are cryptocurrencies, they have different purposes and use cases. Bitcoin is primarily a digital currency, while Ethereum is a decentralized platform for developing dapps using smart contracts. Ethereum also has a faster block time and uses a different method for validating transactions.
