While both the Bitcoin and Ethereum networks are powered by the principle of distributed ledgers and cryptography, the two differ technically in many ways. For example, transactions on the Ethereum network may contain executable code, while data affixed to Bitcoin network transactions are generally only for keeping notes. Other differences include block time (an ether transaction is confirmed in seconds compared to minutes for bitcoin) and the algorithms that they run on (Ethereum uses ethash while Bitcoin uses SHA-256).

Like other blockchains, Ethereum has a native cryptocurrency called Ether (ETH). ETH is digital money. If you’ve heard of Bitcoin, ETH has many of the same features. It is purely digital, and can be sent to anyone anywhere in the world instantly. The supply of ETH isn’t controlled by any government or company – it is decentralized, and it is scarce. People all over the world use ETH to make payments, as a store of value, or as collateral. The latest news about Ethereum mostly concerns the move to Serenity the last post-development phase of Ethereum as well as changing Ether mining’s concept from Proof-of-Work to Proof-of-Stake in order to reduce the power cost of the process.
