Key takeaways
– Ethereum is a programmable blockchain with no central administrator.
– It has two account types: externally owned accounts (EOAs) and contract accounts.
– Only EOAs can originate transactions; contracts act when they are called.
– Ether is divided down to wei: 1 ether = 10^18 wei.
– A transaction carries nonce, gasPrice, gasLimit, recipient, value, data and a signature.
– The nonce orders transactions and prevents them from being replayed.
