Transactions

Transactions are cryptographically signed instructions from accounts. An account will initiate a transaction to update the state of the Ethereum network. Transactions always originate from an externally owned account (a smart contract can not initiate a transaction).
Transactions, which change the state of the EVM, need to be broadcast to the whole network. Any node can broadcast a request for a transaction to be executed on the EVM; after this happens, a validator will execute the transaction and propagate the resulting state change to the rest of the network.
