Examples of org.ethereum.core.Transaction

org.ethereum.core.Transaction
A transaction (formally, T) is a single cryptographically signed instruction sent by an actor external to Ethereum. An external actor can be a person (via a mobile device or desktop computer) or could be from a piece of automated software running on a server. There are two types of transactions: those which result in message calls and those which result in the creation of new contracts.
