Examples of lighthouse.protocol.Project

lighthouse.protocol.Project
A Project represents something to which pledges can be made. It is serialized using an extended form of the BIP 70 PaymentRequest message and typically stored on disk. Given a set of pledges and a TransactionBroadcaster, a Project can create a transaction that commits the payments. This class is immutable and not concerned with the storage of pledges. It is not a builder or holder for UI state, look at ProjectModel for that.
