Worker Proposal - smart contract

“A worker proposal is a smart contract consisting of several operations and make use of the maintenance interval to automatically do stuff.”

In this section, we examine how worker proposal smart contract was constructed. There are items and helpful steps to construct a smart contract. We want to list those items by examining BitShares blockchain components.
