Abstract

Blockchain is a sequence of blocks containing a complete record of transactions as a public ledger, informing the order in which transactions occurred, and which has become an option for application development. Smart contracts are a flow of value based on terms and conditions, similar to contracts in the real world, but digital and in code. The objective of this work is to present a simulation of the smart contracts use in blockchain, to have a view of the resources consumption in the execution of operations, specifically financial costs. For this, a smart contract was designed to simulate an environment of financial donation. As a result, it was possible to evaluate the costs of smart contract methods and their impact on the number of calls in the application, reinforcing the importance of simulating environments.
