Análise comparativa de desempenho de smart contracts em arquitetura ethereum e bitcoin

Abstract

This study presents a comparative performance analysis of smart contracts implemented in two distinct blockchain architectures: the Ethereum Virtual Machine (via Binance Smart Chain) and the Bitcoin Virtual Machine (via Bitcoin Satoshi Vision). The objective was to evaluate the impact of architectural differences on transaction costs, execution time, and network usage, in order to identify the practical advantages and limitations of each platform. To achieve this goal, two reference smart contracts were developed: a message contract, representing simple storage operations, and a counter contract, designed to simulate scenarios of greater logical complexity and computational stress. Both contracts were implemented in the specific languages of each platform (Solidity for BSC and sCrypt for BSV) and executed in controlled test environments. The methodology included the configuration of an experimental infrastructure, performance testing, cost measurement, as well as the execution of attack functions to assess scalability under high load.
