- Provas de Coerência Transacional para Smart Contracts em BlockhainsPublication . Bugalho, David Alexandre Aparicio; Sousa, Simão Patricio Melo deBlockchain technology is an emergent topic based on decentralization and immutability, enabling mutually untrusting parties to fairly exchange assets without the need of a central authority. Recently, the addition of blockchain programs, known as smart contracts, enabled the technology to expand upon a variety of industry sectors, already known to traditional software. Many organizations and corporates saw a growth opportunity, extending their businesses into this domain — now, though, with the blockchain twist. However, the inclusion of computation exposed a weak link in the overall blockchain security, due to carrying not only traditional software bugs, but also never before seen ones. That way, smart contracts, especially valuable ones, became enticing for hackers to exploit, which resulted in a set of tragedies where funds were stolen, among other consequences. Soon after, smart contract security became a most valuable topic of research among blockchain platforms. The Tezos blockchain is a relatively new platform whose stance values security by construct infrastructure, in consequence of the past incidents. While many smart contract security solutions were devised over the years, these have not been properly adapted nor adopted for the average developer in the community. Due to various reasons, but for one, seamless integration with the smart contract development processes is one of them. This dissertation approaches the blockchain security problem through an indirect approach, providing the developer with better accessibility and conditions for working on one of Tezos’s state-of-the-art security tools. Although it is unorthodox, it is hoped for the solution to inspire and appeal other blockchain communities by shedding some light in this unknown direction.
