Título del libro: 2021 9th International Conference In Software Engineering Research And Innovation (conisoft 2021) Título del capítulo: Tender System Verification with Satisfiability Modulo Theories
A tender process consists in competing offers from different candidate
suppliers or contractors. The tender winner is supposed to supply or
provide a service in better conditions than competitors. Tenders are
developed using centralized unverified systems, which reduce
transparency, fairness and trust on the process, it also reduces the
ability to detect malicious attempts to manipulate the process. Systems
that provide formal verification, decentralization, trust and
transparency can mitigate these risks. Satisfiability Modulo Theories
provides a formal analysis to prove correctness of tender properties,
verified properties ensures system reliability. In addition one
technology that claims to do decentralization is Blockchain, a chain of
distributed and decentralized records linked in a way such that
integrity is ensured. This paper presents a formal verified,
decentralized and automated proposal model, based on Satisfiability
Modulo Theories and Blockchain technology, to make system procurement
tenders more reliable, transparent and fair.
