Abstract

The automation of business processes via blockchain-based systems
allows for trust, reliability and accountability of execution. The link that con-
nects modules that operate within the on-chain sphere and the off-chain world is
key as processes often involve the handling of physical entities and external ser-
vices. The components that create that link are named oracles. Numerous studies
on oracles and their implementations are arising in the literature. Nevertheless,
their availability, integrity and trust could be undermined if centralized architec-
tures are adopted, as taking over an oracle could produce the effect of a supply-
chain attack on the whole system. Solutions are emerging that overcome this issue
by turning the architecture underneath the oracles into a distributed one. In this
paper, we investigate the design and application of oracles, distinguishing their
adoption for the in-flow or out-flow of information and according to the initiator
of the exchange (hence, pull- or push-based)
