As noted in the preceding section, centralized applications are well-suited to certain situations. However, in the recent past, there has been an increased market for decentralized applications, with the faster adoption and adaptation of the blockchain technology. The blockchain paradigm promises a bevy of disruptions and transformations when realizing and running decentralized applications across multiple industry verticals. The issues that face centralized systems and applications are nullified in decentralized services and solutions. Typically, decentralized systems are owned and operated by different organizations and, hence, the security of decentralized software is technologically tightened. The much-touted unbreakable and impenetrable security of software systems is guaranteed through the decentralized approach. The peer-to-peer (P2P) interactions facilitated by the decentralized approach is turning out to be a silver bullet for many recent use cases. The faster maturity and stability of blockchain technology is clearly driving IT professionals and organizations toward the production of decentralized systems. The blockchain paradigm also resulted in the new concept of smart contracts, which leads to the realization of adaptive applications.
