Blockchain technology and internet of things: review, challenge and security concern

<span>Blockchain (BC) has received high attention from many researchers recently because it decentralization, trusted auditability, and transparency as its main properties. BC contributed fundamentally to the development of applications like cryptocurrencies, health care, internet things (IoT), so on. The IoT is envisioned include billions pervasive mission-critical sensors actuators connected internet. This network smart devices expected generate have access vast amounts information, creating unique opportunities for new applications, but significant security privacy issues emerge concurrently does not contain robust systems. provides services privacy, security, provenance systems that depends research includes analyzing a comprehensive review technologies. Moreover, proposed solutions in academia with methodologies used integrate blockchain are presented. Also, types attacks on collected classified. Furthermore, contributions challenges included literature explored, then relevant recommendations solving explored proposed. In conclusion, integration could produce promising results enhancing environment.</span>
