Implementing distributed consensus mechanisms and embracing decentralization are fundamental best practices for enhancing the trustworthiness of blockchain systems. A systematic literature review titled “A Systematic Literature Review on Blockchain Consensus Mechanisms” emphasizes that consensus mechanisms are pivotal in maintaining the integrity, reliability, and decentralization of distributed ledger networks. The study highlights that these protocols ensure that all participants agree on the ledger’s state, thereby fostering trust among users. By adopting robust distributed consensus mechanisms and promoting decentralization, blockchain networks can enhance their resilience against attacks and failures, thereby strengthening the overall trust of their users.
