Abstract— Nowadays, the implementation of advanced technology is using the principle of blockchain technology to secure the data communication of social media through the public network.  However, each user wants to secure data communication and modern secure technique to protect their data. The integrity, confidentiality, and digital signatures are verified by secure hash algorithms (SHA). The hash code is generated from a variable length input message by a hash function that is processed by SHA. Several researchers have proposed many hash algorithms that used additive keys constant and initial value as the basic parameter of the cryptographic hash function. These key constants for all input messages are openly known and these are constant for any variable length input message.  In this research, we are eliminating the key concept of the cryptographic hash function by using the decentralization principle of the blockchain. So that the design and implementation of a new decentralized blockchain-based secure keyless hash algorithm (NDBCKSHA) to evaluate the performance of the hash function by generating 384-bit fixed-length hash code and comparing its analytical analysis and experimental results in python 3.9.5 programming language. 
