Block-hash of blockchain framework against man-in-the-middle attacks

Payload authentication is vulnerable to Man-in-the-middle (MITM) attack. Blockchain technology offers methods such as peer peer, block hash, and proof-of-work secure the payload of process. The implementation uses hash on blockchain testing using White-box-testing security tests distributed system practitioners who are competent in MITM attacks. analyisis results before implementing show that still plain text, so data confidentiality has not minimize passive voice. After system, white-box Wireshark gives result sent been well encrypted safe enough. percentage test gets 95% which shows securing from attacks relatively high. Although it succeeded attacks, a vulnerability other cyber needs improvisation.
