نبذة مختصرة : U radu je opisan način rada kriptografske strukture podataka Merkleovog stabla te se teorijski obraĎuju pojmovi poput hashiranja, pojedinih svojstava Merkleovog stabla i blockchaina. TakoĎer se otkriva uloga hash funkcija u samom radu blockchaina, odnosno Merkleovog stabla gdje se algoritmima poput provjere podataka i provjere dosljednosti stvara sustav utvrĎivanja integriteta podataka. A to je točno što je tehnologiji blockchaina trebalo da se razvije u najpopularniji decentralizirani sustav. Blockchain je otporan na zlonamjerno mijenjanje i brisanje podataka jer je svaka njegova transakcija više puta hashirana s ostalim transakcijama i blokovima meĎusobno. Bitcoin, koji je i započeo revoluciju kriptovaluta, nije jedini koji koristi ovu tehnologiju. Ethereum i mnoge druge kriptovalute koriste sličan koncept s malim razlikama u setu pravila ponašanja u mreži. ; This paper describes how the cryptographic structure of Merkle tree data works, and theoretically addresses concepts such as hashing, individual properties of the Merkle tree, and blockchain. It also reveals the role of hash functions in the blockchain itself, that is, the Merkle tree, where algorithms such as audit proof and consistency proof create a system for determining data integrity. And that is exactly what blockchain technology needed to become the most popular decentralized system. The blockchain is tamper proof because each of its transactions has been hashed multiple times with other transactions and blocks to each other. Bitcoin, which started all of this, is not the only one using this technology. Ethereum and many other cryptocurrencies use a similar concept with small differences in the behavioral rules of the network.
