smart contracts

The article explores the application of blockchain technology in the field of arms sales accounting. The authors examine the main methods of forming such technology, including distributed ledger, hash functions, cryptographic protection, smart contracts, consensus protocols, decentralized network, transactions, genesis block, decentralized governance, and public key. The authors analyze the potential of these methods in creating an efficient and secure arms sales accounting system.

The advent of smart contract technology in blockchain networks has ushered in a new era of possibilities for implementing complex decentralized finance protocols. Over time, these protocols have gained significant traction, reaching a Total Value Locked (TVL) of over 150 billion US dollars. While blockchain networks offer inherent benefits such as immutability, transparency, decentralization, and security, they still grapple with a critical challenge – the inability to ensure a predictable order of transactions within produced blocks.

Many food contamination incidents have occurred during the last decade which has proven the failure of the food supply chain management system to track the food, money, and information movement within the food supply chain.  Many models have been established. This paper presents the design and implementation of the new model providing real-time data acquisition, monitoring, and storing on a tamper-proof blockchain of the main food supply movement.
