Advanced Approaches for Vulnerability Detection in Solidity-Based Smart Contracts: A Comparative Review

With the advancement of blockchain technology, Solidity-based smart contracts have become essential for automating and securing digital transactions across various sectors, from finance to supply chain management.  These contracts enable decentralized exchanges without intermediaries, enhancing transparency.  However, their immutable nature poses security challenges: any flaw in the code becomes permanent, exposing contracts to attacks and leading to financial and reputational losses.  This paper provides a comparative analysis of recent machine learning (ML) and deep l

Decentralized smart contract software service using ETHEREUM blockchain non-fungible tokens

The decentralized technologies of the Ethereum blockchain were analyzed, based on the principles of which a decentralized software service solution was proposed using a smart contract implemented in the specialized Solidity programming language. This contract acts as one of the elements of the server-client application and is the server part for processing methods of interaction with the Ethereum blockchain. The methods include a set of various functions, including for interacting with a collection of non-fungible tokens.

Real Estate Information Verification Service With the Use of the Blockchain Technology

Blockchain (blockchain — chain of blocks) — Distributed Ledger Technology (DLT). This is a combination of components that includes: peer-to-peer (P2P) networks, distributed storage, and cryptography (hashing and public-key encryption). Popular implementations of blockchain technology include Bitcoin as the electronic currency, which can be used to make money transfer transactions from one wallet to another. This paper considers Blockchain technology and the possibility of its usage to verify real estate information.
