ShinyBlock: Multi-Protocol Blockchain Simulator and Enterprise Ledger Framework

An interactive framework for simulating blockchain protocols using a hybrid 'R-Shiny' and 'Python' architecture. The package provides tools to visualize peer-to-peer network maps, manage supply chain logistics on-chain, and execute cross-border settlements via smart contract logic. It leverages the 'reticulate' package to perform standardized cryptographic operations, including 'SHA-256' hashing, 'Merkle' Tree construction, and 'ECDSA' (Elliptic Curve Digital Signature Algorithm) key generation. This tool is designed for pedagogical demonstration and rapid prototyping of distributed ledger requirements.
