This article proposes a mathematical model for quantitatively assessing the cyber resilience of modern blockchain platforms. Constructing the mathematical model, the authors proposed representing the architecture of a blockchain-based information system as four layers: the cryptographic algorithm layer, the blockchain core layer, the smart contract layer, and the decentralized application layer. A study of typical vulnerabilities was conducted for each layer, and a list of countermeasures to counter potential threats was proposed. Then, key elements and their impact on the system’s cyber resilience were identified. As a result, a mathematical model for assessing the cyber resilience of blockchain platforms was developed. Based on the analysis of the model, it was experimentally demonstrated that a cyber attack carried out at a lower layer affects all higher layers of the blockchain platform, and cyber resilience at the current layer can only be effectively ensured if it is ensured at the previous layer.
