| Popis: | Scaling and securing data exchange in distributed systems are important directions for scientific research. Known solutions provide certain level of security but lack some qualities required for wide usage. Among the obstacles are scaling distributed solutions and constructing exchange between separate robust distributed ledgers. The paper presents multidimensional blockchain— an approach to building robust distributed ledgers based on the notion of blockchain. The solution can be implemented in two approaches: block mode and state machine mode. A general security analysis, mathematical security analysis, and GUC-framework analysis are performed. Mathematical analysis is based on existing works on security of one-dimensional blockchain and consensus algorithms. A GUC-model is created to prove security of multidimensional blockchain. It is proven that multidimensional blockchain securely implements robust distributed ledger and provides secure inter-system exchange given that search and verification protocol is secure. The work is a basis for further research towards implementation of scalable robust distributed ledger. |
