Application of Blockchain Technology and Cryptography Methods to Ensure Economic Security in the Transportation of Crude Oil

Book DOI: 10.21467/abstracts.93 h11, h12, h13, h10, h14 – internal hashes of blocks BC11, BC12, BC13, BC14; h10 – the hash uniting blocks BC11, BC12, BC13; h14 – the internal generalizing hashof block BC14; hn – the hash of final block BC14; Hn-1 – the external hash of the previous block; Hn – the external hash number n of a new block of the network. The scheme illustrates the formation of an internal block for embedding it in an external network block. The accuracy of the information is fixed by the corresponding hash, which immediately changes when any bit of the BC1, BC2, BC3 blocks is changed, and, most importantly, the filling of the primary space and the tanks of tanker is fixed. Thus, the task of tracking the origin of crude oil, as well as equipment involved in the processes of production, transportation and processing, is solved. The scheme of the blocks of the external blockchain is shown in Fig. 2. Fig. 2. An example of an external network for generating Hn hashes based on internal hn Thus, the data in the blocks are connected by hash functions and in order to change them in the next block, it is necessary to change the hash functions of all previous blocks, and this is almost impossible. The fact thateach network member has the entire database does not allow it to be destroyed or modified. The considered schemes can be used as a basis for designing networks with a distributed registry (blockchain technologies) using cryptography methods to control all processes of crude oil tanker transportation.
