Для боротьби з пакетами помилок розроблено різні багатовимірні (каскадні, ітеративні) коди. Принцип роботи цих кодів полягає в послідовному використанні двох рівнів кодування і декодування даних. При цьому на кожному рівні кодування можна використовувати однакові за типом і коригувальною здатністю коди або різні. Перевагою багатовимірних кодів є їх висока коригувальна здатність, а недоліком – висока надлишковість. Розроблено двовимірну схему контролю помилок на основі модулярного коригувального коду. Модулярні коригувальні коди належать до символьних кодів, характеризуються низькою надлишковістю, дають змогу ефективно виявляти та виправляти одиничні символьні помилки. Принцип формування перевірних символів у двовимірному модулярному коді полягає в такому: спочатку обчислюють перевірні символи по рядках матриці даних; на ...

Nowadays world has a lot of decentralized applications and proposals, however the approaches and concepts decentralized software development based on the Blockchain technology is only emerging. This process is a common thing for new technologies as far as its adaptation takes time and often requires to change a usual approach to it. This article suggests a new way of safe decentralized applications development using Blockchain technologies and Ethereum platform. Ethereum platform–it’s a project that is undoubtedly second best after bitcoin for a quite long period of time. Ethereum is presented as a platform for various tasks, such as maintaining a stable application performance in case of any threats. The main object of the research are the decentralized applications, build on a Ethereum platform basis using the smart-contracts algorithm. The study helped to improve an existing crypto-token allocating model which goal is acquiring more stable performance. On the basis of improved model a new method of allocating cryptotokens in decentralized Ethereum applications was developed, defined a main stage of apps elaboration, offered an allocating crypto-token algorithm which is able to use associative tables and dictionaries.
