Imran Bashir

Warto dobrze zrozumieć działanie łańcucha bloków. Ta nowatorska technologia intryguje badaczy, technologów i świat finansjery. Najlepiej jest znana z powiązań z bitcoinem i innymi kryptowalutami, jednak to rozwiązanie ma wielkie znaczenie również w finansach, administracji, multimediach i wielu innych branżach. Przejrzyste i kryptograficznie bezpieczne przechowywanie niemodyfikowalnego zapisu transakcji jest właściwością, która decyduje o wielkiej atrakcyjności łańcucha bloków. Bez wątpienia warto dobrze zaznajomić się z tą technologią i nauczyć się wykorzystywać ją w praktyce. Ta książka jest zaktualizowanym i uzupełnionym wydaniem świetnego przewodnika po świecie blockchaina; skorzysta z niej zarówno programista, jak i prezes konstruujący strategię swojej firmy. Znalazło się tu wyczerpujące omówienie technicznych podstaw łańcuchów bloków i systemów rozproszonych. Przedstawiono mechanizmy związane z kryptowalutami i pisaniem aplikacji wykonywanych w zdecentralizowanej maszynie wirtualnej w łańcuchu bloków Ethereum. Pokazano też inne rozwiązania z tego obszaru, w tym biznesowe platformy łańcuchów bloków rozwijanych w ramach projektu Hyperledger. Okazuje się, że technologia ta znakomicie uzupełnia internet rzeczy, a zwiększanie skalowalności łańcucha bloków daje nowe, fascynujące możliwości. W tej książce: podstawy przetwarzania rozproszonego, decentralizacja procesów i systemów wprowadzenie do kryptografii i sieci bitcoina techniczne zagadnienia związane z Ethereum i inteligentnymi kontraktami wprowadzenie do Web3 i do projektu Hyperledger informacje o zastosowaniu łańcucha bloków w różnych dziedzinach aktualne prognozy o przyszłości technologii łańcucha bloków Blockchain: w sieci węzłów rozproszonych nigdy nic nie zaginie!
