Which of the following fields are strongly related to blockchain? [i] Cryptography[ii] Game theory[iii] Centralized Computing

[i] Cryptography and [ii] Game theory are strongly related to blockchain.

Cryptography is a fundamental part of blockchain technology. It ensures the security and integrity of data stored on a blockchain. Cryptographic algorithms are used to secure the identity of participants, validate transactions, and ensure data isn't tampered with.

Game theory is also important in blockchain, particularly in the design of consensus protocols, which are used to agree on a single version of the blockchain's history. Game theory helps ensure that it is in the best interest of all participants to act honestly.

[iii] Centralized Computing, on the other hand, is not strongly related to blockchain. In fact, one of the key features of blockchain is its decentralized nature, which means that no single entity has control over the entire network. This is in contrast to centralized computing, where one central unit (like a server) has control over all computing resources.
