If you need guidance in the area of cryptographic hashing and how it ensures immutability of transaction data, this multiple-video series is an invaluable tool. Inspecting hash values of downloaded files checks whether a file has been tampered with during the download process, and in blockchains, checks for alterations in the blockchain. This 8-video course helps you learn to recognize the role played by hashing and the practical benefits-faster consistency checks and lookups-gained by storing transaction data as chains of blocks. Learn to describe the Merkle tree data structure and its unique storage method, how it preserves ordering and facilitates searches, and how to outline steps related to verifying transactions in the Ethereum blockchain network, such as identifying the role of digital signatures in authenticating transactions and ensuring their integrity. Review Ethereum's balance verification procedures for senders, to make certain the sender possesses the funds being transferred. Learn how to prevent replay attacks by implementing the transaction nonce.
