outline the technique of sequencing records by breaking them up into blocks and arranging those blocks in a chain
recall the benefits of storing transaction data as a chain of blocks such as quicker consistency checks and faster lookups
recall the fundamentals of blockchain technology such as the storage of records across a sequence of blocks
recall the use of the Ethereum state in verifying the sender's Ether balance to ensure they possess the funds being transferred in a transaction
recall what constitutes a blockchain and how they can be used to store a sequence of records
recall when a miner can claim mining rewards and how the other nodes in the Ethereum network will validate its claim
