Yup, that's just a Merkle tree. In a blockchain, blocks occur at regularly timed intervals, and are distributed globally, which is all enforced by some distributed authority mechanism, like Proof of Work. Rumor has it that Satoshi was originally going to call the data structure a "Timechain" but wanted to emphasize the cryptographic integrity feature more than the time keeping feature.
