What actually makes this a blockchain? That it uses a Merkle Tree?

Is a CT log a blockchain?

A blockchain is a just a linear merkle tree.

Put differently, it's like a branching DAG with economic incentives to always treat the longest path as "master."

Quite a lot like a Git repository: you usually want to follow the branch with the most cumulative work on it.

It's more of a tree than a DAG : you'll never have merging in a blockchain.

A tree where the longest path is considered the real branch.
