> Thus, unlike some other source-code management systems, Git does not (conceptually, at least) record "deltas" from one revision to the next. It thus forms a sort of blockchain, with each block containing the state of the repository at a given commit. Color me surprised, dropping the "blockchain" word in the middle of the introduction

Git is a blockchain. Being, as it is, a chain of signed blocks.

  Git is a Merkle tree as is a blockchain. https://en.wikipedia.org/wiki/Merkle_tree https://en.wikipedia.org/wiki/Merkle_tree

    It is more a DAG than a tree.

      And talking about hash attacks it becomes relevant to consider the possibility of it being just a Directed Graph

  It is still a sort of namedropping. In the sense that it is used due to the trendiness of the term. It is entirely possible and likely that it is used for didactic purposes as many people are familiar with the blockchain structure and its use of hashes.

    I thought it was a joke. The whole: blockchain isnt that inovative if you use a strict technical definition because lots of things are a chain of blocks before bitcoin was cool, meme. And honestly fair enough. The inovative part of bitcoin is not the blockchain but all the economics & game theory going on to create trust in the system

      I think this is the reason why it the parent was criticizing it. Blockchain as a term generally mean "crypto-magic-stuff on a blockchain" so for git to use it instead of a more academical Merkel trees (or Merkel DAG if they exist) sound a bit like low effort name dropping. Again it is not a criticism of the article, but it is not a criticism of the criticism either.
