hash – Why is Git not considered a “block chain”? – Stack Overflow

Still an interesting question: [WayBack] hash – Why is Git not considered a “block chain”? – Stack Overflow.
With my limited knowledge of both, I think git is a Merkle tree without both a proof of work and consensus system. That would make it the chain part of block chain, and the without bits the block.
How wrong am I?
It seems I still have a lot to learn about Merkle tree related stuff, so on my research list:

- InterPlanetary File System – Wikipedia IPFS is a peer-to-peer distributed file system that seeks to connect all computing devices with the same system of files. In some ways, IPFS is similar to the World Wide Web, but IPFS could be seen as a single BitTorrent swarm, exchanging objects within one Git repository. In other words, IPFS provides a high-throughput, content-addressed block storage model, with content-addressed hyperlinks.[11] This forms a generalized Merkle directed acyclic graph (DAG). IPFS combines a distributed hash table, an incentivized block exchange, and a self-certifying namespace. IPFS has no single point of failure, and nodes do not need to trust each other, except for every node they are connected to.[12]Distributed Content Delivery saves bandwidth and prevents DDoS attacks, which HTTP struggles with.[5]
