Why doesn't Bitcoin store its blockchain in a DHT, but instead makes each (full) node store the entire blockchain?
related questions: "Why doesn't Bitcoin use a DHT for choosing peers?" and "Why doesn't each node store only a portion of the blockchain?"
Full nodes don't even need to store the entire blockchain (bitcoin core has a pruning mode). They must process each block at least once to ensure they have the correct UTXO set, then the raw block data can be discarded.
