A Kaspa pruned node fully and independently validates every single transaction and block within its active consensus window. It executes the exact same validation code as an archival node. It calculates the cryptographic state changes itself. The only thing it does is discard the data once it passes the pruning point.
A Bitcoin SPV node does not verify transactions at all. An SPV node download headers, looks at the Merkle root, and says, "Well, the miners put this transaction in a block, so I guess it’s valid." It completely skips checking for double-spends or fake coins.
They are not the same at all.
You assume that because you don't have the data from 2023, you cannot verify the state today. But in a UTXO-based ledger, the current UTXO set is the condensed, mathematically proven result of all previous history. If a miner tried to invent fake coins out of thin air in 2023, the resulting UTXO set today would have an invalid cryptographic hash. A Kaspa node would instantly reject the snapshot because the cumulative Proof-of-Work headers wouldn't match.
Even on a full node in Bitcoin, if a user running a full node discovers a bad transaction from 2013 today, they cannot change it. If they try to unilaterally "blacklist" that old block, their node will simply split from the network, put itself on an isolated, useless island, and they will be left completely alone.
You are confusing data storage with consensus validation. A Bitcoin SPV node checks zero rules and trusts miners blindly. A Kaspa pruned node checks all rules for current consensus and trusts nobody. It executes full cryptographic verification of every block and transaction in its window.
If your definition of decentralization requires every participant to host a permanent archive of historical coffee purchases from three years ago on a Raspberry Pi, then yes, Kaspa doesn't fit your definition. But if decentralization means that any user can independently enforce the current rules of the network, prevent inflation, and validate their own financial state using raw math and Proof-of-Work, then a Kaspa node is as much of a full node as Bitcoin—it just throws away the trash when it's done.
Again, you don’t understand, and that’s ok. I’m used to it. Bitcoin religious zealots are many.
