While technically correct that SegWit does theoretically allow that, that is not implemented, hardly relevant (you can already fully prune all blocks while still validating), and really a detail compared to other advantages (removing quadratic hashing, simplified support for high-level protocol, ...).

<p>The name itself is a good hint as to what it actually does.</p>

<p>What we have today is a "witness" (i.e signature scripts) included in every Bitcoin transaction in non-segwit compliant transactions. This allows every full node within the Bitcoin network to verify the integrity of any transactions. </p>

<p>By removing the signatures in a Bitcoin transaction, you lose the ability to verify the integrity of the transaction. But in reality, not everyone needs to be able to independently verify the integrity of a transaction.</p>

<p>Thus, by segregating the signature from a transaction, we have a smaller transaction that describes the inputs and outputs exactly as it is. But if you want to know for sure that these are verified inputs, you'll look up the Segregated Witness set to find the corresponding scripts to validate the SegWit Transaction. </p>

The name itself is a good hint as to what it actually does.

What we have today is a "witness" (i.e signature scripts) included in every Bitcoin transaction in non-segwit compliant transactions. This allows every full node within the Bitcoin network to verify the integrity of any transactions.

By removing the signatures in a Bitcoin transaction, you lose the ability to verify the integrity of the transaction. But in reality, not everyone needs to be able to independently verify the integrity of a transaction.

Thus, by segregating the signature from a transaction, we have a smaller transaction that describes the inputs and outputs exactly as it is. But if you want to know for sure that these are verified inputs, you'll look up the Segregated Witness set to find the corresponding scripts to validate the SegWit Transaction.
