Does the 100+ GB blockchain database contain every transaction?

Does the 100+ GB blockchain database contain every transaction since the beginning, or only a digest of them?

I've read Nakamoto's paper and I see:

the spent transactions before it can be discarded to save disk space [...] Merkle Tree [...]

thus this question: is the 100+ GB blockchain already the result of a space-saving lossy process?

Blockchain contains every confirmed transaction since the beginning. There are some tricks to save disk space of course.

What is discarded in the blockchain then, according to Nakamoto's paper? – Basj – 2017-10-11T12:28:25.653

In Bitcoin Core's database, there are no tricks to save disk space assuming you run a non-pruning node. – alcio – 2017-10-11T12:40:53.530

I mean pruning, but I do not want to mention complicated things in simple answer to a simple question – amaclin – 2017-10-11T12:53:09.423
