What makes it "scientific"? The fact that it is a PDF and the impersonal tone?
It was peer-reviewed and published in a journal. You are probably thinking of the advertising whitepapers of scammy alt-coins and crypto-tokens. This is actually research.

Stellar Lumen
Stellar has nice properties, like a decentralised exchange built into the platform and native integration with existing financial institutions/other cryptocurrencies through anchors. But I would not say it's blockchain-free. They close a "block" every 5 seconds. Depends on what you consider a block. They use boring stuff like PostgreSQL to store the data instead of reinventing everything.
Stellar can store data on Postgres because it is just a small database of how much money each account has at each ledger. Past ledgers can be erased from the database (which makes it not a blockchain in any sense anymore).
Bitcoin has a history of all transactions organized in blocks not because it's a fancy new database technology, but because that way is the way it worked out better to keep a synced state between nodes, kind of an append-only log.
You could, if you wanted that, read the Bitcoin database and translate it into a set of rows of a who-has-how-much Postgres table.
Or, better, you could implement a Bitcoin client that stored its blocks as rows in a Postgres table, but I think it would be much more resource-intensive than the databases the Bitcoin clients are using today.
So this is basically a blockchain, but with transactions instead of blocks, and diverging-then-converging graph instead of a linear sequence of blocks (like a real family graph instead of just one-parent-one-child families common in blockchains). Looks nice, what are the problems with the approach? (the paper only lists the benefits).
can this handle a trivial Sybil attack? That seems to be the drawback of a graph or DAG-based approach. -ledger scientist
That's a thing now? :o. Please explain :).

Are you trolling? It's a scientific paper.

I'm not getting any results for it on DDG, might be a troll

Seems to be about someone creating massive amounts of privkeys and messing with verification (the fact that 51% attacks no longer exist in this approach make that irrelevant, however.) I'm not an expert on cryptocurrencies, but I don't see how that issue could be any more prevalent here than in "standard" (Bitcoin-style) blockchains.

Try reading the HTML version of Fielding's paper and tell me it looks better than the pdf. It might have been invented for that purpose, but that doesn't mean it's still suitable for it. When you are writing a paper, you want to control the presentation, not just the content.
Yeah, I'm done with this "scientific" tone, this PDF thing and so on. What is in this paper that couldn't be posted as HTML in a web page? How is PDF better compared to that?
