SHA1 has a collision, so now it uses SHA256. How long until a SHA256 collision? Shouldn't the new protocol just add support for many modern hash functions, and client updates can disable support for hashes that become insecure later? Or does this introduce its own headaches? That's what SSH does, right?
Why not BLAKE3? I am really curious. I mean, since it exists, why not that over SHA256? Because it is relatively new?

That indeed is a bunch of real situations that have happened to me in 2014-2015 and some of that is still a thing. Check your privileges, sweet summer child. Like seriously — for the first 30 years of my life it was outright illegal to have a bank account in a foreign…

- new hash function
- more efficient and less error prone .torrent files
- each file in the torrent gets its own hash meaning deduplication across torrents is feasible
- backwards compatible with v1
I make P2P tools too. [0] Let me tell you this: Bittorrent is one of the few things in the space that actually ... works. It works not in the sense that there is a white paper that should work. Not in the sense that there are a few company-made swarms hosted on industrial servers that keep everyone up and alive, so that the thing gives the impression the 'P2P' network does work. Not in the sense that there is a very-…

It’s great to live a in developed world during the peace time. Sometimes you have to transfer money in and out of the country at war with it’s currency in free fall and capital controls in place. At times like that “normal” ways take about 30% of the sum as transactional overhead, while bitcoin doesn’t. Sometimes “normal“ ways just don’t work normally. Sometimes your government is actively working against your abilit…
Does this hypothetical situation you describe exist anywhere outside of the hypothetical situation posited by a character in a Neal Stephenson novel? Seriously in reality the specifics of any sort of wild situation like the one you describe matter. Which countries? Which currency? Which kind of illegal behavior? And (I ask out of ignorance) in this scenario you describe why would whatever group managing whatever bitc…

> proportionate to the attendant hype From the original comment. Also, just because it was 50% at some point, it doesn't really matter today. Paraphrasing, a technology is only as good as it's latest match result. Perl was once powering the web, nowadays you have to look at the web with an electronic microscope to find it...
This is silly. Are you actually saying that bittorrent was hyped so much that constituting half the internet was a letdown? And that Perl didn't live up to its hype because it's only common today, and not as universal as it once was?
My point is that it was a fad, it's barely used anymore and it was 50% in 2009, now its usage is much, much lower. I've seen a lot of statistics of streaming services being 20-30% of the internet each (Netflix, Youtube), so I'd be amazed if BitTorrent is more than 10% 2020 (and that's a very generous estimate), as I said previously. Anyway, it doesn't matter, there are a lot of techs that were super hyped and in the end, faded away. SOAP, CORBA, XML databases, semantic web techs (RDF, etc.), RSS, ...
> And that Perl didn't live up to its hype because it's only common today, and not as universal as it once was?
Perl is not common, it's uncommon. Let's say you're a developer in one of 100 big cities around the world, how likely it is for you to find a job developing Perl web apps? I'd say that in 80-90 of those, you can't even find that job. That's not a common tech in 2020 ;-)

I think you misunderstood how the rolling hash is used in this context. It's not used to address a chunk; you'd use a plain old cryptographic hash function for that. The rolling hash is used to find the chunk boundary: Hash a window before every byte (which is cheap with a rolling hash) and compare it against a defined bit mask. For example: Check if the first 20 bytes are zero. If so, you'd get chunks with about 2^2…
I think they understood just fine. If I discover that the file I want to publish shares a range with an existing file, that does very little because the existing file has already chosen its chunk boundaries and I can’t influence those. That ship has sailed. I can only benefit if the a priori chunks are small enough that some subset of the identified match is still addressable. And then I may only get half of a two th…

> victim of central banks diluting their dollars with printing. So, nobody in the EU or North America, then.
Perhaps a better threat scenario would have been "victim of banks confiscating their deposits", which is a much more realistic risk for people in the EU: https://www.cbc.ca/news/business/cyprus-bank-account-tax-put... (Also, the grandparent post perhaps should have given some context to the statement "Lightning made scaling possible", such as the fact that Bitcoin originally supported 32 MB blocks of transactions, be…
European leaders wanted to limit the size of the rescue loans — which are backed by European taxpayers — to €10 billion. Leaders were also reluctant to bail out Russian depositors whose funds may be the result of tax evasion, crime or money laundering.
Additionally, there are sanctions in place since the 2014 Crimean crisis.

In the case of Bittorrent they should know a little bit about how it works before they start pirating software, music or movies using it, however.
