I've written a torrent client, and I'm skeptical than v2 will ever catch on. While it does solve some minor problems, it's not a large enough leap forward to justify the costs.

Yeah this definitely feels like a Python 2/3 type situation. They solved one minor issue but require the whole world to update.

I'm not even convinced they couldn't have done it in a backwards compatible way. Why not stick with SHA-1 but also add SHA-256 for verification for clients that support it?

You mean beside being responsible for ~50% of the global internet traffic in 2009? https://en.wikipedia.org/wiki/BitTorrent

Yeah, but what's the current number? I'd be surprised if it were more than 5-10% these days. 2009 was 11 years ago, the internet was a much smaller and less regulated place.

Even if it were only 5-10% of internet traffic, that’d be huge! Think about how much the internet has exploded in use since 2009.

I don’t know much about protocol version pacing, but was lack of substantial changes part of the reason it has taken 12 full years to get a client to support v2?

Youtube is 37% of all mobile traffic. [1]

that is still way WAY more than enough to justify it's utility.

Very interesting. But I'm not totally clear -- what does this mean for compatibility with v1?

The article states that hybrid torrents that support v1 and v2 can be created. But what does this mean for end-users (clients)?

Will most torrent software be upgraded to support both v1 and v2? And will a client be forced to choose from the v1 or v2 swarm, or will it be able to download from and seed to both?

I mean it seems like clients would participate in both swarms -- I'd just like to know if that's confirmed.

Also, is is possible to add v2 to existing torrents "retroactively"? Who would do that? Or would this solely be for new torrents moving forwards?

Why...? BitTorrent has been influential in lots of applications. If you really need proof that BitTorrent can move milestones, it help perpetuate sites like thepiratebay.org and assisted in the advent of modern day streaming services that both the music and movie industry neglected for years. It is also a central influence for p2p networking and file sharing.

Yeah, but it's not used anymore, from what I know. Few places use it for distribution, I guess they don't consider it worth the hassle. Blizzard was using it to distribute binaries. I guess mobile internet was its downfall as few people want to seed from a mobile connection.

CGNAT has a lot to answer for, too

Why don't ISPs bill by the gigabyte and be done with it?

It would be horrible to live in a world like that. Imagine deciding to watch a shorter film on Netflix because you will pay less.

That's basically what happens with mobile data plans in India. Fixed speeds, pay X amount per 1 or 1.2 GB

It feels like this isn't a large enough leap forward. It would be nice if BitTorrent v2 made it harder for ISPs to identify what is bit torrent traffic. AT&T artificially slows down upload speeds.

Why don't ISPs bill by the gigabyte and be done with it?

Why won't ISPs stop advertising 'unlimited' service that is actually limited to N gigabytes a month, where N is substantially lower than what's possible given the speeds they provide?

Because they can get away with it.
