![]() ![]() “I see the BiglyBT support more as a conversation shifter away from the ‘what’s the point of v2, nobody supports it so why should I even think about it’ towards a discussion about realizing the benefits of a transition,” Parg notes. The BiglyBT team does want to be ready for when that time comes and they see the latest release as a conversation shifter. Until that changes, things will remain the same. While users can create and download v2 torrents with the latest release, they are not backed by any torrent sites or publishers yet. Change Will be Slowįor now, however, not much is going to change. The benefit to users of this is that, when bad data is received, either due to corruption during download or perhaps from deliberate pollution by bad actors, only a small amount of data needs to be discarded and the culprit is readily identifiable. This makes it possible to verify much smaller chunks of a file as it is downloaded. Torrent users can already reap the benefits from v2’a fine-grained block hashes. Therefore we can switch from using file size as the proxy and take the guesswork out of the matching process,” Parg tells us. “With v2 torrents we have explicit file hashes for each file. Right now the feature isn’t implemented yet, but it’s an idea that’s being considered. This makes it possible to perfectly match files, which could even be done automatically. Per-File Hashes Opens DoorsīitTorrent v2 changes this, as each file within a torrent has its own hash. This is a pretty basic approach that involves some guesswork, which makes it error-prone. BiglyBT already has this option where new files are matched based on file sizes. With swarm merging, someone can download the same file from different torrents that are discovered on request. We have discussed these benefits in detail before, including the ‘swarm merging’ possibilities. “We support both hybrid and v2 only torrents for downloading, magnet metadata downloads and with all our existing features such as swarm discoveries and I2P,” Parg from BiglyBT informs us.ĭifferent torrent formats may sound like a step backward, but it’s a prerequisite for many added benefits that make BitTorrent ready for the decades to come. Older clients may be able to access the v1 swarm without change, but this is not guaranteed. BiglyBT supports these, allowing files to be downloaded via both the v1 and v2 swarms. To aid migration, there are ‘hybrid’ torrent files that contain information to construct both v1 and v2 swarms for a set of files. The v2 torrent format creates a different, stronger torrent hash for a given set of files which will result in a separate swarm from a v1 torrent containing the same files. One of the main differences users may notice from BitTorrent v2 is that it creates a new type of torrent format. These clients have yet to implement the functionality and were beaten to the chase by BiglyBT. It was first proposed by Bram Cohen in 2008 and updated and improved along the way.Ī few weeks ago, v2 support was officially added to the Libtorrent library, which is used by popular clients including uTorrent Web, Deluge, and qBittorrent. In basic terms, it’s a new and improved BitTorrent specification that includes several technical changes. This latest release includes BitTorrent v2 support, which makes it the first torrent client to support the new specification.īitTorrent v2 isn’t well known to the public at large but developers see it as a potential game-changer. The developers continued improving the software over the years and they have just released a new version with several updates. However, BiglyBT is much more than just a copy. The user interface is old-school and packed full of nifty features, just like the client it was based on. People who try BiglyBT will immediately notice that it has been created by veteran BitTorrent coders. After that project stalled, they left to create their own spinoff instead. The open-source software is created by ‘Parg’ and ‘TuxPaper’ who previously worked as the main developers of Azureus and Vuze. BiglyBT is a relatively new BitTorrent client that first entered the scene during the summer of 2017. ![]()
