i have to warn that you'll face many skepticism since those who download the backup need to trust you.

No trust is needed. The torrent equipped bitcoin node still queries its peers for the most work header.

But if the file is corrupted or contain invalid block, then you wasted some time and few hundred GB of internet data.

But whenever this node needs a block with a certain hash, it can just see if such a block is present in the torrent and use that instead of asking its peers for it.

I don't get this part of your statement. OP seems to backup Bitcoin Core files where one .blk file which contains data from multiple blocks.

not your keys, not your coins!

I really appreciate the effort, but as Leo and Greg pointed out, I don't see the need for something like this. There is no need to 'back up' the blockchain, since it's distributed on thousands of nodes already. It's not like backing up / archiving a certain piece of data that is hosted on a single, centralized server - something I actually do like to do, e.g. archiving Bitcointalk posts or news articles.

Except that it skips the most time consuming validation (signatures) up to a block height specified by assumevalid (defaulting to 80400/Aug2023). So that initial part of history could very well be bottlenecked by download speed.

unless you are on relatively lower power hardware, this isn't the case because script validation is highly parallel and all the other processing ends up bottlenecking.

This has been tested in the past and torrent + validate was a massive slowdown. Admittedly that was years ago, but if it's not true it must be because of limitations or defects in the node software (e.g. causing it to not achieve the potential download speed) as there is no reason using a torrent and separately validating should be faster.

For the majority of people, the rate limiting step for the IBD is the validation, not the download itself. If you sync via Bitcoin Core normally, then it validates as it goes.

If you download this torrent, then you will have to download first and validate second, and it will probably take longer than if you had just used Core to download and validate simultaneously.

There is also zero risk of downloading malware by syncing via Core than there is from downloading random torrents.

Hello Bitcoin Enthusiasts,

I'm thrilled to introduce a project I've been passionately working on - a dedicated torrent for the latest version of Bitcoin Core. Recognizing the challenges faced by many in dealing with the large size of blockchain files, my project aims to simplify this process.

I appreciate your effort. Although i have to warn that you'll face many skepticism since those who download the backup need to trust you.

There's no need to include wallet.dat, setting.json and debug.log files.

This torrent isn't just a one-time thing. What sets it apart is that it includes all the original blockchain blocks, acknowledging their significant size. To keep everyone in sync with the latest data, I am committed to providing daily updates. This ensures you have continuous access to the most recent blockchain information.

And here's the best part - downloading this comprehensive blockchain backup is completely free! My goal is to make blockchain accessibility easier and more efficient for everyone in our community, from beginners to advanced users.

For those interested in this initiative or having queries, I am all ears and ready to assist. I'm looking forward to your feedback and hope this project will be a valuable asset to all of us in the Bitcoin community.

Thank you for your support, and let's keep the blockchain strong and accessible!
