Downtime was caused by the hosting service's network going down. Should be OK now.

An issue with the Webring addon was causing Lynxchan to intermittently crash. The issue has been fixed.

BitChan Beta v0.9.0 Release Anonymous 11/15/2020 (Sun) 19:38:41 No.3162
The BitChan beta just got released and is looking for people to try it out. It's a decentralized imageboard that runs on top of BitMessage. You can create and completely control your own public or private board, globally moderate as an owner, add admins who can also globally moderate, moderate your own instance locally as a user, upload literally anything with size limits theoretically up to 100gb. Uploads can be sent purely over BitMessage or you can choose to use a hosting service. Uploads that use hosting are subjected to heavy duty protection: every file is zipped, encrypted/password protected, the zip's header is removed and random chunks of the file are removed before being uploaded. The removed parts are hidden in the PGP encrypted message that's sent over BitMessage. Once the upload is received the zip is put back together again, decrypted, unzipped and displayed in the thread. 100% of BitChan traffic happens over tor. Private boards prevent posting from all but explicitly added IDs. The permitted ID list can be edited by the owner at any point to include new IDs or restrict old ones. On public boards any ID can post until it is banned, but because of how BitMessage works, you can always just make another ID. Communications on every board are PGP encrypted. This means that even if someone somehow guessed the board name on BitMessage (basically impossible for reasons I won't go into here), they would be unable to read anything without also having the BitChan PGP symmetric password. Owners can globally change CSS, banners and wordfilters. Owners can even wipe a board if they want. You can join and create as many boards as you want. There's also a prototype steganography thread running alongside of every normal thread. The steg thread shows decrypted steg from jpg/pngs. There are also public and private lists. Lists are just collections of links to boards or other lists. Owners can do much of the same moderation, CSS changes etc. as they can do on boards. They can be updated and edited after their creation. BitChan is fully dockerized so it is cross-OS compatible, but has only been tested with Ubuntu 20.04 and the most recent version of Whonix. I could go on about all the features (there's a lot more), but I just wanted to give you a taste. It's surprisingly fast for text only messages that total around 20kb or less and using hosting services for file attachments, taking usually only a few seconds to a minute depending on how many people are on your part of the BitMessage network. https://github.com/813492291816/BitChan
>>3162 Compile instructions?
>>3163 There's no compiling necessary. It's all python.
This is fedware. Fuck off.

>intentionally hosting it on The Glowie Router network Imagine thinking this is safe
>>3166 i've set one up for /leftypol/ and it seems to be working for us ok but some issues. it's handling 20 users ok.
>>3167 Tor is simply an additional layer of obfuscation. Assuming tor is completely compromised by LEAs, it wouldn't matter because nothing being passed over tor can be used to deanonymize the user. Before being sent, all messages are pgp encrypted before being encrypted again by BitMessage. BM doesn't send any user information in the messages anyway. No one can discern who sent what and for who. As I understand it I2p support will be added later. >>3165 Feds haven't been able to prosecute anyone who used BitMessage for perpetrating a crime. BM is battle tested.

>>3169 Feds haven't been able to prosecute anyone who used BitMessage for perpetrating a crime. BM is battle tested. This should be clarified. People who have used BM to assist in crimes, such as sales and shipping of illicit goods, have been prosecuted. One case is that of Jones (https://www.justice.gov/usao-mdfl/pr/texas-resident-charged-illegally-selling-controlled-substances-silk-road-bitmessage, https://www.justice.gov/usao/flm/press/2014/May/20140530_Jones_Complaint.pdf). However, this case was actually prosecuted due to the use of physical mailboxes and tracking through USPS. Jones was only verified as a BM user during the subsequent investigation. BM did not provide the information (through leaking etc.) to allow the prosecution to get off the ground. What is of note is that no successful ransomware attacks which involved the transfer of crypto have resulted in a prosecution. This is what is meant by 'battle tested'.

A kiosk onion hidden service is now online. You can post and upload attachments. Test it out if you'd like. There's a bug report link at the bottom of the home page. http://bitchan5zleliwr7egmn4yskth5k6ofu6qbax3y4t45k3k2plt363nad.onion In kiosk mode you can only post anonymously. There's a help page which covers pretty much everything except for the peculiarities having to do with the kisok. If you actually go through the trouble (it's not that bad) of installing it you can very easily host your own kiosk instance (and if you run you're own version you get full functionality). Kiosk mode has a permissions system which allows for multiple passwords. There are password classes. Admins, guests, guests who can only view, guests who can post. There's a lot of options. How to safely host a kiosk: Pay for VPS via mixed/tumbled crypto, sftp bitchan.tar.gz over tor, ssh in over tor, extract bitchan, uncomment random hidden service lines in torrc, make daemon, load random onion address in tor browser, upload archive with custom onion address, and you're set. This kiosk instance has a 50 second post refractory period. It works with JS disabled. The kiosk disallows board and list creation, mailbox use and prevents using BM as an attachment upload method. The only things this kiosk instance allows is 1) view boards, 2) view threads (steg included), 3) make posts, and 4) submit bug reports.
