Thx!
For now not that much, but there is still talk in review.
Few other talk are currently evaluated by the program committee about the privacy. As a security oriented conference, we require a highly technical talk and security oriented, which not fit with a lot of proposals. That being said, it's a great topic for our other conference : building on bitcoin.

Added talk of Greg Sanders and Kalle Ale in the topic

Added talk submission deadline

Hello everyone, I'm one of the organizer of the https://breaking-bitcoin.com conference along with Elizabeth Stark, Kevin Loaec and Nicolas Bacca.

It's an international, dev oriented conference about Bitcoin security and many things around it in Paris on 9 and 10 September.

I heard there will be some workshop @Paris the week before the edcon, will you be there?

go go short! good idea! we need guys like you!

Because of newupdate on storj today I wasn't able to run some test before. I used this file to run my test : Name: aaabb.zip, Type: application/zip, Size: 24848251 bytes.

UPLOAD

storj
test 1 : 1:51
test 2 : 0:56
test 3 : 0:56
test 4 : stopped after 7mn, seems stuck but no error message displayed
test 4 bis : 1:14

DOWNLOAD

storj
test 1 : 2:13
test 2 : 1:49
test 3 : 0:27
test 4 : 0:29

My result on download are a bit weird but I think this is because I run 11 drive share on storj in the same time (and there is a lot of activity on the network at the moment). In the other hand upload had a great improvment with the last version.

Stay tuned for other test and feel free to publish your.

thanks for those informations, I'm looking deeper into it. This thread will need a constant update because things are moving fast, I think publish a new test about storj tomorrow, for maid it will be around the 24th August and for SIA as soon as possible

as you can read there is a limitation of 25Mb file on MAID and, but I didn't wrote it, a limitation of how many PUTS (I trying to figure it out what is it exactly) you can do. SIA & STORJ have both 6 duplication, so you need to upload the file 6 time on SIA network to finish your upload. btw storj release a new version of the software today so it will change soon for them, and SIA do a lot of update too (I'm running on 1.0.1 version)

Those following test are not accurate for many reason : I don't have a good internet connection, I've several p2p softwares connected at the same time (BTC core, SIA, STORJ share, MAID) and a lot of internet page are open on my computers (>60). MAID alfa only allow file of less than 25Mb so I used this file to run my test : Name: aaabbb.zip, Type: application/zip, Size: 24848251 bytes. I ran storj on debian, sia & maid on w7. I used default setup for all. Those test are for me just a photo of what's available today, but they are all moving fast to improve their software, feel free to run your own test and share it here
