Guys? Do we still need a distributed decentralized git repository?

Thank, fixed.

We don't need thousands and thousands of Bitcoin code repos across the world. It is good if so (and it is forked 24k times), but to fight the censorship it is enough to have more repos than the censor controls or may shutdown. I mean imagine we have a China censored app code hosted in lets say 5-7 different countries like USA, France, Russia, India, Brasil and Algeria. It will now be possible to shut one or two repos in one day, but it will result in attracting more attention to the app and thus people create more repos. Even small modern projects have hundreds of forks - cloned repos. It will be impossible to kill such a project by censoring it in a single country.

When people do not control what they host it is good in an ideal world - every project is distributed across the galaxy and nobody knows where exactly it is hosted and by whom. But that creates an opportunity to attack this distributed system with spam. And that is where I see a flaw and why I propose to give users the control of what they host. That is the reason. If we can somehow manage to get rid of it - that would be perfect.

Thanks, I fixed the typo and found one more.

Decentralization vs Anonymity. They are complimentary, but what is more important for modern crypto users - that is a very interesting question, actually.

The address. We try to figure it out do users change the address every time and do they understand why and how it works or just "use the wallet and don't care".

2All:
Thanks for everyone!
We need more replies. Please, help!

UPD: the reddit tread in case you find it interesting https://www.reddit.com/r/Bitcoin/comments/cqpq06/who_are_bitcoin_users_today_who_are_you_username/

Smart. That's why Bitcoin was created - you don't need banks to store your money anymore.

set the password for the wallet, store the password in several secure places. Or even parts of password.
Store the private key somewhere in several secure places.
Be happy.
Don't forget to explain your children or your mom where to get it in case your death. I'm not kidding. We all can die suddenly in a car crash or so.
Cheers.

I just thought maybe we do not need to store the data spreading it across the network. Maybe it will work better if you allow users to decide about what projects/repos they want to host. Like it is done in bittorrent protocol.

So if I want to protect some project from censorship I could host exactly this project's repo only.

Thank you to everyone who already passed the survey!

Thank you. Yes, we actually do not care about your profession at that time. Maybe we should. I will bring your feedback to the team. And yes, we are focused on the way you use crypto, not how you get it: do you pay for services and goods; do you just buy beer of weed (small spending), or you bought a 8k tv directly for crypto (I wish one day it will be as usual as pay with fiat) or you do not spend your crypto yet hodling or trading only - we want to understand how people use crypto so far: is it a hodling/trading thing only or no.

Thank you.
No, I will explain it later after the survey.
And no, we are not a part of some new/old exchange and do not work for exchanges anyhow.

I agree, never supply any sensitive information anywhere. We tried to make the survey unpersonalized as much as possible. In the meantime I would appreciate if some of you will submit any contact information so we could ask some questions to better understand our respondents. But it is totally optional.

Yes, in a good way, and yes - I understand that this topic is very private and sensitive. One more time - we never ask for your private data like real name or address or phone number. We literately do not need it.

One more time, thanks to everyone. Please, could you help spreding the info about the survey. I posted at Reddit too. https://www.reddit.com/r/Bitcoin/comments/cqpq06/who_are_bitcoin_users_today_who_are_you_username/

If anyone have some suggestions about other places where to post - I'd appreciate any suggestions.

sorry, forgot to mention one thing. see pm.

If you have some ideas or questions to add - feel free to post it here.

this will allow to find users who uses bitcoin in real life and distinguish them hodlers.

yes, 'traders' (as I'm, for example) and 'users' like one of my friends who mines at home and pays for the phone or beer.

we plan to do that once in a year, if it will be accepted by community. and that will give us the long-term profiling.

please name them and I include them right now. (the problem with this list - it is too big)

Thank you, guys.

It is better if number of responses is big enough. If it is too small then some group may influence the results.

The purpose is, as I mentioned before, to create a portrait of Bitcoin users.

I can't agree

to make system fail proof you need to duplicate data and store some additional info too. That means you *must* allow to store more data than you store yourself in the network. Assuming we have only 50% nodes online 24/7 you need to store in about 1:2 ration to make it possible.

how can you check that i really have the data not just downloaded, saved hashes and deleted all the files?

Hi, guys.

Sorry for the clickbait title

I’m conducting an interdisciplinary study in collaboration with two really cool guys. One of its purposes is to draw a psychological portrait of cryptocurrency users taking into consideration their unique individual characteristics as well as similarities. Such as a degree of risk-taking, focus on particular topics in the cryptocurrency field, decision-making features.

The survey affects a fairly broad layer of diverse information on cryptocurrencies; the information received will be used as supportive of the economic and mathematical analysis of cryptocurrencies for our study.

One of my colleague's postgraduate specialization is mathematical modeling, numerical methods, and program complexes. Another one – is a psychologist with deep knowledge in big data science.

Getting back to the survey, I have to mention that I do understand, it's very private stuff I'm asking you to share, that's why I made the survey anonymous. But if you would like to tell me more, you can leave your contact info, so we could chat or discuss something later.

Here is the link: https://docs.google.com/forms/d/e/1FAIpQLSddAVVNX0sH4D0dax1I5UHZD1KTA2odKOMBQLHbXq8jYa_1Fg/viewform?entry.1445050497=bitcointalk

I would appreciate any feedback.

My goal is to reach 1000 responses to have representative data - however, the more is the better. I will provide the results of this survey right here later.

Thank you!

> you store for me I store for you type system

I thought about that and as I think - that may work for small teams who share their own data.
I can even imaging the system with encryption and possibility to prevent excluded team member to continue reading the repo: a team owner just needs to publish new encryption and decryption keys personally for each member encrypted by this member's public key.

As a conclusion  - that may work for small teams

> On your second statement, a way to do so that would allow it to remain free is to identify the users.

It doesn't sound quite good
Anyway it is very easy to be identified but store enormous amounts of data in repo. It will require other users to reserve space to store other's files in ratio much bigger than 1:1 or even 1:2. This is obviously an attack vector here. If we do limit users in space available for free it just make an attack a bit more difficult to do but still to easy to trust that approach.
So anyway we come to the system where one needs to pay for the space. In such kind of situation most of the users will go back to GitHub or GitLab.
By thus we end up focusing on pro devs and pro teams like Bitcoin team. This is not bad, but that niche may be too marginal and not profitable for the system making it too small to resist attacks.

I'm not saying we do not have to try. Only that we has to think thoroughly.

there are two problems we need to solve:

1. github is not the repo only. It is an ecosystem for developing projects with bug tracking, issues, voting, comments, reviews, etc.
To create a decentralized clone of github you'll need to reproduce all that features.

2. to create a distributed decentralized repo hosting you need to create a storage with multiple times duplicated data. GitHub is free for opensource projects and paid features for private projects. How that can be reproduced in distributed ecosystem?

Git is decentralized as is. It stores all the history locally and sends a copy to GitHub AND/OR any other repo you would like. GitHub is just a part of decentralized git ecosystem. It simplifies communication. But I agree - it is good to use more than one repository. And in case of Bitcoin code it is crucial to use several different private repos owned by different people.

> hash(passphrase+seedX)

that operation reduces security due to attacker can brute force quicker with a single hash iteration

OK, you're right. We have a passphrase and without #0 it is just a millisecond to try. With #0 each passphrase will take a minute to try.

why do we need #0 if it's so easy to brute force it then?

no, if you loses both seeds you die

Edit: yep, if I lose one of #1 or #2 seeds it gonna take a month to brute force it of a couple of weeks with 50% probability if I'm lucky guy.
If I lose both seeds I'm in the deep trouble even if I'm extremely lucky.
