1  Bitcoin / Development & Technical Discussion / An approach to recover change addresses from old wallet.dat backups on: June 10, 2025, 07:46:04 PM
We made this little guide that may help people recover funds lost to change addresses, from their old wallet.dat backups

https://trade.nestex.one/docs/recover_old_wallet.pdf

You don't actually need to move funds to test if this methodology works! You can also 'test' the premise noted in the guide by creating a wallet (labelled 'wallet A' as per the guide), backing it up, and then generating many more addresses and now you have a 'wallet B'. Then restore 'wallet A' on a completely different computer and you should have the private keys that match 'wallet B', which means recovery complete!

- If you do share this guide, please do so under the CC BY license and try to use this PDF as-is.
- If it does add value we'd like to hear back from you! No we don't need a donation. Just tell me it worked for you, that's my happiness.

The intent here is to help people out. There is no commercial perspective here.

Also, many thanks to bias for guiding me with the right way & place to share this. Here's a big THANK YOU to an awesome member of the bitcointalk community!

Hope this helps someone!

IMO, anything that can help out anyone is always welcome. Especially if we are talking about such a serious issue. Maybe it would be good to make an additional post in another section of the forum that has more visibility. Like Beginners & Help, or Development & Technical Discussion for BTC. Wink
2  Other / Off-topic / RNG testing & certification service on: December 31, 2024, 09:01:15 PM
So I've been on bitcointalk for some time now and I notice a large number of gambling oriented services. A friend in the US runs a testing & certification company, and I'm making this post on request. Also because I feel it will add genuine value to the community here.

Amile Institute (www.amileinstitute.org) is a testing and certification platform that offers
1. self-study certification for Six Sigma (yellow, green and black belt)
2. RNG testing and certification (statistical randomness, die hard, chi square, bot testing)

The benefit of using this service is the online verifiability of certification.
Verification URL: https://www.amileinstitute.org/verify-rng.aspx
Reference of an actual certification: 49544173597264082937

I would encourage interested parties to communicate with the Amile Institute team on support(at)amileinstitute.org or on the phone number provided on their website. Feel free to ask me anything you have in mind here, although I can't answer as an official support person.

Hope this helps someone and wishing you all an awesome 2025

3  Economy / Exchanges / NestEx Crypto Exchange - in BETA on: December 05, 2024, 10:39:52 AM
Announcing the BETA launch of Nestex at https://trade.nestex.one

We welcome traders, new coins and even miners! Check out our proof of reserves and proof of safety - we ensure our data is backed up every step of the way and want our users to feel secure while they are with us.

(Though you should still withdraw coins to a cold wallet once you're done trading, since #notyourkeysNotyourcoins)

Original post:

Hi everyone,

We're a startup aiming to setup a crypto exchange that doesn't force users to gamble. Also we'd like to be maybe a bit more transparent about what we do and how we function, so there's genuine trust with our users (sort of taking ideas from the open source movement).

Our core team is multi-regional, and we're still a few steps away from doing a soft launch.

So I won't be making a pitch today. We're asking for inputs and perspectives.

Our thoughts:
0. Of course minimum or zero KYC. While we want to do AML compliance (probably using Chainalysis & Elliptic so the crypto sources are not outright dirty), we also wish to have our users feel safe. Big qn: Jurisdiction??
1. Focus on helping the user keep their money safe by offering positive wealth creation methods... Which means avoiding derivatives, minimizing HFT, providing bot-hosting at our own premises for better bot performance, etc.
2. Also pledging/staking would be there and our trading team would leverage those funds - we won't loan out those funds to derivatives traders as many others do.
3. This means we can also aim to get insurance for those funds, because those are then operational stakes and not simply 'deposits'.
4. We would only do crypto to crypto. No on/off ramping; we might tie up with a ramp service for this but let's see.
5. While we're using cloudflare and crypto-friendly servers, is there anything else we can do to keep things safe? For our users and for us of course.
6. We have a few investors currently, and while they've committed decent funds in both cash and crypto, we're told more funds will be required. Naturally we are putting in 100% of our own crypto and a large chunk of our own cash reserves. The investor's role here would be to give us liquidity for crypto movement and hard cash for the company's operations.
7. There are some liquidity providers we've spoken with, however most of them are very fussy on kyc. We will handle that at our end and ideally not expose our users' kyc at all. There are a few who jump directly to 'show me the money' without any talks on kyc so not sure how genuine they are.

I asked chatgpt about some of these things but the darn thing keeps rambling on and on... sheesh.

Anyways inputs would be greatly appreciated. I may edit this post to to request further inputs.

PS: If you'd like to check out our prelaunch site, its https://nestex.one - happy to receive feedback on the site as well!

Other notes:
- Some of our fees have changed over a period of time, unfortunately it appears we could not adequately function with a 'sell-side-only fee'. The updated fees have been notified on the 'fees' page.
- We have an additional constraint imposed by our legal team, involving high risk users. Situations that would trigger an SAR (Suspicious Activity Reporting) in a KYC'd platform scenario, would in our case result in a platform ban.
