Спрашиваю для друга в Москве.  Надо менять ежемесячно крипту на фиат (наличкой), объем примерно $500 - $1000 в месяц.   Рассмотрю рекомендации только от людей со статусом на bitcointalk.org -- пишите тут или сразу в личку.
2  Economy / Scam Accusations / Scammer alert @XiaDefi on Twitter [solved] on: October 28, 2023, 03:43:34 AM
This is about account @xiadefi on X / Twitter. She scammed me for $50.  Here is a record of our exchange,

I sent her 0.03 ETH as we agreed for a retweet, but instead of performing the task, she demanded another $200.
She also threatened me that if I don't pay, she will use her account with many followers to discredit my account.
Note that my account on Twitter is @entelecheia_inc



3  Bitcoin / Project Development / Crosspass - a simple way to share passwords, encryption keys, banking info on: September 06, 2023, 06:19:41 PM
Finally Johnny can encrypt!  

I've made a new app called Crosspass that makes end-to-end encryption for dummies.  It is better than Signal et al. because it forces users to authenticate (keys) via a natural flow.

- Based on a US patent which I have received this summer.
- Available on the App Store and Play Store.

See crosspass.app for details.

I would like to hire influencers in crypto space to blog about this.  Please PM me if you are one of them.

5  Alternate cryptocurrencies / Marketplace (Altcoins) / StrongCoin account missing 3 bitcoins, lawyer needed on: February 09, 2022, 07:43:15 PM
Hello,

A friend of mine had bitcoins in StrongCoin for many years, since 2012.  In 2021 someone moved them, as can be seen in the blockchain. He tried contacting StrongCoin support but has received no response. 

Is there a lawyer who would like to take up his case to communicate with StrongCoin and to find out what happened?

Thank you,
Boris

I made a Diffie-Hellman tool that even laymen can use to establish a shared password or encryption key.  Here's a discussion thread on Hacker News:

The tool can be found at:

P.S. I think there's value to encrypt bitcoin addresses, even though they are public. This way the owners of the addresses can remain anonymous. This is analogous to having a numbered Swiss bank account.

9  Other / Off-topic / Tree Table: an outdoor standing desk on: August 14, 2020, 05:43:54 PM
I've made a standing desk that mounts on a tree.





It's held by a strap that fits snugly around the trunk. The table is stable, and I work on it all day.  On a hot day, a tree give me a cool shade; on a colder spring day working standing keeps my blood circulating and I'm warm. It's a win-win. And, I'm "enjoying the lockdown" by working outdoors instead of the sterile air-conditioned environment of the office.

The Tree Table is now on INDIEGOGO and you can support the project and get your own Tree Table when it's ready.

10  Bitcoin / Project Development / Safe way to send a bitcoin address on: July 31, 2019, 03:49:57 AM
I have been working on a secure messaging solution (email and one-off messages).  I have posted about it here, https://bitcointalk.org/index.php?topic=5159958.0

Here I just want to highlight one important use case, relevant to cryptocurrency users. How would you send someone your Bitcoin address? (Or any crypto coin wallet address)?

Even though your wallet address is public, you don't want people to know your addresses, so that they wouldn't know how much money you have received on it. Afterall, you don't publish your bank statement on your Twitter page.

What you need is a way to send the address that can't be linked to you.  I have a way you can do this so that

- the recipient of your address (someone who is supposed to pay you) will get exactly your address, rather than an impostor's address
- there will be no trace on the internet of the address, so that an adversary can't figure out that it's yours.

Looking for investors or clients.


11  Bitcoin / Project Development / Secure Email - looking for investors or clients on: June 29, 2019, 06:25:45 PM
Hello,

I have been working for over a year full time on a secure email solution.  The first six months was research: looking at what's out there and thinking.  Since October I started coding the prototype. My solution solves the problem with key exchange and javascript backdoors. It's not a gateway/proxy/server solution, but is strictly a client-side product.  Anyone can use it, and the recipient of the email does not have to be a member of the system.  My goal was to make it easy receive end-to-end encrypted email.  No browser plugins are necessary. Can be also used to transfer large files as attachments.

I will tell more to interested parties. Looking for either investors or corporate clients who want to try it out. I have been bootstrapping the whole thing on my own until now.

Thanks,
Boris
12  Economy / Web Wallets / Blockchain.info removed wallet nicknames, and I can't find my wallet id now on: November 26, 2016, 06:48:19 PM
My wallet is https://blockchain.info/wallet/shimon-boris

This used to automatically expand into a url with a wallet-id. But now it doesn't and I can't login. I tried to get my wallet-id by email, but because I have two wallets on blockchain, the automated system sent me the id to the other wallet I have.

So now -- blackchain.info support people: please email me the wallet id. Thanks.
