How about I offer to escrow this for free for the two of you?

To do that, I'll need to know what to do upfront, and you'll both need to agree to that.
Things like: account name, payment address, what to change (password? email?) to secure the account, you name it.

Lets say the current block is at height 648,940. An actor of the network (no full node, no light node, even smaller than a light node) who does not store a chain of blocks neither a chain of block headers (like spv-clients does). This actor wants to verify the existence and correctness of a block by checking the finality.

For example: He requests the block header of block 600,000 and 6 finality headers to make sure that this block is correct. If the responding node is able to provide 6 (or even more) finality headers, the actor can be very sure that this block is correct and part of the actual Bitcoin blockchain.
That's the risk of using a SPV wallet: you must trust a third party. It doesn't make sense to ask for a specific block, and makes even less sense for them to create an old side chain.

A very simple solution to avoid this is to run your own full node.

I think it won’t be bad if forum’s budget will be used to rent some strong vps/servers that are available in pretty good prices by Hetzner and other hosting/colocation providers.
As much as I'd like that, I think it's a bad idea. One of the strong perks of user/community-created content is that the forum Admin doesn't have to spend time on it.

$5000 AWS code

Common sense tells you this isn't possible without someone getting screwed over.

DireWolfM14 used to escrow these things, but he stopped doing this because it's a scam.
This sums it up nicely:
I've since learned that most of the buyers are most likely email spammers, and the sellers are often creating these accounts by violating the TOS of Amazon.

TL;DR Don't buy this.

Can someone please tell me how long it takes for Chipmixer to process transfers out?
I sent some coins into their mixer, mixed it and decided to withdrew my entire chips, by sweeping them to a different address. It's been well over an 3 hour and no show on blockchain nor in my wallet.. What's up with that?
I guess the time-delay is on purpose (to improve privacy), but I can't find what range is used.

From the screenshot, i see you're using Brave Browser + Tor.

Try use Tor Browser instead since CloudFlare can detect if you use Tor Browser and would allow you access this forum directly.
That would explain why the link with the captcha-code still asks to solve a captcha: it's Cloudflare, not the forum software.

In September 2018: Cloudflare ends CAPTCHA challenges for Tor users:

The new Cloudflare Onion Service needed the Tor team to make "a small tweak in the Tor binary," hence it will only work with recent versions of the Tor Browser

In your scenario, the attacker has 10% of the total hash power, so for every block the attacker adds to its branch, the main chain will add 9 blocks. The attacker's branch will be rejected by every node in the network long before the attacker can add 6 blocks.
This makes a 10% attack quite useless, and it's the reason why such an attack is usually referred to as a 51% attack.

With some luck though, someone with less than 50% of hashing power can find the a block before the majority finds one. Let's assume someone tries a 40% attack. That gives him:
40% chance to be the first to find 1 block.
16% chance to be the firstt to find 2 blocks.
6.4% chance to be the first to find 3 blocks.
2.6% chance to be the first to find 4 blocks
1% chance to be the first to find 5 blocks.
0.4% chance to be the first to find 6 blocks.

And that's with 40% of hashing power. With 10%, there's a 0.0001% chance to reach 6 blocks faster than the other miners. That makes paying a million dollars to rent 10% of all hashing power for 10 hours a complete waste of money. If, however, you can get your hands on 5 times more hashing power for just 2 hours, you stand a pretty good chance at rewinding a few blocks.

Here's my archive of the post: 55215120. TryNinja shows it was posted in Micro Earnings. I'm not sure if advertising altcoins is allowed on that board.

There's actually a way to check if your IP address and browser combo is going to give you a bad reCaptcha score without solving any captchas. Go to this reCaptcha v3 testing page https://recaptcha-demo.appspot.com/recaptcha-v3-request-scores.php, look for the line that says "score" and check the number next to it. The closer it is to 1, the more human it thinks you are.
I've checked it with 3 different connections, one of them through Tor, and I always get the exact same score:
Code:
"score": 0.9,
I don't think this is working properly.

"Donator" just means someone who donated 50btc
Actually, it's 10BTC:
If you donate 10 BTC, you can get a special "Donator" title and a green "who's online" color. If you donate 50 BTC, you get VIP status and the ability to create a custom title for yourself.
Without checking, I always thought Donator was more expensive than VIP.

I copy the link, go to the tor browser, paste and run and it takes me to the captcha page.
I just tested mine: it gets me a login page without captcha on Tor.

I dunno, despite having a commercial pilot's license, maybe I don't know what an airplane looks like  Huh
Captcha is almost impossible as a human on Tor nowadays.
13733  Other / Meta / Re: Suggestion: disable Press board & lock topics unattended by OPs in past months on: September 17, 2020, 06:23:26 PM
Do you think it would prevent the spam if the mods would close topics left unattended by the authors for long time?
I just report them when I see useless bumps after a long time.

I'm now on my regular browser to type this - it was impossible to visit here anonymously.
It can be done, but solving the captchas takes about 5 minutes to register, and another 5 minutes to login. After that you'll most likely have to pay an evil fee before your account can post anything.

But, once you're through, you can get a Captcha bypass code, and from this moment you can login without captcha on Tor.

There is a lot of discussion in the TOR community that captcha is puposely blocking sites that come from TOR IPs.
I've had that problem many times too. But I can imagine many Tor users are actually up to no good. I have no idea if Tor is often used by bots though.
13735  Economy / Games and rounds / Re: [Free Raffle] Win $25 in Ethereum on: September 17, 2020, 05:41:12 PM
but usually I saw threads like yours on Games and Rounds section.
On-forum altcoin giveaways (like this one) are not allowed. It can get OP and everyone who joined banned.
I tried to have this rule changed but as far as I know it's still in effect.

If you'd do the same with $25 in Bitcoin, it's totally fine in Games and rounds. If you pay in altcoins, you're not allowed to give people an incentive to post in the thread.



TL;DR Cool initiative, but risky Tongue

oh, look at my trading log with LoyceV.
I sent him 0.001 LTC. the transaction fee was 0.001 LTC  Grin
not to mention, I only have 0.001 LTC before from Mbitr. So I need to buy more LTC to cover the fee.
I just checked: Coinomi has a default fee of 0.001 LTC, so I can't even send it.

At the moment, there's not that much spam in Press: the oldest post on the first page was made on July 1. I didn't check for deleted topics, so it might be many recent spam has been removed already.

I like hilariousandco's idea to reject crypto-based news sites. Have a look at this list (not only for the Press board): it's no wonder a crypt-based site writes about crypto. It's news if it's the New York Times (this link is just a random example)!

You might ask LoyceV to scrape the data on the sections you mentioned and find out how many posts are reported and deleted from those sections.
Without scraping anything, I already know it's bad. Just have a look at Patrol, it's filled with "proof", "twitter" and "facebook" shitposts. The altcoin boards are also a lost cause: there are only a few topics that are worth reading, and most of those are flooded by spammers anyway.

I still don't get why it's allowed to post millions of mindless "bounty reports" on this forum.

After you've consolidated your Bitcoin to a new wallet, you own some Forkcoins too. Don't forget about them, but don't bother before moving your Bitcoin.
