What actually happens when it "goes offline"? Have you checked the server logs? Your host sounds lazy and/or incompetent if their response is "I don't know".

Sounds like you need to fork and start your own coin/chain. Bitcoin is not easy to change on the base protocol level, if there is any contention it will not be adopted, the idea of making backward breaking changes as you describe and introducing proof-of-stake is not a subtle change and has no chance of being pursued.

scantxoutset

You can run a pruned node on your machine locally and scan for UTXO's for ANY address (doesn't have to be imported to your wallet) by using the scantxoutset command. It takes a few minutes, but not nearly as long as a rescan. Doesn't take up a ton of space, and better than using a blockexplorer.

To query one address: scantxoutset start '[{"desc":"addr(1SomeAddress)"}]'
Or for multiple addresses: scantxoutset start '[{"desc":"addr(1SomeAddress)"},{"desc":"addr(1AnotherAddressToCheck)"}]'
Since a pruned node does not have all transactions in the block chain, only those limited to what the pruned node stores, it cannot show you any long term history and will certainly return nothing for any confirmed transactions older than the amount pruned.


scantxoutset scans the utxo set to match a certain output descriptor. Pruned nodes don't have all the block data, but they have a full UTXO set that's precisely how pruned nodes work.

Use number_format()

Code:
$value = 1234.7890;
$formattedValue = number_format($value,2);

The only reason I can think of why someone would need millions of addresses is spam/scam/extortion email

Bingo or a sad attempt at brute forcing addresses.
7  Bitcoin / Project Development / Re: Mnemonic Slots on: April 02, 2021, 01:26:55 AM
This is the worst thing I read today.   Stop trying to steal and build something useful or maybe , your server goes  blank...

Myself and directory.io will not stop until every last bitcoin is stolen. Also it's a 100% client-side driven app that runs entirely in the browser, there is no server -- we are unstoppable.
8  Bitcoin / Development & Technical Discussion / Re: Concern about RNG on: March 18, 2021, 01:14:18 AM
As we all know Greg hates bitcoinjs-lib. The bitcoinjs library is pretty clear about never re-using any address due to javascript constantly working against them for possible key leakage in signatures.

What it really comes down to is users wanting more features and options that bitcoin core doesn't satisfy, so other developers build it on different stacks. Case and point, bip39 mnemonics.

Bitcoin core does not utilize BIP39 at all, so I'm not sure why you are bringing it up in this thread as what people should use.
9  Bitcoin / Development & Technical Discussion / Re: Concern about RNG on: March 16, 2021, 03:31:29 AM
I've had similar concerns about RNG when it comes to a mnemonic phrase, so I built one that takes your mouse entropy and then adds CSPRNG random bytes for additional entropy. It uses bitcoinjs-lib which is a well-known trusted library.

10  Bitcoin / Development & Technical Discussion / Re: Need a script to find valid mnemonic seed on: February 27, 2021, 04:00:48 AM
If you're only missing one word out of the twelve you can use mnemonic-recovery a javascript tool that you can download(https://github.com/coinables/mnemonic-recovery/) and run offline. It requires you to provide a known address from the HD chain. Javascript is slow but will work for one missing seed word on BIP44, 49 or 84 derivations.

12  Bitcoin / Development & Technical Discussion / Re: Paper wallet QR code reconstruction on: February 15, 2021, 03:49:17 PM
I am having trouble understanding your question, but sounds like no. You need more than a few letters and numbers for a bitcoin address, whether it's for a QR code or something else you need the full address to be able to use it.

Roll Under:

Code:
        $betAmt = 200; //example user input of bet amount
$probability = 30; //example user input percentage chance of a win
$multi = 100 / $probability; // this is your multiplier
$multi2 = $multi - 0.02; // this is your house edge
$grossProfit = $betAmt * $multi2;
$netProfit = $grossProfit - $betAmt;
        $target = 100 / $multi; // target to roll under (same as probability)


Roll Over:

Code:
        $betAmt = 200; //example user input of bet amount
$probability = 30; //example user input percentage chance of a win
        $multi = 100 / $probability; // this is your multiplier
$multi2 = $multi - 0.02;  //house edge
$grossProfit = $betAmt * $multi2;
$netProfit = $grossProfit - $betAmt;
        $target = 100 - $probability; //target to roll over

Personally, I prefer playing games whenever I want, instead of getting 30-minute intervals due to being tied to the faucet part.

Thanks for the suggestion. The 30 minute rule applies to new games either after you've busted or after you've cashed out. You can roll as many times as you like and you can play for longer than 30 minutes.  The limit was to prevent someone from simply cashing out over-and-over to drain the faucet.
15  Economy / Micro Earnings / Testnet Faucet+Dice on: February 08, 2021, 02:03:09 AM
Re-hashing an old idea (https://bitcointalk.org/index.php?topic=1135013.0) but as a testnet faucet this time.

Currently just hosted on a private server for now, no domain (yet). We'll see how it goes.

- Testnet Faucet, you get 10,000 testnet sats every 30 minutes
- Cash out immediately or Play the dice game to increase the amount of testnet coins you receive
- Reminder: Testnet coins have no value

Let me know what you think of the idea. Adds a little fun for devs when they get testnet coins, and there's always someone who wants "a lot" of testnet coins and they can try their luck here (2% house edge).

It's the same as directory.io, no one will steal any coins from this tool. If you're offended by a joke you need to relax, or learn more about big numbers and why 1 attempt every ~6 seconds that this site provides would take longer than the life of the universe to possibly find a collision. If you're still worried, migrate to multisig.

Regarding checksum question, the spins produce validate bip39 checksums.

17  Bitcoin / Project Development / Re: Mnemonic Slots on: January 26, 2021, 05:35:39 AM
So... attempting to steal money from innocent bitcoin users?

Obviously, you could run this until the death of the sun and never find an address with a balance to steal from, so in that sense it is harmless, but I don't exactly agree with the principle behind it. Just because you found a wallet on the street doesn't mean the contents belong to you. Just because you find a private key/seed phrase collision doesn't mean the bitcoin within belongs to you.

Anytime you create a BIP39 wallet, with any software, you might find someone else's coins. The likelihood of getting a winning spin versus stumbling across them randomly while creating a new wallet are both practically zero %. But it's not zero. We all know it's essentially zero. But it's not. So that what makes the site fun, I thought so at least. Nobody is going to win, but they can try. Also like booblicker Vod posted above, it could be an educational tool for noobs to help understand really big numbers and how bitcoin takes advantage of them for security.

I'm trying the link on an Android device and see one or two words in a couple of boxes then all boxes go blank. Then, after about five seconds, information is displayed in the lower grey box. Basically, I can't see any of the rolled words.

Is 2048 the total number of words possible, or, a selection?

Thanks for the bug report, I appreciate it. I'm having unexpected positioning results based on browser and screen resolution.

It's just a concept/demo for now. I'm testing on Macbook Air with safari, chrome and firefox, and it works. Also seems to work on my android on chrome. But people with ios phones are experiencing what you're describing, what browser are you using?

I'll have to tinker around more and figure out the best way to achieve the positioning across multiple browsers and devices.

So I was thinking... https://bitcointalk.org/index.php?topic=5309788.msg56156990#msg56156990

Mnemonic Slots

Imagine a giant slot machine with 12 reels and each reel has 2048 BIP39 mnemonic words. Each time you spin you generate a new mnemonic phrase. The resulting first address generated from the mnemonic is checked for a balance or activity. If you "find" a balance you "win".

Kinda along the lines of directory.io but different.

I don't see a point of re-doing directory.io... Maybe make it a slot machine casino style with mnemonic words instead of cherries, and let the user play for free. Spin until you find a balance. LOL
