Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN][XCP] Counterparty - Pioneering Peer-to-Peer Finance - Official Thread

10 users replied, which is nice to see! Goodies will be sent in the next couple of days. If we manage to get 15 responses, a never-used, 9-year-old 4-letter pronounceable asset will be given out too.

In the mood to send some free Counterparty goodies to old-timers who were already around more than 5 years ago... Post or PM addresses! (Will send after getting at least 7-8 responses)

Anyone looking to sell their XCP bags for BTC, DM me, if the price is right I will buy in bulk (500 and more).

Bitcoin / Electrum / Advanced: cancel (double-spend) a non-electrum transaction?

on: January 22, 2025, 10:23:19 PM

Is there a way to use Electrum to double-spend a transaction that is not RBF enabled? The transaction was made by another wallet that has no RBF support. I've imported the relevant private key into Electrum and see the pending transaction, but is there a trick for me to cancel it even though I don't have the right-click menu option available due to the absence of the RBF flag?

"Windows is extremely easy to break into" This is common misconception, unfortunately. You may be thinking of Windows XP or another ancient version? These days running an updated version of Windows (as millions of users are) is safe. Of course you also need to use sound security practices, which is just as true with Linux.

So, who is still around, more than 10 years after launch? Anyone from the old days who reponds to this post, I've got plenty of goodies (some high-issuance pepes, some rarer ones, some fun old assets) to give away! To qualify: you must have previously posted in this thread prior to July 2019 _and_ you must not have posted anything more recently. Either post your Counterparty address here, or by PM.

Quote from: LoyceV on March 10, 2024, 09:38:46 AM Quote from: RoxxR on March 10, 2024, 09:29:24 AM Just noticed this today. I got 2 extremely similar private keys. Does anyone know if this could be a sign of a security issue with the PRNG? Probably not Yes! This should not happen. Unless you altered the source to search from a specific starting point. I've never used VanitySearch (because I hardly trust any new software), and I don't know how it works internally, but I would expect it to generate a new random private key after finding a match. I think it's okay to add "+1" from a random number to search the next one (which I expect to be much faster than generating new private keys all the time), but two similar private keys shouldn't happen. I'm just using the official build, unaltered. (OS: Windows 10 with the latest security updates) Just found another 2 even more similar private keys: 0x90AD2D51198584C695F79D27512B147C865C7093E10065F4B4363881C882C87D 0x90AD2D51198584C695F79D27512B147C865C7093E10065F2B4363881C87CF970 PubAddress: bc1q22ace8n7qwe3xtazp05x6vl8fy7mkf5cwznnp5 Priv (WIF): p2wpkh:L24wedqSrZsKNmmF33fxZj75Xz4P4K562VzHKJCE4Q2p6TrBoJha Priv (HEX): 0x90AD2D51198584C695F79D27512B147C865C7093E10065F2B4363881C87CF970 PubAddress: bc1q22acevaq6x6r4867ay2n73qfgjlcj95pzrxx9x Priv (WIF): p2wpkh:L24wedqSrZsKNmmF33fxZj75Xz4P4K562WivkuVB3vnYXXDimUkL Priv (HEX): 0x90AD2D51198584C695F79D27512B147C865C7093E10065F4B4363881C882C87D At this point I'm guessing this is due to performance optimizations made by the developer?

So I've lost my 12-word seed but I still know the first letter of each word. Can I make a script trying all possible combinations and recover my seed in a reasonable amount of time?

A general question, what is the best way to proceed without getting scammed, when person A has the password and person B has the wallet file ? Any suggestions?

on: February 19, 2023, 06:01:21 AM

Quote from: pooya87 on February 19, 2023, 03:23:22 AM Here is another fun way of doing it which is a lot faster and cheaper to do: If you run a SPV client like Electrum on your computer you already have all the block headers saved up in a ~60 MB file called "blockchain_headers" which is a stream of bytes. All you have to do is to programatically read this file to get the raw bytes which should be a multiple of 80. Each 80 byte is a block header of a block in chronological order (so you have the block height this way too). Then start from the beginning (byte 0) and extract the time from each 80 byte chunk (ie. one header) knowing that 4th item in it is the timestamp. Code: version[4] + prev_hash[32] + merkle_root[32] + time[4] + target[4] + nonce[4] Here is a pseudocode Code: stream = File.Read("blockchain_headers") while(stream.HasBytesLeft) stream.Skip(68) timestamp = stream.Read(4).ConvertToTime_LittleEndian() resultList.Add(timestamp) stream.Skip(8) Now all you have to do is search in the list of timestamps to see when the day in the datetime you converted changes to get the last height of the day. The height is the index of the datetime inside the resultList/array. Keep in mind that timestamps are in UTC not your local time. Thanks, this does sound like a fun and effective way. I'll give it a shot!

on: February 18, 2023, 12:40:21 PM

I'm trying to programmatically get the block height at certain given dates - for instance, first day of each month. I don't have access to a full node. Is there a block explorer or other platform with an API endpoint (or just a small dump of such data somewhere) that could be helpful? Thanks!

on: October 19, 2022, 01:21:01 PM

I've just seen the below tx go through with a 191 sat fee. I don't remember seeing such a low fee in a confirmed transaction lately. https://mempool.space/tx/507402f95a07511bb8ba3d5fecfa65bb1d9e44367aef42d38cfa8238c243f54b Anyone aware of lower fee examples (in 2022)? EDIT: I assume fees can be even lower with segwit, right?
