Bitcointalk Quotes

[The Sceptical Chymist]

I need to find a way for users to humbly select their own posts. It'll speed up the process.

All a matter of incentives.  

Hmm.  I'm not sure every member would suggest their own posts humbly at all.  In fact, it could quickly turn into a spam fest on your end if you've got to approve them all--and if you aren't approving them, we'll probably end up seeing a bunch of meaningless, low-value quotes by members with egos far bigger than their forum contributions.

Know what I mean?  Aside from that I still like the site very much!

I generated 5 blocks today on my Pentium processor.

Oh man, to have been aware of, and involved in, bitcoin way back then.  If only I had a private time machine...

[LoyceV]

The site works on Tor now. Nice

I generated 5 blocks today on my Pentium processor.

Oh man, to have been aware of, and involved in, bitcoin way back then.

I feel your pain of "what if". But I also know I would probably have ended up like this:

I actually measured the energy usage with a Kill-A-Watt with and without mining a few months after that post, and I was getting 160 BTC/kWh. Because the cost of mining 1 BTC was less than a tenth of what 1 BTC was actually priced at at the time, I thought that BTC was substantially overpriced, and so I also have the honor of selling BTC at the lowest prices ever recorded, $0.003/BTC.

Ha-ha, thanks for the tBTC!  

Which program did you use to convert the mainnet Segwit to testnet4 Segwit? It should be fairly easy, but I'm not aware of any, so it must have been done manually. First time another person constructs my own address.  

Oh man, to have been aware of, and involved in, bitcoin way back then.  If only I had a private time machine...

I can tell the same thing for 2015, which is when you registered. And someone else will say the same thing about me in a few years from now. We should never forget to appreciate what we have in life.

Which program did you use to convert the mainnet Segwit to testnet4 Segwit?

Bitcoin Core. By the way: you don't need to "convert" anything, you can instead create a transaction, sending coins to the mainnet address, and then sign that transaction under testnet. Also, if you want to move those coins, then again: you can create a transaction under testnet, and sign it from your mainnet node. In this way, no conversions are needed.

Another benefit of doing that, is testing offline signing, which is a good habit in general.

Edit: Let's make it a double:

Code:

createrawtransaction '[{"txid":"1e5c0c5c2e71f2adb7804d4a1f9e2d4d22e500bde8330573e11774be9871e05d","vout":0}]' '[{"bc1qmx0qn8rak9zpftl27ryr5en6ffsvhex37kuta0":50.00000000}]' 0 true
02000000015de07198be7417e1730533e8bd00e5224d2d9e1f4a4d80b7adf2712e5c0c5c1e0000000000fdffffff0100f2052a01000000160014d99e099c7db14414afeaf0c83a667a4a60cbe4d100000000

And then, if you did that from your mainnet node, and you have well-formed transaction, then you can sign it under testnet:

Code:

signrawtransactionwithwallet "02000000015de07198be7417e1730533e8bd00e5224d2d9e1f4a4d80b7adf2712e5c0c5c1e0000000000fdffffff0100f2052a01000000160014d99e099c7db14414afeaf0c83a667a4a60cbe4d100000000" '[{"txid":"1e5c0c5c2e71f2adb7804d4a1f9e2d4d22e500bde8330573e11774be9871e05d","vout":0,"scriptPubKey":"0014bf333b43b2416a9cde98666f169e0e7c111f509d","amount":50.00001559}]'
{
  "hex": "020000000001015de07198be7417e1730533e8bd00e5224d2d9e1f4a4d80b7adf2712e5c0c5c1e0000000000fdffffff0100f2052a01000000160014d99e099c7db14414afeaf0c83a667a4a60cbe4d1024730440220514d1e998eb8c9681918dce33649eef5da838c8f70631c75b92175ebbd3c7afc022045a9ff34384c9dcc1584975d7476c0634105e5533103c08cb2f09e54ba9b1c33012103acfb93083094546a7f7dccf231f506bed26711e06e7806427ec68dd3a12940e300000000",
  "complete": true
}

Then, all that is left, is to just send this transaction, using any tool: your own node, some block explorer, whatever:

Code:

$ ./bitcoin-cli -testnet4 sendrawtransaction 020000000001015de07198be7417e1730533e8bd00e5224d2d9e1f4a4d80b7adf2712e5c0c5c1e0000000000fdffffff0100f2052a01000000160014d99e099c7db14414afeaf0c83a667a4a60cbe4d1024730440220514d1e998eb8c9681918dce33649eef5da838c8f70631c75b92175ebbd3c7afc022045a9ff34384c9dcc1584975d7476c0634105e5533103c08cb2f09e54ba9b1c33012103acfb93083094546a7f7dccf231f506bed26711e06e7806427ec68dd3a12940e300000000

Bitcoin Core is such a cool software. LoyceV, sent you a testnet bitcoin, in case you ever need one: f54ec488b37dbd0dc948572fb866f870fbf82a0c7e3813c3d4c61d7dfd442946.

[ercewubam]

Bitcoin Core is such a cool software.

It indeed is. Also note, that testnet4 is still in its infancy. So, you can get your transaction confirmed even for free, as long as there is enough space in blocks. You can check your peers, maybe some of them accept free transactions?

Code:

$ ./bitcoin-cli -testnet4 getpeerinfo | grep minfeefilter
"minfeefilter": 0.00000000,
"minfeefilter": 0.00000000,
"minfeefilter": 0.00001000,
"minfeefilter": 0.00001000,
"minfeefilter": 0.00001000,
"minfeefilter": 0.00001000,
"minfeefilter": 0.00001000,
"minfeefilter": 0.00001000,
"minfeefilter": 0.00001000,
"minfeefilter": 0.00001000,

So, if you spot a node with "minfeefilter" set to zero (or anything lower than 0.00001000), then you can try to send a cheaper (or free) transaction, and there is a chance, that you are connected to some CPU miner, who will confirm it for free.

For example, for testnet4, I have these settings:

Code:

mintxfee=0.00000001
minrelaytxfee=0.00000000
blockmintxfee=0.00000000
dustrelayfee=0.00000000
mempoolexpiry=35000
acceptnonstdtxn=1
maxtxfee=1000000.00000000
mempoolfullrbf=1

Let's see, if you can correctly sweep coinbase transaction: https://mempool.space/testnet4/tx/296c14acfc4aa71a53d1d2e0fda8c3702aaeab20fa7fea78c185a4fd4972bddc

Because a lot of people cannot do that, for some reason. Maybe they use "getreceivedbyaddress" or something.

Lol. It's kinda cool, having some testnet4 coins could come in handy some day. Is that the address in my profile? I don't really want to search all my existing addresses, but if that's the one, I'll keep it separately

So you mined testnet4 to BlackHatCoiner's Bitcoin address? Lol
Isn't spending them as easy as importing the private key in Bitcoin Core (on testnet4 of course)?

[ercewubam]

So you mined testnet4 to BlackHatCoiner's Bitcoin address?

Check closer, who is the owner of this address: https://mempool.space/testnet4/address/tb1qy65a0ltkaxpuwc22gx2zjehac8gpgppawrmpud

Isn't spending them as easy as importing the private key in Bitcoin Core (on testnet4 of course)?

It is, but:
1. Some parties, like exchanges, often don't process them correctly, and don't associate those coins with your account.
2. You have to wait for coinbase maturity (100 blocks).

I was hoping getting testnet4 working would be easier by now, but I'm still stuck on boost errors. I guess I'll just wait until testnet4 is enabled by default. For now, I've labeled the address as "testnet4"

I get the exact same result as you do, but nodes reject my 0 sat/vb transaction:

Yep, it's the bech32 one, sitting on your profile page.

I was facing some problems too when I tried to do this manually, but all it needed was just to fetch the clone properly. Did you fetch it as written in here?

[LoyceV]

Did you fetch it as written in here?

Yep. I could spin up a spare laptop, install a standard Ubuntu version, and try again, but it's easier to just wait for testnet3 to be shredded and replaced by the new version by default Maybe when I have more time

[garlonicon]

but nodes reject my 0 sat/vb transaction

Other nodes won't accept it, if your own node will reject it. You have to configure your node first, to accept those transactions locally.

but I'm still stuck on boost errors

What about GitHub pipelines? For example, I am trying to build my changes there: https://github.com/garlonicon/bitcoin/actions/runs/10558037449

I guess, if it will be successful, then you could simply download binaries from there. Because if things are built on GitHub, then you can see, that I didn't touch them at all, and you can read all code changes in a pull request to see, if they are correct or not.

Also note, that because I changed those things globally, I don't recommend using those binaries to run a mainnet node (because then, it may try to produce blocks with 20 minute delay, for no reason).

[DubemIfedigbo001]

These are some golden words, but they are casually presented, could you add some CSS to the page to beautify it, increase the font size a bit and use a better font for its presentation, also add a few quotes to the view at once so we can read more than one in a page and introduce pagination to see more of it when desired. Also could you introduce a select button with names of those who have the quotes so we can select which person's quotes to read at a time.

If you strictly want it to be one read a time
Better still, you can fetch the quotes and save it on an array as soon as the page loads, then manage the Random display from the array, so the page does not need to refresh before the user gets another random quote, it can improve the experience and desire of the reader to consume more of your contents.

You could avoid repetition of the same quote by removing it from the array, then randomly display others until the array is empty, also use  an indicator to tell the user how many quotes they have read, and how many more to go. kind of keeps the user engaged.

Nice work though

[BlackHatCoiner]

Other nodes won't accept it, if your own node will reject it. You have to configure your node first, to accept those transactions locally.

I just opened Bitcoin Core after the last time I posted. Transaction is confirmed, even though I checked it hadn't reached mempool.space's node, at the time I sent it. Isn't that strange? My node's configuration is default, probably rejecting anything lower than 1 sat/vb. I have no configuration file, and start Core with ./bitcoin-qt --testnet4. The only reasonable explanation is that some of you broadcasted it for me.
