Topic: Has anyone put unmined blocks on the blockchain network? (Read 236 times)

I will be glad to help you but you have not shared your contact or communication channel if you want please get in touch with me. Search on google "Technoloader". 

This sounds like a very insecure way to generate a seed phrase.

Is this a wallet.dat file? The data looks encrypted, so you will need to remember or brute force the decryption key.

There is no common private key format which is 45 characters long, so no, blockchain.com will not accept this. Are you sure what you have is a private key? What character set does it use?

i use a sha256 to generate the seed phrase but 64 characters is not long enough, so i x2 or x3 it
I also dump the private key and wrote it down, but it was lost, only sha256 characters left is seed pharse
i'm try edit file with notepad, this is image https://i.ibb.co/JKfS8VM/whatwallet.jpg

i also have one more question, does blockchain.com use 45 character, i know can use 44,51.52,64 ...
and how can i convert from this 45 character to wif

No. Bitcoin Core has never used a seed phrase.

You probably had a different wallet, for instance Electrum. Depending of the seed phrase you have there might be different options to restore your wallet.

I have an off-topic question
can you help me how to recover a bitcoincore wallet with seed pharse ? I can't download an old version, and I don't know if it's possible to restore
I think it's the 2015 version support create a seed phrase for new wallet
thank's



Thank you for reminding, I will continue with other work

I prefer "for information" conversations public so other users can use it for reference and also to minimize duplicated topics.

No, but blocks aren't something you can pre-generate then put in the blockchain days later.

It's called "block" + "chain" for a reason,
because the next block should be built on top of the latest block since the previous block's "hashPrevBlock" should be included to the next block's block header (so on, so forth); that connects the chain.
If you somehow managed to build a valid block now, but haven't broadcast it right away, then it wont be valid after its height was occupied by another miner's block.
Not to mention, the validity of the transactions in it.

BTW, you should specify the steps that you've done to build a block.

What exactly do you want:
1) that the transactions of your "unmined block" go through?
2) get the block reward with the "help" of a miner?

1) would be easy: like nc50lc wrote, you'll have to ensure the transaction fees are all above the current threshold to be mined. If you have 1 vMB (the number of transactions is not important, what's important is the weight) of transactions, then you'll in the last hours had to pay 0.02 to 0.08 BTC (between 2 and 8 sat/vByte), because currently the fees are cheap.

2), which is what I guess you want to do, is something normally should be discouraged by the Bitcoin protocol, as it could allow an attack. But it's also interesting to discuss it:

Let's say you prepare the block. You include a transaction with a generous fee which is significantly more than what a miner currently can expect currently for a mined block. The coinbase transaction goes to you instead of the miner (I'm not 100% sure if this is possible, but otherwise you could agree with the miner about a transaction to you which shares the block reward). So you're "sharing" the coinbase reward with the miner.

But, regardless of how you do the math, it will never pay off for you. The transaction fee you'll have to pay will always be larger of what you'll receive as reward.

The only case I can imagine where there "could" be a profit for you, is if you find some friends who need transactions to be mined urgently and would then also be willing to pay a higher-than-normal fee. You would then bundle a group of high-fee transactions together and "offer" them privately to a miner. However, this has also a problem: you must trust the miner, as he could simply take the transactions and include them into his own block which doesn't give you the reward. (Of course, he can also do the same thing with the transaction with the generous fee you sent to him.)

So as far as I understand, if 2) is really what you want, it makes no sense at all.

how to talk direct to you ?
I want more information about this and i use this article for a different reason
do you mean blocks can be mined from 1 miner?
but I just have some blocks waited when I had time and i want to try

Did you mean you have unmined unconfirmed transactions?

Then you would have to pay miners with amount greater than the reward that they usually receive from their mined blocks.
You're basically asking a miner to mine "your block" which is technically theirs since they will do the proof-of-work.

Here are the miners: http://bitcointalk.org/index.php?board=14.0 | Go to "pool" sub-board.

how can i talk to you directly, do you use telegram or icq?

What do you mean by putting an unmined block on the blockchain?
Do you mean you have found a block and now you want to broadcast it to the network?

What's the point of broadcasting blocks that have been mined before?
It's not that you can mine a block now and broadcast it at any time you want.
The block reward goes to the miner who solves the proof of work problem faster than others. So, your block won't be accepted by other nodes and there will be no reward for you.

i have some unmined block and need someone help to mine it, put it on blockchain network,
I have read and researched at learmeabitcoin.com but maybe I still need someone who can help
