Here I would like to generate the other address using xpub.
Is there a library (python) that can help derive the new address from an extended key?
gen_new_pub (xpub, new_path) to get the public key derived.
Of course, the library assumes that it could support
gen_new_prv (xprv, new_path) to generate the corresponding private key according to xprv and the path.
I do not understand the differences between
get new address
For example, I have a local blockchain (regtest) with 0 Block.
I believe 101 block (
I can see with
listddressgroupings this exit
[ [ [ "mvAH7VsxifvQdEZ46Rdt2oN3nB5BzaPqS8", 50.00000000 ] ]]
What address is
If you dump the private key
I have this result
ok, if I look for this private key in
dumpwallet test.txt That key associated with this address.
MVA_PRIVATEKEY 2019-01-19T10: 26: 19Z change = 1 # addr = 2NAoHv7kDBhHND7YHcQKuDS8wCbEz87xLrv hdkeypath = m / 0 & # 39; / 0 & # 39; / 0 & # 39; / 0 & # 39;
Because it is not
Now I want to create a new address getnewaddress =>
Why does this address begin with 2 and not with m or n? Your pk is different from
If I create another block 101, I have a new address in
Every time I create a new block, I have a new address in
I'm getting an error of electrum 3.3.2 with something to do with dust.
the transaction was rejected by the dust network error rules
I'm using the cli to send a transaction and I'm only using 1 entry and 1 exit only. And the rate is established automatically. Yesterday was working well. I read that it is something to do with the node. But what's wrong with that? I tried many other public nodes and said the same error. What's going on? An attack?
What solutions are there for something like this? My application depends on having electrum working at all times.

Reddit could not help me https://www.reddit.com/r/BitcoinBeginners/comments/aftb91/am_i_running_bitcoin_core/
This is not a problem of permission.

I suspect that the
bitcoind -server that runs in isolation, since "nobody" is trying to access my home directory, which is a bit worrisome. My user's .bitcoin directory looks good:

I started installing bitcoin nodes, created by the same people as the bitcoin kernel. I realized that I do not have enough space on my computer. I also forgot my password phrase. If someone trusted here has already installed Bitcoin Knots or Bitcoin-Qt, I will give them half of my wallet to recover my bitcoin (approximately 0.0032).
Is it possible to create wallet url services for bitcoin core wallet?
I send 2.48 btc to this aggregate in the Copay portfolio.
But now, I can see in Copay.
Copay say: network error.
The zero confirmation transactions can be easily spent twice with another signed transaction that spends the same UTXO, but with an arbitrarily higher rate, thus achieving a higher probability of being extracted first, making the original transaction invalid.
A merchant still needs a complete node to accept new transactions in the memory group, since it needs to validate each new transaction it sees.
A light wallet does not have the same security as a complete node, because it is based on the verification of the accumulated POW and not on the actual validity of the transaction. The assumption is that the chain with the most accumulated POW must be valid.
A friend suggested that I use Jaxx Wallet, so I downloaded the software and sent my BTC using its Coinbase QR code. Looking back, I should have left it where it was!
Never arrived. I also sent LTC using the same QR code method. That has arrived and it's in my Jaxx wallet now.
I see my transaction completed and verified in the blockchain. How do I locate where it is?
How can I trace that this transaction was actually sent (and maybe received) by Jaxx even though it does not show up in my wallet?
