I want to create a payment service where I want to be able to charge each client according to its invoice. I picked Electrum as my underlying wallet and pybitcontools as my Python interface.
I would like to assign for each invoice a separate address. However, using wallet GUI it requires a person doing so and would like to automate that. Sadly, I am unable to replicate the Electrum addresses and am a bit lost at what is going wrong
My current test code:
import bitcoin as btc electrum_master_public_key = 'xpub67xegn2C1yS...' for i in xrange( 5 ): print btc.pubkey_to_address( btc.bip32_descend( electrum_master_public_key, [0,i] ) )
All my generated addresses start with a 1 whereas Electrum’s star with 3. Would appreciate if somebody would help me to link the two.
I had this running perfectly and the blockchain was synching and at about 80% completion. I came home from work to a power outage.
I keep seeing to run bitcoin-qt, it doesn’t appear that I have that. In /src/ I have bitcoin-cli, bitcoind, and bitcoin-tx. Obviously d is daemon, and -tx isn’t what I want either. So I try
error: too few parameters (need at least command)
When a miner hashes a blocksheader and it produces a hash that is lower than the value represented by
nBits then the PoW is considered solved.
What exactly does this mean? For example a SHA256 hash has the following structure:
c45bc3de9bff9ee27fc7303a3aa4fa8022ab6608d42bbea4d72bbee9b719703b how do you determine whether this is below an
Where is stored a full data set of bitcoin blockchain?
../blocks/ dir contains a full data for blockchain work?
I know that
../chainstate/ and other files truly contains service information, include hashes, UTXO data set and others. But is it true that the full information already is in
A few years ago I mined a couple of alt-coins. Now I have approximately 5 wallets which are named in non-suggestive way:
wallet_05.dat. Each of them has reasonable amount of coins, also I have no idea how much exactly and what coin correspond to each wallet. Now I would like to restore some order by checking what do I have and how much.
Is there a way for me to figure this out? I do not remember exactly what these alt-coins are but have approximate ideas (probably can try to remember and select 30 potential candidates).
With this, I clearly can try each of the alt-coin client, wait for sync (may be do not even need this) and try to open each of the wallet. This will be very slow and because I am not 100% sure I will be lucky with my 30 crypto-coin guesses might take even longer.
So, is there a way to find a corresponding alt-coin for a wallet. Even maybe finding how much coins are in the wallet without downloading the client?
I recently followed the steps on the answer by StephenM347 to the following problem:
However, on the last step (broadcasting my transaction on https://live.blockcypher.com/btc-testnet/pushtx/) I got the error message:
Error validating transaction: Transaction eddxxxxxxxxxxxxxxxxx orphaned, missing reference 00350a8xxxxxxxxxxxxxx.
I am very new to this and all I want is to have my bitcoins on a MultiBit wallet (where I sent the Bitcoin Core bitcoins to).
Could anyone point me in the right direction here?
I am new to this bitcoin wallet use. I have funds allocated to Coinsquare but have yet to buy a single bitcoin or fraction of one. My question is,……. do I need a certain wallet for use in conjunction with a certain funding source? Will my Electrum wallet receive crypto currency from my Coinsquare account?
