Spurred by last month's SegWit activation, bitcoin developers are reviving a plan originally proposed in 2013 that would see the world's most popular …
Google Alert – bitcoin
For more privacy, suppose I am using a MPK to derive multiple one-time addresses that are in the same wallet (https://en.bitcoin.it/wiki/Address_reuse).
When I send funds from that wallet to Party B, won’t funds be drawn from multiple one-time addresses? And thus, Party B is able to see each individual who has paid to the one-time addresses.
So how do the one-time address help privacy?
Following a bitcoin core issue on
debian stretch which was resolved on the master branch, I am now running a pre-release test build. Each time I exit
bitcoin-qt, I have to wait about 5 minutes until final shutdown occurs. My debug file is showing:

This is where it hangs for a few minutes, then:

I have not experienced this before ever on any system. I am not seeing a similar issue when shutting down
bitcoind (EDIT actually it does happen with
bitcoind at times). I am wondering if anyone is aware of any pending change (on master branch for future release) which would explain such behavior (I worry this may be related to
debian stretch, but my hardware is new, very cheap and hopelessly slow on known benchmarks, which may also be the cause of this).
We can spend balance of an address if we have private key. is it true for master private key too? I mean, we could spend spend balance using master private key? or we should use child private key?
- what is difference between Master Public Key (MPK) and Public Key?
- what is difference between Master Private Key and Private Key?
- should I use master public key (MPK) when generating address or public key?
I have master public key of my wallet and I want to generate addresses but without using my current wallet. Is there a tool that does that?
Is there any posibilities to: 1. Create deterministic seed from 12 or 24 word 2. Create Private Master key from this deterministic seed 3. Create deterministic wallet using private master key
I’m goofing around with this fork of pybitcointools and I got stock with generating address for receiving coins with a master public key. So far, this is what I have:
import bitcoin as btc privatekey = btc.sha256("large example seed for this great test") print privatekey # 03e02b95a485112b543ac29cd262afbbd64dca9b4496e264e47312cb193ae5ab bip32_masterprivatekey = btc.bip32_master_key(privatekey) bip32_masterpublickey = btc.bip32_privtopub(bip32_masterprivatekey) print bip32_masterprivatekey # xprv9s21ZrQH143K3tQmGrVtKc7B6ZPtCJAmD6wDAJXxb7YXAoZFTb55UroSxrU7k823vSQmYPDhdseRKqP1mgSUWDneinai2seUd7RLX2xkmGW print bip32_masterpublickey # xpub661MyMwAqRbcGNVENt2tgk3uebENbktcaKroxgwa9T5W3btQ18PL2f7vp78LNoioGhZcgSH1i2cH48YcQttiEaAh86TuJpsUu2J7jQWnmbC
