hd wallet – Bitcoin Core 0.17 sethdseed dumpwallet how to recalculate the extended private master key?

  • Using bitcoin-cli -datadir = X sethdseed true "WIF_KEY" The current wallet within datadir is updated
  • Then, using bitcoin-cli -datadir = X dumpwallet my_dump.txt shows a new and fresh
    # masterkey private extended: tpriv …, which is generated determinisamente from the WIF_KEY

Now, using the # private masterkey extended In fact, it could generate the same address as the bitcoin kernel with the m / 0 & # 39; / 0 & # 39; / i & # 39; derivative route.

How could I calculate the # private masterkey extended Without throwing away the wallet, using tools like libbitcoin bx ?

In addition, the dumping file shows a
WIF_KEY 2019-03-22T14: 43: 55Z hdseed = 1 # addr = mnMEP6P92XKxKfEM5v2SxzLBMVB2tf7Lsj hdkeypath = s
which is exactly the m / 44 & # 39; / 1 & # 39; / 0 & # 39; / 0/0 from the WIF_KEY approved in sethdseed cmd why

hd wallet – Bitcoin Core change derivation path with getnewaddress cmd 0.17

As I am building a simple HD wallet, I would like to use bitcoin core regtest. My goal is to set up a test flow where I can have a constant initial address every time I use bitcoin-testnet-box, so that I could verify the derived addresses among other tests.

Using bitcoin-cli sethdseed Y get new address is the way, but I can not find a solution to derive secondary keys using another route than the bitcoin default which seems to be m / 0 & # 39; / 0 & # 39; / i & # 39;.

Is there a way to change the derivation route in a personalized way?

The sendtoaddress command does not work with bech32 bitcoin core 0.17

I have bitcoin-core 0.17 working in regtest Mode and when I try to send a test32 address to bech32 I get an invalid address

I have put addresstype = bech32 in my bitcoin.conf

hd wallet – Is the hdSeedid in Bitcoin Core 0.17 RPC the seed itself?

I am trying to find the seed for the HD wallet in version 0.17 of Bitcoin Core. I used the getwalletinfo command in the RPC console that produced information that includes a string that calls hdseedid, which is curiously the same as the string called hdmasterkeyid.

My question is: is that chain the actual seed of real hd and, if not, how will I find it or show it?

Any clarifications appreciated.
