Hello,

Thanks for everybody inputs. I'm aware that i'm not going to be rich easily with staking but my aim is to have a better
understanding of the concept. I like learning:)
ETH is my favorite alt, but i don't mind staking others. Btw, why rewards differ greatly on alt? Indeed, i never seen
a decent reward with BTC staking...

Software and navigator plugins seem indeed easy to use and might be the best solution to start earning,
but they are "black" boxes to me. Ten years ago, i enjoyed mining BTC with a RaspberryPi 1 and 4 USB
asic miners...Those were the days:)


I have a few questions. Would i have to download the whole blockchain to do solo staking? Also, why leasing to pool is
different from non custodial staking like blacknet? And more generally i would be interested to better understand the differences of these four concepts (non custodial staking, solo staking, leasing to pool and operating pool...

Thanks a lot:)

Hello everyone,

I heard that it is possible to stake with my own wallet.
This seems to provide you the best of two worlds: you
keep control of your funds and you earn rewards with
them. That being said, the only info i can get on this
is: "Non-custodial staking is more complicated and requires
technical skills and blockchain knowledge that is beyond
most beginners".

Can someone elaborate or give a link for a better
understanding?

Thanks a lot:)

Ok, i still need to have a better understanding of this (for my knowledge). Indeed, for me a random number from a computer is always pseudo-random. I found a link that might help me:
https://docs.python.org/3.8/library/secrets.html

It seems to do the job as i get a 12 words list...

I don't think they did it on purpose, but i agree it is unacceptable. Also, their customer details has been hacked...

The link is very interesting indeed. Here is a script:
import random
from datetime import datetime
random.seed(datetime.now().timestamp())
T=[]
for i in range(127):
        x=random.random()
        if x<0.5:
              T.append(0)
        else:
              T.append(1)
print(T)

Not sure if it is better than the previous method though...

The Python code is extremely simple and since it is from:
https://github.com/trezor/python-mnemonic
i assumed (wrongly?) that it is the way Trezor wallets generate their Bip39 mnemonic:
>>>from mnemonic import Mnemonic
>>>mnemo = Mnemonic("english")
>>>words = mnemo.generate(strength=128)
>>>print(words)

Is it safe to use?

Thanks:)

Ok, thanks for the answers. So, to sum-up here is my plan:

1) Generate (and carefully save) a BIP39 mnemonic code (offline) using this:
https://github.com/trezor/python-mnemonic
Indeed, Electrum wallet doesn't generate Bip39 mnemonic and i would prefer
to have one.
I tested the few lines of code and it worked.
Still there is something i don't understand:
entropy = mnemo.to_entropy(words)
I guess the aim of this line is to check the randomness of the list of words.
However, i got this:
>>> entropy = mnemo.to_entropy(words)
>>> entropy
bytearray(b'\x18\xe2\xa9=\x82\xd4$\x915D\x98....................................\xb4\x7f\x02\x90f\xdf\x8b')
>>>
How this should be understood?

P.S.: I read that a 12 words list is enough and a 24 words list do not improve safety. So i will
go for a 12 words list.

2) Create a new (offline) wallet by importing the mnemonic into Electrum. Generate a "receiving" address

3) Send the BTC from the exchanges to this address.

Am i doing something wrong?

Cheers:)

I agree, but it could be stressful. My aim is to choose the easiest and the safest solution to store BTC. Btw, is it possible to convert a Bip39 seed phrase into an Electrum seed and vice versa?

Cheers:)

I hope so too...


But, in that case you should know which derivation path the software used in order to recover the address where the funds are located, aren't you?

Hello everyone:)

I own some BTC that are stored ATM in an exchange (yes, i know it is bad....).
I would like to store them offline for the very very long term. My aim would be to
create a brand new wallet, with for instance Electrum, and move the funds
into it. Since the Electrum Software would be installed on a Ubuntu live session,
i only plan to carefully write the seed on a piece of paper (or better engrave
the seed on steel) before leaving. That being said, i noticed that Electrum
said that BIP39 seed might no longer be supported in the future, and, one the other hand, if i
create an Electrum seed it might not be accepted on other devices. Since my
aim is obviously to have access to my BTC later, i'm puzzled. How can i predidict the
standards in ten years?

Perhaps saving the master private key as a QR code might be a better idea...

I know that a ledger wallet might be better, but i read that the code source is not
open and i'm concerned about the data that might be collected by them (who knows
if they don't keep information about all the transactions of their users).

Any though?

Thanks a lot.

Might not work in the future:
"BIP39 seeds do not include a version number, which compromises compatibility with future software. We do not guarantee that BIP39 imports will always be supported in Electrum."

Here are the modifications i made:

I changed:

import bip_utils

instead of

import bip32utils

and

root_key = bip_utils.BIP84Key.fromEntropy(seed)

instead of

root_key = bip32utils.BIP32Key.fromEntropy(seed)

but that doesn't work: AttributeError: module 'bip_utils' has no attribute 'BIP84Key'

Any ideas? Thanks a lot, i appreciate your help:)

Yes, indeed. And now i know that it is a SegWit HD wallets. I have to modify the script above...

Thanks.

First of all, thanks for your suggestion, i appreciate.
Yes indeed, works like a charm. Got the addresses with transactions. It turns out that the derivation path
is m/84h/0h/0h. First time i use Electrum, i'm impressed. I tried to figure out the advantages and disadvantage
of Electrum vs Ledger. Someone mention "security":
https://www.bitdegree.org/crypto-wallet-comparison/ledger-nano-x-vs-electrum
is this a reality or a myth?

Hello Everyone,

My question will probably seem stupid, and i apologize for this but there is something i would like to understand.

I opened a blockchain.com wallet and funded it. I made some transactions with it, and today the balance is 0.0001 BTC. So far so good.
Then i made a copy of the 12 words mnemonic from the blockchain account.

To have a better understanding how HD wallet works, i installed the Python bitcoinlib library using pip
on my computer. Unfortunately it says: no transaction and list some addresses with no balance...

Today i used another Python script:
$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$
from mnemonic import Mnemonic
import bip32utils

words="w1 w2 w3 w4 w5 w6 w7 w8 w9 w10 w11 w12"
mnemon.check(words)
seed = mnemon.to_seed(words)
print(f'BIP39 Seed: {seed.hex()}\n')

root_key = bip32utils.BIP32Key.fromEntropy(seed)
root_address = root_key.Address()
root_public_hex = root_key.PublicKey().hex()
root_private_wif = root_key.WalletImportFormat()
print('Root key:')
print(f'\tAddress: {root_address}')
print(f'\tPublic : {root_public_hex}')
print(f'\tPrivate: {root_private_wif}\n')
for i in range(10):
   for j in range(10):
      child_key = root_key.ChildKey(i).ChildKey(j)
      child_address = child_key.Address()
      child_public_hex = child_key.PublicKey().hex()
      child_private_wif = child_key.WalletImportFormat()
      print(f'Child key m/{i}/{j}:')
      print(f'\tAddress: {child_address}')
      print(f'\tPublic : {child_public_hex}')
      print(f'\tPrivate: {child_private_wif}\n')
$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$
I checked the balance of the Child key m/0/0, m/0/1, m/1/0,  m/1/1... They all have a zero balance

So my question is: how to get a list of the address corresponding to non zero balance from the seed of a HD wallet?

Thanks a lot:)
