2  Bitcoin / Bitcoin Technical Support / Derivation path for brute forcing "25th word" on a multisig wallet on: November 26, 2021, 07:17:17 PM
So I added a 25th word to my seed, forgot it, and am (after 6 months of on and off guessing) relegated to brute force (3rdIteration/btcrecover).

Succinct question: what derivation path should I specify in the --bip32-path argument?

  • Hardware: Original Trezor
  • Wallet creating software: Electrum in 2017
  • Wallet setup: 2o3
  • Wallet current software: Electrum in 2021
  • the xpubs are known

Electrum 2021 shows:
  • script type, p2sh
  • cosigner 1 [HW] trezor1 m/45'/0
  • cosigner 2 [HW] trezor2 m/45'/0
  • cosigner 3 unknown unknown.
  • addresses, previous sends, balance (though maybe these are stored and not derived??)

I am trying to crack cosigner 2.

It is possible I copied the xpub from an old wallet so I am questioning the guarentee that m/45'/0 is the correct derivation path.  This is a multisig wallet. In electrum the walletinfo pane lists a derivation path of m/45'/0. Is this a derivation path I can use to crack my xpriv > xpub? Or is this misleading me and is instead a derivation path from xpub x 3 > multisig addresses (in this case my xpriv > xpub path could be anything)?

I've gone through most of the character spaces which I think my passphrase could occupy so I am hoping I am doing something wrong or the transition from 2017 to 2021 electrum has introduced a variation I have missed.

Any tips on what to double check? Notably this[1] post lists m/44'/0/

btcrecover command: python3 btcrecover.py --tokenlist tokenlist2.txt --mpk "xpub69XXX" --bip32-path "m/45'/0" --mnemonic "24 words verified to match my trezor" --bip39

Price is holding up great.  At least we can be happy about that. If everybody keeps believing we won't lose any money!!

Miners improve, hence 5 lines each depicting a different J/GH.  Difficulty varies along the y-axis and is not constant in the plot.

Thanks for posting the plot, it is a nice depiction.

This was interesting, haven't seen it in the thread.

Can someone help me understand what "Exchange" means on lines 4 & 8 of the cash flow document?
9  Economy / Securities / Re: ASICMINER: Entering the Future of ASIC Mining by Inventing It on: May 30, 2014, 05:07:23 PM
Cashflow statement up to May 27:
 - Any electricity for May 25 (Line 18)
 - Was released before payment of May 28 salaries (Line 22)

This makes it hard to estimate whether we are ramping up or withering away in both mining and production.

The balance sheets show a large amount of Materials waiting to be turned into chips. (Line 7)  This looks to be the only bit of hope in this picture.  Even then it looks bleak.  If each chip makes 100% over cost, that bumps assets to 40 USD per share.


Well......

Edit: 7M USD is 17 dollars per share.  Not quite the positive picture.

400 - 1600 PH * 0.49 - 0.9 $/Gh
= $200M - $800M
= 250k - 1M BTC

= .625 - 2.5 BTC/share

(Bitcoin value of sales drops as value of bitcoin increases.)

I was musing today about where mining will end up, and how governments will be involved.  Any thoughts on the feasibility of this sort of government miner distribution (below) and whether there is a future market here?

This is a solution I feel the community is looking for - a small RaspberryPi-esque device which allows me to host a full node apart from my main PC. Ideally such a device would have some small amount of mining power, to distribute voting on the protocol rules throughout the network but I am not sure what type of adoption would be needed to take any percentage of the network hash rate away from institutional miners. But lets think about it.


In the end game mining chips are going to hit a ceiling and technology will advance slower than today.

Governments with a vested interest in Bitcoin may find it beneficial to distribute these slow-hashing nodes to the population and provide a tax credit to pay for part of the electricity. This could use previous generation tech and still make an impact:

Current hash rate: 15,000,000 Gh/s
Population of france: 65,700,000

To get half the network hash rate each person would need to poses ~250Mh.

About 1 AM USB Block Erupter seems like a lot but as asics catch up to current chip-fab technology improvements will slow: the previous gen tech will have an impact much longer and be cheaper.
What other benefits might this have? Well France would secure 50% of mining fees for its population. The network (and France) would be more protected from the attack of another nation state. Decisions about the protocol would be distributed away from mining pools and miners, further increasing network trust.

Hello All,

I want to set up a computer of some sort that is secondary to my desktop computer whose sole purpose will be to host my miners.

I currently use a raspberrypi and minepeon but my pi is not forwarding transactions, can only pool mine, and effectively cannot vote on the network rules.

Any suggestions on the minimum specs and power draw I can achieve while still running a full node?   A point to another thread would be great too.

Thanks

Update. 18 hours and no bitcoin transfer. The bitcoin were deducted from my campbx account balance though. Not sure what to do.
15  Economy / Exchanges / Campbx BTC withdraw, no transaction broadcast on: November 19, 2013, 07:12:31 AM
So I submitted a bitcoin withdraw via the campbx website, but no transaction has appeared on blockchain.info.  It has been six hours and i moved a significant amount of bitcoin.

Anyone else have similar issues?

Thanks

One thing no one has mentioned and i would like to hear opinion on.

With immersion cooling (I expect) the temperature is constant, deviating only slightly from the boiling point of the liquid.  Air is different because its low heat conductance, the more btu output the hotter the chip gets because it can't be carried away quickly.  With such high thermal densities being tested above this won't be a problem.

So what will being able to lock the chips temperature in at a cool 40C be?
(Marginally?) More efficient?
Over clocking potential?

The writeup mentions a longer timeline for large scale production but maybe a consumer device (enclosed cube) with immersion cooling is doable and possibly improves w/GH? Wishful thinking?

Also, could this rescue a gen2 design which had poor thermal properties?

My takehome message from this is asicminer's income was 2 orders of magnitude higher than expense this quarter. (And they get really cheap electricity.)

The owner of this site helped me through the recent site maintenance.  A few errors cropped up which he quickly and transparently took care of.

Just a thumbs up.
