BIP 0032 - Bitcoin Wiki

Bitcoin lingo...lay it on me!

Okay so for fun, for newbies and perhaps even new to some of us more seasoned crypto heads (is that a thing?) how about posting some lingo or terminology that relates to the culture of Bitcoin or even something you may have ‘coined’ yourself?

Ferrum Network Community Update — December 8, 2019

Dear Community,
What an exciting and jammed pack few weeks it has been — with the launch of staking, the 2Key Network partnership, and a major Kudi update — to name a few!
But as the profile of Ferrum continues to grow, it is essential we never stray from the fundamentals that got us this far: hard work, transparency, and a commitment to community.
In this community update, we provide a recap of the last few weeks, and look ahead to a few initiatives we are planning.
Business Update
With the release of the FRM Flexible Staking platform, we took that opportunity to kick the marketing into high gear. These marketing efforts paid off, and we were fortunate to be picked up by top influencers like Teh Moonwalker, Oddgems, and Micro Cap Gems. Here’s what happened the past few weeks.
Tech Update
For those who missed the Tech Update from our CEO Naiem Yeganeh, PhD, here are some highlights:
First Kudi Update
The First Kudi team on the ground in Nigeria continues to make significant progress.
What’s Next
It is critical we capitalize on the attention we have garnered from the team and community efforts, and to start 2020 with a bang. Here are some of the upcoming initiatives we are working on.
Flexible ERC-20 Staking v0.2
We are strongly considering launching another round of staking. We are taking the lessons learned from the first round and improving the experience. Community feedback will be key to make version two even better, so expect to see a series of polls in the coming days.
A Trading Community
A strong group of FRM traders who post technical analysis on social media is great for exposure and great for liquidity. We are currently laying the groundwork to build a trading community to come up with initiatives like trading competitions and special trading rewards. Anyone interested in joining such a community should PM Ian on Telegram.
FRM on Kudi
We have been working hard to add FRM and ETH to the Kudi app so our users can buy it directly with Naira. This will also open up additional utilities for the FRM token, including a premium membership program that will reward users for holding the token and using the app. More details to follow.
Expansion into other Markets
As you may know, one part of our business model is to partner with top notch teams in emerging markets where our fiat gateway + payments app technology can be successful.
We are happy to report that we have started to work with such a team in Brazil and they are in the early stages of launching their own product powered by Ferrum Network. More news to follow.
Conclusion
Thank you all for your continued support of Ferrum Network. 2019 was a really special year that we will never forget. But together we can make 2020 even better!
Very truly yours,
The Ferrum Network Team

Groestlcoin 6th Anniversary Release

Introduction

Dear Groestlers, it goes without saying that 2020 has been a difficult time for millions of people worldwide. The groestlcoin team would like to take this opportunity to wish everyone our best to everyone coping with the direct and indirect effects of COVID-19. Let it bring out the best in us all and show that collectively, we can conquer anything.
The centralised banks and our national governments are facing unprecedented times with interest rates worldwide dropping to record lows in places. Rest assured that this can only strengthen the fundamentals of all decentralised cryptocurrencies and the vision that was seeded with Satoshi's Bitcoin whitepaper over 10 years ago. Despite everything that has been thrown at us this year, the show must go on and the team will still progress and advance to continue the momentum that we have developed over the past 6 years.
In addition to this, we'd like to remind you all that this is Groestlcoin's 6th Birthday release! In terms of price there have been some crazy highs and lows over the years (with highs of around $2.60 and lows of $0.000077!), but in terms of value– Groestlcoin just keeps getting more valuable! In these uncertain times, one thing remains clear – Groestlcoin will keep going and keep innovating regardless. On with what has been worked on and completed over the past few months.

UPDATED - Groestlcoin Core 2.18.2

This is a major release of Groestlcoin Core with many protocol level improvements and code optimizations, featuring the technical equivalent of Bitcoin v0.18.2 but with Groestlcoin-specific patches. On a general level, most of what is new is a new 'Groestlcoin-wallet' tool which is now distributed alongside Groestlcoin Core's other executables.
NOTE: The 'Account' API has been removed from this version which was typically used in some tip bots. Please ensure you check the release notes from 2.17.2 for details on replacing this functionality.

How to Upgrade?

Windows
If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), then run the installer.
OSX
If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), run the dmg and drag Groestlcoin Core to Applications.

ALL NEW - Groestlcoin Moonshine iOS/Android Wallet

Built with React Native, Moonshine utilizes Electrum-GRS's JSON-RPC methods to interact with the Groestlcoin network.
GRS Moonshine's intended use is as a hot wallet. Meaning, your keys are only as safe as the device you install this wallet on. As with any hot wallet, please ensure that you keep only a small, responsible amount of Groestlcoin on it at any given time.

ALL NEW! – HODL GRS Android Wallet

HODL GRS connects directly to the Groestlcoin network using SPV mode and doesn't rely on servers that can be hacked or disabled.
HODL GRS utilizes AES hardware encryption, app sandboxing, and the latest security features to protect users from malware, browser security holes, and even physical theft. Private keys are stored only in the secure enclave of the user's phone, inaccessible to anyone other than the user.
Simplicity and ease-of-use is the core design principle of HODL GRS. A simple recovery phrase (which we call a Backup Recovery Key) is all that is needed to restore the user's wallet if they ever lose or replace their device. HODL GRS is deterministic, which means the user's balance and transaction history can be recovered just from the backup recovery key.

ALL NEW! – GroestlcoinSeed Savior

Groestlcoin Seed Savior is a tool for recovering BIP39 seed phrases.
This tool is meant to help users with recovering a slightly incorrect Groestlcoin mnemonic phrase (AKA backup or seed). You can enter an existing BIP39 mnemonic and get derived addresses in various formats.
To find out if one of the suggested addresses is the right one, you can click on the suggested address to check the address' transaction history on a block explorer.

ALL NEW! – Vanity Search Vanity Address Generator

NOTE: NVidia GPU or any CPU only. AMD graphics cards will not work with this address generator.
VanitySearch is a command-line Segwit-capable vanity Groestlcoin address generator. Add unique flair when you tell people to send Groestlcoin. Alternatively, VanitySearch can be used to generate random addresses offline.
If you're tired of the random, cryptic addresses generated by regular groestlcoin clients, then VanitySearch is the right choice for you to create a more personalized address.
VanitySearch is a groestlcoin address prefix finder. If you want to generate safe private keys, use the -s option to enter your passphrase which will be used for generating a base key as for BIP38 standard (VanitySearch.exe -s "My PassPhrase" FXPref). You can also use VanitySearch.exe -ps "My PassPhrase" which will add a crypto secure seed to your passphrase.
VanitySearch may not compute a good grid size for your GPU, so try different values using -g option in order to get the best performances. If you want to use GPUs and CPUs together, you may have best performances by keeping one CPU core for handling GPU(s)/CPU exchanges (use -t option to set the number of CPU threads).

ALL NEW! – Groestlcoin EasyVanity 2020

Groestlcoin EasyVanity 2020 is a windows app built from the ground-up and makes it easier than ever before to create your very own bespoke bech32 address(es) when whilst not connected to the internet.
If you're tired of the random, cryptic bech32 addresses generated by regular Groestlcoin clients, then Groestlcoin EasyVanity2020 is the right choice for you to create a more personalised bech32 address. This 2020 version uses the new VanitySearch to generate not only legacy addresses (F prefix) but also Bech32 addresses (grs1 prefix).

ALL NEW! – Electrum Personal Server

Groestlcoin Electrum Personal Server aims to make using Electrum Groestlcoin wallet more secure and more private. It makes it easy to connect your Electrum-GRS wallet to your own full node.
It is an implementation of the Electrum-grs server protocol which fulfils the specific need of using the Electrum-grs wallet backed by a full node, but without the heavyweight server backend, for a single user. It allows the user to benefit from all Groestlcoin Core's resource-saving features like pruning, blocks only and disabled txindex. All Electrum-GRS's feature-richness like hardware wallet integration, multi-signature wallets, offline signing, seed recovery phrases, coin control and so on can still be used, but connected only to the user's own full node.
Full node wallets are important in Groestlcoin because they are a big part of what makes the system be trust-less. No longer do people have to trust a financial institution like a bank or PayPal, they can run software on their own computers. If Groestlcoin is digital gold, then a full node wallet is your own personal goldsmith who checks for you that received payments are genuine.
Full node wallets are also important for privacy. Using Electrum-GRS under default configuration requires it to send (hashes of) all your Groestlcoin addresses to some server. That server can then easily spy on your transactions. Full node wallets like Groestlcoin Electrum Personal Server would download the entire blockchain and scan it for the user's own addresses, and therefore don't reveal to anyone else which Groestlcoin addresses they are interested in.
Groestlcoin Electrum Personal Server can also broadcast transactions through Tor which improves privacy by resisting traffic analysis for broadcasted transactions which can link the IP address of the user to the transaction. If enabled this would happen transparently whenever the user simply clicks "Send" on a transaction in Electrum-grs wallet.
Note: Currently Groestlcoin Electrum Personal Server can only accept one connection at a time.

UPDATED – Groestlcoin Sentinel 3.5.06 (Android)

Groestlcoin Sentinel is a great solution for anyone who wants the convenience and utility of a hot wallet for receiving payments directly into their cold storage (or hardware wallets).
Sentinel accepts XPUB's, YPUB'S, ZPUB's and individual Groestlcoin address. Once added you will be able to view balances, view transactions, and (in the case of XPUB's, YPUB's and ZPUB's) deterministically generate addresses for that wallet.
Groestlcoin Sentinel is a fork of Groestlcoin Samourai Wallet with all spending and transaction building code removed.

Best exchange for tiny amounts of fork coins? (BCH, BSV, etc)

A buddy of mine had a pre-SegWit BIP39 seed from a couple years back. I helped him figure it out and sweep his coins to a new bech32 address. For my trouble, he told me I could keep the keys and use them to claim the various Bitcoin forks that have popped up since he bought those coins.
It's not a lot of money by a long shot. My guess is that BCH BSV and BTG combined will net me maybe 20 bucks. But I'm stuck inside on account of this coronavirus thing so I figure I may as well tinker around with blockchains and get myself a 12 pack outta all this. As a boredom buster if nothing else
The problem is the amounts are really small, too small to meet the minimum threshold at Changelly. Also, I know there are a lot of Bitcoin forks but I can't find an exchange that supports half of them. Is there a good exchange for this sort of thing? Preferably without KYC so I don't have to wait for all that to go through? I was hoping to swap them out for BTC or LTC

Bitcoin Core v0.13.0rc1 binaries are available for testing.

submitted by Michagogo to Bitcoin [link] [comments]

I'm sick of managing multiple BCH wallets & balances & seeds on memo.cash, blockpress.com, yours.org, honest.cash, telescope, etc. To make things easier for adoption, we should allow one BCH balance for all spending, and new apps & services should allow importation of seed words.

Just look at the disaster with Yours.org. Many people didn't write down their Yours.org seed words, and now they're locked out of their Yours.org BCH balances.
The path forward should probably be through the Telescope browser add-on or badgerwallet.cash wallet, with seed word importation. Telescope project is currently managed by u/adangert and funded by Bitmain.
This way, people can maintain one big BCH balance on a hardware wallet (like Ledger), and a smaller "spending" BCH balance on a Bitpay-compatible wallet, like Bitcoin.com wallet.
Import the Bitcoin.com wallet BCH seed words (BIP39; derivation path m/44'/0'/0') into Telescope, and people could then do all their spending from one BCH balance & seed words that they control.
IMHO, that would make the BCH ecosystem more scalable for normie users.

BCH sent to P2WPKH-P2SH Address, recovery shows mixed results...

I have a case here where a client of mine used a BitCoin ATM, and inadvertently used the 'BitCoin CASH' option instead of 'BitCoin', when he was using himself a Mycelium HD Wallet on a SegWit Address. Mistakes were made, but we have held onto the hope that at somepoint recovery would be possible.

With the May 15 Fork and the addition of SegWit recovery to the BitcoinABC codebase, recovery became possible, and the BCH chain survived an attempt at a double-spend attack by some thrifty miner(s) who realized that they could swoop in and take some of these trapped coins.

Since then, a couple guides have arisen that give an explanation of how to do a recovery, if those BCH sent to a 3xxxx Segwit address have the correct 'things', primarily a corresponding private key.

Here is my question/problem --- my BCH wallet is an HD Wallet created in Mycellium, and this was the 2nd 'account' in the wallet, and the 'second' key in that account. The BCH Derivation code is m/49'/0'/1'/0/1 . Problem is, I can only find a private key corresponding to the p2wskh-ps2h: key, and the p2sh: key in not importable in to Electron Cash wallet. How can I find a private key that corresponds to that wallet location in Electron Cash?

Here are some details:
3CSUDH5yW1KHJmMDHfCCWShWgJkbVnfvnJ
address the BCH was sent to... now, this address had BCH AND BTC sent to it at some point, and the BTC was spent, revealing the public key hash.
18dWL1ANKPwrhnbvNhrTDy8sxUzDGZ7YH2 is the 'legacy address' that Electron Cash spits out when I put the p2wskh-ps2h:"private key'

bitcoincash:pp67j94cfvnfg727etymlst9jts3uhfdkurqvtj2un is the public key address that Electron Cash shows the transaction occured on. If you put that key into the Electron Cash as a 'watch only' wallet, it still shows a 0.58 BCH Balance.

Problem is, I can't find out how to retrieve the private key for this address... the private key for 3CSUDH5yW1KHJmMDHfCCWShWgJkbVnfvnJ just gives the 18dWL1ANKPwrhnbvNhrTDy8sxUzDGZ7YH2 address in Electron Cash instead of bitcoincash:pp67j94cfvnfg727etymlst9jts3uhfdkurqvtj2un ....

Anyone think that have a hint where to check next? I have tried the BIP39 recovery site and can generate xprv/yprv keys, but none of these seem to be giving me the private key needed for the Derivation set of the HD wallet. Any help would be greatly appreciated!

r/Bitcoin recap - April 2018

Hi Bitcoiners!
I’m back with the sixteenth monthly Bitcoin news recap.
It's easy for news and developments to get drowned out by price talk, so each day I pick out the most popularelevant/interesting stories in Bitcoin and save them. At the end of the month I release them in one batch, to give you a quick (but not necessarily the best) overview of what happened in Bitcoin over the past month. Lots of gems this time around!
You can see recaps of the previous months on Bitcoinsnippets.com

Channel should be open now
Chill05/10/2019
you all rock!
just getting that out of the way :wink:
Tron05/10/2019
Cheers everyone.
theking05/10/2019
Hi fabulous dev team!
Hans_Schmidt05/10/2019
Howdy!
Tron05/10/2019
No specific agenda today.
Questions?
Has everyone seen Zelcore wallet, and Spend app?
theDopeMedic05/10/2019
Any major development status updates that haven't been listed in #news?
Synicide05/10/2019
How was the meetup yesterday? I heard it would be recorded, it is uploaded anywhere yet?
Tron05/10/2019
And Trezor support on Mango Farm assets?
@Synicide Yes it was recorded. The Bitcoin meetup organizer has the video.
I talked about Ravencoin, but mostly about the stuff that was being built on/with/for Ravencoin.
There was about 70% overlap with folks who were at the Ravencoin meetup in March.
Synicide05/10/2019
awesome, looking forward to watching it when it's available
Tron05/10/2019
I'll hit up James and see if he's posting the video.
S1LVA | GetRavencoin.org05/10/2019
@theDopeMedic I'd follow github if youre interested in development status
Synicide05/10/2019
zelcore looks super slick. Been meaning to research its security more with the username/pw being stored on device
Chill05/10/2019
How is the progress on the restricted assets and testnet coming along? A secondary question would be about the approximate fork timeframe.
S1LVA | GetRavencoin.org05/10/2019
Has anyone heard from the community dev (BW) working on Dividends?
Rikki RATTOE Sr. SEC Impresantor05/10/2019
Any word on BW and his progress w dividends?
@S1LVA | GetRavencoin.org LOL
Tron05/10/2019
@S1LVA | GetRavencoin.org Great question. I haven't heard.
Synicide05/10/2019
last meeting BlondFrogs said he would try to connect with BW as he was sick with the flu at the time. Maybe he has an update
S1LVA | GetRavencoin.org05/10/2019
I've tried to get in contact, but with no success.
Rikki RATTOE Sr. SEC Impresantor05/10/2019
Got a funny feeling...
Jeroz05/10/2019
Last time we left off with someone mentioning a foundation and Tron saying let’s discuss that next time iirc
kryptoshi05/10/2019
Has anyone taken a look at the merits for this proposal? Thoughts? https://medium.com/systems-nexus/modified-x16r-algorithm-proposal-for-constant-hash-rate-in-short-time-164711dd9044
Medium
Modified X16R algorithm proposal for constant hash rate in short time
Interpretation Lens V. a0.01
Tron05/10/2019
I did see it. Does anyone think this is a problem?
Synicide05/10/2019
It looks interesting... but I'm not sure what it is trying to solve. Looking at netstats, our 1 hour average block time is perfectly 1 minute
S1LVA | GetRavencoin.org05/10/2019
Last I heard from him he expressed how important finishing the code was. I wouldnt jump to conclusions on his absence within the community.
Synicide05/10/2019
x16r by nature will fluctuate, but DGW seems to be doing a good job keeping consistent block times
Tron05/10/2019
Because of relatively broad distribution across the algorithms, the block times are fairly consistent. It is possible, but very, very unlikely to get a sequence that takes up to 4x longer, but that's super rare, and only 4 minutes.
We did some timing analysis of the algorithms early on. A few are 1/2 as long as SHA-256 and some are up to 4x longer. But when you randomly select 16 it usually comes out about even.
Synicide05/10/2019
1hr avg: 1.02min - 24hr avg: 1min
I think we should focus on building, and not trying to fix what isnt necessarily broken
Tron05/10/2019
Agreed.
Rikki RATTOE Sr. SEC Impresantor05/10/2019
Agreed
Tron05/10/2019
Is everyone ok with the frequency (every other week) of this discussion?
Jeroz05/10/2019
(Added thumbs down to measure)
Tron05/10/2019
@Jeroz Did you do thumbs-up and thumbs down?
S1LVA | GetRavencoin.org05/10/2019
Seems appropriate. Its not like the devs dont poke around here and chat anyways.
Tron05/10/2019
Anything critical that we should be aware of?
Jeroz05/10/2019
When I need a dev, I poke a dev. When that dev is unavailable. I poke another one :smiley:
Hans_Schmidt05/10/2019
BlondFrogs was testing some github code last month to create a dividends snapshot database of asset holders at a given blockheight. Is that planned for inclusion? That's the only thing needed for dividends.
Jeroz05/10/2019
I hope I didn’t offend any devs
With poking around
Rikki RATTOE Sr. SEC Impresantor05/10/2019
Was thinking voting would be an excellent use case for restricted assets. Local communities, nations, etc... could kyc their residents
radiodub05/10/2019
Is x16r will remain fpga mineable
Tron05/10/2019
@Jeroz We're hard to offend.
Chill05/10/2019
Is the general dev feeling that the next fork should and will include everything needed for the next 6-9 months (barring something completely unforeseen)?
Jeroz05/10/2019
I know :smile:
Tron05/10/2019
@radiodub Nearly impossible to stop FPGAs and still keep GPUs
Jeroz05/10/2019
About that: voting is another hard fork right? Not too soon?
Tron05/10/2019
FPGAs can be reprogrammed as fast. It is silicon (true ASIC) that we can obsolete with a tiny change.
@Jeroz Messaging, voting, Tags, Restricted Assets would require a hard fork (upgrade).
We could do them each individually, but folks get weary of upgrades, so current plan is to roll them together into one.
MrFanelli™05/10/2019
Good idea
Jeroz05/10/2019
Oh voting too?
MrFanelli™05/10/2019
People will like that
Jeroz05/10/2019
I thought that was coming later
Tron05/10/2019
Voting is the one that isn't being worked on now. Tags and Restricted assets have taken precedence.
Jeroz05/10/2019
I know. But you plan on waiting to fork until voting is also done?
That would have my preference tbh
But I can see an issue with too many things at the same time
Tron05/10/2019
If someone wants to step in, we've had one of our devs sidelined and he was working on BlockBook support so more light wallets can connect to Ravencoin. Mostly test cases needed at this point.

At what point would RVN community consider moving to ASICs because having a Bitcoin level of security would eventually be needed?

@Rikki RATTOE Sr. SEC Impresantor There's nothing inherently wrong with ASICs but it tends to centralize to data centers and less opportunity for anyone to just run their gaming rig overnight and collect RVN.
Welcome Blondfrogs
MrFanelli™05/10/2019
Asics are too expensive. If we want normal people to mine, then we cant be an asic network
Rikki RATTOE Sr. SEC Impresantor05/10/2019
@Tron True but what happens when the chain needs a Bitcoin level of protection?
Tron05/10/2019
More GPUs, more FPGAs
MrFanelli™05/10/2019

Tron05/10/2019
It's all relative. It is cost to attack. If an ASIC isn't available for rent, then only option is rental of non-allocated GPUs
Rikki RATTOE Sr. SEC Impresantor05/10/2019
@Chill Eventually everyone will need FPGAs to be profitable on RVN, at that point I don't see why we just don't make the switch to ASICs
Tron05/10/2019
Also, as much as we don't focus on price, the price does matter because it determines the amount of electricity and hardware will be deployed to get the block reward. Price increase means more security, more mining means more security means higher price.
It's a circle.

liqdmetal05/10/2019
why not? what is the logic on non-protocol dividends
assets + protocol dividends is nirvana
[Dev-Happy] Blondfrogs05/10/2019
dividends is pretty much sending payments to addresses. Right now, you would have to do this manually. The dividends code, will allow this to be done quicker and easier.
No consensus changes are required.
Tron05/10/2019
New Android wallet is BIP44 and original Android wallet is BIP32/BIP39 so the words will not find the funds. You'll need to send them to another wallet, and then send them to new BIP44 derived address.
liqdmetal05/10/2019
we already have payments to addresses
so dividends is not a feature so much as simple wallet script
Hans_Schmidt05/10/2019
@[Dev-Happy] Blondfrogs The dividend code changes look risky'er to me than messaging. Would you consider "tags" branch test-ready?
[Dev-Happy] Blondfrogs05/10/2019
Not yet @Hans_Schmidt
Dividends is easier then you would think if coded correctly. I still haven't seen the code from the community developer. Excited to view it though.
Hans_Schmidt05/10/2019
@[Dev-Happy] Blondfrogs Sorry- I meant restricted, not dividend
kryptoshi05/10/2019
@Tron on the Android wallet, anyone successfully added their own node and got it to sync faster? Always have issues. I have a supped up node and cannot get it to work with the Android wallet...
[Dev-Happy] Blondfrogs05/10/2019
@Hans_Schmidt Oh, that makes more sense. Yes, they are very risky! That is why we are going to create a new bug bounty program for restricted assets testing.
Rikki RATTOE Sr. SEC Impresantor05/10/2019
Once the network does get flooded w FPGAs, should we even consider changing the algo a couple times a year? That would only give bitstream developers added time to hoard their creations for themselves

kryptoshi05/10/2019
@Rikki RATTOE Sr. SEC Impresantor Yes Soon TM lol. :soontm:
Tron05/10/2019
@kryptoshi There are some things we can do to speed it up. For a new wallet, it shouldn't need to sync. For recovered wallet, it needs to sync from beginning of BIP44 wallet support on iOS so words can be moved between the two.
Other options include grabbing the first derived address and looking it up on an explorer to see when it was first used and sync from there.
Another option is to add an optional number with the 12 words so it knows when to start syncing.
There isn't a good reason on an SPV wallet to sync before the seed was created.
kryptoshi05/10/2019
Cool. Glad you are looking at speedup options.. :right_facing_fist: :left_facing_fist:

Attention, benevolent BCH miners: A BCH segwit-recovery service is sorely needed!

These BCH are now recoverable; please read the update at the end of the post!

 
 

Background

In the short while since segwit activated on the BTC network and segwit addresses even-more-recently became the default for receiving BTC in the Trezor wallet - and perhaps other wallets too (soon?) - people have started accidentally sending their BCH to BTC-segwit addresses.
 
Due to the fact(s) that...
a) the BCH network supports P2SH (i.e. addresses starting with 3), but not segwit
... and ...
b) the sending wallets thus have no way of knowing that P2SH-wrapped segwit addresses really are "hiding" a segwit redeemscript
... people are losing access to their BCH, there's currently no way to prevent this, and it will continue happening.
 

Examples

(These are just the ones that I've noticed, but I'm sure there are many more that go straight to the various wallet service providers' support teams instead of via Reddit.)
 
To add insult to injury, the unlucky BCH owners are routinely told that there's no way to recover the coins (including by myself at the start) due to BCH not supporting segwit. And while that's currently true, it is ultimately only a half-truth.
After all, segwit opponents have often said that the satoshis in segwit addresses would be "anyone-can-spend" if the miners didn't enforce the segwit rules (i.e. ensuring that there's a proper witness/signature in the "segregated" part of the txs).
And on the BCH network the segwit rules aren't being enforced!
 

A Partial Solution

So I did some digging (e.g. in the segwit documentation and P2SH specification, BIP16) and came to the conclusion, which I'm sure that many have before me, that in order to spend money sent to a P2SH-wrapped segwit address, you only need to know the public key of the address (or more precisely: the RIPEMD160 hash of the SHA256 hash of a the public key).
Yes, a hash derived from the public key, not the private key.
Luckily, the 3-addresses don't by themselves reveal this public key hash, or anyone could've made "signed" txs from these "BCH-segwit" addresses - and someone probably already would have.
 

More Problems

So, given that it's relatively easy (for a technically inclined person, anyway) to get the public key corresponding to an address from their BIP39 mnemonic (aka wallet recovery seed), why aren't people re-claiming their BCH from these addresses?
Well, the "signature" that's needed isn't really a digital signature in the normal sense. Regular cryptocurrency transactions include a digital signature that doesn't reveal the private key that was used to make the signature in question. What's needed to "sign" for BCH-segwit addresses, however, is just literally including the public key hash that was mentioned above instead of a proper digital signature.
This means that anyone who sees such a transaction can just extract the public key hash from it - and then go on to create a conflicting transaction, using the same public key hash, that sends the same money elsewhere (to themselves, I would presume).
Technically, the second transaction would be a double-spend of the original and, as with all double-spends, it's the miners that would be the final arbiters of which transaction gets recorded in the block chain.
Additionally, a malicious miner could just create their own version of the transaction, either overtly redirecting the money to themselves, or covertly by changing the transaction to have no monetary outputs (i.e. all the money would go to the miner as "fee").
But the problems don't stop there. These segwit-spending transactions would be non-standard and as such wouldn't be relayed to the miners in the first place, nor would it be mined by miners even if it reached them (provided that the nodes and miners run with the default policy of ignoring non-standard txs, that is).
 

Suggested Solution

What we need is one or more trustworthy (yes, trust would unfortunately be required) miners to step up and make a BCH Segwit-Recovery Service for this particular purpose, in a somewhat similar way that they provided acceleration services for the BTC network (example1 and example2).
 
So... Does anyone know if a) miners are already working on this or b) know how to get in touch with them about this?
Or are there any benevolent miners here, that would like to:
 
/btc users, feel free to notify any miner contacts you may have - let's make this happen!
 
 

Update 1 (2017-09-11)

I made a proof-of-concept frontend to "show" what I'm envisioning such a service would look like for the end users (obviously it's ugly and needs to include javascript for key/hash/address validation, etc., but it should get the intention across), here:
https://btctroubadour.github.io/bch-recovery.html

Update 2 (2017-11-21)

It looks like some greyhat/vigilante, working with an unknown miner, was able to unilaterally claim some of the BCH that were "stuck" in BTC-segwit addresses (namely, the ones for which the public keys were revealed by the owners spending BTC from the same addresses), as explained in this post and comments: https://np.reddit.com/Bitcoin/comments/7eixcu/recovering_bch_sent_to_segwit_addresses/
For those that are affected by this, it means you no longer control your BCH (they were "stolen" by the greyhat), but he seems to be offering to give them back if you agree to letting him keep 30 % for his service (or "service", however you look at it). Either way, and given the alternative (100 % loss), you should certainly check if you're affected and decide how you want to proceed. As if that wasn't enough to deal with, there seems to be a ~2 week deadline, until "December 5th, 2017 at 23:59:59 UTC", after which it seems he's decided he's entitled to keep your money. :(

Update 3 (2017-11-28)

It looks like the greyhat has turned white! He's now offering to give back, for free, any and all BCH that were transferred to him (yes, 100 %!). Read his new update post and check if you were affected by this transfer.

Update 4 (2017-12-05)

Benevolent BCH miner finally found! The good people at btc.com have announced an automated BCH-segwit-recovery service, just as I outlined in my original post. Thanks a lot to Stellaluna19 for bringing it to my attention.
Here are links to btc.com's Twitter announcement as well as the recovery service itself:
https://twitter.com/btccom_official/status/933682190424199169

(Note that SatoshiLabs/Trezor developer, and well-known whitehat, -johoe have suggested some improvements to secure the process outlined by btc.com. You can read his suggestions in the last paragraph of this post - or in this one.)

Question regarding the derivation path

Edit #1:
Found an explanation for the different index number: https://coinomi.freshdesk.com/support/solutions/articles/29000009767-can-i-use-my-address-for-mining-why-did-my-address-change-

Main:
Hi, I'm looking to sweep funds from a gift Coinomi wallet into my current wallet. When using the recovery tool to make the sweep of DOGE, I've noticed the address that I'm looking for has a derivation path[1] of m/44'/3'/0'/0/3.

The Coinomi Support article for the recovery tool[2] states the following:
The list of addresses is generated in the same order as the Coinomi app. You do not need to look through thousands of addresses (unless you have used thousands of addresses in the app as well). For example, the third address that was used in the app will be the third address on this list as well.

However, I've restored the gift wallet from scratch, only adding DOGE, and the same behavior stilll occurs.

So my questions are:
  1. Why was the address generated with a derivation path index of 3, instead of 0?
  2. What is the benefit of doing so?

(BTW, the recovery tool given by Coinomi app[3] is different from the one listed in the Coinomi Support page[4])

Here is how to create SegWit BIP49 wallets and addresses in Electrum.

Posted this earlier as a comment in /bitcoin -- hopefully this can help some of you here as well.
So, with the way Electrum sets up SegWit wallets, most mining pools and exchanges don't yet recognize the addresses. This is because Electrum uses "full-SegWit" bech32 implementation.
In order to work around this, you can create the more "backwards-compatible friendly" BIP49 implementation of a SegWit wallet via Ian Coleman's website then import into Electrum.
The downside to the BIP49 implementation is that your SegWit transactions are 10% larger than bech32 SegWit. The upside is that Slush Pool and loads of other sites will send those sweet BTC payouts to a BIP49 address.
Here's a step-by-step.
Note: Please take all available security precautions when generating your seed--VPN, https, firewalls, etc.
  1. Go to this site
  2. Click "BIP49 derivation path" and generate. Those fifteen words are your wallet seed.
  3. In Electrum, FileNew/RestoreStandard wallet and click "Next"
  4. Select "I already have a seed" and click "Next"
  5. Click "Options" box and check "BIP39" Seed then click OK
  6. input fifteen words from Ian Coleman's site and click "Next"
  7. On the "Derivation" screen, replace m/44'/0'/0' with m/49'/0'/0' and click "Next"
  8. If you want wallet key encryption (STRONGLY RECOMMENDED) enter a strong password and store it somewhere safe, then click "Next"
  9. Look at your wallet's addresses: they should all begin with "3" (if they don't, start over with a new seed).
  10. Enjoy your new SegWit backwards-compatible P2SH-P2PKH wallet.
Donations: 3LQ2QWQHcYaCAfNXBuoXygmsKAGGJEa7rW
EDIT: If you have a Trezor or Nano S with Segwit, you can basically follow this guide without any Seed Generation and replace "I already have a seed" in step 4 with "Use a hardware device."

Groestlcoin Release September 2018

Introduction

As always, the past 3 months since 22nd June have been crazy busy. The bears might still be around, but the show must go on and of course has not slowed the Groestlcoin development team in the slightest. Here’s a quick overview of what has already happened since the last release: - Integrated into the bitbns exchange, with the ability to buy Groestlcoin directly with the Indian Rupee. - Groestlcoin Rebrand Vote – Whilst there was much talk and push for a rebrand vote, the overall result was almost unanimously in favour of keeping our unique and conversation-starting name. With just 83 votes to Rebrand, and 2577 votes to No Rebrand. Thank you for all who voted, the funds raised are being used to fund ongoing hosting and development costs. - Integrated into the Cryptobridge exchange. Cryptobridge is a popular decentralised exchange where you always hold the private keys to your funds, only YOU have access to them. - Groestlcoin has been added to SimpleSwap – Groestlcoin can now be swapped with over 100 other cryptocurrencies, without signing up! - Groestlcoin has been added to UnoDax, one of the leading cryptocurrency exchanges in India, with TUSD, BTC and INR trading pairs. - Groestlcoin has been added to SwapLab.cc, where you can buy Groestlcoin using Bitcoin and over 50 other altcoins. Purchasing with VISA/Mastercard is coming VERY SOON. Discussed later: - Groestlcoin has been listed on #3 largest exchange in the world on volume, Huobi Global! More on this to come further on in the announcements. - Groestlcoin has been added to the Guarda Multi-Currency Wallet. - Groestlcoin has been added to Melis Multi-Device, Multi-Account, Multi-Platform, Multi-Signature advanced wallet! Already this list is far more than most other cryptocurrencies have achieved in the past 3 months. But this is just the tip of the iceberg of what has been developed.

What's been Happening?

GRSPay Released

We are so excited for this, that it has it's own separate reddit thread. Head over there now at https://www.reddit.com/groestlcoin/comments/9ikr5m/groestlcoin_releases_grspay/? to see more on this!
https://www.melis.io/assets/logo-navbar-4b6f0d372f15b2446d3fa4c68f346e4fb08ee113941186cee58fd6135f3f8b7d.svg

Melis Wallet

The the most advanced wallet for Bitcoin, Bitcoin Cash, Litecoin and now Groestlcoin.
With Melis you have the complete control of your bitcoins and private keys, you can define spending limits policies and make use of two or more factors authentication. Melis is open source, published on GitHub.

How Melis Works?

You can create as many accounts as you want. An account is a part of your wallet that can be customised to your requirements. You can choose how many co-signers are required to spend funds. The accounts are completely independent and act like separate wallets from each other but can be accessed via the same details. A core feature of Melis is the ability to set a ‘primary’ device. With this you can set an account as ‘Secure’ so it is only viewable (and accessible at all) from the Primary device. You can have a savings account hidden from the outside world whilst also having your ‘spending’ funds available on the go. With Melis you can create a multi-signature account between N people, where up to N signatures are required to sign a transaction, choosing if any of those should be mandatory.

In short, we're a bunch of people that claim to be Crypto Evangelists. We strongly believe in cryptocurrencies, and our main promise is to push them up so more people get involved and take all the advantages they offer.

More information from Blockchain Financial

Back in 2014, the world was taken by storm when Facebook approved the first cryptocurrencies tipping apps. The first was for Dogecoin, and the second was for multiple coins.
The project was hosted on whitepuma.net, and persisted for almost two years, built up a massive user community and gave a home to Bitcoin, Litecoin, Dogecoin and dozens of other bitcoin-based altcoins.
After very active months, the tipping hype started to fade away. Then, the developers decided to jump into the next stage: bringing not only tipping, but also mining and a widget that could be embedded on websites to allow everyone to accept payments. Sadly, the work was never completed because the project started to require an unsustainable amount of resources. Then, in a painful decision, a shutdown was announced by December 2015.
A couple of months after whitepuma.net was closed, the source code was released by its creator as Open Source on GitHub. But it wasn't maintained.
Now, some of the original members of the dev and admin teams gathered up with a handful of the WhitePuma's elite users, and decided to make something good with the best pieces of the old source code. That, with fresh new ideas and the power of the BardCanvas engine, synthesized the core of Blockchain Financial.

A new major Groestlcoin Core version 2.16.3 is now available for download which includes both a Denial of Service component and a critical inflation vulnerability, so it is recommended to upgrade to it if you are running a full Groestlcoin node or a local Groestlcoin Core wallet.
v2.16.3 is now the official release version of Groestlcoin Core. This is a new major version release with a very important security updates. It is recommended to upgrade to this version as soon as possible. Please stop running versions of Groestlcoin Core affected by CVE-2018-17144 ASAP: These are 2.13.3 and 2.16.0.
As a result in this, all exchanges and services have been asked to upgrade to this version, so please be patient if wallets go in to maintenance mode on these services.

What's new in version v2.16.3?

This is a major release of Groestlcoin Core fixing a Denial of Service component and a critical inflation vulnerability (https://nvd.nist.gov/vuln/detail/CVE-2018-17144) exploitable by miners that has been discovered in Groestlcoin Core version 2.13.3 and 2.16.0. It is recommended to upgrade to 2.16.3 as soon as possible. If you only occasionally run Groestlcoin Core, then it's not necessary to run out and upgrade it right this second. However, you should upgrade it before you next run it. If you know anyone who is running an older version, tell them to upgrade it ASAP. Stored funds are not at risk, and never were at risk. At this time we believe over half of the Groestlcoin hashrate has upgraded to patched nodes. We are unaware of any attempts to exploit this vulnerability. However, it still remains critical that affected users upgrade and apply the latest patches to ensure no possibility of large reorganizations, mining of invalid blocks, or acceptance of invalid transactions occurs.

The Technicals

In Groestlcoin Core 2.13.3, an optimization was added (Bitcoin Core PR #9049) which avoided a costly check during initial pre-relay block validation that multiple inputs within a single transaction did not spend the same input twice which was added in 2012 (Bitcoin Core PR #443). While the UTXO-updating logic has sufficient knowledge to check that such a condition is not violated in 2.13.3 it only did so in a sanity check assertion and not with full error handling (it did, however, fully handle this case twice in prior to 2.1.0.6). Thus, in Groestlcoin Core 2.13.3, any attempts to double-spend a transaction output within a single transaction inside of a block will result in an assertion failure and a crash, as was originally reported. In Groestlcoin Core 2.16.0, as a part of a larger redesign to simplify unspent transaction output tracking and correct a resource exhaustion attack the assertion was changed subtly. Instead of asserting that the output being marked spent was previously unspent, it only asserts that it exists. Thus, in Groestlcoin Core 2.16.0, any attempts to double-spend a transaction output within a single transaction inside of a block where the output being spent was created in the same block, the same assertion failure will occur. However, if the output being double-spent was created in a previous block, an entry will still remain in the CCoin map with the DIRTY flag set and having been marked as spent, resulting in no such assertion. This could allow a miner to inflate the supply of Groestlcoin as they would be then able to claim the value being spent twice.
Groestlcoin would like to publicly thank Reddit user u/Awemany for finding CVE-2018-17144 and reporting it (https://lists.linuxfoundation.org/pipermail/bitcoin-core-dev/2018-Septembe000064.html).

Groestlcoin EasyVanity Released

Groestlcoin EasyVanity is a Windows app is built from the ground-up in C# and makes it easier than ever before to create your very own bespoke Groestlcoin address(es), even whilst not connected to the internet! You can even generate multiple keys with the same prefix and leave it on overnight whilst your CPU or GPU collects and stores these addresses locally.
If you're tired of the random, cryptic addresses generated by regular groestlcoin clients, then Groestlcoin EasyVanity is the right choice for you to create a more personalized address.

Features

• Ability to continue finding keys after first one is found • Includes warning on startup if connected to the internet • Ability to output keys to a text file (And shows button to open that directory) • Ability to make your match case sensitive (Where possible) • Show and hide the private key with a simple toggle switch, and copy the private key straight to your clipboard • Show full output of commands • Includes statistics whilst the application is running • Ability to choose between Processor (CPU) and Graphics Card (GPU) • Automatically detects 32 or 64 bit systems • Features both a Light and Dark Material Design inspired Themes • EasyVanity's search is probabilistic, and the amount of time required to find a given pattern depends on how complex the pattern is, the speed of your computer, and whether you get lucky. • EasyVanity includes components to perform address searching on your CPU (vanitygen) and your OpenCL-compatible GPU (oclvanitygen). Both can be built from source, and both are included in the Windows binary package. • Prefixes are exact strings that must appear at the beginning of the address. When searching for prefixes, Easyvanity will ensure that the prefix is possible, and will provide a difficulty estimate. • The percentage displayed just shows how probable it is that a match would be found in the session so far. If it finds your address with 5% on the display, you are extremely lucky. If it finds your address with 92% on the display, you are unlucky. If you stop EasyVanity with 90% on the display, restart it, and it finds your address with 2% on the display, your first session was unlucky, but your second session was lucky. • EasyVanity uses the OpenSSL random number generator. This is the same RNG used by groestlcoin and a good number of HTTPS servers. It is regarded as well-scrutinized. Guessing the private key of an address found by EasyVanity will be no easier than guessing a private key created by groestlcoin itself. • To speed up address generation, EasyVanity uses the RNG to choose a private key, and literally increments the private key in a loop searching for a match. As long as the starting point is not disclosed, if a match is found, the private key will not be any easier to guess than if every private key tested were taken from the RNG. EasyVanity will also reload the private key from the RNG after 10,000,000 unsuccessful searches (100M for oclvanitygen), or when a match is found and multiple patterns are being searched for. • Free software - MIT. Anyone can audit the code. • Written in C# - The code is short, and easy to review.

Cold Storage Idea

https://preview.redd.it/hf270gko90211.jpg?width=4032&format=pjpg&auto=webp&s=5a12a2b6464eac8ac827983961d40451e292a6fb
Preface: This is a TEST wallet! There are no bitcoins stored here, no will there ever be! (or if there are, they weren't mine!)
TLDR: Scrambled the order of the 24 words using a password, stamped onto 22 GA weldable steel plate. What could go wrong? I feel like I'm overlooking something fairly simple that makes this insecure.
So, I recently got a Ledger Nano S, and have had plenty of time to explore it, generate several wallets (including adding a 25th word for extra security), add them as watch-only addresses into Electrum, or use the Nano S with Electrum to send/receive funds. I feel pretty confident I know what I'm doing, but wanted your opinions on how I should handle long-term key storage. The idea thats been floating around my head for a while has been to stamp it out in metal (I know a few companies offer "build-it-yourself" setups, but I wanted something a bit cheaper). This is the result of my experiment.
"But wait!" I hear you say, "you've just posted your private keys onto the internet! Oh noes! You fool!" Except that I'm sure this sequence of words will be plugged into a handful of wallets to see whats up, only to find out that it doesn't work. Thats because the order of the words is encoded (and no, the upside down A in WASTE is not a clue - that was completely unintentional).
The idea I have is that even listing out all 24 words, assuming they're in some unknown order, that creates a 24! number of possible combinations, which is 6.2e23 possible combinations. For perspective, there are 1.5e48 possible public keys, 7.9e28 private keys, and 9.2e18 grains of sand on the Earth. Needless to say, the random order seems secure enough, provided one can unrandomize the order. To do this, I've selected a fairly simple shift cipher, using a word hopefully only known to the end user - which is the weakest part of the system. However, since this is meant as a fairly secure long-term storage mechanism for people completely computer illiterate, I can't really do much bettecomplex. My hope is that if someone else finds this, they'll try forwards, backwards, every other, every 3rd, diagonal, etc, but never figure out the exact combo. After trying to bruteforce it for a couple days, they'll give up and toss it in the trash.
The cipher works by first writing down the code on a piece of paper (offline to make sure its safer). You then count out the alphabet until you get to the first word of the unscrambled wallet. In this case, my encoding word is TEST (any word is acceptable provided its fairly long - longer the better - up to 23 characters). What you do is starting with where you wrote AMATEUR, you count A, then LATER becomes B. You repeat this until you get to the letter T in TEST, which happens to be ARCTIC. This becomes the first word of the unscrambled wallet, and you cross it off (skipping over it for the remainder of the code). After you find ARCTIC, you start counting again with REPORT being A, RADAR being B, and so on, looping around until you get to the 2nd letter in the password E. This means the 2nd word of the unscrambled wallet is AMATEUR. You repeat this, looping through the list of words and password as many times as necessary. (There's got to be a word for this type of cipher, but I don't have a clue what it's called.)
All of this is stamped onto 22 GA weldable sheet metal, to be stored in a safe or somewhere dry. The idea was to create a fairly survivable long-term storage option where one of my family members could forget about this completely, find it 10 years down the road and have it still be in perfectly readable condition. Since I'm using the BIP39 implemented in the Ledger, finding a word list should be fairly straight forward in the event the metal gets bent/ripped across a word or two. The idea would be that once the user wishes to redeem their coins, this wallet would be completely abandoned for something else secure, so its a 1-time use setup.
Since I know nothing of metalworking, and I'm not the greatest at crypto, I felt like sharing the idea to inspire others, or to get advice on what I may be missing. It seems fairly straightforward, but I feel like there could be some fatal flaw that I'm completely overlooking with this. My biggest concern would be that the individual has to memorize some scramble password (which they'll have to share with me, but thats the nature of the beast and not relevant at this time), which means it could be bruteforced out, or simply forgotten. But I'd prefer a simply forgotten password than to create this "ultra secure wallet" that the first person who accidentally gets hold of it can steal everything from.

Ledger Nano S Problem, All Bitcoin Lost?

I have a ledge nano s, that I've been using for some time. Over the weekend I wanted to transfer some BTC over to it when I noticed on the app that there was an update to 1.3.1. Before updating I saved my current balance and operations history on a text file. I then reset my nano and updated it after the update I added the bitcoin app and logged in to find a 0.00 balance? Not sure if to panic or not since my coins should be safe they were there prior to the update and I did not send them anywhere.
I researched online and it seems to be happening to others. I followed the advice giving by many including resetting application data, clearing cookies and deleting and reinstalling the apps and chrome, ledger's own seen here https://ledger.zendesk.com/hc/en-us/articles/115005165349-After-the-Nano-S-update-I-can-t-find-my-coins but nothing works and my account is still at 0.00. I even went to a computer that did not have chrome and installed it on there along with the apps and nothing. The only thing I have not tried is connecting my account to a 3rd party site like Mycelium to avoid any further problems.
UPDATE: Want to thank everyone for the help. KulderZipke0 - I followed your advice and was able to recover my BTC and send it to another wallet. I've had the correct 24 words all along but for who knows what reason my nano s was not showing the money. Only after learning more on how to use this https://www.ledgerwallet.com/support/bip39-standalone.html was I able to recover my private key using the 24 words. I do not plan on using my nano anymore since it seems to be dysfunctional. If you guys have other suggestions for ways/places to store my coins let me know. Thanks Again!!!
For those of you that are having the same issue. Here is what I did. If you have your keys with you all you need to do is download this page from ledger to your desktop. https://www.ledgerwallet.com/support/bip39-standalone.html, once you do that take your computer offline. Copy your 24 words into the BIP39 Mnemonic field box, if your words are wrong it will say invalid up at the top. If they are correct you should get a QR code on the top right and a list of addresses under "Derived Addresses" look for the address you sent your coins to. Mine was the very 1st one but the list can get very long. Once you find your address copy the private key which will be the 3rd column of codes. Take that key to another wallet and recover your coins. Hope this helps.

Guide: How to redeem and sell bitcoin diamond (bcd) from ledger nano s (Segwit)

I spent two days to figure this out but I think I know how to solve this, just currently stuck and need your help! I had btc stored on a nano s segwit wallet before the fork.
Bitcoin diamond was forked from bitcoin on block #495866 (nov 24 2017) and launched the mainnet Jan 5 2018 (I think). There is currently very little information about this project and very little support on exchanges, wallets and mining. http://btcd.io
The only light wallet currently have a splitting tool is Bither for Android but they do not support Segwit. If you had your btc in a segwit wallet before the fork you can't use this method.
Otherwise follow this: https://steemit.com/bitcoin/@tiberiu/how-i-claimed-sbtc-super-bitcoin-from-my-paper-wallet Or this: https://www.reddit.com/BitcoinMarkets/comments/7oekie/guide_how_to_redeem_and_sell_all_bitcoin_fork/
You get 10 bcd for every btc and current price is 0.001 btc. That means you get $160/ forked btc which is 1% free money. Is it worth it? For me it is. You can use same method for both SBTC and BCD. Other methods can be used for BTX, BCX and BFX but have to wait for me. Need segwit support in Coinomi and/or Bither.
In my BCD case it was a bit more complicated but hopefully possible.
  1. Move btc from ledger nano to somewhere save
  2. Download the BIP39 converter (standalone version). Unplug your internet and run the html: https://github.com/iancoleman/bip39
  3. Enter your ledger 24 word mnemonic. Select BIP49 derivation path. Find your btc address that contained btc right before block 495866, copy private key. Use a block explorer: https://blockchain.info
  4. Find the tx ID that sent those btc and verify in bcd explorer if you have any bcd before you continue (click on the actual address will not work for some reason, shows empty). My tx had 3000 confirmations. http://explorer.btcd.io
  5. Now the complicated part =) You have to build bitcoin diamond core app from source because it doesn't exist yet: https://github.com/eveybcd/BitcoinDiamond
  6. I built it for windows x64 using this guide (by cloning bitcoin diamond from github instead of bitcoin when you come to that step). Took 1h.: https://github.com/bitcoin/bitcoin/blob/mastedoc/build-windows.md
  7. Actually quite cool you can run Ubuntu on Windows 10! You can build for 32 bit as well but not when you have installed dependencies for x64. The last step will copy the binaries to your windows folder: "make install DESTDIR=/mnt/c/workspace/bitcoindiamond"
  8. Run bitcoindiamond-qt in windows and let it sync with network. Took me 12h with fiber connection.
  9. Go to help and open console. If your wallet is encrypted, decrypt for 10min using: "walletpassphrase your-wallet-passphrase 600".
  10. Import old btc address as watch-only to check bcd balance. True means it will rescan the blockchain. Rescan took 1h with a decent PC (no SSD):
  11. If you see your BCD balance, now Import your btc private key into the watch-only address. No need to rescan again, thus "false".:
Ok here is where I'm stuck. I can see my balance but it's not spendable. I also tried to import private key directly (with sync) with empty core wallet but balance is still zero. It does not pick up the transaction! Anyone know how to solve this?
Rest of the guide when this is solved:
