Help needed to decode keys

HI,
Another year and I'm still plugging away at these old mining keys.

The wallet is circa 2013, 1CAS address, Base58 (P2PKH) format. I have found a file named "bitcoin-wallet-keys-2011-10-08" which is from the very early versions of the Andreas Schildbach Bitcoin wallet for Android. I remember using a version that didn't even have a pin lock on it, it was that early!

I believe this version was pre-256 and was hashed using MD5, I have managed to decrypt this file with OpenSSL, but now the file is some weird, non-human-readable format, a binary wallet file rather than plain WIF keys??

I've been messing about with protobuf and bitcoinj wallet tool, but can't find a way to extract such old keys, so many things have changed since then!

Any pointers would be greatly appreciated

Goosebumps and thrill in this thread  Grin

OP, don't mind this too much, maybe I am just a dirty minded person who likes to over think, I don't know why my mind thinks that you may not be the owner of that wallet?

Maybe you need the owner has some bitcoin and the only that belongs to the owner was this phone? Hope that's not the case? Because first thing after creating a bitcoin wallet comes the recovery seed, you can't even go the next page without verifying those words first.

So anyone, either newbie or not, who opens. A new bitcoin wallet will have to understand the importance of recovery seed at the moment, I don't know about others but something keeps telling me that this doesn't belong to you.

Are you high? Why would I make it up about a dead wallet from 13 years ago? It was 100% my wallet, you were clearly not about in those days. The Android app was less than secure, there was no lock on the app, so someone with your phone could just send your BTC to anyone they wanted and the backup was your seed just emailed to you! lol

Here is an example email I still have from the miner bot.

Which type of Samsung phone is this exactly?

Because I know when it comes to iPhones, somewhere around the iPhone 4S-5 era it was impossible to recover anything because of the way the data was stored on the device. It was basically encrypted and if you wiped it the key was destroyed and backup was not possible. It’s been years since I looked into this but this I am sure of. It’s because I wanted to sell an old iPhone and wanted to make sure my data was completely safe from the new user.

Find this out first before you spend money on a data recovery service.

Its not even a Samsung, i got it out the box today and its a Nexus 4 made by LG i think, doesnt have a memory card so must be internal storage....

The i7 has always been a multi-core processor.



Sorry auto correct put the hyphen in the wrong place, a single core-i7 is what I meant, which was indeed a quad-core processor with hyper threading,

Dave, you seem very pedantic, I'm guessing you don't have too many friends IRL....?

It's not that strange, 2013 was the oldest wallet/ backup I could find at the time and just assumed that's how far back I went.

Since '21 I have found access to older emails and reference to the payouts to this wallet from a now defunct mining pool.

I first remember mining BTC on a single-core i7 CPU, so I was about even earlier than that too.

And no, this was a different wallet that I managed to crack the encryption on and was in fact an empty wallet from 2013 incorrectly named.

I've only just found the phone and yes should have made a backup but this was 21 Aug 2011! This was so early, as I said in the OP there wasn't even any unlock security on the BTC app. There wasn't much value to protect...

I didn't even know there was 0.7btc in the wallet still.

My main question is about searching the phone, all the "recovery" software i have been looking at is looking for and sorting out certain file types, like .jpg, .mov etc as you'd probably want from a wiped phone.

I'm looking for a file that doesn't even have a file type!

I have found my old mining address which still has about 0.7btc in it...

https://www.blockchain.com/explorer/addresses/btc/1CASsBYhRAFrJkQXzw8E2di7vP6FhQyEpC?page=1

The question is, I know I was using an old Samsung phone and the Schildbach wallet, this was so early on that I still have emails from where I was asking him asking for pin unlock because I thought it was insecure!

https://play.google.com/store/apps/details?id=de.schildbach.wallet

This app used to like to backup the keys to a file called bitcoin-wallet-keys-xxx-xx-xx (xxx being the date)

The thing is I cannot locate this backup, but I do have the phone, does anyone here know of any good software to scan the phone with, the phone was wiped at some point so needs to be pretty low level kinda stuff...  Huh

Any hope of doing this or am I wasting my time?

When you say efficient technology you're not talking about BTC right???

You didn't understand what I wrote? I talked about magnetic tape and paper records, not Bitcoin. And the topic is central bank mining... I'm saying if we want efficient tech adopters, banks won't be that.

The average energy consumption for one single Bitcoin transaction in 2020 was 741 kilowatt-hours.

That's pure insanity to me... People need to stop turning a blind eye to what we are doing here, this isn't efficient, it's insane!


People need to stop looking at this blindly, ignoring cost-benefit. That is insane, I agree, to accept banks are doing what they're doing and we can't get better.


Yeah, and where has that attitude got as a species....?

You have clearly demonstrated to the contrary.  Your posts essentially amount to a grab bag of common newbie misconceptions.

My kindliest suggestion to you:  Go to Beginners & Help, and start learning.  If you make an effort to ask smart questions and you are lucky, then someone with expertise may have the patience to explain to you the basic concept of Byzantine fault tolerance, the respective rôles of miners and non-mining validating nodes, and other key points that you have shown you do not understand.  If you are very lucky, then an expert in distributed systems architecture may explain to you in detail why Satoshi didn’t just use Paxos.

(If the nodes that create the ledger can be trusted to order transactions, then I myself could easily design a Paxos-style consensus protocol with results authenticated by digital signatures.  It would use no proof-of-work—no hashrate at all!  Zero electricity spent grinding hashes!  It would be orders of magnitude more efficient than your Rube Goldberg scheme; and if the transaction-ordering nodes can really be trusted, then it would be just as secure.  Whereas if they can’t be trusted, then your scheme is totally insecure.  My design would be fault tolerant, but not Byzantine fault tolerant; of course, since you lack knowledge of this subject domain, what I just said may as well have been in Greek.  “μῆνιν ἄειδε θεὰ...”)

If you want for me to tutor you, my current consulting rate for educating arrogant dolts is 0.00875 BTC/hour.  To be clear, that is a discount quote and a time-limited offer.

HTH, HAND.

Why would you assume I need an arrogant cunt like you to teach me anything? You fking retarded child...

I've been involved in BTC since early 2013, so I understand fully how it works. All of your comments were strawman or just pure ad hominem...

What is it about forums and the way they attract such self-righteous morons? Why can't someone just have a discussion without having a superiority complex?
 
I was not making reference that mining is the diver of price, it was just a turn of phrase that both the price and the hash rate are both going to the moon! 

No one has yet given an expliantion any how over 700kwh for a transaction is in any way justifiable???

So what happens in the future.....We just continue down this path until we need more hash power than there is available electricity in the world, sure exponential growth in price is exciting but exponential growth of energy use is not...

Bitcoin will never change into a centralized system controlled by governments or anyone else, forget about it. You are wasting time by making such proposals, there's already countless centralized projects without mining, and they aren't overtaking Bitcoin anytime soon.

And Bitcoin is not wasting energy, there's no other way to have a system with these properties. All this energy ensures that Bitcoin is secure.

What you've just said there is utter BS and your attitude stinks...
There is always improvement to be made.

Explain to me how over 700kwh for a transaction is in anyway justifiable???

Given that central banks are among those slowest to adopt new and efficient technology (magnetic tape and paper documentation is still how most banks globally operate), and are guilty of the most inefficient and bloated structures and wasteful practices, I'd be very surprised if they were able to provide the most efficient energy usage were they to go into mining.

So aside from the political reasons why "CBM" won't be a cure -- they have to accept they're not even viable for consideration.

When you say efficient technology you're not talking about BTC right???

So, my first question is, if you were going to implement your idea...
How do you stop me from running mining equipment in my house in the U.S.?
How do you stop someone else from running mining equipment in their house in Spain?
How do you enforce your idea so that the Central Banks are the only miners?

If central banks want to be miners, they can already do that.  Nothing is stopping them.  But your idea isn't adding Central Banks as miners, your idea is REMOVING all other miners from the world. What are you going to do, knock on doors and inspect households and shoot anyone that is found to be in possession of mining equipment?

My second question is... How does your idea solve anything? It's still an arms race.  Each central bank will want to have MORE hash power than the other countries. This will both bring in more revenue (to offset their mining costs) AND will ensure that the enemy countries can't collude to attack transactions from allies.  As such, total amount of equipment and electricity will continue to increase.  Only now, instead of the amount of mining being self-regulated by profitability, these countries can tax their citizens and engage in mining at a loss to increase their total influence.  The will result in even MORE electricity being used than the current system.


The same way other chains do, only accept valid blocks from an approved list of nodes, You can mine if you like but you won't get any reward for it...

The idea solves this dumb race to be the first to compute a block, this is driving energy use to the moon, not just the price!

If there is a fixed number of mining farms then there is only ever XYZ amount of hash power available, this then causes a difficulty readjustment much lower to maintain the 10min/block ratio.

The community would set a reasonable hash limit to the central banks, via on-chain voting. If there is a hash limit then there won't be competitive mining, it would just be there for the pure purpose of validating and securing the blockchain.

Any future mined coins would have to be staked like ETH2.0 and any attempt at a bad acting would result in the CB deposit getting burned.

You must live under a glass bell where everything is ideal, there are no bribes, corruption, crime and bad intentions. Do you really think that central banks would play by the rules, who would set those rules at all, maybe you?


WTF are you talking about? The system is exactly the same as we have now........the same core code, the rules are already set!!! Those very same rules that stop the Russians and Chinese from colluding right now!!!!!!!!

No, it doesn't defeat the purpose at all, they would have no control over the currency, no ability to inflate it or change it in any way, because they are a single actor in the system.

How is the network being validated by over 200 CBs in some way inferior to having most of the work being done in China or the US....which is currently happening! 

You must live under a glass bell where everything is ideal, there are no bribes, corruption, crime and bad intentions. Do you really think that central banks would play by the rules, who would set those rules at all, maybe you?

The belief that CBs would play fair and not change anything is naive to say the least, because it's like saying that all the world's major powers don't cooperate on key issues - and that their influence doesn't influence others to play by the rules they set.

If BTC mining were to be managed by the central banks of countries that are members of the G20, for example - how long do you think it would take them to agree on some changes that they could definitely implement given that they control the network? You live in total delusion if you think that there is no difference between the network being controlled by those who just want to make a profit and those who are interested in some completely different things, because they have as much money as they want anyway.

The G20 can hardly agree on anything and as the name suggest are only a block of 20 countries, nowhere near what would be required to change something in the core code.

So it's ok to have most of the mining activity in one country that we in the west we don't trust.....?

How is that ANY different from having a mining operation in every single country..........? its really not, in fact it's better. It would be like the UN for money.

Currently, I don't have to trust the Chinese or Russian miners who validate my transactions, the software keeps them in check. I'm sure if I were given a choice where my tx was validated I wouldn't have those people/countries do it!   

At the end of the day, I would likely trust a central bank way more than some sketchy operation in the arse end of China, but it doesn't matter with BTC where or who does the mining. So what's the harm in letting only Central banks do the work needed to secure the network?

It would remain opensource and controlled by the people....

I can't see any downsides to what I have suggested!?
I share your sentiment about mining not really being as decentralized as some would want it to be. It needs a large investment and the people who afforded it are now big players themselves.

Even then, what you have to understand that those are essentially individuals or privately-owned entities that do not have to justify their actions for political motives. When it comes to governments, it is exclusively about gaining political mileage. They can go to any extent for that and also have the wherewithal to do what they want. Bitcoin as a philosophy tells the common man that "Here is your money, keep it safe and no institution or government, no matter how powerful, will part this from you".

That is empowering and something that we have never had. This is really an answer to all the faults of democracies. Giving common people the freedom to hold money which cannot be hurt by stupid governments. When it comes to governments, or anybody in power, they have almost always fucked up things that require agreements. Conflict resolution isn't really a forte of governments. They dilly-dally over issues for political reasons and use all kind of machinations to ensure that their side wins.




Thats why I chose the CBs because generally speaking...

Quote
Central banks are inherently non-market-based or even anti-competitive institutions. Although some are nationalized, many central banks are not government agencies, and so are often touted as being politically independent. However, even if a central bank is not legally owned by the government, its privileges are established and protected by law.

Most, if not all CBs in the west do not answer to the .GOV, they are free to act as they see fit free from political involvement.

Quote
Due to these reasons, it isn't really a good idea to have Bitcoin be controlled by a set of permissioned entities, no matter who they are or how many of them there are.

How is mining the chain "giving them control" Huh

by this same logic, we are now allowing China to control BTC........?

Yes that how I see it, it would be no different to today and would in fact be more decentralised than what we currently have with basically only 2 countries doing all the mining!

Surely that's the idea of BTC is that it's trustless!
