1st. I never sold anything. Or show me my offer.

2nd. I see no point in arguing with you about adruino (sic!) codes. My grandson uses arduino in school projects, you could discuss with him.

3rd. The really cool idea is to start mining using your super algorithm. For less than a dollar, you'll make millions and revolutionize the industry! Most importantly, you don't need to learn FPGAs and true programming for that.

Could you stop posting foolishness in my thread?

This is a private development with limited disclosure. Maybe later I'll be able to give more information.
Initially, it was an open source work. Send me a PM and I'll give you some early material.

So, a long-awaited update of the calculating boards: https://ibb.co/hMxysrG

Now it contains specialized hashing chips (ASIC). It is a little more expensive than mining chips, but faster. Power consumption is reduced to ~90W per device. This solution allows to use of passive convection cooling or simple external airflow.
At the same time, bitmine chips seem to be more common.
So, both solutions are valid.

Artix7 is used on the main board. Under the heatsink.

In the WP, Satoshi proposed a core 2 duo CPU as the reference mining device. Industry has changed since then. But the core technology of bitcoin has not changed. And even if this changes, there will be compatibility with abandoned wallets that will never change in blockchain.
Think about it, we will use quantum computers and ancient keys as before generated from set of 2^160 

So a small historical digression into the ancient wallets movement*.
All wallets are created between 2009 - 2012, usually contain 50 BTC and never moved before.

2015-2020 May, 8 only.

*The list contains only virgin wallets. There are a lot more opened old wallets.
If you have a piggy bank in an ancient wallet, it is strongly recommended to transfer your BTC to a modern multisig wallet.

You didn't know what question to ask and chose this one?.. Learn this site before: https://learnmeabitcoin.com/beginners/keys_addresses  

Hint number one: blue box.

Everything is as usual. Silicon crisis, lockdown, missed deadlines. But the work continues.

Very much. About 3 orders of magnitude higher than the known solutions.
Additionally, we have developed our own chip. It should be much more efficient and fast. Or more efficient only  

Note 2.
"It takes a million years to iterate over all combinations of private keys and get the first luck!"
1EHNa6Q4Jz2uvNExL497mE43ikXhwF6kZm has a private key 0000000000000000000000000000000000000000000000000000000000000001  

One note about the "random" in generation of old wallets (until the middle of 2012).
The entire cluster below belonged to one owner. The entire cluster was generated at about the same time (two months). Just look at the wallets and answer me - is this random or not?

This is being tested now. Some T9's do not want to work with our motherboard. This is a rare problem, but we want to understand why.
Don't throw your s9's, they might come in handy later 



We also ordered a special SHA-256 chip (ACIC) for a personal device. It will be much more effective in a small volume. Additionally, we are losing our dependence on Bitmain chips.
Of course, if you have an Bitmain ASIC you have the chips by default. This problem does not concern you. But for making our own devices, it is difficult to buy new chips in large quantities...

I said earlier: the data must be prepared. For example, shifted by nonce (4-byte) and some other operations. The nonce should be loaded as well (is now a part of data). A golden nonce in Bitcoin mining is a nonce which results in a hash value lower than the target. What happens if the target == 0xFFFF....FF? Right: any result will be returned.
There are several ways to generate keys. In some, you have to complete 100k SHA256 hashes (or 50k double hashes). This way allows to reduce the enumeration range, by the way.
Finally, which ASIC do you mean? There are many chips: https://en.bitcoin.it/wiki/List_of_Bitcoin_mining_ASICs
Only Bitmain has four actual chips right now. All chips are different, have different OCD paths, "some ASIC chip" does not exist.

Several photos of the current stage: https://photos.google.com/share/AF1QipP2SmhUfXw6m5VmpXNChounStt32iGRhqHsPBErKKVNhSu50osefdQrReEZ4vk1ZQ?key=TGtZM2VvcGFjaG0xYTZzT2JCR2FLYlR5aVl1Mk1R
 

A bit update. The final version of PCBs are ready and sent to me. Hopefully it arrives before christmas...
FPGAs are already received  https://ibb.co/k8BQcph
This year viscous as jelly broke all plans and schedules... 

The next one old address was opened  https://www.blockchain.com/btc/address/1Lhb1PsvzgDDzZkWRNRAPSy9Uu8xFnNRzL

I know these lists. They prompted me to get started.
If you read the original topic, you would see I'm not looking for a key for a particular wallet. I am creating a list of goals (wallets) in RAM FPGA. Then I go through either all combinations of the private key or all combinations of seed phrases (there are much fewer, plus it is possible to reduce their number due to poor entropy, but the algorithm is longer here).

The trick is that you can check the goal in RAM very quickly. You should not search balance in blockchain or something like that.

If the address does not match, this key pair and address are recorded to the rainbow table for future and we continue to work.

The second trick is the more addresses in the list, the more likely it is to find a treasure. I will quote the calculation from the original topic from 12.31.19:

Take for example the Antminer S17e (64Th), whose current profitability is 0.5 btc/year.
The device contains 144 BM1397 chips with approximately 440 Gh at each.
We’ll make the calculation for a wallet protected by seed phrase with a 12-word. The English BIP39 dictionary contains 2048 words. The old wallet is usually encrypted in English.
((2048 ^ 12) / (144 * (440^9))) / (86400 * 365) = 1939618 years it will take one ASIC to search for all the combinations.
However, if we’ll track 10,000 wallets, then 1939618/10000 = 194 years to search for at least one match. And even if we have 100 ASICs, it turns out 2 years to search for at least one match (based on average luck).

For 2 years, these same 100 ASICs will get 2*100*0.5 = 100 bitcoins. Provided there are no changes in the network’s hashrate and the power of ASICs (NO).

These calculations are very simplified, but they show the order of numbers. And this proves the possibility of finding treasures with the usual farm's power.


Finding keys is not illegal. Then you can announce that the key for the wallet XXXX is found and ask the owner to withdraw coins. If he does not respond, it is regarded as a treasure and can be legalized accordingly IMHO.

My algorithm only searches for wallets starting with 1. Withdraw to a more modern wallet will completely protect coins.

And do not forget that Bitcoin is constantly evolving. There is a huge difference to find by 12 words or by 24, for HD or no e.g. I proceed from the assumption that the old wallet is encoded with no more than 12 words in English (or not using seed at all) and this reduces the complexity of the search to an acceptable level. For the latest wallets, this does not work and requires much more power...

The control board has enough resources to handle additional boards. The problem can only be in the electrical load of the interface. The total stray capacitance/inductance can be an invisible problem. Resistors suppress transient, but do not solve the gain problem.

Remember to carefully remove the flux from the solder points. The transient oscillation is already characteristic of these wires, but an active flux can take away a significant part of the hashrate.

For more than 9 months I have been developing a treasure hunter that will allow to return lost bitcoins in abandoned wallets. https://bitcointalk.org/index.php?topic=5213781.msg53484243#msg53484243
I do not design a cracker! It will not be able to crack modern wallets (created after 2012), old abandoned wallets only (containing up to 60% of coins, by the way) using their flaws.
Initially, it was a individual device using mining chips as a coprocessor(s) for a number of operations. This can significantly reduce the cost of the device compared to a fully FPGA solution.
However, in just a few days many popular ASICs (T9/S9 etc.) will become scrap. These are millions of free co-processors. Design a control board that can turn them into "seed-pick" seems like a good idea.

I would like to know the opinion of the community, will such a control board for the resurrection of bitmain scrap be interesting for ASIC's owners?

PS. A little about the reliability of wallets, millions years of searching and similar nonsense. Both in mining and in hunting, luck is at the basis. Finding a block using one ASIC is also difficult like finding a treasure with my device. The pool is effective in both cases.
