Bitcoin / Development & Technical Discussion / Re: Taproot proposal

on: May 15, 2021, 05:02:57 AM

Quote from: Charles-Tim on May 14, 2021, 10:54:28 PM Quote from: fxsniper on May 14, 2021, 03:31:29 AM Did Taproot decrease lower the fees? I think bitcoin now still high fee, if Taproot make fee to low is will better and very great to use often Just as ETFbitcoin explained, it depends. You can try to make use of the transaction size or weight tools calculator to calculate legacy, nested segwit, native segwit and taproot transaction fee, you can also make use of the public key per input and signature per input to calculate P2SH multisig transactions. If used correctly, you will be able to know the differences in vbytes of each which will determine how transaction fee can be. I do not have to tell you how legacy address transaction fee will be almost twice that of native segwit addresses and as native segwit transactions have the lowest fee for now, so I will be comparing native segwit transactions with that of taproot. If you check the transaction vsizes or vbytes of both native segwit and taproot, they are almost the same, but segwit is slightly lower which can be very insignificant. Which means for transaction that require 1 public key, the transaction fee will be almost the same for both native segwit and taproot transactions. But taproot make use of schnorr signature to make multisig transactions indistinguishable from transactions that require just only 1 public key (normal bitcoin transactions). Multisig transaction fee is higher than normal single wallet transactions, the higher the number of public key required in a transaction, the higher the transaction fee. If segwit transaction is low, but the more the the public key still required for a transaction, the higher the fee, but the fee will be much lower if compared to legacy addresses, but taproot makes the multisig transactions indistinguishable by making use of key aggregation in which the transaction will look like single payment wallet. Which means, increase in the number of public key needed in a transaction still will require the same amount of transaction fee as that of single payment wallet. Which means taproot reduces the fee of multisig wallets, and making its transaction indistinguishable from other Bitcoin transactions. Thank you yes, I use legacy address , that make fee feel high if use segwit addresses send, when sent will get lower fee right? and in case if use segwit addresses for receive , that will help sender to paid fee lower too or not?

problem on ML.NET dataset like a random no pattern training with 1 million dataset result very low accuracy at 0.0001% it not works I will try on keras 5 layer and 256 NN possible get result same neural networks may be work only on dataset have pattern, NN can find pattern but Secp256k1 or elliptic curve like a random

sample python script create dataset for neural networks

this script just for testing (test on ml.net)
for use need to upgrade and fix

you need to modify to fit as you use

my test on ml.net use binary to 1 and 0 get result better than number (Dec)

Can I count on anything or wasting my time? I see there are a lot of owners here for 4x3090, etc. You're probably not going to find an address with a large search range using a single 660Ti or even four GPUs. What's the ideal speed to find an address, small and large search range? no idea for now now speed up to you GPU or use multiple GPU I still use gtx 1050 low end gpu same try use function save work for continue work on large range or split small range and works finish each small job everything have cost (There is nothing free in the world ) try use GPU on cloud service. for now new GPU and second hand out of stock on market (include some low end GPU 4GB too)

Quote from: NotATether on May 14, 2021, 05:30:07 AM Again, we don't need large sophisticated neural networks, small ones will do. Though at this point you're making more of an empirical test of already used pubkeys since the Y polarity of the entire public key space converges to 50%. if do small one, neural networks for who know about neural networks. you can do with you Nvidia CUDA GPU. you know already to do. but still not yet have sample code on github for try and testing but for who don't know must about neural networks try AutoML Tables by google cloud https://cloud.google.com/automl-tables just upload dataset to server and training, that easy to use without no coding (other service both Microsoft Azure AutoML and Amazon AWS SageMaker have Automatic neural networks service same)

Quote from: SimpleMan on May 12, 2021, 07:50:35 PM But going over the discussion here I am of the impression that there is much more you need than just a state-of-the-art computer. Is this puzzle to be solved just based on luck or an element of luck or could it be solved based on pure logic? No, I think no logic can solve this puzzle becuase puzzle is random so, now for puzzle that have only address no pubkey you can do two way one is scan it all key or do random bruteforce not yet have other way can do for now

Quote from: NotATether on May 13, 2021, 01:43:12 PM We don't need all that powerful hardware, because we're not trying to guess the range of the Y point, we are only trying to guess whether it is positive or negative. For such an analysis you only need a few hundred thousand public keys and I wouldn't be surprised if you could run such a simulation on a single laptop. yes, use mathematical is smart way and no need to use powerful hardware like ECC calculate fast Did we need to create new algorithm to this this problem? or it is already have it? use neural networks is require high power of hardware (and high power software too)

No, do not pay attention to fxsniper's post. The puzzles are in the bits/keyspace related to the amount. Like you said, #64 (.64 BTC) is in the 64 bit range: 8000000000000000:FFFFFFFFFFFFFFFF sorry I use wrong word communication key is on range puzzle I mean you need to scan by use kangaroo jump too all area on keyspace but it is too wide if need to focus on key position (no way to do) it have only random keyspace on keyspace to scan, may be it is wrong way to do this yep, forget that I said help to not confused see all puzzle that solve already that tell to know key is on bits/keyspace

Quote from: WanderingPhilospher on May 14, 2021, 12:43:26 AM What are you talking about that the best method is to bruteforce? Do you still not understand how much faster Kangaroo is versus bruteforce/bitcrack?? Kangaroo the best is fast better than bitcrack and other medthod now most I use is Kangaroo but puzzle have pubkey leave only 9 address, and other 78 puzzle no pubkey when solve all pubkey puzzle out, most puzzle leave no pubkey may be use bitcrack if not have other method can solve Quote from: WanderingPhilospher on May 14, 2021, 12:43:26 AM There is no random keyspace; the keyspace is known. I mean random to small keyspace on that keyspace for scan Quote from: WanderingPhilospher on May 14, 2021, 12:43:26 AM What you are looking for is some quick way to find #120 with one GTX 1050 card...it doesn't exist. But instead of running tests and trying this and that, start on #120; work on it when you can. yes, it doesn't exist no way to calculate reverse, all method still using random method

Quote from: unclevito on May 13, 2021, 07:23:28 PM Is there any way to calculate the probable keyspace range of an address? Looking at the puzzle page the only correlation seems to be the balance. How was the keyspace range determined? No. I looking to way can calculate or can focus to keyspace nearly key but not found the way now you can only random keyspace and hop to lucky best method is bruteforce

How can use neural networks dataset? do you have more detail ? how to use classification? how to deal with large number? neural networks require to some large search support it can not do alone one person or small team I think we can not do it (you only one alone or you team 2-5 person) project neural networks risk to fail 100% no body to try it (who do it fail not tell us to know) nobody try one may be know result not easy possible only keras 5 layer and perceptron 256 or 512 can not do this job it can not normal neural networks to do this job must be very complex neural networks do this easy you can try maximum layer keras can do what is dataset to use input? output? input may be convert to binary and each column is one bit neural networks not understand character must be convert to digit or only 1 and 0 (one-hot encode data) problem Y point is 256 bit is very large number not easy to put to dataset problem most AI. result have answer short is 1 and 0 or limited digit number of possibility may be need to develop AI. 256 AI. for each bit may be need to use maximum neural networks layer may be require minimum to level same or high more than OpenAI GPT-3 how many AI.? I guest over 256 AI. by one Ai. for one bit coalition or may be 256*256 = 65,536 AI for do it how many layer? I guess over 48 layer may be (sample) 48-layer, 1600-hidden, 25-heads, 1558M parameters 24-layer, 2048-hidden, 16-heads, 1.3B parameters. 32-layer, 2560-hidden, 20-heads, 2.7B parameters. BERT use 168M parameters GPT-2 is with 1.5 billion parameters full-sized GPT-3 has 175 billion parameters so possible minimum require will be 175 billion parameters as research can do for now some idea using deep learning to train use deep reinforcement learning (must be better than AlphaGo) use NLP/MLM to translate (modify to special use) modify BIRT to works modify GPT-2 to works use generative deep learning to train one ai generate and one verify problem may be need to require training over a year result possible to get very low accurate rate if can do possible to get only just close up number on range not correct number I believe some AI. search do some research about blockchain not easy project require large fund to support what research want to do blockchain is great project freedom without control need tp be upgrade to very stronger research need to be do first before some one do it and use at wrong way I think may be natural networks possible can find found vulnerability need to fix it layer reference see https://huggingface.co/transformers/pretrained_models.html DeepMind A.I. unit lost $649 million (so how many budget to use for this ) other, you need hardware like Nvidia A100 over 1000 GPU or NVIDIA DGX A100 x 100 (or NVIDIA DGX POD) see hardware for training https://en.wikipedia.org/wiki/AlphaGo no body create project natural networks like this on GitHub can not find sample project try start project one and open to forked to extend update found other project on this forum post https://github.com/btc-room101/bitcoin-rnn

Quote from: WanderingPhilospher on May 11, 2021, 12:56:22 PM Still don't understand....are you saying that Kangaroo can't solve #120? It can, with enough GPUs or time or both. If you only have 1 GPU maybe BSGS (CPU) is better for you. Because you can split the range without impact and you will know if key is in split range, 100% I mean if I search one search from my laptop from 2119-2120 at year may be not found key puzzle #120 from my laptop I try BSGS many time, it eat my RAM 32GB and like it freeze , not work only low end laptop I will try again may be I config wrong Quote from: WanderingPhilospher on May 11, 2021, 12:56:22 PM Quote Did kangaroo.exe use same calculate from python script tame=wild = key No, as I have already explained, Td - Wd + Beginning Range = key Thank you I got it
