this is my address 15vMMXtLJ8EHEv7rxjAfNuDem9UzHcTi6a then I suppose to send sample 3QiDnqgAyXTdagGeAjjLa6DPdTiSpznj41 it say

any help :(

Required for #9 and might be a good step forward. You seem to already use compressed addresses by default.

Is this something you're interseted in doing? I'm already in way over my head trying to add Bitcoin Cash support to walkingliberty. pybitcoin doesn't have compressed public addresses nor BIP-143. electrum has BIP-143 but using that codebase looks like a nightmare.

Thank you!

Hello,

I need to create addresses on HD wallet. How can I do it?

Best regards

If I want to send a multi-multi transaction like this, but bit only supplies create_transaction method in the key.

I found that it can specify UTXOs (https://ofek.github.io/bit/guide/transactions.html#unspent), can I use this method to create a transaction from multiple addresses to multiple addresses?

I'm trying to import a pem key:

Hello

I need to find the uncompressed and compressed WIFs from a HEX key. I managed to get the compressed format using .from_hex() succesfully

In the advanced section of the documentation there's a section about Hex to WIF, I am unable to import that module and unable to get an uncompressed WIF
https://ofek.github.io/bit/guide/advanced.html

Thank you.

key.get_balance() returns string type while key.balance returns int.

How can i get Payment History via WIF (Key)?

Hi,

Great library, thanks for building it!

I was able to get to speed rather quickly and could move testnet coins around but I noticed that very often I have to wait a while for create_transaction() or send() to return without errors. In some cases I had 8 confirmations on a testnet wallet after getting some coins from a faucet and trying to move them to destinations also generated by this same library. The error I usually hit :

~/anaconda2/envs/foo/lib/python3.6/site-packages/bit/transaction.py in sanitize_tx_data(unspents, outputs, fee, leftover, combine, message, compressed)
     93 
     94     if not unspents:
---> 95         raise ValueError('Transactions must have at least one unspent.')
     96 

However calling get_unspents() clearly shows Unspents and confirmations. What's the reason for this error?

Hello
I need to create uncompressed public keys whith text.
For compressed Keys i use:
key = Key.from_int(int(sh.sha256(word.encode('utf-8')).hexdigest(),16))
wif = key.to_wif()
addr= key.address
works fine, but i need the same with uncompressed.
It's possible ??

Hello.
Is possible to generate address with text ?
for exemple:

k = Key('Hello this is my text')
print(k.address)

I have a transaction stuck in pergatory that'll never confirm, yet never seems to get out of mempool.

I'd like to sweep that wallet, but (most) of the APIs don't return those unspents. I've been thinking about how to do a Replace By Fee transaction. I figure you just take the inputs of the transaction you want, then adjust the outputs/fee accordingly and broadcast that transaction.

So to do this I think we need:

get_transaction() to get the hex of a transaction broadcast. We then need get_transaction_as_unspent() which would take the hex of a transaction and return it as an unspent. I guess a second argument would be the key, unless we just provide that in the key class that this is off of anyways.

Then finally, get_unspents_from_transaction() which would iterate through the inputs of a transaction, and build an unspent list that could then be used by send().

Does that seem about right? Not sure I want to add this in any time soon but I am curious if this seems about like the right approach.

So it'd look kind of like:

key.send(unspents=key.get_unspents_from_transaction('rbftransactionid')...)

Thanks!

Hi ofek and all,

This is by far the nicest Python Bitcoin library I've looked at.

Just curious about your rationale for setting combine as True by default. I would think that a user will never pay lower fees with combine as True and may end up paying higher.

Let's say there are six inputs of 10,000 Satoshis each. The user will make two transactions of 11,000 Satoshis.

If combined is True:

Transaction 1 takes 6 inputs for the transaction and has two outputs.

Transaction 2 takes 1 input for the transaction and has two outputs.

If combined is False:

Transaction 1 takes 2 inputs for the transaction and has two outputs.

Transaction 2 takes 2 inputs for the transaction and has two outputs.

At this point, the transaction size has been 7 inputs vs 4 inputs. combine=True logic is definitely simpler to implement, but once combine=False logic is implemented I don't see a reason to use combine=True. You can do some really clever stuff if expanding on combine=False, like matching inputs exactly if you have that opportunity, or building up the smallest possible transactions. I think in general the smaller transactions will consume the dust-like inputs which would otherwise be needlessly combined if combine=True. In the end the user will pay transaction fees now or later. It might make sense to do combine=True when mempool is abnormally low, but other than that optimization I think you can never do worse with combine=False and occasionally better.

Please correct me if I'm wrong on this. I think a lot of unspent selection nuances are ignored and are likely worthy of consideration, especially with TX fees as high as they are in BTC.

Thank you!

I'm not sure where else to ask, but I can't seem to generate a public address(for sending transactions).
According to your wiki after generating a private key via key = Key() I should be able to use the address attribute. but key.address give back the private key again and key.public_key generates something unusable (at least by a novice).

What am I doing wrong?

I needed to sweep funds from multiple addresses I own (i.e. I have their private keys) to a single address. I did not find a way to do that from the documentation so I added that functionality in my fork.

Here's a reference to my commit:
joemarct@42450a5

Usage is as follows:

from bit import PrivateKey
from bit.transaction import create_sweep_transaction
from bit.network import NetworkAPI

# Generate addresses (or import private keys)
key1 = PrivateKey()
key2 = PrivateKey()
key3 = PrivateKey()

# Sweep the funds of key1, key2 and key3 to the destination address below
destination = 'n1n2YUzwJSNueBsKE6D9kaQGrLFj3Wc3bL'
sweep_tx = create_sweep_transaction([key1, key2, key3], destination)

# Broadcast the transaction
NetworkAPI.broadcast_tx_testnet(sweep_tx)

If there is interest in having this merged here, I'll create a pull request.

I have tried running a simple code to check my testnet balance, but it isn't working.
Here is my code:

I when i run "python BTCt.py" or "python3 BTC.py" the following error is thrown:

Hello

How is the get_balance informatin retrieved? Is it getting from blobkchain.info? Is there a limit on how many times in a row you can use it?
It has returned 0 satoshis on the private keys I tried even when the computer was disconnected from the network.
Also, is it possible to get the balance of a public key/address instead of a private key?

Thanks

@bjarnemagnussen Please add yourself 😄

Fantastic repo. When I first used this, I was confused by the naming of MultiSig. I assumed the class was a MultiSig wallet, but it actually represents a single member of the MultiSig wallet right?

Would you consider a PR renaming it to MultiSigMember, or can you think of a better name?

how to get the public key hash ,and create multiple address using primary key?

Why speed of execution in console $ python -m timeit -s "from bit import Key;k=Key()" "k.address" faster than in IDLE? In IDLE 100000 take 10 sec.

from bit import Key

start_time = time.time()

i = 100000
while i >= 1:

k=Key()
k.address

i = i -1

print("--- %s seconds ---" % (time.time() - start_time))

The function estimate_tx_fee() was not edited accordingly to allow correct fee estimation for multisig keys. I just published a pull request for segwit functionality and the same holds true for segwit.

Maybe someone has any good ideas to allow estimate_tx_fee to calculate a correct fee. I will also try to work on it in the near future.

When I go to run a program based on this, I get:
Traceback (most recent call last):
File "C:\Users*\Desktop\bit-master\bitcoin2.py", line 1, in

File "C:\Users***\Desktop\bit-master\bit\format.py", line 2, in
from coincurve import *

The problem is I imported coincurve directly into my folder as well as installing it with pip. Further I tried to look for verify_sig anywhere and could not find it.

Hi,

This seems to be the only sanest python bitcoin library. Truely, great work there.

I would love to use this library but unfortunately local nodes are not supported.

Do you have any timeline to support the local nodes?

Do you need funding or donation?

Please, let me know.

Currently the MultiSig class behaves like the raw Bitcoin protocol by creating a multisignature contract ordering the public keys in the Script exactly as they were used as arguments in the initialization of MultiSig.

For Bit I think it would make much more sense to use lexicographical ordering of the public keys, so that it does not matter in which order the public keys are presented when initializing the MultiSig class (see answer to https://bitcoin.stackexchange.com/questions/39370/how-to-create-the-same-2-of-3-multisig-adresses-as-electrums-multisig-wallets).

I regret not having thought of that from the beginning. Following the implementation of P2SH multisignature, Bit has grown to a new release number and forcing lexicographical ordering may break currently used multisignature contracts created with the class MultiSig.

For simplicity of use in Bit I suggest to change the default behaviour to use lexicographical ordering, but allowing a flag to be set that disables this ordering. A code change to allow for this would be quite straight forward.

Are there any reasons against it?

I have no experience with paying to scripthashes except when it's worked automagically for me before.

In #12 it looks like the initial workins of P2SH are being added. I'm not sure how straight forward P2SH is.

But... for the time being shouldn't we throw an exception if we try to send() to an address that does not begin with 1? Are there any sideeffects to doing so?

I think I just lost a fair bit of coin not reviewing this properly. Hopefully if we add in an exception we can keep others from doing the same.

I was trying to import bit, right after installing it and getting this:

What could be a reason for this? and how to solve it?

The documentation here mentions from_hex and a way to import from WIF. But is there a way to import a key from a brainwallet? e.g. correct horse battery staple? I've just taken a quick glance at the docs and was wondering if this is possible.

I'm the author of pycoin.

The page https://github.com/ofek/bit/blob/master/docs/source/guide/intro.rst show shows pycoin as being very slow generating sec blobs. This can be sped up very significantly by setting the environment variable PYCOIN_NATIVE=openssl which will use OpenSSL for two slow functions. See also the "Too slow?" section at https://github.com/richardkiss/pycoin/blob/master/README.md

Currently the testnet wallet WALLET_FORMAT_TEST is drained (see last Travis build report). Since we return testnet coins to the address n2eMqTT929pb1RDNuqEnxdaLau1rxy3efi belonging to the faucet tpfaucet.appspot.com, I wanted to request new testnet coins from them.

However it appears that the faucet is offline (the captcha hasn't been working for some time). So maybe we should switch to another faucet and also use that new faucet's address to return testnet coins?

https://www.reddit.com/r/Bitcoin/comments/bgg5n7/stop_overpaying_fees_i_made_a_website_to_give/

https://bitcoiner.live/doc/api

Looks pretty good. I can probably get around to this but wanted to make a note here.

I think there's some weird behavior here.

The address mwRCvxvDWoHfLoXbu4CRsSr8n9DJCVPboK is the sender, and the receiver becomes mqBMNEWEcYwz9DmTACzNQpT8xgkVyoxXBK instead of 2N2ud4TqixtLTf4cpEsJTdUb1TZegQUkB2U, why it happens?

What's wrong with that? The code below gives out an error Traceback (most recent call last): File "/home/tony/Documents/DLF/Dev/1.py", line 15, in <module> NetworkAPI.broadcast_tx_testnet(tx_2) File "/home/tony/.local/lib/python3.7/site-packages/bit/network/services.py", line 533, in broadcast_tx_testnet raise ConnectionError('Transaction broadcast failed, or ' ConnectionError: Transaction broadcast failed, or Unspents were already used

from bit import MultiSigTestnet, PrivateKeyTestnet, wif_to_key
from bit.network import NetworkAPI

key1 = wif_to_key(WIF1)
key2 = wif_to_key(WIF2)

multisig1 = MultiSigTestnet(key1, {key1.public_key, key2.public_key}, 2)
multisig2 = MultiSigTestnet(key2, {key1.public_key, key2.public_key}, 2)
tx_1 = multisig1.create_transaction([('2Mxpa7jzh37ZuXKVxqnS5RLD7XCdGFrDFy1', 100000, 'satoshi')], fee=30)
tx_2 = multisig2.sign_transaction(tx_1) 
print(tx_1, tx_2)
NetworkAPI.broadcast_tx_testnet(tx_2)

I'm having issues with the Code Sample from the Documentation on balance requests.

Why does the code sample use the Testnet to get a balance of a wallet. Is there a "Mainnet" function to access the balance? I assume that the Testnet doesn't provide accurate transactions from the Blockchain, am I wrong?

Also is there a way to get the balance of an address without knowing the private key, which is also used in the code sample. Many other libraries use the wallet address as the argument to a getBalance function. Does Bit have something similar?

Code Sample In Question: key = PrivateKeyTestnet('cU6s7jckL3bZUUkb3Q2CD9vNu8F1o58K5R5a3JFtidoccMbhEGKZ')

Thanks in advance

Bitcoin mainnet and testnet addresses encode the same information/scripts, but have different prefixes to differentiate between the two networks.

Currently in Bit it is possible to e.g. spend from a mainnet address/PrivateKey but include testnet addresses in the outputs (and vice versa, and mixed cases). Bit then simply converts those testnet addresses to its mainnet equivalent in the outputs of the spending transaction.

This may lead to confusion, and I would like to discuss if maybe there should be some sanity checks in place to let the user know when a mix of mainnet and testnet addresses and private keys are used?

Hi,

Just to test your lib and how it s handle error and refuse from service use to get balance, i just executed the following code, once you reach quota limit of services API the error appear.

>>> import bit
>>> while True:
...   k = bit.Key()
...   if k.get_balance() != '0':
...     print(k.to_wif())
... 
Traceback (most recent call last):

Thanks for developing this amazing project.

I have 8250 satoshis on Testnet, and when I invoke key.send() and specify the fee, it raised an error, because the fee parameter is satoshis/byte, not just fee itself.

How can I specify the fee and send all the bitcoins to another address?

I create a key before, but not store WIF, can I find it now ?

can anyone confirm wither bit supports multisig address generation and spending?
