Im running bitcoin on a Mac. How can I use a custom .conf file? On linux I cause parameters like -conf right?
I pasted the .conf file into Application Support/bitcoin but I need to let the app somehow know that I want to apply the .conf file to it.

Any advice?

Hello, everybody!

I am new to this forum (this is my first post), although relativelly informed about the bitcoin, blockchain, altocins and fintech. That's why I apologise if I didn't post this thread in the right part of the forum. If any admin wants to move it to another place, please let me know, so I can check the replies.

My problem to solve is:

I have 4 (or more) bitcoin wallets: w1, w2, w3, w4.
I control w1, which means I have both public and private keys, but I haven't the private keys from w2, w3 and w4.

What I search is an app or a program, script, that when somebody sends bitcoin to my w1 that I control, automatically to be made payments to w2, w3 and w4, and for each to be able to adjust the % sent.

Example:
if I receive 100 bitcoin to w1, automatically to be sent the payments to:
- 15% to w2; This can represent for example the AVT (added value tax)
- 19% to w3 (which can represent another tax or a commission that I owe to 1 person for that transaction);
- 25.89% to w4.

Of course, I want to be able to add as many wallets that I own, and for each to automatically send payments to as many public addresses that I don't control, and to each to be able to adjust the commission that I want the automatic payments to be sent.

Is there any solution like this on the market?
If not, can this be programed? If yes, where can I find the professionals who can do it and how much would it cost aproximatelly?

I also leave my email stud6analyt@gmail.com in case somebody want to contact me directly.

Thank you all very much for reading me and helping me with any suggestion about this!

As for the ratio I knoe that this ratio could not be. There just ann average chance that one address could have 2^96 private keys.
I asked "how many" because this guy wrote that he had such keys, but didnot want to give the example and did not say the reason why he cuuld not tell:

Considering the code and implementation of the blockchain technology, which altcoin do you think has the most differences compared to bitcoin? Please explain these differences and include a link to the "documentation" of the coin if possible. I'll try to research the coin and reply back with my findings.

Things I don't exactly consider as differences: Using different hash function, mining algorithm, asymmetric cryptography (different curve, different signature scheme), and obviously: different supply, block time, block size,...

Just run a full node of whatever coin you want to accept and use the json-rpc interface... generate a new address for each client and keep a database that connects the client to the address...

Coins using the bitcoin codebase use more or less the same json rpc commands, coding something like this should be fairly simple... Altough i would advise to let a senior dev assist you... A simple mistake can have serious consequences, altough, as long as you keep your wallet locked, it should be fairly safe.

I am running  Bitcoin_qt   018.1.  windows
There is a file named "wallet" but it is not directly readable. How can I see the amount of bitcoins in my wallet?

We have seen many people complaining that they had mistakenly sent bitcoins or any cryptocurrency to an address which they didn't want to.
Many times hackers hack other's wallets and steal their cryptocurrencies.

Everybody knows what an OTP is. It adds an extra layer of security in your payments.

What if we developed a wallet and integrated the OTP feature in it which basically when approved broadcasts the transaction on the blockchain ?
In my opinion this would add a layer of security. OTP doesn't need to be centralized and hence it won't break the decentralization part of bitcoin (but obviously a centralized wallet can still break it)

I'm looking for programmers so they can
generate ERC20 token wallet

I was trying to pay a Bitpay invoice. I opened the invoice in Electrum app and tried to pay it. I contacted the Bitpay support with this address but they say it doesn't belong to them.

I was trying to pay a Bitpay.com invoice and opened the invoice in Electrum-BTC desktop wallet. I don't know how, but somehow that transaction got sent to and invalid address bc1qcygs9dl4pqw6atc4yqudrzd76p3r9cp6xp2kny
The transaction should be returned if the address is not even a valid bitcoin address (it has non-supported characters right?) but it appears that the transaction is already confirmed
Transaction id 1cdc45c6f92430d021f387af6564353cb90281da4ee8e1e9721387ad05874c45
Please help me out there

P.S
 The wallet prompted me to install an update before sending the transaction and I'm pretty sure it was official electrum-btc website.

I want to buy from codono.com their scripts but I found no reviews did anyone buy from them.

They did give me these payments they received with reviews.

It looks real can anyone confirm.

Not it was not the firewall

here is the log >> https://pastebin.com/J32B8wdA

All long line breaks are those point where the daemon is hanged and we restarted

Hi Guys,

Want your opinion on what multi crypto payment processor you would recommend to accept crypto payments.
We are developing a crypto gambling platform. The internal currency Will be Btc but we want to accept multiple currencies as deposit option.
So please let us know which processor/ gateway you would suggest

Thx

I'm working on a small project for a while now and I still can't get my head around this topic. In my project users would have an internal balance for bitcoin and some other altcoins. They would be given a unique deposit address during registration and they would be able to deposit any amount of currency at any given moment, which would appear in their internal balance after 6 confirmations. They would also be able to enter their own address and withdraw funds. The same kind of system every cryptocurrency exchange has in place. I genuinely can not find any info on the internet on how to implement these systems, every single payment processor is invoice based.

It's pretty possible to implement something like this by yourself with the official Bitcoin Core and Full Node Softwares for bitcoin's clones, like litecoin and dogecoin. There has to be a mechanism in place that would be catching transactions on the network. However, I'm concerned about bitcoin core's walletnotify. I was told it creates a lot of memory problems for the machine. ZMQ, on the other hand, catches all the transactions, even the irrelevant ones.

So how do all of these cryptocurrency exchanges operate? Do they simply write these wrappers around the node software that collects needed data and saves in the database? Some of them have hundreds of coins! Do they have an instance of every coin running on their servers and separate software around these instances? Is there a common name for such payment processing? Is there any more information that I can look at?

Guys, I need a software for a full CryptoCurrency Exchange including following options:

Initiating different markets for different currency pairs.
Getting buy/sell order for each market with the capability of Limit,Market,Stop
Showing order books for buy and sell queues.
Processing market orders and excluding exchange costs.
Deposit and withdraw of Currencies.
Show Balance and history of each currency.
Integrating with special bank system. (Bank Mellat) Document will be provided.
Manually entering and confirming  incoming drafts to bank accounts.
List of withdrawal orders including 3 items:(Paya,Satna,Mellat) and processing them by operator.
API for each market infos
All function from user side should be acceble through API.
Report for deposit and withdrawals of each user and all users.
Report for history of activity of each user on each market and all users on each market.
Verifying process for each user including registering bank account, ID verification, uploading pictures, Mobile number and telephone number verification.
Option for Manually verifying each user.
Troll box for chatting users.
Information board for users.
Showing graphical view for market depth and market history for one different periods(Daily, weekly, monthly)
Daily Reports fro all trades for each market.
Showing open orders and option to cancel them.
Message Box for each user and option to send message to each user and all users.
Option to activate Google authenticator for 2 factor authentication.
Option to generate API KEY for each user.
Changing password and profile information by user.
Showing logs for user logins.

Please update me, if you can do this, or you did this before.
The programming language is preferred to be Python.

Thanks,
