Bitcoin uses cryptographic key "pairs"
There is a public address and a private key (long string of letters and numbers for each)
A simple way to understand it is a username(public address) and a password to allow sending money from that address(Private key do not share)
That is basically the gist right there.
Remember Bitcoin is a network so there are many many options from hundreds of vendors and open source projects to simplify the process and access the Bitcoin for you. These are called wallets. They manage your key pairs for you. To back up a wallet you write down a 24 word seed phrase(private do not share) this will allow you the leisure of not storing every single address you own and let the wallet store them for you. If your wallet is destroyed or lost this seed phrase is how you recover your coins. Only use trusted wallets that this sub can recommend you, use the search bar.
You can get Bitcoin by earning it. ORRR trading from an exchange. Depending on your country and local laws this could be various different places. But generally Kraken, Gemini, and Binance are the most popular.
Remember however, if your Bitcoin is not in your wallet or you do not have the key pairs it is in, then you do not own the Bitcoin. Keeping your Bitcoin on an exchange or another 3rd party is highly risky and vulnerable to hacks or the exchange just straight up stealing your funds or even government stealing your funds.
So: Not your keys not your coins.
Plus: Don't use Bitcoin "Doublers" or anyone claiming if you send them bitcoin they will send you back double.
Plus: Don't buy altcoins, ICOs, or get involved with defi.

Question: How many public keys per private key / address?

I'm curious about the structure of the relationship(s) between Bitcoin addresses, public keys, and private keys.
My previous assumption was that from each private key would derive only one public key, and one address via nested RIPEMD160 and SHA256 one-way hash functions.
But this is the case, I'm wondering why I have found the same "scriptPubKey" value showing up in transactions originating from different addresses.
Put differently: Shouldn't transactions originating from different addresses have different "scriptPubKey" values?

How to convert my public key to a bitcoin address using python?

Hello,
I'm playing with a little python script to understand how bip32 works.
I can successfully generate my public key using bip32 python module.
pub_key = bip32.get_pubkey_from_path("m/44'/0'/0'/0/0") print(binascii.hexlify(pub_key))
How can I convert my public key to a Bitcoin address ? Should I implement https://en.bitcoin.it/wiki/Technical_background_of_version_1_Bitcoin_addresses ?
Or can I use another python module for this?

Public address support without weakening ring signatures?

Public addresses are useful for organizations/users who want to make it visible what happens in their account. Might be useful, for instance, for some non-profit organizations. Still, Monero anonymity is great because it gives anonymity to other users who send to this public address or receive from it. Currently, Monero supports public addresses in such a way that the owner provides the view key. However, if someone makes their address public in this way, doesn't it mean that all ring signatures that pick this address to the ring are weaker? If many users/organizations use public addresses and these addresses have lots of transactions, these public addresses might be used in ring signatures quite often. This may weaken Monero ring signatures significantly. Could Monero support "public" addresses which are similar to Bitcoin addresses (public key + private key) and these addresses are never used in ring signatures? Would this make sense or have I misunderstood something?
EDIT: Apparently this question doesn't make sense because the view key doesn't let one to see the outgoing transactions: https://getmonero.org/resources/user-guides/view_only.html

Satoshi Nakamoto built in defenses against quantum computing attacks - If you use one Bitcoin address one time, then your ECDSA public key is only ever revealed at the one time that you spend bitcoins sent to each address. A quantum computer would need to be to break your key in that short time.

WOW !This is difference of VTA with other coins : VirtaCoin addresses are similar to Bitcoin addresses and can be used to send and receive Bitcoins as well.

Well, VirtaCoin addresses are similar to Bitcoin addresses and can be used to send and receive Bitcoins as well. You can also send VirtaCoins to a Bitcoin address and Bitcoins to a VirtaCoin address. A single VirtaCoin or Bitcoin address can as well be used to separately manage balances of both crypto-currencies. VirtaCoin is the first and only scrypt-based coin to do all this. Here is an example of a VirtaCoin address: 1HgtXf8HnWVYrGoSAkCyAWwAMHp7gUW2gR As you can see it starts with a "1", just like most Bitcoin addresses. VirtaCoins can be sent to Bitcoin addresses that begin with a "3" such those provided by GreenAddress. "3" Bitcoin addresses can be used to send Bitcoins to VirtaCoin addresses as well. Using Private Keys To Manage Dual Balances You will need to know the private key of your VirtaCoin or Bitcoin address to be able to view and manage the opposite balance of the wallet that originally created the address, meaning for a VirtaCoin address created with VirtaCoin Core you'll need the private key in order to see any bitcoins sent to that VirtaCoin address in a Bitcoin wallet. Exchanges and most online wallet providers don't normally give you the private keys of your VirtaCoin or Bitcoin address so its best to use addresses created from wallets that you have total control of, such as desktop or mobile wallets. Desktop wallets such as MultiBit can be used to export the private keys to a file on your computer while mobile apps such as Bitcoin Paper Wallet can generate addresses with private keys. To use your VirtaCoin address as a Bitcoin address in your Bitcoin Wallet simply import the private key of your VirtaCoin address into your wallet. The popular Blockchain Wallet works well with importing your VirtaCoin address and can reveal your VirtaCoin/Bitcoin address (public key) if you only know your private key. Similarly you can use the private key of your Bitcoin address to import the address into the VirtaCoin Core wallet. Just follow these steps, specifically on importing a private key into VirtaCoin Core. Please remember to backup your wallet before importing another address into VirtaCoin Core.

[Hiring] Need a software application that can pull every Bitcoin address out of huge text files.

I would like to hire a software engineer who is capable of creating a software program for me that can do what is described in the title and below.
I understand that Bitcoin addresses have certain characteristics, although I have no idea what they are (check sum?), and I doubt I have the capacity to learn. I need someone who already understands these properties and has the ability to create a software program that can go through a fairly large text file (500+ KB, thousands of addresses), and create an output file that contains only all of the valid Bitcoin addresses (public keys) from the source file.
It has to be able to read addresses in situations where there are no spaces or line breaks between the valid address and other, unrelated characters. It should pick up valid address only (of any character length), but not strings of characters of the same length that aren't valid btc addresses.
So for example if the input file looks something like this:
blah blah blahblah(BITCOIN ADDRESS 1)blah blah blah 
(BITCOIN ADDRESS 2) (BITCOIN ADDRESS 3)
:(BITCOIN ADDRESS 4)3333393939j33 
the output file should look like this:
(BITCOIN ADDRESS 1)
(BITCOIN ADDRESS 2)
(BITCOIN ADDRESS 3)
(BITCOIN ADDRESS 4)
I hope that makes sense. If anything isn't clear I'll be happy to provide further clarification.
If you are capable of and interested in doing this for me, please either post your contact details here or send me a PM. I would appreciated it if you could give me some sort of estimate of the price you will charge for this job.
Payment in Bitcoin of course.

Mt. Gox, an unlikely explanation: RAM error, corrupted private key

This is an extremely unlikely explanation, but I thought I'd throw it out there:
An error with the RAM on the system Mark used to create the cold wallet resulted in a corrupted private key. Desktop systems don't use ECC RAM and it would be unwise to make the cold wallet address on one of his servers.
If everything was held in a single cold wallet, this is a (unlikely) possibility.
Don't think RAM errors are a big deal?
quoting wikipedia -
"However, as discussed in the article on ECC memory, errors, while not everyday events, are not negligibly infrequent. Even in the absence of manufacturing defects, naturally occurring radiation causes random errors; tests on Google's very many servers found that memory errors were not rare events, and that the incidence of memory errors and the range of error rates across different DIMMs were much higher than previously reported."
Don't think anyone would be lazy enough to keep all coins in a single cold wallet address?
dooglus, a very well respected member of the bitcoin community, keeps all of just-dice's coins in this single cold wallet address (39,000 BTC):
https://blockchain.info/address/14o7zMMUJkG6De24r3JkJ6USgChq7iWF86
(Actually, I think he uses an offline laptop, and maybe that is what Mark used, too)
Ways around this problem: You would have to re-import the private key, and verify bitcoin-qt gave you the same Bitcoin address ("public key") the second time around. Otherwise you have no idea if your private key is any good - until you import it to cash out. There is no checksum in the private key.
The above scenario is extremely unlikely and I think Mark found a different way to screw up.

Hi,
We would like to update everyone with some our plan for going live. We have been speaking together latley about payment processing and have decided that we will be delaying our launch to work on native Bitcoin Multi Signature payments.
We believe that the only way to be able to feel secure using a market place is with forced multi layer encryption, forced encrypted communication and the knowledge that it is not possible to have your bitcoins stolen from you. To understand how this will work, we first must give a basic explanation of how bitcoin works.
Every address does not actually hold real funds, rather your private key proves that you own "outputs" on the chain. Each of these outputs is a previous transaction and your wallet GUI shows you the sum of your unspent outputs.
For example, when you send a transaction, your wallet does the following:
* Get's all unspent outputs belonging to you * If the amount you are sending is more than the biggest output available, it continues adding these outputs as inputs till it has enough to cover the total you are sending, otherwise it will get the smallest output that covers the amount you are sending and use that as an input. * It creates an output of the amount you are sending and the wallet you are sending too. * If the total amount of all the inputs is more than you are sending, it creates another output called a "change wallet" which belongs to you and recieves whatever is left over (E.G, total output size is 30, you send 20, change is 10). * It signs this transaction with the private keys of the outputs that is is claiming and broadcasts it amongst its peers. 
Bitcoin supports multi signature addresses which is a unique bitcoin address actually created by using 3 public keys of bitcoin addresses and any funds sent must use private keys - in this case, 2 - of the original 3 public keys to sign the transaction, thus preventing any 1 party from claiming these inputs on their own.
Our idea is that when a customer places an order, they will input their enforced pgp encrypted shipping address and a bitcoin signing address and will then be given a new 3 way multi sig address generated from a mediator (Us), vendor and their own address. Any funds sent to this address will require 2 of the 3 parties to sign before they are able to be spent.
* For refunds, we will create a transaction with 2 outputs vendor and customer, splitting the original amount between both outputs and allow the vendor or customer to sign and broadcast. * Before an order is accepted and shipped by a vendor you are able to cancel the order and we will provide a signed transaction allowing you to void the contract. * If the vendor is offline for 7 days, all disputes created will include a signed transaction enabling a customer to cancel the contract. * If the order is finalized, we will provide a signed transaction sending 1% of the amount to an emengency wallet and the rest to the vendor. The customer and vendor could send eachother encrypted messages to get around this fee but we hope that they won't do that. This 1% will be sent to a wallet that will be controlled by the community and be for emergency situations. 
This means that in the case of an emergency, alternative temporary forums could be put up by community members to facilitate the disbursment of in-escrow payments and prevent the loss of any bitcoins at all. We can't steal your bitcoins, the vendor can't steal your bitcoins and no malicous party can steal your bitcoins. Users would be paid a small bounty for finalizing their payments. This would be funded by the 1% fee and managed by trusted community members.
This also means that we do not need to be tumbling coins and it will also be extremly difficult to analyze payments between vendor and customer. Each payment will look like any other multi signature payment on the network (Though there are not many multi signature payments currently as it is a new feature) and have no affiliation with any previous Marketplace transaction. We hope that P2SH becomes more standard as that would allow us to create more complex rules that would create an even more decentralized platform.
We feel the typical flow for a user would be: * Use a Bitcoin Broker to buy bitcoins via cash deposits and send funds to blockchain.info wallet * Send funds to trusted external bitcoin tumbler (e.g, bitcoingfog) to wash for a day or two * Purchase items and input a bitcoin address public key and send funds from tumbler to wallet given * Recieve items, click finalize, review.
The worst case flow would stop at clicking finalize and would continue more like: * Community forums setup, vendor creates thread to get money for shipped items * Users will sign the transactions for the vendor and recieve a payout from the emergency wallet managed by vendors (also escrow protected) * If a user did not recieve, they would be eligible to request a refund from the vendor but they would not recieve any bounty and the vendor can refuse or the user could withold the funds preventing them ever being by anyone.
We will not be charging vendors a set fee per order but we hope that vendors pay our requested fee % of their own accord, this may change in the future if it proves unviable.
We hope that this gets people excited about what is to come and allows our customers and vendors to feel a lot more safe. We hope to roll this out in the next few weeks and we will be connecting our payment servers to the Bitcoin Testnet to allow people to send real test bitcoins on the Testnet - https://en.bitcoin.it/wiki/Testnet.
