What are Keys & Addresses in Bitcoin?

Zcash

Bitcoin and most cryptocurrencies expose your entire payment history to the public. Zcash is the first open, permissionless cryptocurrency that can fully protect the privacy of transactions using zero-knowledge cryptography.

What if I send Bitcoins to an incorrect public key?

I am just curious about it. What happens if I send bitcoins to an invented public key? Will I get a “rejected transaction” message or something like that?

Lmao... so they just openly perjured themselves by admitting they have the private keys to some of the stolen Bitcoin...? good job Ira. This is exactly what CSW has been waiting for. Now he'll drop proof of his ownership with public documents. HONEYPOT.

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?

Theoretically, if there was a vulnerability making private keys derivable from public keys would Bitcoin be doomed?

I'm trying to understand how Bitcoin would respond. Would it find a new way or would that be impossible? In the event that someone could break elliptical curve private public key encryption.

Identity Verification on the Tangle

ID verification using the tangle
Using the tangle and the bitcoin signature scheme, I created a proof of concept for verifying identity and reducing the need for continuous document uploads to prove your identity everytime you want to do something in finance.

Introduction
The limitations of the iota tangle are that signed zero value transactions require MAM channels, and valid addresses change frequently. So using Bitcoin addresses which are known, and familiar, verifiers ('Trusted entities') of identity can sign on the authenticity of documents.

How it works
An entity with a known bitcoin address belonging to a trusted entity can review documentation, and sign as to their contents. Think of banks, insurance companies even governments.
Use case: John Smith wants to open a loan at the bank, but as part of the banks KYC requirements they need to review some documents to prove he is indeed John Smith. So he submits his passport, and the bank verifies this. The bank can now create a transaction, proving that John Smith is indeed John Smith, by simply creating a zero value transaction on the tangle.
This zero value transaction is signed with the private key of the bank, and contains all of John's information in text format. This example it is only his name 'John Smith'. The bank has verified his information by cross checking his passport, and shares with him the public transaction hash and their public key (Bitcoin address).
John later goes to an crypto exchange which once again is requesting his passport. He now only needs to provide the exchange with his Name, the TX hash and the Bitcoin address that verified his information. If the exchange trusts the Banks KYC procedures, they can approve his information without needing his documents to be uploaded again. Thus saving the need to store it!
Expanding
This concept will probably die here, but this could go much further the type of information that can be sent in tx bundles, could include address, name, ssn, and maritial status. Perhaps even compressed and digested ID photos could also be uploaded, so everything to his identity could be kept in the hands of those he trusts.
Conclusion
There will always be a need for banks and governments to verify your identity, but hopefully this can assist in reducing the burden on small entities, while John maintains his privacy through the trust of smaller firms on larger ones.

What is bitcoin going to do to prevent quantum computers from generating private keys from public keys?

From what i understand Bitcoin uses a form of RSA to generate public keys and private keys. So when quantum computers gain enough qubits its going to be possible to extract your private key from your public key. Are there currently any proposals for changes to prevent this.
Im just interested in bitcoin so please correct me if im wrong about something

Bitcoin Private Key Finder (Android & PC) How to Generate a Private Key from a Bitcoin watch only address What are Bitcoin Public keys and Private keys? George Levy - What are Bitcoin Public and Private Keys? Bitcoin Private and Public Keys Explained Simply

Public Key Cryptography in Bitcoin Public Key Cryptography is an essential part of Bitcoin’s protocol and is used in several places to ensure the integrity of messages created in the protocol. Wallet creation and signing of transactions, which are the core components of any currency rely heavily on public key cryptography. How is the public key hash used in Bitcoin?. When you want to receive bitcoins, you give someone your public key hash.They will then put this in to the locking code of a transaction output.. This creates a P2PKH locking script.. Then, when you want to unlock these bitcoins (to send them to someone in a new transaction), you just put your original public key along with a digital signature in to This will display the area for your Bitcoin Public Key. Toward the top, it will show that you are in the Bitcoin section of your wallet. You’ll want to double check that you are on your Bitcoin. We’ll just need the Public Key, so you can click the button that says Copy Address. Then, you can simply send it. In my earlier guide on Bitcoin wallets, I have used two terms extensively- Private Address (or key) and Public Address (or key). These keys are what makes Bitcoin the safest and most widely used cryptocurrency. To understand private keys and public keys, let us look at an example. Consider a mailbox where you receive your physical mail. In bitcoin we call these a public key and a private key. Here are your account details. Welcome to Bitcoin. However, this “account number” is awkwardly long number. So to make life easier we create a condensed version of this public key, and we call it our address. You’ll see how hideous the public key is in a moment.
