Do btc blocks have private keys?

[release]

This may seem like a weird question but I was reading on a Facebook post about Bitcoin block private keys.

Firstly I didn't ever think that Bitcoin blocks had private keys.

If blocks do have private keys what is the purpose and what could be done if someone knows a block key?

Edit: also does this mean that a block has a public key?

[Robertshon]

There is no relation between block and private keys.

But i can explain litlle about private key and public key
You know that you need a wallet to store your virtual coins. And just like a bank account, it has a unique address. It looks somewhat like this(15WrztREKezKUyfSrBwKAnNhq2k7Pnhp5U), depending on the cryptocurrency. It seems like a completely randomly generated a string of letters and numbers but in reality, there is a bit more going on. The first thing you need to know is how these
are created. Anyone can create a new wallet by generating a public and private key pair with a certain algorithm.In the case of Bitcoin or Ethereum that is via an elliptical curve digital signature algorithm.

That’s quite a mouthful, but the take away here is that the algorithm will spit out a private key and an associated public key. These keys are mathematically linked to each other. You can take the private key and derive the public key from it. But you cannot take the public key and turn it into the private one.

 These two keys serve a different purpose. The public key will become your wallet’s address, kind of like your bank account number. public keys can be shared with everyone And the private key is your way of proving that you are the owner of the wallet and thus that you can spend the money inside of it. Private keys must be kept to yourself.

It’s only limited by how fast your computer can generate key pairs. However, nobody will know about the existence of your wallet until it receives some coins.

Thanks for the crypto 101 lesson. Are you trying to boost post count? Your answer isn't relevant

I too wouldn't mind knowing this, I thought about it when I spotted this Block for sale in the Collectibles section.

That is interesting it's a physical block lol so he's selling private key to a block? I know that private key to the genesis block can control the entire blockchain. Their isn't much info about it. If the priv key has a nonce which it does it must have a private key but it's weird because it doesn't seem to have a public key on the curve. There are 2^256 priv keys and only 2^160 addresses does that leave priv keys for blocks or am I reading too much into lol

That "block" is the physical representation of the private key containing the miner's reward plus fees for Block number mentioned. Those physical collectibles have their private keys laser-etched and with a hologram covering it. So if you peel it off, this reveals the private key which you can use to claim the "virgin" BTC which was mined in that old block.
This also means that it'll have a bunch of forked coins including 25 BCH, 25 BTG etc etc.

If i understand correctly, OPs question is whether the bitcoin blocks that are viewable on blockchain explorers contain the private key (in some form). The answer is clearly No. Also, Blocks don't have private keys. They have block headers and the all the transaction IDs.

I know that private key to the genesis block can control the entire blockchain.

WTF are you talking about? Nothing can control the ENTIRE blockchain my friend? Not the genesis block, not even Satoshi's private keys.

Ah, I see, so that miner basically only used one address/key for that block reward then assigned it to the physical collectible.

No. You can't even spend the block rewards from the genesis blocks.

Private keys do not have a nonce.

Blocks do not have private keys and blocks also do not have a public key. The main thing that uses a private-public key pair are your addresses, P2PKH, P2WPKH, etc.

this discussion turns out to be a little complicated.
If possible I will ask something, it means Minner is someone who assembles a PC to break a "block", gets a private key and then claims bitcoin as a reward, is that right?

if yes, it means we only need a supported device to do this, can you help me with this problem?

People going in different directions. Your crazy if you think genesis keys don't control the chain. You can make any changes and implement new features mint new coins if you hold genesis keys.

They don't. If you think they do, please provide evidence as to how this address (1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa) can do anything other than spending the coins which are not from the genesis block.

Unless you have a working example of a genesis key, this is only a a fictional phrase invented for price manipulation

Google search Bitcoin genesis key I didn't make it up. When you create an alt coin you can have genesis block key which gives control tithe chain. I know I have done it 15 times. It's legit its not debatable

It is clear that Bitcoin does not work the way you think it works.  I don't know what altcoins you've created, or what that altcoin code allows you to do with keys, however:

• Bitcoin Blocks do not have Private keys OR Public Keys
• Each Bitcoin Block DOES have a generation (aka coinbase) transaction, that transaction may, or may not have one or more private keys.
• Having any private keys to an address in a generation transaction allows you to spend any bitcoins still associated with that address EXCEPT in the case of the genesis block.
• In Bitcoin, there are NO keys that allow anyone to "control the chain". That's just straight-up nonsense.
• It is possible to have a nonce, without any keys. Every Bitcoin block has a single nonce that is used to create a unique HASH but is NOT used for any key (public or private).
• The only value used in generating an ECDSA signature that might be called a nonce is the k value.  However, this is typically just called the k value and not usually referred to as a nonce.

You are spewing a lot of nonsense, and asking questions that don't make any sense at all.  It is clear that you need to understand the basics of Bitcoin better before you work on asking detailed questions about the technical details of Bitcoin's implementation.

Geez someone woke up on the wrong side of the bed this morning. No need to take it personally. The question dies make sense. I asked if Bitcoin blocks have private keys. It is clear to a certain extent they do. When creating an altcoin base on bitcoin you generate a genius block private key which controls that chain. I assume it's the same for Bitcoin

No need to take it personally.

Nah, I don't ever take ANYTHING on this forum personally.  However, sometimes a person (such as yourself) will simply refuse to accept knowledge from those (such as ranochigo) that know what they are talking about. In those cases, it might be necessary to be a bit more direct and dismissive to get them to pay attention.

The question dies make sense. I asked if Bitcoin blocks have private keys. It is clear to a certain extent they do.

That's really a stretch.  There are private keys that are associated with the public key hashes used in transactions, and there are transactions in blocks.  If that means (to you) that blocks "have private keys", then you are stretching the concept of "having a private key" a lot farther than the average person.  Beyond that, there are no private keys associated with blocks.

When creating an altcoin base on bitcoin you generate a genius block private key which controls that chain.

I find this surprising, and I suspect that you are misunderstanding the altcoin, but since I pretty much ignore anything having anything to do with the thousands of scamcoin altcoins out there, I'm willing to accept that there probably are some such that the coin provides the users absolutely zero protection beyond trusting the coin's creator.

I assume it's the same for Bitcoin

It is not.

If the alt-coin is based on Bitcoin then it will follow Bitcoin's data structures. In bitcoin, the only thing to "control" is a user's address and wallet using your private keys to sign transactions. Transactions only transfer UTXOs and don't change anything in a historic block. Protocol changes ("control that chain") means changes to the consensus rules. Those generally require an upgrade of the client you are running as well as what the majority is running.

I think you are talking about Ethereum based coins. There you have the concept of contracts that can be over-written by the developer that deploys them to change to whatever they want.

What is a "genesis block private key", what is it used for, and how is it generated? What exactly do you mean by "controls that chain"?

Not not tokens. Coins based on bitcoin
