The most common way is to create the public address, compressed or uncompressed from a hex value, through the elliptic curve, hashing and so on. Please check this awesome web to see the whole process and with different options to start: link And if you like to check python code to see the whole process: here

If I get your code and use "e41b45e722251672c01a28e4fada590471fea09f90d13b143033ed3a1107ef49" as secret hex value AKA secret private key... then I get result: "12sF1DbBbPaoNYrs28Qm7waiCcAVoF93Nn" which is uncompressed public address. Check my script, it is more extended, but with a copule of imports for an educational point of view, to ...

No, it's not known, and information like that generally won't be publicly released. Bitcoin addresses aren't generally publicly associated with the real-life identities of their owners. I would expect a company like Tesla to have the bulk of their cryptocurrency assets stored in institutional custody regardless, for liability and regulatory reasons.

The default bitcoind wallet can handle thousands (and more) addresses and monitor them. Using the JSON-RPC, built-ins like walletnotify you should be able to build your own solution with the stack of your choice. 3rd parties is not the right approach, you'll quickly reach limits that require you to pay, so at that point you might as well spin up VPS and run ...

If you like third-part services, coinbase commerce is a good solution for this. They provide you a webhook, then when the user sends a payment to that address, they send a request to you.

As the others mentioned, the short answer is no, but from a WIF(Wallet import format) key you can determine if the address is compressed or not by checking the last byte if it is 0x01.

would it be safest to double check Yes but the difference in safety, although not exactly zero, is approximately zero. is it true that when there is a collision of address, both that person's private key and mine can move this bitcoin amount to else where Yes. Statistically that will not happen in any timespan you or I can properly comprehend. See related ...

Typically there's a seed which is displayed as a sequence of 12-24 words that is used to derive addresses/private keys in different chains. Different coins use different derivation paths which are hardcoded in the wallet so even if two coins use the same address format the generated addresses will be different.

When transacting Bitcoin, especially large amounts, you should verify the amount in Bitcoin terms. So if it was worth 2.25 Bitcoin at the time, verify that with him. That you agree on the amount in terms of bitcoin. You can see the transaction hash or transaction ID in your wallet interface to see how much was sent and where it went to. You can also check ...

No, you should not reuse addresses/treat them as a "mini-account". You should create a new one for every transaction and not re-use old addresses. Your wallet software will generally handle this automatically for you -- just remember to request a new receive address each time you receive new bitcoin, and it should give you a new address that you ...

Bitcoin addresses are essentially just large random numbers. So there's nothing to destroy or reassign - it's just a number. When you "create" a new address, what you're really doing is just picking two random numbers (that are cryptographically linked to each other) called a "private key" and a "public key". The public key is ...

Looking at the address you provided in a block explorer(OXT Explorer) 12aAEnfc6192cm4KLfV5eY13jYRqy684Ym it seems your exchange has been reusing that address quite a bit since December to now and has not really cut down on using it. I do not think they have retired the address and it is definitely still under their control. Is there an official network ...

What happens to old bitcoin addresses? I've read that they never get destroyed, but do they get reassigned? Bitcoin addresses are not reused or reassigned to anybody under any circumstances. The story is I sent some bitcoin to an exchange using an address I've used with them before, but then found out that they had just retired/stopped using that address. ...

I thought one safe way to keep a bitcoin "cold" and safe is to not show its address ever to the public. Cold storage = Private keys offline So somehow, that new address has to be "public" because it is in the blockchain and anybody can see it? So how would it be possible to have an address and be able to deposit some bitcoin into it ...

No, bitcoin addresses are not analogous to email addresses. A bitcoin address should be used only once, for important privacy reasons. If you re-use addresses, it is very bad for your privacy, and for the privacy of those you transact with. If you only use one address, then anyone watching the network will be able to know your entire financial history, if ...

is it as simple as, we can have different email addresses: Yes and no. Mostly no. You can, and normally should, create a new receiving address every time you receive money. You could, but normally shouldn't, create a new email address every time you want to receive an email message. A street address identifies a specific place. An email address identifies ...

There is no relation at all between the two addresses, except that they're owned by the same person/wallet. At the protocol level, "change" does not exist. It's just another output (with a corresponding address), indistinguishable from normal "payment" outputs. It is your wallet that's creating it: it needs a place to send the remainder ...

It doesn't interact with the "original address". It's just another address in the wallet. The wallet keeps track of all of its addresses, receiving and change.
