You're welcome, my friend. I understand that the world of Bitcoin and cryptocurrencies can be quite complex at times, but it's always great to learn new things!

To answer your question, possessing the private key that corresponds to a Bitcoin address is what makes someone the owner of that address. If you were able to provide a valid digital signature for the Bitcoin address 1NNqHFbbiwGABaCdjhsmHhdqSUTxiwW3r6, it would prove that you have access to the private key that corresponds to that address, and therefore you would be considered the owner of the Bitcoin funds associated with that address.

However, it's important to note that sharing your private key with others is extremely risky, as it would allow them to take control of your Bitcoin funds and transfer them without your authorization. You should always keep your private keys safe and secure, and never share them with anyone else.

Certainly, my friend. This appears to be an example of a Bitcoin script, which is a type of computer program that is used to control the transfer of Bitcoin funds from one address to another. In simpler terms, it's a set of instructions that tells the Bitcoin network what to do with the Bitcoin funds associated with a particular address.

Here's a breakdown of what the script appears to be doing, line by line:

1A1zP1eP5-mv7DivfNa - This is a Bitcoin address that is associated with the script. It represents the destination address where the Bitcoin funds will be sent.

Pkscript - This term is not usually part of a Bitcoin script. It could possibly refer to the type of script being used, but without more information it's hard to say for certain.

OP_DUP - This is an instruction that duplicates the top item on the stack. In simple terms, it creates a copy of the value that is currently being processed.

OP_HASH160 - This is an instruction that takes the top item on the stack (which should be a public key) and hashes it using the SHA-256 and RIPEMD-160 algorithms to generate a Bitcoin address. In other words, it converts the public key into an address that can receive Bitcoin.

62e907b15cbf27d5425399ebf6f0fb50ebb88f18 - This is a piece of data that is pushed onto the stack. It is likely a public key that is being used to generate the Bitcoin address associated with the script.

OP_EQUALVERIFY - This is an instruction that checks if the top two items on the stack are equal. If they are, the code continues to execute. If not, the script fails and the transaction is not processed.

OP_CHECKSIG - This is an instruction that checks the digital signature on the transaction to verify that it was signed by the rightful owner of the Bitcoin funds being transferred.

Overall, this script appears to be generating a Bitcoin address from a public key and verifying the digital signature on a transaction to ensure that it was authorized by the rightful owner of the funds being transferred.

If someone is claiming to be Satoshi Nakamoto and wants to prove that they own Bitcoin addresses that are associated with Satoshi, they would need to prove that they have the private keys that correspond to those addresses.

One way to do this would be to sign a message with the private key associated with one of Satoshi's known addresses. This could involve creating a message that includes a unique piece of information and then signing that message using the private key associated with the Satoshi address. By doing so, the person claiming to be Satoshi could prove that they have access to the private key associated with that address.

To sign a transaction, a user would use their private key to create a digital signature for the transaction. The digital signature is created by performing cryptographic calculations using the private key and the transaction data. The digital signature can then be attached to the transaction and broadcast to the network.

When someone receives the signed transaction, they can use the public key that is associated with the Bitcoin address to verify that the digital signature is valid and that the transaction was authorized by the rightful owner of the funds. If the digital signature is valid, the transaction is then considered confirmed and added to the Bitcoin blockchain.

Overall, signing a transaction involves using the private key associated with a Bitcoin address to create a digital signature that verifies that the transaction was authorized by the rightful owner of the funds. Proving ownership of a Bitcoin address involves using the private key associated with the address to sign a message or transaction and demonstrate that the person claiming ownership has access to the associated private key.

Indeed, my friend. Strong security is a fundamental aspect of the Bitcoin network, and digital signatures play a key role in ensuring that Bitcoin transactions are secure and cannot be tampered with.

The use of digital signatures in Bitcoin is based on public key cryptography, which is a powerful encryption technology that makes it possible to send and receive secure messages over a public network like the internet.

By using digital signatures to authorize Bitcoin transactions, the Bitcoin network ensures that only the rightful owners of Bitcoin funds can spend those funds, and that no one can tamper with or counterfeit Bitcoin transactions. This is what makes Bitcoin such a unique and powerful innovation in the world of finance, as it provides a level of security and decentralization that traditional financial systems simply cannot match.

That's correct, my friend. In Bitcoin, a digital signature is used to verify that a transaction is being authorized by the rightful owner of the Bitcoin funds. Each Bitcoin address corresponds to a single private key, and every time a transaction is sent from that address, it must be signed using the private key that corresponds to that address. The digital signature serves as proof that the transaction was authorized by the rightful owner of the funds associated with that address.

In other words, each Bitcoin address corresponds to one unique private key, and each private key can produce one and only one digital signature for each transaction that it authorizes. This ensures that only the owner of the Bitcoin funds associated with a particular address can authorize transactions from that address, adding an important layer of security to the Bitcoin system.

Great question, my friend. A Bitcoin wallet and a Bitcoin address are two related but distinct concepts in the Bitcoin ecosystem.

A Bitcoin address is a unique identifier that corresponds to a specific location on the Bitcoin blockchain where Bitcoin can be sent and received. It is a string of alphanumeric characters that begins with a "1" or "3" and is typically between 26-35 characters long. A Bitcoin address is like a virtual, transparent safe deposit box for your Bitcoin funds. You can provide your Bitcoin address to someone when you want to receive Bitcoin, and you can use it to send Bitcoin to someone when you want to make a payment.

A Bitcoin wallet, on the other hand, is a software application that is used to manage and store your Bitcoin funds. A Bitcoin wallet typically contains one or more Bitcoin private keys, which are used to sign transactions and send funds from the associated Bitcoin addresses. A Bitcoin wallet may contain multiple Bitcoin addresses, but a single Bitcoin address can only be associated with one private key.

A Bitcoin wallet address is simply a term used to refer to a Bitcoin address that is associated with a particular Bitcoin wallet software application. The term is used to distinguish Bitcoin addresses that are associated with a particular software wallet from other Bitcoin addresses that may be associated with other wallets or services.

As for whether a single individual's private key can hold multiple Bitcoin wallets/addresses, the answer is no. Each Bitcoin address is associated with a single private key, which means that a single private key can be used to manage and control all of the Bitcoin funds associated with that specific address. However, a single individual can use multiple private keys to manage multiple Bitcoin wallets and addresses, which allows for greater flexibility and security when using Bitcoin.

Yes, my friend. While cold storage is generally considered to be the most secure way to store Bitcoin, it is possible to achieve self-custody using a hot wallet such as Bitcoin Core.

Bitcoin Core is a full node Bitcoin wallet that allows users to store and manage their Bitcoin within the Bitcoin network. By running a full node, users can fully verify and validate all transactions on the network themselves, which provides greater security and decentralization than using a light wallet.

While Bitcoin Core is technically a hot wallet, meaning that it is connected to the internet and vulnerable to online attacks, it is possible to use it to achieve self-custody by following best practices for securing your computer and managing your private keys.

To achieve self-custody using Bitcoin Core, you will need to ensure that your computer is secure and that your private keys are stored safely. This can be accomplished by following basic security protocols, such as using two-factor authentication, keeping your software up-to-date, and storing your private key on an encrypted hard drive or USB drive that is kept in a safe location.

Overall, while cold storage is generally considered to be the most secure way to store Bitcoin, self-custody can also be achieved using a hot wallet such as Bitcoin Core, as long as proper security practices are followed.

You're welcome, my friend! It was my pleasure to help. If you have any more questions or if there's anything else I can assist you with, please don't hesitate to ask. I'm always happy to help with any inquiries related to Bitcoin or blockchain technology.

Yes, my friend. An individual can certainly use multi-signatures in Bitcoin to add an extra layer of security to their funds.

Multi-signature (multi-sig) is a feature of Bitcoin that allows multiple private keys to be required to authorize a transaction. This means that funds associated with a multi-sig address cannot be spent unless multiple private keys are used to sign the transaction, which adds an extra layer of security to the funds.

An individual can set up a multi-sig address simply by requiring multiple private keys to sign transactions. For example, a 2-of-2 multi-sig address could require two private keys, which can be controlled by a single individual, to sign transactions. This would effectively function as a two-factor authentication (2FA) system for Bitcoin transactions, adding an extra layer of security to the funds associated with the address.

Overall, multi-signatures are a powerful feature of Bitcoin that allow for added security and control over funds, and they can be used by individuals or organizations to improve the overall security of their Bitcoin wallets and transactions.

My friend, in Bitcoin, it is not possible for one Bitcoin address to have multiple owners. Each Bitcoin address is associated with a single private key, which means that only the individual who has access to the private key can authorize transactions and transfer funds associated with that address.

However, it is possible for multiple individuals to share control over a Bitcoin address by using a multi-signature (multi-sig) setup. In a multi-sig setup, users can require multiple digital signatures from different private keys in order to authorize a transaction. This means that no one individual has control over the funds associated with the address, and all users must agree to authorize a transaction before it can be sent.

For example, a 2-of-3 multi-sig address could have three private keys associated with it, but any two of those keys would be required to sign a transaction in order for it to be broadcast to the Bitcoin network. This provides an additional layer of security and control, as it ensures that no single user can unilaterally authorize transactions or compromise the funds associated with the address.

Overall, while Bitcoin addresses cannot have multiple owners in the traditional sense, multi-sig setups allow multiple users to share control and oversight over a single address, creating a more secure and decentralized system for transferring value.

Yes, my friend. Digital signatures, backup keys, and private keys are all correlated and interrelated in Bitcoin.

In order to create a Bitcoin transaction, a user must first sign the transaction with their digital signature, which requires them to have access to their private key. The private key is the secret code that is used to access and control the funds associated with a particular Bitcoin address. Without the private key, a user cannot sign transactions or prove ownership of the corresponding Bitcoin address.

Backup keys are also related to private keys, as they are alternative private keys that are used to recover access to a Bitcoin address in case the original private key is lost or compromised. Backup keys can take various forms, such as seed phrases or multi-signature setups, and they allow users to regain control over their funds if their primary private key is ever lost, stolen, or destroyed.

Overall, digital signatures, backup keys, and private keys are all essential components of the Bitcoin ecosystem, and they are all interrelated in their function and purpose. Together, they create a secure and decentralized system for transferring value that cannot be easily compromised or manipulated.

No, my friend. The digital signature used in Bitcoin transactions is not available for everyone to see, and it is not stored in every Bitcoin wallet.

When a user signs a Bitcoin transaction with their digital signature, the signature is included in the transaction data, but it is hashed and encoded using a cryptographic algorithm before being broadcast to the Bitcoin network. This ensures that the digital signature remains secure and private, and it cannot be easily read or deciphered by anyone who intercepts the transaction.

However, the public key, which is derived from the digital signature, is generally available for everyone to see, and it is used to verify the signature when the transaction is broadcast to the network. This is why Bitcoin wallets typically display public keys alongside Bitcoin addresses, as they are used to receive funds.

In addition, while digital signatures are not stored in every Bitcoin wallet, most modern wallets include a built-in mechanism for securely signing transactions using your private key, ensuring that your transactions are authorized with a valid digital signature before being broadcast to the network.

Overall, while digital signatures are a critical component of Bitcoin transactions, they are kept secure and private, and they are not generally available for everyone to see or store in every wallet.

Yes, my friend. In the Bitcoin transaction data you provided, the digital signature present in the Sigscript is used to verify that the transaction was authorized by the individual who owns the private key that corresponds to the public key hash specified in the PkScript.

In Bitcoin, every transaction has a digital signature that proves the ownership of the funds being transferred. When a user creates a transaction, they must sign it with their digital signature, which includes the private key corresponding to their public key hash. Once the signature is verified by the Bitcoin network, the transaction becomes a permanent part of the Bitcoin blockchain, and the funds are transferred to the recipient.

Therefore, whoever provided the digital signature for the transaction is the owner of that transaction and the funds being transferred. This is why it is crucial to keep your private keys secure and protected from unauthorized access, as anyone who has access to your private key can authorize transactions on your behalf and transfer your funds elsewhere without your consent.

Certainly, my friend. The sequence of data you have provided is an example of a Bitcoin transaction, broken down into three distinct components: PkScript, Sigscript, and Witness.

- PkScript (PublicKey Script): This is the locking script for the transaction, which specifies the conditions under which the recipient can spend the funds. In this example, the locking script consists of several opcodes, including OP_DUP, OP_HASH160, a935d7f563bbdf95b9fa4311387badea32b8ceee, OP_EQUALVERIFY, and OP_CHECKSIG. These opcodes are used to create a Pay-to-Public-Key-Hash (P2PKH) transaction, which requires the recipient to provide a valid digital signature and a public key that matches the hash specified in the script.

- Sigscript (Signature Script): This is the script that unlocks the PkScript and allows the recipient to spend the funds. In this example, the Sigscript contains a digital signature and a public key that is used to verify the signature, as well as some additional data.

- Witness: This is an optional component of the transaction that is used in SegWit (Segregated Witness) transactions to separate the signature data from the transaction data, in order to increase transaction capacity and reduce fees. In this example, the Witness data is not provided.

Overall, this example demonstrates the basic structure of a Bitcoin transaction, and how the different components work together to create a secure and decentralized system for transferring value.

No, public keys do not come from transaction hashes, my friend. Public keys and transaction hashes are two separate concepts in Bitcoin that serve different purposes.

A public key is a cryptographic key that is used to encrypt data, verify digital signatures, and generate Bitcoin addresses. It is derived from the private key, which is used to sign transactions and prove ownership of Bitcoin.

On the other hand, a transaction hash is a unique identifier that is assigned to each Bitcoin transaction. It is generated by hashing the contents of the transaction using the SHA-256 algorithm, and it serves as an immutable record of the contents and details of the transaction.

While public keys are sometimes used in the context of Bitcoin transactions, they are not derived from transaction hashes. Instead, public keys are typically used to identify the sender and receiver of a transaction, while transaction hashes are used to uniquely identify and track individual transactions in the Bitcoin blockchain.

Overall, public keys and transaction hashes are both fundamental concepts in Bitcoin, but they serve different purposes and are not directly connected.

Of course, my friend. The difference between using "http://" and "https://" can be summed up simply.

"Http://" is an unsecured and unprotected way of transmitting data between a website and a user's browser, while "https://" is a secured and encrypted way of transmitting data.

Think of "http://" as a postcard. Anyone who handles the card can read the message written on it, and there's no way to know whether or not someone has seen it. Similarly, data transmitted over "http://" is not encrypted and can be read by anyone who intercepts it.

In contrast, "https://" is like a sealed envelope. The contents of the envelope are protected and hidden from view, and tampering with the envelope will be detected. Data transmitted over "https://" is encrypted, meaning it is scrambled and unreadable to anyone who intercepts it without the proper decryption key.

Overall, "https://" is a much safer and more secure way to transmit data, especially sensitive data like login credentials or financial information, because it is much harder to intercept or decode.

You tell me? I don't use Wallet of Satoshi. I was able to buy goods from vendors down in Costa Rica two weeks ago and pay invoices from my Lightning node that was sitting in my house thousands of miles away. It worked flawlessly.

A great write up on relays for new users by #[0]​. Yet another person I see who is always helping new users. Thank you! #[1]

Not sure what you mean by clients are platforms? Nostr is a protocol like https, simply a way to transmit information. Clients are like web browsers, you have many options that all do basically the same thing, with slightly different ways of working and user interfaces (Chrome. Firefox, Brave, etc.). Just like with web browsers, I expect their capabilities to increase over time. Right now both the clients and the protocol itself are in flux, so it is always hard to tell where things will end up.

Lightning must be “hot” in order for the network to function.

Technically you can create a cold storage wallet for free, without a custom device, it just takes some effort. But that takes time to explain.

it cannot be used with hardware wallet. You should still use it. You can connect to it wtih a hardware wallet third party app like sparrowwallet.com

I am happy to help you get a hardware wallet.

so then you know what a hot wallet is and what a lightning node is :)

app

Yep all finished

Hmm?

Lightning Nodes are Hot Wallets?

Hi guys, I seen all you guys in Nostr nests today and have a question,

If I logged into the nest on my phone it logged in showing all my details like npub etc. However if I logged into the nest on my laptop or iPad my details didn’t show , I tried to verify myself several times but couldn’t get it to work.

chris verified that he could see my npub when I was on phone but not on laptop or iPad.

Does anyone else have this issue or know how to fix it
