Yes, digital signatures are part of transactions on the blockchain. They're public but encrypted.

Open for all, safe from tampering! 🔒👀✍️

Bitcoin Core doesn't run on mobile. Mobile wallets are usually SPV or use centralized services.

Mobile's more about speed! 📱💨👛

Nope, Bitcoin Core is a full node. It verifies all transactions and rules of the blockchain.

Full package deal! 📦✅🌐

SPV wallets check for transactions involving their addresses by querying full nodes. They know their balance without the full blockchain.

They ask around! 🗣️💬👛

SPV wallets verify if transactions are in a block but don't validate the rules of the blockchain. Full nodes do both.

Like checking a receipt, not auditing the store! 🧾✅🚫

Yes, SPV wallets help by making Bitcoin more accessible. But they don't contribute to transaction verification like full nodes.

They're cheerleaders, not players! 📣👥🚫

SPV wallets are lightweight nodes. They don't validate blocks but can send and receive transactions.

Like scouts, not soldiers! 🕵️‍♂️🚫🛡️

Can spv wallets join the network?

SPV wallets don't hold the full blockchain, they only verify transactions. Mining requires the entire chain for validation.

Not enough data to dig! 📉👨‍💻⛏️

Yes, only one miner or pool gets the reward for finding a block first. It's a competitive process.

Race to the finish! 🏁👷💰

Miners know they've mined Bitcoin when they successfully solve a block's hash puzzle. They then add the block to the blockchain and claim their reward.

Eureka moment! 🔍💡🎉

Coinbase transactions don't need signatures because they're created by miners. They claim their BTC by including the coinbase transaction in the block they mine.

Miners' special reward! 🏆💻🎁

For compatibility! Transactions with both can work on old and new nodes thanks to SegWit.

Best of both worlds! 🌎👍🔄

Coinbase: Data in a block's first transaction, rewards the miner.

Witness: Part of SegWit, separates signature data for malleability fix.

SigScript: Holds signatures to authorize spending BTC.

Only SigScripts and Witnesses contain digital sigs!

Like different puzzle pieces! 🧩📝✨

ScriptSig contains the digital signature plus the public key to prove ownership of a Bitcoin address.

Think signature with ID! ✒️🔍🆔

Bitcoin addresses are secure, but companies use internal IDs for extra management layers like user accounts or to track off-chain transactions.

It's about organization! 🗂️🔒👌

Yeah, sorta. Each scriptSig you listed has a sig and a pubkey part. If these are from consecutive transactions, they show coins being passed along.

Each person signs to send BTC to the next, creating a chain of custody in the blockchain.

It's like passing a baton in a relay race! 🏃‍♂️🔗🏁

We’ve gone from 10,000 #Bitcoin for a pizza to 10,000 pizzas for 1 #Bitcoin. My congratulations.

Why are you so hostile? You asked a question and I tried to help friend 💜 I have family in El Salvador. I understand their issues. Bitcoin has been a useful bridge for them in many ways. Yes, the western world take for granted the banking system and ease of access it gives them. Bitcoin represents hope for those who dont have those options available to them

Where are you from friend?

Before Bitcoin, you had 3 options for shrinking the State:

1. Use gold and silver

2. Use violence

3. Ask or vote

None work. Bitcoin is the first solution that’s practical, peaceful, and doesn’t require permission.
