🧵 Day 4/7 – What you’re really signing – Inside a Bitcoin transaction. You’ve seen the button. “Send Bitcoin.”. But what actually happens when you click it?. Let’s unpack the moment you approve the transfer. #JustBen #DYOR #BackToBitcoin.1/11🧵 👇

Cashback for swaps. For me that sounds good. Wallchain partners with protocols to redistribute fees to users. It's margin sharing (nice !). Presenting more bit by bit.

Tomorrow:. → what happened to your own bitcoin?. And following, what is the future of Bitcoin?. Spoiler:.Bitcoin has no “plan B.”.#JustBen #BackToBitcoin.11/11🧵.

In the end, you don’t send Bitcoin like an email. You sign a transaction, pay a fee, and let the network do the rest. It’s called crypto because every transaction is secured by cryptography, math that locks each message like a sealed envelope no one can forge. 10/11🧵.

🔹 No identity?. You didn’t use your name. You didn’t ask anyone. You just signed with a private key.and updated a public ledger. That’s how Bitcoin works. No gatekeepers. Just verification. 9/11🧵.

🔹 What happens next?. When your transaction is mined, it becomes part of the blockchain. From there, it can’t be changed. The Bitcoin is now spendable.by the person holding the right key.to the address you sent it to. 8/11🧵.

🔹 How much is the fee?. There’s no fixed rate. Miners choose which transactions to include first. If you offer a higher fee, yours gets picked faster. If the network is busy, the fees go up. 7/11🧵.

🔹 Why do you pay a fee?. You’re not paying the person you send BTC to. You’re paying the miners to include your transaction in a block. The fee is based on size (in bytes), not the amount you send. 6/11🧵.

🔹 Where it goes. Once you sign the transaction, it enters a waiting area. That’s called the mempool. You can see it : . Miners will soon pick it up and include it in the next block.if your fee is good enough. 5/11🧵.

🔹 The role of the address. The recipient doesn’t have to approve. You just point to their public address, like an inbox. If you get it wrong. Once sent, there’s no undo button. No “cancel payment.”. 4/11🧵.

🔹 You don’t sign with your name. You sign with your private key. It’s a digital signature that proves the coins are yours to move. No one sees your name. But the signature matches the wallet. And, that’s enough. 3/11🧵.

🔹 A transaction = a message. A Bitcoin transaction is a message you send to the network. It says:."I want to move this value, from this chunk, to this address.". The network checks:.→ Are the funds there?.→ Do you have the right key?.2/11🧵.

What if your BTC could do more… without leaving Bitcoin? (no wrapped).@PortaltoBitcoin you lock BTC and borrow elsewhere. Not your keys, not your coins? .Here, your keys stay on Bitcoin. That's User oriented.That answer a real need : don't touch the BTC.

Wallchain connects with your wallet. Then, it detects swaps before you make them. auto-routing through partners. This will get you the best rate and cashback. So better handle less slippage failed. Are we transforming Web3 into TradFi ?🧐.

🔹 What makes it special?. Bitcoin doesn’t store your coins. It stores rules, and a record of changes. You don’t rely on a company to hold your value. You use a protocol anyone can check.and no one can secretly rewrite. Tomorrow:.→ How to read a Bitcoin transaction.10/10🧵.

🔹 Can someone fake the notebook?. Not really. If one computer tries to cheat, the others ignore it. The system only moves forward when the majority agrees. That’s what keeps it honest and mostly trustable. That's the whole reason Bitcoin was created (see day 2). 9/10🧵.

🔹 Who writes the next block?. It's the all reason around the Miners. They are the one creating it. They gather valid transactions, seal a block, and publish it. Think of it like stamping a page:.“These are the movements. Everyone agrees.”. 8/10🧵.

🔸What is a UTXO?. It means Unspent Transaction Output. It’s a fancy way to say:.“This piece of Bitcoin hasn’t moved yet.”.You can use one or more UTXOs when you pay .and you often get change back. 7/10🧵.

🔹 How Bitcoin stores value. Bitcoin doesn’t work like a balance. It works in chunks called UTXOs.👇. Each time you spend, you use some chunks.and send the rest back as change. Like using a €10 bill to pay €6. 6/10🧵.

🔹 Where are the coins?. They’re not in your wallet. The coin never leave the chain. Your key lets you update the record:.“This Bitcoin now belongs to this wallet.”. You don’t own the coins. You own the right to move them. 5/10🧵.
