Pay x to 2-of-3 of Alice, Bob, Judy (MULTISIG) SIGNED(ALICE) Alice Bob To: Alice From: Bob Pay x to Bob SIGNED(ALICE, BOB) (normal case) Pay x to Alice SIGNED(ALICE, JUDY) (disputed case) Judy. 43684.

The puzzle becomes an output of her Bitcoin transaction. · The bitcoin blockchain doesn’t care who owns the bitcoin or how it was acquired, but it does give us a mechanism to verify ownership without a trusted third party. ELSE. This 1 Bitcoin is then locked up in a multisig address that both parties can sign off on if they want to close the channel. · Imagine that Alice, who controls an address containing one unspent output worth 10 bitcoin (BTC), wants to pay Bob 10 bitcoin.

She wants to send Bitcoin to one of her contacts, Bob. Essentially, Alice’s wallet breaks her funds into two payments: one to Bob, and one back to herself. 5 BTC +.

Here’s how it works: Say Alice wants to transfer one bitcoin to Bob. 99 BTC, so this is added as an output. 00:06:00 So there's still a possibility for Alice to actually send this transaction to the blockchain and reclaim the top Bitcoins.

Bob wants to send 1 bitcoin to Alice so he uses his private key to sign the message I, Bob sends 1 bitcoin to Alice. Alice’s pubkey script then pushes the pubkey hash that Bob gave her for the first transaction. Alice wants so send bob two bitcoins

Double-Spend Attack: – Alice purchases service from Bob and pays in coins. Now Bob “owns” them. · Alice and Bob exchange a set of addresses, keys, zero-knowledge proofs and signatures. · And when Alice wants to send those Bitcoins to Bob, she just unlocks her lock and puts the Bitcoins in a vault with Bob’s lock on it. Alice sends a payment of 0. So it's going to send the ciphertext and y to Alice instead, so if Alice learns X she can decrypt Q and get epsilon star. · then Alice wants to send some money to Bob. – Eventually, honest node will be picked, who will include Bob’s transaction in proposed block. If Bob wants to send Alice some bitcoins in exchange for a product, then one of them has to make the first move, and trust that the other will follow through. . . · For example, if Alice has a bitcoin address with one bitcoin in it, and she only wants to send Bob half a bitcoin, then she would have to send Bob that entire bitcoin.
