Goal to capture all the bitcoin-cli help text in a single file, then later annotate with more ("account") addwitnessaddress "address" backupwallet "destination".

Multisig on the command line By Matthew Bitcoin cli wallet address Introduction The goal of this guide is to demonstrate a multi-signature collaboration between bcoin users who may or may not trust each other.

We will use only terminal commands to illustrate the process. For a deeper dive into how multisig transactions are constructed in JavaScript with the library, see Bitcoin cli wallet address Multi-signature Transactions.

All the commands in this guide and so many bitcoin cli wallet address There are important details in those docs regarding API keys, wallet tokens, and other security measures that are essential for using bcoin on mainnet.

For this guide, we will just play in regtest mode and skip over those steps. Each of them will create a multisig wallet on their own computers, and they'll share their wallet's default account's extended public key with each other. Once everyone knows everyone else's extended public key, they will click here be able to derive multisig receive addresses.

Creating wallets Start by launching bcoin in regtest mode.

What Is A Full Node?

We'll use environment variables so we don't have to type the network parameter each time. There are bitcoin cli wallet address options available for wallet creation, but all Alice needs to do is set up her wallet as a 3-of We'll also specify Segregated Witness.

When bcoin created this wallet, it generated entropy and created a Https:// master private key for Alice. That will be the key she uses to sign the multisig transaction bitcoin cli wallet address she approves.

This will be a bit tedious for us because we have to do it for everybody but remember in practice, each participant only needs to do this once.

getnewaddress (0.17.0 RPC)

Now Alice's wallet is fully initialized. She can generate an endless series of receive and change addresses and watch the blockchain for transactions! Normally in bitcoin cli wallet address a "watch-only" wallet only has public keys.

It can "watch" a bitcoin address private key finder of addresses, but not spend. In this case, Alice can not spend from this wallet by herself, despite the wallet not being "watch-only".

She only has one private key and four public keys per address.

Bob, Charlie, David, and Erica all go through the same process of importing the other keys. In the end, bitcoin cli wallet address five participants will have the same wallet structure, and identical addresses.

Assuming each person is running their own bcoin full node on their own secure machine, they bitcoin cli wallet address now have a totally decentralized multi-signature wallet!

Bitcoin cli wallet address

The participants do not need to trust bitcoin cli wallet address other to set up or use this scheme. Some participants may even be using a hardware wallet like a Ledger connected to their bcoin full node with the bledger package.

Let's spend some money as a team! So now we have five wallets.

Bitcoin cli wallet address

Each wallet has its own account xprv that can generate many private and public key pairs. The private keys are used to add the participant's signature to transactions.

Running A Full Node

Each wallet also has an account xpub from each of the four other participants. These can be used to derive the other 4 public keys used in each multisig address. This structure allows each participant to generate the same receiving address while only being able to add their own unique signature to transactions.

All five bitcoin cli wallet address show the same receiveAddress. Let's fund it! This is where it gets bitcoin cli wallet address ANY single participant can create a transaction spending from the multisig address.

This transaction will be created and signed by that first participant. This is often called a "proposal" in multisig wallet schemes. Bitcoin cli wallet address transaction with its single signature is NOT valid and will be rejected from the Bitcoin network.

Because our scheme is 3-of-5, we only need to get two other participants to add their signatures before the transaction is valid.

Although bcoin does not currently comply with the proposed standard BIP Partially Signed Bitcoin cli wallet address Transactions the participants can pass around these blobs in the same way.

Erica is the most responsible friend in the group.

Bitcoin cli wallet address

When bcoin creates a multisig transaction, it places null bytes 0x00 where each signature will eventually go. The signatures must be placed in the same order as the public keys in the redeem script, which is why Erica's signature is not the first on the stack.

This lexicographical bitcoin cli wallet address of public keys in multi-signature redeem scripts is an accepted standard in the Bitcoin development community.

Bitcoin cli wallet address

Let's say Erica tried to make a unilateral decision here bitcoin cli wallet address broadcast this transaction with only her signature -- what would happen? Ok then!

Bitcoin cli wallet address

Let's get a few more signatures. Maybe Alice and Bob are busy engaging in some other cryptography demonstration they always are how about Charlie and David?

It generates wrong bitcoin address

Take a look at the witness, it looks a lot different bitcoin cli wallet address Bitcoin cli wallet address first transaction. The number of stack items has gone from 7 to 5.

Because bcoin has detected that the multisig policy bitcoin cli wallet address been completed, and removed the 2 extra placeholders. Why is there still an empty stack item on top? Well for that, you'd need to bitcoin cli wallet address Satoshi Nakamoto.

Previous commands

We're done. David added bitcoin cli wallet address final signature and now holds a valid Bitcoin transaction. Let's send it to the bitcoin cli wallet address

  2. In my opinion you are not right. I am assured. I suggest it to discuss. Write to me in PM, we will communicate.
