Transaction Serialization

https://bitcoincore.org/en/segwit_wallet_dev/#transaction-serialization

The original transaction format:

nVersion | txins | txouts | nLockTime

The new serialization format BIP-144

const crypto = require('crypto');
const bitcoinjs = require('bitcoinjs-lib');

module.exports = (user_id, currency_type) => {

  // Generate a P2SH, pay-to-multisig (3-of-4) address

  // แปลง user_id ให้เป็น string ก่อน
  let shash = String(user_id);

A nonce is just a sequential number tied to every transaction that represents the number of transactions the sender account has made on the network. You can think of it the same way as the auto-incrementing id field in a SQL database. It's a mechanism to ensure that the same transaction isn't submitted twice.

Example: You create a brand new Ethereum account. Your friend Alex sends you 5 ETH. This doesn't effect your account's nonce because you weren't the sender account. You then send 1 ETH to your friend John. The transaction that sends that 1 ETH needs to have the nonce of 0, because it's the first transaction your account is sending. Later that day, you send 2 ETH to your friend Bradley. That transaction will need to have a nonce of 1.

If you're going to set the nonce programmatically in a Dapp you can do it with web3 like this web3.eth.getTransactionCount(acct) because the number of transactions that an account has sent, will be the next nonce that it needs to use.

All of the opcodes and their complete descriptions are available in the Ethereum Yellow paper. For convenience, though, I've made a handy reference list of them all:

0s: Stop and Arithmetic Operations

0x00    STOP        Halts execution
0x01    ADD         Addition operation
