What is segwit?
Before diving into the details, let’s quickly cover what segwit is. Segwit is a new standard it uses a novel consensus algorithm called Lightning Network (LN) to face-to-place transactions.
Nbitcoin: A Lightweight Bitcoin Implementation
Nbitcoin is an open-source, decentralized implementation of Bitcoin designed for small-scale users and developers who want to use bitcoin without the hassle of installing a full node or mainitaining a complex network. It supports multiple programs and has a relatively low barrier to entry.
Signing SegWit Transactions with Nbitcoin
To sign a transaction using segwit with nbitcoin, follow these steps:
npm install nbitcoin
(if you are using node.js) orpip install nbitcoin
.`JavaScript
Const NBT = Require (‘Nbitcoin’);
// Create a New Wallet
let mywallet = nbt.newwallet ();
// Create a new transaction from Another Wallet
mywallet.from (‘1234567890abcdef’)
.Adaddress (‘1A1B2C3D4E5F6G7H8i9J10K11L12M13N14O15P16Q17R18S19T20U21V223X24Y25Z26’)))
.setfee (0.00001)
.Addinput ({{{
‘from’: {
‘Address’: ‘1234567890abcdef’,
‘Amount’: 10,
‘scriptsig’: {
‘PubKey’: ‘1A1B2C3D4E5f6G7H8i9J10K11L12M13N14O15P16Q17R18S19T20U21V223X24Y25Z26’,
‘sequence’: 0
}
},
‘to’: {
‘Address’: ‘1A2B3C4D5E6F7G8H9i10J11K12L13M14N15O16P17Q18R19S20T21U22V23W24X25Y26Z27’
}
})
.Sign (‘0x1234567890abcdef’);
`
() Nbt.newwallet ()
And then add another wallet from which to transfer funds. We set the fee to 1% of the transaction amount (in this case,
sign
method to sign the transaction:`JavaScript
mywallet.sign (‘0x1234567890abcdef’);
`
