Class CTx

Represents a confidential transaction. Also known as CMutableTransaction on the C++ side. Examples:

const { CTx, CTxId, TxIn, TxOut, ChildKey, Scalar, SubAddr, SubAddrId, DoublePublicKey, OutPoint, PublicKey, TokenId, CTX_ID_SIZE } = require('navio-blsct')
const { randomBytes } = require('crypto')
const cTxIdHex = randomBytes(CTX_ID_SIZE).toString('hex')
const cTxId = CTxId.deserialize(cTxIdHex)
const numTxIn = 1
const numTxOut = 1
const defaultFee = 200000
const fee = (numTxIn + numTxOut) * defaultFee
const outAmount = 10000
const inAmount = fee + outAmount
const outPoint = OutPoint.generate(cTxId)
const gamma = 100
const spendingKey = Scalar.random()
const tokenId = TokenId.default()
const txIn = TxIn.generate(inAmount, gamma, spendingKey, tokenId, outPoint)
const viewKey = new ChildKey().toTxKey().toViewKey()
const spendingPubKey = new PublicKey()
const subAddrId = SubAddrId.generate(123, 456)
const subAddr = SubAddr.generate(viewKey, spendingPubKey, subAddrId)
const txOut = TxOut.generate(subAddr, outAmount, 'navio')
const cTx = CTx.generate([txIn], [txOut])
for (const cTxIn of cTx.getCTxIns()) {
  console.log(`prevOutHash: ${cTxIn.getPrevOutHash()}`)
  console.log(`prevOutN: ${cTxIn.getPrevOutN()}`)
  console.log(`scriptSig: ${cTxIn.getScriptSig()}`)
  console.log(`sequence: ${cTxIn.getSequence()}`)
  console.log(`scriptWitness: ${cTxIn.getScriptWitness()}`)
}
for (const cTxOut of cTx.getCTxOuts()) {
  console.log(`value: ${cTxOut.getValue()}`)
  console.log(`script_pub_key: ${cTxOut.getScriptPubKey()}`)
  console.log(`blsctData.spendingKey: ${cTxOut.blsctData().getSpendingKey()}`)

  console.log(`blsctData.blindingKey: ${cTxOut.blsctData().getBlindingKey()}`)
  console.log(`blsctData.viewTag: ${cTxOut.blsctData().getViewTag()}`)

  console.log(`blsctData.rangeProof.alpha_hat: ${rp.get_alpha_hat()}`)
  console.log(`blsctData.rangeProof.tau_x: ${rp.get_tau_x()}`)
  console.log(`tokenId: token=${cTxOut.getTokenId().getToken()}, subid=${cTxOut.getTokenId().getSubid()}`)
  console.log(`vector_predicate: ${cTxOut.getVectorPredicate()}`)
