Where the transaction happens?

I try to find everywhere in blockstack-core but can’t find where the transaction happens, could anyone tell me in which python file? Thanks!

IIRC blockstack core doesn’t do any of the transactions - they are instead made on the client side and broadcasted via other Apis like bitcore, a generic bitcoin TX server.

Thanks, so it is in the blockstack.js or anywhere else?

Yes, more or less. You can see how it works here, though it’s a little complicated:

github.com

blockstack/blockstack-browser/blob/5f7fa28672abfd53ee454ff96283072a499ab869/app/js/profiles/store/registration/actions.js#L93


.then((response) => {
  if (!response.ok) {
    logger.error(`Subdomain registrar responded with status code ${response.status}`)
    return Promise.reject(new Error('Failed to register username'))
  }
  return response.text()
})
.then((responseText) => JSON.parse(responseText))
}


function registerDomain(myNet, tx, domainName, identityIndex, ownerAddress, paymentKey, zoneFile) {
if (!paymentKey) {
  logger.error('registerName: payment key not provided for non-subdomain registration')
  return Promise.reject('Missing payment key')
}


const compressedKey = `${paymentKey}01`
const coercedAddress = myNet.coerceAddress(ownerAddress)


let preorderTx = ''
let registerTx = ''

tl;dr:

make the name pre order transaction
make the actual order transaction
make the zone file
call blockstack.js to send them out

In blockstack.js the main net is defined to use https://broadcast.blockstack.org. What application is running there?

I’m confused as well. But maybe we can discuss it:joy:
