Check Document

Instructions

Write a node script that exports the function checkDocument() that :

  • takes as parameter a transaction id and a string
  • connects to a local node (http://localhost:8545)
  • returns the date, as a unix timestamp, that the document was added to the blockchain if the transaction id and the string match and returns 0 otherwise
function checkDocument(text, txID) {
  //...
}
module.exports = checkDocument;

Usage

checkDocument(
  "Hello world!",
  "0x49c8803ea126179502d59707dbcd9e9de15f5d441920936e9ec6fd78dd6468d8"
);
