Did you know?! Fun Hack Fact Friday

Did you know?!

Bitcoin Addresses are composed of a version byte which identifies the network where to use the address and the hash of a public key. So we can go backwards and generate a bitcoin address from the ScriptPubKey and the network identifier.

var paymentScript = publicKeyHash.ScriptPubKey;
var sameMainNetAddress = paymentScript.GetDestinationAddress(Network.Main);
Console.WriteLine(mainNetAddress == sameMainNetAddress); // True

It is also possible to retrieve the hash from the ScriptPubKey and generate a Bitcoin Address from it:

var samePublicKeyHash = (KeyId) paymentScript.GetDestination();
Console.WriteLine(publicKeyHash == samePublicKeyHash); // True
var sameMainNetAddress2 = new BitcoinPubKeyAddress(samePublicKeyHash, Network.Main);
Console.WriteLine(mainNetAddress == sameMainNetAddress2); // True

Note: A ScriptPubKey does…
