Calculating addresses from Bitcoin transaction data
What would be the easiest way to retrieve addresses that are used in specific transaction? For instance, if you look at following transaction which is retrieved by getblock
of JSON RPC with argument of verbosity 2 (https://developer.bitcoin.org/reference/rpc/getblock.html),
....
"tx":[
{
.....
"vin":[
{
"coinbase":....,
"sequence": ...
}
],
"vout":[
{
"value":...,
"n":...,
"scriptPubKey":{
"asm":...,
"desc":...,
"hex":...,
"type":...
}
}
]
How can I know receiver's address by looking at "scriptPubKey"? One of the challenges was there were different types of scriptPubKey so that it was kind of hard to parse them. Does anyone know best way to retrieve public address from any kind of scriptPubKey, so that the result will be matched with the addresses that are used by block explorers?
P.S. I think some of the newer transactions actually contain "Address" field inside the scriptPubKey, but older transactions do not. I want to have a generalized method that can handle any kind of transactions.
