Topic: btc rpc how to get the output address (Read 212 times)

If you are using Linux shell and run my script (bitcoin.tx.sh), which is a bitcoin-cli wrapper:


The script uses grondilu's bitcoin-bash-tools to make the address from the pub key..
Script from my githubh repo: https://github.com/mountaineerbr/scripts/blob/master/bitcoin.tx.sh


The next script wraps grondilu's bitcoin bash functions. Here I
get the ASM (assembly) code, pack, double-sha256 and then
convert it to address with byte number 00.

If you want an address, I suppose you could construct an address from the public key.

It doesn't have a wallet address because it's a "Pay to Pubkey" script.

You're used to see "pay to pubkey hash" scripts... The hash of the pubkey IS the address

In this case, it's just the pubkey... There is no "address"... If you were the owner of this wallet, you could spend the funds by providing a valid signature which can be verified against the pubkey that was funded. That's about it

You're just looking at very old blocks, p2pk scripts are very rare nowadays.

Thank you for your reply. The example in the document you sent has "addresses": [
                     "1Q2TWHE3GMdB6BZKafqwxXtWAWgFt5Jvm3"
                 ], I want to know why the structure I see does not have a wallet address, so I don’t know which wallet to transfer to

I am learning the transfer structure of Bitcoin's blockchain. I have encountered a problem and I hope to get help. First of all, thank you. I want to analyze the UTXO transfer in and out of a block, but the following json does not tell Which address did I transfer to, and how do I know which address the expense was transferred to? Why didn't I see vout['scriptPubKey']['addresses']，In the following message'value': Decimal('49.98000000'), how can I know where the 49 BTC went?
