how to use money button support metanet
I want to write meta information through monenybutton and implement permission control
I noticed that even with
getrawtransaction RPC call still returns transactions. I assume that without the full index it will still return transactions that node software needs for other reasons (wallet transactions, UTXOs, …). But what are those cases? Which types of transactions are available even without the full transaction index? And what happens if I request a transaction that is not available?
I heard a lot of discussions mentioning IP2IP at the recent CoinGeek conference in Seoul. I really like the idea of users exchanging transactions peer-to-peer, but I am wondering how IP2IP works on a technical level?
Does it require a daemon/service running on the recipient’s computer that listens for incoming transactions or is there some other approach?
What are the possible Bitcoin scripts to create a multi-sig transaction? Please provide the script code with explanations.
I would like to see at least two types of such scripts explained (OP_CHECKMULTISIG and the one with conditional OP_IF statements that Steve Shadders showed at this CoinGeek Seoul presentation). If there are more options, please list them as well.
Is it possible to get a current unspent transaction outputs set from a Bitcoin node? Or more generally, is it possible to get a UTXO set at an arbitrary block height?
If not possible through a node, is there any other solution that provides that?
