How is merkle tree and merkle root calculated?
How to calculate a merkle tree? What is “merkle proof” and how does it fit into the SPV? How does one validate a merkle proof? And how all that affects Bitcoin?
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.
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?
Non-standard scripts can finally be used without limits on the Bitcoin SV blockchain thanks to the Genesis upgrade. We think that this will accelerate the innovation and we will soon see a variety of new scripts being used on a regular basis.
What is the one that is the most exciting, interesting and/or powerful in your opinion? Which new use cases will it enable?
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?
