If transaction hashes only are stored in blocks, then where is OP_RETURN data stored?
An answer to a previous question and the whitepaper both agree that blocks don’t store full transactions, but rather, transaction hashes.
So then, what if I add data in OP_RETURN, say, the text “Hello, world!” Isn’t that a transaction output, or at least contained in an output, and therefore part of a transaction?
If not, or if so and only transaction hashes, not transactions themselves persist, then how does the OP_RETURN data stay on the blockchain?
How to get the current UTXO set?
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?
Double hash in Bitcoin
what exactly is this? Does this mean every TX gets hashed twice? How does it help to filter the content from the block chain (As Dr. Wright said)? Why cant i hash it just once and save the hash of the TX and prune the data (illegal)? Isnt the content now filtered with just a single hash? or am i getting it wrong?
Read twetch data through Bitquery
I want to select all data and analyse twetch data through Bitquery/Bitbus. Could anyone help me to understand protocol of this app?
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?
Provide examples of multi-sig scripts
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.
How does IP2IP work?
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 is the most interesting/exciting script that was made possible by the Genesis upgrade?
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?
what is the cheapest computer to run SV
What is the cheapest desktop I can buy to run SV node at home and have it handle the biggest blocks today?
A link would be appreciated
