mempool policy - How much does the extra pool help with missing transactions for compact block reconstruction? - Bitcoin Stack Exchange
A concern brought up in the context of block content diverging from the default mempool policy is the reduced compact block reconstruction rates. In this context, I have seen the extra pool brought...
database - Where does Bitcoin Core keep the XOR obfuscation keys for both block data files and level DB indexes? - Bitcoin Stack Exchange
As far as I know Bitcoin Core obfuscates both block/undo data and level DB indexes with XOR. Where are those randomly generated keys actually stored? Is it self contained within the DB directories?
script - Can scriptPubKey be empty in Bitcoin transactions and how would such outputs be spent? - Bitcoin Stack Exchange
I'm trying to understand Bitcoin's consensus rules regarding empty scriptPubKey fields in transaction outputs. I've found conflicting information: Some AI sources claim that empty scriptPubKey fie...
full node - Best way to keep a sync'ed *copy* of all Bitcoin Core data on an external drive? - Bitcoin Stack Exchange
How can I always have a second copy of my Bitcoin Core data (blocks, indexes, chain state) on an external drive? The drive will only be connected to the node at times when it's not connected to sep...
mempool - If arbitrary data is inevitable, does removing OP_RETURN limits shift demand toward more harmful storage methods (like UTXO-inflating addresses)? - Bitcoin Stack Exchange
One justification for removing the OP_RETURN policy limit is that arbitrary data is “unstoppable” and will always find its way onto the blockchain. At the same time, not all data vectors have the s...
op return - If OP_RETURN needed more room, why was the 80-byte cap removed instead of being raised to 160? - Bitcoin Stack Exchange
Bitcoin originally limited OP_RETURN outputs to 80 bytes to discourage arbitrary data storage and keep the chain focused on monetary use. Recently this cap was removed, with the argument that some
synchronization - If OP_RETURN uncapping doesn’t increase the UTXO set, how does it still contribute to blockchain bloat and centralization pressure? - Bitcoin Stack Exchange
OP_RETURN outputs are provably unspendable, so they don’t add to the UTXO set. This is sometimes used to argue that uncapping OP_RETURN is “safe.” But the raw payloads are still committed to the
op return - How do v30’s changes to OP_RETURN rules and datacarriersize impact mempool cohesion and node operator autonomy? - Bitcoin Stack Exchange
Bitcoin Core v30 will for the first time allow transactions into the default mempool with more than one OP_RETURN output. The datacarriersize= setting is being repurposed so that numeric limits now...
mempool - What are the worst-case stress scenarios from uncapped OP_RETURNs in Bitcoin Core v30? - Bitcoin Stack Exchange
With Bitcoin Core v30 removing the 80-byte OP_RETURN relay cap, transactions with very large OP_RETURN payloads can now propagate by default, up to block weight limits. In a stress-test context, I’...
bitcoin core - How does uncapping OP_RETURN impact long-term fee-market quality and security budget? - Bitcoin Stack Exchange
In v30, default relay policy allows OP_RETURN outputs up to consensus limits. OP_RETURN outputs are provably unspendable (so they don’t grow the UTXO set), but they still consume block weight/size ...
bitcoin core - If OP_RETURN relay limits are ineffective, why remove the safeguard instead of keeping it as a default discouragement? - Bitcoin Stack Exchange
Bitcoin Core v30 removes the long-standing 80-byte OP_RETURN cap, raising the default to the full consensus limit (~4 MB) while deprecating -datacarriersize. Proponents argue that OP_RETURN restric...
op return - Implications of OP_RETURN changes in upcoming Bitcoin Core version 30.0 - Bitcoin Stack Exchange
As you may know, there has been a debate around the upcoming release of Bitcoin Core. I hear the arguments against it and I agree that Bitcoin is money, not a storing database, and strictly only mo...
op return - Why are OP_RETURN transactions discouraged? Does using version or locktime make any difference? - Bitcoin Stack Exchange
Why are OP_RETURN transactions discouraged? Are they paying less fees compared to other transactions? Will it make any difference if same thing is done using version or locktime when data is either...
bitcoin core - What analysis shows OP_RETURN uncapping won’t harm block propagation or orphan risk? - Bitcoin Stack Exchange
One of the reasons given for raising the OP_RETURN default in v30 is that restrictions are ineffective: miners and users can bypass relay policy anyway. But allowing megabytes of arbitrary OP_RETUR...
p2pkh - How to include arbitrary data when spending an UTXO while keeping the transaction valid? - Bitcoin Stack Exchange
I want to include some random (for me it is not really random 🙂) data when unlocking an UTXO. I would like to keep the spending secured by a classic signature. At first, I thought about using P2WP...
mining pools - Why can't default minimum fee rate be changed to 0.1-0.2 sat/vByte? - Bitcoin Stack Exchange
Main question (focus on this incase you are looking to close it as "needs focus"): Why can't we change default minimum fee rate to something below 1 sat/vByte? It was done in past: https://
My original TXid was replaced in a Replace-by-fee, and the btc was redirected to another wallet that isn't mine. Help please I don't understand - Bitcoin Stack Exchange
So I initiated a withdrawal from BetOnline (casino/poker platform) and withdrew it to my cash app wallet. I have done this hundreds of times between the two and have never had an issue before. I se...
