Does lowering maxmempool to 30 (from the default 300) increase Bitcoin Core's CPU usage? from Recent Questions - Bitcoin Stack Exchange https://ift.tt/eOT7uZJ via IFTTT

I was analyzing the mempool and came across this recent block: https://mempool.space/block/00000000000000000000ab2fd9208a0567872710a717e403a24dc5113723406c It stands out for two reasons: It was mined by an unknown miner. Despite having over 30 minutes to collect transactions, it remains nearly empty. Typically, such empty blocks occur when two blocks are found in quick succession, but that doesn't seem to be the case here. Could this be due to a misconfigured solo mining client, a test, or is there another possible explanation for this behavior? from Recent Questions - Bitcoin Stack Exchange https://ift.tt/TJLWrcl via IFTTT

Increasing block emission rate or block size decreases the security of Bitcoin by increasing its fork rate. For the Nakamoto consensus to be secure the following assumption must hold true: D * block_emission_rate << 1 where << mean much smaller, and D is network delay in seconds. block_emission_rate for Bitcoin is about 0.00166 blocks/second. Thus for Bitcoin to be secure the network delay must be much lower than 600 seconds. Sompolinski et al. write about a solution for block-DAGs of locally defining a maximum latency that can be caused by an attacker: That is, even if messages currently propagate fully within 1 or 2 seconds, if an attacker may disrupt the network and cause messages to take up to 30 seconds to go through, 𝐷 should be set by the client to 30 seconds. Couldn't the parameters such as block_emission_rate and perhaps even the block size be adjusted locally and automatically as a function of the stale block rate rate ? Are fully asynchronous cons...

I recently tried to check my old Copay wallet balance but discovered that Copay no longer exists. I restored my backup in BitPay, and seeing my balance and transaction history made me feel like I was on the right track. However, I’m unable to transfer funds due to a derivation path error (m/undefined/0/0), and BitPay doesn’t seem to allow editing it. I attempted to manually recover the private key from the backup, but I ran into an issue with invalid IV/nonce values (nonce is expected to be between 7-13 characters and the one in the backup is 16). Is there any hope of recovering access to these funds? from Recent Questions - Bitcoin Stack Exchange https://ift.tt/2y01z3p via IFTTT

Given a seed or seed phrase all the different possible key pairs can be determined if BIP 32 is implemented. Understanding is a single wallet / hd seed can create an unlimited amount of keypairs. BIP44 proposes a address gap : If the software hits 20 unused addresses in a row, it expects there are no used addresses beyond this point and stops searching the address chain What is the common process for checking if the given wallet contains any bitcoin? Would all the possible addresses need to be checked? from Recent Questions - Bitcoin Stack Exchange https://ift.tt/7FOdGfB via IFTTT

I need to scan a blockchain address for future transactions of specified amount that are interested to me. For example, I need to detect future transactions in the range of from 100 USDT to 115 USDT. How to do that without scanning overall history of transaction of this specific address? Because if I scan all the history of transactions, I catch old transactions within desired range. And this is not what I need. Only future transaction should be caught once executed. Not past ones. Thank you in advance. from Recent Questions - Bitcoin Stack Exchange https://ift.tt/d93lV4B via IFTTT
