RT hodlonaut (@hodlonaut)1/In 2025 Bitcoin Core removed a decade-old mempool policy default — a configurable limit on how much non-financial data nodes would relay. OP_RETURN was effectively uncapped.Not a consensus rule. A default setting. But defaults govern what most of the network does. Which governs what miners see. Which governs what gets mined.The justification: it wasn’t working anyway, data was getting in through a loophole.What wasn’t disclosed: that loophole had been deliberately kept open.Here’s ...

Now, account abstraction.We have been talking about account abstraction ever since early 2016, see the original EIP-86: https://t.co/E4xJymAxiHNow, we finally have EIP-8141 ( https://t.co/YD9nIpsxcC ), an omnibus that wraps up and solves every remaining problem that AA was intended to address (plus more). Let's talk again about what it does.The concept, "Frame Transactions", is about as simple as you can get while still being highly general purpose. A transaction is N calls, which can read each other's call ...

RT The Bitcoin Magazine (@thebtcmag)Cluster mempool is more than a code refactor; it’s a fundamental rethink of how Bitcoin handles transactions.Here's a quick breakdown of how it works (1/5) 🧵 https://t.co/tBNwiRgs65 ...

RT Nick Szabo (@NickSzabo4)Whether you try to discourage something, or do nothing, or try to encourage it -- or seem to do these things -- each of these actions or non-actions sends a signal, often a much more powerful signal than the actual security of your effort warrants.Think about locks on your door. Would they stop a skilled and determined robber? No. Do they stop most unwanted visitors? Yes. Most predators just want dinner, and they will choose the least risky prey they can find.Since this debate mos ...

Security Considerations - Discouraging, ignoring, or encouraging actions related to security all send signals, regardless of their actual effectiveness [1] - Physical security measures, like door locks, deter most opportunistic threats, even if they don't stop determined attackers [1] - The focus is often on "locked-door" security or traffic signs, rather than absolute security, especially in areas like mempool and relay policy [2] - The inability to stop all attackers shouldn't prevent efforts to mitigate common behaviors that could harm node operators or the network [2] Network Policy - Discussions around mempool and relay policy are more about guiding behavior than ensuring strong security [2] - Alternative methods, even if weak, can send a signal and deter unwanted behavior [2]

Blockchain Transaction Management - The industry is facing challenges related to transaction clarity in mempool-based sequencing since migrating to version 0.14 [1] - Transactions may silently drop out of the mempool during congestion without sender notification, creating uncertainty [1] - The industry seeks decentralized solutions for transaction status visibility in the mempool [2] Decentralization Considerations - Externalizing transaction status from a single node is not a future-proof solution due to decentralization [2] - Different nodes may implement their own dropping policies, leading to inconsistencies in transaction expiry [2]

Bitcoin Network - Bitcoin transactions do not confirm instantly and queue in the mempool [1] - The guide explains how the BTC mempool works [1] Fee Optimization - The guide helps users leverage the mempool to avoid overpaying on fees [1]

RT Asher Hopp (@AsherHopp)Its been 18 hours since someone pushed this valid transaction with a full jpeg in op_return. For most of those 18 hours, the fee rate was sufficient for it to be considered "next block."But it hasn't been mined yet. The reason it hasn't been mined is because of filters, which bCore v30 will disable.Bitcoin Core maintainers feel that it is essential to quickly mine this jpeg, and that somehow filtering it is "bad" for mempool topology and will degrade Bitcoin services. Have you noti ...
