According to @BitMEXResearch, Bitcoin relay filters aimed at BRC-20 traffic are unlikely to work because if roughly 10% of nodes ignore them, the looser relay policy wins across the network, which is how Bitcoin works, source: BitMEX Research on X, Oct 8, 2025. @BitMEXResearch adds that even with 99% adoption, spammers can adapt, making anti-spam efforts a whack-a-mole battle that asymmetrically favors spammers, source: BitMEX Research on X, Oct 8, 2025. @BitMEXResearch warns of four concrete side effects from fighting spam with stricter relay rules: encouraging direct peering with miners that increases centralization pressure, breaking Compact Blocks, breaking pre-block validation caching, and breaking fee estimation, source: BitMEX Research on X, Oct 8, 2025. For trading workflows, the listed breaking fee estimation directly degrades reliability of fee-based execution planning and confirmation-time models for BTC transactions, source: BitMEX Research on X, Oct 8, 2025.

According to @BitMEXResearch, raising Bitcoin’s OP_RETURN policy limit benefits individual users by making Compact Blocks and pre-block signature validation caching more effective for nodes that run a higher limit (source: BitMEX Research on X, Sep 30, 2025). According to @BitMEXResearch, the pro-filter camp wants users to incur personal costs and operate less effective nodes for the common good of deterring spam, contrasting with a policy consistent with individual sovereignty (source: BitMEX Research on X, Sep 30, 2025). According to @BitMEXResearch, miners selecting transactions to maximize revenue reflects a pro-business, pro-market approach, whereas pro-filter advocates ask miners to sacrifice revenue for the greater good, framing the policy discussion around fee revenue selection rather than a political shift (source: BitMEX Research on X, Sep 30, 2025; BitMEX Research blog: blog.bitmex.com/all-for-one-one-for-all/).

According to @Excellion, Bitcoin Core is trying to prevent private mempools, has removed OP_RETURN limits, and this is driving thousands of users toward Bitcoin Knots while compact block relay breaks, accelerating a shift to private mempools, source: X/@Excellion on Sep 22, 2025. For traders, increased use of private mempools reduces mempool overlap and can impair BIP152 compact block efficiency, potentially increasing relay bandwidth needs and confirmation latency during volatility, source: BIP152 Compact Block Relay (Bitcoin Core specification). BTC traders should monitor on-chain feerate distributions, compact block reconstruction success on nodes, and client share between Bitcoin Core and Bitcoin Knots as early indicators of fee pressure and settlement delays, source: Bitcoin Core and Bitcoin Knots documentation and network policy references; X/@Excellion.
