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, individual non-economic relaying nodes can significantly influence Bitcoin when they loosen relay policies, whereas attempts by such nodes to tighten relay policies tend to matter less for network behavior (source: @BitMEXResearch). Bitcoin Core defines standardness and relay policy rules that govern which transactions are propagated, so looser relay increases the set of transactions reaching mempools and miners, directly linking relay policy to transaction propagation and inclusion chances (source: Bitcoin Core policy documentation). For traders, changes that broaden relay can alter mempool composition and feerate competition, impacting short-term BTC confirmation probabilities and fee volatility to monitor during intraday execution (source: Bitcoin Core mining and mempool documentation). Practical signals include tracking mempool size and median feerates on public explorers to detect propagation shifts that affect execution costs and timing (source: mempool.space dashboard).

According to BitMEX Research, when Bitcoin nodes materially disagree on transaction relay rules, the less stringent and incentive-compatible relay policy tends to prevail across the network.
