According to @ItsDave_ADA, he announced on Nov 14, 2025 a fluent Cardano transaction builder in .NET that supports full wallet restoration, UTxO management, type-safe transaction construction, automatic balance validation, typed multi-output transactions, fee estimation, and clean CBOR generation for submission. source: @ItsDave_ADA on X

According to @BitMEXResearch, removing the OP_RETURN filter is strictly the better choice for your node. Source: @BitMEXResearch. If large OP_RETURNs are used, removal is necessary so Compact Blocks, pre-validation caching, and fee estimation work effectively on the node. Source: @BitMEXResearch. If large OP_RETURN usage remains low, nodes gain only a tiny benefit due to low usage rates, but removal is still preferable. Source: @BitMEXResearch. For BTC market participants, the source highlights fee estimation effectiveness and Compact Blocks performance, both relevant to on-chain fee strategies and confirmation risk management.

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.
