According to @BitMEXResearch, the recent Bitcoin Core update raised the OP_RETURN relay policy filter limit but did not change the actual OP_RETURN size limit or the Bitcoin blocksize limit, so this is not a blocksize increase (source: @BitMEXResearch). According to @BitMEXResearch, maintaining a strict blocksize cap is presented as the robust long-term defense against spam-like data (e.g., music collections or encrypted documents), whereas relay filters are neither effective nor decentralization-friendly because a small minority of nodes can bypass them and effective filtering creates centralization pressure (source: @BitMEXResearch). According to @BitMEXResearch, the small-block position remains intact with a reasonable blocksize limit designed to protect the network from spam, confirming no structural capacity expansion for BTC introduced by this change, a status important for traders tracking on-chain conditions and decentralization risks (source: @BitMEXResearch).

According to @BitMEXResearch, relying on miners to behave as good actors works only if mining is centralized, whereas in a decentralized and competitive industry miners rationally maximize next-block revenue. source: BitMEX Research. They state that during the Blocksize War, the view that miners would voluntarily keep blocks small was unrealistic, and that without a hard blocksize limit miners would produce massive blocks filled with any fee-paying transactions, so a limit is needed to prevent oversized blocks. source: BitMEX Research. For traders, the takeaway is that Bitcoin blockspace policy depends on protocol rules rather than voluntary miner restraint, so expectations should not assume miners will forgo revenue to be good actors. source: BitMEX Research.

According to BitMEX Research on Twitter, the presence of 'junk' data in a blockchain increases blockchain bloat and raises node operation costs, but they clarify that all types of data contribute equally to these issues, not just 'junk' data. This is why the blocksize limit exists—to control blockchain size and keep node costs manageable for traders and operators (source: BitMEX Research Twitter, May 1, 2025). Understanding the blocksize limit is critical for crypto traders evaluating transaction costs and network efficiency.

According to BitMEX Research, recent updates in the Bitcoin protocol have addressed several significant issues. These include fixing transaction malleability, resolving the scaling issue related to sighash operations, and enabling a faster blocksize limit increase without the need for a comprehensive hardfork. These improvements are crucial for enhancing Bitcoin's transaction efficiency and scalability, which could impact trading dynamics positively.
