> Increasing Blocksize increases centralization, again, diminishing its role as a more perfect form of money. (Read, “Blocksize Wars”) Yes, one should read "The Blocksize War". The OP_RETURN size limit has been 1MB for well over a decade. A recent version of Bitcoin Core has increased the OP_RETURN relay policy filter limit, not the actual size limit. This recent change is not a blocksize limit increase. In Chapter 2 of "The Blocksize War" it explains one of the key reasons why we need a blocksize limit, because otherwise the chain will be full of loads of spam or as the book puts it "music collection or encrypted documents". The small blockers won the war. We have a reasonable blocksize limit in place. This protects us from the spam. Filters are not effective at stopping transactions people want to make. Only a tiny minority of nodes need to ignore the filters and then the filters wont work at all. We should not fight an unwinnable war. And to the extent the filters do work at reducing the propagation of transactions people want to make, that causes centralization pressure, pretty much the same kind of centralization pressure the small blockers fought to stop in the blocksize war. Filters are not a robust long term solution to fighting against mining incentives or fighting against spam. Bitcon should not rely on ineffective measures like filters. The blocksize limit is that robust long term solution. Chapter 2 Extract > Small blockers also believed full blocks were inevitable anyway. After all, if blockspace was available, why not use it up? Anyone could store anything they liked in the blockchain, for instance their music collection or encrypted documents. Demand for cheap, highly-replicated storage was essentially unbounded, they argued. Asking for the limit to increase above expected demand was therefore nonsense. Indeed, one person could easily fill all the space up themselves. The retort to this point from the larger blockers circled back to the mining incentive argument; miners would not do this, they claimed, miners would not let this amount of data in the blocks.(BitMEX Research)
