Miners can already soft-fork to reduce the maximum block size. If 51% of miners agree to a 250kB block size, then that is the maximum block size. The question being discussed is what is the maximum block size merchants and users will accept. This puts a reasonable limit on the maximum size miners can increase the block size to. In effect, the block size is set by the minimum of the miner's and the merchants/user's size.min(miner, merchants/users). > This allows the well-funded Bitcoin ecosystem to continue building > systems which rely on transactions moving quickly into blocks while > pretending these systems scale.

If miners could specify the maximum block size in their block headers, then they could coordinate to adjust the block size. If 75% vote to lower the size, then it is lowered and vice versa for raiding. Every 2016 blocks, the votes are counter. If the 504th lowest of the 2016 blocks is higher than the previous size, then the size is set to that size. Similarly, if the 504th highest is lower than the previous size, it becomes the new size. There could be 2 default trajectories. The reference client might always vote to double the size every 4 years. To handle large blocks (>32MB) requires a change to the p2p protocol message size limits, or a way to split blocks over multiple messages. It would be nice to add new features to any hard-fork. I favour adding an auxiliary header. The Merkle root in the header could be replaced with hash(merkle_root | hash(aux_header)). This is a fairly simple change, but helps with things like commitments. One of the fields in the auxiliary header could be an extra nonce field. This would mean fast regeneration of the merkle root for ASIC miners. This is a pretty simple change. -------------- next part -------------- An HTML attachment was scrubbed...
