LegendaryActivity: 1526Merit: 1007 Soft block size limit reached, action required by YOU March 06, 2013, 09:44:20 AM

Last edit: March 06, 2013, 11:15:40 PM by Mike Hearn #1 without a hard fork. We have now reached this limit. Transactions are stacking up in the memory pool and not getting cleared fast enough.



What this means is, you need to take a decision and do one of these things:



Start your node with the -blockmaxsize flag set to something higher than 250kb, for example -blockmaxsize=1023000. This will mean you create larger blocks that confirm more transactions. You can also adjust the size of the area in your blocks that is reserved for free transactions with the -blockprioritysize flag.

Change your nodes code to de-prioritize or ignore transactions you don't care about, for example, Luke-Jr excludes SatoshiDice transactions which makes way for other users.

Do nothing.

If everyone does nothing, then people will start having to attach higher and higher fees to get into blocks until Bitcoin fees end up being uncompetitive with competing services like PayPal.



If you mine on a pool, ask your pool operator what their policy will be on this, and if you don't like it, switch to a different pool. By default Bitcoin will not created blocks larger than 250kb even though it could do so. We have now reached this limit.

Hopefully the most pools will not increase their Blocksize limit so we get a good simulation of how the Bitcoin environment behaves when we bump against a limit. All previous versions of currency will no longer be supported as of this update

OK, wrong word. Still I hope that most pools will not immediately lift / increase their limit. So we know what will happen when we reach the hard limit, which can't be changed so easily.



So let us bump against this for a few month. And lift it only if it really damages Bitcoin. OK, wrong word. Still I hope that most pools will not immediately lift / increase their limit.

Miners (all miners) need to understand what they're doing. The time when people could just click "Generate coins" and be done with it are long gone. It's very important that miners monitor the health of the network and understand what their software is doing.



For pools, the operators need to state what their block construction policies are, and the people with the hardware need to understand those policies and find pools with good ones.



That's far more than I or anyone else can do alone. Miners need to hold their pools accountable.

LegendaryActivity: 1750Merit: 1002 Re: Soft block size limit reached, action required by YOU March 07, 2013, 12:46:09 AM #13 BTC Guild started setting up a new server this morning running modified block rules. Currently trying out a 500,000 byte maxblocksize. The problem is with larger blocks, you increase the chance of orphans since it will take at least twice as long to propagate, if not more. I've modified the fee settings to prefer fee based transactions when increasing the block size past 50 KB, so hopefully the increase in fees per block offset the orphan rate increase.
