That would mean users would be able to adapt\nfees and get different quality of service depending on current capacity.\nFor example if peak load is 10x average load, then at those times fees\nwould be higher and users would delay transactions to smooth out demand.\n\nOn Sat, Jun 27, 2015 at 7:20 PM, Peter Todd \u003cpete at petertodd.org\u003e wrote:\n\n\u003e On Sat, Jun 27, 2015 at 12:19:04PM -0400, Michael Naber wrote:\n\u003e \u003e That test seems like a reasonable suggestion; 840GB is not prohibitive\n\u003e \u003e given today's computing costs.

Remember I'm talking about mining here, not\n\u003e just hashing - the process of selling your hashpower to someone else who\n\u003e is actually doing the mining.\n\u003e\n\u003e As for \"approximately as profitable\", based on a 10% profit margin, a 5%\n\u003e profitability difference between a negligable ~0% hashing power miner\n\u003e and a 50% hashing power miner is a good standard here.\n\u003e\n\u003e The hard part here is basically keeping orphan rates low, as the %5\n\u003e profitability different on %10 profit margin implies an orphan rate of\n\u003e about 0.5% - roughly what we have right now if not actually a bit lower.\n\u003e That also implies blocks propagate across the network in just a few\n\u003e seconds in the worst case, where blocks are being generated with\n\u003e transactions in them that are not already in mempools - circumventing\n\u003e propagation optimization techniques. As we're talking about small\n\u003e miners, we can't assume the miners are directly conneted to each other.\n\u003e (which itself is dangerous from an attack point of view - if they're\n\u003e directly connected they can be DoS attacked)\n\u003e\n\u003e 2) Medium to long term plan to pay for hashing power. Without scarcity\n\u003e of blockchain space there is no reason to think that transaction fees\n\u003e won't fall to the marginal cost of including a transaction, which\n\u003e doesn't leave anything to pay for proof-of-work security. A proposal\n\u003e meeting this criteria will have to be clever if you don't keep the\n\u003e blocksize sufficiently limited that transaction fees are non-negligable.\n\u003e One possible approach - if probably politically non-viable - would be to\n\u003e change the inflation schedule so that the currency is inflated\n\u003e indefinitely.\n\u003e\n\u003e --\n\u003e 'peter'[:-1]@petertodd.org\n\u003e 0000000000000000007fc13ce02072d9cb2a6d51fae41fefcde7b3b283803d24\n\u003e\n\u003e _______________________________________________\n\u003e bitcoin-dev mailing list\n\u003e bitcoin-dev at lists.linuxfoundation.org\n\u003e https://lists.linuxfoundation.org/mailman/listinfo/bitcoin-dev\n\u003e\n\u003e\n-------------- next part --------------\nAn HTML attachment was scrubbed...\nURL: \u003chttp://lists.linuxfoundation.org/pipermail/bitcoin-dev/attachments/20150627/df971066/attachment.html\u003e"}
