The problem with bitcoin is the idea that it even requires a mining pool or transaction fee. Bitcoin will die the moment someone figures out how to build a decentralized crypto-currency that doesn't need a stupid idea like "mining" to be functional and secure.

I'm not holding my breath

Transactions will get processed eventually without a mining fee. It will just take longer, because many miners prioritize transactions with fees. "Mining" will eventually be unprofitable as well. And the only advantage to mining pools is to reduce variability in block payouts.

You can't get rid of mining - that's the cost of trust-less decentralization.

You might be able to make mining more efficient, or based around some other finite resource besides computation power (like storage), but even that's a long-shot.

Destroy energy to bury the historic record under irreversible computation. Think about it in terms of physics, and what makes the best kind of money.

Earlier quoted context omitted.

If the pending transactions fit in a block, there's not much incentive to not include them -- it doesn't cost much, so miners can include them all in order to maximise fee revenue. But when there are more pending transactions than fit in a block, miners will sort by fee and include the biggest fees and reject the lowest fees. By growing blocksize, you avoid the situation where there are more pending transactions than…

Miners will likely omit transactions that offer a fee that is lower than their cost of mining (at least eventually). This sacrifices some small amount of revenue on the current block, but should lead to higher revenue over the long term (assuming their cost levels make bitcoin an attractive transaction system).

However, that would only become a problem after centralization, correct? Otherwise, it would require a concerted effort by most/all miners to take the same approach, rather than competing for staying power etc.

Important point about this debate:

* There is not the organic transaction growth for this to even be a problem, and there is no evidence there ever will be. Bitcoin's only real-world use case is illicit goods.

* Even 20MB blocks would be susceptible to a cheap spam attack like the DDOS "stress test" a few weeks ago.

This is the quintessential bikeshed: a fight to the death for insanely low stakes.

Bitcoin died in March 2014, with Mt Gox. Everything since then has been fussing over the remains.

You could make mining more memory bound rather than compute bound, somewhat reducing electricity costs and requiring bigger upfront investments (in DRAM chips). This also vastly reduces the performance gap between commodity and custom mining hardware.

I think the 400 Million[1] in venture capital alone can disqualify this statement.

That would surely be "speculation on future real-world use cases". Which isn't nothing, but isn't present real-world use cases.
