Well if each block has to be signed with 50% of the banks that reduces trust by some degree, however this still can be done more efficiently with a relational database.

That seems to leave them with the same problem where a single bank can lie and cause problems.

Latency is one of the problems with regards to creating an economy of scale and centralization. It may actually work better to increase the block size by having 3MB blocks with 20 minute intervals or 1 hour blocks with 20MB caps, though tha

A smart contract is a contract that can be executed with the trust parameters you set, these parameters are less limited than typical contracts have since they don't have an inherent necessity to trust a government or even a counterpar

Surely they verify the PoW, otherwise it would be trivial to create a long chain and attack them.

Leap hours are probably acceptable, but at the point that you're only deviating by an hour every few millenia, can't it be safely accepted that the time has a different meaning and between generations it be accepted that 8PM means

As long as we have a standardized way of determining when leap seconds are going to happen, some authority determining and announcing, there shouldn't be problem. Leap years are predictable, but leap seconds can be accounted for a deca

This seems to be something that would benefit from standardization and modularity... Pausing for a second, going back a second in time or changing how long a second is all are hacks that are bound to cause some edge case failure somewhere.

You can cite industry improvements in the manufacturing process that companies say will effect the price at a certain point along with scientific developments and in general claims made by actual corporations.

I'm not sure I agree with the placement of debt. It is often the case that you can you off the debt, but the money invested properly could increase faster than the debt increases.

You check 3 characters, not 1, but like I said, 80^3 still isn't good.

They may be storing the three characters as a hash separately, not that that is much better.

It seems that people lost because they were either speculating blindly or had an algorithm that was working poorly. I don't see reason for these algorithms to be outlawed.

Yeah, these work great out of consensus systems. Please consider that you're working on a consensus system though. "Simultaneous" has no meaning. There are no means of instant communication, there is latency. There also is no

Yes, it is pointless for me to argue about an undefined system. If you mean to say that 67% of the validator set must sign every block, then you shouldn't argue with the premise that 100% must sign every block.

Bitcoin wallets can have their source code audited. A blockchain that you accept regardless of the fact that there is a taller one is not audited by definition.
