How much block size we need to replace visa transactions?

[HostFat]

is really based in human desires or to mathematics? Satoshi really create a system to trust humans or to remove humans for the trust systems?

It's mainly based on human desires, without there weren't miners and then no Bitcoin.
This is the real magic.

If you wrongly touch them (their incentives) you are really going to break the core of the system.

i dont think and a vote is a solution. We need to keep trust to mathematics like bitcoin do and not to the human desires

true.. but if lets say its fully automated to increase the limit, if lets say 4 blocks in a row are over limit X. then some tx spammers can abuse that to force the limits up..

so i still prefer my manual tweaker feature so i can cut them off if the increase was due purely to tx spammers flooding generous block rules. or increase it now that i see alot of people are open to 2mb as an acceptable increase.

after all the purpose of the limit in the first place was to prevent tx spamming.. so while i now have my node at 2mb.. i dont have to worry about tx spammers trying to push generous block miners to 3.. as my node wont accept blocks over 2mb unless there is a big call for it.

so i prefer it to be a consensus decision to increase based on users opinion. but without having to then argue which dev team to then trust to implement that increase.. as people can do it themselves

for that i have say that first of all we need to find a solution to the root of tha drama we have today. And this root of the block limit is spam attack. I dont see a real solution to this problem

[chek2fire]

we dont need humans to decide what the block size will be but we need mathematics to decide for this

spam attack is not a big deal if limits are fixed(moving only by consensus).. the drama is mostly about which dev group to trust to have clean code..

but a totally unlimited system would be risky as spammers would push it as far as they can. so having a fixed limit that only increases based on consensus is better

sorry but it does need a human element..
maths cannot tell very much about the real world..
maths cannot tell very much about things that are not inputted into the equation... it requires an outside entity to input what is needed for maths to work

after all

without me telling you if it is add, subtract, multiply or divide... its just number..
maths is great but it cant solve everything unless its provided with everything it needs.

part of that is understanding the difference between genuine demand increase vs spam attacks which is best judged by humans.

part of it is knowing the capability of 90% of other users systems.. again some dont have 100mb internet. and so 2mb became the favourite to keep people happy.. vs growing exponentially purely based on maths would cause bandwidth bottlenecks as maths does not understand some outside limitations exist

The block size limit is not going to change in the near future. The 1mb block limit was put in place to stop people spamming. It is working fine at the moment but when more people use Bitcoin, then maybe it will go a bit higher.

My question is simple. How much block size we need to have transactions like visa or like paypal etc or to compare with all of them together? Is this real that we need to have a block size above 1gb only to have the visa transactions?
Is ever this possible to happen? And how many forks we need to have to get to this block size?
I think the fork system to correct the block size problem for transactions is in the wrong way. We all know that bitcoin was not creating to replace every day payment and we cant to do this unless we drop it decentralized system. Only with a big central database bitcoin can handle so many every day transactions.

This is like asking how many roads you need to build for cars to have the same passenger traffic capacity as subway. You will have layers and layers of road in the city that you barely can see the sun  

Similar to driving license, you must have enough IT expertise and security knowledge to directly use the blockchain to do transaction, and you must have enough money to buy a car and pay for the gas (only large transactions is feasible), so there will not be so many people use blockchain directly, they will rely on experts handle this for them

[Amph]

not even 32, visa is on the range of 2k per second, you have right now 3 per second with 1mb, so you do the math

you need 800x, remember that 7sec is a lie, we are much lower than that currently, because you need to consider the output and imput and multisig etc...

Yes  
Similarly I could say this: USA have the widest highways on earth, but they also have the biggest cars and trucks plus they have the worst drivers in the world. Come on they use bumpers to avoid car accidents at parking lots!

Anyway, in other countries those roads will be too much but in the US they are not enough. So what's the matter?

The HUMAN part is the problem.
