Now try to be biased and explain how vulnerable 10MB / 20MB blocks sizes will be to other attack vectors and why Satoshi never increased it to those levels from the start.

Satoshi never increased to those levels from the start, because they weren't necessary.

Here is a whitepaper for all the calculations you need.

Are there breakdowns or benchmarks which give an idea of how much faster a 2MB, 8MB or 20MB block size might be over current block size?

What if a 20MB blocksize only increased transactions to 10 per second.

 Huh

It would be nice to have some idea of how many transactions per second a block size increase would yield.

All things being equal, I would think there'd be a linear relationship between TPS and blocksize.
If 3 TPS is generally filling blocks up to 1MB, then we should get about 30 TPS for 10MB blocks.

Obviously size in bytes of transactions matters but no reason that would change... Slightly
longer time for block propogation shouldn't matter either as the 10min timeframe would still
stay the mean after difficulty adjustments.

Am I missing anything big?



Yea, you are quick to explain how "good" bigger Block sizes will be for Bitcoin. Now try to be biased and explain how vulnerable 10MB / 20MB blocks sizes will be to other attack vectors and why Satoshi never increased it to those levels from the start.

How long can you upgrade only the Block size to match transactions throughput equivalent to VISA and Mastercard?

I am curious to see your answer to this. ^smile^

Gavin did some testing with bigger blocks a while back.

There is much discussion on the topic of block size.

What is lacking in these talks is hard data.

Benchmarks, evidence, testing which conclusively demonstrate block size makes a difference in transactions.

The block size debate is a loose equivalent to debates geeks had in past years where some believed increasing RAM on a PC could make a big improvement in performance, while others held the opposing view; increasing RAM wouldn't make a noticeable difference in most cases.

The block size debate is like Intel vs AMD all over again.

We have benchmarks and testing that can quantify to a reasonable degree how Intel and AMD processors stack up against each other.

Where are benchmarks showing bitcoin unlimited or segwit have a legitimate claim to better transaction speed via increasing block size?

 Huh
