What am I missing?

Until I find time to actually read all the code, how is this block size limit really set?

This article mentions blocks at 750KB, yet there is mention of a 1MB limit?

https://themerkle.com/bitcoin-core-developer-lays-out-scalability-roadmap-based-on-segregated-witness-segwit/

But in the code I find this as the block size limit? on line 18.

https://github.com/bitcoin/bitcoin/blob/v0.14.0/src/policy/policy.h


So how is the limit 1MB?

Why are hardware kludge workarounds being implemented in software? None of this makes any logical sense to me.

Thanks in advance for an explanation.

From ASICBOOST post:

I ran across NSA research publications about how to perform this type of optimization a while back along with institution research findings. All I see is a hardware implementation that was patent (pending). Since they (NSA) came up with the algorithm, I figured they might have some expertise on the subject along with publications. TAEUS in Colorado Springs, CO can perform RI on the miner device/IC, lot's of research done there and Palo Alto, CA.

I have to say, this is like nerd days of our lives, need some butter for my popcorn!


What I find interesting is a 9 month delay between the original discussion and the release of this draft BIP by Blockstream CTO Maxwell.

Some comments about taking old coins through forfeiture by the mere fact they haven't moved for some time seems to indicate a 'long con' with all this brouhaha.

Was BIP16 the introduction of malleability?

So this is the block size limit here ...

Experimenting with example.c from libblkmaker now.

This is the first study to systematically investigate key cryptocurrency industry sectors by collecting empirical, non-public data. The study gathered survey data from nearly 150 cryptocurrency companies and individuals, and it covers 38 countries from five world regions. The study details the key industry sectors that have emerged and the different entities that inhabit them.

Some of the key findings include the following:

The current number of unique active users of cryptocurrency wallets is estimated to be between 2.9 million and 5.8 million. The lines between the different cryptocurrency industry sectors are increasingly blurred: 31 per cent of cryptocurrency companies surveyed are operating across two cryptocurrency industry sectors or more, giving rise to an increasing number of universal cryptocurrency companies. At least 1,876 people are working full- time in the cryptocurrency industry, and the actual total figure is likely well above two thousand when large mining organisations and other organisations that did not provide headcount figures are added. Average security headcount and costs for payment companies and exchanges as a percentage of total headcount/operating expenses are similar, but significantly higher for wallets.
