Wow, great write up. Excellent example of computer science fundamentals being used to tackle a novel problem.

I recently had to use the concept of table doubling to improve a system where rough estimation was being used to determine the size of a data structure. It certainly felt good to recall the concept of table doubling and design a system using it's concepts.

The flaws of ETH seem to show daily. The fact that this is a necessity to keep ETH flowing is a bad sign of things to come.

Bitcoin not blockchain.

Thanks, I basically did a brain dump on the README. I plan do do many more bounties like it in the future. Really glad it's made some traction.

Or neither Bitcoin nor Blockchain. The thing is, inflation is actually what keeps the entire economy moving. Deflationary currencies actively dissuade investment and lending. What would a loan even look like denominated in a deflationary currency? Lenders are incentivized not to give you the one, as their cash reserves appreciate risk-free.

Oh, and also, why trust this random ad-hoc group of self-appointed economists (the core dev team) over a selected group of professional economists with degrees an arms-length away from politics (the federal reserve)? None of it makes sense. If the core team wants to create more bitcoin they can. Just like the fed.

Inflation is not a bad thing - it's solely a regular haircut for unproductive capital. Nobody should be hoarding cash. They should invest. Salaries are indexed for inflation so they don't go down. This isn't rocket science.

Cryptocurrencies, and especially Ethereum, are truly novel innovations in computer science that cross many academic disciplines. The linked example is a great write-up. It’s sad that there is a vocal group, especially on HN, that knee-jerk hates everything blockchain related and wishes with their entire being for it to fail.

However, I think smart contracts are fascinating and wish more people would keep an open mind.

I don't understand how the fact that the author solved a novel problem and then posted a bounty points to "flaws of ETH". Could you elaborate?

Also, what do you mean by "Bitcoin not blockchain"?

by the way. I deployed the same thing on the KOVAN test network at this address (if people want to test their exploits for free first): https://kovan.etherscan.io/address/0xfbc23099a8bd0ce4227920d...

Your economics are all wrong. Ever heard of the Cantillon Effect? https://www.aier.org/article/sound-money-project/cantillon-e...

Blah, blah, blah. Take your inflationary currency if you really like it so much, no one really cares, and no one ever forced anyone to use deflationary currency (unlike fiat ones), which tells you where the the truth is.
