Hi Yanmaani,

> Unfortunately, this isn't really possible. If they did that, you could get consensus splits. This is why all the other stuff is so important - if Bitcoin is subverted via soft-fork, you *can't* just run your own fork.

I am aware of this problem however looking for solutions or workarounds. Is it possible to have one library for things related to consensus which is used by all full node implementations? There are lot of other things in any full node implementation apart from consensus related code.

> This is all about the money - it's easy to have people be independent when their source of money is independent. But nobody's crazy enough to bite the hand that feeds them, and you couldn't really build a system on that basis. Our best hope is gentle hands, or contributors wealthy enough not to have to care.

Sorry neither I agree with this nor its "all about money" for me. I am assuming there are few others as well with similar thoughts.

I had shared few reasons why someone might contribute to Bitcoin Core: https://bitcoin.stackexchange.com/a/108017/

> Isn't Bitcoin already plenty distributed? Funding people in under-represented countries seems to me like a textbook exercise in 'box-ticking, but moreover, I'd frankly rather have reasonably well-off guys from Western Europe/America who have the financial backbone to not worry that much about attacks to their funding, than mercenaries who have to follow orders or get fired. Even if they're from West Uzbekistan.

Sorry I don't agree with this approach. Its not about 'box-ticking' textbook exercise but to make the attacks more difficult by any governments or people with malicious intent. Few years back when I was in college and Tor wasn't as famous as it is now, we used normal socks proxies for pentesting. My mentor Godzilla had suggested us to use IP of different countries not because it is some textbook exercise but it helps when someone tries to trace your requests. Similarly, if we have people from different countries in different full node implementations as maintainers it will be difficult for people to try crazy things.

> See above. Bitcoin Knots isn't really independent.

I understand there are other implementations like btcd, bcoin, gocoin, libbitcoin, bitcore etc. and Knots is a derivative of Core. However there are lot of differences and it changes your experience as a user while running node and using it for different things. I have mentioned few things in the medium post shared in last email.

> You could also look into a system like Monero's CCS.

Yes I like it and suggested once in bitcoin.org repository even though it can be done by anyone as there is no official website for Bitcoin: https://github.com/bitcoin-dot-org/Bitcoin.org/issues/3545

The money still has to enter the system somehow.
