Firstly, I just want to say, what a beautiful piece of software you have made Piotr! I never heard about it and I had already looked at btcd and as soon as I saw yours running I wanted no more of btcd.
I am forking the code quite heavily, a bit more than a regular altcoin fork, the reward formula will be based on exponential decay, and because of this also I can eliminate transaction fees, but I have to massively increase the precision of the coin denomination (I think it will have 12 whole number places and 64 decimals) and I am switching out siphash for highwayhash, and secp256k1 for ed25519 and a block time of 1 minute and bigger blocks.
I noticed that the code makes golint put a lot of squiggly green lines on my VScode editor display, I suppose Go's idiom has changed significantly since 2013. I will be reworking a lot of the code, but compared to working with regular C++ based cryptocurrency nodes your code is a pleasure to read, and the web interface is beautiful, and so informative. I will be watching the repository for when you complete segwit multisig, and probably it will be a month or two before I am testing it. I will also probably add a gRPC interface to it to make it easier to plug into other applications also.
I am quite sure that it will be greatly changed compared to the original but you will be most welcome to use any changes or additions I make outside of the core protocol parts. I think the web interface could be expanded to the point where it is as feature laden as bitcoin-qt, at option, with a nice Angular/Material skin on it.
In case you are concerned about my intended use, it will not be for a business, but rather as a base token for a larger protocol based on the SporeDB BFT database replication protocol, including a DEX, forum, chat system, git repository and hopefully from there it becomes a way for programmers to get paid without having really a boss (using a reputation system and rewards distribution similar to Steem). I thought it would be a nice, and fair way, to make it open yet provide enough possible money available for developing my larger project further. I am changing the proof of work algorithm also, and I have mostly designed the underlying sort/search protocol for a variant of Cuckoo Cycle, that massively exploits data cache locality and memory block alignment which potentially could mean not much possible improvement compared to a CPU because of cache memory being a very large component of the cost of production of processors. So hopefully it will be a coin that people can mine without sudden increases in network hashrate as recently happened to Sia, Monero and all the equihash coins.
Anyway, very nice work, and I wish more programmers wrote code like you, it would make the cryptocurrency space so much more vibrant.
You may have already noticed, if github tells you when someone has forked your repository, but this is what I have done so far, though I have been busy with other work for a few days and haven't finished yet writing the ultra precision math library that will be needed for my changes, hopefully tomorrow I can start again.
