DISCUSS: Chain params for 0.1.1 network

[hleb-albau]

https://github.com/cybercongress/cyberd/blob/chain_params/docs/overview.md
Here, I collect all params into a single place and create a small description about cosmos-sdk modules flow. Please, ask as many questions as you can, we will improve this doc.

Also, here I propose values on params.
I suggest increasing block size to 5s. Currently, on a small network, it takes about half a day to catch up the empty chain.

146 - Because of Dunbars number
1 second - Because with 5 seconds we will have pretty slow thing

1. Dunbars number not really related to validators problems. Cosmos-hub will slightly increate year by year validator set, starting 100 to 200 by 10 years.
2. We should choose the trade-off between validator requirements and block generation speed. Currently, if we choose 1 sec, then all validators should have a very good internet connection to not miss block signing(by miss I mean not being offline, but just delayed sign). There is MinSignedPerWindow param, that set minimum successful block signs for SignedBlocksWindow. With unstable validators(our case right now), we should set it to higher value, say 2/3. In other case, network will eventually stop, cuz there are no 2/3 block signs. If we chouse high MinSignedPerWindow, than regular validators will be jailed frequently(we already see it on 0.1.0 testnet). That can scare away initial intusiasts. Guys from polka, said that for more than 20 valdiator, currently it is not really possible to have stable network with 1 sec block for a long period.

It's because the network runs without money. I bet it is possible in our setting

Overall, I would discus with Valera first some principles of the network we are building. They define parametrs
