minimum staking amounts not explained in tutorial (formerly "stake is the only denomination that works for delegating")

[tuckermint]

Hi,

I tried to use this tutorial to make a chain with only one token.

First, I changed bond_denom in genesis.json to tuckeratom.
Then, I gave all of the genesis accounts 1000 tuckeratom.
Finally, I made a gentx using --amount 1000tuckeratom.

I collected the gentx and validated the genesis.json, everything looked normal.
But when I run nsd, I get "ERROR: error during handshake: error on replay: validator set is nil in genesis and still empty after InitChain"

This error does not appear if I use stake as the bond_denom and do the default gentx with 100000000stake.

But if I use stake as the bond_denom, I can't delegate tuckeratoms.

Has non-stake delegation worked for anyone else?

Thanks

@marbar3778 are you the lead dev for the tutorial?

Just a guy who try's to maintain it, but suppose to be mainly on tendermint, I'm flying tomorrow so will debug this on the plane

I tested it out and was able to get it running with denom: legends, here is my genesis:

If I start the chain with your genesis.json, then switch to mine, it will run.
If I start from scratch with mine, I get the error.

Here is my genesis.json:

I have to double check but it seems the amount Isnt great enough, can you put a couple 0's I think min_self delegation looks at 1 while bond amount is 1/1000 th

[tuckermint]

It worked with 100000000 tuckeratom.

Is the minimum amount explained in the tutorial anywhere?

If not, I guess it should be added to this part: https://github.com/cosmos/sdk-application-tutorial/blob/master/tutorial/build-run.md#running-the-live-network-and-using-the-commands

Especially since the nametoken amounts are lower than the threshold, so someone trying to test out staking with nametokens would run into this error.

--

I see here that min-self-delegation of 1 means 1000000uatom on mainnet: https://cosmos.network/docs/cosmos-hub/validators/validator-setup.html#create-your-validator

Is there a way I can define utuckeratom to be 1/1000000 of a tuckeratom?
Or is any custom token treated as the smallest unit of a larger, undefined token?

[alexanderbez]

This is a requirement of tendermint. See references:
