Allow querying for genesis transactions on height 0

[faboweb]

Summary

It would be nice to be able to query the genesis block as height 0.

Problem Definition

We can query blocks, validatorsets, transactions and others by block height. For the block 0 (genesis block) we can't.

Proposal

It would be nice to unify this experience by indexing the block, transactions and others as height 0 even if they miss some properties.

Why can't you get block 1?

[faboweb]

It's not the genesis block isn't it? So I wouldn't see the genesis transactions.

[fedekunze]

we can query the genesis txs using the /genesis rpc endpoint and parse the gen_txs property

[alexanderbez]

Great! Can we close this issue then?

[fedekunze]

we could do something like /txs/genesis or /txs?tx.height=0 to get the txs, bc technically it's not a block

[faboweb]

I think the biggest case is genesis transactions. So I change the title.

@fedekunze why not make /txs?tx.height=0 parse genesis and pull out the gentx? (i.e. sugar)

[faboweb]

That's what he is suggesting I think ;)

[fedekunze]

@colin-axner want to take on this one when you have time?

The scope would be:

• pulling the gentxs from the genesis state and return them on a query if heigth=0

For the next iteration, we could add events for each of the genesis txs to make them queryable
