Remove genesis id

[zeldovich]

I don't think this is necessary or a good idea. It's not necessary because genesis ID is already optional and doesn't have to be included in transactions. It's not a good idea because genesis hash (the other way of identifying which chain a transaction belongs to) isn't directly human-readable, and genesis ID provides a human-readable sanity-check that users can perform when verifying a transaction they're about to sign.

@derbear can you jump in here?

[derbear]

It's not necessary, but it adds complexity to have two different ways of isolating blockchains and also to transaction verification. I would rather get rid of genesis ID and instead map the genesis hash to a human-readable string (like we do for mnemonics).

[zeldovich]

Do we know if there are pre-signed transactions for future rounds that include genesis ID?

[ian-algorand]

We don't know the answer to Nickolai's question. Maybe @Priegle or @ejbaran would know?

[updated]
Yes there are. But could we remove it and make the change backwards compatible for transactions that have it? It is nice to be able to inspect a transaction and see the human readable format but not necessary.

[derbear]

It's already backwards-compatible, so making this change would lose us the backwards-compatibility. It looks like we'll need to maintain support for genesis ID then.

(Sounds like we won't/shouldn't fix. If I'm wrong, please re-open.)
