key format from `ag-chain-cosmos tendermint show-validator` not compatible with init cli

[dckc]

@michaelfig is this as-designed? If so, I guess we at least need to update the validator guide...

ag-chain-cosmos tendermint show-validator
{"@type":"/cosmos.crypto.ed25519.PubKey","key":"QkK5uJYlRfjgR8vNfW4Srcy0xUz1lfgxpPmoSd2E0/Y="}

Pulled the genesis file and config from the wiki: https://github.com/Agoric/agoric-sdk/wiki/Validator-Guide-for-Devnet

server_name: ag-cosmos-server
version: 0.26.10
commit: 65cec90b0
build_tags: ',ledger'
go: go version go1.15.7 linux/amd64

The chain syncs up fine to the last block, however when I'm trying to initialize our validator (with either a restored key or new key) it doesn't take the new format.

What specific command fails? What error message comes out?

Some more info for debugging purposes below: Fully synced:

Imported my previous keys:

Get the public key from the current node I noticed a different key type and key format here

# ag-chain-cosmos tendermint show-validator | jq
{
  "@type": "/cosmos.crypto.ed25519.PubKey",
  "key": "QkK5uJYlRfjgR8vNfW4Srcy0xUz1lfgxpPmoSd2E0/Y="
}

And last but not least trying to submit the create-validator tx which fails on the pubkey part

# ag-cosmos-helper tx staking create-validator \
   --amount=50000000ubld \
   --broadcast-mode=block \
   --pubkey="QkK5uJYlRfjgR8vNfW4Srcy0xUz1lfgxpPmoSd2E0/Y=" \

This makes me believe either something is wrong with my binaries or pubkey format. I used the following config files:

• Genesis: https://devnet.agoric.net/genesis.json
• Network-config: https://devnet.agoric.net/network-config

you can use --pubkey=$(ag-chain-cosmos tendermint show-validator)

total string instead of only pubkey value

Err.. that's the exact same value as I posted under "Get the public key from the current node" of my previous message so that results as expected in the same error:

# ag-cosmos-helper tx staking create-validator \
   --amount=50000000ubld \
   --broadcast-mode=block \
   --pubkey=$(ag-chain-cosmos tendermint show-validator) \

I didn't had any issues updating my node to agorictest-17 and I used the same deployment for devnet. What I will try to do tomorrow is a full redeployment of my devnet node together with running the validator set with a fresh keypair. This way we can be absolutely sure whether there is something wrong with my setup or the agoricdev-3 release.

[dckc]

any chance shell quoting is a problem here?

try --pubkey="$(ag-chain-cosmos tendermint show-validator)"?

Same result but ty for the suggestion. I will start with a fresh keypair tomorrow on a freshly synced node to see if it is on my end or not.. Will keep ya'll posted here.

Error: invalid character 'Q' looking for beginning of value

This is really bizarre, as it is a JSON parsing error (it's looking for an object beginning with {, but instead is parsing something that begins with Q). Can you try inlining the total, unaltered output of ag-chain-cosmos tendermint show-validator?

Like this (I needed to escape the output with ', or the shell would butcher it):

...
  --pubkey='{"@type":"/cosmos.crypto.ed25519.PubKey","key":"QkK5uJYlRfjgR8vNfW4Srcy0xUz1lfgxpPmoSd2E0/Y="}'
...

That did the trick @michaelfig ! Although I'm pretty sure I still had some old traces in the .ag-chain-cosmos directory. After spinning up a new fresh node, with a new fresh deployment of the Agoric Devnet 3 binaries, a new fresh keypair and inlining the total, unaltered output of ag-chain-cosmos tendermint show-validator it worked:

...
  --pubkey='{"@type":"/cosmos.crypto.ed25519.PubKey","key":"hSvi1j/3R0JbfA3lo5fOPwTRxOCcRa671J462rSzXJw="}' 
...

We are back up and running: https://devnet.explorer.agoric.net/validator/agoricvaloper16hlhqxnn5qkp2rwec2s3j3j0lu79sv7xz6whgu

[dckc]

So we just need to update the docs. Oh... in fact, I see the testnet guide was already updated in this regard:

https://github.com/Agoric/agoric-sdk/wiki/Validator-Guide-for-Incentivized-Testnet/_compare/dc4a6b2659765667905093ef8d108b34512396d5...34670f96f8d60bfec1d3778350efdedeb833e6d8

I updated the devnet guide likewise: 5f8dd82
