@fadeev I realize that this distinction between ignite account and appd keys is maybe not so deep, since we recently added the --keyring-dir flag in #2669.

For instance, giving the following blogd keys :

$ blogd keys list
- name: alice
  type: local
  address: cosmos1wzuums2e3t3jkz7ym4thjecype5352zds9h96d
  pubkey: '{"@type":"/cosmos.crypto.secp256k1.PubKey","key":"AjAuPBMEhuB/BVcJbYvnbsfh3GrQswod3OsiIOWyO/TC"}'
  mnemonic: ""
- name: bob
  type: local
  address: cosmos1l6twp8lkzskpch4wdej5gsee7tuhk9agypjxxa
  pubkey: '{"@type":"/cosmos.crypto.secp256k1.PubKey","key":"A/piEG8Yivahuib/AG8XOMUQB4r+YhfbaH8qJk/O9pT8"}'
  mnemonic: ""

I can query them with ignite account too :

$ ignite account list --keyring-dir ~/.blog/
Successfully migrated key alice.info.
Successfully migrated key bob.info.
Name 	Address 					Public Key 							
alice 	cosmos1wzuums2e3t3jkz7ym4thjecype5352zds9h96d 	PubKeySecp256k1{02302E3C130486E07F0557096D8BE76EC7E1DC6AD0B30A1DDCEB2220E5B23BF4C2} 	
bob 	cosmos1l6twp8lkzskpch4wdej5gsee7tuhk9agypjxxa 	PubKeySecp256k1{03FA62106F188AF6A1BA26FF006F1738C510078AFE6217DB687F2A264FCEF694FC} 	

And now I've just reproduced the problem a user has in #2773 !!! If I run blogd keys list after that, I got Error: Bytes left over in UnmarshalBinaryLengthPrefixed, should read 10 more bytes but have 152 😨

It seems like ignite account migrates the account from amino encoding to protobuf, but then blogd keys is no longer able to read them, that's annoying...

This is related to a migration of the keyring added in v0.46 (cosmos/cosmos-sdk#9695)

@tbruyelle good to know! 👍 It still might be a good practice to use the chain's binary for key management, but I will expand the description of this command in the following PRs.
