0.18.0

June 9, 2018

BREAKING CHANGES

• [stake] gaiacli query validator takes and argument instead of using the --address-candidate flag

Make lots of small cli fixes that arose when people were using the tools for the testnet.

  • basecoin start supports all flags that tendermint node does, such as --rpc.laddr, --p2p.seeds, and --p2p.skip_upnp
  • fully supports --log_level and --trace for logger configuration
  • merkleeyes no longers spams the logs... unless you want it
    • Example: basecoin start --log_level="merkleeyes:info,state:info,*:error"
    • Example: basecoin start --log_level="merkleeyes:debug,state:info,*:error"
• basecli

    • no account (query) subcommand
    • a few other random ones...

  • integrate viper, all command line flags can also be defined in environmental variables or config.toml
• genesis file
  • you can define accounts with either address or pub_key
  • sorts coins for you, so no silent errors if not in alphabetical order
• light-client integration
  • no longer must you trust the node you connect to, prove everything!

  • integrated key management, stored encrypted locally
  • tracks validator set changes and proves everything from one initial validator seed
  • basecli proof state gets complete proofs for any abci state
  • basecli proof tx gets complete proof where a tx was stored in the chain
  • basecli proxy exposes tendermint rpc, but only passes through results after doing complete verification

• CLI returns exit code 1 and logs error before exiting

0.3.0 (March 23, 2017)

BREAKING CHANGES:

• Remove --data flag and use BCHOME to set the home directory (defaults to ~/.basecoin)
• Remove --in-proc flag and start Tendermint in-process by default (expect Tendermint files in $BCHOME/tendermint). To start just the ABCI app/server, use basecoin start --without-tendermint.
• Consolidate genesis files so the Basecoin genesis is an object under app_options in Tendermint genesis. For instance:

{
  "app_hash": "",
  "chain_id": "foo_bar_chain",
  "genesis_time": "0001-01-01T00:00:00.000Z",
  "validators": [
    {
      "amount": 10,
      "name": "",
      "pub_key": [
	1,
	"7B90EA87E7DC0C7145C8C48C08992BE271C7234134343E8A8E8008E617DE7B30"
      ]
    }
  ],
  "app_options": {
    "accounts": [{
      "pub_key": {
        "type": "ed25519",
        "data": "6880db93598e283a67c4d88fc67a8858aa2de70f713fe94a5109e29c137100c2"
      },
      "coins": [
        {
          "denom": "blank",
          "amount": 12345
        },
        {
          "denom": "ETH",
          "amount": 654321
        }
      ]
    }],
    "plugin_options": ["plugin1/key1", "value1", "plugin1/key2", "value2"]
  }
}

Note the array of key-value pairs is now under app_options.plugin_options while the app_options themselves are well formed. We also changed chainID to chain_id and consolidated to have just one of them.
