How to verify Genesis

Requirements

  1. A synced cosmoshub-3 node with pruning default (backup here)
  2. Latest juno binary on branch zaki-airdrop
  3. Exchanges list JSON file

Parameters

You can find a list of parameters in the following table parameters.md

Procedure

Init JUNO the genesis file

First we need to clone Juno repository, checkout the mainnet branch v1.0.0 and compile. Make sure to have go at version 1.16 or above

git clone [email protected]:CosmosContracts/juno.git
cd juno
git checkout v1.0.0
make install

Delete the old .juno directory

NB This will delete your validator private key, and all your configurations. So it from a development machine.

rm -rf ~/.juno

Now we can start forging the genesis file, let's start using the traditional cosmos-sdk init command

junod init <moniker> --chain-id juno-1

An empty genesis.json file will be created in your .juno/config directory.

Export cosmoshub-3 snapshot

First we need to export state from the hub3 snapshot, if we have a synced node is quite simple with the following command

gaiad export --height 5200790 > cosmoshub3.json

a file named cosmoshub3.json will be generated containing the state of Cosmos Hub on block before the stargate upgrade.

If you don't have a synced node, you can download the export from here cosmoshub_3_genesis_export.zip

Generate balances snapshot

Now we need to parse all the balances of cosmoshub 3 and generate a file with filtered accounts, to do so run the following command:

junod export-airdrop-snapshot uatom cosmoshub3.json exchanges.json juno_out.json --juno-whalecap 50000000000

A new file juno_out.json containing all the airdropped balances will be generated.

Some useful statistics will be printed in the command line:

cosmos accounts: 78254
atomTotalSupply: 268335648775167
total staked atoms: 179033710700329
extra whale amounts: 118667082985153
total juno airdrop: 30663193590002

Add airdrop accounts & community pool

Now we can add all the airdrop accounts generated in the juno_out.json file before, running the following command

junod add-airdrop-accounts juno_out.json ujuno 20000000000000

It may take from 30 minutes up to a couple of hours, depending on your system specs.

Add vesting and multisig amounts

To add the core team and multisig vesting accounts we developed an utility to do so genesis-utils, it's enough to clone that repository and run the following commands:

    npm install
    npm run add-vesting-account juno1a8u47ggy964tv9trjxfjcldutau5ls705djqyu fulltime_periods.csv ~/.juno/config/genesis.json
    npm run add-vesting-account juno17py8gfneaam64vt9kaec0fseqwxvkq0flmsmhg fulltime_periods.csv ~/.juno/config/genesis.json
    npm run add-vesting-account juno130mdu9a0etmeuw52qfxk73pn0ga6gawk4k539x partime_periods.csv ~/.juno/config/genesis.json
    npm run add-vesting-account juno18qw9ydpewh405w4lvmuhlg9gtaep79vy2gmtr2 fulltime_periods.csv ~/.juno/config/genesis.json
    npm run add-vesting-account juno1s33zct2zhhaf60x4a90cpe9yquw99jj0zen8pt fulltime_periods.csv ~/.juno/config/genesis.json
    npm run add-vesting-account juno190g5j8aszqhvtg7cprmev8xcxs6csra7xnk3n3 multisig_periods.csv ~/.juno/config/genesis.json

Set Params

    npm run set-params ~/.juno/config/genesis.json

Compare SHA256 Sum

Now you can compare the SHA256 hash of the provieded genesis.json with yours.

$ jq -S -c -M '' juno-1/pre-genesis.json | shasum -a 256
2341157ce2aec7700b523b2313de19b3203afdf204d555472e29e79fef3e39a1  -


$ jq -S -c -M '' ~/.juno/config/genesis.json | shasum -a 256
2341157ce2aec7700b523b2313de19b3203afdf204d555472e29e79fef3e39a1  -
