To generate the genesis file for Gaia-7002, we exported the state from Gaia-7001, at height 24570 where it halted. The current version of gaiad has a [bug](https://github.com/cosmos/cosmos-sdk/issues/1799) in gaiad export, but we were able to use a [workaround](https://github.com/cosmos/cosmos-sdk/pull/1800) to successfully export the state. ([state.json](https://gist.github.com/jlandrews/8326a496fe3eb49527d88965d9cda850))

Due to bugs in gaiad v0.22.0, there were some inconsistencies in the state which we corrected.

[Builder script](https://gist.github.com/jlandrews/bd688892b369ef77edb3ad7255bb22d8)  
First we load the exported state.

```auto
import json
from hashlib import sha256
from base64 import b64decode

j = json.loads(open("7001state.json","r").read())

```

Then we removed validators who never signed blocks on Gaia-7001. This should help with time to startup of the chain and speed of consensus.

```auto
#validator addresses which hubble lists as being bonded validators but never signed a block
pks = ['28d64d33cd086452e491becfc15f3d31054db144', '26cf59b48aa6ff3a5126330782090b19bd3b0e87', '1e1a2486dce3b96e08f41d313908088ad33ed491', '1866433301a542afd800b971d6390551088a0903', '10ddf9c6aaf8e6f91f33a4fae3ebeab3c98136d2', '00122e5e691286ac03220fcee3ebec038067dded', '60229e2e273297fe00219e46dffb8f76844cdef9', 'd9e215abd1d680db4d60f3b347a07f949ea5242a', 'e33184c1eab6fb7c6ccb893963e8534c277fa842', 'd9bb73add5962326c5b8c36494dac1c3d7425db5', 'cc4c1d46ddba0912e9d6e4dd1f4a0897a945c68c', 'b3cec3cbafba428bf33fd2204e11ca2232426593', '9a03741063366e11ec0347f6c80a2891c799003f', '5a6b67f68591404c5079bebd7a6b7e046779d3b6', '4b75e0191ab777afb6787b94e256388e78d6a910', '3e504d10079dc278960c0f214235b840e23392b2', '52b590a0de161917dfa8215f990506c4df7a9d0d', '09f1395bfcdb45aa6f09cde85aa8b69246131962', 'ebcaa6886da3c8ac73cfdf8fea26e8d9b14b4e4e']

#remove validators who never came online according to hubble
j['app_state']['stake']['validators'] = [vi for vi in j['app_state']['stake']['validators'] if sha256(b64decode(vi['pub_key']['value'])).digest().hex()[:40] not in pks]
#filter out bonds to no longer existing validators
j['app_state']['stake']['bonds'] = [b for b in j['app_state']['stake']['bonds'] if b['validator_addr'] in [v['owner'] for v in j['app_state']['stake']['validators']]]

```

Due to a [bug](https://github.com/cosmos/cosmos-sdk/issues/1666), validators in Gaia-7001 were being listed as unbonded in the state, even though they had voting power. Also fixed the “do-not-modify” setting.

```auto
#set bonded status and fix do-not-modify flag on validators
for v in j['app_state']['stake']['validators']:
    desc = v["description"]
    for k,dv in desc.items():
        if dv == "[do-not-modify]":
            dv = ""
        desc[k] = dv
    v.update(status=2, description=desc)

```

We also added a validator entry for Shapeshift.

```auto
#adding a validator for shapeshift
j['app_state']['stake']['validators'].append({
  "owner": "cosmosaccaddr1ztc70khr9aghgwmuxap5y9ufavpxutjtkvhpe7",
  "pub_key": {
    "type": "tendermint/PubKeyEd25519",
    "value": "7vURd1EqPVfI/1viF/+LNm9lwaBAN/tSuoJ+Od972z0="
  },
  "revoked": False,
  "status": 2,
  "tokens": "100",
  "delegator_shares": "100",
  "description": {
    "moniker": "Project Bohr",
    "identity": "",
    "website": "",
    "details": ""
  },
  "bond_height": "0",
  "bond_intra_tx_counter": 0,
  "proposer_reward_pool": None,
  "commission": "0",
  "commission_max": "0",
  "commission_change_rate": "0",
  "commission_change_today": "0",
  "prev_bonded_tokens": "0"
})
j['app_state']['stake']['bonds'].append({
  'height': '0', 'validator_addr': 'cosmosaccaddr1ztc70khr9aghgwmuxap5y9ufavpxutjtkvhpe7', 'delegator_addr': 'cosmosaccaddr1ztc70khr9aghgwmuxap5y9ufavpxutjtkvhpe7', 'shares': '100'
})

```

Now that the data in `app_state` has been updated, we need to write the set of validators back to the object that gets passed to tendermint to start the chain.

```auto
#update main validator section to match validators from state machine
j["validators"] = [{"pub_key":v["pub_key"], "power":v["tokens"], "name":v["description"]["moniker"]} for v in j["app_state"]["stake"]["validators"]]

```

We also recalculated the totals for bonded/loose tokens, which were not properly updated to reflect the steak given to the faucet in Gaia-7001.

```auto
coinsToMap = lambda x: type(x)==list and {c["denom"]:c["amount"] for c in x} or {}

#update pool total values to be accurate
j["app_state"]["stake"]["pool"]["loose_tokens"] = str(sum([int(coinsToMap(a["coins"]).get("steak",0)) for a in j["app_state"]["accounts"]]))
j["app_state"]["stake"]["pool"]["bonded_tokens"] = str(sum([int(v["power"]) for v in j["validators"]]))

```

Finally we set misc parameters and wrote the json back to a file.

```auto
#set chain id and timestamp
j["chain_id"] = "gaia-7002"             
j["genesis_time"] = "2018-07-24T08:00:00.123456789Z"

open("7002-genesis.json","w").write(json.dumps(j, indent=2, sort_keys=True))

```

[Genesis file](https://gist.github.com/jlandrews/e7f109227ceadbc54d4dbfaf1637ccdb)

While the genesis file has been created, we’re still waiting on a final release of the software before we officially start Gaia-7002. So please stay tuned.

Can we assume we’re in the genesis file if we were bonded at block 24570?

Yes, assuming your validator was live at some point.

Heads up to anyone who downloaded the genesis file already, there was a minor error. There was a typo of “chain-id” that should have been “chain\_id”. It has been fixed now, in both the script and the resulting json file.

Awesome job. Could you also remove all instances of “[do-not-modify]” in the validator descriptions. It seems that in case it says “[do-not-modify]” their the owner is not able to update the values.

could you remove “cosmosaccaddr1arlpxs2ftf5hgetqxxkvd7mqdc28mmaqclyv4y” from the genesis? this is mine and i lost my private key of this.

Nice work.

Could you please remove this Certus.One validator: VBVHOLnWGptY26J0wqXoZI2Dnu96pccMb08zlsaxPCQ=  
and assign the 100 power to our new: 0vUHZTzJhnVDh7KJfuGt9g1uDsy0DK3BCQurhngwVos=

That would go with transferring the tokens of cosmosaccaddr1gq0qecxs8xdaarrqxxazwavwxm7qz5jzs5anvt to cosmosaccaddr1yqq6up8zyakmf6t7gg5txnyatqakj7ckkt8jfu

That’d be awesome.

can u please increase steak for kochacolaj to 100? i unbonded 50 but couldnt claim then rebond them due to a bug. suyuuu had the same problem - i dont know his amount. you see [https://figment.network/cosmos/hubble/gaia-7001/validators/1E9CE94FD0BA5CFEB901F90BC658D64D85B134D2](https://figment.network/cosmos/hubble/gaia-7001/validators/1E9CE94FD0BA5CFEB901F90BC658D64D85B134D2) that i unbonded and had maturity while 7001 was healthy. thx

Updated main post after changing script again. Previously forgot to track bond values to match updated validator state. We will be releasing the final / official genesis file through the SDK repo as usual I believe, so please don’t try to use the one posted here, it’s just for demonstration / transparency purposes.
