This is a new release for CertiK Chain with various different features and bug fixes. The 0.8 chain data was copied over at height 1343300.

To upgrade to the new binary, there are two options.

1. Startup from genesis (WARNING: due to high load of data in the genesis file, this method will require more than 8GB of RAM to follow.)

   1. Stop the running certik daemon (killall certikd).
   2. download the genesis.json file and replace config/genesis.json. (by default it is located in ~/.certikd/config/genesis.json.
   3. run certikd unsafe-reset-all.
   4. copy content in persistent_peers.txt to config/config.toml, under persistent_peers = "<paste content here>".
   5. run certikd start with the new binary.
   6. Note since the genesis data is big, the startup might take a few minutes.

2. Starting from a pre-loaded state at height 1 (takes up to 2GB of memory)

   1. steps 1 through 4 should be the same with above.
   2. After copying persistent peers over, download data.zip
   3. Unzip data.zip, and copy over the content of the unzipped folder under data/ directory.

Note that it might take up to 5 minutes to load and commit the first height when starting off from genesis.

If you were a validator before the update, you will have to unjail yourself using the command certikcli tx slashing unjail.
It is crucial you run certikd unsafe-reset-all to prevent any unexpected behavior after you upgrade.
