Upgrade to Akashnet-2

Akashnet-2 Upgrade Procedure

What validators need to do before the upgrade time?

  1. Verify you are currently running the correct version of Akash
$ akashd version --long
name: akash
server_name: akashd
client_name: akashctl
version: 0.8.3
commit: 11a6e4dfba545073f79732088735f93a5408995c
build_tags: netgo,ledger,mainnet
go: go version go1.15.5 linux/amd64
  1. Set halt-time to ensure your validator node stops at the right time and date: March 08 2021 at 1500 UTC.
$ perl -i -pe 's/^halt-time =.*/halt-time = 1615215600/' ~/.akashd/config/app.toml

or you can manually update app.toml using nano or vm

  1. Stop your akashd binary or systemd process
  2. Restart your akashd binary or systemd process

Instructions for upgrade, after the node stops (i.e., after 1500UTC on 8th March, 2021)

  1. Stop your akashd binary or systemd process
  2. Check the last block height signed

Check the last block height signed by your validator:

$ cat ~/.akashd/data/priv_validator_state.json | jq '.height'

Take the state export from this height (decision on the final height will be coordinated on the mainnet-validator discord channel):

  1. Export the akashnet-1 state
akashd export --for-zero-height --height <height> > old_genesis_export.json
  1. Fix migration issue by executing following command (This is yet to be fixed on cosmos-sdk: cosmos/cosmos-sdk#8776)
cat old_genesis_export.json | jq '.app_state.auth.accounts= [.app_state.auth.accounts[] | if (.value.public_key!=null and .value.public_key!="") then (.value.public_key.value= (.value.public_key.value | if type=="string" then . else (.threshold = (.threshold| tonumber)) end)) else . end ]' > old_genesis_updated.json
  1. Verify the SHA256 of the (sorted) exported genesis file:
$ jq -S -c -M '' old_genesis_updated.json | shasum -a 256

Compare this value with other validators of the network over on #validators-mainnet on the discord server. It's important that everyone can create the same genesis file export.

HASH: [TBD]

  1. Install Akash v0.10.1

Note: Building the new binary requires Go 1.15+

git clone https://github.com/ovrclk/akash
cd akash
git checkout v0.10.1
MAINNET=true make install
  1. Verify you have the correct version:
   $ akash version --long
   name: akash
   server_name: akash
   version: 0.10.1
   commit: c39715e1f9c13ec85eefbfb295031e995db45591
   build_tags: netgo,ledger,mainnet
   go: go version go1.15.5 linux/amd64
   build_deps:

Note: akashd and akashctl are merged into a single binary, akash now.

  1. Migrate exported state from the current v0.8.3 version to the new v0.10.1 version:
$ akash migrate v0.40 old_genesis_updated.json --chain-id=akashnet-2 --genesis-time 2021-03-08T15:00:00Z > 040_migrated_genesis.json
  1. Migrate command adds a warning to the exported file regarding max_bytes in the evidence module which we will modify in the next step. Remove the warning:
$ sed -i  '/Warning/d' 040_migrated_genesis.json
  1. Update the evidence params as below:
$ sed -i 's/{"max_age_duration":"172800000000000","max_age_num_blocks":"100000"}/{"max_age_duration":"172800000000000","max_age_num_blocks":"100000","max_bytes":"1048576"}/g' 040_migrated_genesis.json
  1. Add IBC and Akash parameters to the genesis file:
$ cat 040_migrated_genesis.json | jq '.app_state |= . + {"ibc":{"client_genesis":{"clients":[],"clients_consensus":[],"create_localhost":false},"connection_genesis":{"connections":[],"client_connection_paths":[]},"channel_genesis":{"channels":[],"acknowledgements":[],"commitments":[],"receipts":[],"send_sequences":[],"recv_sequences":[],"ack_sequences":[]}},"transfer":{"port_id":"transfer","denom_traces":[],"params":{"send_enabled":false,"receive_enabled":false}},"capability":{"index":"1","owners":[]}} + {"deployment":{"deployments":[],"params":{"deployment_min_deposit":{"denom":"uakt","amount":"5000000"}}},"market":{"orders":[],"leases":[],"params":{"bid_min_deposit":{"denom":"uakt","amount":"50000000"},"order_max_bids": 20}}} + {"provider":{"providers":[]}} + {"cert":{"certificates":[]}} + {"audit":{"attributes":[]}} + {"escrow":{"accounts":[],"payments":[]}}' > new_genesis.json
  1. Verify the SHA256 of the final genesis JSON:
$ jq -S -c -M '' new_genesis.json | shasum -a 256

HASH: TBA

  1. Creating a new home directory for akash
$ akash init <moniker> --chain-id akashnet-2
  1. Update the fast-sync option to v2 in config.toml
version = "v2"

  1. Make the following changes in app.toml

    State sync snapshots allow other nodes to rapidly join the network without replaying historical blocks, instead downloading and applying a snapshot of the application state at a given height.

[state-sync]

## snapshot-interval specifies the block interval at which local state sync snapshots are

## taken (0 to disable). Must be a multiple of pruning-keep-every.

snapshot-interval = 500

## snapshot-keep-recent specifies the number of recent snapshots to keep and serve \(0 to keep all\).

snapshot-keep-recent = 2
  1. Copying node_key.json and priv_val_key.json and new genesis to the new home directory (Only applicable for the ones who are using the file-based FilePV implementation for their consensus keys)
$ cp .akashd/config/node_key.json .akash/config/node_key.json
$ cp .akashd/config/priv_validator_key.json .akash/config/priv_validator_key.json
$ cp new_genesis.json .akash/config/genesis.json

  1. Add Peers to .akash/config/config.toml

  2. Update systemd Edit your systemd file to use akash instead of akashd and also rename the service file to akash

  3. Start your validator

sudo service akash start

Note Migrate keys or recover using mnemonic (For all non-ledger users) akashctl keys export <keyname> akash keys import <key_name> <key_file_json> or akash keys add <key-name> --recover
