Run an Archway node

The Archway Full Node will act as the source for the KYVE protocol validator and is required. You can either run the Archway node on the same machine with the KYVE protocol together (recommended) or on a seperate machine.


Due to very specific requirements, an additional validation layer, accessibility as well as to prevent slashes, it is strongly recommended to run an independent data source node. API providers should be avoided and have already led to critical problems in the past.

Install Archway full node

The Archway binary with the version v1.0.1 has to be installed.

You can follow the official installation instructions here or download the binary directly from here.


If you are building from source please use the specified go version in the go.mod file, else there is the danger of receiving vote slashes.

For archwayd v1.0.1 it is go19

You can verify the successful installation with

./archwayd version

After the successful installation, you need to set up the archwayd config. First choose a moniker and initialize everything:

./archwayd init <your-moniker> --chain-id archway-1

To download and setup the genesis file execute the following command:

wget -qO- | zcat > ~/.archway/config/genesis.json

To enable the start of the syncing process, a seed node needs to be added into


seeds = "3ba7bf08f00e228026177e9cdc027f6ef6eb2b39@"

You can also add persistent_peers from Polkachu to ensure that you will actually find peers where you can sync with the network:


Due to the size of the block_results response, it is required to set the following in your ~/.archway/config/config.toml:

timeout_broadcast_tx_commit = "120s"

For efficient pruning, the following settings are recommended to decrease the disk usage:



indexer = "null"


pruning = "everything"

index-events = [""]

Finally, the node can be started:

./archwayd start --x-crisis-skip-assert-invariants

To be able to perform upgrades automatically, it is recommended to use the cosmovisor. How to set it up can be found here.

To start the Archway node with the cosmovisor, run:

cosmovisor run start --x-crisis-skip-assert-invariants

Verifying the completed node setup

After the successful start of the node you have to sync blocks until the latest summary of the pool is reached. For example if the latest pool summary is 1,000,000 you can check if the node has synced the blocks until that height with:

curl http://localhost:26657/block?height=1000000

If it returns a valid block response you can continue with starting the actual KYVE protocol validator and start participating in the validation and archival process.


To save storage space you can start pruning blocks manually after they have been archived by the pool since after that they are not needed anymore.
