These instructions are for setting up a brand new full node from scratch.
First, initialize the node and create the necessary config files:
akashd init <your_custom_moniker>
You can edit this
moniker later, in the
# A custom human readable name for this nodemoniker = "<your_custom_moniker>"
Your full-node keeps unconfirmed transactions in its mempool. In order to protect it from spam, it is better to set a
minimum-gas-prices that the transaction must meet in order to be accepted in your node's mempool. This parameter can be set in the following file
The initial recommended
0.025akash, but you might want to change it later.
# This is a TOML config file.# For more information, see https://github.com/toml-lang/toml##### main base config options ###### The minimum gas prices a validator is willing to accept for processing a# transaction. A transaction's fees must meet the minimum of any denomination# specified in this config (e.g. 10uatom).minimum-gas-prices = "0.025akash"
Next we need to configure the p2p network and ensure that you have the right
genesis.json file to join the testnet.
Fetch the testnet's
genesis.json file into
akashd's config directory.
curl -s https://raw.githubusercontent.com/ovrclk/net/master/latest/genesis.json > $HOME/.akashd/config/genesis.json
Note we use the
latest directory in the testnet repo which contains details for the testnet like the latest version and the genesis file.
To verify the correctness of the configuration run:
Your node needs to know how to find peers. You'll need to add healthy seed nodes or persistent peers to
net repo contains information about the seed nodes and sentry nodes maintained by the Akash team.
You can also ask for peers on the Validators Riot Room
For more information on the how and why of seeds and peers, you can read this great documentation from the Tendermint maintainers.
Transactions on the Akash Network need to include a transaction fee in order to be processed. This fee pays for the gas required to run the transaction. The formula is the following:
fees = ceil(gas * gasPrices)
gas is dependent on the transaction. Different transaction require different amount of
gas amount for a transaction is calculated as it is being processed, but there is a way to estimate it beforehand by using the
auto value for the
gas flag. Of course, this only gives an estimate. You can adjust this estimate with the flag
1.0) if you want to be sure you provide enough
gas for the transaction.
gasPrice is the price of each unit of
gas. Each validator sets a
min-gas-price value, and will only include transactions that have a
gasPrice greater than their
fees are the product of
gasPrice. As a user, you have to input 2 out of 3. The higher the
fees, the higher the chance that your transaction will get included in a block.
::: tip For Akash testnets, the recommended
There are three strategies for pruning state, please be aware that this is only for state and not for block storage:
PruneEverything: This means that all saved states will be pruned other than the current.
PruneNothing: This means that all state will be saved and nothing will be deleted.
PruneSyncable: This means that only the state of the last 100 and every 10,000th blocks will be saved.
By default every node is in
PruneSyncable mode. If you would like to change your nodes pruning strategy then you must do so when the node is initialized. For example, if you would like to change your node to the
PruneEverything mode then you can pass the
---pruning everything flag when you call
Note: When you are pruning state you will not be able to query the heights that are not in your store. The sentry nodes the Akash team is running will be
--pruning nothingand all data from the testnet will be queriable there.
Start the full node with this command:
akashd start --pruning everything
If you would like to run your node via
systemd please see this guide.
You can use
akashctl to check that everything is running smoothly:
View the status of the network with the testnet explorer.
You now have an active full node. What's the next step? You can upgrade your full node to become a Akash Validator. Validators have the ability to propose new blocks the Akash testnet. If you are interested you can continue onto the Validator Setup.
