Setup Full Node
This document details how to join the Secret Network
secret-4
mainnet as a full node. Once your full node is running and state synced to the current block, you can turn it into a validator in the optional last step.Secret Network has strict Hardware Requirements. If your machine does not meet them, it will *NOT* work as a node.
- Ubuntu/Debian host (with ZFS or LVM to be able to add more storage easily)
- A public IP address
- Open ports
TCP 26656 & 26657
Note: If you're behind a router or firewall then you'll need to port forward on the network device. - RPC address of an already active node. You can use any node that exposes RPC services.
- 32GB RAM
- 512GB SDD
- 1 dedicated core of any Intel Skylake processor (Intel® 6th generation) or better (Xeon gen3 (Ice Lake) NOT supported)
- Motherboard with support for SGX in the BIOS
- 32GB RAM
- 1TB NVMe SSD
- 2 dedicated cores of any Intel Skylake processor (Intel® 6th generation) or better (Xeon gen3 (Ice Lake) NOT supported)
- Motherboard with support for SGX in the BIOS
This guide assumes you've already installed the latest version of secretd and SGX. To setup an archive node, you must follow the Archive Nodes instructions.
For more information on SGX, see instructions for SGX Installation and Verifying SGX. See Node Registration Information if you'd like a more comprehensive overview on what's happening in these steps.
Choose a moniker for yourself, and replace
<MONIKER>
with your moniker below. This moniker will serve as your public nickname in the network.secretd init <MONIKER> --chain-id secret-4
This will generate the following files in
~/.secretd/config/
genesis.json
node_key.json
priv_validator_key.json
The genesis file is how other nodes on the network know what network you should be on.
wget -O ~/.secretd/config/genesis.json "https://github.com/scrtlabs/SecretNetwork/releases/download/v1.2.0/genesis.json"
# verify genesis.json checksum
echo "759e1b6761c14fb448bf4b515ca297ab382855b20bae2af88a7bdd82eb1f44b9 $HOME/.secretd/config/genesis.json" | sha256sum --check
Initialize
/opt/secret/.sgx_secrets
:mkdir -p /opt/secret/.sgx_secrets
WARNING: This method is experimental, and may not work. If it doesn't work, skip to manual registration.
The following commands will create the necessary environment variables and attempt to automatically register the node.
export SCRT_ENCLAVE_DIR=/usr/lib
export SCRT_SGX_STORAGE=/opt/secret/.sgx_secrets
secretd auto-register
secretd init-enclave
The attestation certificate should have been created by the previous step
ls -lh /opt/secret/.sgx_secrets/attestation_cert.der
Verify the certificate is valid. A 64-character registration key will be printed if it was successful.
PUBLIC_KEY=$(secretd parse /opt/secret/.sgx_secrets/attestation_cert.der 2> /dev/null | cut -c 3-)
echo $PUBLIC_KEY
If registration was NOT succesfull consider checking out the Registration troubleshooting help or contact a fellow validator on our discord.
The following steps should use
secretd
be ran on the full node itself. To run the steps with secretd
on a local machine, set up the CLI there.Configure
secretd
. Initially you'll be using the bootstrap node, as you'll need to connect to a running node and your own node is not running yet.secretd config chain-id secret-4
secretd config node https://lcd-secret.scrtlabs.com:443/rpc
secretd config output json
If you already have a wallet funded with
SCRT
, you can import the wallet by doing the following:secretd keys add <key-alias> --recover
Otherwise, you will need to set up a key. Make sure you back up the mnemonic and the keyring password.
secretd keys add <key-alias>
This will output your address, a 45 character-string starting with
secret1...
.- 1.Register your node on-chain
secretd tx register auth /opt/secret/.sgx_secrets/attestation_cert.der -y --from <key-alias>
2. Pull & check your node's encrypted seed from the network
SEED=$(secretd query register seed $PUBLIC_KEY | cut -c 3-)
echo $SEED
3. Get additional network parameters
These are necessary to configure the node before it starts.
secretd query register secret-network-params
ls -lh ./io-master-key.txt ./node-master-key.txt
From here on, commands must be ran on the full node.
mkdir -p ~/.secretd/.node
secretd configure-secret node-master-key.txt $SEED
In order to be able to handle NFT minting and other Secret Contract-heavy operations, it's recommended to update your SGX memory enclave cache:
sed -i.bak -e "s/^contract-memory-enclave-cache-size *=.*/contract-memory-enclave-cache-size = \"15\"/" ~/.secretd/config/app.toml
We recommend
0.0125uscrt
per gas unit:perl -i -pe 's/^minimum-gas-prices = .+?$/minimum-gas-prices = "0.0125uscrt"/' ~/.secretd/config/app.toml
Your node will not accept transactions that specify
--fees
lower than the minimun-gas-price
you set here.Note that the
secret-node
system file is created when installing sgx.sudo systemctl enable secret-node && sudo systemctl start secret-node
If everything above worked correctly, the following command will show your node streaming blocks (this is for debugging purposes only, kill this command anytime with Ctrl-C).
journalctl -f -u secret-node

You are now a full node. 🎉
secretd tendermint show-node-id
And publish yourself as a node with this ID:
<your-node-id>@<your-public-ip>:26656
Be sure to point your CLI to your running node instead of the bootstrap node
secretcli config node tcp://localhost:26657
If someone wants to add you as a peer, have them add the above address to their persistent_peers in their ~/.secretd/config/config.toml.
And if someone wants to use your node from their secretcli then have them run:
secretcli config chain-id secret-4
secretcli config output json
secretcli config indent true
secretcli config node tcp://<your-public-ip>:26657
