Run A Full Node

How To Join Secret Network as a Full Node on Testnet
This document details how to join the Secret Network testnet as a full node. Once your full node is running, you can turn it into a validator in the optional last step.
Requirements
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.
Reading Tendermint: Running in production​
RPC address of an already active node. You can use bootstrap.secrettestnet.io:26657, or any other node that exposes RPC services. Alternate RPC nodes available in the API Registry.
​Install SGX​
Minimum Requirements
16GB RAM
150GB SSD for Prune Everything, or default pruning. 1TB premium SSD for Archive nodes.
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
Recommended Requirements
32GB RAM
512GB 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
Installation
Install SGX and secretd
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.
Initialize Secret Network Configs
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 pulsar-2
This will generate the following files in ~/.secretd/config/
genesis.json
node_key.json
priv_validator_key.json
Download genesis.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://storage.googleapis.com/stakeordie-pulsar-2/genesis.json"
# verify genesis.json checksum
echo "a48a5c2ba3f0d0ee077fc9a24514caaed3914e23e0de7b88163bb4d25e0866b8 $HOME/.secretd/config/genesis.json" | sha256sum --check
Initialize Secret Enclave
Initialize /opt/secret/.sgx_secrets:
mkdir -p /opt/secret/.sgx_secrets
You can choose between two methods, 3a (automatic) or 3b (manual):
Initialize Secret Enclave - Automatic Registration (EXPERIMENTAL)
WARNING: This method is experimental, and may not work. If it doesn't work, skip to step 3b.
The following commands will create the necessary environment variables and attempt to automatically register the node.
export SCRT_ENCLAVE_DIR=/usr/lib
export SCRT_SGX_STORAGE=/opt/secret/.sgx_secrets
secretd auto-register
If this step was successful, you can skip straight to step 9.
Initialize Secret Enclave - Manual Registration
secretd init-enclave
Verify Enclave Initialization
Attestation certificate should have been created by the previous step
ls -lh /opt/secret/.sgx_secrets/attestation_cert.der
Verify the certificate is valid. A 64 character registration key will be printed if it was successful.
PUBLIC_KEY=$(secretd parse /opt/secret/.sgx_secrets/attestation_cert.der  2> /dev/null | cut -c 3-)
echo $PUBLIC_KEY
Configure secretd
The following steps should use secretd be ran on the full node itself. To run the steps with secretd on a local machine, set up the CLI there.
Configure secretd. Initially you'll be using the bootstrap node, as you'll need to connect to a running node and your own node is not running yet.
secretd config chain-id pulsar-2
secretd config node https://rpc.pulsar.scrttestnet.com
secretd config output json
Fund Secret Wallet
If you already have a wallet funded with SCRT, you can import the wallet by doing the following:
secretd keys add <key-alias> --recover
Otherwise, you will need to set up a key. Make sure you back up the mnemonic and the keyring password.
secretd keys add <key-alias>
This will output your address, a 45 character-string starting with secret1.... Copy/paste it to get some test-SCRT from the faucet. Continue when you have confirmed your account has some test-SCRT in it.
Configure Node Attestation
1.Register your node on-chain
secretd tx register auth /opt/secret/.sgx_secrets/attestation_cert.der -y --from <key-alias>
2. Pull & check your node's encrypted seed from the network
SEED=$(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-cert.der ./node-master-cert.der
Configure Your Secret Node
From here on, commands must be ran on the full node.
mkdir -p ~/.secretd/.node
secretd configure-secret node-master-cert.der $SEED
Add Seeds And Persistent Peers To Configuration File.
# seeds
perl -i -pe 's/seeds = ""/seeds = "7a421a6f5f1618f7b6fdfbe4854985746f85d263\@108.62.104.102:26656,a72e376dca664bac55e8ce55a2e972a8ae2c995e\@144.202.126.98:26656,a941999e72f4726d276ef055a09cb8bedf8e7a9a\@45.35.77.30:26656,f95ba3da4a9eec559397f4b47b1539e24af6904c\@52.190.249.47:26656"/' ~/.secretd/config/config.toml
​
# persistent_peers
perl -i -pe 's/persistent_peers = ""/persistent_peers = "7a421a6f5f1618f7b6fdfbe4854985
Optimization
In order to be able to handle NFT minting and other Secret Contract-heavy operations, it's recommended to update your SGX memory enclave cache:
sed -i.bak -e "s/^contract-memory-enclave-cache-size *=.*/contract-memory-enclave-cache-size = \"15\"/" ~/.secretd/config/app.toml
Also checkout this document by [ block pane ] for fine tuning your machine for better uptime.
Set minimum-gas-price Parameter
We recommend 0.0125uscrt per gas unit:
perl -i -pe 's/^minimum-gas-prices = .+?$/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.
Enable secret-node:
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. 🎉
Get Node ID
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 pulsar-2
secretcli config output json
secretcli config indent true
secretcli config node tcp://<your-public-ip>:26657
State Sync
You can skip syncing from scratch or download a snapshot by State Syncing to the current block.
Optional: Become a Validator
To turn your full node into a validator, see Join Testnet as a Validator.
