Archive Nodes

Archive All Blockchain Data.

An archive node keeps all the past blocks. An archive node makes it convenient to query the past state of the chain at any point in time. Finding out what an account's balance, stake size, etc at a certain block was, or which extrinsics resulted in a certain state change are fast operations when using an archive node. However, an archive node takes up a lot of disk space - nearly 1.2TB for secret-4 as of May 31, 2022.
  • 32GB RAM
  • 2TB 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
Note that syncing from scratch/following these instructions takes several weeks.
To setup your archive node you can follow the instructions below:

Install secretd 1.2.2

Download the secretd .deb
wget https://github.com/scrtlabs/SecretNetwork/releases/download/v1.2.2/secretnetwork_v1.2.2_mainnet_amd64.deb
# check the hash of the downloaded binary
echo "1a51d3d9324979ef9a1f56023e458023488b4583bf4587abeed2d1f389aea947 secretnetwork_v1.2.2_mainnet_amd64.deb" | sha256sum --check

Install `secretd`

sudo dpkg -i secretnetwork_v1.2.2_mainnet_amd64.deb
# verify installation
secretd version
# 1.2.2

Setup SGX

Setup SGX. For more information on SGX, see instructions for setup and verification. See registration if you'd like a more comprehensive overview on what's happening in these steps.

Setup the Node

Execute steps 2 through 8 of Running a Full Node.
Do NOT begin syncing yet!

Set Pruning Parameter

pruning="nothing"
sed -i -e "s/^pruning *=.*/pruning = \"$pruning\"/" $HOME/.secretd/config/app.toml

Optimizations

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 check out this document by [ block pane ] for fine-tuning your machine for better uptime.

Begin Syncing

Note that the secret-node system file is created in a previous step.
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
