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 2TB for secret-4 as of Feb 1, 2023.

Recommended Requirements

• 32GB RAM

• 3TB 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

More on hardware support here.

Note that syncing from scratch/following these instructions takes several weeks, since state-sync is not available for Archive Nodes.

To setup your archive node you can follow the instructions below:

Install latest secretd

Download the secretd .deb from the latest release.

Note: As of writing these lines the latest release is v1.6.0 will be referenced as so for the rest of this document.

Node: Archive nodes are only available with goleveldb. If this doesn't mean anything to you, just proceed with this guide as usual.

# Get the v1.6.0 binaries
wget "https://github.com/scrtlabs/SecretNetwork/releases/download/v1.6.0/secretnetwork_1.6.0_mainnet_goleveldb_amd64.deb"

# Verify the v1.6.0 binaries
echo 'ce9ba85d346fa460ed3fc98871f2a254b269fafa835fc555c9184f6405d8c80a  secretnetwork_1.6.0_mainnet_goleveldb_amd64.deb' | sha256sum --check

Install secretd

sudo dpkg -i secretnetwork_1.6.0_mainnet_goleveldb_amd64.deb

# verify installation
secretd version
# 1.6.0

Setup the Node

Setup the node using the Running a Full Node guide. You should stop at the Set minimum-gas-price Parameter step.

Do NOT begin syncing yet!

Install v1.2.0-archive secretd

Now that you have registered the node with the latest version, install v1.2.0-archive.

# Get the v1.2.0-archive binaries
wget "https://github.com/scrtlabs/SecretNetwork/releases/download/v1.2.0-archive/secretnetwork_1.2.0-archive_amd64.deb"

# Install the v1.2.0-archive binaries
sudo dpkg -i secretnetwork_1.2.0-archive_amd64.deb

Set Pruning Parameter

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

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). It might take a while for blocks to start streaming, so grab some 🍿 while you wait!

journalctl -f -u secret-node

You now have an Archive node running!

Execute upgrades

Syncing a node from scratch means that from time to time you'll need to perform an upgrade (at the block height that the upgrade was originally took place on mainnet).

You will need to use the designated archive-node binaries when available. For the rest of the upgrades, use the binaries for the respective version from the releases page.

As of the writing of these lines, the upgrade timing (in block-height) are:

• v1.3.0 - block height 3,343,000 (binaries).

• v1.4.0 - block height 5,309,200 (binaries).

• v1.5.0 - block height 5,941,700 (binaries).

• v1.6.0 - block height 6,537,300 (binaries).

For more detailed upgrade instructions, you can refer to the v1.5.0 upgrade instructions.
