Cosmos Snapshots

Cosmos is a decentralized ecosystem of independent parallel blockchains each using BFT consensus algorithms like Tendermint consensus, that can scale and interoperate.Cosmos envisions simplifying blockchain development for developers and removing the boundaries between blockchains by allowing them to transact with each other. Cosmos aims to establish an Internet of Blockchains, where various blockchains can interact with one another in a decentralized manner. It empowers blockchains to preserve their sovereignty, process transactions quickly, and engage with other blockchains within the ecosystem, making it a versatile solution for numerous applications.

Cosmos testnet Snapshot

Versionv17.0.0-rc0
Creation Date
Last Updated
Block Number6666066
Pruning modePruned
Size13G
Download Cosmos testnet Snapshot

How to use

Download the snapshot

wget https://snapshots.bwarelabs.com/cosmos/testnet/cosmos20240528.tar.lz4

If Cosmos was already on your machine, stop your Cosmos service

sudo systemctl stop cosmos.service

OR container

docker stop <COSMOS_CONTAINER_NAME>

AND make sure there is no process running that might try to write to the database

ps -ef | grep cosmos

Make sure your cosmos data directory is clean (let us assume <COSMOS_HOME> is your root Cosmos directory)

make sure to backup your priv_validator_state.json file before deleting the contents of the data directory

mv <COSMOS_HOME>/data/priv_validator_state.json <COSMOS_HOME>

rm -rf <COSMOS_HOME>/data/

Make sure you have lz4 installed

sudo apt-get install lz4

Decompress the archive

lz4 -c -d cosmos20221208.tar.lz4 | tar -x -C <COSMOS_HOME>

Copy back the priv_validator_state.json file

rm <COSMOS_HOME>/data/priv_validator_state.json

mv <COSMOS_HOME>/priv_validator_state.json <COSMOS_HOME>/data/

Start the Cosmos service OR container!

What is Cosmos snapshot?

Our Cosmos snapshot can be particularly valuable when syncing a new node to the testnet or mainnet network. Instead of downloading and validating the entire blockchain from scratch, a new node can use a snapshot to quickly synchronize within the network.

Why use our Cosmos snapshot?

Using our snapshots during the setup of full Cosmos chain nodes can significantly speed up the syncing process by skipping the validation of all data. This can greatly enhance the speed of the setup. Instead of syncing from scratch with other nodes, you can utilize our Cosmos snapshot to sync faster.

What is the block number of Cosmos Snapshot?

A node snapshot is a snapshot of the blockchain at a specific point in time, and it includes data and state of the blockchain up until that block number. The block number determines the specific point in the blockchain's history that the snapshot represents.

The current block number of Cosmos testnet snapshot is 6666066

The current block number of Cosmos mainnet snapshot is 0

How often is the Cosmos snapshot updated?

Regular updates are made to ensure accurate and up-to-date information. The frequency of the updates depends on the specific data being captured. We regularly update our snapshots to reflect the most recent and accurate state of the Cosmos chain.

How long does it take to restore a node using Cosmos Snapshot?

The time it takes to restore a node using a snapshot can vary depending on several factors, including the size of the snapshot file and the performance of the underlying hardware. In general, the process involves transferring the snapshot data to the node's storage and then initializing the node from that snapshot. For smaller snapshots, the restoration process can be relatively quick and may take just a few minutes. However, for larger snapshots or in cases where the network or storage infrastructure is slower, the restoration process can take longer, potentially several hours.

The Cosmos testnet size is 13G.

The Cosmos mainnet size is 31M.

What does it mean if a snapshot is pruned?

The pruning of a node snapshot refers to the process of removing unnecessary data from the blockchain database to optimize storage space while keeping the integrity of the data. Pruning allows nodes to store only the most essential information needed for the blockchain's operation while discarding older and less relevant data.

The Cosmos testnet snapshot is pruned.

The Cosmos mainnet snapshot is pruned.

What is the main difference between pruned and archival nodes?

Pruned and archival node snapshots are two different approaches to storing blockchain data in a more efficient manner. Pruned node snapshots prioritize storage efficiency by discarding older transaction data, while archival node snapshots prioritize preserving the complete blockchain state.
