I want to know the total size (in GB or TB) of the database on a node that has a copy of the entire Polygon Mainnet chain, so I can allocate resources for a production instance.

How can I know that? I don't want the recommended size I should have, I want the actual size.

  • Would you explain what exactly do you mean? Are you looking to determine current size of the blockchain?

As of March 22, 2023, the total size of Polygon Mainnet is about 1269.05 GB. You can find this information on the Polygon snapshots website: https://snapshots.polygon.technology


Hi developer advocate from Chainstack here.

That depends on the client and the mode of the node(light node/full node/archive node).

To run a full node using Polygon's own bor client takes minimum:

RAM: 16-32 GB
CPU: 8-16 core CPU (For AWS: t3.2xlarge)
Storage: 2.5TB to 5TB SSD (make sure it is extendable)


For an archive node:

RAM: 64 GB
CPU: 16-core CPU
Storage: 10+ TB

Erigon is another popular EVM client, it usually takes fewer resources for archive mode. You can find its system requirement here.

Usually running a node by oneself is quite costly. Syncing a full node will take multiple days, and you need to spend a lot of effort to maintain it. I strongly encourage you to try RPC providers like us instead of setting it up on your own.

It is just much cheaper and hassle-free.

  • Thank you but I just want to know the actual size of the chain in GB. Commented Mar 23, 2023 at 4:31
  • The Chain itself can't be measured in the size of storage volume. If you really want a number, 2.5 TB is the minimum storage size required for a bor node according to the official doc. Commented Mar 23, 2023 at 4:34

    Why can't the chain be measured in the size of storage volume? Commented Mar 23, 2023 at 5:08
  • A blockchain network is simply multiple connected nodes. Those nodes work together to achieve consensus - meaning the same state for account balance, smart contract, etc. Transactions are packed in blocks, when nodes receive a new block they update their local database.

    I don't have the exact number right now. The number I provided is actually the minimum system requirement. Base on my best knowledge, you should follow it. Commented Mar 23, 2023 at 6:07

The actual size of a blockchain can be measured for archive node size since archive nodes include literally everything on-chain.

This article, dated July 2023, says it's bigger than 16 TB. As of today, I would guess 20+ TB.
