ARCHIVE / Performance Analysis of My Celestia Light Node
The past year has been incredibly productive and filled with experiences for me. One of these experiences was undoubtedly the Celestia Blockspace Race incentivized testnet. As I reflect on what I've accomplished this year, this article I wrote during the testing phase comes to mind. While the content may no longer be current, it's reassuring to know it's here when I look back. Enjoy the read!
Introduction
Celestia is the first modular blockchain network. It’s mission is to make deploying a blockchain as easy as deploying a new smart contract. Celestia introduces what is called the data availability layer for enabling efficient scaling and allowing L2 rollups to do data sampling for transactions they need.
Blockspace Race is the incentivized testnet that will help the Celestia network take the steps to solidify its capabilities and prepare node operators for mainnet launch.
Blockspace Race incentivized testnet started on March 29 and I’m running a light node. I’m very lucky to be able to contribute and be a part of this exciting process.
I moved my node, which was running on March 29, to a different server on April 7 due to the network problem of the service provider. For this reason, the evaluations in question cover the dates of 7–13 April.
Minimum recommended hardware requirements to run a light node
