What is the current size of the chain? I’m setting up a personal DEX explorer and would love to contribute its development. The guide states it requires about 200 GB of persistent storage, growing at approximately 20 GB per week. Should I assume it’s around 300 GB now? I have 300 GB free—do I need to acquire more storage for the indexers? Thanks!
The current size of the mainnet chain is approximately 100GB. It’s wise to plan upwards, to accommodate for extracting from archives and creating backups, so the 300GB you have available sounds fine to get started.
If it’s your first time running a Penumbra node, consider using the testnet first to try things out, so you’re comfortable with the tooling. Because you mentioned running the DEX explorer specifically, make sure you’re familiar with the documentation on event indexing, which requires additional software, including a database.

Another thing to note is that the node storage requirements are currently higher than they could be, because some space optimizations (like pruning old nodes of the JMT) are not implemented – they weren’t on the critical path for mainnet – so the size could probably be shrunk in the future.
