I've been using EVM blockchain as an immutable registry / ledger to record small bits of data linked to IPFS to record events. These are supposed to be immutable by me or anyone else (essentially they act like logs and events).

Is there "regular" immutable events database like this that I don't have to host myself, has a super easy-to-use API, and costs less than $5/mo, but keeps my data around after I stop paying for it?

Do you use a standalone EVM node or mainnet? Recording small bits of data on mainnet must cost you hundreds of dollars in gas fees? If it’s your own personal blockchain then why not use a regular database?

oh! I'm actually using Matic, and all I'm doing is posting a URL that either points to IPFS or my API endpoint.

Yes I know, the API endpoint is silly and mutable and it actually links to my Airtable API lol, but this helps me track "when/where" that I don't want to track on a regular DB.

To date the entire thing's cost less than $10, and I have maybe 30-40 posts. Definitely not production yet though

I have seen Twitter used for publishing small bits of immutable data - not perfect but covers a lot of use cases.

Tweets can be deleted though - that’s not an immutable store of data.

GitHub. A Twitter account.

Both constantly censor and delete data they don't want on their platform.

That’s actually the only reason it’s usable for this. Because you can’t use a public database for anything at all once it’s full of spam and CSAM; not only will it get blocked but nobody will work on maintaining it.

I've thought about using Github and using Github Actions to roll up different people's GH accounts' data into a "central ledger" but yeah, this isn't immutable and Github Actions keeps going down lol.

Twitter is a no-go since their API changes fairly frequently and I still feel burned from their API rug pull a decade ago.
