2025-09-17[chore] remove nollamas middleware for now (after discussions with a ↵Libravatar kim1
security advisor) (#4433) i'll keep this on a separate branch for now while i experiment with other possible alternatives, but for now both our hacky implementation especially, and more popular ones (like anubis) aren't looking too great on the deterrent front: https://github.com/eternal-flame-AD/pow-buster Co-authored-by: tobi <tobi.smethurst@protonmail.com> Reviewed-on: https://codeberg.org/superseriousbusiness/gotosocial/pulls/4433 Co-authored-by: kim <grufwub@gmail.com> Co-committed-by: kim <grufwub@gmail.com>
2025-05-26[feature] update proof-of-work to allow setting required rounds (#4186)Libravatar kim1
# Description This updates our proof-of-work middleware, NoLLaMas, to work on a more easily configurable algorithm (thank you f0x for bringing this to my attention!). Instead of requiring that a solution with pre-determined number of '0' chars be found, it now pre-computes a result with a pre-determined nonce value that it expects the client to iterate up-to. (though with some level of jitter applied, to prevent it being too-easily gamed). This allows the user to configure roughly how many hash-encode rounds they want their clients to have to complete. ## Checklist - [x] I/we have read the [GoToSocial contribution guidelines](https://codeberg.org/superseriousbusiness/gotosocial/src/branch/main/CONTRIBUTING.md). - [x] I/we have discussed the proposed changes already, either in an issue on the repository, or in the Matrix chat. - [x] I/we have not leveraged AI to create the proposed changes. - [x] I/we have performed a self-review of added code. - [x] I/we have written code that is legible and maintainable by others. - [x] I/we have commented the added code, particularly in hard-to-understand areas. - [x] I/we have made any necessary changes to documentation. - [ ] I/we have added tests that cover new code. - [x] I/we have run tests and they pass locally with the changes. - [x] I/we have run `go fmt ./...` and `golangci-lint run`.
