# Impost

Impost /ˈimˌpōst/ _noun_ a tax or compulsory payment

Impost is a PoW anti-spam solution, or for short, a PoW captcha. Instead of
spying on your users and using heavy captchas, Impost uses PoW to impose a cost
on sending requests. To a single user, this is a negligable few seconds, but at
scale, it can be a significant deterrent to spam.

This is the impost monorepo, containing the following packages:

- `@impost/widget`: A web component that can be used to embed an Impost widget
  in your website.
- `@impost/lib`: A library that can be used to generate, solve, and verify
  proofs.

It also contains a `solver` package, which is the PoW solver written in Zig,
`@impost/lib` is built on top of, an example of how to use the solver in a
nuxt 3 project.
