Spam Welcome

March 11, 2026 ·

This blog now includes a comments section. But not just any comments section, rather a comment section that may sound silly at first. The idea is to have a cost attached to actions that in large numbers may prove to be junk or spam. This has many benefits, two of my favorites being: I don't have to moderate comments, and I get to gain from any potential spam. The simple rule is:

One must pay ~1 USDC to write a comment.

Pricing via Processing (or Combatting Junk Mail) was a pivotal paper written in 1992 by Cynthia Dwork and Moni Naor that proved to be an intellectual ancestor to blockchains. In this paper, they describe a computational technique for combatting junk mail in particular and controlling access to a shared resource in general.

Brilliant. All spam welcome.
