## AI overview

The article explains how the Go Checksum Database verifies module source and helps protect against altered tags and targeted versions. It argues that viewing code directly on GitHub can bypass this verification, using a malicious BoltDB module incident as an example, and recommends fetching source with Go tooling for review.

## Source excerpt

Code hosts like GitHub don't necessarily show the correct source of Go modules. pkg.geomys.dev is a new convenient viewer for module source.
