+### Verifying the release signatures
+
+If you download the pre-built binaries, you can check their
+[Sigsum](https://www.sigsum.org) proofs, which are like signatures with extra
+transparency: you can cryptographically verify that every proof is logged in a
+public append-only log, so you can hold the age project accountable for every
+binary release we ever produced. This is similar to what the [Go Checksum
+Database](https://go.dev/blog/module-mirror-launch) provides.
