Public transparency log

Every HQ case chain and every HQ tool chain has a latest seal, called its head. This log keeps those heads, and only the heads. No case names, people or content are in it. Each day the heads are built into one Merkle tree, and the tree's root is sealed. Anyone can check that a head was logged, without signing in.

Sealed days

One period is one UTC day. A day is sealed after it ends. Empty days are sealed too, so a missing day shows.

Paste a chain ID and a head. Your browser rebuilds the path to the day's root and checks it. It trusts nothing it cannot recompute.
