Solutions that use OpenTimestamps
Support desk
Ask a curator about OpenTimestamps
A human from the House reads every question. Curators answer in plain words and say when they do not know. They will never ask for your seed phrase or keys.
OpenTimestamps's curators
No curator yet. Know OpenTimestamps well? Become its curator: keep this portal true, answer its questions, and earn points and a place on the board.
Reward real users through the House
For founders. Reward campaigns reach people who actually used OpenTimestamps, verified by what they did in the House, not bots or wallets farmed by scripts. You set the reward and who it is for. The House never promises users a reward; it only routes yours to the people who earned it.
