Choose a size and a duration#
- Open Lock. Pick a size: 0.1, 1 or 10 ZEC. These are the only sizes the pool accepts.
- Pick how many epochs: the app offers 1, 2, 3, 4, 6 or 8. The pool allows up to 8.
- Confirm. Your browser proves that the size comes out of your notes; the rest comes back as change.
Why fixed sizes#
An odd amount is a fingerprint: 3.14159 ZEC locked at 14:02 and 3.14159 ZEC unlocked later are easy to pair. With three sizes, every locked note looks like many others of the same size.
When it earns#
A note locked during epoch k until epoch L earns for epochs k+1 to L. The epoch in which you lock does not count: its list of eligible notes was fixed when it opened, so nobody can lock at the last second and take a share.
What others can see#
The size and the end epoch of a lock are public: the pool needs them to keep the schedule of active stake. Which of your notes paid for it, and who you are, are not. The change goes back to you as a new private note.
Cost#
posl sends the lock for you, so your wallet pays nothing and does not appear. A lock may carry a small fee, at most 0.01 ZEC; today the app sends locks with no fee. See Fees and costs.
Locked ZEC cannot move until the lock ends. Only lock what you will not need for that many epochs.
